Validity and Reliability Study of the Turkish Version of the Trauma-Informed Climate Scale-10 in Healthcare Settings

Abstract

Objective: This study aimed to adapt the Trauma-Informed Climate Scale–10 (TICS-10) into Turkish and evaluate its psychometric properties among healthcare professionals in Türkiye. Methods: This methodological, cross-sectional study included 410 healthcare professionals working in various healthcare institutions in Türkiye. The Turkish adaptation followed translation, back-translation, and expert review procedures. Structural validity was examined using principal component analysis (PCA) and confirmatory factor analysis (CFA). Internal consistency was assessed using Cronbach’s alpha, McDonald’s omega, and Guttman’s lambda. Test–retest reliability was evaluated in 49 participants using Pearson’s correlation and the intraclass correlation coefficient (ICC). Convergent validity was assessed through correlations with the Moral Injury Symptom Scale–Healthcare Professionals (MISS-HP). Results: PCA supported a unidimensional structure explaining 50.52% of the variance. CFA confirmed this structure with acceptable fit (χ²(32) = 203.36, CFI = .915, TLI = .89, SRMR = .056). Internal consistency was high (α = .89, ω = .89, λ = .89), with CR = .91 and AVE = .51. Corrected item–total correlations ranged from .50 to .72. Test–retest reliability was good (ICC = .72, 95% CI [.20, .89]; r = .83, p < .001). Convergent validity was supported by a moderate negative correlation with MISS-HP scores. Conclusion: The Turkish TICS-10 demonstrated acceptable reliability and validity and may be useful for assessing trauma-informed organizational climate in Turkish healthcare settings.
