Group-based social skills interventions (GSSIs) are widely used for treating social competence among youth with autism spectrum disorder (ASD), but their efficacy is unclear. Previous meta-analysis of the literature on well-designed trials of GSSIs is limited in size and scope, collapsing across highly heterogeneous sources (parents; youths; teachers; observers; behavioral tasks). The current meta-analysis of randomized control trials (RCTs) was conducted to ascertain overall effectiveness of GSSIs and differences by reporting sources. Nineteen RCTs met inclusion criteria. Results show that overall positive aggregate effects were medium (g = 0.51, p < 0.001). Effects were large for self-report (g = 0.92, p < 0.001), medium for task-based measures (g = 0.58, p < 0.001), small for parent- and observer-report (g = 0.47 and 0.40, respectively, p < 0.001), and nonsignificant for teacher-report (p = 0.11). Moderation analyses of self-report revealed the effect was wholly attributable to youth reporting that they learned about skilled social behaviors (social knowledge; g = 1.15, p < 0.01), but not that they enacted them (social performance; g = 0.28, p = 0.31). Social skills interventions presently appear modestly effective for youth with ASD, but may not generalize to school settings or self-reported social behavior.

Friendship-making is considered a well-established domain of deficit for children with autism spectrum disorders (ASD; American Psychiatric Association, 2013), with this population sometimes described as incapable of making friends. However, the majority of children with ASD indicate a desire for friends, and many report having friends. To what degree, then, do youth with ASD succeed in achieving friendships with peers? If and when they do succeed, by what means do these friendships emerge relative to models of typically developing (TD) youths' friendships? To address these questions, we first meta-analyzed the descriptive friendship literature (peer-reported sociometrics, self-report, parent-report) among school-age boys with ASD. Using random effects models, we found that youth with ASD do make friends according to peers and parents (Hedges's g > 2.84). However, self-reported friendship quality (Hedges's g = -1.09) and parent- and peer-reported quantity (Hedges's g < -0.63) were poorer than TD peers. We consider these findings in light of 2 conceptual frameworks for understanding social deficits in ASD (social cognition and social motivation theory) and in view of a leading model of friendship in TD youth (Hartup & Stevens, 1997). We then present a model that synthesizes these domains through the construct of social information processing speed, and thereby present the first developmental, process-based model of friendship development among youth with ASD.

Supportive school services are a primary service modality for youth with autism spectrum disorder. Autism spectrum disorder, as well as co-occurring psychiatric symptoms and low intellectual abilities, interfere with academic achievement and therefore influence decisions about school services. Therefore, we examined the association of parent, teacher, and clinician ratings of autism spectrum disorder and co-occurring psychiatric symptom severity and intellectual functioning with school services. In total, 283 youth with autism spectrum disorder were assessed with clinical evaluation via the Autism Diagnostic Observation Schedule and parent and teacher versions of the CASI-4R ( Child and Adolescent Symptom Inventory). Full Scale Intelligence Quotient scores were obtained from case records. Clinical and teacher evaluations of autism spectrum disorder severity predicted services and were more strongly associated with school services than parent ratings. Teacher ratings were only associated with common school services (e.g. speech/language therapy, occupational therapy, and/or social skills training) frequency at medium and high levels of clinician-rated autism spectrum disorder severity. Higher IQ and parent-rated externalizing symptoms predicted lower likelihood of receiving school services, whereas internalizing symptoms were not predictive of school services. Autism spectrum disorder symptoms may overshadow externalizing and internalizing symptoms when considering school service supports. Results highlight the importance of evaluating autism spectrum disorder severity via multiple sources, especially in cases of unclear symptom presentation, when examining correlates of school services for youth with autism spectrum disorder.

While social difficulties in autism are well-established, questions remain regarding whether these represent challenges in acquiring or performing such skills, reduced social strengths, or a unique distribution across these domains (i.e., social profile). This study empirically derived social profiles of 211 autistic and non-autistic youth (M age = 13.50; Autistic N = 150; Male N = 151; 85.3% White). Assessments occurred between 2016 and 2020. Results showed that autistic youth exhibit significantly more social acquisition and performance deficits and fewer strengths than nonautistic youth (ds = −.44 to .65). Performance deficits were most-and acquisition deficits least-prominent within autistic profiles, potentially implicating longstanding theoretical models of social difficulties in autism, and supporting new, idiographic approaches for conceptualizing, assessing, and treating social challenges.
