Abstract
Trait impulsivity represents a tendency to take action without forethought or consideration of consequences. This trait is multifaceted and can be decomposed into attentional, motor and non-planning subtypes of impulsivity. The purpose of the current study was to investigate how subtypes of trait impulsivity responded to different degrees of threat within room-scale virtual reality (VR) with respect to behaviour and level of physiological activation. Thirty-four participants were required to negotiate a virtual environment (VE) where they walked at height with the continuous threat of a virtual 'fall.' Behavioural measures related to the speed of movement, interaction frequency and risk were collected. Participants also wore ambulatory sensors to collect data from electrocardiogram (ECG) and electrodermal activity (EDA). Our results indicated that participants who scored highly on non-planning impulsivity exhibited riskier behaviour and higher skin conductance level (SCL). Participants with higher motor impulsivity interacted with more objects in the VE when threat was high, they also exhibited contradictory indicators of physiological activation. Attentional impulsivity was associated with a greater number of falls across the VE. The results demonstrate that subtypes of trait impulsivity respond to threats via different patterns of behaviour and levels of physiological activation, reinforcing the multifaceted nature of the trait.

Abstract
Gambling opportunities have greatly expanded in recent years leading to an alternative form of leisure but also raising social concerns. Participation in such activities may be conditioned by individual characteristics affecting the willingness of individuals to gamble, including gender, but also by time effects linked to the availability and exposure of gambling. Using data from Spain, estimates from a time-varying split population duration model show significant gender differences in the propensity to start gambling (men's episodes as non-gamblers were observed to be shorter than women's). Additionally, expansion of gambling opportunities over time is found to be correlated with an increase in the propensity to start gambling. Both men and women are clearly more likely to start gambling at earlier ages than before. These results are expected to improve knowledge of gender differences in terms of consumer decision making about gambling and to be helpful in designing public policies for gambling.

Gender difference in network relationship between inter-temporal decisions and prefrontal activation levels in internet gaming disorder. PSYCHORADIOLOGY 2023; 3:kkad015.

Abstract
Background Impulsivity and decision-making are key factors in addiction. However, little is known about how gender and time sensitivity affect impulsivity in internet gaming disorder (IGD). Objective To investigate the gender difference of impulsive decision-making and relevant brain responses in IGD. Methods We conducted a functional magnetic resonance imaging (fMRI) study with 123 participants, including 59 IGD individuals (26 females) and 64 matched recreational game users (RGUs, 23 females). Participants performed a delay-discounting task during fMRI scanning. We examined gender-by-group effects on behavioral and neural measures to explore the preference for immediate over delayed rewards and the associated brain activity. We also investigated the network correlations between addiction severity and behavioral and neural measures, and analyzed the mediating role of brain activity in the link between delay discounting parameters and IGD severity. Results We found significant gender-by-group interactions. The imaging results revealed gender-by-group interactions in the dorsolateral prefrontal cortex, medial frontal gyrus, and inferior frontal gyrus (IFG). Post hoc analysis indicated that, for females, RGUs showed higher activity than IGD individuals in these brain regions, while for males IGD individuals exhibited higher activity than RGUs. The activation in the left IFG mediated the relation between Internet Addiction Test score and discount rate in females. In males, the activation in the right dlPFC mediated the relation between IAT score and time sensitivity. Discussion Our findings imply that male IGD participants demonstrate impaired intertemporal decisions associated with neural dysfunction. Influencing factors for impulsive decision-making in IGD diverge between males (time sensitivity) and females (discount rate). These findings augment our comprehension of the neural underpinnings of gender differences in IGD and bear significant implications for devising effective intervention strategies for treating people with IGD.

Abstract
Sensorimotor dysfunction has been previously reported in persons with cannabis dependence. Such individuals can exhibit increased levels of neurological soft signs (NSS), particularly involving motor coordination, sensorimotor integration and complex motor task performance. Abnormal NSS levels can also be detected in non-dependent individuals with heavy cannabis use (HCU), yet very little is known about the functional correlates underlying such deficits. Here, we used resting-state functional magnetic resonance imaging (MRI) to investigate associations between NSS and intrinsic neural activity (INA) in HCU (n = 21) and controls (n = 26). Compared with controls, individuals with HCU showed significantly higher NSS across all investigated subdomains. Three of these subdomains, that is, motor coordination, sensorimotor integration and complex motor task behaviour, were associated with specific use-dependent variables, particularly age of onset of cannabis use and current cannabis use. Between-group comparisons of INA revealed lower regional homogeneity (ReHo) in left precentral gyrus, left inferior occipital gyrus, right triangular pat of the inferior frontal gyrus and right precentral gyrus in HCU compared with controls. In addition, HCU showed also higher ReHo in right cerebellum and left postcentral gyrus compared with controls. Complex motor task behaviour in HCU was significantly related to INA in postcentral, inferior frontal and occipital cortices. Our findings indicate abnormal ReHo in HCU in regions associated with sensorimotor, executive control and visuomotor-integration processes. Importantly, we show associations between ReHo, cannabis-use behaviour and execution of complex motor tasks. Given convergent findings in manifest psychotic disorders, this study suggests an HCU endophenotype that may present with a cumulative risk for psychosis.

Abstract
The aim of the study was to converge a structural equation model to unfold the compositive relationships between trait impulsivity, health cognitions, metacognitions about health, fear of COVID-19 and cyberchondria, after controlling for gender, age, marital status, having a chronic illness and chronic illness among first-degree relatives. Six hundred fifty-one participants (423 females, 65%; 228 males, 35%) participated in the study. The Short UPPS-P Impulsive Behavior Scale (S-UPPS-P), Health Cognitions Questionnaire (HCQ), The Meta-Cognitions about Health Questionnaire (MCQ-HA), Cyberchondria Severity Scale -Short Form (CSS-12), and Fear of COVID-19 Scale (FCV-19 S) were completed by volunteered participants. The structural model showed that the S-UPPS-P directly and indirectly contributed to the HCQ, MCQ-HA, CSS-12, and FCV-19 S. The multi-group structural analysis by gender showed that the structural model had a partial measurement and factorial invariance. We concluded that the significant associations between impulsivity, fear of COVID-19 and cyberchondria were indirectly contributed by health-related cognitions and metacognitions.

