Anorexia nervosa: Enhancing motivation to change with self-determination theory.

Motivational deficits (little or no motivation to change) are often reported in patients with eating disorders, particularly anorexia nervosa. The motivational approaches frequently used by French clinicians rely solely on a dichotomous view of motivation (intrinsic vs. extrinsic). In self-determination theory, certain forms of extrinsic motivation can strengthen an individual's commitment to an activity, providing they are self-determined. This theory therefore extends and enriches the dual motivational approach by highlighting potentially useful forms of extrinsic motivation and by emphasizing the importance of behavioral regulation. Empirical work is now needed to assess how clinicians can use self-determination theory to enhance motivation to change among patients with anorexia nervosa and encourage their adherence to care management plans.

The Role of Attentional Networks in Smoking Behavior Among Young Adults: Specific Contribution of Executive Control.

INTRODUCTION: The exploration of cognitive impairments associated with tobacco use disorder has expanded during the last decades, centrally showing working memory and executive deficits among smokers. Despite their critical role in everyday life and in the smoking cessation process, attentional abilities have seldom been explored. Previous studies yielded discordant results, and the involvement of attentional deficits in smoking habits remains unclear. AIMS AND METHODS: Capitalizing on the Attention Network Test, a theory-grounded task allowing the simultaneous but distinct evaluation of three attentional networks (alerting, orienting, executive control), we explored attentional abilities in three groups of 25 college students (nonsmokers, light smokers, heavy smokers), matched for demographic and psychopathological characteristics. RESULTS: While light smokers did not present any deficit compared with nonsmokers, heavy smokers showed a specific impairment of the executive control subcomponent of attention, contrasting with preserved alerting and orienting attentional abilities. The executive control deficit was not related to current craving or to smoking duration. CONCLUSIONS: Beyond the already explored memory and executive deficits, tobacco use disorder is associated with attentional impairments, characterized by a reduced ability to focus attentional resources on pertinent stimuli and resist to distractors interference. Given the assumed role of attentional impairments in smoking, our findings suggest that a critical step in future translational iterations is to develop neuropsychological rehabilitation programs tapping into the executive network of attention among smokers. IMPLICATIONS: This study clarifies the presence and extent of attentional impairments in tobacco use disorder. We measured three attention networks (alerting, orienting, executive control) in light smokers, heavy smokers and matched healthy controls through a theory-grounded task (Attention Network Test). Heavy smokers (but not light ones) present a specific deficit for the executive control of attention. This deficit, uncorrelated with psychopathological comorbidities or current craving, appears directly related to smoking. Given the currently scattered literature on this topic, attentional processes deserve a thorough audit in tobacco use disorder, notably to develop specific neurocognitive rehabilitation.

Reducing Attentional Bias in Individuals With Alcohol Use Disorders With a Tablet Application: A Randomized Controlled Trial Pilot Study.

AIMS: Cognitive bias modification (CBM) training has been considered a promising and effective intervention tool for reducing cognitive biases toward alcohol. However, the link between the cognitive process and actual behavior remains statistically insignificant because computerized tasks do not have sufficient ecological validity and suffer from high dropout rates. The recent development of 'serious games' has shown encouraging results in maintaining adherence to health-related interventions. We aim to evaluate a CBM program using a gamified attentional bias (AB) training procedure on a touchpad for individuals with alcohol use disorders. METHODS: Forty-one patients were included in this study, 33 of whom displayed an AB and were randomly assigned into the 'CBM group' (N = 18, 16.7% women) or 'Memory group'-which involved playing a memory game-(N = 15, no woman). Eight other participants (12.5% women) with no AB comprised the 'Without AB group'. Efficacy was assessed for AB, craving, and inhibition and attentional capacities before and after the program. RESULTS: We observed that the reduction of AB was higher for the 'CBM group' (Mbefore = 153.61, SD = 172.21; Mafter = 18.00, SD = 77.71; t (17) = 4.21, P = 0.001) than for the 'Memory group' (Mbefore = 73.20, SD = 66.65; Mafter =42.47, SD = 113.77; ts < 1). The analysis showed that for the 'Without AB group', there was no significant difference in AB (t (7) = -2.15, P = .07) after the program. CONCLUSIONS: This study demonstrated an increased reduction of AB for patients included in the CBM program on a touchpad than for patients playing only a memory game.

