Are accuracy discernment and sharing of COVID-19 misinformation associated with older age and lower neurocognitive functioning?

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.

Incorporating Social Networks and Event-Specific Information in a Personalized Feedback Intervention to Reduce Drinking Among Young Adults.

AIMS: To correct risky alcohol use among young adults, current personalized feedback interventions (PFIs) use social influence information related to distal referent groups. Although current PFIs have been effective, little consideration has been given to strategies applying more concrete sources of social influence, namely the influence of specific people within one's social network during actual drinking contexts. The current study evaluated a novel PFI, providing feedback regarding the presence or absence of particular individuals within a participant's close network along with the number of drinks consumed and consequences experienced during several specific drinking occasions. METHODS: TurkPrime users (N = 338) identified five close others with whom they sometimes drank. They also provided details about their five most recent drinking occasions and noted which of their network members were present. Participants were then randomized to receive or not receive feedback consisting of a list of drinking events, negative consequences and who was present. RESULTS: Feedback participants intended to consume fewer drinks over the next month relative to control (b = -0.25, P = 0.001). Analyses were inconclusive as to whether this effect was stronger for those who received more feedback (b = -0.01, P = 0.857). CONCLUSIONS: Results provide preliminary support for the efficacy of a novel social influence-based intervention, which provides personalized feedback indicating social contexts that are more and less likely to lead to negative alcohol-related experiences.

Opportunities for reducing college drinking: The roles of drinking attitudes and blackout experience.

BACKGROUND: As many as 35% of college students report having been drunk in the past month, and greater alcohol use and alcohol-related problems are associated with a positive attitude toward heavy drinking. One serious consequence of heavy drinking is alcohol-induced blackout. When they occur, alcohol-induced blackouts present a unique opportunity to increase motivation to change drinking. However, it is unclear under what conditions an alcohol-related heavy drinking attitude and experiencing a blackout represent an opportunity to change and how experiencing a blackout(s) influences an individual's motivation to reduce drinking and actual behavior. METHODS: This study tested the interplay between one's positive attitude toward heavy drinking and experiencing a blackout in the past year in predicting motivation to reduce drinking (Study 1) and its impact on drinking over time (Study 2). Data were derived from complementary datasets collected at two universities (Study 1 n = 703, mean age = 20.63 years, 44% male, 52% White; Study 2 n = 568, mean age = 19.18 years, 72% male, 84% White). Drinking behavior was measured using a modified Daily Drinking Questionnaire, the Drinking Norms Rating Form, the Alcohol Use Disorders Identification Test (AUDIT), and estimated peak blood alcohol concentration (BAC). Regression analyses were conducted to determine whether a blackout would moderate the association between attitude and motivation to reduce drinking (Study 1) and drinking over time (Study 2). RESULTS: Results revealed a significant interaction between attitude and blackout, such that individuals who experience a blackout (vs. those who do not) and positively evaluate heavy drinking evidenced lower motivation to reduce drinking (Study 1) and higher levels of estimated peak BAC (Study 2). CONCLUSIONS: Drinkers with a negative attitude toward heavy drinking who have experienced a blackout have the strongest motivation to reduce drinking and the greatest reductions in peak drinking behavior over time. These effects are over and above that related to the level of alcohol consumed. For young adults who do not positively endorse heavy drinking, blackouts may present a "moment of opportunity" for intervention.

The relationship between sex-related alcohol expectancies and hazardous drinking among persons with HIV disease.

Hazardous drinking is a clinically significant problem among persons with HIV (PWH) disease, and is associated with a number of poor outcomes. Hazardous drinking among PWH is associated with risky substance use and sexual behavior, but little work has examined factors that may be associated with greater hazardous drinking and subsequent risky sexual behaviors among PWH. Research among the general population suggests that sex-related alcohol expectancies, defined as drinking to enhance sexual experience, increase sexual risk-taking, and disinhibition of sexual behavior, are associated with greater hazardous alcohol use and risky sexual behavior, but these relations have not been explored among PWH. Therefore, the current study examined the associations of sex-related alcohol expectancies with hazardous alcohol consumption, dependence, and problems among 146 PWH (Mage = 50.99, SD = 9.41) \ enrolled in a clinical trial examining a personalized feedback intervention to reduce hazardous drinking in primary HIV care. Results showed that only sexual disinhibition-related alcohol expectancies were significantly associated with the criterion variables, such that greater drinking alcohol for sexual disinhibition was associated with greater hazardous drinking behaviors. These results sit on the backdrop of a larger literature documenting the links between disinhibition and hazardous alcohol use and provide explanatory specificity to PWH who are hazardous drinkers.

