Interference-based methods to mitigate gambling craving: a proof-of-principle pilot study

Craving is central in the prognosis of gambling disorder. The elaborated intrusion theory (EIT) provides a sound framework to account for craving in addictive disorders, and interference methods inspired from the EIT have substantiated their effectiveness in mitigating substance and food-related cravings. The principle of these methods is to recruit the cognitive resources underlying craving (e.g., visuospatial skills, mental imagery) for another competitive and cognitively demanding task, thus reducing the vividness and overwhelming nature of craving. Here we conducted two experiments employing a between-subjects design to test the efficacy of interference methods for reducing laboratory-induced craving. In these experiments, gamblers (n = 38 for both experiments) first followed a craving induction procedure. They then performed either a visuospatial interference task (making a mental and vivid image of a bunch of keys [experiment 1] or playing the video game Tetris [experiment 2]; experimental conditions) or another task supposed not to recruit visuospatial skills and mental imagery (exploding bubble pack [experiment 1] or counting backwards [experiment 2]; control conditions). Results show that all methods successively mitigated induced craving. Although previous research evidenced the superiority of visuospatial tasks to reduce substance-related craving, our findings question their superiority in the context of gambling craving

Measurement invariance of the Marijuana Motives Measure among men and women using Stop Cannabis App

Motives to use cannabis play a central role in the development and maintenance of problematic cannabis use and previous studies stressed sex-related differences on motives to use cannabis. However, motives cannot be validly compared in men and women without first establishing the measurement invariance across sex. Therefore, the aim of the study is to (1) examine for the first time the measurement and structural invariance of the Marijuana Motives Measure (MMM) across sex, and (2) to investigate the motives for cannabis use that best explain problematic use. 2951 (41.7% women) users of the "Stop cannabis" smartphone app of which 99.8% reported having used cannabis in the last three months completed an online MMM and ASSIST to assess the severity of their problematic cannabis use. Multigroup confirmatory factor analyses supported measurement invariance across sex, whereas structural invariance was not confirmed. Indeed, group comparisons indicated that women reported greater coping motives then men whereas men showed greater social motives than women. A multiple linear regression analysis showed that only coping and conformity motives were significantly associated with greater problematic cannabis use, whereas neither sex nor the sex by motives interactions were significantly related to problematic cannabis use. The MMM appears to function comparably across men and women. Therefore, sex-related comparisons on the questionnaire can be considered valid. Coping and conformity motives may play a central role part in the development of marijuana use problems which may hold implications for intervention development and public policy

Determinants of the development of post-traumatic stress disorder, in the general population

Purpose: To assess (1) the lifetime prevalence of exposure both to trauma and post-traumatic stress disorder (PTSD); (2) the risk of PTSD by type of trauma; and (3) the determinants of the development of PTSD in the community. Methods: The Diagnostic Interview for Genetic Studies was administered to a random sample of an urban area (N=3,691). Results: (1) The lifetime prevalence estimates of exposure to trauma and PTSD were 21.0 and 5.0%; respectively, with a twice as high prevalence of PTSD in women compared to men despite a similar likelihood of exposure in the two sexes; (2) Sexual abuse was the trauma involving the highest risk of PTSD; (3) The risk of PTSD was most strongly associated with sexual abuse followed by preexisting bipolar disorder, alcohol dependence, antisocial personality, childhood separation anxiety disorder, being victim of crime, witnessing violence, Neuroticism and Problem-focused coping strategies. After adjustment for these characteristics, female sex was no longer found to be significantly associated with the risk of PTSD. Conclusions: The risk for the development of PTSD after exposure to traumatic events is associated with several factors including the type of exposure, preexisting psychopathology, personality features and coping strategies which independently contribute to the vulnerability to PTSD

Factors associated with disordered eating behaviors and attitudes in older women

Purpose : The present study explored the potential factors associated with disordered eating behaviors and attitudes in older women. Methods : Women aged 60–75 years were recruited in the community (n = 203) and completed questionnaires. The Eating Disorder Examination-Questionnaire (EDE-Q) was used to evaluate disordered eating behaviors and attitudes. The independent variables were BMI, age, importance of appearance, importance of body competence, cognitive reappraisal, and fear of age-related appearance changes. Spearman correlation analyses and zero-inflated negative binomial regression models were used to analyze the data. Results : BMI was positively associated with EDE-Q restraint, EDE-Q eating concern, and EDE-Q frequency of objective binge-eating episodes. Importance of appearance was positively related to EDE-Q restraint, and fear of age-related appearance changes to EDE-Q eating concern and objective binge-eating episodes. Cognitive reappraisal was negatively associated with EDE-Q eating concern and excessive exercise in bivariate associations, but the relationships disappeared in the multivariate analyses. Conclusions : BMI, importance of appearance, and fear of age-related appearance changes turned out to be positively associated with eating disordered behaviors and attitudes, similarly to what can be observed in middle-aged samples. However, the role of cognitive reappraisal was unclear and should be investigated further

Body image concerns and intuitive eating in older women

Intuitive eating has been described as representing a positive relationship with food that can support health. However, to date, most of the extant research on intuitive eating has been conducted among young women, limiting our understanding of how intuitive eating can contribute to supporting health in aging women. This study aimed to bridge this gap by exploring body image and eating correlates of intuitive eating in older women. The hypotheses were that among older women, intuitive eating would be significantly associated with lower disordered eating, weight and shape concerns, and fewer depressive symptoms, and that an indirect relationship between BMI and intuitive eating via weight and shape concerns would exist. Community women aged 60–75 (N = 200) completed questionnaires assessing intuitive eating, disordered eating, body concern, depressive symptoms and body mass index (BMI). Higher intuitive eating global scores were associated with lower restraint, lower eating concern, lower body concern, fewer depressive symptoms, and lower BMI. An indirect relationship between BMI and intuitive eating via weight and shape concern emerged, suggesting that being preoccupied by one's appearance hinder the ability to practice intuitive eating. These results suggest that intuitive eating is associated with positive outcomes among older women and might be a useful target for interventions designed to increase healthy aging

Body image and disordered eating in older women ::a tripartite sociocultural model

Evidence suggests that body image concerns and disordered eating exist in women even at older ages. Few studies have examined the factors that are related with body image and eating concerns in this age group. In particular, the roles of sociocultural influences and thin-ideal internalization remain unclear. In the present study, we tested a modified tripartite sociocultural model of body image and disordered eating behaviors in a sample of 222 women aged 60 to 75 years, using structural equation modeling. After adjustment, a model similar to that observed in young women was a good fit to the data. Perceived pressure from the media revealed a direct relationship with body image concerns, as well as an indirect relationship mediated by thin-ideal internalization. Peer pressure was directly associated with body image concerns, and thin-ideal internalization was associated with dieting. In older women, pressure to conform to appearance ideals, in particular from the media, may impact the internalization of appearance ideals and body image concerns that might, in turn, increase disordered eating. The usefulness of sociocultural models for framing body image and eating concerns in older women implies that similar prevention interventions to those used in younger women could be adapted to fill a gap in available resources for this group
