Determining the therapist's contribution in therapist multicultural competence process and outcome.

Efforts to help therapists improve their multicultural competence (MCC) rely on measures that can distinguish between different levels of competence. MCC is often assessed by asking clients to rate their experiences with their therapists. However, differences in client ratings of therapist MCC do not necessarily provide information about the relative performance of therapists and can be influenced by other factors including the client's own characteristics. In this study, we used a repeated measures design of 8,497 observations from 1,458 clients across 35 therapists to clarify the proportion of variability in MCC ratings attributed to the therapist versus the client and better understand the extent that an MCC measure detects therapist differences. Overall, we found that a small amount of variability in MCC ratings was attributed to the therapist (2%) and substantial amount attributed to the client (70%). These findings suggest that our measure of MCC primarily detected differences at the client level versus therapist level, indicating that therapist MCC scores were largely dependent on the client. Clinical implications and recommendations for future MCC research and measurement are discussed. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
