RESUMO
Science knowledge refers to the depth and breadth of facts acquired within the life, social, and earth sciences, and it has implications for both public and personal health. Drawing from cognitive aging theory, we examine whether levels of science knowledge are associated with age, neuropsychological functioning, and personal health literacy. Fifty-two younger and fifty older healthy adults completed our telephone-based study that included a commonly used test of science knowledge, as well as measures of neuropsychological functioning, health literacy, and relevant descriptives (e.g., mood). Adjusting for other demographics and neuropsychological functioning, older adults had significantly lower science knowledge test scores than younger adults. In the full sample, lower science knowledge showed medium-to-large associations with episodic memory, executive functions, and health literacy, independent of years of education. These results suggest that older adults' science knowledge falls slightly below that of their younger counterparts and is independently associated with higher order neuropsychological functions and aspects of personal health, which may have implications for accessing, understanding, and using relevant public health information across the lifespan.
RESUMO
The increase in college enrollment for Hispanic college students warrants increased attention to their health and wellness. Given that a common threat to health and well-being in college students is alcohol use and that Hispanic college students are at elevated risk for alcohol-related problems, it is essential to investigate factors that might lead to heightened alcohol-related problems among this population. The present study is a secondary data analysis of an NIAAA-funded study investigating brief interventions for alcohol use among 583 heavy-drinking college students. Specifically, we examined the relationship between Hispanic student status and alcohol-related problems measured one month later. Additionally, we examined the indirect effects of Hispanic status on alcohol-related problems through drinking motives. Analyses revealed a significant association between Hispanic status and alcohol-related problems at baseline but no association between Hispanic status and problems at 1-month, controlling for baseline problems. An indirect effect of the prospective association between Hispanic student status and alcohol-related problems was evident for only one of the four drinking motives (coping). Our findings suggest that reducing coping motives for drinking among Hispanic college students may reduce alcohol-related problems.
RESUMO
Frequently mentioned anecdotally, hangovers are under-investigated within the scientific study of alcohol, as is the role of physical activity (PA) on hangovers. The well-established positive association between PA and AC (AC) suggests that PA may buffer negative physiological consequences of AC, including hangovers. The present study was therefore conducted in order to determine whether PA influences hangovers. Undergraduates (N=1676) from two large universities in the United States who experienced at least one hangover in the past three months and who engaged in at least 30 min of moderate PA per week were recruited to participate. Participants completed online questionnaires about their AC, PA, and frequency and severity of hangover symptoms. Both between- and within-person associations between AC and hangover were examined, factoring in the potential moderating effects of both moderate and vigorous PA. Small effects were observed for correlations between PA and outcomes assessing AC and hangovers (rs ranged from 0.09 to 0.15). Results also revealed that individuals who consumed more alcohol per month experienced hangovers more frequently and had more severe symptoms. These associations were attenuated among individuals who spent more hours engaging in vigorous but not moderate PA. The current study is the first to show PA influences the experience of hangovers, and we posit this may be a mechanism underlying the positive relationship between PA and AC. Our findings advance the growing literature on alcohol use and PA and may contribute to the development of interventions for alcohol-related problems and alcohol use disorders.

BACKGROUND: Young adult veterans who served after the September 11 attacks on the United States in 2001 (ie, post-9/11) are at heightened risk for experiencing behavioral health distress and disorders including hazardous drinking, posttraumatic stress disorder, and depression. These veterans often face significant barriers to behavioral health treatment, and reaching them through brief mobile phone-based interventions may help reduce drinking and promote treatment engagement. OBJECTIVE: Following a successful pilot study, this randomized controlled trial (RCT) aims to further test the efficacy of a brief (ie, single session) mobile phone-delivered personalized normative feedback intervention enhanced with content to promote treatment engagement. METHODS: We will conduct an RCT with 800 post-9/11 young adult veterans (aged 18 to 40 years) with potentially hazardous drinking and who have not recently received treatment for any behavioral health problems. Participants will be randomly assigned to the personalized intervention or a control condition with resources for seeking care. The personalized normative feedback module in the intervention focuses on the correction of misperceived norms of peer alcohol use and uses empirically informed approaches to increase motivation to address alcohol use and co-occurring behavioral health problems. Past 30-day drinking, alcohol-related consequences, and treatment-seeking behaviors will be assessed at baseline and 3, 6, 9, and 12 months post intervention. Sex, barriers to care, posttraumatic stress disorder, depression, and severity of alcohol use disorder symptoms will be explored as potential moderators of outcomes. RESULTS: We expect recruitment to be completed within 6 months, with data collection taking 12 months for each enrolled participant. Analyses will begin within 3 months of the final data collection point (ie, 12 months follow-up). CONCLUSIONS: This RCT will evaluate the efficacy of a novel intervention for non-treatment-seeking veterans who struggle with hazardous drinking and possible co-occurring behavioral health problems. This intervention has the potential to improve veteran health outcomes and overcome significant barriers to treatment.

