ABSTRACTBackground: Post-traumatic stress disorder (PTSD) is a common and debilitating disorderwhich has a significant impact on the lives of sufferers. A number of early psychologicalinterventions have been developed to try to prevent chronic difficulties.Objective: The objective of this study was to establish the current evidence for the effec-tiveness of multiple session early psychological interventions aimed at preventing or treat-ing traumatic stress symptoms beginning within three months of trauma exposure.Methods: Randomized controlled trials of early multiple session psychological interventionsaimed at preventing or reducing traumatic stress symptoms of individuals exposed toa traumatic event, fulfiling trauma criteria for an ICD or DSM diagnosis of PTSD were identifiedthrough a search of the Cochrane Common Mental Disorders Group Clinical Trials Registersdatabase, the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, PsycINFO andPILOTS. Two authors independently extracted study details and data and completed risk of biasassessments. Analyses were undertaken using Review Manager software. Quality of findingswere rated according to ‘Grades of Recommendation, Assessment, Development, andEvaluation’ (GRADE) and appraised for clinical importance.Results: Sixty-one studies evaluating a variety of interventions were identified. For indivi-duals exposed to a trauma who were not pre-screened for traumatic stress symptoms therewere no clinically important differences between any intervention and usual care. Forindividuals reporting traumatic stress symptoms we found clinically important evidence ofbenefits for trauma-focused cognitive-behavioural therapy (CBT-T), cognitive therapy with-out exposure and eye movement desensitization and reprocessing (EMDR). Differences weregreatest for those diagnosed with acute stress disorder (ASD) and PTSD.Conclusions: There is evidence for the effectiveness of several early psychological interven-tions for individuals with traumatic stress symptoms following trauma exposure, especiallyfor those meeting the diagnostic threshold for ASD or PTSD. Evidence is strongest fortrauma-focused CBT.

Sehan desarrollado una serie de intervenciones psicológicas tempranas para tratar de prevenirdificultades crónicas.Objetivo: El objetivo de este estudio fue establecer la evidencia actual para la eficacia deintervenciones psicológicas tempranas con múltiples sesiones con el objetivo de preveniro tratar síntomas de estrés traumático que comenzaron en los tres meses posteriores a laexposición al trauma.Métodos: Se realizó una búsqueda bibliográfica basada en la base de datos de Cochrane deEstudios Clínicos de Trastornos Mentales Frecuentes, en el registro de ensayos controlados deCochrane, MEDLINE, Embase, PsycINFO y PILOTS, para identificar ensayos controlados rando-mizados de intervenciones psicológicas tempranas de múltiples sesiones que tenían el objetivode prevenir o reducir síntomas de estrés traumático en individuos expuestos a un eventotraumático, y que cumplían los criterios de TEPT según la CIE o el DSM. Dos autores indepen-dientes extrajeron los detalles e información del estudio y completaron una evaluación deriesgo de sesgo. Se llevaron a cabo análisis usando el software Review Manager. La calidad delos hallazgos fue puntuada según los ‘Grados de Recomendación, Valoración, Desarrolloy Evaluación’ (GRADE pos sus siglas en inglés) y evaluada por su importancia clínica.Resultados: Se identificaron sesenta y un estudios que evaluaban una variedad de interven-ciones. Para aquellos individuos que estuvieron expuestos a un trauma que no tuvieron una pre-evaluación de síntomas de estrés traumático no hubo una diferencia clínica importante entrecualquier intervención y cuidado usual. Para los individuos que reportaron síntomas de estrés

近期创伤后的早期心理干预:系统综述和元分析
背景:创伤后应激障碍(PTSD)是一种常见的, 使人衰弱的疾病,对患者的生活有重大影响。为预防发展为慢性疾病,已经开发出许多早期心理干预措施。
目标:本研究的目的是为旨在预防或治疗创伤暴露三个月内开始出现的创伤应激症状的多阶段早期心理干预的有效性建立现有证据。
方法:通过搜索Cochrane常见精神障碍小组临床试验注册数据库, Cochrane 临床对照试验数据库, MEDLINE, Embase, PsycINFO 和 PILOTS,确定了早期多阶段心理干预的随机对照试验。这些干预旨在预防或减轻遭受创伤事件且符合 ICD 或 DSM 诊断 PTSD 的创伤标准的个体的创伤应激症状。两位作者分别独自提取了研究细节和数据,并完成了误差风险评估。使用 Review Manager 软件进行分析。根据‘推荐分级的评估, 制定与评价’(GRADE)对结果的质量进行评级并评估其临床重要性。
结果:确定了评估多种干预措施的61项研究。对于有创伤暴露但未预先筛查创伤应激症状的个体,任何干预措施和日常护理间均无重要的临床差异。对于报告有创伤应激症状者,我们发现聚焦创伤的认知行为疗法(CBT-T), 无暴露认知疗法以及眼动脱敏与再加工(EMDR)效益的重要临床证据。在被诊断为急性应激障碍(ASD)和 PTSD 的患者中差异最大。
结论:有证据表明了对于创伤暴露后患有创伤应激症状者,特别是那些达到 ASD 或 PTSD诊断阈值的个体,几种早期心理干预的有效性。对于聚焦创伤的 CBT 证据最充分。
1. Introduction
