OBJECTIVE The Depression Anxiety Stress Scales-21 (DASS-21) is the short version of a self-report measure that was originally developed to provide maximum differentiation between depressive and anxious symptoms. Despite encouraging evidence, the factor structure and other features of the DASS-21 are yet to be firmly established. METHOD A community sample(More)
The aim of the study was to evaluate psychometric properties of the Obsessive Compulsive Inventory (OCI) on Italian community and clinical samples. The Italian version of the 42-item OCI was administered to a sample of 340 individuals belonging to the general population and to 88 patients with obsessive compulsive (OCD) or other anxiety disorders. Four(More)
Fear of contamination within obsessive compulsive disorder (OCD) is traditionally conceptualized as a physical phenomenon. Research has also supported the notion of mental contamination (MC), in which people feel contaminated in the absence of contact with a physical pollutant. In the last decades, a growing number of studies has been centered on the role(More)
BACKGROUND Hoarding is associated with significant impairment. Although traditionally considered as a symptom of obsessive-compulsive disorder (OCD), some authors have proposed that pathological hoarding could be considered as a stand alone condition. The prevalence of pathological hoarding behaviour has been shown to be high in some countries, but little(More)
UNLABELLED Cognitive-behavioural models have linked unacceptable or repugnant thoughts in obsessive-compulsive disorder (OCD) with vulnerable self-themes and fear-of-self concerns. To investigate this notion, Aardema and coworkers recently developed and validated the Fear of Self-Questionnaire (FSQ) in non-clinical samples, finding it had strong internal(More)
The relationship between disgust propensity (DP) and obsessive–compulsive disorder (OCD), particularly with contamination-related OCD symptoms, has been widely recognized. The relationship between trait guilt (TG) and OCD has been less investigated, although some studies have explored the role of guilt in OCD, and found that it may precede, motivate or be a(More)
OBJECTIVE The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) is the most widely accepted measure of obsessive-compulsive disorder (OCD) symptom severity. Recently, the scale has been revised into a second edition (Y-BOCS-II) in order to improve its measurement properties. The present study aimed to evaluate the psychometric properties of the Italian version(More)
Contamination fear has always been considered a homogeneous symptom dimension. Compensatory behaviors (e.g., washing) are considered attempts to remove the contagion and to protect the individual from threats of illness; however, they may also be motivated by feelings of distress that are unrelated to any perceived harmful outcome, such as the feeling of(More)
OBJECTIVE The Vancouver Obsessional Compulsive Inventory-Mental Contamination Scale (VOCI-MC) is a self-report instrument that assesses symptoms of mental contamination. The aim of this study was to investigate the psychometric properties of the Italian version of the VOCI-MC in non-clinical and clinical samples. METHOD Factor structure, internal(More)
BACKGROUND The Vancouver Obsessive Compulsive Inventory (VOCI) is a self-report measure of the severity of obsessive-compulsive problems such as contamination, checking, obsessions, hoarding, needing things to be just right, and indecisiveness. In the seminal paper a six-correlated-factor structure was found in a sample of OC patients, but the issue of the(More)