Abstract
This study aims to explore the associations between personality traits and depressive symptoms among Chinese adults and analyse the gender and age differences in the associations. A national representative sample of 28,628 adults aged 18 and above were selected from the 2018 China Family Panel Studies (CFPS) data. The short version of the Big Five Inventory (CBF-PI-15) and the Center for Epidemiologic Studies Depression (CES-D 8) were used to measure personality traits and depressive symptoms respectively. Binary logistic regression models were employed to analyse the associations between personality traits and depressive symptoms in the whole participants, different age groups and genders respectively. After adjustment, higher levels of conscientiousness, extraversion and agreeableness were related to lower level of depressive symptoms, while higher levels of openness and neuroticism were related to higher level of depressive symptoms (p < 0.05). A significant interaction between gender and conscientiousness on depressive symptoms was found (interaction p = 0.005), and the association between conscientiousness and depressive symptoms was stronger in males than females (p < 0.001). Significant interactions between age and conscientiousness (interaction p = 0.007), agreeableness (interaction p = 0.001) on depressive symptoms were found respectively. Moreover, the associations of conscientiousness and agreeableness with depressive symptoms were strongest among old group, followed by middle-aged group, and then young group (p < 0.05). In conclusion, conscientiousness, extraversion and agreeableness had negative associations with depressive symptoms, while openness and neuroticism had positive associations with depressive symptoms. The negative association between conscientiousness and depressive symptoms was stronger among males than females, and the negative associations of conscientiousness and agreeableness with depressive symptoms were strongest among old group, followed by middle-aged group, and then young group.

Abstract
AbstractBased on a sample of 372 adult employees who reported being LGB+, this cross-sectional study investigated whether and how personality is related to the disclosure of a non-heterosexual orientation at the workplace, which has not been systematically examined so far. Disclosure at work, the five-factor personality traits, self-esteem, impulsiveness, and locus of control were assessed based on prior findings and conceptual aspects alongside with potential covariates. The results suggest that age, the presence of an intimate relationship, and work hours per week incrementally predicted disclosure behavior at work, which is in line with previous studies. These factors significantly increased the likelihood of disclosing a non-heterosexual orientation at work. Regarding personality, bivariate correlation analyses showed that neuroticism, extraversion, conscientiousness, and internal locus of control are related to disclosure behavior at work. This would replicate previous findings on general disclosing behavior. However, when controlling for the shared variance with all relevant personality factors and covariates, only conscientiousness showed incremental validity in explaining disclosure behavior at work. Given that integrity and honesty, as well as authenticity, are key characteristics of conscientious individuals, it may be likely that conscientious LGB + employees tend to disclose their non-heterosexual orientation at work in order to be honest and authentic.

Abstract
Young adulthood is the period from the late teens through the twenties and is associated with life transitions that could contribute to the development of obesity. Targeting this group will be critical to reversing the obesity epidemic. The aim of the study was to investigate the eating behaviors and lifestyle of healthcare students in Poland. We enrolled 227 students in the study. Convenience sampling was employed. Diet (Food Frequency Questionnaire), physical activity (International Physical Activity Questionnaire), depressive symptoms (Beck Depression Inventory), impulsivity (Barratt Impulsivity Scale), and eating behaviors (Three-Factor Eating Questionnaire) were assessed. One in three students exhibited depressive symptoms, one in four showed low levels of physical activity. More than 40% of the students did not consume vegetables at least once a day, and more than half did not consume fruit. Only approximately 50% of the students ate fish several times a month. There was an association between high scores of specific eating behaviors and body weight, adherence to the Mediterranean diet, and consumption of specific product groups (sweets, alcohol). The results of our study are expected to contribute to a better understanding of dietary habits and overweight/obesity in university students, and support the development of programs to promote healthy lifestyles in that population.

Abstract
Background: The dopamine receptor D4 [DRD4] has been reported to be associated with substance use. Yet, the roles that health conditions and behaviors may play in such association are understudied.Objective: This longitudinal study investigated the potential mediation effects of chronic pain and delinquency in adolescence on the association between the DRD4 2-repeat allele and substance use in adulthood. Sex, witnessing violence, and experiencing violence were also examined as potential moderators for the mediation pathways.Methods: We used the restricted and candidate gene data from the National Longitudinal Study of Adolescent to Adult Health (Waves I-IV) to conduct secondary analysis (N = 8,671; 47% male). A two-step approach was adopted to examine the mediation effects regarding four substance use outcomes in adulthood: number of lifetime alcohol use disorder symptoms, lifetime regular smoker status, past-month smoking, and lifetime "pain killer" misuse. The moderation effects were investigated using stratification and permutation.Results: The DRD4 2-repeat allele was associated with all adulthood substance use outcomes through adolescent chronic pain and delinquency (AORs/IRR range 1.08-3.78; all ps<0.01). The association between delinquency and smoking was higher among females. The association between delinquency and substance use was lower among the participants who witnessed violence in adolescence.Conclusions: This study identified modifiable mediators underlying the association between the DRD4 2-repeat allele and substance use behaviors, concluding that chronic pain and delinquency partially explain the effect of the DRD4 gene polymorphism on adult substance use.

Alcohol Use and Gambling Associated with Impulsivity among a Swedish University Sample. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19042436.

Abstract
Excessive alcohol use and gambling can have negative consequences. Across countries, the risk of excessive alcohol use is more common in university populations than in the general population. However, few studies have investigated the prevalence of both alcohol use and gambling in this group. This study explores these behaviours in a Swedish university setting. In addition, this study investigates how impulsivity affects alcohol use and gambling. In total, 794 Swedish students answered an online survey. Data were analysed using descriptive statistics to determine prevalence, and multinomial logistic regression was used to determine the contribution of impulsivity, age, and sex to alcohol use and gambling. Compared to the Swedish national prevalence, the prevalence was higher for excessive alcohol use, but the prevalence of gambling was at the same level or lower. High levels of impulsivity and male sex increased the risk of excessive alcohol use, while older age lowered the risk of excessive alcohol use and gambling. The results indicate that primarily young men could benefit from primary prevention in a university setting. Also, screening for impulsivity in men might be one way to identify risk groups in a university population.

Abstract
Sensorimotor dysfunction has been previously reported in persons with cannabis dependence. Such individuals can exhibit increased levels of neurological soft signs (NSS), particularly involving motor coordination and sensorimotor integration. Whether such abnormalities may also apply to non-dependent individuals with heavy cannabis use (HCU) is unknown, as much as the neural correlates underlying such deficits. In this study, we investigated associations between NSS and gray matter volume (GMV) in males with HCU and male controls. Twenty-four persons with HCU and 17 controls were examined using standardized assessment of NSS and structural magnetic resonance imaging (MRI) at 3 T. GMV was calculated using voxel-based morphometry algorithms provided by the Computational Anatomy Toolbox (CAT12). Individuals with HCU showed higher NSS total scores compared to controls. In particular, significant NSS-subdomain effects were found for "motor coordination" (MoCo), "complex motor tasks" (CoMT), and "hard signs" (HS) expression in HCU (p < 0.05, Bonferroni-corrected). Compared to controls, persons with HCU showed significant NSS/GMV interactions in putamen and inferior frontal cortex (MoCo), right cerebellum (CoMT) and middle and superior frontal cortices, and bilateral precentral cortex and thalamus (HS). In between-group analyses, individuals with HCU showed lower GMV in the right anterior orbital and precentral gyrus, as well as higher GMV in the right superior frontal gyrus and left supplementary motor cortex compared to controls. The data support the notion of abnormal sensorimotor performance associated with HCU. The data also provide a neuromechanistic understanding of such deficits, particularly with respect to aberrant cortical-thalamic-cerebellar-cortical circuit.

