The relationships between perfectionism, pathological worry and generalised anxiety disorder (GAD) were investigated in a clinical sample presenting for treatment of perfectionism. This study explored the utility of perfectionism in predicting pathological worry in a sample of individuals with elevated perfectionism and GAD (n = 36). Following this, the study examined whether perfectionism could predict a principal GAD diagnosis in the full sample (n = 42). Scores on the perfectionism dimensions Concern over Mistakes, Personal Standards, and Clinical Perfectionism significantly predicted pathological worry among participants with GAD after controlling for gender and depression. The perfectionism dimension Doubts about Actions significantly predicted whether individuals from the full sample received a principal diagnosis of GAD. These findings support certain dimensions of perfectionism having significant associations with pathological worry and GAD.
Background: Research indicates that psycho-education and cognitive behavioural interventions can reduce perfectionism but to date no group treatments have been examined. Aims: The current study utilized a case series design to compare psycho-education materials and subsequent eight-week group cognitive behaviour therapy (CBT) to a baseline waitlist in an outpatient community psychiatry sample ( n = 21). Method: Participants were assessed on five occasions: baseline, 4 weeks later (waitlist), 4 weeks after receiving psycho-education material, post-treatment (8 weeks after receiving the group intervention), and 3-month follow-up. Results: There was a main effect of time for perfectionism and negative affect from baseline to post-group (effect sizes ranging from 1.46 to 1.91) that were maintained at 3-month follow-up. Conclusions: These results suggested that group CBT for clinical perfectionism may be beneficial, but that psycho-education alone is not effective for reducing perfectionism or negative affect.
