Do multicomponent workplace health and wellbeing programs predict changes in health and wellbeing?

Organizations typically deploy multiple health and wellbeing practices in an overall program. We explore whether practices in workplace health and wellbeing programs cohere around a small number of archetypal categories or whether differences between organizations are better ex-plained by a continuum. We also examine whether adopting multiple practices predicts subse-quent changes in health and wellbeing. Using survey data from 146 organizations, we found differences between organizations were best characterized by a continuum ranging from less to more extensive adoption of practices. Using two-wave multilevel survey data at both individual and organizational level (N = 6,968 individuals, N = 58 organizations), we found that in organi-zations that adopt a wider range of health and wellbeing practices, workers with poor baseline psychological wellbeing were more likely to report subsequent improvements in wellbeing and workers that reported good physical health at baseline were less likely to report experiencing poor health at follow-up. We found no evidence that adopting multiple health and wellbeing practices buffered the impact of individuals’ workplace psychosocial hazards on physical health or psy-chological wellbeing
