In what settings and social contexts do young adults vape or smoke cannabis? Findings from a web-based diary pilot study.

BACKGROUND: Vaping is an increasingly common mode of cannabis use among young adults. Despite potential to inform targeted prevention, settings and social contexts where young adults vape and/or smoke cannabis have rarely been investigated. We addressed this question in a diverse young adult sample. METHODS: Data were collected weekly in a web-based daily diary format for six weeks. The analytic sample consisted of the 108 participants (of the 119 enrolled) who used cannabis during the assessment period (mean age = 22.06; 23.78% college students; 65.74% female; 5.56% Asian, 22.22% Black, 16.67% Latinx, 2.78% Multi-racial or Other and 52.77% White). Cannabis use was queried separately for vaping and smoking; respondents reported all settings (14 options) and social contexts (7 options) where they used. RESULTS: For both vaping and smoking cannabis, the most common settings were home (vaping: 56.97%, smoking: 68.72% [significantly lower for vaping]), friend's home (vaping: 22.49%, smoking: 21.49%), and car (vaping: 18.80%, smoking: 12.99%). The most common social contexts were with friends (vaping: 55.96%, smoking: 50.61%), with significant other (vaping: 25.19%, smoking: 28.53%), and alone (vaping: 25.92%, smoking: 22.62%). Compared to non-students, college students reported vaping on a significantly higher proportion (27.88% vs. 16.50%) of cannabis use days. CONCLUSIONS: Very similar patterns in settings and social contexts were observed for vaping as smoking and in prevalence of vaping and smoking cannabis across demographic groups. The few notable exceptions have implications for vaping related public health measures: targeting reducing vaping outside the home, particularly in cars, and implementing prevention programming on college campuses.

Casino Gambling in Adolescents: Gambling-Related Attitudes and Behaviors and Health and Functioning Relationships.

Recreational and problem gambling have been linked with adverse health and functioning outcomes among adolescents. Youth may gamble and engage in other risk-taking behaviors in casinos. There are limited data available regarding casino gambling in high-school students, and factors linked to adolescent gambling in casinos have yet to be systematically investigated. To address this gap, we analyzed cross-sectional data from 2010 Connecticut high-school students with chi-square tests and logistic regression models to examine casino gambling in relation to at-risk/problem gambling (ARPG) with respect to sociodemographic characteristics, gambling perceptions & attitudes, health/functioning measures and gambling behaviors. Approximately 11 % of adolescents acknowledged gambling in casinos. ARPG was more frequent and gambling perceptions were more permissive among adolescents endorsing casino gambling. Stronger relationships between ARPG and heavy alcohol and drug use and weaker relationships between ARPG and engagement in extracurricular activities, gambling with friends, gambling with strangers and gambling for financial reasons were observed among adolescents endorsing casino gambling. In conclusion, gambling in casinos was endorsed by a sizable minority of adolescents who gamble, and prevention efforts should consider targeting permissive attitudes towards gambling, adolescent drinking and participation in extracurricular activities when addressing underage casino gambling.

Cannabis use, problem-gambling severity, and psychiatric disorders: Data from the National Epidemiological Survey on Alcohol and Related Conditions.

