Moderating effects of sensitivity to punishment and sensitivity to reward on associations between marijuana effect expectancies and use.

The study examined associations between sensitivity to reward (SR), sensitivity to punishment (SP), positive and negative expectancies, and marijuana use in a college sample (N = 809). Marijuana users (n = 227) reported lower SP and greater SR than nonusers. SR attenuated the association between SP and the probability of marijuana use. SP attenuated the association between positive expectancies and the probability of marijuana use as well as the frequency of use among users. SP potentiated the association between negative expectancies and use. The results indicate that SP and SR have interactive effects and that SP moderates the strength of positive and negative cues for risk behavior.

Alcohol-related infractions among college students: Associations with subsequent drinking as a function of sensitivity to punishment.

Problematic alcohol use on college campuses is a significant concern. Violations of campus alcohol policies can lead to disciplinary action from the university. These and other alcohol-related legal infractions may be a sign of significant alcohol-related problems. However, few studies have focused on determining predictors of alcohol-related infractions among college students. Likewise, the role of infractions in reducing future use is unclear. In the present study, we tested whether alcohol-related infractions were associated with decreased alcohol use, and whether the effect of the infraction varied as a function of initial drinking levels, sensitivity to punishment (SP), and sensitivity to reward (SR) in a 6-month prospective design. Alcohol use, grade point average, and SR were significantly associated with receiving an alcohol-related infraction. For heavier drinkers, receiving an infraction was associated with decreased drinking at follow-up, and this decrease was most pronounced among those with higher sensitivity to punishment. SP appeared to increase responsiveness to the infraction, resulting in greater attenuation of drinking at follow-up. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Families and risk: prospective analyses of familial and social influences on adolescent substance use.

Parental, peer, and older siblings' contributions to adolescents' substance use were investigated with 2 waves of panel data from 225 African American families. Structural equation modeling showed that older siblings' behavioral willingness (BW) to use substances at Time 1 (T1) predicted target adolescents' Time 2 (T2) use, controlling for other T1 variables. Regression analyses revealed an interaction between targets' and siblings' BW, such that targets were more likely to use at T2 if both they and their siblings reported BW at T1. This interaction was stronger for families living in high-risk neighborhoods. Finally, siblings' willingness buffered the impact of peer use on targets' later use: Low sibling BW was associated with less evidence of peer influence.

Drug testing, drug treatment, and marijuana use: A fairness perspective.

The authors conducted a random statewide telephone survey of 1,484 individuals to study the relationship between marijuana use (in terms of participants' history of marijuana use) and reactions to drug testing and to study 2 hypothetical drug-treatment policies. Job safety sensitivity was related to perceived fairness of drug testing for the participant's job, and more recent marijuana use was associated with more negative reactions. Safety sensitivity was related to perceived fairness of drug treatment. Organizations with voluntary treatment were more attractive than ones with monitored treatment. Marijuana use interacted with drug treatment policy type in predicting reactions to drug treatment. Results suggest that organizations should consider job and employee characteristics when developing a drug treatment policy. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Relations between anxiety sensitivity, distress tolerance, and fear reactivity to bodily sensations to coping and conformity marijuana use motives among young adult marijuana users.

The present investigation examines anxiety sensitivity, distress tolerance, and fear reactivity to bodily sensations in relation to Coping and Conformity marijuana use motives among a sample of young adult marijuana users (n = 135; 46.7% women; Mage = 20.45, SD = 5.0). After controlling for current marijuana use frequency (past 30 days), daily cigarette smoking rate, average volume of alcohol used over the past year, negative affectivity, and other marijuana use motives, anxiety sensitivity was significantly and uniquely associated with Coping and Conformity motives for marijuana use. Distress tolerance evidenced significant and unique incremental relations to Coping motives, whereas fear reactivity to bodily sensations was unrelated to any marijuana use motive. These results provide novel information related to the role of emotional sensitivity and tolerance factors as they pertain to specific types of motives for marijuana use among young adults.

Risk and vulnerability for marijuana use problems: The role of affect dysregulation.

This study examined the moderating effects of impulsivity and affect lability on relations between marijuana use frequency and use consequences. From a sample of 592 undergraduates, 300 marijuana users completed a survey that assessed marijuana problems and the hypothesized risk and vulnerability factors. Affective variables were significantly associated with increased marijuana problems above and beyond the effects of gender and lifetime use frequency. A hypothesized vulnerability mechanism, whereby impulsivity strengthened the relationship between use frequency and marijuana problems, was observed. The findings support the hypothesis that affect dysregulation enhances risk for marijuana problems among young adults who use marijuana.

