DescriptionRecent position papers have called for a focus on compassion in the training and practice of board certified behavior analysts (BCBAs; LeBlanc et al., 2020; Taylor et al., 2019). Much of this preliminary effort emphasizes the importance of compassion in behavior analysts’ work with families of individuals with autism and other developmental disabilities, highlighting research from other fields that demonstrates a relation between practitioner empathy and patient outcome. However, some research in burnout among applied behavior analysis (ABA) professionals indicates that supervisory relationships play important roles in the well-being of ABA professionals (Gibson et al., 2009). The current study will report on findings from a survey of 1,335 ABA providers that measured burnout, BCBA compassion, and BCBA engagement in 29 supervisory practices. Descriptive analyses highlighted staff perceptions of BCBAs’ engagement in each practice and perceived importance of technical versus compassionate practices. Findings revealed several supervisory practices that BCBAs are not currently engaging in regularly, notably the provision of learning opportunities and use of praise. A one-way ANOVA found statistically significant differences in burnout between job positions. Multiple regression and mediation analyses found that perceived supervisor support mediates the relationship between supervisor compassion and staff burnout. Qualitative analyses revealed that staff believe that factors related to work demands, organizational systems, staffing, client factors, and supervision contribute most to their burnout. Implications for the training of BCBAs in supervision and for behavior analytic organizations are discussed.