Abstract
BACKGROUND Impulsivity has been identified as playing a role in cocaine use. The purpose of this study was to explore self-report measures of impulsivity in large groups of male and female cocaine users and matched controls and to determine if differences in impulsivity measures within a group of cocaine users related to self-reported money spent on cocaine and route of cocaine use. METHODS Eight self-report impulsivity measures yielding 34 subscales were obtained in 230 cocaine users (180 M, 50 F) and a matched group of 119 healthy controls (89 M, 30 F). Correlational analysis of the questionnaires revealed 2 factors: Impulsive Action (Factor 1) consisting of many traditional impulsivity measures and Thrill-seeking (Factor 2) consisting of delay discounting, sensation and thrill seeking. RESULTS Sex influenced within group comparisons. Impulsive Action scores did not vary as a function of sex within either group. But, male controls and male cocaine users had greater Thrill-seeking scores than females within the same group. Sex also influenced between group comparisons. Male cocaine users had greater Impulsive Action scores while female cocaine users had greater Thrill-seeking scores than their sex-matched controls. Among cocaine users, individuals who preferred insufflating ("snorting") cocaine had greater Thrill-seeking scores and lower Impulsive Action scores than individuals who preferred smoking cocaine. Individuals who insufflate cocaine also spent less money on cocaine. CONCLUSIONS Greater Impulsive Action scores in males and Thrill-seeking scores in females were associated with cocaine use relative to controls.

Abstract
Objective: Increased impulsiveness is a risk factor for health-endangering behavior patterns. Little is known about whether increased impulsiveness is associated with Internet Use Disorder (IUD) and whether individuals with various main activities on the internet differ in their levels of impulsiveness. Methods: In total, we screened 8,230 vocational students for problematic internet use with the Compulsive Internet Use Scale (CIUS). Participants scoring at least 21 points in the CIUS took part in an in-depth diagnostic interview. IUD was assessed according to the criteria of Internet Gaming Disorder (IGD) as suggested in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Impulsiveness was assessed with the Barratt Impulsiveness Scale (BIS-15). We analyzed the data using binary logistic regression models and nonparametric tests. Results: Participants with IUD (n = 144) showed increased impulsiveness (p = .005) compared to those without IUD (n = 774). Participants with different main activities on the internet did not differ in their levels of impulsiveness. Conclusions: Results indicate that impulsiveness is associated with IUD, independent of the main internet activity. This highlights the necessity to consider patients' impulsiveness in prevention and therapeutic approaches. Because of the cross-sectional study design, further research with longitudinal study designs is needed.

Abstract
OBJECTIVE To estimate the associations between a positive eating disorder screen and any lifetime eating disorder diagnosis and illicit drug use among a large, diverse sample of college students. METHOD We analyzed data from the national (United States), cross-sectional 2018-2019 Healthy Minds Study (HMS; n = 42,618; response rate: 16%). HMS collects information on the physical, mental, and social health of college students. Multiple logistic regression analyses were used to estimate the association between a positive eating disorder screen (measured using the SCOFF) and any self-reported lifetime eating disorder diagnosis and self-reported illicit drug use in the past 30 days (any illicit drug use and use of marijuana, cocaine, heroin, methamphetamines, stimulants, ecstasy, opioids, benzodiazepines), while adjusting for potential confounders. RESULTS Among the sample, 54.34% (n = 28,608) were female and the mean age of participants was 23.30 (SE ± 0.05) years. Logistic regression analyses revealed unique associations between a positive eating disorder screen and any lifetime eating disorder diagnosis and illicit drug use among the sample of college student participants. A positive eating disorder screen was most strongly associated with methamphetamine use (adjusted odds ratio [AOR] 3.93, 95% confidence interval [CI] 1.43-10.78), and any lifetime eating disorder diagnosis was most strongly associated with benzodiazepine use (AOR 3.42, 95% CI 2.28-5.13). DISCUSSION Illicit drug use is common among college students who screen positive for an eating disorder and report any lifetime eating disorder diagnosis. The co-occurring nature of eating disorders and illicit drug use may complicate treatment and lead to compounded adverse health outcomes.

Abstract
Purpose
Substance use disorder (SUD) frequently co-occurs with other psychological conditions, such as eating disorders (EDs). Psychological factors such as emotional dysregulation, rash impulsivity (RI) and reward sensitivity (RS) play a role in the etiology of each disorder, yet little is known about the combined effects of these on comorbid SUDs and EDs or disordered eating behaviours (DEBs). This study aims to examine the role of these psychological factors in comorbid DEBs and SUDs among individuals in treatment for SUDs. The role of gender is tested as a moderator.
Design/methodology/approach
A cross-sectional self-report survey was completed by 131 participants attending Australian residential substance use treatment centres. A binomial logistic regression analysis was performed to examine the effects of emotional dysregulation, RI and RS on comorbid DEB and SUD. Further, moderation analyses were used to examine the moderating effect for gender on the relationship between these three personality variables and comorbidity.
Findings
The most commonly reported primary substance of use was alcohol (43.5%), followed by amphetamines (38.6%). Findings showed that emotional dysregulation and RI were significantly related to an increase in comorbidity likelihood; however, RS was not. Gender moderated the relationship between comorbidity and RI only.
Originality/value
The significant positive relationship found between RI and comorbidity for females only was a novel finding for the current study. Further research is needed to develop an understanding of the etiology of comorbidity.