Latent growth modeling of the relationship between depressive symptoms and substance use during adolescence.

To explicate the nature of the relationship between depressive symptoms and substance use, the authors conducted research that incorporated both individual and group approaches and utilized longitudinal data across development. Multiple-group latent growth curve models were used to assess specific dimensions (cross-sectional and longitudinal correlation, within-individual change, and movement off developmental trajectories) of the relationship between depressive symptoms and substance use during adolescence and how this relationship differs by gender. Annual survey data from 8th through 11th grade were provided by 441 girls and 510 boys in the Raising Healthy Children project (E. C. Brown, R. F. Catalano, C. B. Fleming, K. P. Haggerty, & R. D. Abbott, 2005). Levels of depressive symptoms and substance use in early adolescence were positively associated for alcohol, marijuana, and cigarette use for girls, but only for marijuana use for boys. Individual changes in depressive symptoms and substance use across adolescence were positively associated for each type of substance use. Evidence was also found for positive association between episodic expressions of depressive symptoms and alcohol use that fell outside developmental trajectories. Predictive relationships across constructs were not found, with the exception of higher level of depressive symptoms in early adolescence predicting less increase in alcohol use.

Online communication, compulsive internet use, and psychosocial well-being among adolescents: A longitudinal study.

The present study investigated the relationships between adolescents' online communication and compulsive Internet use, depression, and loneliness. The study had a 2-wave longitudinal design with an interval of 6 months. The sample consisted of 663 students, 318 male and 345 female, ages 12 to 15 years. Questionnaires were administered in a classroom setting. The results showed that instant messenger use and chatting in chat rooms were positively related to compulsive Internet use 6 months later. Moreover, in agreement with the well-known HomeNet study (R. Kraut et al., 1998), instant messenger use was positively associated with depression 6 months later. Finally, loneliness was negatively related to instant messenger use 6 months later. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A short-term longitudinal study of Internet and computer game use by adolescent boys and girls: Prevalence, frequency of use, and psychosocial predictors.

Prevalence, frequency, and psychosocial predictors of Internet and computer game use were assessed with 803 male and 788 female adolescents across 2 time periods, 21 months apart. At Time 1, participants were in the 9th or 10th grade; at Time 2, they were in the 11th or 12th grade. Most girls (93.7%) and boys (94.7%) reported using the Internet at both time periods, whereas more boys (80.3%) than girls (28.8%) reported gaming at both time periods. Girls reported a small decrease over time in the frequency of hours spent per day on overall technology use, mostly due to a decrease in gaming. Both linear and curvilinear relations were examined between parental relationships, friendship quality, academic orientation, and well-being measured in early high school and the frequency of technology use in late high school. Being male significantly predicted both computer gaming and Internet use. There also were trends in favor of higher friendship quality and less positive parental relationships predicting higher frequency of Internet use. Importantly, moderate use of the Internet was associated with a more positive academic orientation than nonuse or high levels of use.

Validating a five-factor marijuana motives measure: Relations with use, problems, and alcohol motives.

This study adapted and extended M. L. Cooper's (1994) Drinking Motives Measure to examine marijuana motives among 299 college students. An exploratory factor analysis supported the hypothesized 5-factor marijuana motives model, resulting in enhancement, conformity, expansion, coping, and social motives. Analyses supported the internal consistency and concurrent validity of the 5 marijuana motives. Marijuana motives were significant predictors of marijuana use and added to the prediction of use-related problems above and beyond the contribution of lifetime use. Motives and gender interacted in predicting use and use-related problems. Parallel regression analyses revealed that marijuana and alcohol motives predicted comparable amounts of variance in use and use-related problems. However, different patterns of relations emerged across drugs, supporting the discriminant validity of the marijuana and alcohol motives.

Expectancy change and adolescents' intentions to use marijuana.

Drug prevention campaigns commonly seek to change outcome expectancies associated with substance use, but the effects of violating such expectancies are rarely considered. This study details an application of the expectancy violation framework in a real world context by investigating whether changes in marijuana expectations are associated with subsequent future marijuana intentions. A cohort of adolescents (N = 1,344; age range = 12?18 years) from the National Survey of Parents and Youth was analyzed via secondary analysis. Nonusers at baseline were assessed 1 year later. Changes in expectancies were significantly associated with changes in intentions (p     

The role of physical health functioning, mental health, and sociodemographic factors in determining the intensity of mental health care use among primary care medical patients.