Cannabis use and related disorders are common in adults and frequently co-occur with subsyndromal and pathological gambling. However, understanding how cannabis use may moderate relationships between problem-gambling severity and psychiatric disorders remains poorly understood. Data from the National Epidemiological Survey on Alcohol and Related Conditions (N = 43,093 adults) were examined to investigate how cannabis use moderated associations between problem-gambling severity (with gambling groups based on the 10 Diagnostic and Statistical Manual [DSM-IV] inclusionary criteria for pathological gambling) and Axis I and Axis II psychiatric disorders. Problem-gambling severity groups included low frequency/nongambling, low-risk gambling, at-risk gambling, and problem/pathological gambling (PPG). Among both the group with lifetime cannabis use and that which never used cannabis, greater problem-gambling severity was associated with more psychopathology across mood, anxiety, substance-use and Axis II disorders. Significant Cannabis Use × Problem-Gambling Severity Group interactions were observed between PPG and major depression (OR = 0.35, 95% CI = [0.14-0.85]), cluster A personality disorders (OR = 0.37, 95% CI = [0.16-0.86])-especially paranoid personality disorder (OR = 0.34, 95% CI = [0.14-0.81])-and cluster B personality disorders (OR = 0.36, 95% CI = [0.18-0.75])-especially antisocial personality disorder (OR = 0.25, 95% CI = [0.11-0.60]). In all cases, associations between problem-gambling severity and psychopathologies were weaker among the lifetime-cannabis-using group as compared to the never-using group. Cannabis use moderates the relationships between problem-gambling severity and psychiatric disorders, with cannabis use appearing to account for some of the variance in the associations between greater problem-gambling severity and specific forms of psychopathology.

The effect of a community health worker intervention on public satisfaction: evidence from an unregistered outcome in a cluster-randomized controlled trial in Dar es Salaam, Tanzania.

BACKGROUND: There is a dearth of evidence on the causal effects of different care delivery approaches on health system satisfaction. A better understanding of public satisfaction with the health system is particularly important within the context of task shifting to community health workers (CHWs). This paper determines the effects of a CHW program focused on maternal health services on public satisfaction with the health system among women who are pregnant or have recently delivered. METHODS: From January 2013 to April 2014, we carried out a cluster-randomized controlled health system implementation trial of a CHW program. Sixty wards in Dar es Salaam, Tanzania, were randomly allocated to either a maternal health CHW program (36 wards) or the standard of care (24 wards). From May to August 2014, we interviewed a random sample of women who were either currently pregnant or had recently delivered a child. We used five-level Likert scales to assess women's satisfaction with the CHW program and with the public-sector health system in Dar es Salaam. RESULTS: In total, 2329 women participated in the survey (response rate 90.2%). Households in intervention areas were 2.3 times as likely as households in control areas to have ever received a CHW visit (95% CI 1.8, 3.0). The intervention led to a 16-percentage-point increase in women reporting they were satisfied or very satisfied with the CHW program (95% CI 3, 30) and a 15-percentage-point increase in satisfaction with the public-sector health system (95% CI 3, 27). CONCLUSIONS: A CHW program for maternal and child health in Tanzania achieved better public satisfaction than the standard CHW program. Policy-makers and implementers who are involved in designing and organizing CHW programs should consider the potential positive impact of the program on public satisfaction.

Perceived injunctive norms and cannabis-related problems: The interactive influence of parental injunctive norms and race.

Cannabis use among college students is associated with negative consequences, including those that can negatively affect academic functioning. Perceived descriptive and injunctive norms are among the strongest predictors of college cannabis use and related problems, and perceived norms differentially relate to cannabis outcomes depending on the reference group (e.g., close friends, family members). However, no known studies have examined the effect of race on these relationships. Yet, given that African American students are more strongly affected by parental influence than Caucasian students and that they endorse more social motives for cannabis use, African American students may be affected by perceived norms regarding parents and friends differentially from Caucasian students. The current study tested the moderational role of race on the relationship between perceived norms and cannabis use and related problems. Cannabis-using undergraduates (N = 103; 78.6% female) completed an online survey. Race moderated the relationship between injunctive norms regarding parents and cannabis-related problem severity such that among African American students (but not Caucasian students), endorsement of more permissive perceived parental injunctive norms was related to greater cannabis-related problem severity (but not cannabis use frequency). Interactions were not significant between race and descriptive norms or between race and peer injunctive norms. African American students who perceive that their parents are more accepting of cannabis use may be especially at risk for cannabis-related problems. Results underscore the importance of considering cultural factors in identification of vulnerability factors related to cannabis problems.

