Pragmatic Language Impairment
• Many children with a variety of communication disorders have disrupted use of language or pragmatics
• PLI - Where pragmatics is disproportionately disrupted compared to other aspects of language (such as syntax) development– Bishop 2000
Communication characteristics
• May be talkative• Turn-taking and topic maintenance problems• Information management problems• Inappropriate questioning• Comprehension difficulties• Disorganised narratives• Poor at making inferences• Persistent subtle language impairment into middle
childhood and beyond– Rapin & Allen 1987, Bishop & Adams 1989, Adams 2001
PLI interventions
• Pragmatic communication needs are increasingly part of caseload as more children with ASD are identified
• Recognition of negative consequences of on mental health and social relationships (Whitehouse et al 2009)
• Importance of communication skills in quality of life and well-being
PLI interventions
• Amount and nature of typical provision not known
• Weak evidence base • Currently no guidelines to suggest which
method is preferred for a specific individual’s needs
• Choice of communication intervention may be similar across HFA/PLI groups
• No randomised controlled trials
Evidence for PLI interventions
• Rich clinical expertise literature on broader issues of social communication and conversational disability (Brinton & Fujiki 1995, 2005; Timler, Olswang et al 2005)
• Positive outcomes in case studies of social communication (Adams, 2001; Olswang, Coggins & Timler, 2001; Timler, Olswang & Coggins, 2005)
• Positive effects on conversational skills and some language test scores after intensive therapy in a case-series study (Adams et al, 2006)

The Social Communication Intervention Programme (SCIP)
A randomised control trial of intervention for children with pragmatic language impairment
Catherine Adams and Elaine Lockton
Funded by the Nuffield Foundation
Aim
• Ascertain the effectiveness of an intensive social communication therapy (SCIP), compared to treatment-as-usual, for children who have PLI
– On standardised language assessment functioning
– On functional pragmatic ability and broader social communication as rated by parents and teachers
Participants
Referred from SLT caseloads
• 6 – 11 years old
• Pragmatic communication impairment observed by the child’s SLT
• Attending mainstream primary education provision and identified as having Special Educational Needs/Additional Support Needs
• Receiving regular, ongoing attention from SLT services
• No diagnosis of frank autism• No severe difficulties in emotional
development, behaviour needs, unintelligibility, or hearing loss
• Score ≤ 58 on the General Communication Composite of the Children’s Communication Checklist
• Score ≥ 5th centile on the Ravens Coloured Progressive Matrices
Outline
• Pragmatic language impairment (PLI)
• The Social Communication Intervention Programme (SCIP) trial
• Interventions
• Outcomes
• Conclusions and way forward for complex intervention studies
SCIP intervention
• Complex intervention– Multiple observations– Variable outcomes– Individualisation in treatment delivery
• Manual of intervention– Assessment findings mapped to aspects and goals of
intervention in the SCIP manual– Systematic procedure to allow for prioritisation of
therapy goals identified by the mapping process
SCIP intervention framework
Social communication
social understanding
pragmatics language
processing
Social Understanding and Social Interaction
• Aimed at enhancing understanding of social communication conventions and behaviours, mediated through language – Understanding social context
– Understanding emotions
– Developing and understanding flexibility
– Understanding thoughts and intentions
– Understanding friendships
Language Processing
• Focused on enhancing complex language skills (such as narrative) in order to support social communication– Word-finding and semantics
– Narrative construction
– Understanding idiomatic language
– Understanding of text and complex sentences
– Comprehension monitoring
Pragmatics
• Focused on building understanding and application of pragmatic behaviours and rules in a metacognitive context– Conversation skills
– Understanding information requirements
– Turn taking conventions
– Topic management
– Discourse style
Sabotaging turn-taking
• Consolidate rules/cues• Child can identify, demonstrate and repair• In games, stories, conversation
• Developing heightened self-awareness and self-monitoring skills
• Awareness of the mismatch between habitual social interaction behaviours and conventionally expected behaviours
• Intensive individualised practice
Sabotaging listening skills
The child takes a turn to show that they know what fidgeting is and that you can't listen and fidget at the same time
Is this puppet a good listener?The SLT uses the puppet to show the child that it is harder to listen to the story when the puppet is fidgeting
Individualisation
• Teacher main concerns
– “finds difficulty in staying on task - LSA consistently by side”
– “in whole group teaching - lots of visual prompts needed for good sitting/listening/looking”
Individualisation
• Parents main concerns
– “Friendships and learning social rules”
– “Fixed routines - set aisles at the supermarket”
– “Found it very difficult to cope if he couldn’t stop by the fish counter”
SCIP intervention
• Intensive, reflective and highly individualised• Provides explicit explanations of social
conventions, social behaviours and the vocabulary of interaction
• Support for language comprehension (language scaffolding)
• Close consultation with parents, teachers and support staff for generalisation and suitability of targets as new skills and awareness emerge
SCIP intervention
• Up to three, one-hour therapy sessions per week (up to a maximum of 20 sessions)
• Delivered in school by specialist therapist or trained assistant
• One-to-one sessions, provision of whole class and home based activities
• Parent/teacher/LSA attendance and input solicited throughout
Skills, training and supervision
• Specialist therapists– Extensive specialist knowledge
– Responsible for case management and intervention planning
• Assistants– Intensive and specialised training in pragmatic
communication needs• Principles of intervention - reinforcing targeted vocabulary,
differentiation, using visual supports for learning, managing pace, personalising the intervention to the child
• Therapy methods - modelling, role play, sabotage
• Observation and video recordings used to inform training needs
Treatment-as-usual
• As provided by their local SLT services
• Continued to receive LSA support– Limited direct intervention addressing communication
skills• Delivered by speech-language practitioners or support workers
– Indirect interventions• Typically advice and training on communication for
education/support staff/parents
• Strategies for language support in the classroom and for modifications to the environment (such as use of visual cues)

