Examining culturally based variables associated with ethnicity: influences on credibility perceptions of empirically supported interventions.

Treatment rationales for 2 widely used and empirically supported interventions, cognitive therapy (CT) and time-limited dynamic psychotherapy (TLDP), were examined for their perceived credibility among 136 Asian American college students. This study conducted a comprehensive analysis of culturally based variables (often assumed to underlie ethnicity) and their related effects on credibility perceptions. Variables assessed included cultural identity, self-construals, values, and mental health beliefs. Participants were randomly assigned to read either a CT or TLDP treatment rationale for depression and then rated the credibility of the interventions. Results indicated that cultural identity and self-construals moderated credibility ratings across CT and TLDP rationales. Findings underscore the importance of moving beyond ethnic group analyses to the examination of specific culturally based variables.