Abstract
The role of fear of missing out (FoMO) in addictive behaviors has recently attracted growing attention. In view of negative effects of gaming disorder (GD) among adolescents and emerging adults, research examining the relationship between FoMO and GD is needed, alongside the roles of impulsivity and gender in the relationship between FoMO and GD. This study examined whether impulsivity as a mediator and gender as a moderator impacted on the relationship between FoMO and GD among a sample of Chinese university students. A sample of 1,288 Chinese university students from three universities completed an online survey through the Wenjuanxing platform. The Chinese Trait-State Fear of Missing Out Scale, the Barratt Impulsiveness Scale-Brief, and the Chinese Gaming Disorder Scale were used in this study. The model results indicated that impulsivity partially mediated the relationship between FoMO and GD, and that there was a larger effect size between impulsivity and GD among males. High levels of FoMO among individuals may impact on executive functions leading to more impulsivity, and are associated with GD. Gender may moderate the relationship between impulsivity and GD. This study deepens the understanding of the relationship between FoMO and GD, and provides new perspectives for practitioners to incorporate into health prevention programs to help regulate emotion, control impulsivity, and decrease GD.

Abstract
OBJECTIVE Rumination, thinking about a negative mood repetitively, is a common cognitive process that may affect health behavior engagement or avoidance. Little research has examined relations between rumination and health behaviors. PURPOSE We aimed to test links between rumination and health behaviors as well as possible moderators and mediators of those links. METHODS We used an 11-day online daily diary design. Health behavior outcomes included fruit intake, vegetable intake, exercise, alcohol intake, sexual risk taking behavior, and cigarette smoking. RESULTS Rumination was related to alcohol intake at the within-person level. Using multivariate modeling, we found that significant within-person mediators for rumination to health behaviors included impulsivity, amotivation, self control, and using health behaviors as coping, with each of these mediating relationships for one to four out of the five health behavior outcomes. A significant between-person moderator includes perceived behavioral control for alcohol intake only, and intention was not a significant moderator of the rumination to health behavior relationships. CONCLUSIONS Rumination affects various maladaptive health behaviors differentially, through a number of mechanisms and under a moderating condition whereby those who feel more control are better able to buffer rumination's deleterious effects. Future interventions can apply the results to individual and multiple behavior change interventions for chronic disease prevention, especially for those who are particularly suffering from ruminative thoughts.

Abstract
Although evidence has shown that the prevalence rates of Internet gaming disorder (IGD) differ between males and females, few studies have examined whether such sex differences extend to brain function. This study aimed to explore the sex differences in resting-state cerebral activity alterations in IGD. Thirty male participants with IGD (IGDm), 23 female participants with IGD (IGDf), and 30 male and 22 female age-matched healthy controls (HC) underwent resting-state functional MRI. Maps of the amplitude of low-frequency fluctuation (ALFF) and functional connectivity (FC) were constructed. A two-factor ANCOVA model was performed, with sex and diagnosis as the between-subject factors. Then, post hoc pair-wise comparisons were performed using two-sample t-tests within the interaction masks. The Barratt Impulsiveness Scale-11 (BIS-11) was used to assess the behavioral inhibition function. We found that the ALFF values in the orbital part of the left superior frontal gyrus (SFG) were lower in IGDm than in HCm, which were negatively correlated with BIS-11 scores. IGDm also demonstrated lower connectivity between the orbital part of the left SFG and the posterior cingulate cortex (PCC), the right angular gyrus, and the right dorsolateral prefrontal cortex than HCm. Furthermore, IGDm had lower seed connectivity between the orbital part of the left SFG and the PCC than ICDf. Our findings suggest that (1) the altered ALFF values in the orbital part of the left SFG represent a clinically relevant biomarker for the behavioral inhibition function of IGDm; (2) IGD may interact with sex-specific patterns of FC in male and female subjects.

Abstract
BACKGROUND The purpose of this study was to examine the role of low self-control as a mediator or moderator between early age at sexual debut and risky sexual behavior in young adulthood. METHODS Data on 5734 male and female Add Health participants were used. Self-control (waves 1 & 3), age at sexual debut (wave 3) and risky sexual behavior (wave 4) were used in a structural equation modeling framework to assess the relationships of interest. RESULTS Approximately 17% of respondents were < 15 years at first sexual intercourse. Among females only, both early age at first intercourse (Parent-report: z = 5.08, p < .001; Self-report: z = 2.05, p < .05) and low self-control at wave 3 (Parent-report: z = 2.30, p < .05; Self-report: z = 2.31, p < .05) mediated the relationship between low self-control at wave 1 and risky sexual behaviors in young adulthood. Similarly in the male-only model, both early age at first intercourse (Parent-report: z = 2.92, p < .01; Self-report: z = 3.04, p < .01) and low self-control at wave 3 (Parent-report: z = 1.99, p < .05; Self-report: z = 3.15, p < .01) mediated the relationship between low self-control and risky sexual behaviors in young adulthood. There was evidence of moderation in the male-only model (- 0.26, p < .01), such that lower impulsivity strengthened the relationship between early sex and risky sex. CONCLUSIONS This study confirms the role of executive functions in sexual behaviors and suggests that interventions aimed at improving self-control may be beneficial in reducing risky sexual behavior.

Abstract
Alcohol consumption is a significant public health concern among young adults, with most recent research suggesting that the sex gap in alcohol consumption among young adults is closing. Thus, the present study tested sex as a moderator for known risk factors for alcohol use (impulsivity, sensation seeking, mindfulness). We examined sex differences by surveying young adults (n = 1,437) from across Washington state between 2011 and 2013 on alcohol risk factors (impulsivity, sensation seeking, mindfulness), alcohol consumption (quantity and frequency), and alcohol related negative consequences. Zero inflated Poisson and Zero inflated Negative Binomial models revealed that sex moderated the relationship between Peak Blood Alcohol Content (BAC) and impulsivity such that higher impulsivity was more strongly related to higher Peak BAC for women than for men. Overall, these results suggest that very few sex differences exist in alcohol consumption and alcohol-related negative consequences. Future research should look beyond the risk factors studied here to identify other important mechanisms that vary by sex that may be important targets for clinical or prevention efforts related to alcohol consumption.

Abstract
BACKGROUND Research has shown that some individuals can develop problematic patterns of online gaming, leading to significant psychological and interpersonal problems. Psychiatric distress and impulsivity have been suggested to contribute to problematic online gaming (POG). OBJECTIVE This study aimed to investigate the potential mediating or moderating mechanisms of impulsivity and gender-related differences in possible associations between psychiatric distress and POG. METHODS A total of 596 matched female and male participants, ranging in age from 14 to 38 years (mean 21.4, SD 4.5), were chosen from a large cross-sectional, nationwide Hungarian online gaming sample. Participants completed online questionnaires about self-reported impulsivity, psychiatric distress, and POG. RESULTS Psychiatric distress directly predicted POG, and impulsivity partially mediated the relationship between psychiatric distress and POG. However, this mediation effect was found only for the impatience factor of impulsivity. Impulsivity did not moderate the relationship between psychiatric distress and POG. A moderating effect of gender was not found in the direct relationship between psychiatric distress and POG. However, a moderated mediation analysis revealed that impatience mediated the association between psychiatric distress and POG in males, whereas the indirect effect of impatience was not significant in females. CONCLUSIONS The results of this work highlight gender-related difference among online gamers in the mediation effect of impulsivity between psychiatric distress and POG and provide novel insights regarding clinical implications for preventing or treating POG.

