Perceived support and relational effects in psychotherapy process constructs.
Recent research has indicated that only a small portion of supportiveness reflects the objective properties of providers. Instead, supportiveness primarily reflects the unique relationships among specific recipients and providers (i.e., relational effects), thus suggesting new approaches to support interventions. The authors investigated the possibility that similar relational effects occur for therapy process constructs (e.g., working alliance). Isolating relational effects in psychotherapy requires that each client receive treatment from more than one therapist during the same period of time. Therefore, we conducted analog studies in which therapy clients and students viewed videos of therapists and then rated expected therapist supportiveness and expected therapy process constructs for each therapist. Two studies indicated very strong relational effects in therapist supportiveness and therapy process constructs. In addition, process constructs were correlated strongly with supportiveness (Study 1) and favorable affect (Study 2) for relational effects specifically. Implications for integrating research on perceived support and therapy process were discussed.