Craving Mediates the Relation Between Impulsivity and Alcohol Consumption Among University Students.

BACKGROUND AND OBJECTIVES: The relationship between impulsivity and craving in severe alcohol use disorders is well established, but the presence and characteristics of this link in University students are still to be established. The present study aims to better understand the relationship between impulsivity and craving in university students and to determine the influence of these variables on alcohol consumption characteristics. METHODS: A large sample of university students (N = 1055, mean age: 20.9 years; 713 women) completed an online questionnaire to evaluate alcohol use, impulsivity, and craving. RESULTS: Linear regression analysis demonstrated that the compulsive dimensions of craving (P < .001), sensation seeking (P < .001), and lack of premeditation (P < .001) constitute strong predictors of current consumption. A receiver operating characteristic (ROC) curve analysis determined the threshold level above which craving intensity can identify specific high-risk populations. A mediation analysis showed that craving has a partial mediator effect on the impact of impulsivity on alcohol consumption for this population (37,8%, P < .001). DISCUSSION AND CONCLUSIONS: The sensation seeking and lack of premeditation dimensions of impulsivity, coupled with compulsive craving, are efficient predictors of excessive alcohol consumption for university students. The partial mediator effect of craving is important in terms of characterizing the relationship between impulsivity and alcohol consumption. SCIENTIFIC SIGNIFICANCE: Our study centrally shows that the interaction between elevated levels of impulsivity and craving constitute a crucial risk factor for alcohol consumption in university students, and should thus constitute a target for primary prevention programs (Am J Addict 2019;00:00-00).

The calories underestimation of "organic" food: Exploring the impact of implicit evaluations.

Specific attributes of a food product can cause it to be spontaneously but wrongly perceived as healthier than it really is (i.e., the health halo effect). Notably, there is preliminary evidence that individuals evaluate organic food as less caloric than regular, non-organic food. However, explanations regarding the cognitive mechanisms underlying the health halo effect remain scarce. Drawing from the implicit cognition literature, we hypothesize that this effect could be due to (a) the reactivation in memory of implicit positive evaluations and/or (b) the reactivation of a semantic association between the concepts "organic" and "non-caloric". We first conducted a 2 (Product label: organic versus non-organic) × continuous (Valence-IAT score) × continuous (Calorie-IAT score) study (N = 151) to test these hypotheses, and conducted a conceptual replication in a second study (N = 269). We computed Bayesian analyses alongside frequentist analyses in order to test for potential null hypotheses, as well as frequencies and Bayesian meta-regression including both datasets. Both methods provided consistent results. First, Bayesian analyses yielded extremely strong evidence in favor of the hypothesis that the organic label leads to an underestimation of caloric value. Second, they provided strong evidence that this effect is not moderated by implicit evaluations. Hence, we replicated the organic halo effect but showed that, surprisingly, it does not arise from implicit associations. We discuss these findings and propose directions for future research regarding the mechanisms underlying calories (under)estimation.

Free-Will and Alcohol Consumption Impact on the Estimation of Responsibility on a Judgment Task.

Background and objectives: To which extent is a perpetrator responsible for an offense when he has (or not) consumed alcohol remains subject to conflicting results. Methods: In this study, participants (n = 162) were randomly asked to sentence a perpetrator for an assault in a nightclub (mild) and spousal violence (severe). In each case, the perpetrator was either sober or had consumed alcohol. Results: Our results show that participants judge the perpetrator less severely when he was an alcohol user, but only when the seriousness of the offense is mild. In both cases, the more participants believed in Free Will, the harsher the sentence. Conclusions and scientific significance: Methodological and implications of how individuals' beliefs may bias legal decisions are discussed.

Food-Cal: development of a controlled database of high and low calorie food matched with non-food pictures.

