Abstract
Supporting the application of positive psychology in the workplace, the Shirom Melamed Vigor Scale (SMVS), which assesses vigorous feelings at work, was adapted to the Thai context. The Thai SMVS contains 14 items as in the original scale and was validated using a sample of 585 employed participants in Thailand. Results of a confirmatory factor analysis are consistent with the conceptual model of vigour as consisting of physical strength, cognitive liveliness, and emotional energy, with a suggestion that a 13-item scale can also be used. As expected, vigour has been found to be conceptually distinct from some similar constructs, and independent from job burnout. Vigour also showed unique predictive effects on employees’ health. These results support the previously-proposed conceptual framework of vigour and indicate crucial roles of positive emotion in the work setting. In concordance with a positive organisational psychology approach, applications of the Thai vigor scale are discussed with respect to its potential for enhancing employees’ wellbeing and productivity.
Highlights
S upporting the application of positive psychology in the workplace, the Shirom Melamed Vigor Scale (SMVS), which assesses vigorous feelings at work, was adapted to the Thai context
Results show that the T-SMVS total score had moderate correlations with the negative constructs of emotional exhaustion (r = −.43, p < .001, n = 140) and negative affect at work (r = −.33, p < .001, n = 140), as well as self-esteem (r = .49, p < .001, n = 140)
Findings support all of the hypotheses, indicating that the developed T-SMVS was a reliable tool and that vigour is a robust affective construct in workplace setting
Summary
S upporting the application of positive psychology in the workplace, the Shirom Melamed Vigor Scale (SMVS), which assesses vigorous feelings at work, was adapted to the Thai context. For work-related outcomes, vigour was the strongest predictor of job performance above job involvement, perceived organisational support, and work engagement (Steele et al, 2012; see Carmeli, Ben-Hador, Waldman, & Rupp, 2009) After reviewing these researches, it seems logical that exploring the role of this positive affective state in Thai employees is important. The 14-item SMVS developed by Shirom (2004) consists of three subscales reflecting three theoretical dimensions of vigour, namely: physical strength (PS; five items); cognitive liveliness (CL; five items); and emotional energy (EE, four items) Respondents rate how they feel each kind of strength within the past 30 working days on a 7point Likert scale ranging from 1 (never or almost never) to 7 (always or almost always).
