RESUMEN
Perfectionism is linked to a variety of mental health conditions in university students. Guided by the Perfectionism Social Disconnection Model, the purpose of the current mixed methods feasibility study was to evaluate the acceptability and potential effectiveness of a brief online intervention designed to reduce the negative consequences of perfectionism in university students. Seventy university students (83.9% female; M age = 19) reporting moderate to extreme levels of perfectionism completed the two hour 'Intentional Imperfection Program' (IIP). The IIP includes techniques to increase mindfulness, compassion for self and others, distress tolerance, and social skills. Participants completed self-report measures at baseline and at a two-week follow-up. Quantitative data showed statistically significant small to moderate reductions in self-oriented perfectionism (d = -0.48, p < .001), socially-prescribed perfectionism (d = 0.40, p < .001), hostility (r = 0.53, p < .001), rejection sensitivity (d = 0.37, p < .001), depression (r = -0.47, p < .001), and anxiety (r = -0.33, p = .010) and a small increase in perceived social support (r = -0.29, p = .023). Thematic analyses of qualitative data indicated that participants found the IIP feasible, enjoyable, and useful. A brief online intervention may be a feasible way of reducing the negative consequences of perfectionism among university students. A randomised control trial is warranted to further evaluate the efficacy of the IIP. This research was registered with the Australian New Zealand Clinical Trials Registry (no. ACTRN12620000574943).
