Research is scarce regarding personality disorder traits of individuals with subclinical obsessive-compulsive symptoms. Cluster analysis based on obsessional, schizotypal, and borderline personality and autism-spectrum features was conducted on the results for 118 students scoring above cutoff on the Obsessive Compulsive Inventory-Revised. This identified four groups: O, L, S, and A. One third of the sample was represented by individuals with obsessional traits (O), while another third was composed of individuals with low traits (L); the last two profiles corresponded to a cluster with autistic traits (A) and a group with schizotypal and borderline features (S), both clusters together comprising the remaining third. Significant differences were observed between groups, both on personality traits and on psychopathological symptoms. The S cluster displayed the highest scores of suicidality, depression, and obsessive-compulsive symptoms. This study identified meaningful profiles of personality disorder traits, distinct from obsessive-compulsive personality, in individuals with subclinical obsessive-compulsive symptoms.

Objective: Food and Alcohol Disturbance (FAD), colloquially coined "drunkorexia," is a set of behaviors that encompasses restriction of calories, over-exercise, and other compensatory behaviors before, during, or after alcohol use to offset caloric intake or maximize intoxication. To date, this phenomenon has not been compared in a cross-cultural sample., Method: The Compensatory Eating and Behaviors Related to Alcohol Consumption Scale (CEBRACS), Eating Disorder Inventory - Drive for Thinness Subscale (EDI-DT) and Alcohol Use Disorders Identification Test of Consumption (AUDIT-C) were completed by 502 American (73% female) and 365 French (68% female) college students., Results: Just over half (56.70%) of French and American (55.83%) participants engaged in FAD. Nationality was found to be a significant moderator of the relationship between alcohol use and FAD for both compensatory (p = .013) and intoxication (p = .01) purposes, such that Americans who drank more engaged in more FAD. Further, nationality moderated the relationship between drive for thinness and FAD for compensatory purposes (p = .005), but not for intoxication purposes (p = .10). At higher levels of drive for thinness French participants were more likely to engage in FAD for compenatory purposes., Discussion: There is growing concern around how maladaptive eating and drinking behaviors intersect within the college population. These findings suggest that FAD is present cross-culturally, but that the relationships between predictors vary across culture. Thus, culture should be taken into consideration in the development of interventions for FAD., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

Aim: The literature has highlighted that strategies to increase appropriate and timely treatment seeking for eating disorders (EDs) are needed. The aim of this study was to use the Internet to disseminate guidelines for providing first aid to individuals suffering from ED among college students., Methods: Users were invited to complete two surveys: an initial one assessing user characteristics and, 28 days later, a questionnaire assessing the perceived usefulness of the guidelines. A sample of 651 college students (M age  = 22, standard deviation (SD) = 3.9) responded to the first questionnaire and 50 completed the second questionnaire (M age  = 22.2, SD = 2.6)., Results: The guidelines were downloaded 1174 times and 56% of users reported finding them useful., Conclusions: College students might be particularly interested in learning more about ED and the guidelines could be valuable to address the gap in available resources for ED-related mental health literacy., (© 2016 John Wiley & Sons Australia, Ltd.)

Personality traits are closely related to eating disorders (ED) and might be involved in their development and maintenance. Nevertheless little is known regarding the association between personality traits and disordered eating in subclinical populations. College students answered questionnaires assessing disordered eating behaviors (DEB) and the following personality disorder (PD) traits: schizotypal, autistic, obsessional, borderline and cyclothymic. Participants with DEB (n=101, 87% women) displayed significantly higher scores for several variables including schizotypy, cyclothymic, borderline and obsessional traits compared to other participants (n=378). Cluster analysis in the DEB subsample led to the identification of three groups: 1) a cluster with a high level of traits (HT); 2) a cluster scoring high on schizotypal, borderline and cyclothymic traits (SBC); 3) a cluster with a low level of traits (LT). Symptoms of depression, suicidal ideations, trait anger and obsessive-compulsive symptoms were higher in the HT and the SBC clusters compared to the LT cluster. Given that two thirds of participants suffering from DEB appeared to display a morbid personality profile, it appears of prime importance to take into account PD traits of individuals with DEB., (Copyright © 2016 Elsevier Ltd.

