This scoping review aimed to synthesise the existing literature on self-undermining behaviours in the workplace, with a particular focus on their development as a concept and their application in occupational contexts. The method followed was the guidelines of the PRISMA extension for scoping reviews (PRISMA-ScR). A search was conducted using electronic databases (e.g., ScienceDirect, Scopus, EBSCOhost) and online platforms (e.g., ResearchGate). The list of references from the included studies was also assessed for any additional papers that could be relevant. The review's inclusion criteria were as follows: studies published in peer-reviewed journals only in English that explored self-undermining. Of the 60 papers identified, eight studies with 4,046 participants were included; the majority followed a quantitative method and a cross-sectional design. Self-undermining was positively associated with burnout and job demands. Self-undermining mediated the relationship between several work-related factors and outcomes. The studies in this review had limitations, e.g., self-reported data. Strategies to monitor and reduce self-undermining may be a crucial intervention to prevent burnout. Organisations shall develop and implement different programs to reduce these behaviours among employees.","PeriodicalId":13531,"journal":{"name":"Industrial Health","volume":" ","pages":"250-261"},"PeriodicalIF":1.6,"publicationDate":"2026-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13186620/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145206448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A qualitative analysis was conducted on the articles meeting the selection criteria, and the data were summarised based on the main risk factors identified. There is some evidence supporting work organisation as being at risk of alcohol consumption. This concerns mainly shift work and long-working hours, although the relation with drinking behaviours seems to be conflicting. Social relations and interactions within the workplace may induce (or be at risk of) alcohol consumption, particularly in the case of tolerant standards. The results regarding work stress are contradictory. Data regarding physical workload are scarce. Most studies addressed alcohol consumption as a public health issue, in the labour force, and not as an occupational health issue focused on work situations and conditions. Yet this knowledge may help the occupational physician to question the work environment, in order to prevent this risk on a collective technical level and on an individual case-by-case basis.","PeriodicalId":13531,"journal":{"name":"Industrial Health","volume":" ","pages":"233-241"},"PeriodicalIF":1.6,"publicationDate":"2026-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13186625/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145137346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates whether artistic leisure moderates the association between employment status and mental health, measured with the 12-item Chinese Health Questionnaire (CHQ-12), using nationally representative survey data from Taiwanese adults aged 18 and above. Participants were categorised into three groups. Descriptive statistics summarised mental health prevalence, and χ2 tests assessed associations across age groups. Hierarchical multivariable logistic regression, adjusted for sociodemographic factors, religious affiliation, financial sufficiency, and physical health, was employed to examine the relationship. The prevalence of good mental health was highest among older adults (84.83%), followed by young (79.25%) and middle-aged adults (78.76%). Artistic leisure significantly moderated the association between employment and mental health in young adults, with those in employment who engaged in artistic activities reporting better outcomes (AOR=4.22, 95% CI: 1.98-8.96). No significant moderating association was found in the older age groups. These findings suggest that employment plays a critical role in the mental well-being of young adults, highlighting the importance of understanding the contexts and motivations behind their engagement in artistic leisure.","PeriodicalId":13531,"journal":{"name":"Industrial Health","volume":" ","pages":"262-272"},"PeriodicalIF":1.6,"publicationDate":"2026-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13186622/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145137357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Support activities in the Health Emergency Operation Center (acute phase) and an unsafe work environment (subacute phase) were also significantly associated with presenteeism. The environmental determinants of presenteeism differed in the acute and subacute phases. However, potential confounding, including responder characteristics, could not be adjusted due to data limitations, so results should be interpreted cautiously.

UHNs were assessed based on self-reported experiences of forgoing necessary medical care. HRPL, work ability, and work engagement were measured using validated instruments. The generalized estimating equation models to repeated measurements applied to examine associations between UHNs and labor-related outcomes, adjusting for sociodemographic factors. Workers with UHNs had a 9.517 percentage point higher HRPL, 3.348-fold higher odds of poor work ability, and 1.506-fold higher odds of low work engagement compared with those without UHNs. Among causes of UHNs, financial constraints were associated with the largest increases in HRPL, poor work ability and low work engagement. These findings suggest that inadequate access to healthcare not only affects individual health but also has substantial implications for labor outcomes.

An Internet-based cross-sectional survey was conducted with 800 participants (four groups of 200 each): two groups engaged in professional and planning work under a discretionary labor system, and two comparable groups of non-discretionary workers. The discretionary labor system in Japan allows employees greater autonomy over working hours while evaluating performance based on deemed working time rather than actual hours worked. Among professional workers, burnout (emotional impairment), SEWB, workaholism, and work engagement were significantly higher in discretionary compared with non-discretionary workers. Multiple regression analyses showed burnout was positively associated with SEWB and workaholism in both professional groups. Among planning workers, SEWB and work engagement were higher in discretionary workers, whereas burnout did not differ significantly. Burnout was positively associated with workaholism in both groups and with SEWB only in non-discretionary workers.

Subjective sleep was assessed with the Insomnia Severity Index at baseline, last weeks of the intervention, and 8-month follow-up. Objective sleep outcomes (total sleep time, sleep efficiency, fragmentation index, and wake after sleep onset) were assessed through actigraphy at baseline, first and last weeks of the intervention. Mixed-effects models analyzed changes in subjective and objective sleep outcomes, adjusting for age, chronotype and household composition. The sleep intervention group had significantly higher insomnia scores at baseline, which improved to control levels post-intervention and remained so at follow-up. However, no significant changes in objective sleep were observed. The nutrition intervention group showed no significant effects on subjective or objective sleep outcomes.