BACKGROUND: Industrialization has led to more varied and attractive high-calorie foods. Health problems such as obesity and diabetes are partially attributed to eating-related self-regulation difficulties that may be caused by increasingly frequent cues for highly palatable foods. Research studies aim at understanding the factors underlying responses to food cues. This has led to the development of food stimuli databases. However, they present some limitations. OBJECTIVES: This study aimed at providing a controlled set of pictures, including 40 food pictures with high- and low-calorie stimuli, matched with 40 non-food pictures. The second objective was to provide a ready-to-use database with normative data regarding responses and associations between demographic, anthropometric and eating-related characteristics, and picture ratings. PARTICIPANTS: A sample of 264 participants rated the total set of pictures. MEASURES: Attractiveness, arousal and palatability were assessed for each picture, as well as participant's current type of diet, BMI, hunger levels and eating behaviors (uncontrolled and emotional eating). RESULTS: Image characteristics (shape, colors, luminance) were comparable between food and matched non-food pictures. Positive correlations were found between hunger levels and attractiveness, arousal and palatability of food. Uncontrolled and emotional eating was positively correlated with high-calorie food palatability, and uncontrolled eating was positively correlated with high-calorie food attractiveness. Participants who did not report any specific diet rated high-calorie foods as more attractive and arousing, whereas vegan and vegetarian participants assessed low-calorie foods as more attractive and palatable. CONCLUSION: The Food-Cal controlled set of picture database can be considered as a useful tool for experimental research. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

Relationship between Tobacco Craving and Quality of Life among French Students: Results of a Cross-Sectional Study.

BACKGROUND: Understanding the factors leading to smoking cessation is of primary importance in reducing the death burden. Recently introduced in the DSM-5, craving is a potentially promising mechanism involved in relapse, but its articulation with quality of life and deprivation on tobacco student's consumers has never been investigated. OBJECTIVES: Our study explores the relationship between tobacco craving and sub-dimensions of quality of life when controlling effect of deprivation on a youth population with tobacco consumption. METHOD: Comparison between deprived and non-deprived students were conducted with online questionnaires on demographic data, level of dependency, perceived quality of life, deprivation and craving. Multivariate linear regression with backward procedure was conducted to assess the predictive validity of these variables on craving. Finally, Bayesian analysis was conducted to evaluate the model proposed by the regression. RESULTS: One hundred and seventy-four participants were included. Craving was significantly correlated with all the other variables and increases when the level of deprivation rises, while it decreases when physical health improves. These results are confirmed by Bayesian linear regression. Conclusions/Importance: Environmental and social factors are usually overlooked when it comes to understanding individuals, deeply rooted biological mechanisms such as craving. Working on physical health is of interest to diminished craving and improves the quality of life during smoking cessation and thereby to support success on the student population. Consequences for the triadic neurocognitive model of addiction are discussed.

Dynamic Exposure to Alcohol Advertising in a Sports Context Influences Implicit Attitudes.

BACKGROUND: Experimental studies investigating the impact of advertising with ecological stimuli on alcohol-related cognition are scarce. This research investigated the cognitive processes involved in learning implicit attitudes toward alcohol after incidental exposure to alcohol advertisements presented in a dynamic context. We hypothesized that incidental exposure to a specific alcohol brand would lead to heightened positive implicit attitudes toward alcohol due to a mere exposure effect. METHODS: In total, 108 participants were randomly exposed to dynamic sporting events excerpts with and without advertising for a specific brand of alcohol, after completing self-reported measures of alcohol-related expectancies, alcohol consumption, and attitudes toward sport. Participants then completed a lexical decision task and an affective priming task. RESULTS: We showed that participants were faster to detect brand name after being exposed to advertising during a sports game, and that implicit attitudes of participants toward the brand were more positive after they were exposed to advertising, even when alcohol usage patterns were controlled for. CONCLUSIONS: Incidental exposure to alcohol sponsorship in sport events impacts implicit attitudes toward the advertised brand and alcohol in general. The effect of incidental advertising on implicit attitudes is also likely to be due to a mere exposure effect. However, further studies should address this point specifically.

Preventing Alcohol Abuse Through Social Networking Sites: A First Assessment of a Two-Year Ecological Approach.

