Sustaining community employment is a challenge for adults with autism spectrum disorders, especially for those who have co-occurring intellectual disability, but factors contributing to this employment outcome have not been fully evaluated. This study utilized longitudinal data to explore the impact of contextual influences, family factors, and individual characteristics on sustained employment over approximately 18 months ( N = 105). Very few adults with autism spectrum disorder and intellectual disability achieved sustained employment (14.

The Social Responsiveness Scale [SRS; Constantino & Gruber, 2005] is a widely-used measure of autism symptoms, but its application for the study of adults with autism spectrum disorders has not been fully evaluated. Using a factor structure consistent with The Diagnostic and Statistical Manual of Mental Disorders (5th ed., DSM-V) criteria for autism spectrum disorder [Frazier et al.

The present investigation explored long-term relationships of behavioral symptoms of adolescents and adults with developmental disabilities with the mental health of their mothers. Fragile X premutation carrier mothers of an adolescent or adult child with fragile X syndrome (n = 95), and mothers of a grown child with autism (n = 213) were included. Behavioral symptoms at Time 1 were hypothesized to predict maternal depressive symptoms at Time 3 via maternal executive dysfunction at Time 2.

Research related to supports for adults with autism spectrum disorder (ASD) is under-developed. As an example, system and service development to support successful transition to adulthood and meaningful vocation for adults has received relatively little research scrutiny until recently, with practitioners and program developers lacking evidenceinformed approaches guiding service delivery. A Special Interest Group (SIG) was convened at the International Meeting for Autism Research in May 2014 and May 2015, with a focus on transitional and vocational issues in ASD.

This study aims to extend the definition of quality of life (QoL) for adults with autism spectrum disorder (ASD, n = 180, ages 23-60) by: (1) characterizing the heterogeneity of normative outcomes (employment, independent living, social engagement) and objective QoL (physical health, neighborhood quality, family contact, mental health issues); and (2) identifying predictors of positive normative outcomes and good objective QoL. Findings of an exploratory latent class analysis identified three groups of adults with ASD-Greater Dependence, Good Physical and Mental Health, and Greater Independence. Findings indicate that better daily living skills, better executive function, and more maternal warmth are associated with assignment to better outcome groups.

The present study examined trajectories of adaptive behavior, behavior problems, psychological symptoms, and autism symptoms in adolescents and adults with fragile X syndrome (n = 147) over a three-year period. Adaptive behavior significantly increased over time, particularly for adolescents, and the severity of behavior problems decreased over time. Family environmental factors predicted phenotypic variables net of gender, intellectual disability status, and medication use.

This study examined the perceptions of adulthood among 31 high school students with autism spectrum disorder (ASD). We had two research aims: (1) to report students' postsecondary expectations in terms of school, work, friendships and living arrangement and (2) to describe how our sample defined adulthood. To better compare our sample's criteria of adulthood to the criteria traditionally endorsed in secondary schools, we used a directed content analysis approach.

We examined factors related to subjective quality of life (QoL) of adults with autism spectrum disorder (ASD) aged 25-55 (n = 60), using the World Health Organization Quality of Life measure (WHOQOL-BREF). We used three different assessment methods: adult self-report, maternal proxy-report, and maternal report. Reliability analysis showed that adults with ASD rated their own QoL reliably.

In the present study, we jointly employ and integrate variable- and person-centered approaches to identify groups of individuals with autism spectrum disorders (ASD) who have similar profiles of change over a period of 10 years across three critical domains of functioning: maladaptive behaviors, autism symptoms, and daily living skills. Two distinct developmental profiles were identified. Above and beyond demographic and individual characteristics, aspects of both the educational context (level of inclusion) and the family context (maternal positivity) were found to predict the likelihood of following a positive pattern of change.

Little is known about outcomes for individuals with autism spectrum disorders (ASD) into adulthood. Several characteristics of individuals with ASD predict long-term outcomes, and the family environment may also play a role. The present study uses a prospective, longitudinal design to describe and predict trajectories of autism symptoms and maladaptive behaviors over 8.

The transition of a student out of high school and into the adult world can be a stressful time for many families of high school students. This major life transition can be particularly challenging for students with ASD and their families. In this paper we first discuss the roles of families in the transition process for their son or daughter with ASD.

This article reports the findings from a longitudinal program of research examining the bidirectional influences of the family environment on the behavioral phenotype of autism, and describes a newly developed family psychoeducation program, titled Transitioning Together, designed to reduce family stress, address behavior problems, and improve the overall quality of life of adolescents with autism and their families. A case study is presented that illustrates how Transitioning Together helps reduce family stress and improve the overall quality of the family environment. The article concludes with a discussion of directions for future research on best practices in working with families of children, adolescents, and adults with autism.