Numerous studies demonstrate that a range of traumaticexperiences can cause psychological difficulties to thoseexposed (Berger et al., 2012, Brunet, Monson, Liu, &Fikretoglu, 2015; Dworkin, Menon, Bystrynski, & Allen,2017; Lowe & Galea, 2017; Neria, Nandi, & Galea, 2008).For many, these difficulties are short lived or subclinical,and diminish over time without the need for medical orpsychological intervention (Giummarra, Lennox, Dali,Costa, & Gabbe, 2018; McNally, Bryant, & Ehlers,2003). However, psychological difficulties may developand persist for some of those exposed. These difficultiesinclude acute stress disorder (ASD) and post-traumaticstress disorder (PTSD). Around a third of individualswith PTSD at 4–6 weeks post trauma exposure remit by3 months (Santiago et al., 2013); whilst for aroundanother third of individuals symptoms become chronicand unremitting (Kessler, Sonnega, Bromet, Hughes, &Nelson, 1995; Santiago et al., 2013). Estimated life-timeprevalence rates of PTSD have been found to vary from1.3% to 8.8% (Atwoli, Stein, Koenen, & McLaughlin,2015). Rates of PTSD also vary according to traumatype, with an estimated mean conditional risk followingany trauma exposure of 4.0%, with much higher rates forsome types of interpersonal trauma (Kessler et al., 2017)which tend not to show the same pattern of symptomreduction (Santiago et al., 2013). PTSD symptoms canhave a considerable impact on the life trajectory of thoseexposed to trauma and their families (McFarlane, 2010;Shalev et al., 2019). Typically, symptoms affect social,
occupational and interpersonal functioning, and physicalhealth. PTSD is frequently associated with comorbidityand unhealthy coping mechanism, which can becomechronic and entrenched over time (Shalev et al., 2019).PTSD has a significant economic burden (Ferry et al.,2015; Greenberg et al., 1999).
As the effects of trauma exposure and the develop-ment of conditions such as PTSD have become betterunderstood, there have been increasing efforts todevelop psychological and pharmacological interven-tions that might prevent the onset of disorder or ame-liorate early symptoms (Kearns, Ressler, Zatzick, &Rothbaum, 2012; McNally et al., 2003). For a time,Psychological Debriefing (also known as CriticalIncident Stress Debriefing) was a widely used form ofearly intervention. However, its use has declined asevidence challenging its efficacy has emerged (Bastos,Furuta, Small, McKenzie-McHarg, & Bick, 2015; Rose,Bisson, Churchill, & Wessely, 2002). Over the past20 years or so, a range of other approaches, mainlybased on established cognitive behavioural therapy(CBT) for PTSD, have emerged (Kearns et al., 2012).More recently some groups have started to evaluatetelephone-based approaches and approaches based onnew technology in order to increase accessibility topotentially effective interventions.
In 2009 we published a systematic review and meta-analysis of randomized controlled trials (RCTs) of psy-chological interventions aimed at preventing or treatingPTSD within three months of a traumatic event
2 N. P. ROBERTS ET AL.
(Roberts, Kitchiner, Kenardy, & Bisson, 2009). Thisreview included 25 studies. We found no evidence tosupport the use of preventative interventions offered toindividuals irrespective of whether they were sympto-matic or not. However, we did find evidence to supportthe use of trauma focused cognitive behavioural therapy(CBT-T) in studies targeting individuals with earlytraumatic stress symptoms. Effects were strongest fortreatment of acute stress disorder and posttraumaticstress disorder. A subsequent review conducted by theUS Agency for Health Care Research and Quality(AHRQ) identified a smaller pool of 19 studies butreported similar findings (Forneris et al., 2013).A review focusing specifically on individuals who suf-fered traumatic injury which included 26mostly rando-mised controlled trials (RCTs) also found support forcognitive behavioural interventions, alongside small butsignificant effects for collaborative care basedapproaches (Giummarra et al., 2018). Neither of thesereviews made a distinction between preventative inter-ventions aimed at all individuals exposed and studiesfocusing specifically on individuals who were sympto-matic. Since our previous review (Roberts et al., 2009),a range of new early interventions have been developedand evaluated, including brief EMDR, new technologybased approaches and interventions aimed at those whohave experienced serious illnesses. In light of new devel-opments in the field, the purpose of this paper is toprovide an update of our previous review of all availableearly intervention studies aiming to prevent or treattraumatic stress symptoms following exposure to anevent fulfilling trauma criteria for an ICD or DSMdiagnosis of PTSD. The review was undertaken asa part of the process for the International Society forTraumatic Stress Studies (ISTSS) Treatment Guidelines(Bisson et al., 2019).
