The contributions of risk-taking and impulsivity to jumping to conclusions in the psychosis spectrum.

The jumping to conclusions (JTC) bias has been linked to the formation and maintenance of delusions across the psychosis spectrum. However, it remains unclear whether this bias reflects a primary cognitive deviation or is secondary to other cognitive processes. To this end, we investigated the relationship between JTC, risk-taking, impulsivity, and sensation seeking in individuals with psychotic-like experiences (PLEs) and controls. A large online community sample (N = 1151) completed the Fish Task as a measure for the JTC bias, as well as the Balloon Analogue Risk Task (BART) and the Brief Risk-Taking Propensity Scale (R-1) as measures of the propensity to take risks. Measures assessing impulsivity (Impulsive Behavior Scale-8, I-8), sensation seeking (Brief Sensation Seeking Scale, BSSS-4), and verbal intelligence (12-item Wordsum test) were also administered. We dichotomized the sample into extreme groups based on the positive subscale of the Community Assessment of Psychotic Experiences (CAPE). The present study confirms the existence of a JTC bias in psychosis-prone individuals. Of note, PLE-high individuals self-reported higher risk-taking propensity in the R-1 while at the same time displaying higher objective risk aversion in the BART relative to controls, speaking for a dissociation of subjective versus objective risk-taking behavior. PLE-high individuals showed deviances in other psychological traits (impulsivity, sensation seeking), but these were not associated with hasty decision-making as measured by JTC or risk-taking propensity. The results speak against impulsivity, sensation seeking, or verbal intelligence as driving mechanisms of JTC and risky decision-making.

Simultaneous Substance Use With Alcohol in a Community-Based Sample of Young Adults.

Objective: Simultaneous substance use is associated with worse outcomes than concurrent use. Further investigations into simultaneous use are warranted because there is limited knowledge about the co-use of substances other than alcohol and cannabis. Study aims were to examine: (1) the prevalence of simultaneous use of substances with alcohol, (2) the extent to which use patterns are related to key correlates (i.e., psychological functioning, sensation seeking), and (3) differences by college status. Methods: Participants were 623 young adult drinkers who were recruited online to complete a one-time survey. Results: Cannabis (54.3%), tobacco (53.7%), and stimulants (46.5%) were most frequently used with alcohol. Moderation analyses showed the positive association between simultaneous use and psychological distress was stronger for students whereas the positive association with sensation seeking was stronger for nonstudents. Conclusions: Results highlight the need for future research and intervention efforts that consider the link between simultaneous use and psychological wellbeing while acknowledging that educational attainment may differentially influence these factors.

Stressful Life Events, Sleep Quality and Non-Suicidal Self-Injury in Chinese Adolescents: The Moderating Effect of Sensation Seeking.

Despite the growing evidence that stressful life events are associated with adolescent non-suicidal self-injury (NSSI), few studies have investigated the mediating and moderating mechanisms underlying this link. The current study examined whether sleep quality mediated the link between stressful life events and NSSI and whether this mediating process was moderated by adolescent sensation seeking. The participants were 1006 Chinese adolescents (48.21% boys; mean age = 13.16 years, SD = 0.67). They completed the Life Events Checklist, Pittsburgh Sleep Quality Index, UPPS-P Impulsive Behavior Scale, and NSSI Questionnaire. The PROCESS macro for SPSS was used to examine the hypothesized moderated mediation model. The results showed that sleep quality significantly mediated the positive association between stressful life events and adolescent NSSI. Moreover, this mediating pathway was moderated by sensation seeking. Specifically, the risk impact of stressful life events on NSSI through sleep quality was significant only among adolescents with high-level sensation seeking but not among those with low-level sensation seeking. These findings provide intervention insights to reduce the risk of adolescent NSSI.

Does sensation-seeking behavior influence the patterns of flavored e-cigarette use? A cross-sectional study among Indonesian adolescents and young adults.