BACKGROUND: Drinking identity (the extent to which one links the self with drinking alcohol) is a unique risk factor for college students' hazardous drinking that is not directly targeted by existing interventions. We conducted a study that aimed to decrease drinking identity among college students with hazardous drinking. We adapted a writing task about the future self and tested whether three writing sessions could decrease drinking identity and change drinking. We also investigated whether two additional factors (writing perspective and inclusion of participants' social networks) would enhance task impact. The present study evaluated whether posited proximal cognitive and motivational outcomes (drinking identity, self-efficacy, readiness to change, and drinking intentions) changed immediately after each writing session. METHOD: The study is a randomized clinical trial in which hypotheses and analyses were pre-registered. Participants were 328 college students who met hazardous drinking criteria. The study had a 2 (narrative writing topic: low-risk drinker vs. reduced smartphone use) × 2 (writing perspective: first-person vs. non-first-person) × 2 (social network instruction: instructed to include vs. not) factorial design. Proximal outcomes were drinking identity, self-efficacy, readiness to change, and drinking intentions. The clinical outcome was alcohol consumption. Participants completed three laboratory sessions at weekly intervals that included the writing task and pre- and post-task assessments. RESULTS: Results were largely null, except that readiness to reduce drinking was higher in the low-risk drinker condition and increased over the lab sessions. Time effects indicated that reductions in drinking identity, drinking intentions, and alcohol consumption, and increases in self-efficacy were observed but did not change above and beyond control conditions. CONCLUSIONS: Findings indicate the need to strengthen the writing task and select a more appropriate control task to target proposed proximal outcomes. Future studies might try personalizing the task, evaluating its efficacy with individuals motivated to change their drinking, and using a control task that does not involve imagining a future self.
RESUMO
OBJECTIVE: Among individuals with chronic pain, the rate of hazardous alcohol use is elevated compared with the general population. Yet, hazardous drinkers with chronic pain remain an underserved group. There is a need to develop and test alternative and complementary interventions to reduce hazardous alcohol use among this high-risk segment of the general population. Targeting pain-related anxiety, a candidate mechanism, is one theoretically informed route. METHOD: Our approach followed a staged model (1A/1B) to develop and test a novel personalized feedback intervention (PFI). Phase 1A collected qualitative feedback from participants (N = 9; 77.8% female, mean age = 33.86 years, SD = 8.75) to refine intervention content and evaluate treatment acceptability and feasibility. For Phase 1B, individuals (N = 118; 57.3% male, mean age = 35.24 years, SD = 11.90) participated in a pilot randomized clinical trial for our novel PFI compared with a health information control condition on alcohol use, intention/motivation to reduce drinking, pain-related anxiety, and expectancies for alcohol analgesia/pain coping for hazardous drinkers with chronic pain. RESULTS: Phase 1A results supported the feasibility of using a PFI to target pain-related anxiety. Results from Phase 1B indicated that participants reduced drinking and primary outcomes changed in the expected directions, but there were no differential effects of the intervention. CONCLUSIONS: The current data provide preliminary evidence for the utility of computer-based brief interventions to encourage behavior change. However, further refinement of the intervention to target pain-related anxiety is warranted.

