Psychological Effects of Professional Exposure to Trauma and Human Suffering: Systematic Review and Meta-Analysis

Over the past decades, a growing interest has emerged toward understanding the impact that the exposure to human suffering produces in mental health professionals, leading to the identification of three constructs: vicarious traumatization (VT), compassion fatigue (CF), and secondary trauma (ST). However, little is known about how these conditions affect psychologists. A systematic review and a meta-analysis were conducted to examine the evidence about the effects of occupational exposure to trauma and suffering in studies that included psychologists among their samples. Fifty-two studies were included comprising 10,233 participants. Overall, the results showed that most professionals did not experience relevant distress due to their work, yet some of them developed clinically significant symptoms (i.e., PTSD). However, solid conclusions could not be drawn due to the numerous methodological difficulties found in this research field (i.e., group heterogeneity, lack of comparison groups, and conceptual overlap). Thus, it is necessary to further investigate this topic with scientific rigor to understand these stressors and develop evidence-based interventions.
