DSM-IV Diagnostic Criteria for PTSD
Exposure to a traumatic event in which the person: experienced, witnessed, or was confronted by death or serious
injury to self or others AND responded with intense fear, helplessness, or horror
Symptoms appear in 3 symptom clusters: re-experiencing,
avoidance/numbing, hyperarousal last for > 1 month cause clinically significant distress or impairment in functioning

DSM-IV Diagnostic Criteria for PTSD
Reexperiencing Persistent re-experiencing of 1 of the following:
recurrent distressing recollections of event recurrent distressing dreams of event acting or feeling event was recurring psychological distress at cues resembling event physiological reactivity to cues resembling event

DSM-IV Diagnostic Criteria for PTSD
Avoidance and Numbing Avoidance of stimuli and numbing of general
responsiveness indicated by 3 of the following: avoid thoughts, feelings, or conversations avoid activities, places, or people inability to recall part of trauma interest in activities estrangement from others restricted range of affect sense of foreshortened future

DSM-IV Diagnostic Criteria for PTSD
Hyperarousal Persistent symptoms of increased arousal 2:
difficulty sleeping irritability or outbursts of anger difficulty concentrating hypervigilance exaggerated startle response

DSM 5 PTSD Criteria
As of May 2013, the DSM 5 has contained slightly different PTSD diagnostic criteria
Symptoms are mostly the same The 3 clusters of DSM-IV symptoms will be divided into 4
clusters in DSM-5: intrusion symptoms, avoidance symptoms, arousal/reactivity symptoms and negative mood and cognitions.
Criterion A2 (requiring fear, helplessness or horror happen right after the trauma) will be removed.
Based on the proposed DSM-5 criteria, the prevalence of PTSD will be similar to what it is currently in DSM-IV.

Incidence of PTSD
69% of civilians report experiencing a traumatic event (Norris, 1992; Resnick et al., 1993)
Affects more than 10 million American children or adults (National Center for PTSD, 2001)
Lifetime prevalence in the U.S. is 6.8%, making it the third most common anxiety disorder (Kessler et al., 2005)
Females are at approximately 2x greater risk than males

Consequences of PTSD
Negative impact on affect regulation, attention, cognition, interpersonal relationships and neuroendocrinology (Hart et al.,1995; Maughan & Cicchetti, 2002; Putnam et al., 1997)
Increased risk for: Physical health problems (Pacella, Hruska, &

46.4% of people with PTSD meet criteria for one or more SUDs (Pietrzak, Goldstein, Southwick, & Grant, 2011)
Comorbidity rates of substance abuse/dependence in PTSD are high (up to 43%) (Breslau, Davis, & Schultz, 2003; Deering, Glover, Ready, Edelman, & Alarcon, 1996; Friedman, 1991; Friedman & Yehuda, 1995; Kessler, Sonnega, Bromet, Hughes, & Nelson, 1995).
PTSD rates range from 30-50% in substance abusers (Dansky, Roitzsch, Brady, & Saladin, 1997; Mills, Lynskey, Teesson, Ross, & Darke, 2005)
253 Australian detox inpatients (Dore et al., 2012) 80% experienced > 1 trauma 45% screened for PTSD
SUD-PTSD Comorbidity
![Page 16: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/16.jpg)
PTSD-SUD is associated with significant impairment
More severe alcohol problems (McFall, MacKay, & Donovan, 1992)
Greater utilization of addiction treatment services (Brown, Stout, & Mueller, 1999) Higher relapse rates, poorer treatment outcomes (Jacobsen et al., 2001; Read et al.,
2004)
More severe PTSD symptoms (Hien, Campbell, Ruglass, Hu, & Killeen, 2011; Saladin, Brady, Dansky, & Kilpatrick, 1995)
![Page 17: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/17.jpg)
PTSD-SUD is associated with significant impairment, cont’d
Less successful PTSD treatment (Perconte & Giger, 1991)
Greater medical, social and employment costs than either disorder alone (Neuman et al., 2012; Brady et al., 2004; Brown et al., 1994)
Psychiatric comorbidity in SUD patients can serve as a barrier to successful SUD engagement and treatment at every stage of the process
![Page 18: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/18.jpg)
Theories of Comorbidity: SUD and PTSD
The self-medication hypothesisThe high risk hypothesisThe susceptibility hypothesisThe substance-induced anxiety
enhancement hypothesis
The shared vulnerability hypothesis
Stewart & Conrod, 2008; Hruska and Delahanty, in press
![Page 19: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/19.jpg)
Comorbidity Theory: Self-Medication Hypothesis
PTSD temporally precedes SUD and leads to the development of substance use problems as the individual attempts to self-medicate the negative affect associated with their trauma symptoms.
![Page 20: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/20.jpg)
Comorbidity Theory: High Risk Hypothesis
Substance use puts one at risk for exposure to traumatic events and subsequently, PTSD. Substance use precedes PTSD.
![Page 21: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/21.jpg)
Comorbidity Theory: Susceptibility Hypothesis
The use of substances increases the likelihood of developing PTSD following a traumatic event. Substance use precedes PTSD.
![Page 22: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/22.jpg)
Comorbidity Theory: Substance-induced anxiety
enhancement hypothesisSUD leads to the development of PTSD
symptoms following trauma because SUDs affect the functioning of the body’s stress response system
![Page 23: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/23.jpg)
Comorbidity Theory: Shared vulnerability hypothesis
PTSD and SUD onset occur near the same time due to a shared vulnerability (genetic/physiological/ underlying risk factors) common to the development of both disorders
![Page 24: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/24.jpg)
Tension Reduction Model
Neuroendocrine, neuroanatomical, and genetic research support the tension reduction model (Hruska & Delahanty, in press)
Trauma or PTSD diagnosis precedes the onset of alcohol or substance abuse (Bremner et al., 1996; Clark & Jacob, 1992; Davidson et al., 1985, 1990)
Having PTSD increased the risk of developing a subsequent SUD, but presence of drug abuse or dependence did not substantially increase risk for developing PTSD (Chilcoat and Breslau, 1998)
PTSD symptoms mediate the relationship between prior trauma and alcohol use in adult women (Epstein, Saunders, Kilpatrick, & Resnick, 1998).
![Page 25: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/25.jpg)
As trauma victims with PTSD may self-medicate with substances to decrease the intensity of PTSD symptoms, decreasing PTSD symptoms through empirically supported therapies may be associated with a decrease in substance use/abuse.
Failure to address underlying PTSD symptoms results in greater SUD relapse rates, further reinforcing the importance of addressing psychopathological barriers to SUD treatment success (Brown et al., 1999)