BACKGROUND: Prevention strategies to reduce alcohol use/consumption among young people are crucial to reducing alcohol-related deaths and preventing disease. This paper focuses on the effectiveness of a social networking site (SNS) alcohol prevention program targeted toward young people. OBJECTIVE: We hypothesized that the program would diminish the relation made by participants between alcohol and festive moments, and would result in a reduction of their declared consumption of alcohol at festive moments during the program. We also explored the interaction with the prevention program that was the most efficient. METHODS: The prevention program took the form of 3 lotteries over 2 years. The participants periodically received prevention messages, particularly on alcohol and festive moments (eg, videos on Facebook and short message service [SMS] text messages on their mobile phones). For the 3 periods, the participants had to answer questions exploring the level of their belief that alcohol consumption and festive moments are highly associated. A control group that did not participate in the prevention program was asked the same questions over the same number of days for the first 2 periods. During the second period, the participants were asked to answer questions about their alcohol consumption during parties. During the third period, we explored the interaction with the prevention program on the reduction of their belief that alcohol consumption and festive moments are associated. RESULTS: A total of 651 participants (age: mean 22.24, SD 4.10 years; women: n=430) during the first period, 301 participants (age: mean 21.27, SD 3.07 years; women n=199) during the second period, and 305 (age: mean 22.41, SD 4.65 years; women: n=190) during the third period correctly completed the survey. For the control group, 69 students completed the survey during the first period (age: mean 18.93, SD 1.14 years; women: n=59) and 50 during the second (age: mean 20.78, SD 1.94 years; women: n=45). We observed a significant reduction in the association of alcohol with festive moments in the participants over the 2 years (period 1: z=-4.80, P<.001; period 2: z=-2.11, P=.04; period 3: z=-2.30; P=.02), but not in the controls. We also observed a reduction in the number of glasses consumed during festive moments for the participants (z=-2.36, P=.02), but not for the controls during the second period. The third period showed that only the number of days since registration in the program had an impact on the reduction of the association of festive moments and alcohol consumption (t21=3.186, P=.005). CONCLUSIONS: The findings of this study suggest that the SNS prevention program is promising in preventing the association of alcohol with festive moments and, more generally, in impacting social norms.

Neuropsychological assessment fails to predict relapse among cigarette smokers: A prospective study of neurocognitive abilities.

OBJECTIVES: Understanding the factors that lead to relapse is a major challenge for the clinical support of smoking cessation. Neurocognitive abilities such as attention, executive functioning and working memory, are possible predictors of relapse and can be easily assessed in everyday clinical practice. In this prospective longitudinal study, we investigated the relationship between pre-smoking cessation neurocognitive performance and relapse at six months in a sample of patients being treated for their tobacco dependence. METHODS: 130 tobacco consumers were included in the study. They completed a comprehensive neuropsychological and clinical assessment before smoking cessation. The targeted abilities were intelligence, inhibition, shifting, working memory updating, verbal fluency and decision-making. RESULTS: The rate of tobacco relapse at 6 months was 58%. Logistic regressions were used to assess which variables best explained relapse. None of the neuropsychological tests was a significant predictor of relapse at either 1, 3 or 6 months, either alone, or controlling for other covariates acting as significant predictors of relapse. CONCLUSIONS: Common neuropsychological tests, even those specifically targeting executive functioning such as inhibition, are not useful predictors of the success of a smoking cessation program in a clinical setting. Other variables, such as motivation to quit smoking or the presence of comorbid depression or anxiety disorders, appear to be more useful predictors of relapse.

Cannabis Use in Physicians: A Systematic Review and Meta-Analysis.

