RESUMO
Objective: Alcohol misuse is prevalent and clinically significant among college students. Psychological distress is one factor that has been found to predict alcohol misuse in this population. However, relatively few investigations examined the association of psychological distress to alcohol misuse or its underlying mechanisms among students attending historically Black colleges and universities (HBCUs). The present study examined whether impulsivity explains the relation between psychological distress and alcohol misuse in this population using structural equation modeling. Methods: Participants were 287 undergraduate students attending an HBCU in the southern United States (Mage = 22.5, 66.3% female, 93.7% Black). Results: Impulsivity was found to significantly mediate the association of psychological distress to alcohol misuse, such that higher levels of psychological distress were associated with greater impulsivity which, in turn, was related to more alcohol misuse. Further analyses indicated that attentional impulsivity significantly mediated the association of psychological distress to alcohol misuse. Conclusions: These findings suggest the utility of targeting impulsivity in interventions aimed at preventing and reducing alcohol misuse among college students attending HBCUs who experience psychological distress.

Steroid hormone analysis in blow (respiratory vapor) may provide a minimally invasive way to assess the reproductive status of wild cetaceans. Biological validation of the method is needed to allow for the interpretation of hormone measurements in blow samples. Utilizing samples collected from trained belugas (Delphinapterus leucas, n=20), enzyme immunoassays for testosterone and progesterone were validated for use with beluga blow samples. Testosterone concentrations in 40 matched blood and blow samples collected from 4 male belugas demonstrated a positive correlation (R2=0.52, p<0.0001). Progesterone concentrations in 64 matching blood and blow samples from 11 females were also positively correlated (R2=0.60, p<0.0001). Testosterone concentrations (mean±SD) in blow samples collected from adult males (119.3±14.2pg/ml) were higher (p<0.01) than that of a juvenile male (<8years) (59.4±6.5pg/ml) or female belugas (54.1±25.7pg/ml). Among adult males, testosterone concentrations in blow demonstrated a seasonal pattern of secretion, with peak secretion occurring during the breeding season (February-April, 136.95±33.8pg/ml). Progesterone concentrations in blow varied by reproductive status; pregnant females (410.6±87.8pg/ml) and females in the luteal phase of the estrous cycle (339.5±51.0pg/ml) had higher (p<0.0001) blow progesterone concentrations than non-pregnant females without a corpus luteum (242.5±27.3pg/ml). Results indicate that blow sample analysis can be used to detect variation in reproductive states associated with large differences in circulating testosterone or progesterone in belugas.

BACKGROUND: Reliable, valid and theoretically consistent measures that assess a parent's self-efficacy for helping a child with obesity prevention behaviors are lacking. OBJECTIVES: To develop measures of parental self-efficacy for four behaviors: 1) helping their child get at least 60 minutes of moderate intensity physical activity every day, 2) helping one's child consume five servings of fruits and vegetables each day, 3) limiting sugary drinks to once a week, and 4) limiting consumption of fruit juice to 6 ounces every day. METHODS: Sequential methods of scale development were used. An item pool was generated based on theory and qualitative interviews, and reviewed by content experts. Scales were administered to parents or legal guardians of children 4-10 years old. The item pool was reduced using principal component analysis. Confirmatory factor analysis tested the resulting models in a separate sample. SUBJECTS: 304 parents, majority were women (88%), low-income (61%) and single parents (61%). Ethnic distribution was 40% Black and 37% white. RESULTS: All scales had excellent fit indices: Comparative fit index> .98 and chi-squares (Pediatrics 120 Suppl 4:S229-253, 2007) = .85 - 7.82. Alphas and one-week test-retest ICC's were ≥.80. Significant correlations between self-efficacy scale scores and their corresponding behaviors ranged from .13-.29 (all p < 0.03). CONCLUSIONS: We developed four, four-item self-efficacy scales with excellent psychometric properties and construct validity using diverse samples of parents. CLINICAL TRIAL REGISTRATION: NCT01768533.

