German Adaptation of the Subjective Vitality Scales (SVS-G)

Abstract Subjective vitality is a positive feeling of aliveness and energy, and it is a crucial aspect of well-being. The Subjective Vitality Scales (SVS) have been developed to measure subjective vitality both at the individual difference level and the state level in English-speaking samples. We translated the SVS into German (the SVS-G) and examined their psychometric properties. In Study 1 (N=260), we found that two correlated factors (Factor 1: individual difference level; Factor 2: state level) with five items each constituted a useful structure for the SVS-G. Moreover, the scores on the individual difference scale were more stable than the scores on the state scale. We also found partial evidence for the measurement invariance over a period of three weeks. Conforming to our expectations, Study 2 (N=296) revealed that the SVS-G scores were related to positive and negative affect but could still be distinguished from the affect variables. In line with previous findings, Study 3 (N=203) showed that SVS-G scores are related to well-being variables (happiness and joviality) and the perceived capacity to actively perform effortful tasks (attentiveness and capacity for self-control). Across all the studies, the SVS-G showed satisfying inner consistency, and the two consideration levels (individual differences vs. state) could be differentiated. The initial evidence suggests that overall, the SVS-G have good psychometric properties.
