Does disability status modify the association between psychosocial job quality and mental health? A longitudinal fixed-effects analysis

BACKGROUND: People with disabilities have difficulties in obtaining work. However, evidence suggests that those with disabilities derive substantial mental health benefits from employment. This paper assesses how the relationship between work and mental health is influenced by psychosocial job quality for people working with a disability. METHODS: The study design was a longitudinal cohort with 13 annual waves of data collection, yielding a sample of 122,883 observations from 21,848 people. Fixed-effects within-person regression was used to control for time invariant confounding. The Mental Component Summary (MCS) of the Short Form 36 (SF-36) measure was used as the primary outcome measure. The main exposure was a six-category measure of psychosocial job quality and employment status (including 'not in the labour force' [NILF] and unemployment). Disability status ('no waves of disability reported' and 'all contributed waves with reported disability') was assessed as an effect modifier. We also conducted a secondary analysis on respondents contributing both disability and non-disability waves. RESULTS: For those with no disability, the greatest difference in mental health (compared to optimal employment) occurs when people have the poorest quality jobs (-2.12, 95% CI -2.48, -1.75, p < 0.001). The relative difference in mental health was less in relation to NILF and unemployment (-0.39 and -0.66 respectively). For those with consistent disability, the difference in mental health when employed in an optimal job was similar between the poorest quality jobs (-2.25, 95% CI -3.84, -0.65, p = 0.006), NILF (-2.84, 95% CI -4.49, -1.20, p = 0.001) or unemployment (-2.56, 95% CI -4.32, -0.80, p = 0.004). These results were confirmed by the secondary analysis. CONCLUSIONS: Efforts to improve psychosocial job quality may have significant mental health benefits for people with disabilities. This will contribute to the economic viability of disability employment insurance schemes in Australia and other high-income countries.

On the potential for psychological researchers and psychologists to promote the social inclusion of people with disability: A review

© 2015 Australian Psychological Society. Objective: This paper outlines different approaches to understanding disability and describes ways in which psychological researchers and psychologists can promote the social inclusion of people with disability. Method: Narrative review drawing on writings and research from psychology and disability studies. Results: Five prominent models of disability appear in the literature (moral, medical, social, biopsychosocial, and post-modern), all of which have relevance to the lives of people with disability. Conceptualisations commonly used to understand the experience of disability from a psychological perspective include stigma and psycho-emotional disablism. There is evidence that people with disability wish to have greater involvement in research (e.g., as consultants and partners in research about them, and as participants in mainstream research) and to see research findings translated into practice. Evidence is emerging that can be used to underpin psychologists work with (a) communities (to foster social change and social justice, and to reduce stigma); (b) organisations, such as schools, workplaces, and disability service providers (to help develop inclusive and supportive environments); (c) families (to promote optimism, alternative understandings of disability, and a sense of control, as well as developing behaviour support plans and providing referrals to other sources of practical support); and (d) people with disability (to assist them with the issues they bring to therapy while being mindful of the potential for psycho-emotional disablism to colour the material presented). Conclusion: Psychological researchers and psychologists have significant potential to contribute to the social inclusion of people with disability.
