Are return to work beliefs, psychological well-being and perceived health related to return-to-work intentions among women on long-term sick leave for common mental disorders? A cross-sectional study based on the theory of planned behaviour

BACKGROUND: Long-term sick leave due to common mental disorders (CMDs) is a great burden in society today, especially among women. A strong intention to return to work (RTW) as well as symptom relief may facilitate RTW in this group. However, there is a lack of knowledge regarding what constitutes a strong intention. The Theory of Planned Behaviour is well-suited to identifying underlying beliefs about intentions to perform a behaviour. By including psychological well-being and perceived health, a more comprehensive picture of determinants of RTW intention might be achieved. Thus, the aim of the present study was to identify associations between RTW beliefs, psychological well-being, perceived health and RTW intentions among women on long-term sick leave due to CMDs, and to do so based on the Theory of Planned Behaviour. METHODS: The study was cross-sectional. Between October 2019 and January 2020, 282 women on long-term sick leave (> 2 months) due to CMDs were included in the study. The questionnaires for data collection were: “RTW Beliefs Questionnaire”, the “General Health Questionnaire -12” and the “EuroQol Visual Analogue Scale”. Standard multiple regression analysis was performed both with and without adjustment for potential confounders. RESULTS: The results showed that a more positive attitude towards RTW, stronger social pressure to RTW, higher perceived control over RTW and higher psychological well-being were associated with stronger RTW intention. The adjusted analysis eliminated the importance of psychological well-being for RTW intention, but showed that women who reported that their employer had taken actions to facilitate their RTW had stronger RTW intention. CONCLUSION: The RTW beliefs, derived from the Theory of Planned Behaviour, were all important for a strong RTW intention, while psychological well-being and perceived health showed weaker associations. Furthermore, having an employer that take actions for facilitating RTW was associated with stronger RTW intentions. Though some caution is warranted regarding the representativeness of the sample, the results do improve our understanding of some important determinants of RTW intention among women on long-term sick leave for CMDs.