The role of drinking motives and perceived controllability of events in the association between college women's sexual assault victimization and binge drinking.

Women with a history of sexual assault are at elevated risk for engaging in binge drinking. The aims of the current study are to investigate two types of drinking motives (coping and social) that potentially underlie the sexual assault-binge drinking link in a sample of female college drinkers (N = 691; 37.6% sexual assault prevalence), and to determine the extent to which the relationships between sexual assault history and each type of drinking motive depend on women's assumptions about the controllability of events. Conditional process analysis results indicated that women who experienced sexual assault (vs. those who did not) were more likely to report both coping and social drinking motives, which in turn, were both positively associated with increased binge drinking. Consistent with our hypothesis, results showed the relationship between sexual assault history and coping drinking motives was moderated by perceived controllability of events. Specifically, sexual assault victims reported high coping motives regardless of controllability of events. Nonvictims only reported high coping motives when their perceived controllability of events was low - comparable to coping motives of victims. This integrative approach affords a more comprehensive understanding of the context in which college women's binge drinking occurs, and offers insight into processes that could be targeted in interventions.

Drinking goals and attainment in a naltrexone trial of young adult heavy drinkers.

OBJECTIVE: Drinking goals set at treatment onset predict treatment outcome in patients with alcohol use disorders. Yet the cognitive constructs of goal setting and goal attainment are understudied in young adult drinkers. This study sought to examine how the interplay of goal setting and goal attainment during treatment impacts treatment outcome in a sample of young adult heavy drinkers. METHOD: Participants were 128 young adult heavy drinkers (Mage = 21.5 years) who participated in a double-blind, placebo-controlled, 8-week efficacy trial of naltrexone plus brief counseling. Participants were not required to be interested in changing their drinking for inclusion. Drinking goals were assessed at baseline, midtreatment, and end of treatment. Outcomes were peak drinking, typical drinking, and drinking frequency. RESULTS: Results from PROCESS serial, multiple mediator models showed that midtreatment goal setting and goal attainment collectively predicted peak drinking (b = 0.87, 95% CI [0.40, 1.37]) and drinking frequency (b = 0.66, 95% CI [0.37, 1.06]). Only midtreatment goal setting mediated the relationship between baseline goal setting and typical drinking (b = 0.35, 95% CI [0.10, 0.85]). Participants who set more ambitious drinking goals at baseline were more likely to set subsequent, ambitious goals; more ambitious goals at midtreatment were associated with better treatment outcomes. CONCLUSION: Setting initial, ambitious goals led to further ambitious goals, which ultimately contributed to lower levels of drinking. Thus, cognitive processes during treatment may be an important target of intervention efforts. For example, the inclusion of goal-setting exercises during treatment could serve to improve intervention effects. (PsycINFO Database Record

Longitudinal Associations Between Alcohol-Related Cognitions and Use in African American and European American Adolescent Girls.

BACKGROUND: African American (AA) girls initiate alcohol use later and drink less than European American (EA) girls, potentially reflecting differences in the development of drinking behaviors. This study examined alcohol-related cognitions: expectancies, attitudes, and intention to drink, as possible sources of variation by race in alcohol use. The aim of this study was to characterize the nature and degree of association between cognitions and use over time and by race in EA and AA girls. METHODS: Data were drawn from the longitudinal Pittsburgh Girls Study (N = 2,450), an urban population-based sample of girls and their caregivers recruited when girls were between ages 5 and 8, and assessed annually through adolescence. Cross-lagged panel models were conducted separately by race (56.2% AA, 43.8% EA) to identify patterns of association between alcohol use and cognitions from ages 12 to 17 in 2,173 girls. RESULTS: Endorsement of cognitions and use was higher overall in EA than AA girls but the magnitude of cross-lagged path coefficients did not differ significantly by race. In both groups, bidirectional effects emerged between intentions and use, and alcohol use largely predicted cognitions across ages. However, intention to drink was the only alcohol-related cognition that consistently predicted subsequent use (odds ratios ranged from 1.55 to 2.71). CONCLUSIONS: Although rates of alcohol use and endorsement of cognitions were greater in EA than AA girls, the anticipated racial differences in longitudinal associations between cognitions and use did not emerge, indicating that variation in associations between use and cognitions does not account for the lower prevalence of alcohol use in AA compared with EA girls. Furthermore, our finding that intention to drink is a consistent, robust predictor of subsequent alcohol use suggests the need to investigate potentially modifiable factors that influence intention to drink across racial groups.