Double Vision on Social Media: How Self-Generated Alcohol-Related Content Posts Moderate the Link between Viewing Others' Posts and Drinking.

A robust finding is the positive association between self-generated alcohol-related content (SG-ARC) on social media (SM) and drinking among emerging adults; however, the reasons for this relationship are still unclear. A factor that has yet to be explored in combination with SG-ARC is how viewing others' alcohol-related content (ARC) may be impacting young adults' drinking. This cross-sectional study conducted across two universities asked students (N = 780; M = 20.80 years old; SD = 2.29; 67.82% female) to self-report how many SG-ARC posts they posted, to estimate how much they saw others' ARC, and how much they drank weekly. SG-ARC was then evaluated as a moderator of the association between viewing others' ARC and drinking. A negative binomial regression model with robust sandwich estimators was employed. Results revealed that both SG-ARC and viewing others' ARC were positively associated with drinking. A significant two-way interaction between SG-ARC and others' ARC emerged such that viewing others' posts appeared to exert an influence on drinking, particularly for students who did not post as many SG-ARC posts. These findings provide evidence that seeing others' ARC may be socially influencing students to drink, especially if they do not post as much SG-ARC themselves, by altering their internalized drinking norms.

A Marijuana Consequences Checklist for Young Adults with Implications for Brief Motivational Intervention Research.

Measures assessing marijuana-related consequences or problems experienced by young adults have typically been adapted from measures assessing alcohol consequences. These measures may not fully reflect the specific unwanted or perceived "not so good" effects of marijuana that are experienced by young adults. Thus, using these measures may present a gap, which needs to be addressed, given that reports of consequences are often utilized in brief motivational personalized feedback interventions. Data from three different studies of young adults were used to (1) examine self-reported "not so good" effects or consequences of marijuana use among frequent marijuana-using college students (Study 1), (2) create a new version of a marijuana consequences list and compare it to an existing marijuana consequences measure (Study 2), and (3) assess convergent and divergent validity between a finalized Marijuana Consequences Checklist (MCC, 26-items) and marijuana use and risk for cannabis use disorder (Study 3). The most frequently endorsed self-reported effects of marijuana included the impact on eating (the "munchies"), dry mouth, trouble concentrating, and acting foolish or goofy. Higher scores on the MCC were associated with more frequent use and a higher probability of meeting criteria for cannabis use disorder. The MCC represents a range of negative consequences of marijuana use derived from frequent users' own accounts and includes consequences not assessed by other measures. The MCC captures marijuana-specific negative consequences relevant for young adults, which can be incorporated in brief motivational personalized feedback interventions.

Personalized Feedback for Smoking and Anxiety Sensitivity: A Randomized Controlled Trial.

BACKGROUND: Cigarette smoking is the leading preventable cause of death and disability globally. Most smokers want to quit, and most make a serious quit attempt each year. Nevertheless, more than 95% of cessation attempters relapse within six months. Thus, alternative interventions are needed to combat this major public health concern. Objective: The current study was conducted to develop and test a smoking treatment among 95 (63.2% male; Mage = 46.20 years, SD = 10.90) adult daily cigarette smokers that targets a known risk factor for smoking maintenance and relapse: anxiety sensitivity (AS). Methods: The current study employed a randomized controlled trial design to test an integrated, brief, computer-delivered smoking and AS intervention among current, daily smokers. Participants completed four appointments: (a) phone-screener; (b) baseline (pre-intervention assessment, intervention [personalized feedback intervention (PFI) versus smoking information control], and post-intervention assessment); (c) 2-week follow-up; and (d) 4-week follow-up. Results: Participants indicated highly positive evaluations of both the PFI and control intervention. Between the baseline and 2-week follow-up, 44.2% [PFI: 46.9% (n = 23); control: 41.3% (n = 19)] of participants reported a quit attempt. At the 4-week follow-up, 49.5% [PFI: 57.1% (n = 28); control: 41.3% (n = 19)] of participants reported a quit attempt since their previous laboratory session. Conclusion: Within the context of an intervention development approach, the present investigation provides descriptive data on the feasibility, acceptability, and initial efficacy of a single-session, computer-delivered, AS/smoking PFI.