Background: Cannabis use by physicians can be detrimental for them and their patients. We conducted a systematic review and meta-analysis on the prevalence of cannabis use by medical doctors (MDs)/students. Method: PubMed, Cochrane, Embase, PsycInfo and ScienceDirect were searched for studies reporting cannabis use in MDs/students. For each frequency of use (lifetime/past year/past month/daily), we stratified a random effect meta-analysis depending on specialties, education level, continents, and periods of time, which were further compared using meta-regressions. Results: We included 54 studies with a total of 42,936 MDs/students: 20,267 MDs, 20,063 medical students, and 1976 residents. Overall, 37% had used cannabis at least once over their lifetime, 14% over the past year, 8% over the past month and 1.1 per thousand (‱) had a daily use. Medical students had a greater cannabis use than MDs over their lifetime (38% vs. 35%, p < 0.001), the past year (24% vs. 5%, p < 0.001), and the past month (10% vs. 2%, p < 0.05), without significance for daily use (0.5% vs. 0.05%, NS). Insufficient data precluded comparisons among medical specialties. MDs/students from Asian countries seemed to have the lowest cannabis use: 16% over their lifetime, 10% in the past year, 1% in the past month, and 0.4% daily. Regarding periods of time, cannabis use seems to follow a U-shape, with a high use before 1990, followed by a decrease between 1990 and 2005, and a rebound after 2005. Younger and male MDs/students had the highest cannabis use. Conclusions: If more than a third of MDs tried cannabis at least once in their lifetime, this means its daily use is low but not uncommon (1.1‱). Medical students are the biggest cannabis users. Despite being common worldwide, cannabis use is predominant in the West, with a rebound since 2005 making salient those public health interventions during the early stage of medical studies.

Selflife: A Life Skills Development Tool to Prevent Sexual Violence among Healthcare Students.

BACKGROUND: in France, 14.5% of women and 3.9% of men aged 20-69 years have experienced sexual violence. Of these, 40% will go on to develop posttraumatic stress disorder. Sexual violence is therefore a major public health issue. In the present study, we tested a life skills development tool (Selflife) designed to prevent sexual violence in a population of healthcare students. METHODS: a total of 225 French healthcare students were randomly divided into a control group using case studies (n = 114) and a group using Selflife (n = 111) to discuss the topic of sexual violence. After the session, they completed self-report questionnaires collecting sociodemographic data and probing their feelings about their participation, their life skills, and their verdict on the intervention. RESULTS: compared with controls, participants in the Selflife group reported gaining more knowledge about sexual violence, a greater sense of improving their life skills, and greater satisfaction with the intervention. CONCLUSIONS: these results suggest that, in addition to providing information about sexual violence, Selflife helped students develop their life skills, thereby empowering them to act when confronted with sexual violence. Its impact on prevalence and on the psychological and psychiatric consequences remains to be assessed.

Crossed clinical features between eating disorders and types of bipolar disorder: Results from the FondaMental Advanced Centers of Expertise - Bipolar Disorder cohort.

BACKGROUND: Eating disorders (EDs) are liable to alter the disease course of bipolar disorder (BD). We explored the crossed clinical features between EDs and BD, particularly as a function of BD type (BD1 vs. BD2). METHODS: 2929 outpatients attending FondaMental Advanced Centers of Expertise were assessed for BD and lifetime EDs with a semi-structured interview, and their sociodemographic, dimensional and clinical data were collected according to a standardized procedure. For each ED type, bivariate analyses were used to investigate associations between these variables and the type of BD type followed by multinomial regressions with the variables associated with EDs and BDs after Bonferroni correction. RESULTS: Comorbid EDs were diagnosed in 478 (16.4 %) cases, and were more prevalent in patients with BD2 than in those with BD1 (20.6 % vs. 12.4 %, p < 0.001). Regression models showed no difference according to the subtype of bipolar disorder on the characteristics of patients with anorexia nervosa (AN), bulimia nervosa (BN) or binge eating disorder (BED). After multiple adjustments, the factors differentiating BD patients with versus without ED were primarily age, gender, body mass index, more affective lability and comorbidity with anxiety disorders. BD patients with BED also scored higher regarding childhood trauma. BD patients with AN also showed higher risk of past suicide attempts than those with BED. CONCLUSIONS: In a large sample of patients with BD, we found a high prevalence of lifetime EDs, especially for the BD2 type. EDs were associated with several severity indicators, but not with BD type-specific characteristics. This should prompt clinicians to carefully screen patients with BD for EDs, regardless of BD and ED types.

