Development and Initial Validation of a Questionnaire Measuring Self-management Strategies that Promote Psychological Health at Work.

Background: Self-management strategies have been identified as a promising avenue to promote mental health and functioning at work. However, the absence of a validated questionnaire to assess the use of strategies that can be adopted in the workplace has limited empirical research on this topic. This study seeks to develop and validate a questionnaire measuring mental health self-management strategies used by workers to promote their mental health and functioning at work: the Workplace Mental Health Self-Management Questionnaire (WMHSQ).

Methods: An initial list of 72 self-management strategies was generated from the content of 25 interviews conducted with workers experiencing depressive or anxiety symptoms. Content experts on mental health at work identified the 47 most relevant items. To validate the WMHSQ, 365 workers completed the WMHSQ and criterion-related measures (depressive and anxiety symptoms, work functioning, self-management and coping). Two weeks later, 235 participants completed the WMHSQ once again.

Results: Principal component analysis revealed a four-factor solution composed of 21 self-management strategies: Managing Thoughts and Emotions, Managing Recovery, Managing Relationships and Managing Tasks. The WMHSQ shows adequate internal consistency and test-retest reliability. Correlational analyses support convergent and concurrent validity.

Limitations: Since this is an initial psychometric validation of the WMHSQ, only an exploratory factor analysis was performed. It will therefore be important to validate the structure of this new psychometric tool through confirmatory factor analysis in a subsequent study.

Conclusions: The strategies identified in the WMHSQ can form the basis for developing practical tools and interventions to promote mental health self-management at work.
