<p>This study investigates psychological stress among lower-ranking police personnel (constables) in the Bangladesh police force and explores how personality traits and coping strategies contribute to stress development. This exploratory research used a quantitative methodology to examine the exposure of constables to various psychological stressors. The study utilized a sample size of 174 constables from 16 police stations of the Chattogram Metropolitan Police (CMP). The findings indicate that constables exhibiting extraversion personality traits experience lower levels of psychological stress and employ problem-focused coping strategies to manage stressors. Conversely, constables exhibiting neuroticism and psychoticism traits tend to experience higher levels of psychological stress and utilize emotion-focused and avoidant coping strategies to defend against stressors. Finally, the study finds that there is a significant impact of personality traits and coping strategies in developing psychological stress among constables.</p>
