Daily use, especially of high-potency cannabis, drives the earlier onset of psychosis in cannabis users.
2013
UNLABELLED: Cannabis use is associated with an earlier age of onset of psychosis (AOP). However, the reasons for this remain debated. METHODS: We applied a Cox proportional hazards model to 410 first-episode psychosis patients to investigate the association between gender, patterns of cannabis use, and AOP. RESULTS: Patients with a history of cannabis use presented with their first episode of psychosis at a younger age (mean years = 28.2, SD = 8.0; median years = 27.1) than those who never used cannabis (mean years = 31.4, SD = 9.9; median years = 30.0; hazard ratio [HR] = 1.42; 95% CI: 1.16-1.74; P < .001). This association remained significant after controlling for gender (HR = 1.39; 95% …
Sociodemographic and psychological correlates of COVID-19 vaccine hesitancy and resistance in the young adult population in Italy.
2021
Background: Previous research has shown that young adults are more hesitant/resistant to COVID-19 vaccine uptake than older age groups, although the factors underlying this tendency are still under debate. The current study aimed to identify the sociodemographic and psychological correlates of vaccine hesitancy and resistance among young adults (18–40 years) during the nationwide COVID-19 vaccination campaign in Italy, the first country after China being hit by the pandemic and which suffered a large number of fatalities. Methods: This is a cross-sectional, web-based study conducted in Italy using an ISO-certified international survey company (respondi.com). Data were collected on 1200 part…
Environmental Dysfunctions, Childhood Maltreatment and Women’s Intimate Partner Violence Victimization
2017
International audience; Childhood maltreatment is considered a crucial explanatory variable for intimate partner violence (IPV) in adulthood. However, a developmental multifactorial model for the etiology of IPV is not shared by researchers yet. This study has investigated the role of a wide range of childhood maltreatments and family and social dysfunctions in predicting IPV; furthermore, it tests a model where childhood maltreatment mediates the relationship between environmental dysfunctions and IPV. The sample included 78 women: IPV (38) and non-IPV (40). The Italian version of the Childhood Experience of Care and Abuse (CECA) Interview was used to assess the presence of adverse childho…
Spatiotemporal Neurodynamics Underlying Internally and Externally Driven Temporal Prediction: A High Spatial Resolution ERP Study
2015
Abstract Temporal prediction (TP) is a flexible and dynamic cognitive ability. Depending on the internal or external nature of information exploited to generate TP, distinct cognitive and brain mechanisms are engaged with the same final goal of reducing uncertainty about the future. In this study, we investigated the specific brain mechanisms involved in internally and externally driven TP. To this end, we employed an experimental paradigm purposely designed to elicit and compare externally and internally driven TP and a combined approach based on the application of a distributed source reconstruction modeling on a high spatial resolution electrophysiological data array. Specific spatiotemp…
Combining tDCS with prismatic adaptation for non-invasive neuromodulation of the motor cortex
2017
Abstract Background Prismatic adaptation (PA) shifts visual field laterally and induces lateralized deviations of spatial attention. Recently, it has been suggested that prismatic goggles are also able to modulate brain excitability, with cognitive after-effects documented even in tasks not necessarily spatial in nature. Objective The aim of the present study was to test whether neuromodulatory effects obtained from tDCS and prismatic goggles could interact and induce homeostatic changes in corticospinal excitability. Methods Thirty-four subjects were submitted to single-pulse transcranial magnetic stimulation (TMS) over the right primary motor cortex to measure Input-Output (IO) curve as a…
Emotional expression and coping style in female breast cancer.
2007
Background: The study of the relationship of emotional status and tumor etiology has been investigated in order to elaborate a multifactorial model able to provide an answer integrating the different disciplines on cancer. The aim of this work is to investigate the knowledge on the alexithymia construct, exploring the presence of such trait in women affected by mammary carcinoma and analyzing the used coping strategies. The study has also examined personal thoughts related to event control (locus of control). Method: The Toronto Alexithymia Scale, Coping Orientation to Problems Experienced, and Locus of Control questionnaires were administered to a group of 86 women aged 31-55 years (mean =…
Attachment anxiety and avoidance and perceptions of group climate: an actor-partner interdependence analysis.
2012
There is a lack of research examining group members’ attachment styles and group climate perceptions in the context of the attachment styles and group climate perceptions of the other group members. In the current study, the actor–partner interdependence model (APIM) was used to examine the relationships among (a) a group member’s attachment pattern, (b) the aggregated attachment patterns of the other group members, (c) a group member’s perceptions of the group’s climate, and (d) the aggregated group climate perceptions of the other group members. One hundred ten Italian graduate students in six 10-session interpersonal growth groups were studied. Group members filled out the Attachment Sty…
Cross-Country Measurement Invariance and Effects of Sociodemographic Factors on Body Weight and Shape Concern-Related Constructs in Eight Countries.
2020
The aim of this study was to examine the cross-country invariance of five well-established measures of body weight and shape concern-related attitudes and behaviors (i.e., drive for leanness, drive for muscularity, strategies to increase muscle, strategies to lose weight, and weight and shape concerns). A secondary objective was to examine the effects of several sociodemographic factors (age, BMI, socioeconomic status, and gender) on item and latent factor scores of these constructs. A total of 6272 emerging adults (4218 women; Mage = 21.46, SD = 3.11) from Australia, Belgium, Canada, China, Italy, Japan, Spain, and the U.S. completed a self-report online survey as part of a larger study. O…
Assessing positive body image, body satisfaction, weight bias, and appearance comparison in emerging adults: A cross-validation study across eight co…
2020
Positive body image refers to individuals' ability to conceptualize their bodies with love, respect, and appreciation. The study of positive body image is relatively new, and instruments used to investigate this multi-faceted construct have received limited use in non-English speaking countries. Thus, the aim of this investigation is to consider four measures that are associated with positive body image across eight different countries. Participants (n = 6272) completed the Body Appreciation Scale-2, the Body Areas Satisfaction Scale, the Physical Appearance Comparison Scale, and the Weight Bias Internalization Scale. Multi-group confirmatory factor analyses (MG-CFAs) and item-response theo…
Personal conceptions of intelligence, self-esteem, and school achievement in Italian and Portuguese students.
2007
Educational research places emphasis on the fact that different cultures have different self-construals. These construals can influence cognitive, emotional, and motivational processes in individuals. Great importance is attached to individuals' implicit conceptions of the nature of their intelligence (incremental or entity) and self-esteem. In general, both representation of intelligence and self-esteem seem to play an important role in scholastic performance in terms of both a predispostion to learning and the results actually achieved. The aim of this research is to determine the relationship between variables such as school, and socioeconomic level and gender in Italian and Portuguese s…