Intervention: Prolonged Exposure
![Page 27: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/27.jpg)
Prolonged exposure therapy (PE) PE therapy has been found to be effective
in the treatment of PTSD and comorbid symptoms across several controlled studies
Most appropriate form of treatment for PTSD (Ballenger et al., 2000)
PE aims to reduce the fear or anxiety associated with the trauma by encouraging patients to repeatedly confront fear-evoking stimuli (Foa et al., 2007)
![Page 28: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/28.jpg)
PE: Mechanisms
Repeated imaginal exposure facilitates habituation and reduction of anxiety associated with the traumatic memory
By imagining and discussing the traumatic event with a supportive therapist, the patient begins to realize that thinking about the trauma is not dangerous
![Page 29: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/29.jpg)
PE: Mechanisms
Through imaginal exposure to the trauma memory and in vivo exposure to external cues, the patient begins to differentiate the traumatic event from other situations, decreasing generalization of fear responses
Following repeated exposure, the patient achieves a sense of mastery that contradicts the typical view of symptoms reflecting weakness
![Page 30: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/30.jpg)
Prolonged Exposure
Equally efficacious in African-Americans and Whites
Effective in treating victims from a wide range of traumas including war experiences, rape, assault, crime, and samples including victims of a variety of different traumas
Effective in treating individuals who have been multiply traumatized and patients who suffer from complex PTSD
![Page 31: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/31.jpg)
PE compared to other approaches
PE is more effective and efficient than: relaxation training eye movement desensitization and
reprocessing (EMDR) counseling stress inoculation training (SIT) combination therapy involving both PE and
SIT, especially at longer-term follow-up assessments
![Page 32: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/32.jpg)
Prolonged Exposure
10 sessions conducted twice per week for 5 weeks.
Each session lasts between 90-120 minutes. Include education about common reactions
to trauma, breathing retraining, prolonged (repeated) imaginal exposure to trauma memories, repeated in vivo exposure to situations the client is avoiding due to trauma-related fear, and discussion of thoughts and feelings related to exposure exercises.
![Page 33: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/33.jpg)
Session 1
Begins with an overview of the treatment program and a general rationale for exposure. The therapist gathers information focusing on the client’s symptoms, details of the trauma, history of previous trauma, and social and occupational functioning. Breathing retraining is introduced and the client practices breathing techniques. Homework consists of daily breathing exercises, listening to the tape of the session, and reviewing the "Rationale for Treatment" handout.
![Page 34: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/34.jpg)
Session 2
Focuses on education, treatment planning, and development of the in vivo exposure hierarchy. The therapist provides an explanation of PTSD, discusses common reactions to trauma, discusses a rationale for the treatment, and provides a description of each treatment component. The use of Subjective Units of Distress (SU) ratings is explained. A list of avoided situations is compiled and an exposure hierarchy is developed.
![Page 35: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/35.jpg)
Session 3
Reviews the rationale for PE and introduces prolonged imaginal exposure. The client is guided through 60 minutes of imaginal reliving of the focal trauma. The client is instructed to relive the trauma as vividly as possible, and to recount it aloud in the present tense. This procedure is repeated until the exposure period is expended. SU ratings are obtained every 5 minutes and vividness ratings are taken every 10 minutes.
![Page 36: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/36.jpg)
Sessions 4-9
Focus on imaginal exposure for 45-60 minutes, followed by discussion of any thoughts and feelings provoked by the reliving. During imaginal exposure, the therapist asks specific questions to clarify the client's thoughts, feelings, and physical reactions while reliving the trauma to facilitate confrontation with fear-evoking cues. The parts of the scenario that are the most anxiety-producing for the client are identified and emphasized in repeated exposure.
![Page 37: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/37.jpg)
Session 10 (Termination)
Imaginal exposure lasts 30 minutes. The therapist and client review treatment progress and discuss applications of treatment principles to daily life. This discussion will address the potential for temporary increases in PTSD symptoms, and how these can be managed. At this time, the therapist and client will evaluate progress and determine whether additional sessions or referral may be worthwhile.

