| Abstract: | Investigated the degree of absolute change, affective state dependence, and relative trait stability of several dimensions of perfectionism assessed by two popular, multidimensional measures. The study sample was 105 adult outpatients from a university hospital mood disorders program who met diagnostic criteria for major depressive episode at Time 1 and did not meet criteria for major depressive episode one year later (Time 2). Mean total scores on the Beck Depression Inventory decreased by almost 50% (from 28 to 15). Absolute change on perfectionism indices was smaller but significant for some maladaptive dimensions. Correlational, regression, and path analyses all indicated the presence of affective state dependence for several maladaptive dimensions of perfectionism (e.g., concern over mistakes, socially prescribed perfectionism). However, in all cases strong evidence was also found for the enduring trait stability of these dimensions. The results support a state-trait conceptualization of maladaptive perfectionism dimensions, which denotes stable individual difference variables that are elevated in the depressive state. Adaptive aspects of perfectionism showed little or no evidence of affective state dependence, consistent with findings from other research.