2. Method
2.1. Data sources
Following on from the previous search, we undertooka systematic computerized literature search of theCochrane Common Mental Disorders Group clinicaltrials registers databases for studies published fromJanuary 2008 to May 2016 using the search termsPTSD or posttrauma* or post-trauma* or ‘post trauma*’or ‘combat disorder*’ or ‘stress disorder*’. These data-bases are collated and updated on a weekly basis fromMEDLINE, EMBASE and PsycINFO. A further searchwas undertaken in March 2018. We chose not toexclude any potential study based on date of publica-tion, at any time point. Searches were undertaken aspart of a search process to support development of newPTSD treatment guidelines for the ISTSS (Bisson et al.,2019). See Appendix 1 (online supplement) for detailsof the search terms and parameters. We checked the
reference lists of studies identified in the search, relatedreview articles and management guidelines. We con-tacted authors of unpublished studies that had com-pleted recruitment when there was a registered protocolavailable on a trial register, such as Clinical Trials. Weposted a list of identified studies on the website of theInternational Society for Traumatic Stress website andasked the membership to identify studies that we mighthave missed.
2.2. Study selection
Study selection followed the procedure in our previousreview (Roberts et al., 2009). Study abstracts were readindependently by two of the reviewers to determine ifthey potentially met the inclusion criteria. The fullmanuscript of all studies that either reviewer felt poten-tially met the criteria were obtained and read indepen-dently by two reviewers. To be included, a study had tobe an RCT that considered one or more defined psy-chological intervention or treatment aimed at prevent-ing or reducing traumatic stress symptoms in adultsfollowing events that appeared to fulfill criteria fora traumatic event according to DSM or ICD PTSDdiagnostic descriptions (excluding single session pre-ventative interventions), in comparison witha placebo, other control (e.g. usual care or waiting listcontrol) or alternative psychological treatment condi-tion. All studies had to have been completed and ana-lysed by October 2018 with an available studymanuscript. Presence or absence of symptoms, samplesize, publication status and language of publicationwere not used to determine whether a study should beincluded. The review considered studies involvingadults aged 18 and over only. In cases where therewere a combination of adults and adolescents, at least80% of the sample had to be 18 or over.
2.3. Data extraction
A data extraction sheet was designed to capture datawhich was then entered into Review Management 5(RevMan-5.3) software (Review Manager [RevMan],2014). Information extracted included demographicdetails of participants, inclusion and exclusion criteria,details of the traumatic event, the randomization pro-cess, the interventions used, drop-out rates and out-come data. Study quality was assessed with theCochrane Collaboration’s tool for assessing risk ofbias (Higgins et al., 2011) using the domains: sequencegeneration, allocation concealment (selection bias),blinding of assessors (detection bias), incomplete out-come data (attrition bias), selective outcome reporting,and other sources of bias. Data were extracted andquality assessed by two reviewers independently. Anydisagreements were discussed with a third reviewerand a consensus achieved.

2.4. Data synthesis
In line with our previous review (Roberts et al., 2009)we separated trials into three separate groups:
(1) Studies that have offered intervention beginningwithin three months to any individual exposedto a traumatic event irrespective of their symp-toms with the aim of preventing PTSD.
(2) Interventions begun within three months withthe aim of preventing PTSD or ongoing distressin individuals with traumatic stress symptoms.
(3) Interventions begun within three months withthe aim of treating ASD or PTSD in indivi-duals who already met diagnosis.
In our previous review we combined data from allstudies evaluating interventions aimed at any indi-vidual exposed to a traumatic event irrespective oftheir symptoms in one meta-analysis (Roberts et al.,2009). In contrast, in this review we only combineddata from studies of similar interventions for all theabove groupings. We previously identified severalstudies evaluating CBT-T for individuals with trau-matic stress symptoms. We considered undertakingevaluation of CBT-T studies by specific interventionbut we took the view that there were insufficientstudies following a specific model to make thisapproach meaningful at this time. As previously,CBT-T was defined as any intervention that focusedon the trauma using written, imaginal or in-vivoexposure therapy with or without cognitive therapyand other cognitive behavioural techniques.
Our primary outcome was PTSD symptom sever-ity as this is the outcome most widely reported in thetraumatic stress literature (Bisson, Roberts, Andrew,Cooper, & Lewis, 2013). When an individual studyreported both a clinician-administered and a self-report measure, primacy was given to outcomesusing the clinician-administered measure. PTSDdiagnosis was our other outcome of interest. Weundertook analyses with follow-up data where thiswas available. Time points were decided a priori aspost-treatment, three to six months post-trauma,seven to 12 months post-trauma, one to two yearspost-trauma, and two years and beyond, based on ourknowledge of commonly used follow-up points usedin previous early intervention studies.
