Introduction: Psychological well-being is one of the main criteria of mental health and has an important role in the occupational world. Police as a profession has working guidelines that are potentially violated if the psychological well-being of the police is disrupted. The police profession is also closely related to high stress. Stress coping mechanisms and personality types of each police can affect the ability to deal with stress and overall psychological well-being. This study aims to examine the effect of stress and introverted personalities on psychological well-being through mediators of stress coping amongst policemen/-women. Methods: This study is a structural analysis research. Research participants in this study were policemen/-women belonging to Metro Jaya Regional Police group with recorded violations. The four variables tested in this study were stress and introverted personality (exogenous variables), psychological well-being (endogenous variables), and stress coping mechanism (mediator variables). Data collection for the four variables was carried out using the questionnaire filling method with a Likert scale. Analysis of data and hypotheses was carried out using SEM using the Lisrel 8.70 and SPSS 23.00 statistical programs for Windows. Results and Conclusion: The total number of research participants was 277 people, consisting of men (87.7%) and women (12.3%). Most of the respondents were aged 20 to 30 years (102 people) and as many as 52.3% of respondents were Bintara. More than half of the respondents (55.3%) have been working for less than 10 years. The theoretical model of the influence of stress and introverted personality on psychological well-being through stress coping mediators was found to be suitable with empirical data on the Indonesian National Police. There is a positive effect of stress coping on psychological well-being. There is no negative effect of stress or introverted personality on psychological well-being. There are negative effects of stress and introverted personalities on stress coping and psychological well-being with stress coping as a mediator.