Objective: The purpose of this meta-analytic review was, first, to evaluate the efficacy of Internet-based programs in decreasing eating disorder (ED) symptoms, and, second, to identify moderator variables these effects., Method: Twenty studies were identified and between-group effect sizes were calculated for ED symptoms and risk factors., Results: Compared with control conditions, Internet-based programs successfully decreased body dissatisfaction (d = 0.28, 95% CI [0.15-0.41], p < .001), internalization of the thin ideal (d = 0.36, 95% CI [0.07-0.65], p < .05), shape and weight concern (d = 0.42, 95% CI [0.13-0.71], p < .05), dietary restriction (d = 0.36, 95% CI [0.23-0.49], p < .001), drive for thinness (d = 0.47, 95% CI [0.33-0.60], p < .001), bulimic symptoms (d = 0.31, 95% CI [0.20-0.41], p < .001), purging frequency (d = 0.30, 95% CI [0.02-0.57], p < .05), and negative affect (d = 0.32, 95% CI [0.12-0.52], p < .001). Moderator analyses revealed no impact of data analytic strategy on intervention effects. Similarly, participant risk status was not a moderator for most outcomes., Discussion: Internet-based programs are successful in decreasing ED symptoms and risk factors with small to moderate between-group effect sizes., (© 2015 Wiley Periodicals, Inc.)

Exposure to traditional media has been associated with bulimic symptoms. However, to date, little is known regarding the effects of Internet exposure. The aim of this study was to explore the relationships between Internet use and bulimic symptoms within the competing frameworks of sociocultural, impression management, and self-objectification theory. A sample of 289 French women aged 18-25 years completed an online questionnaire assessing bulimic symptoms, body dissatisfaction, body image avoidance, self-surveillance, body shame, and weekly Internet use. Bootstrapping analyses revealed that body shame and body image avoidance mediated the effect of weekly Internet use on bulimic symptoms. Furthermore, when entered into a multiple mediation analysis, these two variables provided independent mediation pathways of equal magnitude. The findings support the usefulness of both the self-objectification and impression management frameworks for investigating the relationship between Internet use and bulimic symptoms. Longitudinal research would help to clarify these pathways further.

Objective: The aim of the study was to explore the typology of adolescents with immigrant background based on the orientations of acculturation and to estimate the psychosocial adaptation of the various subtypes., Method: A sample of 228 French high school students with an immigrant background completed a questionnaire assessing acculturation orientations (Immigrant Acculturation Scale; Barrette et al., 2004), antisocial behaviors, depressive symptoms and self-esteem. Cluster analysis based on acculturation orientations was performed using the k-means method., Results: Cluster analysis produced four distinct acculturation profiles: bicultural (31%), separated (28%), marginalized (21%), and assimilated-individualistic (20%). Adolescents in the separated and marginalized clusters, both characterized by rejection of the host culture, reported higher levels of antisocial behavior. Depressive symptoms and self-esteem did not differ between clusters., Discussion: Several hypotheses may explain the association between separation and delinquency. First, separation and rejection of the host culture may lead to rebellious behavior such as delinquency. Conversely, delinquent behavior may provoke rejection or discrimination by peers or school, or legal sanctions that induce a reciprocal process of rejection of the host culture and separation. The relationship between separation and antisocial behavior may be bidirectional, each one reinforcing the other, resulting in a negative spiral. This study confirms the interest of the study of the orientations of acculturation in the understanding of the antisocial behavior of adolescents with immigrant background., (Copyright © 2014 L’Encéphale, Paris.

Background: There are few studies on the contribution of personality disorder traits to cannabis use disorders in adolescents., Objectives: The aim of the study was to evaluate the association of personality disorder traits to problematic cannabis use., Methods: Participants were 111 high school students who completed self-report questionnaires, mainly the Cannabis Use Disorders Identification Test, assessing problematic cannabis use, and the Personality Diagnostic Questionnaire using the scales evaluating personality disorders most often linked to adolescent cannabis use., Results: A multiple regression analysis showed that personality disorder traits explained a high part of the variance in problematic cannabis use symptoms. Schizotypal and borderline personality traits were positively associated to problematic cannabis use symptoms after adjustment for anxious and depressive symptoms., Conclusions: This study suggests the importance of evaluating personality disorder traits in studies of risk factors or consequences of problematic cannabis use.