Self in the Service: Self-Identification Moderates the Association between Perceived Drinking Norms and Own Drinking among Veterans.

PURPOSE: Drinking is common among young adult veterans. Previous research has established that veterans' drinking is more strongly associated with veteran versus civilian drinking norms. The present research extends these findings by examining the influence of self-identification both with other veterans and with civilians as moderators of the association between perceived norms and drinking. METHODS: Veterans aged 18-34 (N = 1015; 88.7% male; M = 28.23, SD = 3.44) were recruited via Facebook to participate. Measures included same-gender veterans/same-gender civilians self-identification, same-gender veterans/same gender-civilians perceived drinking norms, and own drinking. RESULTS: Pairwise comparisons revealed both male and female veterans identified more with other veterans than civilians and perceived drinking to be more prevalent among other veterans than civilians. However, males overestimated male veteran drinking norms to a greater degree than male civilian norms whereas the opposite was true for females. Negative binomial analysis examining a three-way interaction between veteran identification, civilian identification, and civilian norms revealed civilian drinking norms were positively associated with drinking, particularly for veterans who strongly identified with both veterans and civilians. Conversely, civilian drinking norms were also found to be negatively associated with drinking, particularly for those who did not identify strongly with civilians but identified strongly with veterans. IMPLICATIONS: This study represented a preliminary step for understanding how identity plays a role in terms of veterans' drinking. Given that veterans drank at differing levels of identification, it may be important to consider identities that are most salient when designing interventions targeting individual veterans.

Growth Mindsets of Alcoholism Buffer Against Deleterious Effects of Drinking Identity on Problem Drinking Over Time.

BACKGROUND: Explicit (self-report) and implicit (indirect) measures of identification with drinking alcohol-drinking identity-are associated with drinking outcomes cross-sectionally and longitudinally. A key next step is to identify moderators. The current study evaluated a promising moderator: mindsets of alcoholism. Believing people can change (growth mindset) is associated with adaptive outcomes in domains such as mental health, but research is scant regarding mindsets related to problematic drinking. We evaluated whether individuals' alcoholism mindsets moderated the drinking identity to drinking relation as part of a larger, longitudinal web-based study of heavy drinkers. METHODS: A total of 422 US college graduates (59% women) who were heavy drinkers completed measures assessing drinking identity, mindsets, and drinking outcomes (consumption, problems, and risk of alcohol use disorder). Drinking outcomes were assessed at 2 subsequent assessments occurring 4 and 8 months after the initial assessment. RESULTS: Drinking identity was positively associated with drinking outcomes, and drinking outcomes reduced following college graduation. Alcoholism mindsets were significantly and negatively correlated with all drinking outcomes. Mindsets were only conditionally associated with drinking behaviors over time in models that evaluated mindsets, drinking identity measures, and their interaction. Mindsets moderated the relationship between drinking identity and changes in drinking behaviors, but the relation was specific to explicit drinking identity and consumption. Among participants with stronger drinking identity, those who had stronger (vs. weaker) growth mindsets reported reduction in consumption over time. CONCLUSIONS: Growth mindsets of alcoholism appear adaptive for college graduate heavy drinkers with a stronger drinking identity. Mindsets are amenable to interventions; targeting them may be useful in heavy-drinking college graduates.

Incorporating Writing into a Personalized Normative Feedback Intervention to Reduce Problem Drinking Among College Students.

BACKGROUND: Personalized normative feedback (PNF) interventions have repeatedly been found to reduce drinking among undergraduates. However, effects tend to be small, potentially due to inattention to and inadequate processing of the information. Adding a writing component to PNF interventions may allow for greater cognitive processing of the feedback, thereby boosting intervention efficacy. Additionally, expressive writing (EW) has been shown to reduce drinking intentions; however, studies have not examined whether it can reduce drinking behavior. The present experiment evaluated whether including a writing task would improve the efficacy of PNF and whether EW alone can be used to reduce drinking and alcohol-related problems. METHODS: Heavy drinking undergraduates (N = 250) were randomized to receive either: (i) PNF about their alcohol use; (ii) EW about a negative, heavy drinking occasion; (iii) PNFplus writing about the norms feedback; or (iv) attention control feedback about their technology use in an online brief intervention. Participants (N = 169) then completed a 1-month follow-up survey about their past month alcohol use and alcohol-related problems online. RESULTS: PNFplus writing reduced alcohol-related problems compared to all other conditions. No significant reductions were found for EW. Both PNF and PNFplus writing reduced perceived norms and perceived norms mediated intervention effects for both feedback conditions. CONCLUSIONS: The current findings suggest that adding a writing component to traditional norms-based feedback approaches might be an efficacious strategy, particularly for reducing alcohol-related consequences.