Data were analysed for summary effects using theReview Manager 5.3 program (RevMan, 2014). All con-tinuous outcomes were analysed using standard meandifferences (SMD), in order to compare effects acrossanalyses. SMD assumes that all scales are measuring thesameunderlying symptomor condition. Relative riskwascalculated for diagnostic status. 95% confidence intervalswere calculated for all outcomes. Available case analysisand intent to treat analysis with imputation using the lastobservation carried forward method were performedwhen enough information was available. In cases where
there was inadequate information within the paper toperform these analyses further informationwas requestedfrom the lead author.
Heterogeneity between studies was assessed by con-sidering the I2 and chi2 test of heterogeneity. Thisstatistic measures the percentage of variation that isnot due to chance (Fletcher, 2007). An I2 of less than30% was taken to indicate mild heterogeneity anda fixed effects model was used. When the I2 wasgreater or equal to 30% a random-effects model wasused. A visual inspection of the forest plots was used asa test of robustness of these findings. We decideda priori that if a minimum of 10 studies were availablein a meta-analysis, we would prepare funnel plots andexamine them for signs of asymmetry. Where asym-metry was indicated, we planned to consider otherpossible reasons for this. We assessed the quality ofevidence using the ‘Grades of Recommendation,Assessment, Development, and Evaluation’ (GRADE)approach (Guyatt, Oxman, Schünemann, Tugwell, &Knottnerus, 2011, Guyatt et al., 2013; Langendamet al., 2013) using five factors: limitations in studydesign and implementation of available studies, indir-ectness of evidence, unexplained heterogeneity orinconsistency of results, imprecision of effect esti-mates, and potential publication bias. The quality ofevidence for each comparison was graded according toour confidence that the estimate of effect wouldremain unchanged as a result of further research.A high rating indicates that further research is veryunlikely to change our confidence in the estimate ofeffect; a moderate rating indicates that research islikely to have an important impact on the confidencein the estimate of effect and may change the estimate;low quality indicates that further research is very likelyto have an important impact on confidence in theestimate of effect and is likely to change the estimate;very low quality indicates that the estimate of effect isvery uncertain. Finally, we rated findings in terms ofclinical importance. We used a definition of clinicalimportance, which was developed by the ISTSSTreatment Guidelines Committee and approved bythe ISTSS Board and membership (Bisson et al.,2019), building on previous work by the NationalInstitute of Health and Care Excellence (NationalCollaborating Centre for Mental Health, 2005). To berated clinically important, an early intervention had todemonstrate an effect size of >0.5 for continuous out-comes for wait list control comparisons, >0.4 for pla-cebo control comparisons and >0.2 for activetreatment control comparisons. For relative risk out-comes an effect of <0.8 was required. When only onestudy, evaluating a specific intervention, was availableits findings could not be judged as clinically important,unless the sample size was large (>300 participants).Non-inferiority RCT evidence alone was not sufficientto recommend an intervention as clinically important.
4 N. P. ROBERTS ET AL.
Following the procedure undertaken previously(Roberts et al., 2009), to determine the impact of qualityon outcome we decided that we that we would under-take a sensitivity analysis for allocation concealment.Inadequate allocation concealment has been found tohave influence the degree of effect in research trials andis thought to be one of the more important features ofrisk of bias (Hewitt, Hahn, Torgerson, Watson, &Bland, 2005). We therefore decided that we wouldinvestigate whether there was any indication of differ-ential treatment effects through a sensitivity analysis tosee if there was a change in the magnitude of effect andconfidence intervals, excluding studies rated to havea high or unclear risk of bias for allocation concealment.
3. Results
Figure one displays the results of the systematic searches.In addition to the 25 studies and two long-term outcomestudies included in the previous review, 6704 additionaltitles and abstracts were identified as a result of the searchprocess and 204 papers were reviewed in detail by two ofthe authors independently to establish if they met thespecified inclusion criteria. Thirty-six new studies werefound tomeet the inclusion criteria along with one paperreporting long term follow-up data for one of the newlyidentified studies, giving a total of 61 studies plus threelong-term follow-up studies. Twenty seven of the 61studies evaluated preventative interventions, aimed atanyone exposed to the relevant traumatic event; theother 34 studies evaluated early treatment interventions
in individuals with early traumatic stress symptoms; ofthese 14 were studies where participants met diagnosisfor ASD or PTSD. Fifty-nine studies were reported inEnglish, one was in French (Andre, Lelord, Legeron,Reignier, & Delattre, 1997) and one in Persian(Taghizadeh, Jafarbegloo, Arbabi, & Faghihzadeh,2008). A flow diagram of the systematic review can beseen in Figure 1. The characteristics of all studies identi-fied in this search and the previous review are describedin Table 1, with inclusion and exclusion criteria in TableS1 (see online supplement).
3.1. Synthesis of results
The outcomes for individual studies are shown inTable 1. The post intervention and follow-up results ofthe meta-analyses for comparisons that included morethan one study are shown in Table 2 with examples ofForest plots in Figures 2 and 3. The outcomes reportedare severity of PTSD and rates of PTSD.