Correlates of cannabis vape-pen use and knowledge among U.S. college students.

INTRODUCTION: The proliferation of electronic devices, such as vape-pens, has provided alternative means for cannabis use. Research has found cannabis-vaping (i.e., vape-pen use) is associated with lower perceived risks and higher cannabis use. Knowledge of these products may increase likelihood of subsequent use. As policies for cannabis shift, beliefs that peers and family approve of this substance use (injunctive norms) increase and there has been an increase in vape-pen use among young adults (18-35 year olds); however, correlates thereof remain unknown. Young adults often engage in cross-substance use with cannabis and alcohol, making alcohol a potential correlate of cannabis vape-pen use and knowledge. Therefore, we examined alcohol use and other potential correlates of vape-pen use and knowledge among a sample of university students. METHODS: This secondary data analysis utilized surveys at multiple colleges in the U.S. (N = 270). Alcohol use, social anxiety, cannabis expectancies, injunctive and descriptive norms and facets of impulsivity were examined as correlates of vape-pen use and knowledge using bivariate correlations and logistic regressions. RESULTS: Alcohol use was correlated with cannabis vape-pen use and knowledge. Frequency of cannabis use, peer injunctive norms, and positive expectancies were associated with increased likelihood of vape-pen use. Lack of premeditation, a facet of impulsivity, was associated with cannabis vape-pen knowledge. CONCLUSIONS: Given the unknown nature and consequences of cannabis vape-pens, the present findings offer valuable information on correlates of this behavior. Further, correlates of knowledge of vape-pens may point to areas for education and clinical intervention to prevent heavy cannabis vape-pen use.

Longitudinal associations between marijuana-related cognitions and marijuana use in African-American and European-American girls from early to late adolescence.

This study examined marijuana-related cognitions and marijuana use in African-American (AA) and European-American (EA) girls, with the aim of characterizing their interrelationships from early to late adolescence. Identifying differences by race in these relationships would have implications for tailoring interventions to specific subgroups. Data were drawn from the Pittsburgh Girls Study, an urban community sample (56.8% AA, 43.2% EA; n = 2,172) recruited at ages 5-8 years and assessed each year. Cross-lagged panel models were conducted separately by race to identify patterns of association between marijuana use and related cognitions (i.e., intentions to use, positive attitude toward use, positive and negative expectancies) assessed at ages 12-17 years. Results indicated that AA girls consistently reported higher negative expectancies than EA girls and greater intention to use marijuana, but they did not differ from EA girls on positive expectancies. In cross-lagged models, bidirectional effects between negative expectancies and marijuana use were observed in AA and EA girls across all ages, and at most ages for intentions to use, but were largely absent in both groups for positive attitude. Bidirectional effects of marijuana use with positive expectancies were observed only in AA girls at certain ages. Overall, results demonstrate more similarities than differences between AA and EA girls in the longitudinal associations between marijuana-related cognitions and marijuana use. Results highlight the role of negative expectancies as shaping and being shaped by marijuana use. Interventions that target negative expectancies to reduce marijuana use may be useful for AA and EA adolescent girls. (PsycINFO Database Record

Testing the nicotine dependence measure mFTQ for adolescent smokers: A multinational investigation.