Using Prolonged Exposure for individuals with PTSD and
Substance Abuse

PE in SUD populations
Initial concern was risk for substance use relapse six male veterans undergoing imaginal flooding
therapy for PTSD, 3 out of 4 of the patients with current or past histories of alcoholism relapsed to alcohol abuse (Pitman et al., 1991)
More recent examinations of the efficacy of PE have not found consistent relationships between substance use and treatment outcome or dropout
![Page 40: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/40.jpg)
PE in SUD populations (Cont,d)
Interventions developed to treat comorbid SUD and PTSD have incorporated imaginal exposure
Exposure therapies have demonstrated efficacy in reducing PTSD severity in SUD-PTSD patients
Patients who have received PE reported fewer cravings than those who did not
We have also demonstrated the efficacy of PE in a study of HIV+ individuals, 60% of whom reported substance use at the start of the protocol

Peach Study (Pacella et al., 2012): Conclusions
Overall, PE was readily accepted by PLWH and was efficacious in reducing symptoms of:
PTSS for HIV and non-HIV related trauma Depressive symptoms
PE was not associated with exacerbation of self-reported substance use (SU). The control group went from an average of 7 instances of SU in the last week at baseline to 2 at post-intervention to 7 at 3-month follow-up, while the PE group went from 3 at baseline to 2 at post-intervention to 4.5 at 3-month follow-up.
PE and control participants did not significantly differ on adherence variables

Studies on Detox Populations
For the first two detox studies… 42.2% (195/462) meet criteria for PTSD
The incidence of trauma is significantly greater in detox than in the general population
On the average, a detox clients experiences seven different types of trauma

Prolonged Exposure and Motivational Interviewing Study
(PE-MI) at Detox• Where: ADM Crisis Center Detox facility
• Purpose: To implement intervention to clients during wait period for substance use treatment
• Intervention: Conduct 9-10 PE sessions with two MI sessions before entering SUD treatment
![Page 55: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/55.jpg)

Detox PE-MI Study, cont’d
• Challenges to PE-MI study• Transportation• Chaotic lifestyles• Lack of means to communicate (cell phone, email, etc.)• Lack of case management
– Needed help obtaining housing, food, clothing etc.– Majority of clients were homeless and didn’t have any
support– Difficult to implement intervention when basic needs aren’t
being met

Prolonged Exposure Treatment Engagement study (PETE)
• Where: Male and female CBCF facilities in Akron, OH
• Purpose: Remove trauma-related psychological barriers to engagement in substance use treatment
• Intervention: Implement 10 sessions of PE to clients prior to beginning their SUD treatment within the facility
![Page 58: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/58.jpg)
PETE study, cont’d
Why is a correctional setting better? Removal of basic barriers to
treatment(i.e. shelter, food, clothing) No need for transportation Have social support within facility Limited access to the outside, allowing
for focus of developing skills to manage stress
Limited wait period to begin substance use treatment

Alternatives for treatment in Community Corrections
Recent Adjustments to Accommodate Felony Drug Offenders
Transitioning clients that would benefit from PE Currently use individual counseling sessions and
active review and check-up with patients to discuss substance abuse and PTSD issues
Potential Adjustments to Accommodate Felony Drug Offenders
Requiring clients who are diagnosed with PTSD to attend at least the first two sessions of PE
Clinical judgment and patient must agree to attend further sessions
If not, other PTSD treatments may be offered such as Seeking Safety
![Page 68: TREATING OFFENDERS WITH SUBSTANCE ABUSE AND POSTTRAUMATIC STRESS DISORDER Douglas L. Delahanty Alec Boros Kent State University Oriana House](https://reader035.vdocuments.us/reader035/viewer/2022070407/56649e405503460f94b31e77/html5/thumbnails/68.jpg)
Alternatives for treatment in Community Corrections
Potential Adjustments: Seeking Safety curriculum help transition clients into PET Developed in early 1990’s
Addresses both trauma/PTSD and substance abuse
25 topics usually given over 12-weeks

Alternatives for treatment in Community Corrections
Advantages of using Seeking Safety: Group and individual Either gender, adults/adolescents Substance abuse/ substance dependence Can be used for clients with trauma history but
meeting PTSD criteria Can be conducted as an open group Lessons can be given in any order
Has QA/CQI tools to be used to measure clinicians adherence to programMore information at www.seekingsafety.org