OBJECTIVE: A novel framework for understanding college students' alcohol use is moral injury-psychological distress that stems from events that violate moral beliefs. Considering the predominantly positive associations between moral injury and alcohol use in military samples, this relationship may extend to students. The purpose of this study was to examine the association between potentially morally injurious experiences (PMIEs), alcohol use, and related consequences. Furthermore, we aimed to determine the relative importance of PMIE subtypes on alcohol outcomes. METHOD: Participants included 604 college students (78% female; 38% Caucasian) with a mean age of 21 years (SD = 4.44). We hypothesized that (a) the composite PMIE score would be positively associated with alcohol consumption and consequences and (b) Commission with Agency would have the strongest association with alcohol outcomes, followed by Betrayal, Omission, Commission under Duress, posttraumatic stress (PTS) symptoms, and Witnessing. RESULTS: Analyses revealed that PMIEs were positively associated with alcohol-related consequences but not drinks per week when controlling for PTS symptoms. Moreover, the dominance analysis showed that Commission with Agency had the strongest association with consumption, followed by Betrayal, PTS symptoms, Commission under Duress, Witnessing, and Omission. PTS symptoms had the strongest association with alcohol-related consequences, followed by Commission with Agency, Commission under Duress, Omission, Betrayal, and Witnessing. CONCLUSIONS: These findings help distinguish moral injury constructs from PTS and highlight the importance of Commission with Agency in analyzing alcohol outcomes.

RESUMO
Drinking identity (the extent to which one associates the self with drinking alcohol) is a robust predictor of young adult hazardous drinking (HD; heavy drinking and alcohol-related problems), and decreases in drinking identity have been linked to the decline in HD that often occurs following college graduation. Identifying moderators is key to recognizing who is most at risk for continued HD given a drinking identity vulnerability. Using data from a longitudinal study of graduating college students from the U.S., we evaluated distress (depression, anxiety, stress symptoms) as a potential moderator. Between- and within-person components of drinking identity and distress were evaluated to consider both individual differences and variations within a person across time and changing contexts. Study hypotheses and data analysis plan were preregistered. Graduating college students who met HD criteria (N = 422) completed implicit and explicit drinking identity measures (assessed using reaction time and self-report measures, respectively), distress symptom questionnaires, and self-reported alcohol consumption and problems at four-month intervals for 2.5 years. Results supported moderation at the between-person level for alcohol consumption, with higher levels of implicit drinking identity and distress linked to greater subsequent alcohol consumption. Only between-person main effects for (explicit) identity and distress were linked to more subsequent alcohol-related problems. Though moderation findings were mixed, having a stronger drinking identity and/or greater distress was linked to continued HD risk in this sample. Individuals with these risk factors may benefit from enhanced prevention efforts to help graduates transition out of HD post-college.

College student drinking is prevalent and costly to public and personal health, leading to calls to identify and target novel mechanisms of behavior change. We aimed to manipulate drinking identity (a cognitive risk factor for hazardous drinking) via three sessions of narrative writing about a future self. We tested whether writing could shift drinking identity and would be accompanied by changes in alcohol consumption and problems. Participants were college students meeting hazardous drinking criteria (N = 328; Mage = 20.15; 59% women, 40% men, 1% gender-diverse; 60% white; 23% Asian; 12% multiple races; 2% other racial groups; 8% identified as Hispanic/Latino/a/x). The study had a 2 [narrative writing topic: low-risk drinker vs. reduced smartphone use] × 2 [writing perspective: first person vs. non-first-person] × 2 [social network instruction: instructed to include vs. not] factorial design. Outcomes were drinking identity, drinking refusal self-efficacy, alcohol consumption, alcohol-related problems, and craving. Participants completed three writing sessions and online follow-up assessments at 2, 4, and 12 weeks. The study is a registered clinical trial; hypotheses and analyses were preregistered (https://osf.io/vy2ep/). Contrary to predictions, narrative writing about a future self as a low-risk drinker did not significantly impact outcomes. Null results extended to expected interactions with writing perspective and social network instructions. The narrative writing task did not shift drinking or alcohol-related outcomes. Future experimental work may benefit from greater flexibility in conceptualizing a future self, recruiting individuals interested in behavior change, and more sensitive measures of drinking identity.