OBJECTIVE: The study explored food items that contribute most toward increased fermentable carbohydrate (FC) intake and its association with diet quality in college students. METHOD: This cross-sectional study included 571 consented college students (≥18 years) with reported energy intakes (500-3500 kcal/day for women; 800-4000 kcal/day for men). FC intake and healthy eating index-2015 (HEI-2015) scores were assessed by diet history questionnaire-II. Data were analyzed by unadjusted bivariate linear regression and Pearson correlation tests. RESULTS: The mean intakes of total FC (ß = 1.24; 95% Confidence Interval: 1.02, 1.47) significantly predicted HEI-2015 scores. Positive correlations were found between FC intake and red and orange vegetables (r = 0.62), whole fruits (r = 0.63), and dark green vegetables (r = 0.58). Conclusions: Higher FC intake was associated with higher diet quality; vegetables and fruits are primary contributors to FC content. Efforts are required to promote these food items to improve diet quality and FC intake to shape eating choices in college students.
RESUMO
OBJECTIVES: With alcohol-related problems remaining a concern on college campuses, prevention efforts are increasingly directed to addressing the environmental factors that encourage consumption. This study examined students' support for alcohol control policies, correlates of that support, and actual vs. perceived peer support. METHODS: Telephone interviews were conducted with a random sample of 510 college students. We conducted a three-step hierarchical regression analysis to examine predictors of policy support. Levels of personal and perceived peer support for alcohol control policies were compared. RESULTS: Findings revealed a high level of policy support among students, with variability in support by gender, alcohol consumption levels, and drinking and driving tendencies. Additionally, compared to the percentage of students who supported each policy, a smaller percentage thought other students were supportive. CONCLUSIONS: Results provide valuable insights to inform the development of media campaigns and other environmental management initiatives.

OBJECTIVES: Our study examined the impact of adherence to novel oral anticoagulants [NOACs - dabigatran and rivaroxaban] on ischemic-stroke (IS), major-bleeding (MB), deep-vein-thrombosis and pulmonary-embolism (DVTPE) risk in a large, nationwide, propensity-matched sample. METHODS: A retrospective cohort study utilized data from a US commercial managed-care database (2010-2012). Adult patients with ≥1 diagnosis of atrial fibrillation/flutter (ICD-9 427.31/32), >1 prescription of NOACs and CHA2DS2-VASc score ≥1 were included. Patients were categorized as adherent versus nonadherent (using proportion of days covered [PDC ≥80%]) based on their NOAC use up to 6 months and those continued its use up to 12 months. The patients were matched using propensity score (based on inverse probability treatment weighting) and the risk of IS, MB, DVTPE outcomes was evaluated for the matched cohorts' post-adherence (exposure) assessment using multivariable Cox regression. RESULTS: A total of 3,629 and 1,946 patients with at least 6 and 12 months of NOAC use were included. Based on a PDC threshold of ≥80%, adherence rates at 6 and 12 month usage were 77% and 76%, respectively. Patients with lowest adherence were from the South, had low stroke risk and EPO/HMO insurance. Using Cox models with matched cohorts, nonadherence within the first 6 months' use was significantly associated with higher risk of IS and DVTPE (IS: hazard ratio [HR] = 1.82, p = .002; DVTPE: HR = 2.12, p = .010) and the risk increased with nonadherence for the prolonged period of 12 months' use (IS: HR = 2.08, p = .022; DVTPE: HR = 5.39, p = .003). The risk of MB was not different (p > .05) between adherent and nonadherent groups for both 6 month and 12 month cohorts. CONCLUSION: Adherence to NOACs for both 6 months and prolonged use (up to 12 months) was associated with a reduction in IS and DVTPE risk, but did not substantially increase risk of MB. Further studies on newer, individual NOACs and older populations are warranted.

