Development and Validation of the Organisational Health Improvement Questionnaire-Core (OHIQ-Core): A Brief Assessment of Workplace Psychological Health

The present study reports the development and validation of the Organisational Health Improvement Questionnaire (OHIQ-Core), a brief measure of organisational psychological health. Established theories and frameworks were used to identify an initial four-dimensional conceptual model to guide the generation of candidate items and selection of the final 14-item questionnaire. Data were collected from 1,026 employees across multiple organisations in different industries. An exploratory factor analysis (EFA) yielded a two-factor structure reflecting ‘Organisational Support’ and ‘Work Design’. Confirmatory Factor Analysis (CFA) in an independent sample (n = 513) confirmed this structure and supported a higher-order organisational health factor. Model fit indices suggested good fit (CFI = .96, TLI = .95, RMSEA = .06, SRMR = .05). Internal consistency was good (ω = .86–.94), with satisfactory composite reliability and convergent validity. The OHIQ-Core total score correlated with wellbeing (WHO-5; r = .62), supporting convergent validity. Results suggested that organisational psychological health can be viewed as a unified construct encompassing structural and relational domains. The OHIQ-Core provides a psychometrically sound and practical tool for assessing, monitoring, and improving organisational psychological health.