Health-Related Quality of Life Among Homeless Smokers: Risk and Protective Factors of Latent Class Membership.

Health-related quality of life (HRQoL) is a multidimensional assessment of well-being and health status. Most work in this area assumes that HRQoL is a homogenous construct; however, it is possible HRQoL subgroups may exist. The purpose of the study was to characterize common classes of HRQoL among adult, homeless smokers, a particularly vulnerable group of the larger population, and to evaluate risk and protective factors of HRQoL class membership. Homeless smokers (N = 456; 65.1% male; Mage = 43.19 years [SD = 11.77]) completed self-report measures of sociodemographics, smoking characteristics, anxiety sensitivity, stress, social support, and the Center for Disease Control (CDC) four-item HRQoL measure. A latent class analysis was conducted for HRQoL. Multinomial regression models were used to simultaneously test correlates of class membership. A three-class solution, consisting of poor HRQoL, moderate HRQoL, and excellent HRQoL, demonstrated superior fit. Correlates of class membership included sex, age, lifetime months of being homeless, smoking characteristics, anxiety sensitivity, stress, and social support. The current findings provide novel evidence for three distinct classes of HRQoL among homeless smokers. Results suggest that older smokers with greater emotional distress, as evidenced by greater anxiety sensitivity, greater stress, and less social support, may be particularly vulnerable to poorer HRQoL.

Tailgating Protective Behavioral Strategies Mediate the Effects of Positive Alcohol Outcome Expectancies on Game Day Drinking.

Although a growing body of evidence suggests protective behavioral strategies are associated with lower alcohol use among college students, we know little about what contributes to students' decisions to use these strategies. Alcohol outcome expectancies have been associated with alcohol use among college students, and may contribute to their decisions to use protective behavioral strategies while drinking in contexts associated with an elevated risk for heavy alcohol use. University football game tailgating is one high-risk context that has received limited empirical attention with respect to identifying risk and protective factors for use. We sought to determine whether expectancy effects on tailgating drinking may be attributable to the approach or avoidance of protective strategies in this context. We expected college students who perceive greater positive expectancies to report engaging in more protective strategies on game day, whereas we hypothesized greater negative expectancies would be associated with less use of protective strategies. College students (N = 231) reported outcome expectancies online within 7 days of tailgating and quantity of alcoholic drinks consumed while tailgating, as well as whether they used limiting consumption (i.e., counting drinks, alternating drinking water and alcohol) and harm reduction (HR; i.e., sober transportation) strategies 48 h after tailgating. Results indicated higher positive expectancies were associated with greater use of HR strategies. Positive expectancies were indirectly positively related to greater game day tailgating drinking and negatively to odds of abstaining through the use of protective strategies, and unique indirect effects were observed for HR strategies. These findings highlight important individual differences that contribute to the use of protective behaviors, and suggest that expectancy-challenge interventions may be tailored to address unsafe drinking practices and promote college student health.

Evaluating Within-Person Change in Implicit Measures of Alcohol Associations: Increases in Alcohol Associations Predict Increases in Drinking Risk and Vice Versa.

AIMS: Implicit measures of alcohol associations (i.e. measures designed to assess associations that are fast/reflexive/impulsive) have received substantial research attention. Alcohol associations related to the self (drinking identity), the effects of alcohol (alcohol excite) and appetitive inclinations (alcohol approach) have been found to predict drinking cross-sectionally and over time. A critical next step in this line of research and the goal of this study is to evaluate whether increases in the strength of these associations predict increases in drinking and vice versa. These hypotheses were tested in a sample of first- and second-year US university students: a sample selected because this time period is associated with initiation and escalation of drinking, peak levels of alcohol consumption and severe alcohol-related negative consequences. SHORT SUMMARY: This study's purpose was to evaluate whether increases in the strength of alcohol associations with the self (drinking identity), excitement (alcohol excite) and approach (alcohol approach) as assessed by implicit measures predicted subsequent increases in drinking risk and vice versa using a longitudinal, university student sample. Results were consistent with hypotheses. METHODS: A sample of 506 students' (57% women) alcohol associations and alcohol consumption were assessed every 3 months over a 2-year period. Participants' consumption was converted to risk categories based on NIAAA's criteria: non-drinkers, low-risk drinkers and high-risk drinkers. A series of cross-lagged panel models tested whether changes in alcohol associations predicted subsequent change in drinking risk (and vice versa). RESULTS: Across all three measures of alcohol associations, increases in the strength of alcohol associations were associated with subsequent increases in drinking risk and vice versa. CONCLUSION: Results from this study indicate bi-directional relationships between increases in alcohol associations (drinking identity, alcohol excite and alcohol approach) and subsequent increases in drinking risk. Intervention and prevention efforts may benefit from targeting these associations.

