Client characteristics and early working alliance development: A person-centered research approach.

Objective: Certain client characteristics are associated with early working alliance difficulties in psychotherapy. However, there is limited quantitative evidence on whether combinations of these characteristics (e.g., intersectional identities, prior treatment experiences) are related to alliance development. The present study leveraged a person-centered research approach to examine profiles of early alliance development and differences in the latent class structure of client characteristics among alliance development profiles.

Method: Individual psychotherapy clients (N = 2,579) rated the working alliance for their first four sessions and self-reported demographics, treatment history, and psychological distress. Therapists provided their assessment of clients' primary presenting concerns at baseline.

Results: Latent profile analysis revealed three profiles of working alliance development: high and stable, moderate and increasing, and low and stable. Follow-up person-centered analyses (multigroup confirmatory latent class analysis) indicated that clients in the alliance profiles differed in their combinations of clinical and demographic characteristics. For example, women of color with high baseline distress and a history of prior psychotherapy were over-represented in the low and stable alliance profile.

Conclusion: These results are consistent with recommendations to holistically consider how clients' characteristics and experiences shape psychotherapy processes. Results also highlight the utility of person-centered quantitative methods in psychotherapy research.