The present study examined sociodemographic and attitudinal predisposing factors (gender, age, marital status, health insurance, household income, attitudes about mental health care), and need/illness variables (depression severity, physical and mental health functional status) as predictors of past-year mental health care use intensity (i.e., visit counts) and use/nonuse. The sample included 283 adult primary care patients from the Midwestern United States in a cross-sectional study. Nonlinear regression models demonstrated that past-year treatment use intensity was significantly associated with both married status and poorer physical health functioning, while the use (vs. nonuse) of treatment was associated with depression severity. A sociodemographic and attitudinal multivariate predictor model only explained 5% of the variance in treatment use intensity, but a need/illness model significantly contributed an additional 23% variance. Poorer physical health functioning was significant in predicting treatment use intensity, while depression severity was significant in predicting the use (vs. nonuse) of treatment. Results demonstrate the particular importance of physical health problems in determining the intensity of mental health care use, and depression severity in determining the use/nonuse of treatment, notwithstanding the restricted sociodemographic contour of the sample.

Time perspective and early-onset substance use: A model based on stress–coping theory.

This research tested the relation of time perspective to early-onset substance use (tobacco, alcohol, and marijuana) with a sample of 454 elementary school students with a mean age of 11.8 years. An adaptation of the Zimbardo Time Perspective Inventory (P. G. Zimbardo & J. N. Boyd, 1999) was administered with measures derived from stress-coping theory. Independent effects showed future orientation inversely related to substance use and present orientation positively related to substance use. Structural modeling analysis indicated that the relation of time perspective measures to substance use was indirect, mediated through behavioral coping and anger coping. Proximal factors for substance use were negative affect, peer substance use, and resistance efficacy. Results are discussed with respect to epigenetic models and the role of executive functions in self-control ability. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Evaluations and expectancies of alcohol and marijuana problems among college students.

Two studies examined the associations between evaluations (good-bad) and expected likelihood (likely-unlikely) of alcohol- and marijuana-related problems and hazardous consumption and problems among college students. Participants provided data on alcohol use, alcohol-related problems, and expectancies and evaluations of alcohol problems; marijuana use indices, marijuana-related problems, marijuana effect expectancies, and likelihood and evaluations of marijuana problems. Evaluations of alcohol problems were positively related to the number of binge drinking occasions and alcohol-related problems. The interaction between evaluations and expectancies was significant in predicting the number of binge drinking occasions. Expectancies demonstrated a curvilinear relationship with binge drinking and alcohol-related problems. Marijuana users evaluated marijuana-related problems as less negative and less likely to occur than did nonusers. Expectancies, but not evaluations, of negative consequences were significantly associated with marijuana use intensity. Expectancies of problems demonstrated a curvilinear relationship with marijuana-use intensity and marijuana problems. Men evaluated alcohol and marijuana problems less negatively than did women. In summary, the expected likelihood of alcohol-marijuana problems and the evaluation of such problems represent a vulnerability factor associated with increased liability for hazardous alcohol and marijuana use.

Age-related changes in reasons for using alcohol and marijuana from ages 18 to 30 in a national sample.

This study used up to seven waves of data from 32 consecutive cohorts of participants in the national longitudinal Monitoring the Future study to model changes in self-reported reasons for using alcohol and marijuana by age (18 to 30), gender, and recent substance use. The majority of stated reasons for use decreased in prevalence across young adulthood (e.g., social/recreational and coping with negative affect reasons); exceptions included age-related increases in using to relax (alcohol and marijuana), to sleep (alcohol), because it tastes good (alcohol), and to get high (marijuana). Women were more likely than men to report drinking for reasons involving distress (i.e., to get away from problems), while men were more likely than women to endorse all other reasons. Greater substance use at age 18 was associated with greater likelihood of all reasons except to experiment and to fit in. A better understanding of developmental changes in reasons for use is important for understanding normative changes in substance use behaviors and for informing intervention efforts involving underlying reasons for use.

