[[alternative]]The relationship between sleep duration and burnout among cleaners in Taiwan：Mental health as the mediator variable.

[[abstract]]背景與目的：我國產業逐漸轉型為以服務業為主，如何在確保藍領工作者於職場中免於遭受安全健康風險危害，營造更佳的工作者職場環境，避免國家遭受更大的健保財政壓力及提高勞動參與率，都是大環境下即將面臨的課題，但藍領階層的清潔服務業往往是社會最忽視的一群，本研究主要目的（一）探討藍領清潔服務員睡眠時數與倦怠之關係。（二）探討以心理健康對藍領清潔服務員睡眠時數與倦怠的中介效果。研究方法：本研究採問卷調查研究法。研究對象為全國承攬軌道運輸業清潔之指標性公司之第一線清潔勞工共479人，使用勞動部異常工作負荷促發疾病預防指引之哥本哈根倦怠量表量測依變項個人倦怠與工作倦怠以及自變項睡眠時數，中介變項則使用台灣人憂鬱症量表量測心理健康程度；並經文獻探討後對性別、年齡、BMI(Body Mass Index)與工作場域進行控制。使用SPSS 21 for Windows中文統計套裝軟體，並嵌入安裝process擴充程式，進行Sobel test中介效果之驗證。本研究為一次性調查，故研究設計依資料蒐集時間屬橫斷性研究及初級資料。研究結果：本研究結果顯示，睡眠時數對工作倦怠與個人倦怠的影響，包含直接影響與間接影響，即心理健康在睡眠時數與個人/工作倦怠之間，具有中介效果。表示員工心理健康可視為個人資源，為影響倦怠不容忽視的重要因素。討論與建議：可驗證此中介效果及影響模式在藍領清潔工作者是確立的，未來在職場安全領域之學者，應可利用此架構驗證不同產業或白領工作者（較為專業，勞心非勞力的一群）於不同工作場域之情形，進而瞭解此模式在不同產業別及工作場域之差異，期盼能夠提供作為改善職場健康促進與改善勞動條件依據。[[abstract]]Background/Purpose:The industry in Taiwan has gradually transformed into a service industry. Therefore, it is imperative to prevent blue-collar workers exposed to safety and health risks in the workplace, create a better workplace environment for workers, avoid placing a more severe financial burden of the National Health Insurance, and increase labor force participation rate. The cleaning service industry of the blue-collar is the most neglected group in society. The purposes of this study are (1) to explore the relationship between sleep duration and burnout among blue-collar cleaners and (2) to explore the mediating effect of mental health on sleep hours and burnout among blue-collar cleaners.Method:This study adopts the questionnaire survey method. There were 479 train cleaners, using the Copenhagen Burnout Inventory from ‘Guideline for Preventing Diseases Caused by Exceptional Workload’ released by the Occupational Safety and Health Administration of the Ministry of Labor, to measure personal burnout and work-related burnout as the dependent variables, and sleep duration as the independent variable. The mediator variable used the Taiwanese Depression Questionnaire to measure mental health. After literature review, gender, age, BMI (Body Mass Index) and workplace as the control variables are controlled. SPSS version 21 was used to analyze the data, and SOBEL was used to verify the mediating relationships. This study is a cross-sectional study and primary data.Results:The results of the mediation model validation showed mental health had a ‘partial mediating effect’ between sleep duration and burnout.Therefore, mental health can be regarded as a personal resource and an important factor affecting burnout that cannot be ignored.Conclusion and Suggestions:It can be verified that this mediating effect and influence model are established for blue-collar cleaners. In the future, the scholars in workplace safety should be with this framework to verify that different industries or white-collar workers work in different jobs, and then understand the differences in this model in different industries and work fields. Furthermore, it is looked forward to provide a basis of improving workplace health promotion and improving working conditions