Abstract
Biases in outcome processing, mediated by the mesocortical dopaminergic (DA) system, may predict individual differences in the frequency and quantity of alcohol use. We tested the hypothesis that genetic markers associated with increased DA neurotransmission contribute to reduced neural sensitivity to costs and increased alcohol use in an undergraduate sample. We created a DA transmission score using five genetic markers related to DA transmission and assessed neural sensitivity to cost using the feedback-related negativity (FRN), an event-related potential implicated in neural outcome evaluation, on both passive evaluative and active decision-making tasks. Self-reported alcohol use was assessed using the Daily Drinking Questionnaire-Revised. Participants with a higher DA transmission score reported increased alcohol consumption and exhibited a more blunted FRN on both the passive and active tasks. While dopamine hyposensitivity is common among chronic alcohol users, these data provide preliminary evidence that hypersensitivity of the dopamine system may underlie increased alcohol use in those who have not yet developed a chronic alcohol use disorder.

Abstract
INTRODUCTION Non-cognitive skills, particularly in terms of risk-aversion, future-orientation, and conscientiousness, grow with age, and this phenomenon is known as personality maturation. However, significant variability in maturation among individuals exists. The technology of cognitive/non-cognitive skill formation suggests that the growth of non-cognitive skills is contingent on cognitive skills or human capital in general. The completion of formal education is a quintessential form of human capital. The aim of this study is to test whether formal education indeed facilitates the improvement of non-cognitive skills during early adulthood and adulthood.] METHODS: I used data from the National Longitudinal Study of Adolescent to Adult Health. The study sample consists of 9291 individuals, representative of U.S. adolescents in grades 7 through 12 in 1994. The longitudinal design of the data allowed the repeated measurement of their non-cognitive skills in adolescence (age < 18), early adulthood (between 18 and 25) and then in adulthood (>25). I used Latent Score Difference modeling to examine whether advancement in formal education through degree completion predicts within-individual change in non-cognitive skills in early adulthood and adulthood. RESULTS A steady increase in non-cognitive skills beyond adolescence was found. Independently of academic engagement during high school, parental socio-economic status, and adolescent non-cognitive skills, degree completion reported in early adulthood coincides with gains in non-cognitive skills since adolescence, and this positive feedback repeats itself in adulthood. CONCLUSIONS Continued schooling facilitates personality maturation beyond adolescence. Given the profound effects of non-cognitive skills on various life outcomes, educational opportunities could alleviate social stratification.

Abstract
To identify Gambling Disorder (GD) subtypes, in a population of men seeking treatment for GD, according to specific executive function domains (i.e., cognitive flexibility, inhibition and working memory as well as decision making) which are usually impaired in addictive behaviors. A total of 145 males ranging from 18 to 65 years diagnosed with GD were included in this study. All participants completed: (a) a set of questionnaires to assess psychopathological symptoms, personality and impulsivity traits, and (b) a battery of neuropsychological measures to test different executive functioning domains. Two clusters were identified based on the individual performance on the neuropsychological assessment. Cluster 1 [n = 106; labeled as Low Impaired Executive Function (LIEF)] was composed by patients with poor results in the neuropsychological assessment; cluster 2 patients [n = 46; labeled as High Impaired Executive Function (HIEF)] presented significantly higher deficits on the assessed domains and performed worse than the ones of LIEF cluster. Regarding the characterization of these two clusters, patients in cluster 2 were significantly older, unemployed and registered higher mean age of GD onset than patients in cluster 1. Additionally, patients in cluster 2 also obtained higher psychopathological symptoms, impulsivity (in both positive and negative urgency as well as sensation seeking) and some specific personality traits (higher harm avoidance as well as lower self-directedness and cooperativeness) than patients in cluster 1. The results of this study describe two different GD subtypes based on different cognitive domains (i.e., executive function performance). These two GD subtypes display different impulsivity and personality traits as well as clinical symptoms. The results provide new insight into the etiology and characterization of GD and have the potential to help improving current treatments.

Abstract
BACKGROUND Although there is considerable evidence of an association between impulsivity and cigarette smoking, the magnitude of this association varies across studies. Impulsivity comprises several discrete traits that may influence cigarette use in different ways. The present meta-analysis aims to examine the direction and magnitude of relationships between specific impulsivity-related traits, namely lack of premeditation, lack of perseverance, sensation seeking, negative urgency, positive urgency and reward sensitivity and both smoking status and severity of nicotine dependence in adults across studies and to delineate differences in effects across these relationships. METHODS Ninety-seven studies were meta-analysed using random-effects models to examine the relationship between impulsivity-related traits and smoking status and severity of nicotine dependence. A number of demographic and methodological variables were also assessed as potential moderators. RESULTS Smoking status and severity of nicotine dependence were significantly associated with all impulsivity-related traits except reward sensitivity. Lack of premeditation and positive urgency showed the largest associations with smoking status (r = 0.20, r = 0.24 respectively), while positive urgency showed the largest association with severity of nicotine dependence (r = 0.23). Study design moderated associations between lack of premeditation and lack of perseverance and smoking status, with larger effects found in cross-sectional compared to prospective studies. CONCLUSIONS Finding suggest that impulsivity is associated with an increased likelihood of being a smoker and greater nicotine dependence. Specific impulsivity-related traits differentially relate to smoking status and severity of nicotine dependence. Understanding the complexity of impulsivity-related traits in relation to smoking can help to identify potential smokers and could inform cessation treatment.

Abstract
INTRODUCTION This study examined gender differences in suicide attempts and their association with exposure and vulnerability to psychosocial, behavioral, and structural factors among Korean adolescents. METHODS Data of 74 854 adolescents, taken from the 2010 Korea Youth Risk Behavior Survey, were used. Logistic regression analysis was used to assess the contribution of differential exposure to psychosocial, behavioral, and structural factors for gender differences of suicidal attempt. RESULTS Gender differences were observed in the degree of exposure to the various factors. Females were more likely to report psychosocial problems, whereas males were more likely to report experience of smoking and drinking alcohol and to engage in vigorous physical activity. Stress and unhappiness were significantly associated with suicide attempts in both males and females, and gender differences in these variables were nonsignificant. Depressive symptoms were associated with a higher risk of suicide attempts, and this relationship was significantly stronger for males. The effects of cigarette smoking and risky drinking were significantly stronger in females. DISCUSSION Greater exposure to perceived stress, feelings of unhappiness, depression, and higher vulnerability of smoking and heavy drinking accounted for higher suicide attempts of female adolescents. Higher exposure to health-related behaviors and greater vulnerability to depressive symptoms in male were also noted. In conclusion, differences in exposure and vulnerability to psychosocial and behavioral factors may partly explain gender differences in suicide attempts among Korean adolescents.