Objective: An association exists between perceived belonging and depression among college students. Because a student's sense of belongingness may vary as a function of their social identity, three identities - ethnicity, first-generation college student status, and sex - were investigated as potential moderators of this relationship. Participants: One hundred eighty-seven heavy-drinking college students (63% female; 52% non-Latinx White; M = 20 years of age) were assessed. Methods: Three hierarchical linear regressions were conducted to test whether belonging at baseline predicted depression at six months and whether each identity variable moderated this association. Results: Analyses yielded significant main effects between belonging and depression. Hispanic nor first-generation status interacted with belonging in predicting depression. Sex interacted with belonging where higher belongingness was associated with lower levels of depression only among female students. Conclusion: Mental health providers should consider asking female students about their perceptions of belonging on college campuses to understand their vulnerability to depression.
RESUMO
BACKGROUND: Shame-proneness has been consistently associated with more problematic alcohol outcomes, and guilt-proneness has been associated with fewer. The aim of this study was to determine if the associations of shame-and-guilt-proneness with alcohol outcomes vary as a function of interpersonal sensitivity. METHOD: A longitudinal study examined shame-proneness and guilt-proneness as predictors of alcohol consumption and related problems one month later. This research was conducted at a large public university in the United States. RESULTS: Participants (N=414) were heavy-drinking college students (51% female) with a mean age of 21.76 (SD=2.02) who consumed an average of 12.13 (SD=8.81) standard drinks per week. Shame-proneness, but not guilt-proneness, was directly associated with increased drinking and indirectly associated with increased problems. The indirect effects of shame on problems through drinking were stronger at higher levels of interpersonal sensitivity. CONCLUSIONS: Results suggest that shame-proneness may increase alcohol consumption and subsequent problems among those high in interpersonal sensitivity. Alcohol may be used as a means to withdraw from social threats that are amplified by interpersonal sensitivity.

The COVID-19 pandemic spurred public health measures to reduce viral spread. Concurrently, increases in alcohol consumption and conflict in romantic partnerships were observed. Pre-pandemic research demonstrated a bidirectional association between couples' conflict and drinking. Recent research shows one's drinking motives (proximal predictors of drinking behavior) can influence another person's drinking in close relationships. It is possible that individuals are drinking to cope with distress following romantic conflict. The current study examined 348 cohabitating couples during the first lockdown in the spring of 2020. Our analyses examined coping motives as a mediator between dyadic conflict and drinking behavior using actor-partner interdependence models. Results showed that conflict was associated with greater reports of own drinking in gendered (distinguishable) and nongendered (indistinguishable) analyses through coping motives. Further, in mixed-gender couples, men partners' coping motives predicted less drinking in women, while women partners' coping motives predicted marginally more drinking in men. Partner effects may have been observed due to the increased romantic partner influence during the COVID-19 lockdown. While these results suggest that men's coping motives may be protective against women's drinking, more concerning possibilities are discussed. The importance of considering dyadic influences on drinking is highlighted; clinical and policy implications are identified.

The online proliferation of COVID-19 misinformation led to adverse health and societal consequences. This study investigated possible differences in COVID-19 headline accuracy discernment and online sharing of COVID-19 misinformation between older and younger adults, as well as the role of individual differences in global cognition, health literacy and verbal IQ. Fifty-two younger (18-35 years old) and fifty older adults (age 50 and older) completed a neurocognitive battery, health literacy and numeracy measures, and self-report questionnaires via telephone. Participants also completed a social media headline-sharing experiment (Pennycook et al., Psychological science, 31(7), 770-780, 2020) in which they were presented with true and false COVID-19 headlines about which they indicated: 1) the likelihood that they would share the story on social media; and 2) the factual accuracy of the story. A repeated measures multivariate analysis of variance controlling for gender and race/ethnicity showed no effects of age (p = .099) but a significant interaction between actual COVID-19 headline accuracy and the likelihood of sharing (p < .001), such that accuracy was more strongly related to sharing false headlines (r = -.64) versus true headlines (r = -.43). Moreover, a higher likelihood of sharing false COVID-19 headlines was associated with lower verbal IQ and numeracy skills in older adults (rs = -.51--.40) and with lower verbal IQ, numeracy, and global cognition in younger adults (rs = -.66--.60). Findings indicate that headline accuracy judgements, numeracy, and verbal IQ are important contributors to sharing COVID-19 misinformation in both older and younger adults. Future work might examine the benefits of psychoeducation for improving health and science literacy for COVID-19.

