Scales are often adapted for the context in which they are used, which may involve simply adjusting items to orient the respondent to the study’s focal context. However, if a scale’s items are adapted to be context-specific (e.g., moving from general to workplace), will its psychometric properties change? This study aimed to investigate this question by evaluating measurement and structural equivalence of the PERMA-Profiler (PP) and its workplace adaptation, the Workplace Wellbeing Survey (WWS).