Ryding et al., 1998, 2004; Wang et al., 2015; Wijesingheet al., 2015; Zatzick et al., 2001) evaluated brief psychoso-cial interventions aimed at preventing PTSD in indivi-duals exposed to a specific traumatic event. All startedwithin one month of the trauma. Seven studies (Bromet al., 1993; Gamble et al., 2005; Gidron et al., 2001, 2007;Marchand et al., 2006; Rothbaum et al., 2012; Rydinget al., 1998) used an approach which we grouped as‘brief individual trauma processing’. These studies eval-uated a number of brief therapies that were theoreticallydiverse but shared similar core treatment components.These included: psychoeducation and therapist directedreliving of the index trauma to promote elaboration of thetrauma memory and help to contextualize or reframeaspects of the experience. We found no statistical differ-ence between brief individual trauma processingapproaches and usual care or a supportive listening con-trol intervention at any time point (see Figure 2). We didfind evidence to support the use of brief CBT baseddyadic therapy over treatment as usual, at 3 months(Brunet et al., 2013; Kazak et al., 2005) but this effectwas not judged clinically important. A single studyshowed a significant difference in PTSD severity for self-guided internet-based intervention over treatment asusual (Mouthaan et al., 2013) at 1 month (N = 300;SMD −0.38 CI −0.61 to −0.15; GRADE low) and3–6 months post trauma (N = 300; SMD −0.27 CI−0.50 to −0.04; GRADE low) but not at 7–12 months(N= 300 SMD0.00CI−0.23 to 0.23; GRADE low). Theseeffects were not judged clinically important. One singlestudy showed no significant difference for intensive carediaries over delayed access to intensive care diaries at3–6 months but did show a significant difference forPTSD diagnosis (N = 322; RR 0.38 CI 0.17 to 0.82;GRADE low).Another single study evaluating telephone-based CBT following cardioverter defibrillator transplant(Irvine et al., 2011) found no difference to usual care at3–6 months but there was a difference at 7–12 months(N = 185; SMD −0.38 CI −0.67 to −0.09; GRADE low).This effect was not judged clinically important.
No differences were found for group counselling(Ryding et al., 2004), a three step parenting interventionfollowing premature birth (Borghini et al., 2014), briefinterpersonal counselling (Holmes et al., 2007), commu-nication facilitator in an intensive care setting (Curtiset al., 2016), supported psychoeducation (Als et al.,2015), a nurse led intensive care recovery program(Jensen et al., 2016), or collaborative care (Zatzick et al.,2001). Six studies did not provide data that we were ableto interrogate because data were not adequately reportedin study papers and we were unable to obtain additionaldata from study authors (Andre et al., 1997; Biggs et al.,2016; Lindwall et al., 2014; Taghizadeh et al., 2008;Wanget al., 2015; Wijesinghe et al., 2015). Of these, one study(Taghizadeh et al., 2008) reported a difference in PTSDseverity for counselling at 3–6 months over usual care(N = 300) for women who had experienced a traumaticTa

3.1.2.

were present at several time points. A post hoc sub-group analysis suggested that effects were largest forinterventions of 12 or more sessions (K = 3; N = 181;SMD −1.11 CI-1.62, −0.61) when compared againstwait list. Statistically significant differences for PTSDseverity were also found for cognitive therapy withoutexposure and EMDR over wait list at initial follow-up. One single study (van Emmerik et al., 2008)showed a significant difference for structured writingtherapy over wait list (N = 45; SMD −0.97 CI −1.59,−0.35; GRADE very low) but there was no differencewhen compared against psychoeducation only (Bugget al., 2009) in another single study. Another singlestudy (Cernvall et al., 2015) showed a significant dif-ference for internet-based guided self-help over waitlist (N = 58; SMD −0.66 CI −1.19, −0.13: GRADEvery low). Findings for cognitive therapy and EMDRwere judged as clinically important. No significantdifferences were found between telephone basedCBT-T and wait list or, from single studies of beha-vioural activation (Wagner et al., 2007) and internet-based virtual reality therapy over wait list (Freedman,n.d.). No difference was found between computerizedneurobehavioral training and a reading-based controlcondition (Ben-Zion et al., 2018). We founda significant effect for collaborative care over waitlist at 3–6 months post-trauma but there was noeffect at 1 month or 7–12 months. These effectswere not judged clinically important. In head tohead comparisons we found no difference betweenCBT-T and self-help or trauma focused CBT andcognitive therapy.
