The National Healthcare Quality and Disparities report in 2022 revealed that almost a quarter of children ages 3-17 in the United States have a mental health related disorder. Because of this, well-equipped child therapists are needed to carry out the responsibility of providing services to support this population. However, several systematic reviews have noted the prevalence of burnout among therapists, possibly hindering quality care (Acker, 2010; Simionato & Simpson, 2018). Because of this, investigators have sought to understand burnout and its effect on child therapists. Many have noted the risks of professional burnout (Adams et al. 2006; Chen et al. 2019; Paris et al. 2010; Sanchez-Moreno et al., 2015), however there is limited research specific to burnout among child therapists. This study examined how self-efficacy, workload, and parent engagement interrelate with burnout among child therapists. A multiple regression analysis investigated relationships among self-efficacy, workload, and parent engagement with child therapist burnout (n=537). The findings indicate that the predictor variables explain 63% of the variance in child therapist burnout. Conditional process analyses were then employed to consider indirect and conditional relationships among the variables. Self-efficacy was found to moderate several relationships among parent engagement, workload, and burnout. Lastly, considerations, implications, and recommendations for future research are reviewed.
