Purpose Workstyle can be defined as an individual pattern of cognitions, behaviours and physiological reactivity that can occur while performing job tasks. Workstyle has been associated with the development of musculoskeletal disorders (MSDs) amongst office workers in developed countries. However, little is known about the contribution of workstyle on MSDs in developing countries such as Malaysia. The objective of this cross-sectional study was to examine the relationship between workstyle and musculoskeletal discomfort in a sample of office workers in Malaysia. Methods Office workers (N = 417; response rate 65.5 %) from four organisations completed a survey measuring physical and psychosocial hazards, job satisfaction, work-life balance, workstyle, and MSD discomfort levels. Hierarchical regression analyses were undertaken to examine predictors associated with self-reported musculoskeletal discomfort, and more specifically the relationship between workstyle and MSD discomfort. Results Musculoskeletal discomfort was significantly associated with working through pain, mental health, physical demands, gender and work-life balance (R2 = 50.2, adjusted R2 = 0.48; F (13, 324) = 25.09, p = 0.001). Working through pain is the strongest risk factor associated with MSD discomfort (s = 0.49, p = 0.001) compared to other potential risk factors. Conclusions Working through pain is influenced by work, social culture and religious beliefs. Workplace MSDs interventions that focus on the impact of physical and psychosocial hazards with emphasis on addressing adverse workstyles should take into account aspects related to work and social culture of the target population. Changes are recommended at both employee and management levels such as better communications and understanding concerning workplace problems with regards to minimizing MSDs at work.

Purpose Work absence can result in substantial losses to the economy and workers. As a result, identifying modifiable factors associated with return-to-work (RTW) following an injury or illness is the focus of many empirical investigations. Self-efficacy, the belief about one's ability to undertake behaviours to achieve desired goals, has been identified as an important factor in RTW for injured workers. This paper systematically reviewed the literature on the association between self-efficacy and RTW outcomes for workers with an upper-body musculoskeletal injury or psychological injury. Methods A systematic search was conducted across five databases using two main search concepts- 'self-efficacy' and 'RTW'. After removing duplicates, our search strategy identified 836 studies, which were screened for relevance using titles and abstracts. Results A two stage screening process reduced the study pool to six studies using psychological injury cohorts and three using upper-body musculoskeletal (UB-MSK) cohorts. Eight cohorts from seven prospective cohort studies and one sample from a randomised control trial (RCT) were subjected to a risk of bias assessment. Higher levels of self-efficacy appeared to have a consistent and positive association with RTW across return-to-work status and work absence outcomes, injury type and follow-up periods. Effect ratios ranged from 1.00 to 5.26 indicating a potentially large impact of self-efficacy on RTW outcomes. The relationship between self-efficacy and RTW strengthened as the domain of self-efficacy became more specific to RTW and job behaviours. Studies assessing workers with psychological injuries were of a lower quality compared to those assessing workers with UB-MSK injuries. Conclusions Higher self-efficacy had consistent positive associations with RTW outcomes. Further empirical research should identify the determinants of self-efficacy, and explore the processes by which higher self-efficacy improves RTW outcomes.

Objective To examine if the factors associated with days of absence following a work-related injury are similar for mental health versus musculoskeletal (MSK) conditions. Methods A secondary analysis of wage replacement workers’ compensation claims in the state of Victoria, Australia. We examined the relationship between individual, injury, occupational and workplace variables with days of wage replacement over the 2-year period following first day of absence from work separately for mental health claims and MSK claims using negative binomial regression models. Results Mental health conditions were associated with a greater number of days of absence over the 2 years following first incapacity compared to MSK conditions. Differences were observed in employment, injury and industry variables on absence from work for mental claims compared to MSK claims. Working in the agriculture, forestry, fishing and mining industries and employment with a small organisation were more strongly associated with the number of days of wage-replacement among MSK compared to mental health claims, and working in the public administration and safety, or education and training industries or being employed in a position with high time pressure were associated with greater days of wage-replacement among mental health compared to MSK claims. Conclusions Predictors of days away from work in the 2 years following an injury differ for mental health versus MSK claims. Given the increasing number of mental health claims in Australia more research is required to understand differences in return-to-work for this group of claimants compared to those with physical injuries.