The effects of exposure to social media images of thin and average size women on body satisfaction among young women: Emotion regulation and self-efficacy as modulating factors.

Although appearance comparison has emerged as an important mechanism underlying the detrimental effects of exposure to idealized social media images on body image among young women, little is known regarding the role of the direction of these comparisons. In addition, to date, little attention has been paid to the role of self-regulation processes in these effects. A sample of 260 female students (Mage = 19.6) from a University in Paris completed an online survey where they were randomly assigned to view thin-ideal or average size social media images of women. Participants reported on state body satisfaction before and after exposure, as well as state appearance comparison and direction of appearance comparison, and trait emotion regulation difficulties and self-efficacy. Findings revealed no main effect of condition. However, among participants who engaged in upwards appearance comparison the thin-ideal condition was associated with greater decreases in body satisfaction. In addition, three-way interactions revealed that emotional regulation difficulties and self-efficacy both further moderated these effects. These findings suggest that self-regulation processes may be important to account for in the effects of exposure to social media images on body satisfaction among young women.

Evaluation of a Smartphone Application on the Reduction of Attentional Bias Toward Alcohol Among Students†.

CONTEXT: The recent development of "serious games" has produced encouraging results in maintaining adherence to health-related interventions. In alcohol research, several studies have shown that computerized training on attentional bias decreases alcohol consumption bias among students. However, these highly controlled experimental situations, do not allow for direct large-scale dissemination. Our objective is to evaluate an attentional bias remediation program using a gamified smartphone training procedure. METHODS: Fifty students from Clermont-Ferrand University were invited to participate in the study. After a cognitive assessment in the laboratory, the smartphone application was installed on each Student's smartphone. Participants were randomly assigned to either the alcohol attentional training group or the control group Each student had to complete the 2-min program at least once a day for 15 days. After 15 days, a new cognitive assessment of attention bias was conducted in the laboratory. Forty-seven students were included in the study. RESULTS: Our analyses did not show any effect of the cognitive remediation program on attentional bias reduction between the two group [F (1, 44) < 1, p = 0.87], attentional performance [F (1, 45) = 1.63, p = 0.20] or inhibitory abilities [F (1, 45) < 1, p = 0.73]. These results were confirmed by Bayesian analyses. DISCUSSION: Despite the absence of group effects, both the alcohol and control (non-alcohol) version of this program appeared to reduce attentional bias and increase inhibition capacities in the subset of participants who had attentional bias for alcohol at baseline This pilot study identifies areas for improvement in smartphone applications for future developments. Attentional bias remediation programs remain an interesting way to explore.

Effect of the COVID-19 pandemic on the psychotropic drug consumption.

Importance: Although the COVID-19 pandemic has had a negative impact on mental health, there is no comprehensive longitudinal study of the entire population of a country without selection bias. Objective: The objective of this study was to evaluate the prescription of psychotropic drugs during the COVID-19 pandemic, using data from the French national health data system (SNDS). Design settings and participants: Prescriptions for psychotropic drugs (antidepressants, anxiolytics, hypnotics, and antipsychotics) from 1 January 2015 to 30 September 2021 were collected from administrative data provided by the SNDS. This database includes more than 99% of the French population, i.e., 67 million people. The data were analyzed using an interrupted time series analysis (ITSA) model. Main outcomes and measures: Consumption of psychotropic drugs was aggregated in months and expressed in number of boxes per thousand inhabitants. Results: During the study period, more than 1.3 billion boxes of psychotropic medications were dispensed. Comparison of psychotropic drug dispensing before and after the pandemic showed a relative increase of 0.76 (95 CI 0.57 to 0.95, p<0.001) boxes per month per thousand inhabitants, all classes of psychotropic drugs combined. Three classes saw their consumption increase in an almost similar proportion, respectively, by 0.23 (0.15 to 0.32, p<0.001) boxes for antidepressants, 0.27 (0.20 to 0.34, p<0.001) boxes for anxiolytics and 0.23 (0.17 to 0.30, p<0.001) boxes for hypnotics. The change in antipsychotic consumption was very small, with an increase of 0.04 boxes (0.02 to 0.06, p = 0.001) per month per thousand population. Conclusion and relevance: The COVID-19 pandemic had led to an increase in the consumption of psychotropic drugs, confirming the significant impact of the pandemic on the mental health of the general population.