The Smoking Policy Inventory (SPI) is a 35-item scale, which measures attitudes towards tobacco control policies. The five dimensions of the SPI are advertising and promotion, public education, laws and penalties, taxes and fees, and restrictions on smoking. The SPI has been applied to different samples, both in the USA and internationally. However, no one has investigated if there is differential support for policy intervention among subgroups within the USA. This study investigated subgroup differences on five demographic variables (gender, age, race, ethnicity, and education) across the five dimensions of the SPI. A random digit dial sample of 506 adult participants from the United States was analyzed with five MANOVAs and follow-up ANOVAs. Men (N=188) had significantly (p<0.05) less favorable attitudes towards tobacco control policies than women (N=317) on all five scales. Blacks (N=52) had significantly (p<0.05) more favorable attitudes than whites (N=410) on increasing public education. There were no significant differences between Hispanics (N=21) and non-Hispanics (N=469). Older people were significantly (p<0.05) more supportive of restrictions on advertising and promotion, increasing public education, and increasing environmental restrictions. More educated people were significantly (p<0.05) more supportive of increasing taxes and fees and increasing environmental restrictions. These subgroup differences could be employed to guide the targeting of changes in policies and interventions to the specific concerns of the various groups.

This longitudinal study compared 14 principles and processes of change applied by successful quitters, relapsers and non-quitters over 24 months in a representative sample of 4144 smokers in intervention and control groups. The successful quitters showed a decrease in the use of experiential processes (cognitive, affective and effective) and an increase in behavioral processes (e.g., counter-conditioning and stimulus control). The non-quitters showed little change in their use of almost all of the processes. The relapsers' use of the processes tended to initially parallel the successful quitters, but over time, their use ended up between the quitters and the non-quitters. In general, the relapsers ended up working harder but not smarter than the successful quitters. The pattern of use of change processes in the treatment and control groups were remarkably similar, suggesting common pathways to change.

OBJECTIVES: The objective of this study was to assess the prevalence of binge drinking and its relation to other health behaviors, drinking-related attitudes and perceived social norms among German medical students. METHODS: 271 first-year German medical students completed a cross-sectional, self-administered survey. A total of 252 (62% female and 38% male) students provided useable surveys. The mean age was 20.6years (S.D.=1.7). RESULTS: Most students reported heavy drinking with 24% having one episode in the past 2 weeks (Infrequent Bingers) and 28% having two or more episodes (Frequent Bingers). Men were more likely than women to have had a binge drinking episode. Frequent binge drinkers saw more pros of drinking and reported a higher temptation to drink than students in the other groups. Additionally, they were more likely to smoke, use cannabis, not exercise and not eat fruits and vegetables. All students overestimated their peers' alcohol intake and binge drinking frequency. CONCLUSIONS: Binge drinking was highly prevalent in this sample and clearly related to other health risk behaviors. Drinking rates were similar to college students in other Western countries. Future research needs to assess the consequences of this multiple risk behavior among medical students regarding academic and professional performance as well as personal health.

This study is the first reported test of the unique and combined effects of Brief Motivational Intervention (BMI) and Alcohol Expectancy Challenge (AEC) with heavy drinking college students. Three hundred and thirty-five participants were randomly assigned in a 2x2 factorial design to either: BMI, AEC, BMI and AEC, and assessment only conditions. Follow-ups occurred at 1, 3, and 6 months. Unconditional latent curve analyses suggested that alcohol use (Q-F), heavy episodic drinking, and alcohol problems were best modeled as quadratic effects. BMI produced significant decreases in Q-F, heavy drinking, and problems, while AEC produced significant decreases in Q-F and heavy drinking. There was no evidence of an additive effect of combining the interventions. Intervention effects decayed somewhat for BMI and completely for AEC over 6 months. Multi-group analyses suggested similar intervention effects for men and women. BMI effects on alcohol problems were mediated by perceived norms. These findings extend previous research with BMI and AEC but do not support their utility as a combined preventive intervention to reduce collegiate alcohol abuse.

