Effects of a Brief Mindfulness Intervention Program: Changes in Mindfulness and Self-Compassion Predict Increased Tolerance of Uncertainty in Trainee Psychologists

Clinical training can represent a time of great uncertainty for trainee psychologists. Existing research has identified a relationship between low tolerance of uncertainty and a range of negative physiological and psychological reactions, as well as an increased potential for burnout. We developed a mindfulness program to support trainees in their clinical training and proposed that increased mindfulness and self-compassion would support an increase in the tolerance of uncertainty experienced by trainees. Postgraduate psychology students who completed the 6-week mindfulness program as part of the curriculum were invited to participate in the study. Pre- and postintervention measures regarding mindfulness, self-compassion, and tolerance of uncertainty were completed (n = 98). Significant increases in the mindfulness facets of nonjudging, nonreacting, and observing as well as self-compassion were found, while a significant decrease in Uncertainty Reluctance to Disclose and Uncertainty Stress was also noted. Regression models revealed that the change in mindfulness facets nonjudging and nonreacting represented the largest effect on Uncertainty Reluctance to Disclose, while the change in self-compassion represented a smaller, significant effect. Nonjudging and self-compassion were found to have a marginal but not significant effect on Uncertainty Stress. Supporting trainee psychologists to tolerate the uncertainty inherent to clinical work is an important aspect of university training programs. Mindfulness programs can support student learning and potentially reduce burnout through the promotion of a nonjudging, nonreactive, and self-compassionate stance that may encourage trainees to disclose their uncertainty and seek support. Public Significance Statement This study highlights the role of mindfulness and self-compassion in increasing the tolerance of uncertainty in trainee psychologists. Findings support the inclusion of mindfulness programs in clinical training, to support students learning and potentially reduce burnout.
