A scoping review of current approaches to strengths-based transition practices for autistic adolescents

This review aimed to map the literature surrounding strengths-based approaches in studies with autistic adolescents focusing on adult transition outcomes, by describing the active ingredients of interventions and the properties of assessment tools. Relevant databases were searched for articles surrounding strengths-based practices, which met the following criteria: (a) written in English, (b) published since 1990, and (c) involving adolescent participants with a diagnosis of autism spectrum disorder. Data extraction included sample, aim, intervention description, outcome measures, and results. Data were synthesised using a descriptive approach and thematic analysis was conducted to identify active ingredients, practice strategies, outcomes, and assessment properties. Overall, 35 articles met the inclusion criteria, including 26 studies evaluating strengths-based interventions and 9 articles relating to general transition outcomes. Five types of interventions were classified according to their active components: transition planning, employment preparation and training, technology programmes, peer mentoring, and cognitive skills training. The best practice themes highlighted the importance of leveraging each individual's interests and skills, developing individualised processes, and accommodating participant's needs through a holistic approach. Analysis of the outcome measures highlighted a gap in standardised strengths-based assessments, but uncovered primary outcome themes of self-determination, social skills, confidence, and work-related skills.Lay abstractThis review explores research on strengths-based approaches for autistic adolescents, particularly focusing on outcomes related to transitioning into adulthood. The goal was to identify and describe the key components of strengths-based interventions and assessment tools. The review looked at studies published since 1990 that involved adolescents with a diagnosis of autism spectrum disorder and included a variety of approaches aimed at promoting positive adult outcomes. After analysing 35 relevant articles, the review categorised five types of interventions based on their key components: transition planning, employment preparation, technology programmes, peer mentoring, and cognitive skills training. The review also identified fewer strengths-based measures than expected, with many studies employing custom measures. This points to a gap in reliable strengths assessments for autistic adolescents, which would be useful in transition planning and improving self-image. Despite the lack of standardised tools, the review highlighted several common strengths-based outcomes, such as improvements in self-determination, social skills, confidence, and work-related skills.
