Abstract

Introduction

Social competence refers to a person's ability to interact positively and effectively with others across different contexts.1,2 Social participation is the act of being involved or engaged with others.3 The ability to develop and maintain meaningful relationships with others has a long-term protective impact on an individual's psychological well-being, achievement in school and work, community participation levels, law-abiding behavior, and avoidance of substance abuse.4,5 Adolescence is a developmental stage of increasing social expectations and personal initiation of strategies to gain acceptance and maintain friendships.6,7

Adolescents with congenital or acquired diagnoses, such as brain injury and fetal alcohol spectrum disorders (FASD), can struggle to make and keep friends.8-10 Social dysfunction is frequently reported clinically in these populations as having a lasting negative impact, with early research detailing varying prevalence estimates of social competence difficulties.10-13 Prevalence rates for youth with traumatic brain injury (TBI) differ according to specific study samples and choice of measurement tools. A systematic review of 28 studies confirmed an elevated risk of social dysfunction for youth with TBI, despite methodological weaknesses in the literature.11 In a sample of 113 children (74 TBI; 39 typically developing), 23% of youth in the TBI group demonstrated social impairments two years post injury in the absence of pre-injury difficulties.14 In a sample of 87 children aged eight to 13 years old, 47% percent of children with severe TBI had a mutual friend in their classroom compared to almost 88% of children with orthopedic injury or a mild to moderate TBI.15 Studies of prevalence in youth with cerebral palsy (CP) are also emerging, indicating difficulties with social functioning in 33% to 45% of children.10,13 In contrast, another study demonstrated similar developmental curves of social interaction between typically developing peers and children with CP with no intellectual impairment.16 In this study, lower levels of ability to socially interact and wide variation in results were revealed for individuals with CP and an intellectual impairment.16 Most youth with FASD are reported to experience difficulties with social competence, although exact prevalence data in the literature is limited.9,17-19

Group social skills interventions (GSSIs) aim to increase social knowledge and skills in adjusting behavior in social interactions, and usually encompass a combination of didactic teaching, modeling, role play, and homework tasks to encourage generalization of skills to everyday situations.20 They vary in intensity, duration, whether an intervention manual is used, and if a parent group is included. Investigation of the efficacy of GSSIs has primarily reported on evidence in the autism spectrum disorder (ASD) population and, to a lesser extent, the attention-deficit hyperactivity disorder (ADHD) population as difficulty with social skills is a core feature of the diagnosis in these populations.21,22 Systematic reviews investigating the efficacy of GSSIs for youth with ASD indicates a medium effect on improving social competence with effect sizes ranging from 0.47 to 0.56.21,23,24 The efficacy of GSSIs in improving social competence in children and youth with ADHD has been investigated through two systematic reviews revealing the methodological limitations in the literature, and making it difficult to conclude whether GSSIs are effective in increasing social competence.22,25

With limited research into the efficacy of GSSIs in populations with acquired and congenital diagnoses other than ASD and ADHD, there is insufficient information available to guide clinicians in their clinical practice. This review will examine the evidence for GSSIs with an available intervention manual that may be suitable for use in clinical trials and ultimately clinical practice for youth with difficulties with social functioning related to a diagnosis such as acquired brain injury (ABI), CP, or FASD.

A preliminary search of PROSPERO, PubMed, the Cochrane Database of Systematic Reviews, and the JBI Database of Systematic Reviews and Implementation Reports was conducted on GSSIs for adolescents with acquired, congenital, and developmental disabilities. Current and in-progress systematic reviews of GSSIs focus specifically on ASD21,24 and ADHD,22,25 and do not include other acquired and congenital disabilities. Given the social difficulties experienced by youth with ABI, CP, and FASD, and inadequate empirical evidence for treatment, this review will evaluate GSSIs across acquired and congenital diagnosis groups and offer evidence to support treatment choice in different populations of youth.

Review questions

  • i) Do GSSIs, with a supporting intervention manual, increase social knowledge, social competence, or social participation in adolescents with acquired, congenital, or developmental disabilities?
  • ii) What are the features of individual GSSIs?

Inclusion criteria

Participants

This review will consider studies that include adolescents (aged 11 to 17 years) with an acquired, developmental, or congenital disability. As this review will focus on adolescents of high school age who have different needs to children attending primary school, where the included age in studies extends beyond the 11-to-17 age range, a mean age of no less than 11 and no higher than 17 will be used to ensure findings are relevant for high school students. Studies of adolescents with a primary mental health disorder will be excluded.

Interventions

This review will consider studies that evaluate GSSIs with the primary aim of the intervention to improve social knowledge, social competence, or social participation. Group interventions that have an available manual will be included. Interventions will have a component of face-to-face delivery, while other intervention components may include education (via additional appointments, written information sheets, internet-based platforms, or additional parent groups) and individualization of the group program (via additional appointments, phone- or internet-based contact). Interventions may be run by any health professional or youth worker and delivered in community, research, or hospital settings. Given that the focus of this systematic review is to inform health practitioners of interventions they could deliver in clinical settings, GSSIs that are only delivered in schools will be excluded. No limits will be placed on the duration, frequency, or intensity of interventions.

Comparators

This review will consider studies that compare the intervention to either another intervention or no intervention.