Abstract
BACKGROUND AND AIMS Gambling disorder (GD) and alcohol use disorder (AD) have similar features, such as elevated impulsivity and decision-making deficits, which are directly linked to relapse and poor therapeutic outcomes. Our aim was to assess decision-making characteristics in GD and AD patients compared to healthy controls (HC) based on one of the most frequently used measures of decision-making: the Iowa Gambling Task (IGT). METHODS In our systematic literature search of three databases, we identified 1198 empirical articles that mentioned decision-making deficits with the use of the IGT in patients diagnosed with either AD or GD. Possible effects were calculated using meta-analysis. In the end, 17 studies (including 1360 participants) were suitable for inclusion in the meta-analysis reporting data for 23 group contrasts. RESULTS The random effects estimate indicated impaired IGT performance in both AD patients (N=500; d=-0.581, CI:-89.5<δ<-26.6%) and an even greater deficit in GD patients (N=292; d=-1.034, CI:-156.1<δ<50.7%) compared to HCs. Sampling variances were calculated for both AD (v1=0.0056) and GD groups (v2=0.0061), from which the z-score was calculated (z=-21.0785; p<0.05), which indicates a statistically significant difference between AD and GD groups. No significant moderating effects of age, gender or education were found. CONCLUSIONS There is enough evidence to support that decision-making deficit associated with addictive disorders, and that the deficit is more expressed in gambling disorder than in alcohol use disorder. Impaired decision-making plays an important part in poor therapeutic outcomes, thus provides a promising opportunity for cognitive intervention.

Abstract
Impulsiveness is a central human personality trait and of high relevance for the development of several mental disorders. Impulsiveness is a multidimensional construct, yet little is known about dimension-specific neural correlates. Here, we address the question whether motor, attentional and non-planning components, as measured by the Barratt Impulsiveness Scale (BIS-11), are associated with distinct or overlapping neural network activity. In this study, we investigated brain activity at rest and its relationship to distinct dimensions of impulsiveness in 30 healthy young adults (m/f = 13/17; age mean/SD = 26.4/2.6 years) using resting-state functional magnetic resonance imaging at 3T. A spatial independent component analysis and a multivariate model selection strategy were used to identify systems loading on distinct impulsivity domains. We first identified eight networks for which we had a-priori hypotheses. These networks included basal ganglia, cortical motor, cingulate and lateral prefrontal systems. From the eight networks, three were associated with impulsiveness measures (p < 0.05, FDR corrected). There were significant relationships between right frontoparietal network function and all three BIS domains. Striatal and midcingulate network activity was associated with motor impulsiveness only. Within the networks regionally confined effects of age and gender were found. These data suggest distinct and overlapping patterns of neural activity underlying specific dimensions of impulsiveness. Motor impulsiveness appears to be specifically related to striatal and midcingulate network activity, in contrast to a domain-unspecific right frontoparietal system. Effects of age and gender have to be considered in young healthy samples.

Abstract
Suicide is the second leading cause of death among adolescents, and impulsivity has emerged as a promising marker of risk. The present study tested whether distinct domains of impulsivity are differentially associated with suicide ideation, plans, and attempts. Adolescents (n = 381; boys = 106, girls = 275) aged 13-19 years (M = 15.62, SD = 1.41) were recruited from an acute, residential treatment program. Within 48 h of admission to the hospital, participants were administered structured clinical interviews assessing mental health disorders and suicidality. Following these interviews, participants completed self-report questionnaires assessing symptom severity and impulsivity. Consistent with past research, an exploratory factor analysis of our 90-item impulsivity instrument resulted in a three-factor solution: Pervasive Influence of Feelings, Feelings Trigger Action, and Lack of Follow-Through. Concurrent analysis of these factors confirmed hypotheses of unique associations with suicide ideation and attempts in the past month. Specifically, whereas Pervasive Influence of Feelings (i.e., tendency for emotions to shape thoughts about the self and the future) is uniquely associated with greater suicidal ideation, Feelings Trigger Action (i.e., impulsive behavioral reactivity to emotions) is uniquely associated with the occurrence of suicide attempts, even after controlling for current psychiatric diagnoses and symptoms. Exploratory gender analyses revealed that these effects were significant in female but not male adolescents. These findings provide new insight about how specific domains of impulsivity differentially increase risk for suicide ideation and attempts. Implications for early identification and prevention of youth suicide are discussed.

Abstract
AbstractEmerging developmental perspectives suggest that adverse rearing environments promote neurocognitive adaptations that heighten impulsivity and increase vulnerability to risky behavior. Although studies document links between harsh rearing environments and impulsive behavior on substance use, the developmental hypothesis that impulsivity acts as mechanism linking adverse rearing environments to downstream substance use remains to be investigated. The present study investigated the role of impulsivity in linking child abuse and neglect with adult substance use using data from (a) a longitudinal sample of youth (Study 1, N = 9,421) and (b) a cross-sectional sample of adults (Study 2, N = 1,011). In Study 1, the links between child abuse and neglect and young adult smoking and marijuana use were mediated by increases in adolescent impulsivity. In Study 2, indirect links between child abuse and neglect and substance use were evidenced via delayed reward discounting and impulsivity traits. Among impulsivity subcomponents, robust indirect effects connecting childhood experiences to cigarette use emerged for negative urgency. Negative urgency, positive urgency, and sensation seeking mediated the effect of child abuse and neglect on cannabis and alcohol use. Results suggest that child abuse and neglect increases risk for substance use in part, due to effects on impulsivity. Individuals with adverse childhood experiences may benefit from substance use preventive intervention programs that target impulsive behaviors.

