Evidence supporting the effectiveness of the PEERS® social skills intervention for adolescents with autism spectrum disorder is relatively strong. Less is known about whether the duration of the program impacts participant outcomes. The current study compared outcomes of participants randomly assigned to participate in an accelerated version of PEERS that met twice weekly for 7 weeks (n = 11) or the traditional PEERS program that met once weekly for 14 weeks (n = 10). The accelerated PEERS group demonstrated improvements consistent with previous research on the program, and treatment response did not differ significantly between the accelerated PEERS and traditional PEERS groups. Together, findings provide preliminary evidence that PEERS is effective when administered as a 7-week program.

This study compared immediate and 4-month outcomes among adolescents with autism spectrum disorder randomly assigned to the PEERS curriculum (n = 10), a peer mediated PEERS curriculum (n = 12), or a delayed treatment control group (n = 12). Findings suggest a modest advantage in social skills knowledge and social functioning for participants in the peer-mediated PEERS curriculum relative to Traditional PEERS, and gains in social skills knowledge, social functioning, and reductions in loneliness were maintained in one or both treatment groups at a 4-month follow-up. Typically developing peer mentors (n = 16) showed improvements in social skills knowledge and marginal improvements in autism knowledge and loneliness. Future research with a larger sample and objective outcome measures is needed.

Research suggests that toddlers with no language delay (NLD) should have better outcomes than those with language delay (LD). However, the predictive utility of language milestones relative to co-varying factors such as age at diagnosis, IQ, and ASD symptomatology is unclear. This study compared school-aged children with ASD and NLD (n = 59) to a well-matched group with ASD and LD (n = 59). The LD group was diagnosed at younger ages and their historical ASD symptoms were more severe than the NLD group. The groups were similar in current ASD symptoms and adaptive functioning at school age. Language milestones were correlated with adaptive functioning, but IQ and social symptoms of ASD were stronger predictors of functioning at school age. Therefore, language milestones may not be the best indicators of prognosis for children who are diagnosed after toddlerhood.

There is a dearth of research regarding adaptive functioning during the transition to adulthood in autism spectrum disorder (ASD). Profiles on the Vineland Adaptive Behavior Scales, Second Edition were examined by age and intellectual ability in 75 participants with ASD (16-58 years). Results extend previous reports of a cognitive advantage over adaptive functioning in children by demonstrating a similar pattern in an older sample. Daily living skills were a relative strength compared to communication and socialization in adults, but not adolescents. In general, highest subdomain scores were observed in writing skills and lowest scores were observed in interpersonal skills. Regardless of cognitive ability, all standard scores were well below average, indicating a need for lifelong intervention that targets adaptive functioning.

Profiles of performance on the Stanford Binet Intelligence Scales (SB5) and Vineland Adaptive Behavior Scales (VABS) were examined in 73 children and adolescents with autism spectrum disorder. SB5 cognitive profiles were observed to be similar between participants with and without early language delay, but different between participants with and without intellectual disability. With few exceptions, the distribution and cognitive profiles of participants with specific nonverbal IQ-verbal IQ and abbreviated IQ-full scale IQ discrepancy patterns paralleled previous reports. A cognitive functioning advantage over adaptive functioning was observed to be strongest in participants without intellectual disability and older participants. The previously reported VABS "autism profile" was not observed. Current findings clarify previous research and will inform the diagnostic process and treatment planning.
