The aims of this study were to investigate the dentists' job-related stress using the newly developed Dentist Job Stress (DJS) questionnaire, and to explore the relationships among sociodemographic factors, job stress and mental health indicators, including psychosocial stress, depression, anxiety and sleep among Korean dentists.
An online survey including 1,520 dentists was conducted using the Brief Encounter Psychological Instrument-Korean version (BEPSI-K), the Center for Epidemiologic Studies Depression Scale (CES-D), the State-Trait Anxiety Index (STAI) and the Pittsburgh Sleep Quality Index (PSQI).
The response rate was 15.2% (n = 231). The DJS questionnaire consisted of environmental and vocational factors, and Cronbach's α coefficient was 0.69. Dentists' job stress was significantly associated with income (P = 0.0230), work time (P = 0.0009) and job satisfaction (P < 0.0001). A bivariate correlation study revealed that the BEPSI-K, CES-D, STAI-S and PSQI exhibited a significant correlation with the DJS scale. Multiple regression analysis found that depression, job satisfaction and sleep quality were associated with dentists' job stress, and this model accounted for 37.9% of the variation in the DJS scale (P < 0.0001).
The findings of this study revealed that the DJS questionnaire showed acceptable validity and reliability, and dentists' job stress was associated with depression, job satisfaction and sleep quality. The major implication of this study is that a stress-management programme focusing on practical ways to improve the mental health status and job satisfaction of dentists is critical to the reduction of occupational stress among Korean dentists.
本研究旨在使用新开发的牙医工作压力量表（DJS）调查牙医的工作相关压力，并探讨社会人口统计学因素、工作压力与心理健康指标（包括心理社会压力、抑郁、焦虑和睡眠）之间的关系，这些指标在韩国牙医中存在。
采用简短的心理工具-韩国版（BEPSI-K）、抑郁量表（CES-D）、状态-特质焦虑量表（STAI）和匹兹堡睡眠质量指数（PSQI），对 1520 名牙医进行了在线调查。
应答率为 15.2%（n=231）。DJS 问卷由环境和职业因素组成，Cronbach's α 系数为 0.69。牙医的工作压力与收入（P=0.0230）、工作时间（P=0.0009）和工作满意度（P<0.0001）显著相关。双变量相关研究表明，BEPSI-K、CES-D、STAI-S 和 PSQI 与 DJS 量表显著相关。多元回归分析发现，抑郁、工作满意度和睡眠质量与牙医的工作压力有关，该模型解释了 DJS 量表 37.9%的变异（P<0.0001）。
本研究结果表明，DJS 问卷具有良好的效度和信度，牙医的工作压力与抑郁、工作满意度和睡眠质量有关。本研究的主要意义是，针对改善牙医心理健康状况和工作满意度的实用方法，开展压力管理方案，对减少韩国牙医的职业压力至关重要。