Abstract
BACKGROUND Alcohol consumption and its related consequences are not equal for women and men, although related studies do not frequently include gender analysis. OBJECTIVE Our aim was to characterize differences in endorsement of ICD-10 and DSM 5 alcohol use disorder (AUD) criteria by gender in an Argentinean emergency department population. METHODS A probability sample of patients (N = 923) from the largest emergency department in the city of Mar del Plata, Argentina (44% were females, aged 16 to 86, M (SD) = 37.31(15.20) was collected. Using a structured questionnaire, diagnostic criteria for alcohol use disorders, alcohol consumption, and socio-demographic variables were obtained. Bivariate and multivariate analyses were used to assess differences in the endorsement of each diagnostic criterion by gender. RESULTS Women were less likely to endorse each of the criteria for each of the diagnostic schemes. Even after controlling alcohol consumption, socio-demographic variables, severity of alcohol use disorders and adjusting for multiple comparisons females had a lower probability than males of endorsing withdrawal and impaired control. CONCLUSIONS gender differences in the endorsement of diagnostic criteria for both the DSM 5 and ICD-10 were found. Some differences in endorsement but not all, might be partially explained by alcohol consumption patterns and socio-demographic factors, and same remained after controlling severity of the AUD. Results also suggest a differential functioning of DSM 5 and ICD-10 AUD criteria for women and men.

Abstract
The comorbidity between eating disorders (EDs) and substance use disorders (SUDs) is of particular concern given the high rates of mortality, relapse and poor treatment outcomes associated with both disorders. As a result, there has been a growing impetus within the field to elucidate factors that might influence and aid treatment for this comorbidity. One such factor is dispositional mindfulness, as past literature has demonstrated a significant relationship between mindfulness and both EDs and SUDs. However, we are unaware of any research that has examined the relationship between dispositional mindfulness and ED symptoms in a sample of men in residential treatment for SUDs. Medical records from 152 men were included in the current study. Alcohol and drug use and problems, ED symptoms, and dispositional mindfulness were assessed with self-report measures. Hierarchical regression analysis indicated that dispositional mindfulness was inversely related to ED symptoms after controlling for alcohol use, drug use, and age. Although results are preliminary and continued research in this area is needed, our findings suggest that there may be potential usefulness in targeting and enhancing mindfulness among patients in residential treatment for SUDs with co-occurring psychiatric symptoms (e.g., EDs).

Abstract
The amplitudes of the N2 and P3 components of event-related potentials (ERPs) may be influenced by personality traits such as impulsivity, and male/female differences may also have an effect. However, few studies have assessed the interaction between personality traits and the sex of the subject in these components. Therefore, in this study we evaluated sex differences in the amplitudes of the N2 and P3 ERP components during a continuous performance task, and their relation to impulse control. Twenty-seven healthy participants were asked to perform an AX-type continuous performance task, also known as a Go/Nogo task, during electroencephalographic recording. Participants then completed the Barratt impulsiveness scale (version 11; BIS-11), and the effortful control (EC) scale to self-report personality measures related to impulse control. We found that in the Nogo condition, males showed significantly larger N2 amplitudes than females in the frontal area. Interestingly, Nogo-N2 amplitudes were positively correlated with BIS-attentional subscale scores, but were negatively correlated with EC-attentional subscale scores, and both correlations were observed only in males. These results suggest that attentional aspects of impulse control modulate Nogo-N2 amplitude only in males. This modulatory effect may be related to a sex-specific inhibitory control mechanism acting during early stimulus evaluation.

Abstract
Water quality is an important determinant of diarrheal illnesses, especially affecting children in sub-Saharan Africa. Orphans and vulnerable children (OVC) in sub-Saharan Africa are at increased risk of poor quality drinking water, and therefore of diarrheal illness. The present study assesses primary drinking water source and typical household water purification among OVC households involved in a multi-sectoral empowerment program in semi-rural Kenya. Findings show water purification practices, but not water source, significantly increase with more time in the program. Other factors associated with safer water include household income, orphan type, food consumption and security, school completion, psychological resilience, engaging in sexual intercourse with more than one partner in the past 12 months, and previous year's financial status. Incorporating water quality improvements in a community-based empowerment program such as the one described may be one method of improving water quality and decreasing diarrheal illnesses among OVCs in sub-Saharan Africa.

Abstract
Methamphetamine (METH) is an addictive stimulant, and METH users have abnormal brain structures and function. The aims of this study were to investigate the relationships between impulsivity, brain structures, and possible sex-specific differences between METH users and non-drug using Controls. Structural MRI and the Barratt Impulsiveness Scale (BIS) questionnaire were completed in 124 subjects: 62 METH (ages 41.2 ± 1.4 years, 34 males) and 62 Controls (ages 43.3 ± 2.3 years, 36 males). Independent and interactive effects of METH use status and sex were evaluated. Relationships between METH usage characteristics, brain morphometry, and impulsivity scores were examined. METH users had higher impulsivity scores, on both the Cognitive and Behavioral Factors from the BIS (p < 0.0001-0.0001). Compared with same-sex Controls, male METH users had larger, while female METH users had smaller, right superior frontal cortex (interaction-p = 0.0005). The male METH users with larger frontal volumes and female METH users with smaller or thinner frontal cortices had greater Cognitive impulsivity (interaction-p ≤ 0.05). Only female METH users showed relatively larger nucleus accumbens (interaction-p = 0.03). Greater impulsivity and thinner frontal cortices in METH users are validated. Larger superior frontal cortex in male METH users with greater cognitive impulsivity suggest decreased dendritic pruning during adolescence might have contributed to their impulsive and drug use behaviors. In the female METH users, smaller frontal cortices and the associated greater impulsivity suggest greater neurotoxicity to these brain regions, while their relatively larger nucleus accumbens suggest an estrogen-mediated neuroprotective glial response. Men and women may be affected differently by METH use.

Abstract
BACKGROUND Numerous studies have demonstrated that trait impulsivity is linked to increased risk of developing alcohol-use disorders and other substance abuse. Impulsivity has also been shown in some studies to potentiate cue-induced drug cravings. Despite considerable evidence of gender differences in impulsivity and drug craving among individuals suffering from alcohol dependence and other drug use, little research has focused on these processes in healthy young men and women who may be at risk for developing alcohol-use disorders. The objective of this study was to investigate the relationship between impulsivity and cue-induced craving, as well as possible gender differences in these effects among healthy young adults. METHODS To that end, female (n = 22) and male (n = 14) social drinkers aged 18 to 25, recruited from an urban university campus, completed the Barratt Impulsiveness Scale and reported their alcohol cravings immediately before and after laboratory exposure to alcohol cues. RESULTS Findings indicated that exposure to cues elicited increased alcohol cravings, but these effects did not differ by gender. Interestingly, a significant interaction of impulsivity and gender revealed that impulsivity predicted significantly higher cue-induced cravings in women, but not men. CONCLUSIONS Findings underscore the importance of better understanding the interaction of situational factors (e.g., exposure to alcohol cues) and dispositional factors (e.g., impulsivity) as potential contributors to drinking motivation. Future prospective research is needed to identify gender-specific risk factors for the development of problem drinking.

