Work Needs Satisfaction Scale- Spanish Version: Psychometric Properties and Validity Evidence

With a growing Latinx workforce in the U.S., many of whom are Spanish-speaking, there is a pressing need to examine key constructs related to vocational well-being in this population. The aim of the current study was to validate a Spanish language version of the Work Needs Satisfaction Scales (WNSS; Autin et al., 2019). The WNSS comprises a set of scales developed to measure satisfaction of survival, social contribution, autonomy, competence, and relatedness needs, all of which are theorized to be key mediators in the link from decent work to well-being and work fulfillment. Using cross-sectional data across two samples of Latinx workers, we tested the reliability and validity of a Spanish language version of the WNSS (WNSS-SV). In Study 1 we conducted an exploratory factor analysis (EFA) with a sample of 195 participants. This resulted in a 19-item scale with five factors mirroring those of the English language scale. In Study 2 (N = 377), we examined factor structure and model fit using confirmatory factor analysis (CFA); measurement invariance across gender, language, and social class group; and concurrent validity. Results from Study 2 demonstrated the model was a good fit to the data; showed concurrent validity; and provided support for measurement invariance. Thus, overall results indicated that the WNSS-SV may serve as a useful tool for future research on work-related need satisfaction among Latinx workers. A discussion regarding the importance of these findings and implications for practice and research are provided.
