Perfectionism cognitions capture automatic perfectionistic thoughts and have explained variance in psychological adjustment and maladjustment beyond trait perfectionism. The aim of the present research was to investigate whether a multidimensional assessment of perfectionism cognitions has advantages over a unidimensional assessment. To this aim, we examined in a sample of 324 university students how the Perfectionism Cognitions Inventory (PCI) and the Multidimensional Perfectionism Cognitions Inventory (MPCI) explained variance in positive affect, negative affect, and depressive symptoms when factor or subscale scores were used as predictors compared to total scores. Results showed that a multidimensional assessment (PCI factor scores, MPCI subscale scores) explained more variance than a unidimensional assessment (PCI and MPCI total scores) because, when the different dimensions were entered simultaneously as predictors, perfectionistic strivings cognitions and perfectionistic concerns cognitions acted as mutual suppressors thereby increasing each others' predictive validity. With this, the present findings provide evidence that--regardless of whether the PCI or the MPCI is used--a multidimensional assessment of perfectionism cognitions has advantages over a unidimensional assessment in explaining variance in psychological adjustment and maladjustment.

has been linked to psychopathology but can have both positive and negative elements. The purpose of the present study is to examine whether the relationship of SOP to positive and negative affect would be mediated by the presence of specific cognitions regarding "Personal Standards (PS)," and "Concern over Mistakes (CM)" as well as goal motivations. Two mediations involved in SOP were hypothesized: (1) in the presence of approach goals, the cognition of PS emerges from activated SOP and leads to positive affect; and (2) in the presence of avoidant goals, the cognition of CM emerges from activated SOP and leads to negative affect. In Study 1, 358 college students completed the research questionnaire, and structural equation modeling was used to test the mediation model. In Study 2, 60 participants, 30 rated high and 30 rated low in SOP, were presented with either an approach or an avoidant goal for an experimental task, and asked to rate their perfectionism cognitions and affects. The findings provided partial support for the hypotheses.
