چکیده
BACKGROUND: Structural empowerment (SE) is an effective method of advancing workenvironments and has previously been widely discussed in Western countries. Due to the lack ofculturally and academically accepted scales in Iran for measuring SE, localization of a foreign scalein this field is necessary.OBJECTIVES: This study aimed at investigating the validity and reliability of the Persian Version ofthe Conditions of Work Effectiveness Questionnaire‑II (CWEQ‑II‑PV) among Iranian nurses.METHODS: The present cross‑sectional methodological research was conducted during 2017–2018.Participants were 230 nurses working in four teaching hospitals affiliated to Kashan University ofMedical Sciences in Kashan, Iran, who were selected using quota sampling. A standard forward–backward translation procedure according to Wild et al. (2005) was used to translate the EnglishVersion of the CWEQ‑II to Persian. The psychometric evaluation processes were achieved by face,content, and construct validity (confirmatory factor analysis [CFA]). Reliability was examined usingtest–retest and Cronbach’s alpha for internal consistency reliability.RESULTS: The CWEQ‑II‑PV showed good content validity (the mean content validity scores forrelevancy, clarity, and simplicity were 94%, 96%, and 94%, respectively). In the CFA, the originalsix‑factor version with 19 items was confirmed. The original model was presented and incorporated inthe CFA, indicating an acceptable fit for the model (root mean square error of approximation = 0.06,comparative fit index = 0.92, goodness of fit index (GFI) = 0.94, and adjusted GFI = 0.91). Cronbach’salpha coefficient for the total scale was 0.84 and for each component ranged from 0.71 to 0.87,indicating good internal consistency, and the test–retest Spearman and intraclass correlationcoefficients were 0.93 and 0.87, respectively, showing good test–retest reliability.CONCLUSIONS: Evidence was found to support the reliability and validity of the CWEQ‑II‑PV scalethat measures the quality of the work environment for nurses from a SE perspective.
