Occupational Health and Well-being Questionnaire (OHWQ): an instrument to assess psychosocial risk and protective factors in the workplace.

OBJECTIVES: Psychosocial stressors at work have been identified as significant risk factors for several mental and physical health problems. These stressors must be compensated by psychosocial resources to prevent or reduce adverse effects on health. Questionnaires measuring these stressors and resources already exist, but none integrate digital stress, ethical culture, and psychosocial safety climate; factors that are increasingly linked to workers' health. This study aims to develop and establish the psychometric properties of one of the most comprehensive instruments measuring the psychosocial work environment to date: the Occupational Health and Well-being Questionnaire (OHWQ). STUDY DESIGN: A cross-sectional validation study is proposed to develop the OHWQ and document its psychometric properties. METHODS: The OHWQ was developed from validated instruments to which new items were added. The questionnaire includes psychosocial dimensions, along with indicators of psychological distress, musculoskeletal disorders, and well-being. It was administered to a sample of 2770 participants from a population working in the academic field. Exploratory and confirmatory factor analyses and the calculation of Cronbach's α coefficient were used to identify the variables, items, and, dimensions of the OHWQ and to document its main psychometric properties. RESULTS: The acceptability of the measurement model was evaluated by the reliability of the items, internal consistency between the items, and the convergent and discriminant validity. Construct validity was assessed using exploratory and confirmatory factor analyses. Using factor analyses and cut-off rules, the new instrument has 124 items grouped into 22 dimensions. The OHWQ demonstrated satisfactory reliability and validity, as well as reasonable fit indices. The internal consistency of the scales was also good (Cronbach's α = 0.68-0.96, median = 0.85). CONCLUSION: The OHWQ demonstrated good psychometric properties. It could be useful for both research purposes and for workplaces interested in developing concrete action plans aimed at improving the balance between psychosocial work stressors and resources.

Masked hypertension and effort-reward imbalance at work among 2369 white-collar workers.

Hypertension is an important risk factor of cardiovascular diseases, the leading cause of death worldwide. Adverse effects of psychosocial factors at work might increase the risk of masked hypertension, but evidences are still scarce. The objective of this study is then to determine whether adverse psychosocial work factors from the effort-reward imbalance (ERI) model are associated with the prevalence of masked hypertension in a population of white-collar workers. White-collar workers were recruited from three public organizations. Blood pressure was measured at the workplace for manually operated measurements (mean of the first three readings taken by a trained assistant) followed by ambulatory measurements (mean of all subsequent readings taken during the working day). Masked hypertension was defined as manually operated BP<140/90 mm Hg and ambulatory BP ⩾135/85 mm Hg. ERI exposure at work was measured using Siegrist's validated questionnaire. Blood pressure readings were obtained from 2369 workers (participation proportion: 85%). ERI exposure (OR: 1.53 (95% CI: 1.16-2.02) and high efforts at work (OR: 1.61 (95% CI: 1.13-1.29) were associated with masked hypertension, after adjusting for sociodemographic and cardiovascular risk factors. Workers exposed to an imbalance between efforts spent at work and reward had a higher prevalence of masked hypertension. High efforts at work might be of particular importance in explaining this association. Future studies should be designed to investigate how clinicians can include questions on psychosocial work factors to screen for masked hypertension and how workplace interventions can decrease adverse psychosocial exposures to lower BP.

Repeated exposure to effort-reward imbalance, increased blood pressure, and hypertension incidence among white-collar workers: effort-reward imbalance and blood pressure.

OBJECTIVES: To determine whether men and women with repeated ERI exposure have increased BP means or higher hypertension incidence over a 3-year follow-up. To examine the potential modifying effect of age and overcommitment. METHODS: The study cohort was composed of 1,595 white-collar workers (629 men and 966 women) assessed at baseline and 3-year follow-up. Ambulatory BP measures were taken every 15 min during a working day. ERI at work was self-reported using validated scales. BP means at follow-up and cumulative incidence of hypertension were respectively modeled with analyses of covariance (ANCOVA) and log-binomial regression. RESULTS: Among men, no association was observed between repeated ERI exposure and BP. Among women, age had a modifying effect. Women <45 years old exposed to ERI at both times had significantly higher BP means at follow-up (122.2/78.9 mmHg) than those unexposed (120.4/77.4 mmHg). In women ≥45 years old, the cumulative incidence of hypertension was 2.78 (95% CI: 1.26-6.10) times higher among those exposed to ERI at both times. Men and women in the higher tertile of overcommitment had higher BP means (men: 128.9/82.2 mmHg, women: 121.9/78.0 mmHg) than those in the lower tertile (men: 127.2/81.3 mmHg, women: 120.6/77.0 mmHg). CONCLUSION: This prospective study showed that, among women, repeated ERI exposure led to a significant age-specific increase in BP means and a major age-specific increase in hypertension incidence. These results suggest that primary intervention aimed at reducing ERI may contribute to lower BP and prevent hypertension in women.
