Why is Spiritual Psychotherapy for Inpatient, Residential, and Inpatient Treatment (SPIRIT) more effective when provided by nonreligious clinicians?

Previous research suggests that patients receiving spiritual psychotherapy may have better outcomes when treatment is provided by nonreligious clinicians, compared to religious clinicians. We examined these effects within a large and clinically heterogeneous sample of patients ( = 1,443) receiving Spiritual Psychotherapy for Inpatient, Residential, and Intensive Treatment (SPIRIT; Rosmarin et al., 2019) by a diverse sample of clinicians ( = 22). In addition to demographics, patients completed a brief measure of their experience in SPIRIT; clinicians completed measures of previous mental health training, previous training in spiritual psychotherapy, and attitudes toward spiritual psychotherapy, and also provided details regarding modalities, clinical interventions, and spiritual interventions utilized at each SPIRIT session. Perceived benefit of SPIRIT was greater when treatment was delivered by non-religious clinicians. Mediating factors on these effects were evaluated using correlations and multiple regression analyses. Of 26 potential explanatory factors, only 4 were significant, all of which related to the therapeutic process. Nonreligious clinicians were more likely to utilize dialectical behavior therapy (DBT), facilitate coping, encourage spiritual coping, and explore the relevance of spirituality to mental health, all of which also predicted better perceived benefit from SPIRIT. All four variables jointly, but not severally, mediated relationships between clinician religion and perceived benefit of SPIRIT. These findings suggest that DBT may be the most effective modality for delivering spiritual psychotherapy to acute patients, particularly in a group setting. Future research should further examine preferences for clinical modalities and techniques among religious and nonreligious clinicians, and effects of such preferences on perceived benefit, in a variety of settings.