3.1.3. Studies offering intervention to individualswith a diagnosis of acute stress disorder or PTSDFourteen studies (Bryant et al., 1998, 1999, 2003, 2005,2008; Echeburua et al., 1996; Ehlers et al., 2003; Nixon,2012; Nixon et al., 2016; Öst et al., n.d.; Shalev et al.,2012; Sijbrandij et al., 2007; van Emmerik et al., 2008;Wagner et al., 2007) offered interventions to individualswith a diagnosis of acute stress disorder or PTSD,within three months of the traumatic event.Statistically significant differences were found in favourof CBT-T over a wait list control group and supportivecounselling post treatment. Follow-up data wereincomplete but statistically significant differences werepresent at some follow-up time points. There was alsoa significant difference in favour of cognitive therapyover waitlist. There was no difference in head to headcomparison between CBT-T and cognitive therapy.
3.2. Methodological quality of included studies
Risk of bias judgements for individual studies areshown in Table S2 (see online supplement). Thirty-sixstudies adequately described a method of allocationjudged to make no bias possible. Five studies were
considered to be at high risk of bias. Reporting ofadequate concealment procedures was present in 25studies, with six studies considered to be at high riskof bias. Adequate blinding of the assessor of outcomemeasures was present in 42 studies, with 4 studiesconsidered to be at high risk. Incomplete outcomedata was considered low risk in 26 studies, witha further 22 studies judged to be at high risk of bias.Twelve studies, all published since 2010, were judgedlow risk for selective reporting. The majority of otherstudies were of unclear risk, with three studies beingjudged at high risk. Forty studies were judged at highrisk for other bias. Reasons for possible other biasincluded author affiliation with one of the interventionsbeing tested, small sample size, use of measures withinadequate validation, non-manualized interventionand poor treatment adherence. No risk of bias wasindicated in only eight studies. There were insufficientstudies in any of the meta-analyses to allow us to inves-tigate for potential publication bias by preparing funnelplots.
To determine the impact of quality on outcome weundertook a sensitivity analysis for allocation conceal-ment. Four studies with low risk of bias for allocationconcealment evaluating CBT-T versus waitlist wereincluded in a sensitivity analysis. We compared theeffect size and confidence intervals from this analysiswith that of the full analysis to identify possible differ-ences. There was little differences to the estimated effectsize (N = 367, SMD −0.61 CI −1.05, −0.17) from that ofthe original analysis (N = 746, SMD −0.63 CI −0.93,−0.32). We were unable to repeat this sensitivity analy-sis for CBT-T versus supportive counselling as no studywas rated low risk of bias for allocation concealment.
4. Discussion
4.1. Main findings
There was little evidence that most multiple sessionintervention aimed at everyone, irrespective of theirsymptoms, following a traumatic event were effective.Where there was evidence of significant effects, theseeffects were judged as not being clinically importanton our primary outcome measure.
CBT-T, cognitive therapy without exposure, EMDR,structured writing therapy and internet-based guidedself-help all did significantly better than waitlist/usualcare at reducing traumatic stress symptoms in indivi-duals who were symptomatic at entry into the study.Findings for CBT-T, EMDR and cognitive therapywithout exposure were judged as clinically important.CBT-T was the most frequently evaluated approach butEMDR showed the largest effects with positive findingsfrom four small studies. Findings in relation to struc-tured writing therapy and internet-based guided self-help were from single small studies. CBT-Twas the only

approach to be thoroughly evaluated against an activecontrol, with evidence of significant and clinicallyimportant effects in relation to supportive counselling.Only CBT-T and cognitive therapy were evaluated forindividuals who were diagnosed with acute stress dis-order or PTSD and the magnitude of effect was largerfor these individuals. Evidence of the benefits of CBT-Tfor symptomatic individuals who did not meet fulldiagnostic criteria for these conditions was weaker.Although intervention in many of the positive trialsincluded in this review began more than a month afterthe trauma, there was evidence of the benefit of bothCBT-T and EMDR being offered within 2–4 weeksfrom a number of trials (Bryant et al., 1998, 1999,2003, 2005, 2008; Jarero et al., 2011, 2015), suggestingthat it is appropriate to offer early intervention, whenindicated within this acute phase. With the exception ofone study evaluating cognitive therapy based on theEhlers & Clarke model (Ehlers et al., 2003), the majorityof positive trials of CBT-T were based on adapted ver-sions of prolonged exposure. Several well-controlledstudies evaluated a collaborative/stepped care approachfor individuals with traumatic stress symptoms begin-ning within three months of a traumatic event. In meta-analysis there was evidence of an effect at 3–6 months;findings were not judged clinically important. TheGRADE ratings for most meta-analyses was low tovery low suggesting that further research is very likelyto have an important impact on confidence in theestimate of effect and is likely to change the estimate,for findings rated low and findings should be consid-ered uncertain for findings rated very low. There wasconsiderable variability in the timing and collection ofmedium and long-term follow-up data which made itdifficult to draw firm conclusions about the mainte-nance of effects over time. Although there was someinconsistent evidence of long-term benefit for CBT-T.
