Maladaptive perfectionism has been associated with certain mental health problems. Moreover, studies suggest that the development of perfectionism can be attributed to childhood experiences and, more specifically, to parenting styles. (1) Background: The aims of the present study were first to examine the relationship of perfectionism to perceived parenting and current symptoms of depression and anxiety and, secondly, to study the effectiveness of a group CBT intervention program for high perfectionism; (2) Methods: Participants were 81 young Greek adults with relatively high scores in perfectionism. They were randomly allocated to two conditions: either the intervention group (IG; n = 40) or a non-active control group (CG; n = 41). The intervention group received a CBT intervention of 10 weekly sessions, while assessments were made in two time points for both groups; (3) Results: There was significant correlation of perfectionism with perceived parental indifference, abuse, and overcontrol as well as measures of anxiety and depression. Results showed significant decrease in perfectionism and other symptoms in the IG. Although perceived paternal indifference and abuse could predict perfectionism at pre-intervention, no pre-intervention variable could predict the perfectionism intervention outcome; (4) Conclusions: Overall, the study suggests that maladaptive perfectionism is associated with perceived negative parenting and current anxiety and depression and that a group CBT intervention can address specific dimensions of maladaptive perfectionism.

Obsessive-Compulsive Inventory-Revised (OCI-R) is a self-report questionnaire that assesses the distress caused by a variety of OCD symptoms; OCI-R comprises of 18 items that are equally divided into six subscales: Checking, Washing, Obsessing, Neutralization, Ordering, and Hoarding. Research so far has shown that OCI-R is a psychometrically sound measure with excellent validity and reliability. It is also appropriate for clinical and non-clinical populations and has been translated into several languages and has been validated in diverse cultural contexts. The aim of the present study was to validate OCI-R in the Greek language and to examine its psychometric properties in a Greek non-clinical sample. Three hundred and seventy one university students participated in this study. Measures used were OCI-R, the Padua Inventory (PI), the Obsessive Beliefs Questionnaire-44 (OBQ-44), and the Depression Anxiety Stress Scale (DASS-21). Consequent analysis of collected data examined the factor structure of OCI-R and tested its convergent and divergent validity. The confirmatory factor analysis showed good fit for the model and replicated the results of other studies, meeting thus the requirements for the six-factor solution of the original scale. The Greek version of OCI-R maintained the good psychometric properties of the original English one. Internal consistency was excellent for the overall scale. Convergent and divergent validity was good and also confirmed previous similar findings.

Intolerance of Uncertainty (IU) is described as the tendency to avoid uncertain states and exhibit negative responses to uncertain situations on cognitive, emotional, and behavioral levels. It is considered a transdiagnostic cognitive bias that plays a role in developing and maintaining psychopathology. The Intolerance of Uncertainty Scale-12 (IUS-12) has proven to be a sound measure of intolerance of uncertainty with excellent validity and reliability. Although research has supported a two-factor structure of IUS-12, most recent studies also suggest a bifactor model. The present study examines the factorial structure, validity, and reliability of the Greek version of IUS-12 with a sample of 959 university students (66.6% female) aged 19.63 years (SD = 3.20). Confirmatory Factor Analysis showed that although the two-factor solution adequately fit the data, the bifactor model better fit with IU total as an underlying one-factor. Internal consistency and validity were excellent for the total IUS-12 and Prospective and Inhibitory Anxiety subscales. Our findings support recent findings concerning the factorial structure of IUS-12 and the scale’s psychometric qualities in a Greek undergraduate sample. We expect that future research with clinical samples will confirm the screening and clinical utility of IUS-12.