BACKGROUND AND OBJECTIVES: As a measure of nicotine dependence among adolescent smokers, the modified Fagerström Tolerance Questionnaire (mFTQ; seven items), has been successfully used in the United States (USA). Nonetheless, the validity and reliability of mFTQ at the international level is still needed. The current study is the first to test the validity and reliability of mFTQ in four countries: Thailand, Spain, the USA, and Russia. METHODS: In a cross-sectional survey, mFTQ, risk factors of nicotine dependence, and sociodemographic characteristics were assessed. Risk factors included age of first cigarette, frequency of alcohol use, frequency of marijuana use, and number of cigarettes smoked yesterday. Salivary cotinine was also obtained in Thailand and Spain. RESULTS: For all four countries, mFTQ exhibited a single factor structure, as supported by previous work in the USA. For all studied countries except Thailand, mFTQ presented acceptable internal reliability. Overall, risk factors of nicotine dependence have predicted mFTQ scores across countries. Frequency of alcohol use in the USA and frequency of marijuana use in Thailand and Spain were not associated with mFTQ scores. DISCUSSION AND CONCLUSIONS: mFTQ is a single-factor measure of nicotine dependence that shows acceptable internal consistency and validity across countries. Further work can advance the scale and tailor it to different cultures. SCIENTIFIC SIGNIFICANCE: mFTQ can be a clinically practical international measure of nicotine dependence. This study provides initial support for the utility of the mFTQ among Thai, Spanish, American, and Russian adolescents. Further research is needed to test and advance mFTQ across cultures.

Acculturative stress as a moderator of the effect of drinking motives on alcohol use and problems among young adults.

BACKGROUND: Research has demonstrated a strong relationship between drinking motives and alcohol use among young adult populations. Further, there is substantial evidence of the association between psychosocial stressors and greater alcohol consumption. In the present study, we examined whether acculturative stress would moderate the relationship between major drinking motives and alcohol use behaviors and alcohol-related problems, and whether this relationship differs by racial/ethnic group. METHOD: Six hundred diverse undergraduate students (mean age=21.50, SD=2.46; 82.8% female; 40.2% White/Caucasian) completed a series of measures, including demographic information, alcohol use/alcohol problems, and acculturative stress. RESULTS: Findings showed varying patterns in the moderating effect of acculturative stress on the relationship between drinking motives and alcohol consumption and alcohol-related problems, particularly for self-identified Hispanic, Black, and Asian students. Stronger drinking motives were associated with greater alcohol consumption and alcohol-related problems, and this relationship was stronger among Asian and Hispanic students who reported higher levels of acculturative stress. For Black students, greater acculturative stress was observed to weaken the relationship between coping, enhancement, and conformity motives and alcohol drinking frequency. CONCLUSIONS: Results are discussed in terms of incorporating acculturative stress in the development of tailored alcohol use interventions for vulnerable young adults, such as certain ethnic minority and immigrant groups. Clinical implications include screening for acculturative stress in primary care and counseling centers and early intervention programs to identify young adults who may be at-risk for or currently experiencing alcohol problems.

Mechanisms Underlying Sex Differences in Cannabis Use.

PURPOSE OF THE REVIEW: Cannabis is the most commonly used illicit substance worldwide. In recent decades, highly concentrated products have flooded the market, and prevalence rates have increased. Gender differences exist in cannabis use, as men have higher prevalence of both cannabis use and cannabis use disorder (CUD), while women progress more rapidly from first use to CUD. This paper reviews findings from preclinical and human studies examining the sex-specific neurobiological underpinnings of cannabis use and CUD, and associations with psychiatric symptoms. RECENT FINDINGS: Sex differences exist in the endocannabinoid system, in cannabis exposure effects on brain structure and function, and in the co-occurrence of cannabis use with symptoms of anxiety, depression and schizophrenia. In female cannabis users, anxiety symptoms correlate with larger amygdala volume and social anxiety disorder symptoms correlate with CUD symptoms. Female cannabis users are reported to be especially vulnerable to earlier onset of schizophrenia, and mixed trends emerge in the correlation of depressive symptoms with cannabis exposure in females and males. SUMMARY: As prevalence of cannabis use may continue to increase given the shifting policy landscape regarding marijuana laws, understanding the neurobiological mechanisms of cannabis exposure in females and males is key. Examining these mechanisms may help inform future research on sex-specific pharmacological and behavioral interventions for women and men with high-risk cannabis use, comorbid psychiatric disease, and CUD.

