A comprehensive review of the practice-based evidence for spiritually integrated psychotherapy (SIP) is
necessary in order to catalyze research and training in this important diversity area. In this article, we identify
and synthesize key findings from 35 studies in six key areas: (a) SIPs in trauma treatment, (b) SIPs in treating
eating disorders, (c) SIPs in general psychotherapy, (d) existential concerns as part of SIPs, (e) patients and
therapist attitudes about SIPs, and (f) SIP supervision and training models. Building on this, we propose a
culturally contextual understanding of this diversity area, drawing from the Relational Spirituality Model
(RSM). Finally, we discuss best practices for spiritually responsive clinical care and offer a research
prospectus to strengthen the evidence base for real-world effectiveness.
Clinical Impact Statement
Question: In what ways are clients’spirituality, religion, theology, and/or existential concerns relevant
in real-world mental health treatment? Findings: Clients’spiritual and religious context have important
implications for their symptom alleviation and well-being, and may intersect with other areas of their
identity. Meaning: Therapists should consider spirituality as an important diversity area that may be a
source of strength or struggle for clients. Next Steps: Ongoing research is needed to understand the
nuances of how clients’spirituality is best integrated into psychotherapy with different populations.
Keywords: spirituality, religion, psychotherapy, practice-based evidence

Research suggests that many patients would like to engage spiritual
and/or religious issues as part of their mental health treatment if
confident their providers would be accepting of their values and
perspectives (Harris et al., 2016). Broadening to an inclusive frame-
work of Spiritual, Existential, Religious, and Theological dimensions
of experience (SERT; Sandage, Rupert, et al., 2020), we notice that
despair and hope, emptiness and vitality, mortality and meaning, and
many similar themes are salient in psychotherapy. The capacity to
skillfully adapt treatment to patients’values and practices is an
important aspect of culturally competent clinical practice, yet SERT
experience has historically been neglected, oversimplified, or avoided,
often seen as the purview of religious leaders rather than psychothera-
pists (Sperry, 2012). Some patients may be initially hesitant to discuss
SERT concerns and wait for their therapist to ask, wondering if this is
relevant in a presumed “secular”or “medical”environment (Oxhandler
et al., 2018). Furthermore, patients’SERT perspectives often intersect
with their race, ethnicity, nationality, gender, sexual orientation, and
social location in ways that intensify minority stress and increase
discrimination in healthcare settings. The nuances of intersectionality
can challenge therapists’spiritual and religious competence, and few
clinicians appear to receive adequate clinical training in this diversity
area (Oxhandler & Parrish, 2018;Vieten & Scammell, 2015). Despite
these clinical complexities, a well-established outcome literature has
documented the efficacy of integrating patients’SERT concerns in
randomized controlled treatment settings. In a meta-analysis of 97
experimental and quasi-experimental studies, spiritually integrated
psychotherapies (SIPs) facilitated a greater sense of spiritual well-
being compared to standard approaches and promoted equivalent
symptom reduction (Captari et al., 2018). This body of literature helps
make the case for the clinical legitimacy of SIPs in mental health
treatment and the possibility of enhanced impact on areas of spiritual
functioning that can be important to many patients. Moreover, a
growing body of research shows that patients’psychosocial
