Workers' experiences of improvements in the work environment and mental health problems: a web-based 1-year prospective study of Japanese employees.
Article in Journal of occupational health, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesThis study aimed to prospectively investigate the association between work environment improvements and multiple mental health outcomes in a large sample of Japanese employees.
methodsA web-based longitudinal study surveyed 20 000 Japanese employees, 7970 of whom completed a follow-up after 1 year. Various types of work environment improvements experienced by workers were assessed using a 24-item checklist. Three mental health outcomes (poor mental health, presenteeism, and high psychosocial stress) were assessed and defined using standardized questionnaires.
resultsOverall, as the total number of work environment improvements increased, the odds ratio for mental health outcomes in the follow-up survey decreased by several percentage points, even after adjusting for demographic and occupational factors. Analysis of the types of work environment improvements showed that mutual support improvements were particularly effective in reducing mental health issues. The subgroup analyses also showed that the effectiveness of workplace environment improvements might vary between secondary and tertiary industry workers depending on the types of improvements and mental health outcomes.
conclusionsThe study suggests that workplace improvements can significantly affect mental health. The effectiveness of these improvements may vary according to the type of intervention, industry of the targeted workers, and mental health outcomes. This study provides basic data on the effectiveness of workplace environment improvements that can be used for future intervention trials.