Outcomes

This review will consider studies that evaluate social competence as a primary outcome. Social competence will be measured by a tool suitable to detect change after a clinical intervention, including but not limited to the Social Skills Improvement System-Rating Scale (SSIS-RS) and the previous version, the Social Skills Rating Scale (SSRS); the social subscale of the Adaptive Behavior Assessment System (ABAS), the Vinelands Adaptive Behavior Scale, or the Child Behavior Checklist and the Social Responsiveness Scale (SRS). Secondary outcomes may include social participation, with measures including but not limited to behavior rating scales such as the Child and Adolescent Scale of Participation (CASP), or social knowledge, often measured by a tool developed by authors of an intervention to test retention of knowledge. Naturalistic observation scales, interviews, goal setting, or sociometric techniques of measuring social competence, social participation, or social functioning will be included if they have used a validated tool or a reproducible rating scale.

Types of studies

Preliminary searching revealed a considerable number of existing randomized controlled trials testing the efficacy of GSSIs to improve social competence and social participation in youth with acquired and congenital disability. Given the reduced risk of bias in evaluating the efficacy of interventions tested using a randomized control trial study design, this review will only include randomized controlled trials.26 Studies published in English and from database inception to the present will be included.

Methods

The proposed systematic review will be conducted in accordance with JBI methodology for systematic reviews of effectiveness.27 This protocol has been registered in PROSPERO: CRD42020158189.

Search strategy

The search strategy aims to locate both published and unpublished studies. An initial limited search of PubMed and PsycINFO was undertaken to identify articles on the topic. The text words contained in the titles and abstracts of relevant articles, and the index terms used to describe the articles were used to develop a full search strategy (see Appendix I) with assistance from a medical librarian. The search strategy, including all identified keywords and index terms, will be adapted for each included information source.

Information sources

The databases to be searched include: PubMed, CINAHL (via EBSCOhost), Embase, CENTRAL (via the Cochrane Library), PsycINFO (via EBSCOhost), and Web of Science. Sources of unpublished studies and gray literature to be searched include Clinical Trials Registry (ClinicalTrials.gov and WHO-International Clinical Trials Registry Platform), Google Scholar, and ProQuest Dissertations and Theses. The reference lists of all studies selected for critical appraisal will be searched for additional studies.

Study selection

Following the search, all identified citations will be collated and uploaded into EndNote X9 (Clarivate Analytics, PA, USA) and duplicates removed. Titles and abstracts will then be screened by two independent reviewers for assessment against the inclusion criteria for the review. Potentially relevant studies will be retrieved in full and assessed in detail against the inclusion criteria by two independent reviewers for the full text screening stage. Reasons for exclusion of full text studies that do not meet the inclusion criteria will be recorded and reported in the systematic review. Disagreements that arise between the reviewers at each stage of the study selection process will be resolved through discussion or with a third reviewer. The results of the search will be reported in full in the final systematic review and presented in a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flow diagram.28

Assessment of methodological quality

Eligible studies will be critically appraised by two independent reviewers at the study level for methodological quality in the review using the Cochrane risk-of-bias tool (RoB 2) for randomized trials.29 Random allocation, deviation from intended interventions, management of missing data, outcome measurement, and data analysis will be evaluated. Authors of papers will be contacted to request missing or additional data for clarification, where required. Any disagreements that arise between the reviewers will be resolved through discussion or via consultation with a third reviewer. The results of the critical appraisal will be reported in narrative form and in a table. In this review, a randomized control trial design is considered essential for methodological rigor, with studies not meeting this quality threshold excluded.

Data extraction

Data will be extracted from studies included in the review by two independent reviewers using the standardized JBI data extraction tool available in the JBI System for the Unified Management, Assessment and Review of Information (JBI SUMARI; JBI, Adelaide, Australia). The data extracted will include specific details about the populations, study methods, interventions, adverse events, and outcomes of significance to the review objective. Any disagreements that arise between the reviewers will be resolved through discussion or with a third reviewer. Authors of papers will be contacted to request missing or additional data, where required.

Data synthesis

Studies will, where possible, be pooled with statistical meta-analysis using RevMan Version 5.3.5 (Copenhagen: The Nordic Cochrane Centre, Cochrane), with separate meta-analyses performed according to timing of the outcome measures (eg, immediately post, three- to six-months follow-up, six- to 12-months follow-up, and 12+ months follow-up). Effect sizes will be expressed as weighted (or standardized) final post-intervention mean differences (for continuous data) and their 95% confidence intervals. Heterogeneity will be assessed statistically using the standard chi-squared and I2 tests. Statistical analyses will be performed using a random effects model.30 Subgroup analyses will be conducted where there is sufficient data to investigate the efficacy of GSSIs in different populations (eg, acquired versus congenital conditions), types of programs, and methods of implementation (eg, presence of a concurrent parent group). Sensitivity analyses will be conducted to test decisions made regarding risk of bias. Where statistical pooling is not possible, the findings will be presented in narrative form, including tables and figures to aid in data interpretation, where appropriate. A funnel plot will be generated to assess publication bias if there are 10 or more studies included in a meta-analysis. Statistical tests for funnel plot asymmetry will be performed where appropriate.

Assessing certainty in the findings

The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach for grading the certainty of evidence will be followed31 and a Summary of Findings (SoF) will be created using GRADEpro (McMaster University, ON, Canada). The SoF will present the following information where appropriate: absolute risks for the treatment and control, estimates of relative risk, and a ranking of the quality of the evidence based on the risk of bias, directness, heterogeneity, precision, and risk of publication bias of the review results. The outcomes reported in the SoF will be social knowledge, social competence, and social participation.
