Teacher- and parent-reported trajectories of maladaptive behaviors among individuals with autism and non-spectrum delays.

People with autism spectrum disorder (ASD) and non-spectrum developmental delays frequently exhibit maladaptive behaviors throughout the lifespan, which can have pervasive effects on quality of life. Maladaptive behaviors have been shown to change over time as a function of various individual-level factors (e.g., cognitive ability), yet research is primarily limited to parent-reported measures. To expand upon this work, the present study aimed to examine trajectories of teacher- and parent-reported maladaptive behaviors (i.e., hyperactivity, irritability, social withdrawal) and to test whether individual-level predictors (e.g., autism features, verbal intelligence quotient) and school-related predictors (e.g., teacher type, student-adult ratio, personal aide, school type) impact these trajectories among 165 individuals with ASD or non-spectrum delays from ages 9 to 18. Multilevel models revealed that, according to both teacher and parent report, participants showed the greatest improvement in hyperactivity, less but still notable improvement in irritability, and stable levels of social withdrawal over time. Higher verbal ability and fewer ASD features, in addition to mainstream school placement, emerged as important individual- and school-related differences associated with fewer maladaptive behaviors over time. The multi-informant perspective and longitudinal design provide novel insight into the manifestations of these maladaptive behaviors across different contexts and across time. Findings highlight the consistency of teacher- and parent-reported trajectories over time and further emphasize the importance of targeting maladaptive behaviors using a multisystem intervention approach in both school and home contexts.

Sibling Influences on Trajectories of Maladaptive Behaviors in Autism.

Siblings play an important role in the behavioral trajectories of individuals with autism spectrum disorder (ASD). While having siblings has been associated with positive outcomes in ASD, including stronger adaptive functioning, social and non-verbal communication, and theory of mind, little is known about the impact of siblings on more negative outcomes, such as maladaptive behaviors. To address this gap, the present longitudinal study tested sibling predictors of trajectories of maladaptive behaviors (e.g., teacher- and parent-reported hyperactivity, irritability, and social withdrawal) from childhood through early adulthood among individuals with ASD and non-spectrum delays. Multilevel models revealed that, while the mere presence of a sibling did not impact maladaptive behavior trajectories apart from teacher-reported hyperactivity, the diagnostic profile of the sibling (e.g., emotional/behavioral disorder, ASD, medical condition) emerged as an important predictor. Specifically, although findings varied across teacher and parent reports, more hyperactivity and irritability across time was identified when the sibling had diagnoses of an emotional/behavioral disorder, ASD, and/or a medical condition. Overall, this study provides novel insight into the broader family-level factors that influence the presentation of maladaptive behaviors across time and across contexts.

A pilot study of PEERS® for Careers: A comprehensive employment-focused social skills intervention for autistic young adults in the United States.

BACKGROUND: Autistic young adults are at elevated risk for poor employment/internship outcomes, despite having many strengths relevant to the workplace. Currently, very few employment interventions for this population comprehensively promote skills development and success across the various stages of employment. AIMS: To address this gap, the current study aimed to test the feasibility, acceptability, and efficacy of a novel college to career intervention program, PEERS® for Careers. METHODS AND PROCEDURES: Twelve autistic young adults (19-30 years old) were enrolled and matched to a career coach. The pilot program consisted of 90-minute sessions delivered twice per week, for 10 weeks, covering content relevant to obtaining, maintaining, and thriving in employment/internship settings. OUTCOMES AND RESULTS: Results indicated that young adults showed a significant improvement in employment-related social skills knowledge, p < .001. Participants also reported significant improvements in their feelings of preparedness for employment over the course of the study, p = .009, with all young adults self-identifying as "somewhat prepared" or "very prepared" post-intervention. Additionally, in only a brief 10-week intervention, a slight increase in participants who secured or maintained internship/employment-related activities was observed. Overall, lesson content and coaching were perceived as helpful. No significant changes were observed in self-reported autism symptomatology. CONCLUSIONS AND IMPLICATIONS: In sum, the PEERS® for Careers program shows promise as a college to career intervention program for autistic young adults. WHAT THIS PAPER ADDS: There is a dearth of evidence-based interventions for autistic young adults, despite significant need for supports to bolster vocational and relational success. This paper is the first to evaluate the PEERS® for Careers intervention in a pilot study by exploring feasibility, acceptability, and efficacy of this novel college to career intervention program, which teaches ecologically valid employment-related skills using a strengths-based approach. Results suggest PEERS® for Careers shows significant potential as a comprehensive intervention to address the multi-faceted needs of autistic individuals in the workplace through didactic lessons, behavioral rehearsals to practice skills, and out of group assignments. Autistic young adult participants reported a high level of satisfaction with the program and lessons surrounding employment-related social skills. They also endorsed increased feelings of internship/employment readiness and increased knowledge of workplace etiquette, with most participants maintaining or securing employment. This study supports PEERS® for Careers as a feasible intervention that likely benefits autistic individuals' vocational outcomes, which emerge as a strong correlate of well-being in adulthood. This work is essential to furthering the development and provision of effective services to meet needs of the autism community.

Influence of siblings on adaptive behavior trajectories in autism spectrum disorder.

LAY ABSTRACT: Siblings have the potential to shape the developmental trajectories of individuals with autism spectrum disorder. Having siblings has been associated with better social communication skills, less severe non-verbal communication deficits, and improved theory of mind abilities in autism spectrum disorder. This study examined the influence of the presence of a sibling, participant's position in the birth order, gender of the closest-age sibling, and gender match of the sibling dyad on the rate of growth in adaptive skills from ages 9 to 26 years among individuals with autism spectrum disorder and individuals with a history of non-spectrum developmental disorders. While all participants showed consistent gains in adaptive skill development as a function of age, there was variability in rates of growth based on sibling constellation group membership. Participants with at least one sibling, regardless of other sibling constellation factors, experienced greater rates of growth in adaptive behavior trajectories from childhood to adulthood than participants with no siblings across both Black and White participants, although differences were magnified in Black participants. Furthermore, among participants with siblings, those with male closest-age siblings and those with gender-matched siblings, irrespective of birth order position, demonstrated the steepest growth patterns in adaptive functioning within their respective groups over the 17-year period. Results suggest that siblings may serve an important role in improving the adaptive functioning trajectories and overall outcomes of individuals with autism spectrum disorder.

The Diagnosis of Autism: From Kanner to DSM-III to DSM-5 and Beyond.

In this paper we review the impact of DSM-III and its successors on the field of autism-both in terms of clinical work and research. We summarize the events leading up to the inclusion of autism as a "new" official diagnostic category in DSM-III, the subsequent revisions of the DSM, and the impact of the official recognition of autism on research. We discuss the uses of categorical vs. dimensional approaches and the continuing tensions around broad vs. narrow views of autism. We also note some areas of current controversy and directions for the future.
