    Social support and supervisory quality interventions in the workplace: a stakeholder-centered best-evidence synthesis of systematic reviews on work outcomes
    (National Iranian Oil Company (N I O C) Polyclinics, 2015) Wagner, S. L.; White, M. I.; Schultz, I. Z.; Williams-Whitt, Kelly; Koehn, C.; Dionne, C. E.; Koehoorn, M.; Harder, H. G.; Pasca, R.; Wärje, O.; Hsu, V.; McGuire, L.; Lama, I.; Schulz, W.; Kube, D.; Wright, M. D.
    Background: There is controversy surrounding the impact of workplace interventions aimed at improving social support and supervisory quality on absenteeism, productivity and financial outcomes. Objective: To determine the value of social support interventions for work outcomes. Methods: Databases were searched for systematic reviews between 2000 and 2012 to complete a synthesis of systematic reviews guided by the PRISMA statement and the IOM guidelines for systematic reviews. Assessment of articles for inclusion and methodological quality was conducted independently by at least two researchers, with differences resolved by consensus. Results: The search resulted in 3363 titles of which 3248 were excluded following title/ abstract review, leaving 115 articles that were retrieved and underwent full article review. 10 articles met the set inclusion criteria, with 7 focusing on social support, 2 on supervisory quality and 1 on both. We found moderate and limited evidence, respectively, that social support and supervisory quality interventions positively impact workplace outcomes. Conclusion: There is moderate evidence that social support and limited evidence that supervisory quality interventions have a positive effect on work outcomes.

    Physical activity and exercise interventions in the workplace impacting work outcomes: a stakeholder-centered best evidence synthesis of systematic reviews
    (National Iranian Oil Company (N I O C) Polyclinics, 2016) White, M. I.; Dionne, C. E.; Wärje, O.; Koehoorn, M.; Wagner, S. L.; Schultz, I. Z.; Koehn, C.; Williams-Whitt, Kelly; Harder, H. G.; Pasca, R.; Hsu, V.; McGuire, L.; Schulz, W.; Kube, D.; Wright, M. D.
    Background: The prevention of work disability is beneficial to employees and employers,, and mitigates unnecessary societal costs associated with social welfare. Many service providers and employers have initiated workplace interventions designed to reduce unnecessary work disability. Objective: To conduct a best-evidence synthesis of systematic reviews on workplace interventions that address physical activities or exercise and their impact on workplace absence, work productivity or financial outcomes. Methods: Using a participatory research approach, academics and stakeholders identified inclusion and exclusion criteria, built an abstraction table, evaluated systematic review quality and relevance, and interpreted the combined findings. A minimum of two scientists participated in a methodological review of the literature followed by a consensus process. Results: Stakeholders and researchers participated as a collaborative team. 3363 unique records were identified, 115 full text articles and 46 systematic reviews were included, 18 assessed the impact of physical fitness or exercise interventions. 11 focused on general workers rather than workers who were absent from work at baseline; 16 of the reviews assessed work absence, 4 assessed productivity and 6 assessed financial impacts. Conclusion: The strongest evidence supports the use of short, simple exercise or fitness programs for both workers at work and those absent from work at baseline. For workers at work, simple exercise programs (1–2 modal components) appear to provide similar benefits to those using more complex multimodal interventions. For workers off-work with subacute low back pain, there is evidence that some complex exercise programs may be more effective than simple exercise interventions, especially if they involve workplace stakeholder engagement, communication and coordination with employers and other stakeholders. The development and utilization of standardized definitions, methods and measures and blinded evaluation would improve research quality and strengthen stakeholder-centered guidance.

    Mental health interventions in the workplace and work outcomes: a best-evidence synthesis of systematic reviews
    (National Iranian Oil Company (N I O C) Polyclinics, 2016) Wagner, S. L.; Koehn, C.; White, M. I.; Harder, H. G.; Schultz, I. Z.; Williams-Whitt, Kelly; Wärje, O.; Dionne, C. E.; Koehoorn, M.; Pasca, R.; Hsu, V.; McGuire, L.; Schulz, W.; Kube, D.; Wright, M. D.
    Background: Mental health issues in the workplace are a growing concern among organizations and policymakers, but it remains unclear what interventions are effective in preventing mental health problems and their associated organizational consequences. This synthesis reports on workplace mental health interventions that impact absenteeism, productivity and financial outcomes. Objective: To determine the level of evidence supporting mental health interventions as valuable to work outcomes. Methods: Databases were searched for systematic reviews between 2000 and 2012: Medline, EMBASE, the Cochrane Database of Systematic Reviews, DARE, CINAHL, PsycINFO and TRIP. Grey literature searches included health-evidence.ca, Rehab+, National Rehabilitation Information Center (NARIC), and Institute for Work and Health. The assessment of articles for inclusion criteria and methodological quality was conducted independently by two or more researchers, with differences resolved through consensus. Results: The search resulted in 3363 titles, of which 3248 were excluded following title/abstract review, with 115 articles retrieved for full-text review. 14 articles finally met the inclusion criteria and are summarized in this synthesis. Conclusion: There is moderate evidence for the effectiveness of workplace mental health interventions on improved workplace outcomes. Certain types of programs, such as those incorporating both mental and physical health interventions, multicomponent mental health and/or psychosocial interventions, and exposure in vivo containing interventions for particular anxiety disorders had a greater level of research evidence to support their effectiveness.

    Job demand and control interventions: a stakeholder-centered best-evidence synthesis of systematic reviews on workplace disability
    (National Iranian Oil Company (N I O C) Polyclinics, 2015) Williams-Whitt, Kelly; White, M. I.; Wagner, S. L.; Schultz, I. Z.; Koehn, C.; Dionne, C. E.; Koehoorn, M.; Harder, H.; Pasca, R.; Wärje, O.; Hsu, V.; McGuire, L.; Schulz, W.; Kube, D.; Hook, A.; Wright, M. D.
    Background: Physical and psychological job demands in combination with the degree of control a worker has over task completion, play an important role in reducing stress. Occupational stress is an important, modifiable factor affecting work disability. However, the effectiveness of reducing job demands or increasing job control remains unclear, particularly for outcomes of interest to employers, such as absenteeism or productivity. Objective: This systematic review reports on job demand and control interventions that impact absenteeism, productivity and financial outcomes. Methods: A stakeholder-centered best-evidence synthesis was conducted with researcher and stakeholder collaboration throughout. Databases and grey literature were searched for systematic reviews between 2000 and 2012: Medline, EMBASE, the Cochrane Database of Systematic Reviews, DARE, CINAHL, PsycINFO, TRIP, health-evidence.ca, Rehab+, National Rehabilitation Information Center (NARIC), and Institute for Work and Health. Articles were assessed independently by two researchers for inclusion criteria and methodological quality. Differences were resolved through consensus. Results: The search resulted in 3363 unique titles. After review of abstracts, 115 articles were retained for full-text review. 11 articles finally met the inclusion criteria and are summarized in this synthesis. The best level of evidence we found indicates that multimodal job demand reductions for either at-work or off-work workers will reduce disability-related absenteeism. Conclusion: In general, the impacts of interventions that aim to reduce job demands or increase job control can be positive for the organization in terms of reducing absenteeism, increasing productivity and cost-effectiveness. However, more high quality research is needed to further assess the relationships and quantify effect sizes for the interventions and outcomes reviewed in this study.