Background: Activity limitations are an important and useful dimension of disability, but there are few validated measures of activity limitations for adolescents and adults with developmental disabilities.

Objective/hypothesis: To describe the development of the Waisman Activities of Daily Living (W-ADL) Scale for adolescents and adults with developmental disabilities, and systematically evaluate its measurement properties according to an established set of criteria.

Methods: The W-ADL was administered among four longitudinally studied groups of adolescents and adults with developmental disabilities: 406 with autism; 147 with fragile-X syndrome; 169 with Down syndrome; and 292 with intellectual disability of other or unknown origin.

Although an increasing number of individuals with autism spectrum disorders are entering adulthood, currently there are few evidence-based programs for individuals later in the life course. In this paper we present an overview of recent research on outcomes for adolescents and adults with ASD and highlight the role of the family for individuals with ASD during the transition to adulthood. We also discuss multi-family group psychoeducation as a promising model for use with individuals with ASD who are transitioning to adulthood.

Research shows that Latinos are less likely to be diagnosed with autism than their non-Latino counterparts. One factor that may contribute to these differences is that autism diagnostic instruments have not been adapted for the Latino population. The present study compared scores from the Autism Diagnostic Interview-Revised for two groups: 48 Latino adolescents and adults with autism and a matched sample of 96 non-Latino Whites.

The present study explored the behavioral profile of individuals with fragile X syndrome during adolescence and adulthood. Individuals with both fragile X syndrome and autism (n  =  30) were compared with (a) individuals diagnosed with fragile X syndrome (but not autism; n  =  106) and (b) individuals diagnosed with autism (but not fragile X syndrome; n  =  135) on measures of autism symptoms, adaptive functioning, behavior problems, and psychological symptoms. Results indicated that individuals dually diagnosed with fragile X syndrome and autism displayed greater communication and social reciprocity impairments than individuals with fragile X syndrome only.

Health symptoms of mothers of adolescents and adults with fragile X syndrome (FXS; n = 112) were compared to a nationally-representative sample of mothers of similarly-aged children without disabilities (n = 230) as well as to a sample of mothers of adolescents and adults with autism spectrum disorders (ASD; n = 96). Health symptoms experienced in the previous 24 h were recorded during 8 consecutive days of a daily diary study. Both mothers of a son or daughter with FXS and mothers of a son or daughter with ASD had a higher proportion of days with headaches, backaches, muscle soreness, fatigue, and hot flashes than mothers of children without disabilities.

The present study investigated the impact of social support on the psychological well-being of mothers of adolescents and adults with ASD (n = 269). Quantity of support (number of social network members) as well as valence of support (positive support and negative support) were assessed using a modified version of the "convoy model" developed by Antonucci and Akiyama (1987). Having a larger social network was associated with improvements in maternal well-being over an 18-month period.

In a previous study, high levels of maternal criticism predicted increased behavior problems in adolescents and adults with autism spectrum disorders (ASD) over an 18-month period (Greenberg, Seltzer, Hong, & Orsmond, 2006). The current investigation followed these families over a period of 7 years to examine the longitudinal course of criticism and behavior problems, to assess the association between their trajectories, and to determine the degree to which change in each of these factors predicted levels of criticism and behavior problems at the end of the study period. A sample of 118 mothers coresiding with their adolescent and adult children with ASD provided open-ended narratives about their children and reported on the children's behavior problems at 4 waves.

The present study examined the detection of early developmental delays of high-risk infants by first-time mothers in a community sample of families (N = 451). About half of the mothers were adolescents at time of childbirth, and two thirds reported household incomes below $20,000 annually. Children were assessed at 12 and 24 months of age on standardized measures of cognitive, language, adaptive, and socioemotional development.

Using daily diary methods, mothers of adolescents and adults with ASD (n = 86) were contrasted with a nationally representative comparison group of mothers of similarly-aged unaffected children (n = 171) with respect to the diurnal rhythm of cortisol. Mothers of adolescents and adults with ASD were found to have significantly lower levels of cortisol throughout the day. Within the ASD sample, the son or daughter's history of behavior problems interacted with daily behavior problems to predict the morning rise of the mother's cortisol.

In the present study, 96 co-residing mothers of adolescents and adults with an autism spectrum disorder (ASD) participated in an 8-day diary study and reported on their daily experiences. In comparison with a nationally representative sample of mothers of children without disabilities, mothers of adolescent and adult children with ASD spent significantly more time providing childcare and doing chores, and less time in leisure activities. Fatigue, arguments, avoided arguments, and stressful events were also more common among mothers of individuals with ASD.