CD4 and CD8 counts are associated with interactions of gender and psychosocial stress

OBJECTIVE: This study examined relationships of gender, psychosocial stress/distress (caregiving, hassles, depressed mood), and the relative percentage and absolute cell counts of CD4 and CD8 cells in two samples of older adults (mean age = 69.4)--spouse caregivers of persons with Alzheimer's disease (N = 78) and age- and gender-matched spouses of nondemented controls (N = 72). METHODS: Counts and percentages of CD4 and CD8 cells and psychosocial variables were assessed twice (Time 1, Time 2) over a 15- to 18-month period. Several covariates were examined in the analyses, including body mass index (BMI), medication use, alcohol use, exercise, and illness history. RESULTS: Caregiver men had fewer CD4 cell counts at Times 1 and 2 than did control men (p < .05). At Times 1 and 2, both CD8 cell counts and percentages were positively associated with hassles in men (p < .05), but not in women. Although interactions of hassles and gender were present for CD8 percentages at both times, interactions and main effects were not present for CD4 percentages at either time. When the ratio of CD4 to CD8 levels was analyzed, hassles by gender interactions were present at both Times 1 and 2-hassles were negatively associated with the CD4/CD8 ratio in men (p < .05), but unrelated in women. From Time 1 to Time 2, change analyses showed that increases in hassles scores were associated with decreases in CD4 counts (p < .05), whereas increases in Hamilton Depression Scores were related to increases in both CD8 counts and percentages (p < .05). CONCLUSION: Caregiver status, hassles, and depressed mood had cross-sectional and/or longitudinal associations with CD4 and CD8 counts, but such relationships occurred primarily in men. Moreover, absolute cell counts were more related to psychosocial factors than were percentages.     

Effects of work overload and burnout on cholesterol and triglycerides levels: The moderating efffects of emotional reactivity among male and female employees.

The effects of objective and subjective overload, and of physical and emotional burnout, on cholesterol and triglycerides levels were studied in a quasiprospective design. The possible moderating effects of emotional reactivity on these relationships were also investigated. The study's hypotheses were tested separately for male and female employees. Time I (T1) data were collected from 665 healthy employees (30% women) while they were undergoing periodic health examinations in a health-screening center Time 2 (T2) measures of cholesterol and triglycerides were collected 2 to 3 years after T1. The hypotheses were tested by regressing each T2 criterion on its T1 level; the control variables of age, obesity, diet, alcohol consumption, and smoking; and the other predictors. For female employees, the T2-T1 changes in the serum lipids were positively predicted by emotional burnout, as expected, but negatively predicted by physical fatigue. For male employees, both types of T1 burnout were positive predictors of the T2-T1 change in total cholesterol. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Acculturation, Familism, Parental Monitoring, and Knowledge as Predictors of Marijuana and Inhalant Use in Adolescents.

The authors investigated relationships between marijuana and inhalant use and several cultural and demographic factors in Anglo American and Hispanic American adolescents (N=1,094). Outcome measures assessed lifetime and 30-day marijuana and inhalant use. Predictors and covariates used in logistic regression analyses were region, grade, gender, knowledge, acculturation, familism, and parental monitoring. Hispanic Americans exhibited higher usage across all measures. In this group, high acculturation was associated with low marijuana, but high inhalant, use. Across all participants, positive family relations and parental monitoring were strongly associated with attenuated marijuana use hut only among those most knowledgeable about drugs. Familism and monitoring were not associated with diminished usage among the less knowledgeable. For inhalants, monitoring combined with high knowledge or high familism was associated with diminished usage. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Young-adult malt liquor drinkers: Prediction of alcohol problems and marijuana use.

Malt liquor (ML) is a cheap, high alcohol content beverage that is marketed to appeal to young adults. Findings from the few published studies of ML use suggest that it may be associated with excessive drinking, alcohol problems, and the use of illicit drugs. The authors conducted separate hierarchical multiple regressions to examine the role of ML use and psychosocial variables (e.g., personality, ML motives) in alcohol-related problems and marijuana use. Demographic characteristics served as controls. The sample consisted of 639 (456 men, 183 women) young adults (M = 22.9 years, SD = 4.2) who regularly (≥40 oz/week) consumed ML. ML use significantly and positively predicted alcohol problems, ML-specific problems, and marijuana use, above and beyond their associations with typical alcohol use. Marijuana was the illicit drug of choice, and 46% reported concurrent use of marijuana and ML. Those who concurrently used ML and marijuana began drinking at a younger age and reported more substance use (particularly marijuana) and more alcohol-related problems than did nonconcurrent users. These results suggest that ML use may represent a risk for alcohol problems and marijuana use. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