4.2. Heterogeneity
There was evidence of both clinical and statisticalheterogeneity in the included studies. There weresignificant differences in the clinical populationsacross the included studies, especially with regardsto the nature of trauma exposure and the psychiatricand physical severity of symptoms on entry into thestudies. Of note, participants in some studies hadexperienced serious and life threatening medical con-ditions associated with a chronic illness and it is likelythat intervention outcomes in these studies would beinfluenced by the degree and pace of physical recov-ery and enduring health problems (e.g. Cox et al.,2018; Irvine et al., 2011; Jensen et al., 2016; Joneset al., 2010). Studies also differed in the methodolo-gies that they used, for example with regard tosources of recruitment and inclusion and exclusioncriteria.
Although all the trials attempted to reduce trau-matic stress symptoms, the nature of the interven-tions and target populations were diverse. This waspartially dealt with by separating interventions intopredetermined groups for studies offering interven-tion to individuals with traumatic stress symptomswithin three months of a traumatic event and studiesoffering intervention to individuals with a diagnosisof acute stress disorder or PTSD, although someinterventions did not fit with these pre-plannedgroups and this resulted in some unplanned categor-izations. We attempted to group studies in a clinicallymeaningful way with regards to the intervention andthe clinical populations included but recognize thatthis is not empirically based and would have contrib-uted to heterogeneity. This should be borne in mindwhen interpreting our findings (Borenstein, Hedges,Higgins, & Rothstein, 2009). Some interventions andpopulations were so dissimilar that it was meaning-less to group them at all, particularly for studiesevaluating interventions aimed at any individual,regardless of symptoms.
As in our previous review (Roberts et al., 2009),there were more studies evaluating CBT-T than otherinterventions. Most CBT-T studies were based ona prolonged exposure paradigm, but the specificCBT-T interventions varied in their use of imaginalexposure, in-vivo exposure and cognitive techniques.Two studies were based on a cognitive processingtherapy paradigm (Nixon, 2012; Nixon et al., 2016)and showed no effect when compared against sup-portive counselling. The total number of hours ofintervention provided varied from around twohours to around 16 hours. A post hoc sub-groupanalysis suggested the effects were larger for studiesoffering more sessions of CBT-T. However, the lar-gest treatment effect that we observed was for briefEMDR which at 2–4½ hours were amongst the short-est interventions that were included.
4.3. Methodological quality
The overall quality of the studies was varied. Using theCochrane risk of bias criteria, the proportion of studiesdescribing appropriate randomization, allocation con-cealment and blinding of assessors was higher than inour previous review. It is possible that other includedstudies also used appropriate randomization and allo-cation concealment procedures but reporting of theseprocedures was sometimes limited. The proportion ofstudies with low risk for incomplete outcome data waslow (43%), suggesting that many studies had difficul-ties with retention. Pre-registration of trial protocolswas an emerging issue at the time of our previousreview and none of the studies previously includedprovided a pre-publication protocol. Only a third ofthe newly included studies provided pre-registered
EUROPEAN JOURNAL OF PSYCHOTRAUMATOLOGY 19
study protocols and reported outcomes consistent withthese protocols. Few studies were free of other biases.These biases included author affiliation with one of theinterventions being tested, small sample size, use ofmeasures with inadequate validation, non-manualizedintervention and poor treatment adherence.
Many of the included studies had some metho-dological limitations. However, a sensitivity analysisof higher quality studies based on allocation con-cealment made little difference to the estimatedeffect of CBT-T. This suggests that study qualitydid not have a major effect in elevating apparentefficacy in this key comparison; although we couldnot undertake similar sensitivity analyses in othersmaller comparisons. There is evidence that smallerstudies can exaggerate intervention effects as theytend not to be conducted with the same methodo-logical rigour as larger trials (Higgins & Green,2011). Many of the trials in this review weresmall and this needs to be borne in mind whenconsidering the large effects of some of our find-ings. For example, the large effect in favour ofEMDR over waiting list was a result of 4 trialswith a total of 84 participants.
Four studies evaluated a collaborative/stepped careapproach (O’Donnell et al., 2012; Zatzick et al., 2004,2013, 2015). The specific collaborative care modelsdiffered across these studies, with intervention poten-tially ongoing to 12 months in some trials.Intervention effects in one smaller study (O’Donnellet al., 2012) were noticeably larger than for the otherstudies. This study differed from the other studies inthat participants were screened for elevated symp-toms on two occasions which meant that only parti-cipants who demonstrated high symptom severitywere randomized and then offered a menu of inter-ventions. The other studies allocated patients at anearlier time point and it is likely that some patientswould have experienced natural recovery. Whilsteffects across these studies was small, it has beenargued that collaborative care based approaches canhave a larger population impact than early interven-tions such as CBT-T, when intervention reach istaken into account (Giummarra et al., 2018; Zatzick,Koepsell, & Rivara, 2009).