BACKGROUND: The variety of available flavors in e-cigarettes may be a driver for young people to start using these products. The objectives of our study were to examine the relationship between sensation-seeking behavior and e-cigarette use, and to identify the predictors of flavor use patterns among adolescents in Indonesia. METHODS: Students aged 15 to 24 years participated from randomly selected high schools and universities in Indonesia. Participants answered questions about their demographic data, e-cigarette use, conventional cigarette use, and sensation-seeking. Flavor preferences were identified from eight different flavor categories. Multivariate multinomial regression analysis was employed to predict conventional cigarette and e-cigarette use among students. A latent class analysis was conducted to determine the number of latent classes of flavor use. RESULTS: One thousand six hundred high school and university students, with a mean age of 18.2 years (SD 2.19), were recruited between March and August, 2023. Conventional cigarette use in the past 30 days was higher (16.3%) compared to e-cigarette use (13.3%, p = 0.017), with approximately 8.5% of students were being dual users. Higher levels of sensation-seeking significantly increased the odds of being a current e-cigarette user (OR = 2.54, 95%CI 1.99-3.25) and a current conventional cigarette smoker (OR = 2.38, 95%CI 1.85-3.07). Three groups of flavor classes were identified: 1) primarily menthol flavor users (14%), who had a strong association with current conventional cigarette use; 2) experimenters, who mostly preferred fruit-flavored e-cigarettes (76%); and 3) the multi-flavor user group (10%), who had a higher sensation-seeking tendency. CONCLUSIONS: Flavors, especially menthol and fruit flavors, attract youth, broaden the e-cigarette audience and are particularly appealing to high sensation-seekers. Banning these flavors could significantly deter e-cigarette initiation among youth.

Testing the Factor Structure and Construct Validity of the German Version of Gray et al.'s (2003) Sexual Fantasy Questionnaire.

Gray et al.'s (2003) Sexual Fantasy Questionnaire (SFQ) is becoming an increasingly used self-report measure of sexual fantasy use. The current study analyzed the factorial structure and construct validity of the behavioral items of the SFQ using a nomological network of other sexuality-related measures in a large German-speaking sample (N = 846). Participants' (27.7% females) mean age was 30.8 years (SD = 11.0). Exploratory factor analysis revealed a 65-item scale comprising five-factors, which were termed: normophilic sexual fantasies, sexualized aggression, sexualized submission, submissive courtship, and bodily functions. This German version of the SFQ was found to have high construct validity indicated by its association with other related constructs. Based on these results, we argue that the SFQ is a valid self-report measure that can be used in both research and clinical practice (foremost the factors sexualized aggression and sexualized submission). Suggestions for future research are discussed in light of the results and the study's limitations.

Uncontrolled eating is associated with higher impulsiveness, risk taking and novelty-seeking.

Previous studies suggest that trait disinhibition as measured by the Three Factor eating Questionnaire (TFEQ) is related to selected measures of impulsivity and risk taking. However, the factor validity of the original trait disinhibition measure has been questioned, and a revised scale of uncontrolled eating consequently developed. To date few studies have revisited the relationship between impulsivity and the uncontrolled and emotional eating scales of the revised TFEQ. In the present study, 283 participants (208 women) completed the revised TFEQ alongside a battery of measures of impulsivity and risk taking in an online study. The total and all subscale scores on the Barratt Impulsiveness Scale were significantly associated with scores on the uncontrolled, but not emotional or restrained, TFEQ scale. Likewise, risky behaviour indexed by the average number of pumps per trial on the Balloon Analogue Risk Task were also associated with uncontrolled, but not emotional or restrained, eating, and the same pattern of associations were also found for the novelty, but not intensity, subscales of the Arnetts Inventory of Sensation Seeking. Overall these data suggest that uncontrolled eating is related to wider personality traits of risky decision making, novelty seeking and wider cognitive impulsivity, which may in turn increase of future weight gain.

The role of parental maladaptive emotion socialization in the risk process for negative urgency and drinking behavior in adolescence.

