Childhood Trauma, Mentalization and Obsessive Compulsive Symptoms in a Non-Clinical Sample: A Mediation Analysis Study.

Objective: Obsessive and compulsive symptoms (OCS) are cross-cutting psychopathological manifestations frequently detected in a variety of clinical and non-clinical samples. It has been suggested that impaired mentalization abilities and traumatic experiences during childhood may be relevant etiopathogenetic factors in the development of OCS. The purpose of the current study was to cross-sectionally assess these variables in a non-clinical sample, testing the mediational role of mentalization abilities in the association between childhood trauma (CT) and OCS. Method: 667 participants (488 females; mean age= 29.76 ± 11.87 years; age range: 18-80) answered a survey including the Childhood Trauma Questionnaire, the Mentalization Questionnaire and the Obsession-Compulsion subscale of the Brief Symptom Inventory. Results: The mediation model was significant for the total effect (p< .001), showing that CT was positively associated with OCS (95% CI: .006; .019) and that this association was mediated by reduced levels of mentalization capacity (95% CI: .003; .009). Such results were significant controlling for potential sociodemographic and clinical confounding variables. Conclusions: The findings contribute to elucidate the complex relationships between CT, mentalization capacity, and OCS, supporting the possibility that mentalization impairments, arising from CT, may affect top-down control mechanisms thus contributing to the development of OCS.

Problematic use of Internet in a sample of psychiatric outpatients: preliminary observations from the "real world".

OBJECTIVE: This study aims to explore the prevalence, characteristics, and psychopathology related to Problematic Use of Internet (PUI), including Internet Addiction (IA), within a sample of psychiatric outpatients. METHODS: 143 psychiatric stable outpatients (18-65, mean age: 49; F=84) were included in this study, regardless of their categorical diagnosis. Socio-demographic, clinical, psychopathological, and Internet use-related data (PIU-Scale, Internet Addiction Test, devices, use, activities) were collected across the sample. RESULTS: The prevalence of PUI ranged between 1% (IAT) and 25% (PIU-S), with a homogeneous distribution of PUI symptoms' severity among the four main psychopathological areas (depressive, bipolar, anxiety, and psychotic disorders). PUI was correlated with age and was higher in students as in the general population. Significant associations were found between PUI symptoms and both personality and eating disorders; PUI was also positively correlated with the presence of other addictions (e.g., alcohol and/or substances). A greater proportion of patients with PUI presented other forms of behavioural addiction compared to non-symptomatic patients. Social media and online shopping, as well as video-streaming, resulted to be the main forms of PUI among patients with problematic use of the Internet. DISCUSSION: More studies are required among students diagnosed with eating and personality disorders. The association between PUI and other addictive disorders would support the hypothesis of their common shared pathophysiology. CONCLUSION: Healthcare providers and educators should be made aware of such risks. More studies are needed to confirm such preliminary findings.
