There has been renewed interest in trauma and how it impacts an individual's quality of life and mental well-being. Research on trauma has shown that child maltreatment is linked to adverse long-term mental health consequences, including depression (Humphreys et al., 2020). There has been less research into how previous trauma affects the quality of life and mental well-being in critical, non-critical, and student samples. The present study aimed to explore the relationship between previous trauma and prevalent trauma and how this affects quality of life and mental well-being. An online survey provided quantitative data from 140 participants. The findings indicated that there was a non-significant relationship between levels of trauma in different occupations. There was a positive significant relationship between different levels of trauma and patient health. There was a significant relationship between patient health and quality of life and mental well-being and quality of life. By examining trauma, this research may assist in creating effective therapies and interventions for people dealing with mental health disorders such as PTSD, and depression. The findings may contribute to a better understanding of how trauma affects the general population.