INTRODUCTION: Negative urgency (the tendency to act rashly when experiencing negative emotions) is a robust risk factor for a number of problem behaviors, including early adolescent drinking. Little is known about the factors that precede the development of negative urgency, and hence the full etiology of this component of risk. The current study aimed to investigate the possibility that facets of childhood maladaptive emotion socialization (the tendency for children's expressions of emotions to be met with punishment, minimized, or invoke a reaction of distress from their parents/caretakers) increases risk for the development of negative urgency and drinking behavior. METHOD: Self-report measures of negative urgency, subfacets of maladaptive emotion socialization, and drinking behavior were collected during the 2021-2022 academic year from a sample of 428 high school students (mean age = 14.7, SD = 0.09, 44% female), assessed twice over the course of a semester, reflecting a 4-month longitudinal window. RESULTS: Distress emotion socialization predicted increases in negative urgency, minimizing predicted decreases in negative urgency, and punitive did not provide significant prediction. Additionally, results found that higher levels of both negative urgency and distress emotion socialization increased adolescents' likelihood of having tried alcohol. These processes were invariant across race and gender. CONCLUSIONS: The present study may inform the future creation of prevention and intervention efforts aimed at reducing maladaptive emotion socialization and increasing adaptive emotion socialization. Successful reductions in negative urgency as a consequence of increased adaptive emotion socialization may then lead to decreases in adolescent drinking and other impulsigenic behaviors.

Childhood maltreatment and NSSI in prisoners: mediation through self-identity and moderation by sensation-seeking.

Introduction: The prevalence of non-suicidal self-injury (NSSI) among prisoners is widely recognized. However, most research conducted in prisons setting has focused on lifetime engagement in NSSI, with limited knowledge about its correlates and risk factors during imprisonment. Methods: Drawing on the integrated theoretical model of NSSI, this study aimed to examine the combined effects of childhood maltreatment (an environmental factor) and two intrapersonal factors, namely self-identity and sensation-seeking, on NSSI. 1042 Chinese male offenders participated in the current study, and regression analyses is used to examine the relationship among variables. Results: The results revealed that self-identity mediated the association between childhood maltreatment and prisoners' NSSI. Sensation-seeking moderated the relationship between self-identity and NSSI, and this connection was only significant for offenders with high sensation-seeking. Discussion: We discuss the results of the current research and possible practical implications.

Too Tired to Think: Within and Between-Person Relations Among Impulsive Traits, Sleep Duration, and Mental Health Outcomes.

Heavier drinking and depression are common mental health concerns in the USA, yet few studies have sought to understand transdiagnostic risk factors for both. Two health-focused risk factors are impulsive personality traits and sleep duration, but research typically separates the two, precluding additive and interactive relations. The current study sought to test a theoretical model where risk conferred from impulsive traits is heightened when individuals have reduced sleep. Public-access data from the National Longitudinal Study on Adolescent to Adult Health (Add Health) were used to test study hypotheses. Participants reported on impulsive traits (i.e., lack of premeditation, sensation seeking), sleep duration, depression, and drinking across three waves spanning adolescence, emerging adulthood, and adulthood. Multilevel models distinguished risk processes at the between- vs. within-person level. At the between-person level, sensation seeking predicted drinking whereas premeditation predicted depression. Additionally, within-person deviations in both traits were associated with drinking, whereas within-person deviations in premeditation were associated with depression. Sleep duration was protective against outcomes at both levels. However, main effects were qualified by interactions at both levels, such that having below average sleep duration heightened the effects of premeditation at the between-person level, whereas within-person decreases in sleep heightened the effects of sensation seeking at the within-person level. Findings support a theoretical model where poor sleep exacerbates risk conferred from impulsive traits. Risk conferred from impulsive traits diverged based upon level of analysis, suggesting that global and just-in-time interventions may benefit from targeting specific impulsive traits as well as sleep.

Neurogenetic and multi-omic sources of overlap among sensation seeking, alcohol consumption, and alcohol use disorder.