Caregiver alcohol use and mental health among children orphaned by HIV/AIDS in South Africa.

Research in the developed world suggests that parental alcohol use negatively impacts child mental health. However, little research has examined these relations among children in the developing world and no studies to date have done so in the context of AIDS-orphanhood. Therefore, the present study tested the interactive effect of AIDS-orphan status with caregiver alcohol use on child mental health. The sample included 742 children (51.2% female; Mage = 9.18; age range: 7-11 years; 29.8 AIDS-orphans; 36.8% orphaned by causes other than AIDS; 33.4% non-orphaned) recruited from Mangaung in the Free State Province of South Africa. Child mental health was assessed via child self-report, caregiver, and teacher reports; and caregiver alcohol use via self-report. Path analyses, via structural equation modeling, revealed significant direct effects for AIDS-orphan status on caregiver-reported child mental health; and for caregiver alcohol-use problems on teacher-reported child mental health. However, the interaction effect of AIDS-orphan status with caregiver alcohol use did not reach significance on all three reports of child mental health problems. These results suggest that orphan status and caregiver alcohol use may independently relate to mental health problems in children and that the effects of both should be considered in the context of the mental health needs of children in AIDS-affected countries.

Prototype Willingness Model Drinking Cognitions Mediate Personalized Normative Feedback Efficacy.

Personalized normative feedback (PNF) interventions have been shown to be efficacious at reducing college student drinking. Because descriptive norms have been shown to mediate PNF efficacy, the current study focused on examining additional prototype willingness model social reaction cognitions, namely, prototypes and willingness, as mediators of intervention efficacy. We expected the PNF interventions to be associated with increased prototype favorability of students who do not drink, which would in turn be associated with decreased willingness to drink and subsequently, less drinking. The current study included 622 college students (53.2% women; 62% Caucasian) who reported one or more heavy drinking episodes in the past month and completed baseline and three-month follow-up assessments. As posited by the framework of the prototype willingness model, sequential mediation analyses were conducted to evaluate increases in abstainer prototype favorability on willingness on drinking, and subsequently willingness to drink on drinking behavior. Mediation results revealed significant indirect effects of PNF on three-month drinking through three-month prototypes and willingness, indicating that the social reaction pathway of the prototype willingness model was supported. Findings have important implications for PNF interventions aiming to reduce high-risk drinking among college students. Study findings suggest that we should consider looking at additional socially-based mediators of PNF efficacy in addition to perceived descriptive norms.

A review of implicit and explicit substance self-concept as a predictor of alcohol and tobacco use and misuse.

BACKGROUND: This paper provides an overview of the self-concept as it relates to substance use. Self-concept has a long history in psychological theory and research; however, substance self-concept (e.g., viewing one's self as a drinker or smoker) is an understudied area of research with the potential to expand existing conceptualizations of substance use, addiction, and prevention and treatment efforts, and should receive greater research attention. OBJECTIVES: First, we review and provide a theoretical framework of substance self-concept that draws from dual process models and distinguishes between implicit and explicit self-concept. Next, we summarize key findings related to substance use in the extant literature, focusing on alcohol and tobacco (smoking). RESULTS: Across both substances, there is converging evidence that substance self-concept is associated with substance use outcomes, including quantity and frequency of use and problems associated with use, and that change in substance self-concept is associated with recovery from substance misuse. Recommendations for the substance self-concept research agenda include routine assessment of substance self-concept, expanded use of implicit measures, investigation of moderators of substance self-concept, and targeting substance self-concept directly in prevention and intervention efforts. CONCLUSION: Ultimately, we suggest that substance self-concept is a promising, but understudied, construct. Greater research attention to substance self-concept could clarify its potential as an important risk factor for hazardous use and addiction as well as its utility as a prevention and treatment target.

