Abstract
(en) Perfectionism is a phenomenon that is gaining an increasing interest among researchers and health practitioners. However, no consensus currently exists concerning its definition, and there is still a lack of experimental and longitudinal studies. The purpose of this article is to shed light on this phenomenon using a process-based approach. As a first step, we introduce the theoretical and conceptual evolution of perfectionism. We distinguish between multidimensional conceptualizations and the cognitive-behavioural conceptualization of this construct. Across both, perfectionism is characterized by a cognitive and behavioural inflexibility. The latter maintains a functional impact and can lead to psychopathological disorders. In a second step, we review the psychological transdiagnostic processes of the first step conceptualizations, which underline inflexibility. We examine self-imposed personally demanding standards setting, evaluative concerns, self-criticism, dichotomous thinking, cognitive biases, ruminations, and experiential avoidance. We also briefly discuss the interpersonal consequences linked to perfectionism. As a third and final step, we outline clinical guidelines for targeting perfectionism within therapeutic treatments. We further detail the cognitive-behavioural treatment of Egan, Wade, Shafran, and Antony (2014) as it tackles the transdiagnostic processes of perfectionism and has received stronger empirical support.