Marijuana Use, Marijuana Expectancies, and Hypersexuality among College Students.

Research supports links between marijuana effect expectancies and risky sexual behaviors among marijuana users, but associations between marijuana expectancies and hypersexuality have yet to be investigated. The current study examined links between marijuana lifetime use and hypersexuality among university students. A hierarchical regression adjusting for gender and alcohol use was used to determine the degree to which marijuana use and expectancies accounted for variance in hypersexuality. Marijuana lifetime use and hypersexuality were significantly and positive related. After adjusting for covariates, perceptual and cognitive enhancement expectancies positively correlated with hypersexuality, while tension reduction and relaxation expectancies negatively correlated with hypersexuality.

Perceived safety and controllability of events: Markers of risk for marijuana use in young adults?

Drawing on constructs from the trauma literature, the current study evaluated perceptions of safety and controllability of events as potential markers of risk for marijuana use. In addition, we characterized these perceptions in relation to individual level substance abuse risk factors (marijuana expectancies, impulsivity, depression, and anxiety), gender, and race. Data were collected via web survey from college students at two northeastern universities (n=228, 82.0% female). Controllability of events (CE) was rated significantly higher by Blacks than Whites. Safety/vulnerability (SV) and CE were associated with impulsivity, depression, and anxiety. CE was also associated with marijuana expectancies. Logistic regression analyses revealed a modest but significant association between SV and lifetime use even after adjusting for race, gender, age, and individual level substance abuse risk factors (odds ratio=1.10, 95% confidence intervals:1.02-1.18). No association between SV and past 3month frequency of use or between CE and either marijuana outcome was found. Findings support a link between perceptions of safety and ever using marijuana. They further demonstrate overlap of both perceived safety and controllability of events with substance use related risk factors, and suggest that they differ by race. Additional studies that assess substance use more broadly and query trauma history, using larger, more diverse samples, are needed to more fully grasp the relevance of these constructs to substance use, including their potential as targets for substance abuse prevention efforts.

The influence of drinking motives on hookah use frequency among young multi-substance users.

PURPOSE: The present work examined the influence of drinking motives on hookah use frequency among individuals reporting both alcohol and hookah use (multi-substance users). Despite growing documentation of cross-substance effects between motives and substance use, limited research has examined these relationships specifically with respect to hookah use. METHODS: Participants were 134 (75.37% female) hookah and alcohol users, aged 18-47 years (M = 22.17, SD = 3.66) who completed measures of substance use, drinking motives, and reported demographic information. Structural equation modeling (SEM) was employed to investigate the predictive value of drinking motives on hookah use frequency, age taken into account. RESULTS: Findings showed that hookah use was negatively associated with age (ß = -.22, p ≤ .01). The model regressing hookah use on the four drinking motives provided adequate fit (χ2 = 314.31, df = 180, p < .05, CFI = .92, RMSEA = .075 [95% CI, .06-.09]). Hookah use was associated negatively with social motives (ß = -.43, p < .001) and positively with conformity motives (ß = .24, p ≤ .05). CONCLUSIONS: These findings are consistent with multi-substance use literature suggesting that drinking motives are associated with the use of other substances, including increased hookah use frequency. Additional examinations of cross-substance cognitive processes are needed, particularly with respect to understanding whether hookah use among multi-substance users may be contingent in part on individual factors including negative affectivity.

