The Effects of Human Caring Theory-Based Interventions on Women's Mental Health: A Systematic Review

Background/Objectives: This systematic review aims to synthesize existing evidence on the impact of nursing interventions based on Watson's Theory of Human Caring (THC) on women's mental health and to provide an evidence-based framework for clinical practice. Methods: The review followed the PRISMA guidelines and was registered in the PROSPERO database (Registration No: CRD420251111577). A comprehensive literature search was conducted across databases, including PubMed, CINAHL, and Google Scholar. Ten studies (nine randomized controlled trials and one quasi-experimental study), involving 869 participants, met the eligibility criteria. Data were analyzed using a narrative synthesis approach due to methodological and clinical heterogeneity. Results: A total of 10 studies involving 894 women met the inclusion criteria. Geographically, nine studies were conducted in Türkiye and one in Iran. The included studies spanned various clinical contexts directly associated with significant mental health challenges for women, including medical abortion, infertility, gynecological oncology, and the postpartum period. The synthesized findings demonstrated that nursing interventions based on Watson's Human Caring Theory led to statistically significant reductions in anxiety, depression, stress, postpartum depression risk, and infertility-related distress. Furthermore, these caritas-based frameworks significantly enhanced positive psychological assets, including self-efficacy, hope, meaning in life, prenatal attachment, and social support perception. Conclusions: Watson's Theory of Human Caring provides a transformative framework for women's health nursing that extends beyond symptom management to strengthen the individual's internal resources and spiritual integrity. Integrating this theory into clinical protocols and nursing curricula is essential for humanizing care and protecting women's mental health during challenging life transitions, particularly within the examined sociocultural contexts.