There was only very limited reporting of adverseevents. Where adverse events were reported, thiswas mainly in trials where there was a high riskof mortality in included participants, resulting fromchronic illnesses (e.g. Irvine et al., 2011-Jones et al.,2010). We did not see evidence of significant dif-ferences in rates of dropout between interventionand control conditions, which continues to suggestthat adverse effects were not common. Despite ourprevious recommendation there was an absence oftolerability assessment, evaluating the acceptabilityof interventions, in new studies. We were unable to
investigate for publication bias. Many of the studiesreported in this review did report null results andwe enquired about non-published studies that hadregistered a study protocol. However, we cannotexclude the possibility that some of our findingsmay have been influenced by some non-reportingof negative findings.
4.4. Implications for practice
Consistent with our previous review, the currentfindings suggest that psychological interventionoffered to all individuals exposed to a traumaticevent irrespective of their symptoms cannot berecommended for routine use following traumaticevents. Several interventions – CBT-T, cognitive ther-apy without exposure, EMDR, structured writingtherapy, and internet-based guided self-help – pro-vided evidence of efficacy in reducing traumatic stresssymptoms, when targeted at symptomatic individuals.Evidence was strongest for CBT-T and for those whofulfilled the diagnostic criteria for acute stress disor-der or PTSD. We believe that this evidence is nowsufficiently strong to recommend the provision ofCBT-T, cognitive therapy or brief EMDR to indivi-duals who are symptomatic following exposure toa traumatic event, as was recommended in the recentISTSS PTSD Treatment Guidelines (InternationalSociety for Traumatic Stress Studies, 2018).However, we note that the National Institution forHealth and Care Excellence had access to the sameevidence base but only felt able to recommend CBT-T (National Institute for Health and Care Excellence,2018). We also note that positive studies were mainlythose including victims of accidental physical injury,such as industrial accidents and motor vehicle acci-dents; physical assault/violent crime; and terrorism.Only one small positive trial was undertaken follow-ing a natural disaster (Jarero et al., 2011). We did notidentify any positive studies that were carried outwith military personnel and studies conducted mainlyor solely with victims of rape and sexual assault werenot positive (Echeburua et al., 1996; Foa et al., 2006).This needs to be borne in mind when considering thegeneralizability of these findings.
Whilst no intervention aimed at all individualsexposed to a traumatic event provided clinicallyimportant findings for a reduction in traumaticsymptoms, small significant differences wereobserved for brief CBT based dyadic therapy, self-guided internet-based intervention and intensivecare diaries at 3–6 months. Given that many indivi-duals experience improvement in traumatic stresssymptoms without the need for intervention, it ispossible that that these interventions may demon-strate a greater effect if targeted at symptomatic indi-viduals. This should be examined further.
20 N. P. ROBERTS ET AL.
Findings from this review provide a strengtheningcase for early routine detection and assessment ofindividuals exposed to traumatic events and the pro-vision of early psychological intervention whenneeded, although optimal models of care requirefurther exploration. This is consistent with recentwork which suggests that early structured clinicianbased PTSD assessment using the ClinicianAdministered PTSD Scale can predict the likelihoodof developing long-term PTSD with a high degree ofaccuracy, across a number of different cultures(Shalev et al., 2019). Arguably, routine use of detec-tion-based approaches would help to reduce the inci-dence of chronic disorders and associated secondaryproblems discussed earlier (McFarlane, 2010). Self-guided (Mouthaan et al., 2013) and guided self-help(Cernvall et al., 2015) potentially offer a flexible andcost-effective means of increasing availability of inter-vention and should be investigated further.
This review did not focus on the use of pharma-cological early interventions. Other work that wehave undertaken for the ISTSS TreatmentGuidelines suggests that the evidence for such inter-ventions is currently very limited (Astill-Wright et al.,in press; International Society for Traumatic StressStudies, 2018). However, we recognize that medica-tion may still have a role in holistic patient care, whenindicated, following trauma exposure.
4.5. Implications for research
Several interventions included in this review showedpromising outcomes but have not been thoroughlyevaluated in well-designed RCTs, with long-termfollow-up. EMDR, cognitive therapy and structuredwriting therapy all require further evaluation andmay benefit from head to head comparison withan evaluated CBT-T based intervention. A numberof other interventions included in this review, suchas behavioural activation (Wagner et al., 2007), havealso not been adequately investigated and wouldbenefit from further investigation. Optimal lengthof early intervention should also be exploredfurther, given our finding that effects were largerfor 12 or more sessions of CBT-T. Future reviewsshould consider whether the literature is sufficientlydeveloped to evaluate CBT-T based interventions bytreatment model. New technologies have the poten-tial to increase the range of options and modes ofdelivery of early psychological interventions. Weincluded several studies investigating theseapproaches in this review (e.g. Ben-Zion et al.,2018; Freedman, n.d.). Development and evaluationof these approaches are in their infancy but theypotentially offer new ways of preventing and ameli-orating early symptoms. A further limitation of thisreview is that we only focused on the prevention
and early treatment of PTSD. Future studies andreviews should also focus on the prevention ofother common mental health problems such asdepression and anxiety disorders following fromtrauma.
