Psychometric Properties of the Turkish Version of the Spiritual Fortitude Scale

Purpose Spiritual fortitude is a vital internal resource that supports psychological resilience and a sense of purpose during challenging life experiences; however, no validated assessment instrument currently exists to measure this construct within the Turkish cultural context. Method The scale was administered to 877 adults from various regions of Türkiye. The factor structure was examined using exploratory factor analysis (n = 405) and confirmatory factor analysis (n = 235). Results The final 7-item scale demonstrated acceptable psychometric properties (χ 2 /df = 1.35; RMSE = 0.03; CFI = 0.99; α = 0.88; λ = 0.88; ω = 0.88; CR = 0.90). Criterion validity was supported by moderate positive correlations with resilience ( r = .39), spiritual well-being ( r = .25), and grit ( r = .26). Discussion The findings indicate that the Turkish version of the Spiritual Fortitude Scale is a valid and reliable instrument for assessing spiritual fortitude. Future research is recommended to examine its applicability across diverse populations and applied settings.
