Validation of the French version of the yale food addiction scale: an examination of its factor structure, reliability, and construct validity in a nonclinical sample.

Objective: The concept of food addiction has recently been proposed by applying the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, criteria for substance dependence to eating behaviour. Food addiction has received increased attention given that it may play a role in binge eating, eating disorders, and the recent increase in obesity prevalence. Currently, there is no psychometrically sound tool for assessing food addiction in French. Our study aimed to test the psychometric properties of a French version of the Yale Food Addiction Scale (YFAS) by establishing its factor structure and construct validity in a nonclinical population. Method: A total of 553 participants were assessed for food addiction (French version of the YFAS) and binge eating behaviour (Bulimic Investigatory Test Edinburgh and Binge Eating Scale). We tested the scales factor structure (factor analysis for dichotomous data based on tetrachoric correlation coefficients), internal consistency, and construct validity with measures of binge eating. Results: Our results supported a 1-factor structure, which accounted for 54.1% of the variance. This tool had adequate reliability and high construct validity with measures of binge eating in this population, both in its diagnosis and symptom count version. A 2-factor structure explained an additional 9.1% of the variance, and could differentiate between patients with high, compared with low, levels of insight regarding addiction symptoms. Conclusions: In our study, we validated a psychometrically sound French version of the YFAS, both in its symptom count and diagnostic version. Future studies should validate this tool in clinical samples.

Major depressive disorder, personality disorders and coping strategies are independent risk factors for lower quality of life in non-metastatic breast cancer patients.

Our aim was to identify risk factors for lower quality of life (QOL) in non‐metastatic breast cancer patients.

High Preoperative Depression, Phobic Anxiety, and Binge Eating Scores and Low Medium-Term Weight Loss in Sleeve Gastrectomy Obese Patients: A Preliminary Cohort Study

OBJECTIVE Although depression, anxiety, and binge eating are prevalent in candidates for bariatric surgery, their impact on weight loss is unknown following sleeve gastrectomy. This study assesses the associations between weight loss and preoperative depression, anxiety, and binge eating scores in patients undergoing sleeve gastrectomy for morbid obesity. METHOD This cohort study included 34 patients who underwent sleeve gastrectomy for morbid obesity between May 2006 and February 2010 in a French tertiary referral center. We assessed preoperative depression (using the Beck depression inventory and the SCL-90-R depression subscale), anxiety (using the Hamilton anxiety rating scale and the SCL-90-R anxiety subscales), and binge eating (using the bulimic investigatory test, Edinburgh). The primary outcome was the percentage of excess weight loss at 12 months (PEWL). RESULTS The preoperative mean body mass index (BMI) was 55.3 kg/m2 ± 10.2 kg/m2 and 41.7 kg/m2 ± 8.7 kg/m2 at the 12-month follow-up visit. The mean PEWL was 46.8% ± 15.8%. After adjusting for the preoperative BMI, the PEWL was negatively associated with preoperative scores for depression (β= -0.357; P < 0.05), phobic anxiety (β = -0.340; P < 0.05), interpersonal sensitivity (β = -0.328; P < 0.05), and binge eating (β = -0.315; P = 0.05). Other forms of anxiety were not correlated with the PEWL. CONCLUSIONS Higher preoperative depression, phobic anxiety, interpersonal sensitivity, and binge eating scores are associated with low postoperative weight loss in patients undergoing sleeve gastrectomy. Future studies should assess the preoperative prevalence of syndromal or subsyndromal atypical depression and its relationship to postoperative weight loss in bariatric surgery candidates.

