Assessing Peer-Related Impairments Linked to Adolescent Social Anxiety: Strategic Selection of Informants Optimizes Prediction of Clinically Relevant Domains.

Socially anxious adolescents commonly experience impaired interpersonal functioning with unfamiliar, same-age peers. Yet, we lack short screening tools for assessing peer-related impairments. Recent work revealed that a parent-reported, three-item screening tool produced scores that uniquely related to social anxiety concerns. However, this tool ought to go beyond linking impairments to service needs (i.e., social anxiety symptoms). This tool should also inform the goals of services, in particular by linking impairments to key domains relevant to therapeutically addressing adolescents' anxiety-related needs, such as social skills when interacting with unfamiliar peers. This requires an assessment approach that involves strategic selection of informants who vary in their expertise for observing anxiety-related needs, as well as the therapeutic goals for addressing anxiety-related impairments (e.g., social skills within peer interactions). We leveraged parents' reports to link impairments to social anxiety-related needs. To link impairments to social skills, we leveraged informants (i.e., unfamiliar untrained observers [UUOs]) who observed adolescents within tasks designed to simulate interactions with same-age, unfamiliar peers. We tested this approach using a mixed-clinical/community sample of 134 adolescents, ages 14- to 15 years old. We leveraged multi-informant survey reports to assess adolescent social anxiety, and trained independent observers rated adolescents' social skills within unfamiliar peer interactions. Parents' reports performed best when distinguishing adolescents on referral status and predicting survey-reported social anxiety, whereas only UUOs' reports predicted independent observers' social skills ratings. These findings inform the strategic selection of informants for assessing impairments that commonly prompt the need for adolescents to access mental health services for social anxiety.

When Adolescents Experience Co-Occurring Social Anxiety and ADHD Symptoms: Links With Social Skills When Interacting With Unfamiliar Peer Confederates.

Adolescents with elevated social anxiety commonly experience peer-related impairments - particularly with same-age, unfamiliar peers - stemming from their avoidant behaviors. Yet, peer-related impairments are not unique to social anxiety. For example, adolescents who experience social anxiety may also experience symptoms of attention deficit/hyperactivity disorder (ADHD), which also increase risk for peer-related impairments. Relative to social anxiety, peer-related impairments linked to ADHD symptoms more likely stem from hyperactivity (i.e., approach behaviors). These distinct pathways point to adolescents with elevated social anxiety and ADHD symptoms (i.e., social anxiety + ADHD) experiencing particularly high peer-related impairments, which commonly manifest as behavioral displays of low social skills when interacting with unfamiliar peers. We tested this notion in a mixed-clinical/community sample of 134 14- to 15-year-old adolescents and their parents. Adolescents participated in a series of social interaction tasks designed to simulate how adolescents interact with same-age, unfamiliar peers. Trained observers independently rated adolescents on observed social skills within these interactions. Both parents and adolescents completed parallel surveys of social anxiety and ADHD symptoms, which we used to identify social anxiety + ADHD adolescents as well as other combinations of social anxiety and ADHD symptoms (i.e., neither, elevated on one but not the other). Adolescents with social anxiety + ADHD displayed significantly lower social skills, relative to all other groups. Among adolescents, social anxiety + ADHD may have a compounding effect on social skills. As such, therapists working with social anxiety + ADHD adolescents should probe for peer-related impairments and factors implicated in the development and maintenance of these impairments.
