Assessment of the Type A behavior pattern in adolescents

213 adolescents were assessed for the Type A behavior pattern by means of the Adolescent Structured Interview (ASI) and the Bortner Adjective Rating scale (BARS). The concordance of these two measures of Pattern A was examined, as well as the association of each of these measures with independent self-report indices of the major behavioral components of Pattern A (e.g., competitive-achievement striving, aggressiveness-hostility, and time urgency). Although the concordance of the ASI and BARS was low, both measures demonstrated validity in terms of the association between the Type A rating and the indices of the components of Pattern A.
