Transition to Adulthood for High-Functioning Individuals with Autism Spectrum Disorders

Abstract

Adolescence and young adulthood appear to form the most difficult period in the lives of high-functioning individuals with autism spectrum disorders (ASD;Tantam, 2003).The challenges often faced by those without intellectual disabilities appear to result from the demands of social relationships, academics, employment, and independent living in those with ASD, which may exacerbate core ASD deficits or co-occurring conditions (Barnhill, 2007;Howlin, 2000).The features of these developmental periods, combined with the general challenges with transitions in this population, may explain why the reduction in ASD symptoms that individuals experience throughout life (Seltzer et al., 2003) tend to slow in the transition to adulthood (Taylor & Lounds, 2010).This population appears to be growing despite a shortfall in services and knowledge about these individuals, posing the need for more attention to this area (Barnard et al., 2001;Gerhardt & Lainer, 2011;Shattuck et al., 2011).Adulthood marks a transfer of legal responsibility for individuals with ASD from parental support to self-advocacy.Young adults are often faced with needs to make decisions about their lives, yet they may not fully understand their own unique profile of strengths and weaknesses, or how to advocate for services to meet their needs (Geller & Greenberg, 2010;Townson et al., 2007).In addition, these young adults often feel socially alienated during this period of transition, as though they do not belong or fit in with their peer group (Portway & Johnson, 2003;Ryan & Raisanen, 2008; Simmeborn Fleischer, in press), while sensing others' may be underestimating their competences (Ashby & Causton-Theoharis, 2009).These struggles may not only relate to social deficits, but may also be associated with cognitive, emotional, and sensory information processing deficits (Chamak et al., 2008).For example, sensory overload may compromise the cognitive performance of individuals with ASD or lead to withdrawal or absence of participation from various social situations (Madriaga, 2010).Yet for adults with ASD, quality of life or subjective wellbeing appears positively related to perceived informal support and inversely related to unmet formal support needs.Disability characteristics such as ASD symptoms and IQ appear to be unrelated to subjective wellbeing (Renty & Roeyers, 2006).These findings have implications for the provision of accommodations and formal support for relationships and daytime activities for adults with ASD.Yet services tend to decline for individuals with ASD after they leave high school, which appears related to reduced abatement of ASD symptoms, the frequent absence of daytime activities such as higher education or work, and strains on the mother-child www.intechopen.com
