The development of the Broaching Assessment Scale: A client-rated measure of therapists' broaching behaviour in clinical counselling.

Objective: Addressing ethnic-cultural topics during the process of psychotherapy, i.e. broaching, is considered highly important for ethnic minority clients who consult mental health care services. Surprisingly little is known, however, about clients' perception of a therapist's broaching qualities, and how clients' mental construction of broaching translates into behavioural broaching acts a therapist may display.

Method: Based on previous work and nine in-depth interviews with ethnic minority clients, a client-rated measure of therapists' broaching behaviour was developed and psychometrically evaluated in two samples. Sample 1 (N = 252 UK ethnic minority clients) was used to empirically delineate the factor structure of an initial item set. Participants were then resolicited to complete a revised item pool.

Results: The empirical structure resulted in a final 25-item broaching instrument with five subscales probing into therapists' broaching behaviour. This Broaching Assessment Scale (BrAS) was validated in Sample 2 (N = 239 US ethnic minority clients). Strict measurement invariance of the factor structure was observed across the two samples and distinctive correlational patterns with therapeutic process measures were found.

Conclusion: The BrAS provides new insights on how sensitivity to ethnic-cultural topics can be targeted along its concrete features, and is a promising tool for conceptualizing culturally sensitive mental healthcare assessment.
