The self-stigma (i.e., shame) associated with psychotherapy is a prominent barrier to seeking psychological help, but less is known about its effects after treatment begins. Evidence suggests that self-stigma may interfere with the formation of the therapeutic alliance, but no studies have examined this throughout the course of psychotherapy. Self-stigma's erosion of the alliance may be most pronounced when clients experience heightened psychological distress, but this also has not been examined. Therefore, the present study addresses these omissions among 37 clients who completed at least three therapy sessions for research credit. Participants completed measures of self-stigma and past-week symptoms of distress before each session and ratings of the working alliance after. Predictor variables were disaggregated into betweenperson (time-invariant or average levels) and within-person (time-variant or session-by-session changes) components to enable investigation of for whom (and under what conditions) self-stigma was associated with the therapeutic alliance. Results indicated that higher levels of self-stigma (between and within persons) predicted a worse alliance. When examined as an interaction effect alongside distress in a multilevel moderation model, higher between-person ratings of self-stigma predicted a weaker therapistclient alliance across levels (M ± 1 SD) of within-person distress. Notably, its effects became more pronounced as symptoms of distress increased, indicating a period in which clients are simultaneously most likely to need help yet least likely to feel allied with their therapist. Findings highlight the importance for therapists to simultaneously monitor and consider both average and session-by-session fluctuations in selfstigma and distress to develop and maintain the working alliance.
Clinical Impact StatementQuestion: (a) Does the self-stigma of seeking psychotherapy, when considered at between-(i.e., timeinvariant, or average levels) and within-person levels (i.e., time-variant, or session-by-session fluctuations), interfere with the therapy process by damaging the therapist-client working alliance? (b) Is this relationship moderated by fluctuations in past-week symptoms of psychological distress? Findings: (a) Heightened self-stigma (between and within persons) predicts lower ratings of the alliance. (b) There is a cross-level moderation effect: higher between-person ratings of self-stigma predict a weaker alliance across levels (M ± 1 SD) of within-person distress; its adverse effects are exacerbated as, session-by-session, clients experience heightened symptomatology. Meaning: The effects of self-stigma interfere with the working alliance and do not disappear "at the therapy door." To develop and maintain the alliance, it appears important for therapists to consider self-stigma and distress as both trait-and state-like components. Next Steps: Future research is needed to examine the interactional effects between self-stigma and psychological distress among diverse clinical population...
