Developing a job motivation scale: A focus on cross-cultural adaptation and validation among hospital staff

Abstract

ABSTRACT Objectives: This paper is to culturally adapt and confirm the validity and reliability of a job motivation scale among health workers in hospitals in Vietnam. Methods: We used data from two studies of health workers’ job motivation which were conducted at two public hospitals in Vietnam. These studies were conducted in 2016 in 2018. Exploratory factor analysis (EFA) was used to identify the motivation factors and confirmatory factor analysis (CFA) was then used to certify the elementary factors produced by EFA using Comparative Fit Index (CFI), Tucker Lewis Index (TLI), Root Mean Square Error of Approximation (RMSEA) and the Standardized Root Mean Square Residual (SRMR). Results: The results demonstrate that two factors of job motivation, namely ‘Satisfaction and Commitment’ and ‘Conscientiousness’ were identified by EFA with Cronbach’'s Alpha of 0.88 and 0.89 respectively. The whole scale of job motivation was reliable, with Cronbach’'s Alpha of 0.87. The result was confirmed by CFA where the motivation item corresponds as CFI (0.91), TLI (0.88) and RMSEA (0.087), SRMR (0.06) are good fit indices. Conclusions: Job motivation scale should be widely applied for measuring the health workers’ motivation in other hospitals in Vietnam. The necessary solutions should be implemented to improve health workers’ job motivation.
