Evidence Base Update for Measures of Social Skills and Social Competence in Clinical Samples of Youth.

Social skills and social competence are key transdiagnostic processes in developmental psychopathology and are the focus of an array of clinical interventions. In this Evidence Base Update, we evaluated the psychometric properties of measures of social skills and social competence used with clinical samples of children and adolescents. A systematic literature search yielded eight widely used measures of social skills and one measure of social competence. Applying the criteria identified by Youngstrom et al. (2017), we found that, with some exceptions, these measures had adequate to excellent norms, internal consistency, and test-retest reliability. There was at least adequate evidence of construct validity and treatment sensitivity in clinical samples for nearly all measures assessed. Many of the scales included items assessing constructs other than social skills and competence (e.g., emotion regulation). Development of updated tools to assess youth's effectiveness in key interpersonal situations, including those occurring online, may yield clinical dividends.
