Given the importance of client characteristics and preferences, and therapist expertise to evidence-based practice in psychology, the current study sought to contribute to the literature concerning the role of values in psychotherapy. Personal values of clients and trainee therapists in 29 dyads were examined for relationships between client and therapist values and associations with working alliance and outcomes. Although previous literature in this area has suggested that successful therapy is characterized by an increase in similarity of client and therapist values, the current study did not replicate this finding. However, client perceptions of therapist values were found to be important to working alliance and outcome. Findings are discussed in terms of suggestions for future research as well as implications for clinical practice, including the importance of discussing expectations and preferences with clients.