Validation of the French Version of the DSM-5 Yale Food Addiction Scale in a Nonclinical Sample

Objective: The Yale Food Addiction Scale (YFAS) is the only questionnaire that assesses food addiction (FA) based on substance dependence criteria in the Diagnostic and Statistical Manual of Mental Disorders (DSM), Fourth Edition, Text Revision. Following recent updating of addiction criteria, a new DSM-5 version (YFAS 2.0) has been developed. Our study tested the psychometric properties of the French YFAS 2.0 in a nonclinical population. Method: We assessed 330 nonclinical participants for FA (French YFAS 2.0), eating behaviour, and eating disorder (Binge Eating Scale, Emotional Overeating Questionnaire, Three-Factor Eating Questionnaire-R18, Questionnaire on Eating and Weight Patterns-Revised, Eating Disorder Diagnostic Scale). We tested the scale’s factor structure (confirmatory factor analysis based on 11 diagnostic criteria), internal consistency, and construct and incremental validity. Results: Prevalence of FA was 8.2%. Our results supported a 1-factor structure similar to the US version. In both its diagnostic and symptom count versions, the YFAS 2.0 had good internal consistency (Kuder-Richardson alpha was 0.83) and was associated with body mass index (BMI), binge eating, uncontrolled and emotional eating, binge eating disorder, and cognitive restraint. FA predicted BMI above and beyond binge eating frequency. Females had a higher prevalence of FA than males but not more FA symptoms. Conclusions: We validated a psychometrically sound French version of the YFAS 2.0 in a nonclinical population, in both its symptom count and diagnostic versions. Future studies should investigate psychometric properties of this questionnaire in clinical populations potentially at risk for FA (that is, patients with obesity, diabetes, hypertension, or other metabolic syndrome risk factors).

Sensation Seeking and Cocaine Dependence in Adults With Reported Childhood ADHD

Objective: To compare measures of sensation seeking in a clinical group of cocaine-dependent (CD) patients with and without a history of probable childhood ADHD and in non-cocaine-dependent (NCD) healthy volunteers. Method: Patients (n = 75; 42 with and 33 without probable childhood ADHD) and comparisons (n = 84) were assessed with the Diagnostic Interview for Genetic Studies, the Wender Utah Rating Scale for childhood ADHD, and the Zuckerman Seeking Sensation Scale. Results: We found significantly higher prevalence rates of probable childhood ADHD in CD versus NCD (p < .001). The mean total scores of sensation seeking were significantly higher in CD versus NCD participants (p < .001) as well as in CD patients with versus those without a probable history of childhood ADHD (p < .001). Conclusion: Our study sets the basis for longitudinal investigation assessing whether the persistence of high level of sensation seeking in adults with childhood ADHD contributes to the transition to cocaine dependence.

Depression is associated with some patient-perceived cosmetic changes, but not with radiotherapy-induced late toxicity, in long-term breast cancer survivors.

Although depression is prevalent in long‐term breast cancer survivors (LTBCS; ≥5 years since diagnosis), it is underdiagnosed and undertreated. A better understanding of factors associated with depression could improve depression screening, treatment, and prevention in this population. Our study aimed to assess the link between patient and doctor ratings of breast cosmetic outcomes, late radiotherapy toxicity, and depression in LTBCS.

Do Transactive Memory and Participative Teamwork Improve Nurses’ Quality of Work Life?

Improvement in nurses’ quality of work life (QWL) has become a major issue in health care organizations. We hypothesized that the level of transactive memory (defined as the way groups collectively encode, store, and retrieve knowledge) and participative teamwork (an organizational model of care based on vocational training, a specific service’s care project, and regular interdisciplinary staffing) positively affect nurses’ QWL. This cross-sectional study enrolled 84 ward-based psychiatric nurses. We assessed transactive memory, participative teamwork, perceived organizational justice, perceived organizational support, and QWL using psychometrically reliable and valid scales. Participative teamwork and transactive memory were positively associated with nurses’ QWL. Perceived organizational support and organizational justice fully mediated the relationship between participative teamwork and QWL, but not between transactive memory and QWL. Improved transactive memory could directly improve nurses’ QWL. Improved participative teamwork could improve nurses’ QWL through better perceived organizational support and perceived organizational justice.

