MEDIATION EFFECTS OF OVERCOMMITMENT ON EFFORT, REWARD, INSOMNIA, AND WELL-BEING AS MODERATED BY GENDER, AGE, AND JOB...

Area of Science:

• Occupational Health Psychology
• Industrial-Organizational Psychology
• Health Sciences

Background:

• Occupational stress is a significant concern in the electronic manufacturing service industry.
• Understanding the interplay between occupational stress, insomnia, and well-being is crucial for employee health.
• The mediating role of over-commitment and moderating effects of demographic factors require investigation.

Purpose of the Study:

• To examine the mediating effect of over-commitment between occupational stress (effort and reward) and health outcomes (insomnia and well-being).
• To analyze the moderating roles of gender, age, and job position in these relationships.
• To validate the Effort-Reward-Insomnia-Well-being model using structural equation modeling.

Main Methods:

• A cross-sectional study involving 1,618 employees from the electronic manufacturing service industry in Hunan Province, China.
• Data collected via self-rated questionnaires after obtaining written informed consent.
• Structural equation modeling (SEM) was employed to fit and validate the proposed model.

Main Results:

• The final SEM model demonstrated satisfactory global goodness of fit.
• Effort was indirectly associated with insomnia and directly/indirectly with well-being.
• Reward showed direct associations with insomnia and well-being, and indirect associations via over-commitment.
• Over-commitment significantly mediated the relationships between effort, reward, and health outcomes.
• Gender, age, and job position moderated the associations between occupational stress and health outcomes.

Conclusions:

• Over-commitment plays a key mediating role in the relationship between occupational stress and health outcomes.
• The impact of occupational stress on employee well-being and insomnia is influenced by individual characteristics like gender, age, and job position.
• The findings support the Effort-Reward-Insomnia-Well-being model and highlight the importance of considering over-commitment and covariates in occupational health interventions.