Sensation seeking is bidirectionally associated with levels of alcohol consumption in both adult and adolescent samples, and shared neurobiological and genetic influences may in part explain these associations. Links between sensation seeking and alcohol use disorder (AUD) may primarily manifest via increased alcohol consumption rather than through direct effects on increasing problems and consequences. Here the overlap among sensation seeking, alcohol consumption, and AUD was examined using multivariate modelling approaches for genome-wide association study (GWAS) summary statistics in conjunction with neurobiologically informed analyses at multiple levels of investigation. Meta-analytic and genomic structural equation modelling (GenomicSEM) approaches were used to conduct GWAS of sensation seeking, alcohol consumption, and AUD. Resulting summary statistics were used in downstream analyses to examine shared brain tissue enrichment of heritability and genome-wide evidence of overlap (e.g., stratified GenomicSEM, RRHO, genetic correlations with neuroimaging phenotypes), and to identify genomic regions likely contributing to observed genetic overlap across traits (e.g., H-MAGMA and LAVA). Across approaches, results supported shared neurogenetic architecture between sensation seeking and alcohol consumption characterised by overlapping enrichment of genes expressed in midbrain and striatal tissues and variants associated with increased cortical surface area. Alcohol consumption and AUD evidenced overlap in relation to variants associated with decreased frontocortical thickness. Finally, genetic mediation models provided evidence of alcohol consumption mediating associations between sensation seeking and AUD. This study extends previous research by examining critical sources of neurogenetic and multi-omic overlap among sensation seeking, alcohol consumption, and AUD which may underlie observed phenotypic associations.

Longitudinal associations between loneliness and online game addiction among undergraduates: A moderated mediation model.

Online gaming addiction (OGA) has become a noteworthy public concern, especially among university students, thereby requiring in-depth scrutiny. Although previous cross-sectional studies have established a positive link between loneliness and OGA, there is a lack of longitudinal evidence within this field. Moreover, the underlying mechanisms that elucidate the connection between loneliness and OGA are still poorly understood, underscoring a crucial research gap that requires further investigation. Our study utilized a longitudinal approach and developed a moderated mediation model. From September 2021 to September 2022, during the COVID-19 pandemic, data were collected from a sample of Chinese undergraduate students, with 367 participants at T1, 352 at T2, and 340 at T3. Participants completed online self-report surveys, providing valuable data on their levels of loneliness at T1, fear of missing out (FoMO) at T2, sensation seeking at T2, and OGA at T3. Our findings found that loneliness was positively linked to OGA. Further analysis demonstrated that FoMO partially mediated the link between loneliness and OGA. Meanwhile, sensation seeking moderated the pathway from FoMO to later OGA. Specifically, the effect of FoMO on OGA was significant for college students with high sensation seeking. This study offers longitudinal evidence linking loneliness and OGA, which has implications for the development of interventions to reduce OGA.

Hooked on technology: examining the co-occurrence of nomophobia and impulsive sensation seeking among nursing students.

BACKGROUND: Nomophobia, the crippling fear of being disconnected from mobile devices, is a burgeoning global concern. Given the critical nature of the profession of nursing students, understanding nomophobia's prevalence and potential impacts on patient care and professional conductors becomes even more crucial. AIM: This study explores the relationship between nomophobia and impulsive sensation-seeking among nursing students in Egypt. DESIGN AND METHODS: A multicenter cross-sectional survey was conducted with 1626 nursing students randomly selected from three universities across Egypt. TOOLS: The Arabic versions of the Nomophobia and Impulsive Sensation Seeking Questionnaires were employed to gather data. RESULTS: Our findings revealed that 40.3% of the surveyed nursing students exhibited severe nomophobia, indicating a substantial dependence on their mobile devices. Notably, this high prevalence was accompanied by a strong tendency towards impulsive sensation-seeking behaviors. Furthermore, a stepwise regression analysis identified several significant predictors of nomophobia (p < 0.001). Impulsive sensation-seeking, year of study, average daily smartphone usage, and age emerged as key factors, explaining 27.5% of the variability in nomophobia scores. CONCLUSION: The prevalence of nomophobia among Egyptian nursing students is undeniable, highlighting their substantial reliance on mobile devices. A significant association with impulsive sensation-seeking behavior further compounds this dependence. Factors such as impulsive sensation seeking, year of study, average daily smartphone usage, and age were identified as significant predictors of nomophobia. Recognizing these factors as key predictors of nomophobia is crucial for designing effective interventions and psychotherapies. Prioritizing such interventions can promote future nurses' well-being and ensure they deliver the highest quality care to their patients.

