Abstract
BACKGROUND: Structural empowerment (SE) is an effective method of advancing work
environments and has previously been widely discussed in Western countries. Due to the lack of
culturally and academically accepted scales in Iran for measuring SE, localization of a foreign scale
in this field is necessary.
OBJECTIVES: This study aimed at investigating the validity and reliability of the Persian Version of
the 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 of
Medical 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 English
Version 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 using
test–retest and Cronbach’s alpha for internal consistency reliability.
RESULTS: The CWEQ‑II‑PV showed good content validity (the mean content validity scores for
relevancy, clarity, and simplicity were 94%, 96%, and 94%, respectively). In the CFA, the original
six‑factor version with 19 items was confirmed. The original model was presented and incorporated in
the 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’s
alpha 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 correlation
coefficients 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 scale
that measures the quality of the work environment for nurses from a SE perspective.