OBJECTIVE: Collateral informants have been used to assess independently the validity of college student self-report data. However, it is unclear under what conditions collateral reports might be valid and useful in college research. We present two studies that examine aspects of these issues using data from 1,264 college student participants in a brief intervention prevention trial conducted at a public university. METHOD: The first study describes the characteristics and predictors of agreement on reports of alcohol use and problems from 219 student-collateral informant pairs. The second study investigates potential "pipeline effects"; that is, whether collateral verification resulted in changes in student self-reports on two subsequent survey assessments over 1 year using longitudinal data from 1,264 students. RESULTS: Little support was found for the assumption that nondependent college drinkers underreport drinking behaviors and consequences. Collaterals who reported more occasions of drinking together, higher confidence in the report and a close relationship with the participant provided reports that were more consistent with participant drinking reports. No evidence was found that pipeline effects of collateral verification improve the accuracy of college student self-reports at future assessments. CONCLUSIONS: The results from this study are consistent with much of the published literature showing that using collateral reports to verify the self-reports of college students (and adults) may result in increased, not decreased, misclassification error. These findings suggest that the time and expense required to collect collateral data in the college setting has limited utility and may be better spent on establishing the proper assessment conditions that will foster accurate and honest self-reporting.

OBJECTIVE: To assess the validity of 5 parental stage-of-change (SOC) measures: (1) providing 5 servings/d of fruits and vegetables (FV), (2) limiting television (TV) to 2 h/d, (3) helping children achieve 1 h/d physical activity (PA), (4) limiting sugary drinks (SD) to 1 serving/wk, and (5) limiting fruit juice (FJ) to 4-6 oz/d. DESIGN: Cross-sectional instrument development study. Construct validity was evaluated by examining whether parental self-efficacy, parental readiness ladder (ladder), and child's behavioral levels (eg, FV consumption) exhibited a theoretically consistent pattern across the SOC. SETTING/PARTICIPANTS: Convenience sample (n = 283) of parents of children aged 4-10 years. MEASURES: Survey assessed SOC, ladder, and child's behavioral level score for each topic (FV, TV, PA, SD, and FJ), and parental self-efficacy for measure except TV. ANALYSIS: Analysis of variance with Tukey-Kramer post hoc tests examined whether variables differed by SOC. RESULTS: Percentages of parents in the pre-action SOC were 34% (PA), 39% (FV), 42% (SD), 45% (TV), and 63% (FJ). Parental self-efficacy, ladder, and child's behavioral level differed significantly by SOC for each topic area (P < .001). Maintenance SOC was significantly higher than pre-action SOC. CONCLUSIONS AND IMPLICATIONS: Measured variables exhibited a theoretically consistent pattern across SOC, suggesting construct validity and potential usefulness for obesity prevention efforts.

Three stage-based expert system interventions for smoking, high-fat diet, and unsafe sun exposure were evaluated in a sample of 2,460 parents of teenagers. Eighty-four percent of the eligible parents were enrolled in a 2-arm randomized control trial, with the treatment group receiving individualized feedback reports for each of their relevant behaviors at 0, 6, and 12 months as well as a multiple behavior manual. At 24 months, the expert system outperformed the comparison condition across all 3 risk behaviors, resulting in 22% of the participants in action or maintenance for smoking (vs. 16% for the comparison condition), 34% for diet (vs. 26%), and 30% for sun exposure (vs. 22%). Proactive, home-based, and stage-matched expert systems can produce significant multiple behavior changes in at-risk populations where the majority of participants are not prepared to change.

OBJECTIVE: Few studies have compared similar alcohol-related constructs such as alcohol expectancies and decisional balance: two conceptualizations of the positive and negative aspects of alcohol. The purpose of this study was to compare these constructs and to examine their ability to predict alcohol use and problems. METHOD: A sample of 406 college students recruited from Psychology courses at a mid-sized Northeastern University completed a questionnaire that included measures of alcohol expectancies, decisional balance, drinking indices and drinking problems. Of these students, N = 389 (73% female) were drinkers and were included in analyses. RESULTS: Positive expectancies (PE) and the pros were more related to one another than were negative expectancies (NE) and the cons. The 8-item pros scale outperformed 20 items measuring PE in the prediction of alcohol problems and performed equally well in the prediction of alcohol indices. The negative relationship of cons to alcohol indices, something not found with NE, suggested that the cons scale may include components important to the measurement of negative aspects of alcohol. CONCLUSIONS: Although expectancies, particularly PE, have been a common choice for use by researchers, these data suggest that decisional balance scales may be a better choice because their predictive ability is equal to or better than that of expectancies, and their response burden on participants is lower. Instruments that aim to measure the negative aspects of alcohol use should include severe and distal items to better capture this negative attitudinal domain.