The Mediating Effect of Danger Invulnerability in the Relationship Between Sensation Seeking and Gambling Among University Students.

The association between sensation-seeking and gambling is well established, yet the research on mediators of this relationship is limited. The proposed model of the present study includes sensation seeking as an antecedent variable, danger invulnerability as a mediator, and gambling frequency as an outcome variable.Self-report data obtained from a convenient sample of 641 university students aged 18-40 years (Mage = 21.25; F = 52.7%, M = 47.3%) were analysed. This study supported proposed hypothesis that both sensation seeking and danger invulnerability are in significant positive relation with the frequency of gambling. Moreover, the results show that tested mediation model fit the data well, and that danger invulnerability completely mediates the relationship between sensation seeking and gambling frequency, such that higher sensation seeking is related to higher danger invulnerability and higher danger invulnerability is related to higher gambling frequency. The model explained 42.4% of the variance in danger invulnerability and 32.7% of the variance in gambling frequency. This study underscores the importance of examining both the direct and indirect effects of different variables on gambling behaviour.

Toxic sensation seeking? Psychological distress, cyberbullying, and the moderating effect of online disinhibition among adults.

Cyberbullying among adults is barely studied, though its consequences may be as severe as in children and adolescents. The present study investigated the links between psychological distress, cyber-perpetration, and passive cyber-bystander behavior. We also explored the moderating role of toxic disinhibition in this regard. Our sample comprised 385 adults aged 19-66 (M = 28.35, SD = 11.22, 76.62% females). The results suggested that psychological distress was significantly associated with cyberbullying perpetration and passive bystander behavior. Also, higher psychological distress significantly predicted toxic disinhibition. Further moderation analyses suggested that at high and medium levels of toxic disinhibition, psychological distress significantly predicted cyberbullying perpetration but not passive cyber-bystander behavior. Finally, we discuss our results regarding their theoretical and practical implication for cyberbullying prevention among adults.

Effects of hazards and sensation-seeking on intermediate swimming college students' hazard perceptions.

BACKGROUND: According to the Global Report on Drowning: Preventing a Leading Killer and Preventing Drowning: An Implementation Guide, two documents released by the World Health Organization in 2014 and 2017, respectively, 372,000 people drown each year globally (approximately 42 per hour), half of whom are below 25 years old. Chinese adolescents aged 18-24 years are the main victim group. Intermediate swimming college students are more susceptible to risk-taking behavior and drowning while swimming. In particular, college students with high-sensation-seeking levels have greater confidence in their swimming ability. Consequently, they tend to overestimate their skills and pursue exciting experiences while underestimating or ignoring the risk factors in the situation. The scores of college students in sensation-seeking show a significant positive correlation with highly risky swimming behavior. However, the correlation with the reaction time to hazards is unclear. In this study, using previous theories, the sensation-seeking scale, and the measurement of the reaction time to hazards, we clearly explain why "college students with higher levels of sensation-seeking have a higher risk of drowning." We examined the reaction time to hazards and eye movement data of intermediate swimming college students with different sensation-seeking levels, while controlling the obviousness of hazards in the videos for the experiment. METHODS: We utilized 16 videos of students swimming as experimental stimuli and employed a mixed experimental design of 2 (sensation-seeking: high, low) × 2 (hazard type: obvious hazard, hidden hazard). Sensation-seeking, the between-subjects variable, was categorized into two levels (high and low). The hazard type, the within-subjects variable, was also divided into two categories (obvious and hidden). We analyzed the disparities in reaction time to hazards and eye-movement data between intermediate swimming college students with high (N = 28) or low (N = 28) levels of sensation-seeking. RESULTS: Intermediate swimming college students with high levels of sensation-seeking exhibited significantly longer reaction times to both obvious (F = 6.251, p = .000 < .001) and hidden (F = 49.438, p = .000 < .001) hazards compared to their low-sensation-seeking counterparts. The first fixation duration of intermediate swimming college students on obvious hazards was shorter than that on hidden hazards (F = 13.596, p = .000 < .001), and the average fixation duration of intermediate swimming college students with high levels of sensation-seeking on hidden hazards proved to be significantly shorter (F = 5.498, p = .000 < .001). CONCLUSIONS AND IMPLICATIONS: High-sensation-seeking intermediate swimming college students exhibited longer reaction times to hidden hazards compared to their low-sensation-seeking peers. These findings indicate that a high-sensation-seeking tendency can result in delayed reaction times and a disregard for response measures among intermediate swimming college students.

