Spirituality and religiosity are increasingly recognized as important factors influencing mental health, particularly among women exposed to diverse vulnerabilities such as interpersonal violence, trauma, HIV infection, homelessness, and socioeconomic disadvantage. This systematic review aimed to synthesize evidence on the associations between spiritual or religious resources and mental health outcomes in these populations. A systematic search was conducted in Scopus, PubMed, and Web of Science to identify studies examining the association between spirituality, religiosity, and mental health outcomes in vulnerable women. A total of 28 studies were identified, including cross-sectional, longitudinal, and mixed-methods designs, which measured spirituality and religiosity using validated instruments such as SWBS, DUREL, FACIT-Sp-12, and Brief RCOPE, alongside standardized mental health measures. Narrative synthesis revealed that the majority of studies (n = 15) reported that higher spiritual well-being, intrinsic religiosity, and adaptive religious coping were associated with lower depression, anxiety, and post-traumatic stress, and with higher resilience, quality of life, and post-traumatic growth. These associations appeared to be shaped by contextual factors, including the type and severity of trauma, cultural and religious frameworks, and the lived experiences of the populations studied. Negative associations were primarily linked to negative religious coping (n = 5 studies), rather than religiosity per se. Additional factors that attenuated or reversed the expected positive effects included higher trauma severity or ongoing adversity (n = 4), reactive patterns in which greater psychological distress was associated with increased use of religious coping (n = 3), maladaptive religious beliefs such as interpretations of trauma as divine punishment (n = 2), and cultural or contextual influences (n = 3). Overall, the evidence suggests that spirituality and specific dimensions of religiosity (e.g., intrinsic religiosity, religious coping) can support mental health among vulnerable women, though personal, cultural, and situational factors shape their impact. These findings suggest the potential value of integrating spiritual resources into interventions and the need for further longitudinal and culturally sensitive research.