Impact des complications tardives de la radiothérapie, de la dépression et de l’anxiété sur la qualité de vie à long terme dans le cancer du sein

INTRODUCTION This study aimed to assess the impact of late treatment toxicity (especially radiotherapy toxicity), chemoradiotherapy treatment type (concurrent or sequential), depression and anxiety on overall, physical and emotional quality of life (QoL) in long-term breast cancer survivors. Method. We assessed 117 patients (mean follow-up since the end of treatment = 8.1 years) for late radiotherapy toxicity (LENT-SOMA scale), patient and doctor ratings of breast cosmetic outcomes, QoL (EORTC QLQ-C30), depression and anxiety (Hospital and Anxiety Depression scale). RESULTS In univariate analyses, factors associated with significantly decreased QoL were: use of sequential treatment and decreased overall QoL (P = 0.002) and emotional QoL (P = 0.02) ; few radiotherapy late toxicity symptoms (pain and decreased physical QoL, P = 0.01 ; fibrosis and decreased emotional QoL, P = 0.04) ; probable depression or probable anxiety and decreased overall, physical and emotional QoL (P ≤ 0.005). In multivariate analyses, probable depression and probable anxiety were the most stronger predictors for decreased QoL in the overall, physical and emotional domains (P ≤ 0.02). CONCLUSION Improving screening for and treatment of depression and anxiety might improve QoL in long-term breast cancer survivors.

Why do liver transplant patients so often become obese? The addiction transfer hypothesis

In patients who receive transplantation for alcohol liver disease, obesity and metabolic syndrome are highly prevalent after transplantation and both contribute to a significant proportion of cardiovascular complications, late morbidity and mortality in this population. Although immunosuppressive medications have been hypothesised to explain some of these post-liver transplantation (LT) metabolic complications, they cannot be considered the sole cause of obesity and metabolic syndrome, and the high prevalence of these illnesses remains unexplained. Given the significant overlap between the neurobiological, psychiatric and psychological factors that underlie alcohol addiction and reward-related behavioural dyscontrol disorders such as food addiction (FA), we hypothesised that the high prevalence of obesity and metabolic syndrome reported in patients who receive transplantation for alcohol liver disease could be explained at least partially by a switch in some individuals from a previous alcohol addiction to post-transplantation FA (i.e., addiction transfer = addiction switch). In our integrative model, we also speculate that an increased prevalence of FA or alcohol addiction may occur in patients with both specific psychobiological profiles and shared risk factors. We further hypothesise that in the subpopulation of patients who develop either alcohol addiction or FA after LT, those with high insight with regard to the consequences of alcohol use could be at higher risk for FA, whereas those with low insight could be at higher risk for alcohol addiction. We discuss here evidence for and against this hypothesis and discuss which patients could be more vulnerable to these two addictions after LT. Because it will not be either possible or ethical to test some of our hypotheses in humans, future studies should test these hypotheses using a translational strategy, using both clinical and preclinical approaches. If our hypotheses could account for the significant increase in obesity and metabolic syndrome after LT, this would lead to new avenues for research and preventive as well as therapeutic interventions for alcohol-related LT patients. All patients with previous or current alcohol addiction should be systematically screened for FA and followed up for subsequent risk of obesity and metabolic syndrome. Such strategies might be effective in improving survival, outcomes and quality of life after LT and also in the overall population of patients with alcohol addiction. By determining common risk factors for both alcohol addiction and FA using a translational approach, our model could help to find novel psychopharmacological and psychological strategies that might be effective in both FA and alcohol addiction.

Abrupt onset of disturbed vigilance, bilateral third nerve palsy and masturbating behaviour: a rare presentation of stroke.

The clinical presentation of stroke usually includes sensory–motor impairment, cranial nerve palsies, or cognitive dysfunction. Disorders in behaviour are less frequently seen. The case of a patient with a very disturbing presentation, which included a disturbance in vigilance, bilateral third nerve palsy and masturbating behaviour, is presented. The topography of the lesions and its implications on the deficits observed are discussed.