Electrocortical correlates of hypersensitivity to large immediate rewards in sensation seeking.

Sensation seeking and delay discounting are strong predictors of various risk-taking behaviors. However, the relationship between sensation seeking and delay discounting remains elusive. Here, we addressed this issue by examining how high sensation seekers (HSS; N = 40) and low sensation seekers (LSS; N = 40) evaluated immediate and delayed rewards with low and high amounts during a behavioral task and an EEG task of delay discounting. Although HSS and LSS exhibited comparable discounting preference at the behavioral level, HSS relative to LSS was associated with a greater delay discounting effect at the neural level when earned rewards were large. This abnormality of reward magnitude was further corroborated by an electrocortical hypersensitivity to large immediate rewards and a stronger neural coding of reward magnitude for HSS as compared to LSS. Our findings support both the hyperactive approach theory and the optimal arousal theory in sensation seeking and have implications for the prevention and intervention targeting sensation seeking to reduce maladaptive risk-taking behaviors.

Sensation seeking correlates with increased white matter integrity of structures associated with visuospatial processing in healthy adults.

Introduction: The ability to process sensory information is an essential adaptive function, and hyper- or hypo-sensitive maladaptive profiles of responses to environmental stimuli generate sensory processing disorders linked to cognitive, affective, and behavioral alterations. Consequently, assessing sensory processing profiles might help research the vulnerability and resilience to mental disorders. The research on neuroradiological correlates of the sensory processing profiles is mainly limited to the young-age population or neurodevelopmental disorders. So, this study aims to examine the structural MRI correlates of sensory profiles in a sample of typically developed adults. Methods: We investigated structural cortical thickness (CT) and white matter integrity, through Diffusion Tensor Imaging (DTI), correlates of Adolescent/Adult Sensory Profile (AASP) questionnaire subscales in 57 typical developing subjects (34F; mean age: 32.7 ± 9.3). Results: We found significant results only for the sensation seeking (STS) subscale. Positive and negative correlations emerged with fractional anisotropy (FA) and radial diffusivity (RD) in anterior thalamic radiation, optic radiation, superior longitudinal fasciculus, corpus callosum, and the cingulum bundle. No correlation between sensation seeking and whole brain cortical thickness was found. Discussion: Overall, our results suggest a positive correlation between sensation seeking and higher white matter structural integrity in those tracts mainly involved in visuospatial processing but no correlation with gray matter structure. The enhanced structural integrity associated with sensation seeking may reflect a neurobiological substrate linked to active research of sensory stimuli and resilience to major psychiatric disorders like schizophrenia, bipolar disorder, and depression.

Uncontrolled eating and sensation-seeking partially explain the prediction of future binge drinking from adolescent brain structure.