RESUMO
Levels of religiousness vary by geographic location, but studies of the relationship between religiousness and alcohol are often limited to one region. For our participants (N = 1124; 57.5% female), location was significantly associated with both religiousness and alcohol use. Active religiousness was associated with drinking outcomes. The indirect effects of location on drinks per week through active religiousness were significant. At Campus S, subjective religiousness was associated with more drinks per week, whereas active religiousness was associated with fewer drinks per week. Findings indicate active religiousness is especially relevant when exploring drinking, and location is important when exploring religiousness and alcohol use.

Many college students reduce hazardous drinking (HD) following graduation without treatment. Identifying cognitive mechanisms facilitating this "natural" reduction in HD during this transition is crucial. We evaluated drinking identity as a potential mechanism and tested whether within-person changes in one's social network's drinking were linked to within-person changes in drinking identity and subsequent within-person changes in HD. A sample of 422 undergraduates reporting HD was followed from six months before until two years after graduation. Their drinking, drinking identity, and social networks were assessed online. Within-person changes in drinking identity did not mediate the relationship between within-person changes in social network drinking and personal HD, though significant positive between-person associations among all constructs were found. Instead, there was some evidence that within-person changes in drinking identity followed changes in HD, suggesting that drinking identity may function as a marker versus mechanism of "natural" HD reduction during transition out of college.
RESUMO
Perceived norms of drinking prevalence (descriptive norms) and approval (injunctive norms) are among the most robust predictors of college student drinking, but the dynamic fluctuations of these relationships over time are less understood. We examined longitudinal associations of descriptive and injunctive norms on alcohol consumption, disaggregating within-person fluctuations from between-person associations. Participants were 593 heavy drinking college students who completed measures of perceived descriptive and injunctive norms and drinking at baseline, one month, three months, six months, and 12â¯months. Longitudinal multilevel model analyses revealed that, at the between-person level, only descriptive norms predicted drinking. In contrast, both descriptive and injunctive norms at the within-person level predicted weekly drinking. The findings are the first to examine between- and within-person effects of descriptive and injunctive norms simultaneously on drinking and suggest that future college drinking interventions using normative influence would benefit from recognizing and incorporating within-person fluctuations in perceived norms.

OBJECTIVE: Evidence indicates a counterintuitive positive relationship between physical activity and alcohol consumption, suggesting that people who engage in more physical activity consume more alcohol. Impulsivity, which has a well-documented role in alcohol use disorders, has been shown to moderate the between-person physical activity-drinking association among emerging adults. However, only a handful of studies have explored within-person associations of physical activity and drinking and potential moderators of this relationship. The current study evaluated the effects of both subjective and behavioral impulsivity on the within- and between-person association between physical activity and alcohol consumption among college students. METHOD: Undergraduate students (N = 250) between ages 18 and 25 years were asked to report their daily physical activity and drinking over 21 days. Physical activity was also recorded objectively through Pacer, a smartphone app. Subjective impulsivity was assessed using the UPPS-P Impulsive Behavior Scale, and behavioral impulsivity was evaluated using the Balloon Analogue Risk Task. RESULTS: Within- and between-subject physical activity-drinking associations were differentially moderated by behavioral impulsivity and self-reported impulsivity. For instance, behavioral impulsivity moderated the within-person association between drinking and self-reported vigorous physical activity, whereas negative urgency moderated the between-person association between drinking and objective physical activity. CONCLUSIONS: Impulsivity, whether measured subjectively or behaviorally, significantly moderates the physical activity-alcohol consumption association. Importantly, this effect operates differently when predicting variation in behavior within individuals as compared with predicting differences in behavior between individuals.