Background: The association of cannabis use and suicidal ideations in adolescents has been inconsistent. This discrepancy may reflect differences in controlled confounders. In particular, no study has controlled for personality disorder traits linked to both cannabis use and suicidality such as borderline and psychopathic personality traits., Method: Participants were 972 high-school students who completed questionnaires assessing cannabis use, suicidal ideations, depressive symptoms, social anxiety symptoms, and borderline and psychopathic personality traits., Results: Cannabis use was not a significant independent predictor of suicidal ideations after adjustment for confounding personality traits in the total sample and in the subsample of cannabis users., (Copyright © 2014 Elsevier Ltd.

Objective: The aim of the study was to evaluate the contribution of cannabis to the prediction of delinquent behaviors., Method: Participants were 312 high-school students who completed self-report questionnaires measuring antisocial behaviors, the frequency of cannabis and alcohol use, psychopathic traits using the Youth Psychopathic traits Inventory, borderline traits, depressive symptoms, socio-economic status, life events, attachment to parents, and low academic achievement. Hierarchical multiple regression analyses were conducted to investigate the contribution of cannabis use and potential confounding variables to antisocial behaviors., Results: Boys reported a greater number of delinquent behaviors than girls (10.2±9.2 vs. 5.4±5.3, t=9.2, P<0.001). Thirty-seven percent of boys and 24 % of girls reported having used cannabis at least once during the last six months (P<0.001). Among cannabis users, boys reported a greater frequency of use than girls: average use for boys was 2-3 times per month whereas average use for girls was once a month (3.4±2.3 vs. 2.6±2, t=2.9, P=0.004). Cannabis users reported a greater number of antisocial behaviors than non-users (13.2±9.9 vs. 6.1±6.3, t=13.6, P<0.001). Multiple regression analyses showed that cannabis use was a significant independent predictor of antisocial behaviors in both gender (β=.35, P<.001 in boys, β=.29, P<.001 in girls) after adjustment for alcohol use, psychopathological and sociofamilial variables., Discussion: The unique and independent association between frequency of cannabis use and antisocial behaviors does not indicate the causal direction of the relationship. It may be that cannabis use induces antisocial behaviors by enhancing impulsivity or irritability or by the need for money to buy cannabis. Conversely, antisocial behaviors may lead to cannabis use either through becoming used to transgressions or through the influence of delinquent peers using cannabis. This link is probably bidirectional, cannabis use and antisocial behaviors influencing mutually in a negative interactive spiral. This association suggests that these two problems are to be jointly approached when treating adolescents using cannabis or having antisocial behaviors., (Copyright © 2014 L’Encéphale, Paris.

The objective of this study was to cross-sectionally explore the mediating role of self-serving cognitions in the relationship between antisocial behavior and psychopathic traits. A sample of 970 high school students completed self-report questionnaires assessing antisocial behavior, cognitive distortions, and psychopathic traits. Cognitive distortions partially mediated (and gender moderated) the relationship between antisocial behavior and psychopathic traits. Gender was found to moderate this relationship. Longitudinal studies would permit a fuller understanding of how these relationships interrelate-an understanding that may have important implications for clinical intervention.

Internet addiction is an increasing concern among young adults. Self-presentational theory posits that the Internet offers a context in which individuals are able to control their image. Little is known about body image and eating concerns among pathological Internet users. The aim of this study was to explore the association between Internet addiction symptoms, body image esteem, body image avoidance, and disordered eating. A sample of 392 French young adults (68 percent women) completed an online questionnaire assessing time spent online, Internet addiction symptoms, disordered eating, and body image avoidance. Fourteen men (11 percent) and 26 women (9.7 percent) reported Internet addiction. Body image avoidance was associated with Internet addiction symptoms among both genders. Controlling for body-mass index, Internet addiction symptoms, and body image avoidance were both significant predictors of disordered eating among women. These findings support the self-presentational theory of Internet addiction and suggest that body image avoidance is an important factor.
