Abstract

Summary: The view that perfectionists are prone to experiencing sleep disturbance is widely held. Yet, almost three decades of empirical research have yielded conflicting results. Whereas some researchers viewed perfectionism as a risk factor for sleep disturbance, others spoke of "adaptive" or "positive" forms of perfectionism in the context of sleep. The multidimensional conceptualisation of perfectionism may resolve this disagreement. Thus, this systematic review aimed to clarify the perfectionism‒sleep disturbance link using the widely accepted two‐dimensional perfectionism model, differentiating perfectionistic concerns (defined by worries over imperfections) and perfectionistic strivings (defined by excessively high personal standards). A systematic literature search returned 24 relevant empirical studies. Perfectionistic concerns were robustly linked to sleep disturbance. Perfectionistic strivings displayed comparatively small and inconsistent relations with sleep disturbance. Finally, cross‐sectional mediation studies suggested that psychological distress and dysfunctional cognitive processes might underlie the perfectionistic concerns‒sleep disturbance link. These findings show that considering perfectionistic concerns in explaining, predicting, and treating sleep disturbance may be a promising approach. In contrast, perfectionistic strivings appeared neither universally adaptive nor maladaptive. We identified several critical gaps in the empirical literature and point towards future research directions, highlighting the need for more longitudinal studies.
