Therapy processes and outcomes of psychological interventions for women diagnosed with gynecological cancers: A test of the generic process model of psychotherapy.

Objective: Little attention has been paid to the role of nonspecific therapy processes in the efficacy of psychological interventions for individuals diagnosed with cancer. The goal of the current study was to examine the three constructs from the generic model of psychotherapy (GMP): therapeutic alliance, therapeutic realizations, and therapeutic openness/involvement in the treatment outcome of women with gynecological cancers attending either a 7-session supportive counseling intervention or a coping and communication skills intervention.

Method: Two hundred and three women completed measures of alliance, realizations, and openness after Intervention Sessions 2, 3, and 6, as well as measures of depressive symptoms after these sessions and 6 months after the pre-intervention assessment (posttreatment).

Results: Consistent with the GMP, in early sessions, therapeutic bond predicted openness in terms of positive affect experienced during sessions, and both aspects of openness (positive and negative affect), in turn, predicted more therapeutic realizations. Therapeutic realizations predicted perceptions of greater session progress, and greater therapeutic bond predicted more therapeutic realizations. When early session GMP variables were used to predict later GMP processes and outcomes and posttreatment outcomes, early therapeutic bond predicted later session therapeutic realizations directly and indirectly via emotional arousal, emotional arousal predicted session progress, session progress predicted lower postsession depressive symptoms, and depressive symptoms as rated after Session 6 predicted depressive symptoms 3 months posttreatment. However, a number of additional associations among GMP processes were found.

Conclusions: Our results suggest that therapy processes played a role in predicting both short- and long-term treatment outcomes.
