The development and validation of a Total Worker Health Climate Scale.

The purpose of this study is to develop a Total Worker Health Climate (TWH-c) Scale, addressing workers' perceptions of the relative priority of safety, physical health, and mental well-being in their organizations. It aims to fill a notable gap in Total Worker Health (TWH) literature: the absence of a validated scale assessing TWH perceptions in the workplace. Building upon the theory of organizational climate (Beus et al., 2023), two novel physical health and mental well-being subclimate scales were developed and joined with a validated safety climate scale to create an overall TWH-c Scale. This method includes four phases. First, items were generated based on literature review, cognitive interviews with job incumbents, and evaluations of subject matter experts. Second, factor analyses were conducted on three separate samples. Third, shared perceptions across units were tested to examine physical health climate and mental well-being climate as shared subclimates. Last, criterion-related validity was assessed through regression analyses. The resulting scale includes 40 items (16 safety climate items, 14 physical health climate items, and 10 mental well-being climate items) and provides scores for each subclimate and an overall TWH-c. Each subclimate was significantly related to important outcomes within its domain at the individual, unit, and organization levels. The overall TWH-c score was also linked to these outcomes in addition to unique job-related outcomes at all levels. This study provides the first psychometrically validated tool for measuring organizational TWH-c, an efficient method to assess TWH as a holistic climate. Further implications are discussed regarding its use and expansion. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