Abstract
BACKGROUND Individuals at high risk to develop alcoholism often manifest neurocognitive deficits as well as increased impulsivity. Event-related oscillations (EROs) have been used to effectively measure brain (dys)function during cognitive tasks in individuals with alcoholism and related disorders and in those at risk to develop these disorders. The current study examines ERO theta power during reward processing as well as impulsivity in adolescent and young adult subjects at high risk for alcoholism. METHODS EROs were recorded during a monetary gambling task (MGT) in 12-25 years old participants (N = 1821; males = 48%) from high risk alcoholic families (HR, N = 1534) and comparison low risk community families (LR, N = 287) from the Collaborative Study on the Genetics of Alcoholism (COGA). Impulsivity scores and prevalence of externalizing diagnoses were also compared between LR and HR groups. RESULTS HR offspring showed lower theta power and decreased current source density (CSD) activity than LR offspring during loss and gain conditions. Younger males had higher theta power than younger females in both groups, while the older HR females showed more theta power than older HR males. Younger subjects showed higher theta power than older subjects in each comparison. Differences in topography (i.e., frontalization) between groups were also observed. Further, HR subjects across gender had higher impulsivity scores and increased prevalence of externalizing disorders compared to LR subjects. CONCLUSIONS As theta power during reward processing is found to be lower not only in alcoholics, but also in HR subjects, it is proposed that reduced reward-related theta power, in addition to impulsivity and externalizing features, may be related in a predisposition to develop alcoholism and related disorders.

Abstract
Previous research has suggested that problematic Internet use (PIU) is associated with impulse control disorder. Although researchers have suggested that impulsivity is a risk factor for PIU, the literature lacks longitudinal evidence on the relationship between impulsivity and PIU. We aimed to use a cross-lagged analytic framework to identify temporal order effects and hypothesised that impulsivity was the precedent factor for PIU. In a panel sample of college students (N = 367), trait impulsivity and PIU were measured in the spring of freshman year and in their junior year. The measures included a self-developed PIU Scale and the revised Impulsiveness Scale based on Barratt's concept. We found that "non-planning impulsivity" was not associated with PIU. The "motor impulsivity" subfactor was thus adopted in the cross-lagged model. The results suggest that motor impulsivity and PIU were stable across time. Motor impulsivity at Time 1 positively predicted PIU at Time 2, but PIU at Time 1 did not predict motor impulsivity at Time 2. A further investigation using gender as a moderator found a gender difference in the temporal relationship. Because motor impulsivity is a risk factor for PIU, potential prevention strategies based on this result are suggested.

Abstract
BACKGROUND Individuals at high risk to develop alcoholism often manifest neurocognitive deficits as well as increased impulsivity. The goal of the present study is to elucidate reward processing deficits, externalizing disorders, and impulsivity as elicited by electrophysiological, clinical and behavioral measures in subjects at high risk for alcoholism from families densely affected by alcoholism in the context of brain maturation across age groups and gender. METHODS Event-related potentials (ERPs) and current source density (CSD) during a monetary gambling task (MGT) were measured in 12-25 year old offspring (N=1864) of families in the Collaborative Study on the Genetics of Alcoholism (COGA) Prospective study; the high risk (HR, N=1569) subjects were from families densely affected with alcoholism and the low risk (LR, N=295) subjects were from community families. Externalizing disorders and impulsivity scores were also compared between LR and HR groups. RESULTS HR offspring from older (16-25 years) male and younger (12-15 years) female subgroups showed lower P3 amplitude than LR subjects. The amplitude decrement was most prominent in HR males during the loss condition. Overall, P3 amplitude increase at anterior sites and decrease at posterior areas were seen in older compared to younger subjects, suggesting frontalization during brain maturation. The HR subgroups also exhibited hypofrontality manifested as weaker CSD activity during both loss and gain conditions at frontal regions. Further, the HR subjects had higher impulsivity scores and increased prevalence of externalizing disorders. P3 amplitudes during the gain condition were negatively correlated with impulsivity scores. CONCLUSIONS Older male and younger female HR offspring, compared to their LR counterparts, manifested reward processing deficits as indexed by lower P3 amplitude and weaker CSD activity, along with higher prevalence of externalizing disorders and higher impulsivity scores. SIGNIFICANCE Reward related P3 is a valuable measure reflecting neurocognitive dysfunction in subjects at risk for alcoholism, as well as to characterize reward processing and brain maturation across gender and age group.

Abstract
OBJECTIVE We investigated relationships among gender, impulsivity and disordered eating in healthy college students. METHOD Participants (N=1223) were healthy, undergraduate men (28.5%) and women (71.5%), who completed the Barratt Impulsiveness Scale - Version 11 (BIS-11) and a four-factor version of the Eating Attitudes Test (EAT-16). RESULTS As predicted, mean scores on all four EAT-16 factors were significantly higher for women than for men. Attentional impulsivity was related to poorer self-perception of body shape, more dieting, and a greater preoccupation with food for the sample as a whole. Moreover, motor impulsivity was related to poorer self-perceptions of body shape and a greater preoccupation with food. However, no gender differences emerged in the relationship between impulsivity and disordered eating attitudes. DISCUSSION This study elucidates the role of impulsivity in disordered eating behaviors among non-clinical college students. For both women and men, attentional and motor impulsivity were related to disordered eating attitudes and behaviors. Overall, these findings suggest that different facets of impulsivity are related to disordered eating attitudes and behaviors in a non-clinical college population.

Abstract
Many college students are involved in gambling behavior as a recreational activity. Their involvement could potentially develop into problem gambling, an issue of increasing concern to student health. At the same time, evidence suggests that Asian Americans are overrepresented amongst problem gamblers in this age period. Research on factors related to initiation and development of problem gambling in college students is necessary to inform the development of effective and culturally-sensitive prevention efforts against gambling. The relationships between personal gambling expectancies at two levels of specificity (two general and six specific types of expectancies) and college student gambling at two levels of behavior (initiation and problems) were examined in a sample of 813 Asian American and White American college students. The study aimed to address (a) whether expectancies explained ethnic differences in gambling, (b) ethnic similarities and differences in the pattern of relationships between expectancies and gambling, and (c) whether expectancies that emerged in both ethnic groups have a greater risk or protective effect for one group than another. Results showed that Asian American students reported more problem gambling than White American students, but expectancies did not account for this group difference. Risk and protective factors for initiation were relatively similar between groups, but different patterns of risk emerged for each group for problem gambling. Implications for college primary prevention and harm reduction programs are discussed.
