Evaluating the effectiveness and cost-benefit of a worksite mental health program among manufacturing workers: A study protocol for a quasi-experimental study.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMental health problems lead to the loss of about 12 billion workdays worldwide each year. This creates a major economic burden. In food manufacturing, workers often face various psychosocial stressors. These include high workload, time constraint, repetitive tasks, and low autonomy. These conditions can affect both mental health and work performance. Workplace mental health interventions have shown promising results in mental health improvement. However, most studies come from high-income countries and service sectors. There is still limited evidence from industrial settings in middle-income countries. To address this gap, a structured Worksite Mental Health Program (WMHP) was developed.
methodThis study will employ a quasi-experimental two arm repeated measures design among workers from food manufacturing factories in Malaysia. The intervention group will receive an eight week WMHP including psychoeducation, mindfulness practices, progressive muscle relaxation, and breathing exercises. The comparison group will continue with routine workplace practices and receive a general mental health information pamphlet. Assessments will be carried out at baseline, one month post intervention, and at three months follow up. Primary outcomes include depression, anxiety, stress, and burnout. Secondary outcomes include job satisfaction, absenteeism, presenteeism, and economic outcomes. Changes over time will be analysed using Generalised Estimating Equations (GEE). A cost-benefit analysis (CBA) will also be conducted to assess economic impact. ANTICIPATED
resultsThe program is expected to improve mental health and work performance, while simultaneously reducing absenteeism and presenteeism. The economic evaluation is expected to demonstrate positive productivity gains associated with the program.
conclusionThis study will provide evidence on the effectiveness and economic value of a workplace mental health intervention in an industrial setting, informing workplace health strategies in Malaysia and similar contexts.