Binge drinking behavior in early adulthood can be predicted from brain structure during early adolescence with an accuracy of above 70%. We investigated whether this accurate prospective prediction of alcohol misuse behavior can be explained by psychometric variables such as personality traits or mental health comorbidities in a data-driven approach. We analyzed a subset of adolescents who did not have any prior binge drinking experience at age 14 (IMAGEN dataset, n = 555, 52.61% female). Participants underwent structural magnetic resonance imaging at age 14, binge drinking assessments at ages 14 and 22, and psychometric questionnaire assessments at ages 14 and 22. We derived structural brain features from T1-weighted magnetic resonance and diffusion tensor imaging. Using Machine Learning (ML), we predicted binge drinking (age 22) from brain structure (age 14) and used counterbalancing with oversampling to systematically control for 110 + variables from a wide range of social, personality, and other psychometric characteristics potentially associated with binge drinking. We evaluated if controlling for any variable resulted in a significant reduction in ML prediction accuracy. Sensation-seeking (-13.98 ± 1.68%), assessed via the Substance Use Risk Profile Scale at age 14, and uncontrolled eating (-13.98 ± 3.28%), assessed via the Three-Factor-Eating-Questionnaire at age 22, led to significant reductions in mean balanced prediction accuracy upon controlling for them. Thus, sensation-seeking and binge eating could partially explain the prediction of future binge drinking from adolescent brain structure. Our findings suggest that binge drinking and binge eating at age 22 share common neurobiological precursors discovered by the ML model. These neurobiological precursors seem to be associated with sensation-seeking at age 14. Our results facilitate early detection of increased risk for binge drinking and inform future clinical research in trans-diagnostic prevention approaches for adolescent alcohol misuse.

Prescription opioid misuse in relation to addiction susceptibility among women at a Saudi university.

Objectives: The trends of prescription opioid misuse are understudied in Arab populations, let alone among university students. Additionally, little is known about the psychological traits that increase susceptibility for such behaviors in this region. Thus, this study aimed to assess the prevalence of prescription opioid misuse and its association with addiction susceptibility, as measured by the Substance Abuse Risk Profile Scale (SURPS). Methods: We sampled university students from King Saud University's women's campus. Data on prescription opioid misuse, SURPS traits, and demographic characteristics were collected using an electronic self-administered survey. Results: Lifetime prescription opioid misuse was 48.5%, while past-month misuse was 28.9%. On average, SURPS subscale scores for impulsivity (mean = 11.6; SD = 2.8) hopelessness (mean = 12.3; SD = 3.5), sensation seeking (mean = 16.4; SD = 3.8), and anxiety sensitivity (mean = 14.6; SD = 2.6). Anxiety sensitivity composite scores significantly differed between students reporting misuse and those who did not. Moreover, the odds for prescription opioid misuse increased by 7% for every 1 unit increase in anxiety sensitivity (AOR = 1.07; 95% CI = 1.00, 1.14), when controlling for other SURPS measures and student characteristics. Conclusion: The prevalence of prescription opioid misuse in our study is higher than what is reported in global student populations. This may reflect unmonitored availability of controlled substances and unsupervised medical prescriptions. Additionally, high levels of anxiety sensitivity may be driving such misuse. Further surveillance of prescription drug misuse among university students and motivators for such behavior is needed for planning prevention and control interventions.

Anhedonia and impulsivity in college alcohol use: A path analysis.

OBJECTIVE: Alcohol use is a substantial problem among college students and has several negative consequences. The current study examined the associations between anhedonia and alcohol use and related problems via impulsive behavior (e.g., negative urgency, sensation seeking). We parsed anhedonia into four specific facets: consummatory, anticipatory, recreational, and social anhedonia. PARTICIPANTS: Six hundred and forty college students aged 18-25 were included in the final analysis. METHOD: Data were collected via Amazon Mechanical Turk. Self-report inventories assessing for anhedonia, alcohol use, impulsive behavior, and depressed mood were utilized. RESULTS: Recreational consummatory anhedonia was negatively associated with alcohol use and alcohol-related problems through negative urgency. Recreational consummatory anhedonia also had significant negative associations with alcohol consumption via sensation seeking. Further, social anticipatory anhedonia was positively associated with alcohol use and related problems via negative urgency. CONCLUSIONS: This study highlights important associations between anhedonia, impulsivity, and alcohol use and related problems.