Comorbidity of Alcohol and Gambling Problems in Emerging Adults: A Bifactor Model Conceptualization.

Addictive disorders, such as pathological gambling and alcohol use disorders, frequently co-occur at greater than chance levels. Substantive questions stem from this comorbidity regarding the extent to which shared variance between gambling and alcohol use reflects a psychological core of addictive tendencies, and whether this differs as a function of gender. The aims of this study were to differentiate both common and unique variance in alcohol and gambling problems in a bifactor model, examine measurement invariance of this model by gender, and identify substantive correlates of the final bifactor model. Undergraduates (N = 4475) from a large northwestern university completed an online screening questionnaire which included demographics, quantity of money lost and won when gambling, the South Oaks Gambling Screen, the AUDIT, gambling motives, drinking motives, personality, and the Brief Symptom Inventory. Results suggest that the bifactor model fit the data well in the full sample. Although the data suggest configural invariance across gender, factor loadings could not be constrained to be equal between men and women. As such, general and specific factors were examined separately by gender with a more intensive subsample of females and males (n = 264). Correlations with motivational tendencies, personality traits, and mental health symptoms indicated support for the validity of the bifactor model, as well as gender-specific patterns of association. Results suggest informative distinctions between shared and unique attributes related to problematic drinking and gambling.

Injunctive Norms and Alcohol Consumption: A Revised Conceptualization.

BACKGROUND: Injunctive norms have been found to be important predictors of behaviors in many disciplines with the exception of alcohol research. This exception is likely due to a misconceptualization of injunctive norms for alcohol consumption. To address this, we outline and test a new conceptualization of injunctive norms and personal approval for alcohol consumption. Traditionally, injunctive norms have been assessed using Likert scale ratings of approval perceptions, whereas descriptive norms and individual behaviors are typically measured with behavioral estimates (i.e., number of drinks consumed per week, frequency of drinking). This makes comparisons between these constructs difficult because they are not similar conceptualizations of drinking behaviors. The present research evaluated a new representation of injunctive norms with anchors comparable to descriptive norms measures. METHODS: A study and a replication were conducted including 2,559 and 1,189 undergraduate students from 3 different universities. Participants reported on their alcohol-related consumption behaviors, personal approval of drinking, and descriptive and injunctive norms. Personal approval and injunctive norms were measured using both traditional measures and a new drink-based measure. RESULTS: Results from both studies indicated that drink-based injunctive norms were uniquely and positively associated with drinking, whereas traditionally assessed injunctive norms were negatively associated with drinking. Analyses also revealed significant unique associations between drink-based injunctive norms and personal approval when controlling for descriptive norms. CONCLUSIONS: These findings provide support for a modified conceptualization of personal approval and injunctive norms related to alcohol consumption and, importantly, offer an explanation and practical solution for the small and inconsistent findings related to injunctive norms and drinking in past studies.

The sequential pathway between trauma-related symptom severity and cognitive-based smoking processes through perceived stress and negative affect reduction expectancies among trauma exposed smokers.

BACKGROUND AND OBJECTIVES: Smoking rates are markedly higher among trauma-exposed individuals relative to non-trauma-exposed individuals. Extant work suggests that both perceived stress and negative affect reduction smoking expectancies are independent mechanisms that link trauma-related symptoms and smoking. Yet, no work has examined perceived stress and negative affect reduction smoking expectancies as potential explanatory variables for the relation between trauma-related symptom severity and smoking in a sequential pathway model. Methods The present study utilized a sample of treatment-seeking, trauma-exposed smokers (n = 363; 49.0% female) to examine perceived stress and negative affect reduction expectancies for smoking as potential sequential explanatory variables linking trauma-related symptom severity and nicotine dependence, perceived barriers to smoking cessation, and severity of withdrawal-related problems and symptoms during past quit attempts. RESULTS: As hypothesized, perceived stress and negative affect reduction expectancies had a significant sequential indirect effect on trauma-related symptom severity and criterion variables. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Findings further elucidate the complex pathways through which trauma-related symptoms contribute to smoking behavior and cognitions, and highlight the importance of addressing perceived stress and negative affect reduction expectancies in smoking cessation programs among trauma-exposed individuals.
