Job resources do not mitigate the impact of job demands for workers with depression

Abstract Introduction Jobs characterized by low to moderate job demands and high job resources are associated with better work outcomes among healthy workers, yet it remains unclear whether this is the case for workers with depression. This study examined whether depression moderates the relationship between job demands, job resources, and maintaining employment. Methods Data from the longitudinal population-based Lifelines cohort study were matched with register data on employment status from Statistics Netherlands (n = 55,950). The two-way interaction between job demands and depression and the three-way interaction between job demands, job resources and depression were examined in a zero-inflated Poisson regression model with path 1 including a binary employment outcome and path 2 a count variable including months out of employment. Results The interaction effect of job demands and depression on being employed was significant (b=-0.22, 95% CI: -0.44; 0.01), showing that workers without depression were more likely to be employed whereas workers with depression were less likely to be employed if they had high job demands. The three-way interaction between job demands, job resources, and depression was significant for months out of employment (b = 0.15, 95% CI: 0.01; 0.29), indicating that workers with depression had more months out of employment when reporting high job demands and high job resources compared to workers without depression. Discussion Although increasing resources to prevent negative work outcomes may be beneficial for workers without depression, this approach might be limited for the vulnerable subgroup of workers with depression. Key messages While job demands are associated with a higher likelihood of employment during follow-up for workers without depression, this is not the case for workers with depression. Job resources do not help workers with depression who face high job demands.


Introduction:
Jobs characterized by low to moderate job demands and high job resources are associated with better work outcomes among healthy workers, yet it remains unclear whether this is the case for workers with depression. This study examined whether depression moderates the relationship between job demands, job resources, and maintaining employment. Methods: Data from the longitudinal population-based Lifelines cohort study were matched with register data on employment status from Statistics Netherlands (n = 55,950). The two-way interaction between job demands and depression and the three-way interaction between job demands, job resources and depression were examined in a zero-inflated Poisson regression model with path 1 including a binary employment outcome and path 2 a count variable including months out of employment.

Results:
The interaction effect of job demands and depression on being employed was significant (b = -0.22, 95% CI: -0.44; 0.01), showing that workers without depression were more likely to be employed whereas workers with depression were less likely to be employed if they had high job demands. The three-way interaction between job demands, job resources, and depression was significant for months out of employment (b = 0.15, 95% CI: 0.01; 0.29), indicating that workers with depression had more months out of employment when reporting high job demands and high job resources compared to workers without depression.

Discussion:
Although increasing resources to prevent negative work outcomes may be beneficial for workers without depression,

Background:
Public mental health (PMH) services address social determinants of mental health, such as poverty, poor housing, and job insecurity. Austerity and welfare reform in the UK has led to cuts to social and welfare support, increasing poor mental health and widening inequalities, exacerbated by COVID-19. State health services lack capacity to tackle social issues that contribute to a large proportion of expressed mental health need. Co-locating PMH services within community spaces is a potential solution to increase early access and improve quality of services. Using a realist evaluation, we sought to develop the theory on how community co-location affects PMH outcomes, who this works best for, and how this is impacted by the context of delivery.

Methods:
We collected data from service-users and service-providers at six case study sites across England, UK, using interviews (n = 62), four focus groups (n = 40) and two stakeholder workshops (n = 19).

Results:
We identified four overarching theories. First, community providers do not operate under the same limits as state services allowing them the flexibility and time to build trust and ongoing relationships with service users. Second, the ethos and culture of services is to empower users to access help and be independent. Third, accessing support from a shared local space allows a coordinated and holistic response reducing barriers such as distance, cost, and anxiety. Four, as they are recreational services and spaces for access by all with no predefined/required level of need they are better at promoting wellbeing and primary prevention.

Conclusions:
Community co-location of PMH services can strengthen the overall mental health system by widening reach to people vulnerable to poor mental health and enabling earlier intervention on associated social determinants. This has potential to reduce mental health inequalities and demand on the state health system. Key messages: Community co-location of PMH services can provide early and holistic support for complex social issues. There is potential to support the state health system by alleviating demand for help with 'non-health' issues.