U.S. young adults face the largest student loan burden in history, rising income inequality, and economic uncertainty. Personal debt and other financial stressors have been associated with problematic drinking and mental health symptoms. In this paper, we investigated whether student loan debt was more strongly linked to problem drinking and mental health symptoms among those in lower positions of socioeconomic status (SES) and those who perceived greater [in]stability in their SES (SES-instability). Using data from a larger study of college graduates, we investigated SES, SES-instability, student debt, and their 2-way interactions on problematic drinking and mental health symptoms. College graduates (N = 331), who were two years post-graduation, completed measures assessing student debt, perceived SES, SES-instability, problematic drinking, and mental health symptoms (depression, anxiety, and stress). The hypotheses and data analysis plan were registered prior to conducting analyses. The expected unique, positive associations of SES-instability with problematic drinking and mental health symptoms were supported. SES was uniquely linked with problematic drinking only and in the opposite direction as predicted. Student debt was uniquely and positively linked to stress only. The expected interactions were largely supported for SES-instability and student debt-i.e., the associations of student debt with problematic drinking, anxiety, and stress were stronger (more positive) for those with greater SES-instability. The expected interactions for SES and student debt were null. Though data are cross-sectional and come from an educationally-privileged group, study findings provide preliminary evidence of links between young adult student loan debt, greater SES-instability, and their drinking/mental health.

OBJECTIVE: Single-component personalized normative feedback (PNF) interventions and multicomponent personalized feedback interventions (PFI) have been shown to reduce alcohol consumption among college students. The present study compared the efficacy of PNF interventions targeting descriptive norms alone (descriptive PNF), injunctive norms alone (injunctive PNF), or their combination (combined PNF), against a multicomponent PFI and an attention control condition. METHOD: Undergraduates (N = 1,137) across two universities who reported a minimum of one past-month episode of heavy episodic drinking (i.e., 4 +/5 + drinks on a single occasion for females/males) completed assessments at baseline and 3, 6, and 12 months postintervention. RESULTS: Relative to the attention control, participants in each of the four intervention conditions showed greater reductions in perceived descriptive/injunctive norms, total drinks per week, and alcohol-related consequences. Peak estimated blood alcohol concentration was also reduced in the injunctive PNF, combined PNF, and multicomponent PFI conditions, with the latter two conditions showing an advantage for duration of effects. The multicomponent PFI condition also evidenced greater reductions than the injunctive PNF in descriptive norms at 3-month and injunctive norms at 6- and 12-month follow-ups. No other group comparisons on any outcome were significant. CONCLUSIONS: Each intervention has merit for use in college student harm reduction efforts. Single-component or combined PNF could be considered a potential starting point, as PNF is less burdensome than a multicomponent PFI when considering ease and length of delivery. Results can inform optimization of norms-based interventions and guide recommendations on efficacious components for reducing alcohol use and harms on college campuses.

Indirect measures have been used to assess the strength of automatically activated, alcohol-related associations and their relation to hazardous drinking. However, little is known about the longitudinal contributions of between-person and within-person components of implicit alcohol associations (IAAs) to college students' hazardous drinking over time. This study examined how within- and between-person variability in three measures of IAA (drinking identity, alcohol approach, and alcohol excite) are related to hazardous drinking while controlling for their explicit, self-report counterparts. First- and second-year U.S. college students (N = 506; 57% female) completed web-based assessments once every 3 months up to eight assessments, which included IAA measures (Implicit Association Tests), explicit counterparts of the IAAs, and self-reported hazardous drinking (alcohol consumption, problems, and risk of alcohol use disorder). Bayesian generalized multilevel models were used to examine between- and within-person associations among IAA, their explicit counterparts, and hazardous drinking. Results showed that between persons, mean levels of all three IAAs were positively associated with hazardous drinking over time. Once their explicit, self-report counterparts were included, however, only drinking identity IAA remained significant. Within persons, increases in drinking identity IAA were associated with increases in subsequent hazardous drinking risk, even after controlling for its explicit counterpart. These results suggest the importance of disentangling and simultaneously investigating between- and within-person processes in IAAs. Although the between-person component of IAAs may play a larger role in the prediction of hazardous drinking, examining the within-person component of IAA, at least for drinking identity, also appears to be important.