OBJECTIVE: Using a randomized factorial design, we examined the efficacy of a brief motivational intervention (BMI) and a parent-based intervention (PBI) as universal preventive interventions to reduce alcohol use among incoming college students. METHOD: Participants (N = 1,014) were assessed prior to matriculation and at 10 months and 22 months postbaseline. Two-part latent growth modeling was used to simultaneously examine initiation and growth in heavy episodic drinking and alcohol-related consequences. RESULTS: This study retained 90.8% (n = 921) of randomized students at the 10-month follow-up and 84.0% (n = 852) of randomized students at the 22-month follow-up. BMI participants were significantly less likely than non-BMI participants to initiate heavy episodic drinking and to begin experiencing alcohol-related consequences. Effect sizes were minimal at 10 months (Cohen's h ranged from 0.02 to 0.07) and were small at 22 months (hs ranged from 0.15 to 0.22). A significant BMI x PBI interaction revealed that students receiving both the BMI and the PBI were significantly less likely to report the onset of consequences beyond the sum of the individual intervention effects (h = 0.08 at 10 months, and h = 0.21 at 22 months). Hypothesized direct BMI effects for reductions in heavy episodic drinking and consequences were not observed. Significant mediated effects via changes in descriptive norms were present for both growth and initiation of heavy episodic drinking and consequences. CONCLUSIONS: To our knowledge, the current study is the first to provide support for BMI as a universal preventive intervention for incoming college students. Although hypothesized PBI main effects were not found, mediation analyses suggest future refinements could enhance PBI effectiveness.

BACKGROUND: Treating multiple health behavior risks on a population basis is one of the most promising approaches to enhancing health and reducing health care costs. Previous research demonstrated the efficacy of expert system interventions for three behaviors in a population of parents. The interventions provide individualized feedback that guides participants through the stages of change for each of their risk behaviors. This study extended that research to a more representative population of patients from primary care practice and to targeting of four rather than three behaviors. METHODS: Stage-based expert systems were applied to reduce smoking, improve diet, decrease sun exposure, and prevent relapse from regular mammography. A randomized clinical controlled trial recruited 69.2% of primary care patients (N = 5407) at home via telephone. Three intervention contacts were delivered for each risk factor at 0, 6, and 12 months. The primary outcome measures were the percentages of at-risk patients at baseline who progressed to the action or maintenance stages at 24-month follow-up for each of the risk behaviors. RESULTS: Significant treatment effects were found for each of the four behaviors, with 25.4% of intervention patients in action or maintenance for smoking, 28.8% for diet, and 23.4% for sun exposure. The treatment group had less relapse from regular mammography than the control group (6% vs. 10%). CONCLUSION: Proactive, home-based, and stage-matched expert systems can produce relatively high population impacts on multiple behavior risks for cancer and other chronic diseases.

OBJECTIVE: The impact of worksite intervention studies is maximized when reach and enrollment are high and attrition is low. Differences in reach, enrollment, and retention were investigated by comparing 2 different employee recruitment methods for a home-based cancer-prevention intervention study. METHODS: Twenty-two worksites (N = 10,014 employees) chose either active or passive methods to recruit employees into a home-based intervention study. Reach (e.g., number of employees who gave permission to be called at home), Enrollment (e.g., number of employees who joined the home intervention study), and Attrition (e.g., number who did not complete the 12- and 24-month follow-ups) were determined. Analysis at the cluster level assessed differences between worksites that selected active (n = 12) versus passive (n = 10) recruitment methods on key outcomes of interest. Employees recruited by passive methods had significantly higher reach (74.5% vs. 24.4% for active) but significantly lower enrollment (41% vs. 78%) and retention (54% vs. 70%) rates (all ps < .0001). Passive methods also successfully enrolled a more diverse, high-risk employee sample. Passive (vs. active) recruitment methods hold advantages for increased reach and the ability to retain a more representative employee sample. Implications of these results for the design of future worksite studies that involve multilevel recruitment methods are discussed.