Compounding risk: An examination of associations between spirituality/religiosity, drinking motives, and alcohol-related ambivalence among heavy drinking young adults.

OBJECTIVES: The present study assessed combinations of spirituality/religiosity (S/R), a known protective factor against heavy drinking, with drinking motives, and alcohol-related ambivalence to better understand how these factors interrelate and are associated with drinking and alcohol-related problems. METHODS: Participants were 241 heavy drinking undergraduate students (81.74% female; Mage=23.48years; SD=5.50) who completed study questionnaires online. RESULTS: Coping, enhancement, and conformity drinking motives were associated with greater alcohol use and problems, however there were no main effects of either ambivalence or S/R on alcohol outcomes. S/R interacted with ambivalence with respect to drinking and problems. S/R also interacted with conformity drinking motives with respect to drinking and problems. Further, ambivalence interacted with conformity drinking motives regarding problems. Three-way interactions emerged between ambivalence, S/R, and drinking motives (social, coping, and enhancement motives) regarding drinking and problems. Results show that individuals at highest risk for problematic drinking are those who more strongly endorse drinking motives, are low in S/R, and high in ambivalence. CONCLUSIONS: Findings supported hypotheses and provide support for clusters of individual difference factors that put heavy drinking college students at higher risk for problematic drinking. These examinations have practical utility and may inform development and implementation of interventions and programs targeting alcohol misuse among heavy drinking undergraduate students.

The Interactive Influence of Cannabis-Related Negative Expectancies and Coping Motives on Cannabis Use Behavior and Problems.

OBJECTIVES: The present study tested whether coping motives for cannabis use moderate the effect of negative expectancies on cannabis use. METHODS: Participants were 149 (36.2% female, 61.59% non-Hispanic Caucasian) current cannabis users aged 18-36 (M = 21.01, SD = 3.09) who completed measures of cannabis-related expectancies and motives for use. Hierarchical multiple regressions were employed to investigate the predictive value of the interaction between negative expectancies and coping motives on cannabis use outcomes. RESULTS: Results revealed interactions between negative expectancies and coping motives with respect to past 90 day cannabis use frequency and cannabis problems. Global negative effects expectancies were associated with less frequent cannabis use, particularly among those with fewer coping motives. However, negative expectancies were related to more cannabis problems, particularly among those with higher coping motives. CONCLUSIONS: These results suggest it may be advisable to take coping motives into account when addressing expectancies among cannabis users.

Social Anxiety and Cannabis-Related Impairment: The Synergistic Influences of Peer and Parent Descriptive and Injunctive Normative Perceptions.

OBJECTIVES: Cannabis users, especially socially anxious cannabis users, are influenced by perceptions of other's use. The present study tested whether social anxiety interacted with perceptions about peer and parent beliefs to predict cannabis-related problems. METHODS: Participants were 148 (36.5% female, 60.1% non-Hispanic Caucasian) current cannabis users aged 18-36 (M = 21.01, SD = 3.09) who completed measures of perceived descriptive and injunctive norms, social anxiety, and cannabis use behaviors. Hierarchical multiple regressions were employed to investigate the predictive value of the social anxiety X parent injunctive norms X peer norms interaction terms on cannabis use behaviors. RESULTS: Higher social anxiety was associated with more cannabis problems. A three-way interaction emerged between social anxiety, parent injunctive norms, and peer descriptive norms, with respect to cannabis problems. Social anxiety was positively related to more cannabis problems when parent injunctive norms were high (i.e., perceived approval) and peer descriptive norms were low. Results further showed that social anxiety was positively related to more cannabis problems regardless of parent injunctive norms. CONCLUSIONS: The present work suggests that it may be important to account for parent influences when addressing normative perceptions among young adult cannabis users. Additional research is needed to determine whether interventions incorporating feedback regarding parent norms impacts cannabis use frequency and problems.

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.