Standardised language assessments
• Receptive and expressive language
CELF- 4 Core Language Standard Score (CLSS)
• Measure of ability to interpret, remember and tell a pictured narrative
• Initial telling of the story (ERRNI-I)
• Story recall (ERRNI-R)
• Comprehension (ERRNI-C)
Expression, Reception and Recall of Narrative Instrument (ERRNI)
Targeted Observation of Pragmatics in Children’s Conversation (TOPICC)
• Derived, a priori, from the CCC-2
• Autism-type communication problems scale (CCC-2 AUT) identified as a control for bias
Pragmatics rating scale (CCC-2 PRAG)
• Language Skills (PRO-LS)
• Social Communication (PRO-SC)
• Social Situations (PRO-SS)
• Peer Relationships (PRO-PR)
Parent reported outcome (PRO)
• Child’s behaviour in typical classroom situations - starting or completing a task, problem-solving skills, asking for help, working in a group etc
Teacher reported classroom learning skills (TRO-CLS)
Parent/teacher reported measures
Parent reported outcomes T2
• Language skills– “He is asking lots of questions and is putting things in the
correct context. He is more confident and willing to participate where he used to be silent”
• Social communication– “He is finding it easier to wait his turn to speak and will at least
say “excuse me” before butting in! He is definitely following conversations and will chip in if something catches his interest”
– “He still switches off instantly if the topic is of no interest”
Parent reported outcomes T2
• Social situations– “He seems more able to communicate as an equal. There isn’t
as much silence around the table or on car journeys! He is expressing his needs more appropriately”
– “He still disengages himself if he is out of his depth or disinterested”
• Peer relationships– “His relationships have been strengthened. Other children
want him around rather than just wanting to mother him. He can take them or leave them depending on his mood”
Parent reported outcomes T2
• Main concerns now
– “Our concerns are the same but we are thrilled with the progress made in a short space of time”
– “There has certainly been a step change in our child although many communication difficulties remain”
Parent reported outcomes T3
• Language skills– “He will now sometimes initiate conversation with others. He will
enquire more e.g. has asked if his friend has had a nice Christmas” – “He is asking what new words mean all the time and will then try to
use the word”
• Social communication– “He still struggles to take turns. He will say “excuse me” when he
wants to interrupt but still doesn’t see why he then has to wait his turn”
– “The majority of his communication is on a needs only basis about his particular interest”
– “He will not share what he has done at school that day etc”
Parent reported outcomes T3
• Social situations– “He wants to involve himself socially but doesn’t know how
e.g. if the others are playing tig, he doesn’t know how to get himself included. He is equally happy sometimes to disengage himself and let it all just happen around him”
• Peer relationships– “He shows more kindness especially to other children in
distress”– “He has expressed missing another child who has gone to
another school”
Parent reported outcomes T3
• Main concerns now– “Meaningful friendships- this will become more of an
issue as high school looms when he will need to initiate conversations to fit in”
– “Asking for help/expressing displeasure. He is displaying some aggressive behaviour if he is not getting his own way. This is easier for him than wading through tricky language to get his message across”
– “Social rules. Knowing what will help him fit in. Instinctively recognising appropriateness”
Teacher reported outcomes
• “Improved incredibly!- asking questions, more responsive in whole class situations, becoming more independent”
• “Able to listen better even if not being targeted personally”

• Outcomes

Conclusions
• Increased emphasis on importance of patient reported outcomes
• Changes meaningful to those living and working with the children daily
• Central to current aspirations of delivering services which are designed around the family
How and why is SCIP having an effect?
• Difficult to attribute intervention effects to the specific content of SCIP rather than increased specialist attention
• Fair comparison with the care that would have been received were the trial not to have taken place
• Potential for future exploration of mediators• Also moderators – for which individuals is
SCIP preferred choice?
Implications for future complex intervention studies
• Unlikely to be uniform outcome effects across participants
• Outcomes at the levels of activity and participation
• Specific to an individual’s unique context• Novel measures such as differentiated,
individualised criteria for change may need to be adopted