Self-Efficacy Mediates the Effect of Framing Eating Disorders Prevention Message on Intentions to Have a Sufficient Weight: A Pilot Study.

BACKGROUND: In the context of social marketing, the effectiveness of prevention messages is a major issue. The main objective of the present study was to assess the effect of prevention messages framing on self-efficacy reinforcement in order to improve intentions to reach or maintain sufficient weight in a non-clinical sample. It thus focuses on testing the mediating role of self-efficacy. METHODS: Two hundred and thirty-three university student women were randomly assigned to one of the two conditions (gain-framed versus loss-framed message). They were exposed to a short persuasive message and surveyed on self-efficacy and intention to maintain sufficient weight. RESULTS: Loss-framed messages elicited higher levels of self-efficacy than gain-framed messages, which led to higher intentions to reach or maintain sufficient weight. This study sheds light on the mediating role of self-efficacy. CONCLUSIONS: The results suggest ways to improve the persuasiveness of prevention campaigns, thereby opening up further research avenues.

Cognitive function in binge eating disorder and food addiction: A systematic review and three-level meta-analysis.

BACKGROUND: An extensive body of recent research has focused on the contribution of cognitive functioning to eating behaviors. In binge eating disorder (BED) and food addiction (FA), the extent of cognitive impairment is still unclear. This study aimed to characterize, among those with BED and FA, neurocognitive functions using performances based on neuropsychological tasks in the context of neutral stimuli in adults. METHOD: MEDLINE, Embase, PsycINFO, Cochrane Database of Systematic Reviews, CINAHL and gray literature (ProQuest and OpenGrey) were used to identify studies that reported neurocognitive assessments in BED or FA up to December 2019. A three-level meta-analysis was conducted. RESULTS: A significant overall effect was found for global cognitive impairments, suggesting that individuals with BED or FA have poorer performances when completing cognitive tasks. Analyses for specific cognitive domains revealed that individuals with BED showed poorer performances at tasks assessing cognitive flexibility, inhibitory control, attention and planning. Analyses regarding FA were inconclusive due to a lack of studies. Thus, the results were described qualitatively. CONCLUSION: Our meta-analysis highlighted the cognitive weaknesses that seem to come with BED and the necessity to integrate them in the assessment and treatment of this condition. It also stressed the lack of quality studies surrounding the cognitive features of FA.

Lockdown Impact on Stress, Coping Strategies, and Substance Use in Teenagers.

BACKGROUND: In response to the COVID-19 pandemic, the French government took many measures, the most notable of which was a national lockdown on 17 March 2020. Its effects have been widely studied, but to our knowledge, no study has sought to determine how adolescents have adapted to cope with this situation. The present study set out to explore teenagers' stress levels, coping strategies, and substance use during this period. METHODS: This paper is a cross-sectional study that rides on an existing prevention program interviewed 348 French middle school students (209 girls and 139 boys) in grade 8 (M age = 13.45; SDage = 0.54) using an online questionnaire between March 17 and May 11, 2020 (COVID-19 lockdown). The study examined the teenagers' perceived stress, coping strategies they had used, including recent use of tobacco, alcohol and cannabis, during COVID-19 lockdown. RESULTS: Teenagers reported lower perceived stress during lockdown than usually, with a significant decrease for girls. Those who perceived the least social support reported the highest levels of stress. The strategies of planning, behavioral disengagement, self-distraction, positive reframing, acceptance, and religion were used more than usual, while active coping and self-blame were used less. Acceptance was the most often used strategy and a source of decreased stress during lockdown. A significant decrease in recent tobacco, alcohol and cannabis use was also observed. CONCLUSION: Changes in the use of coping strategies, withdrawal from the stressful school environment, and greater exposure to parents than to peers caused adolescents to be less stressed and to decrease their substance use during the lockdown.
