Cannabis use and suicidal behaviours in high-school students.

The aim of the study was to evaluate the relative contributions of cannabis use, depressive and anxious symptoms in the prediction of suicidal behaviors. Participants were 248 high-school students who completed questionnaires assessing cannabis use, suicidal behaviors, depressive and anxious symptoms. Cannabis use was a significant independent predictor of suicidal behaviors after adjustment for depressive and anxious symptoms.

Relative contributions of acculturation and psychopathological factors to cannabis use among adolescents from migrant parents

Immigrant adolescents and adolescents born of immigrant parents are at increased risk of substance use which has been linked to difficulties in acculturation processes. However very few studies have examined the role of the different acculturation strategies and none of them have controlled for relevant psychopathological and socio-familial factors. The aim of this study was to investigate the role of acculturation in cannabis use in a sample of adolescents born of immigrant parents taking into account potential confounding variables. A sample of 292 high school students born in France from at least one foreign parent completed a questionnaire assessing cannabis use, acculturation orientations, ethnic identity and the most relevant potential confounders (depressive symptoms, sensation seeking, borderline and psychopathic traits, alcohol and tobacco use, parental attachment, life events, socioeconomic status and academic achievement). A regression analysis showed that acculturation orientations and ethnic identity explained a significant part of the variance in the frequency of cannabis use. Individualism, integration and assimilation were negatively associated with the frequency of cannabis use suggesting they might serve as protective factors.

Psychopathology of Online Poker Players: Review of Literature

Background and aims Online Texas Hold’em poker has become a spectacular form of entertainment in our society, and the number of people who use this form of gambling is increasing. It seems that online poker activity challenges existing theoretical concepts about problem gambling behaviors. The purpose of this literature review is to provide a current overview about the population of online poker players. Methods To be selected, articles had to focus on psychopathology in a sample of online poker players, be written in English or French, and be published before November 2015. A total of 17 relevant studies were identified. Results In this population, the proportion of problematic gamblers was higher than in other forms of gambling. Several factors predicting excessive gambling were identified such as stress, internal attribution, dissociation, boredom, negative emotions, irrational beliefs, anxiety, and impulsivity. The population of online poker players is largely heterogeneous, with experimental players forming a specific group. Finally, the validity of the tools used to measure excessive or problematic gambling and irrational beliefs are not suitable for assessing online poker activity. Discussion and conclusions Future studies need to confirm previous findings in the literature of online poker games. Given that skills are important in poker playing, skill development in the frames of excessive use of online poker should be explored more in depth, particularly regarding poker experience and loss chasing. Future research should focus on skills, self-regulation, and psychopathology of online poker players.

PsychopathologieInfluence de la consommation de cannabis sur les idées suicidaires chez 491 adolescents scolarisésInfluence of cannabis use on suicidal ideations among 491 high-school students

OBJECTIVE The aim of the study was to evaluate the relative contributions of cannabis use and depressive symptoms in the prediction of suicidal ideation. METHOD A random sample of 491 high-school students from the department of Haute-Garonne, France (290 girls, mean age=16.6+/-1.4; 201 boys, mean age=17.3 years+/-1.6) completed a questionnaire assessing cannabis use, the CES-D (center for epidemiological studies-depression scale) completed by the three-item sub-scale measuring suicidal ideation proposed by Garrison et al. (J Am Acad Child Adolesc Psychiatry 30 (1991) 636-641). RESULTS In the total sample, 15% of girls (n=44) and 23% of boys (n=46) reported having used cannabis at least once a month during the last three months. The mean CES-D score for girls was significantly higher than for boys (20.6+/-11 versus 18.4+/-10.9, t=2.4, p=0.01). According to the cut-off score of 24, 22% of boys and 36% of girls exhibited a moderate to severe depressive symptomatology (p=0.02). The mean suicidal ideation score was not significantly higher in girls than in boys (1.3+/-2 versus 0.95+/-1.9, t=1.7, p=0.10). At least, the occasional wish to kill oneself was reported by 17% of boys and 20% of girls (p=0.40). The contribution of cannabis use and depressive symptomatology in the prediction of suicidal ideation were tested with a hierarchical multiple regression analysis, to determine whether cannabis use improved prediction of suicidal ideation beyond that afforded by CES-D scores. In the first step, including age and sex as covariates, the model accounted for a significant and important part of the variance of suicidal ideation (41%). Age and sex were not significant predictors. The second step, with cannabis use added to the prediction of suicidal ideation, afforded an increase of 1% in predictable variance. Cannabis use (beta=0.08, t=2.2, p=0.03) was significantly but weakly related to suicidal ideation, while depressive symptoms (beta=0.63, t=17.8, p<0.001) remained the main predictor. In a second regression analysis conducted among cannabis users, frequency of use was almost a significant predictor (beta=0.11, t=1.84, p=0.07). DISCUSSION This result suggests an association between suicidal ideation, depressive symptoms and cannabis use in adolescents. Cannabis use appeared to be an independent predictor of suicidal ideation after controlling for depressive symptoms. However, the increment of variance accounted for by cannabis use was small. This suggests that cannabis use contributes to suicidal ideation independently from depressive symptoms, but weakly. A limitation to the study was the absence of control for other potential confounding variables. The association between cannabis use and suicidal ideation may be linked to common risk factors such as borderline personality disorder traits, sociodemographic and family factors. In this study, cannabis use does not appear as an important risk factor for suicidal ideation in adolescents.

Orientations d’acculturation et adaptation psychosociale des adolescents issus de l’immigration

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.

Validation of the French Version of the Marijuana Craving Questionnaire (MCQ) Generates a Two-Factor Model

Abstract Background: Craving is a major issue in drug addiction, and a target for drug treatment. The Marijuana Craving Questionnaire-Short Form (MCQ-SF) is a useful tool for assessing cannabis craving in clinical and research settings. Objective: To validate the French version of the MCQ-SF (FMCQ-SF). Methods: Young adult cannabis users not seeking treatment (n = 679) completed the FMCQ-SF and questionnaires assessing their frequency of cannabis use and craving, cannabis use disorder criteria, and alcohol use. Results: Confirmatory factor analysis of the four-factor FMCQ-SF model did not fit the data well. Exploratory factor analysis suggested a two-factor solution (“pleasure”, characterized by planning and expectation of positive effects, and “release of tension”, characterized by relief from anxiety, nervousness, or tension) with good psychometric properties. This two-factor model showed good internal and convergent validity and correlated with cannabis abuse and dependence and with frequency of cannabis use and craving. Conclusion: Validation of the FMCQ-SF generated a two-factor model, different from the four-factor solution generated in English language studies. Considering that craving plays an important role in withdrawal and relapse, this questionnaire should be useful for French-language addiction professionals.
