Psychometric properties of the Turkish version of the Nordic Occupational Safety Climate Questionnaire (NOSACQ-50).

Abstract

BackgroundOccupational safety climate, a key predictor of workplace safety performance and employee well-being, requires culturally adapted and psychometrically robust measurement tools such as the NOSACQ-50 to effectively assess safety perceptions across different industries and populations.ObjectiveThis study aimed to conduct the cross-cultural adaptation of the interview-administered Turkish version of the Nordic Occupational Safety Climate Questionnaire (NOSACQ-50) and to assess its psychometric properties in the metal industry.MethodsA methodological study was conducted among 387 employees working in a metal industry enterprise in Balikesir BEST Transformer. Internal consistency was assessed using Cronbach's α, construct validity was examined through confirmatory factor analysis (CFA) and known-groups comparisons, and discriminant validity was evaluated via correlation analyses with related scales. Statistical analyses were performed using SPSS 27.0 and Jamovi 2.3.28.ResultsThe Turkish version of NOSACQ-50 comprises seven subscales, with Cronbach's α coefficients ranging from 0.85 to 0.92. Person reliability values from Rasch analysis ranged between 0.81 and 0.87. CFA demonstrated acceptable model fit indices for all subscales. Significant correlations were observed between NOSACQ-50 subscales and the peer support, supervisor support, sense of community, trust, job satisfaction, and burnout subscales of the KOPSOR-TR. Furthermore, NOSACQ-50 subscales showed significant associations with the subscales of the Safety Climate Scale, supporting convergent validity.ConclusionsThe Turkish version of NOSACQ-50 demonstrates satisfactory reliability and validity, and it can be used as a standardized tool for assessing occupational safety climate among employees in Turkey.
