Self-concept, Behavioural Attributions, and Self-awareness in Adolescents with Autism Spectrum Disorder: A Mixed-methods Approach

Although a modest body of literature has emerged to investigate the experiences of youth with Autism Spectrum Disorder (ASD), there is a need to better understand their experiences to guide developmentally appropriate interventions and supports. This exploratory mixed-methods project included two studies aimed at gathering information about the self-perceptions and lived experiences of adolescents with ASD. In study 1, 27 adolescents (ages 13-18) completed measures to examine their self-concept and self-perceived competence, self-awareness of ASD characteristics and behaviours, and the types of behavioural attributions and stigmatizing beliefs they ascribe to their problematic behaviours. Two comparison groups (adolescents with Attention Deficit Hyperactivity Disorder and typically developing adolescents) were used for self-concept and behavioural attribution comparisons. Study 2 comprised a smaller sub-set of 13 participants who participated in interviews designed to capture how ASD is perceived and experienced by those living with this disorder. Study 1 results suggested that adolescents with ASD have some awareness of the social, behavioural and adaptive challenges associated with their diagnosis and, as a group, hold some self-perceptions of competence and behavioural attributions that are different from those of adolescents without ASD. In Study 2, interviews were analyzed thematically to capture how adolescents talk about their diagnosis and psychosocial experiences, and how this may impact their self-concept and self-image. Four major categories emerged: (1) self-awareness and understanding of ASD; (2) psychosocial stress; (3) social-ecological factors; and (4) sources of support. Together, these results provide insights about how they perceive themselves and their diagnosis and some of the individual, family, and school factors related to their self-perceptions and self-awareness. Results from both studies converge to provide support for a systems approach to understanding the interactions between adolescents, families, peers, school, community, and greater society when undertaking individual assessments of needs and treatment planning for ASD. Findings from the studies are discussed with respect to the positive and negative effects of awareness and knowledge about one’s diagnosis on self-perceptions and psychological adaptation. This research has important implications for clinical and educational interventions that address the unique needs and strengths of adolescents with ASD to promote positive developmental outcomes.Ph
