![]() Our second aim is to evaluate the relationships between CE, quality of life, and different body concerns in a group of individuals. This study evaluates the psychometric properties of the Compulsive Exercise Test (CET), the questionnaire most frequently discussed in the literature. Implications for future clinical applications are discussed.Ĭompulsive exercise (CE) has been proposed as one of the maladaptive elements that might concur to developing and maintaining an eating disorder (ED), even if no conclusive consensus is yet available. Findings provide cross-sectional support for the role of IU as a transdiagnostic feature in predicting a wide range of anxiety disorder symptoms in youth. Furthermore, youth-reported prospective/inhibitory IU were significantly related to specific youth anxiety and related disorder symptoms including generalized anxiety, separation anxiety, physical injury fears, obsessive-compulsive, social anxiety and panic/agoraphobia disorder symptoms. Youth with higher scores on total IU and prospective/inhibitory IU dimensions had significantly higher levels of anxiety disorder symptoms. Significant associations were found between youth- and parent-report IU and youth anxiety disorder symptoms. The relationships between IU and anxiety disorder symptoms among youth with and without anxiety disorders, and their parents, were examined. The present study examined the role of intolerance of uncertainty (IU) in predicting the severity of anxiety disorder symptoms among a sample of Iranian youth. These results highlight the feasibility and utility of the SCID to assess reliable and valid symptom severity dimensions of both current and lifetime psychopathology.Īnxiety disorders are the most prevalent disorders among youth and understanding cognitive vulnerabilities for these disorders is crucial for early prevention and treatment. The psychometric properties of SCID-identified symptom scales were far superior to the psychometrics of categorical diagnoses for both current and lifetime psychopathology. Symptom severity scales demonstrated significant incremental validity over and above categorical diagnoses for both current and prospective outcomes. The SCID's severity scales demonstrated substantial internal consistency (all Cronbach's αs >.80), test–retest reliability, and concurrent and predictive validity. Dimensional severity scales were created from an adapted version of the SCID for both current and lifetime major depression, alcohol, substance, post-traumatic stress disorder, panic, agoraphobia, social anxiety, specific phobia, obsessive–compulsive disorder, and generalized anxiety disorder. Retest reliability and prospective predictive validity (symptoms and functioning 1 year later) were examined in subsamples of participants. Participants (N = 234) were recruited from the community and clinics. The present study also examined whether these severity dimensions have better psychometric properties (internal consistency, test–retest reliability, and concurrent and predictive validity) than categorical diagnoses. This study examined whether the Structured Clinical Interview for DSM (SCID), a widely used semistructured interview designed to assess psychopathology categorically, can be adapted to identify reliable and valid severity dimensions of psychopathology.
