Process evaluation of the Belgian one-month-without alcohol campaign 'Tournée Minérale': a mixed method approach.

BACKGROUND: The Tournée Minérale campaign [TMC] is a mass media prevention campaign challenging Belgian adults to refrain from alcohol during one month. A process evaluation may help us better understand the effect of TMC and to formulate recommendations for future editions. The current study aimed to examine reach, experiences, perceived effectiveness and maintenance of TMC. METHODS: A mixed method design was used to assess the process, using pre- and post-questionnaires (n = 49.022, 44.5 ± 13.1 years old, 37.0% men) and focus groups (n = 31, 47.3 ± 14.3 years old, 33.3% men). RESULTS: Most campaign materials were considered useful and/or motivating. Facilitators for taking part in TMC were connectedness with other participants, stimulus control (e.g. removing alcohol at home) and a supportive social environment. Most difficulties were encountered with abstaining during social occasions as participants had to change a habit or find alternative non-alcoholic beverages. Participants reported both beneficial (e.g. sleeping better) and adverse effects (e.g. drinking more soft drinks). CONCLUSIONS: Future editions of TMC should try to decrease perceived adverse effects (e.g. by providing attractive non-alcoholic beverages) and can benefit from having a forum where people can share experiences.

Problem drinking among Flemish students: beverage type, early drinking onset and negative personal & social consequences.

BACKGROUND: Although alcohol is socially accepted in most Western societies, studies are clear about its associated negative consequences, especially among university and college students. Studies on the relationship between alcohol-related consequences and both beverage type and drinking onset, however, are scarce, especially in a European context. The aim of this research was, therefore, twofold: (1) What is the relationship between beverage type and the negative consequences experienced by students? and (2) Are these consequences determined by early drinking onset? We will examine these questions within the context of a wide range of alcohol-related consequences. METHODS: The analyses are based on data collected by the inter-university project 'Head in the clouds?', measuring alcohol use among students in Flanders (Belgium). In total, a large dataset consisting of information from 19,253 anonymously participating students was available. Negative consequences were measured using a shortened version of the Core Alcohol and Drug Survey (CADS_D). Data were analysed using negative binomial regression. RESULTS: Results vary depending on the type of alcohol-related consequences: Personal negative consequences occur frequently among daily beer drinkers. However, a high rate of social negative consequences was recorded for both daily beer drinkers and daily spirits drinkers. Finally, early drinking onset was significantly associated with both personal and social negative consequences, and this association was especially strong between beer and spirits drinking onset and social negative consequences. CONCLUSIONS: Numerous negative consequences, both personal and social, are related to frequent beer and spirits drinking. Our findings indicate a close association between drinking beer and personal negative consequences as well as between drinking beer and/or spirits and social negative consequences. Similarly, early drinking onset has a major influence on the rates of both personal and social negative consequences. The earlier students started drinking, the more negative consequences they experienced during college or university. Several (policy) interventions are discussed. This study is the first to incorporate detailed information on both beverage type and drinking onset, and its associated negative consequences, as measured by the CADS_D, in a large student population.

The Relationship Between Pain Severity and Alcohol Use Among School-Aged Children and Adolescents: The Moderating Role of Drinking Motives.

Objective: Evidence from adult samples suggests a co-occurrence between pain and alcohol abuse. However, studies in adolescents are scarce and results are inconsistent, with some studies observing heightened and others observing reduced alcohol consumption in adolescents suffering from pain. We hypothesized that in adolescents the association between pain and alcohol use will be moderated by drinking motives. Methods: Data from a large representative sample of Flemish school children and adolescents (N = 10,650, 50.8% boys, age range = 10-21 years, Mage = 14.33 years) were collected as part of the World Health Organization collaborative Health Behaviour in School-Aged Children (HBSC) survey. Pain severity was graded based on a pediatric pain classification system that accounts for both pain intensity and disability. Alcohol consumption was operationalized using two variables: frequency of drinking and drunkenness. The Drinking Motives Questionnaire-Revised was used to capture drinking motives; it assesses four motive categories (enhancement, coping, social, and conformity). Results: Findings indicated that higher pain severity was associated with greater frequency of alcohol use and drunkenness. However, drinking motives moderated this association. The positive association between pain severity and drinking frequency was stronger in case of high conformity motives. Likewise, the association between pain severity and drunkenness frequency was stronger at high levels of conformity motives and reached significance only at high levels of coping motives. Conclusions: Our findings suggest that specific drinking motives are linked to problematic alcohol use in adolescents with pain. Future studies using a longitudinal design are needed to draw conclusions about direction of effects.

The psychometric properties of a shortened Dutch version of the consequences scale used in the Core Alcohol and Drug Survey.

BACKGROUND: Alcohol and drug misuse among college students has been studied extensively and has been clearly identified as a public health problem. Within more general populations alcohol misuse remains one of the leading causes of disease, disability and death worldwide. Conducting research on alcohol misuse requires valid and reliable instruments to measure its consequences. One scale that is often used is the consequences scale in the Core Alcohol and Drug Survey (CADS). However, psychometric studies on the CADS are rare and the ones that do exist report varying results. This article aims to address this imbalance by examining the psychometric properties of a Dutch version of the CADS in a large sample of Flemish university and college students. METHODS: The analyses are based on data collected by the inter-university project 'Head in the clouds', measuring alcohol use among students. In total, 19,253 students participated (22.1% response rate). The CADS scale was measured using 19 consequences, and participants were asked how often they had experienced these on a 6-point scale. Firstly, the factor structure of the CADS was examined. Two models from literature were compared by performing confirmatory factor analyses (CFA) and were adapted if necessary. Secondly, we assessed the composite reliability as well as the convergent, discriminant and concurrent validity. RESULTS: The two-factor model, identifying personal consequences (had a hangover; got nauseated or vomited; missed a class) and social consequences (got into an argument or fight; been criticized by someone I know; done something I later regretted; been hurt or injured) was indicated to be the best model, having both a good model fit and an acceptable composite reliability. In addition, construct validity was evaluated to be acceptable, with good discriminant validity, although the convergent validity of the factor measuring 'social consequences' could be improved. Concurrent validity was evaluated as good. CONCLUSIONS: In deciding which model best represents the data, it is crucial that not only the model fit is evaluated, but the importance of factor reliability and validity issues is also taken into account. The two-factor model, identifying personal consequences and social consequences, was concluded to be the best model. This shortened Dutch version of the CADS (CADS_D) is a useful tool to screen alcohol-related consequences among college students.

Who does not cut down? Comparing characteristics and drinking motives of drinkers and abstainers during the exam periods.

OBJECTIVE: Drinking alcohol during the exams can affect academic performance and future career options, but is rarely investigated. Drinking motives, sociodemographics and personality characteristics are investigated in nonabstainers and weekly drinkers during the exams. PARTICIPANTS: 7,181 Belgian university students who anonymously responded to an email invitation to an online survey. METHODS: Logistic regressions and mixed design analysis of variance on cross-sectional data. RESULTS: One-third of the students continued drinking during the exams, with 40% drinking weekly. Nonabstainers were mainly men, elder, internally motivated when drinking, and housed with parents or independently. Weekly drinkers were similar, except mainly housed in student apartments or independently. Personality characteristics were nonsignificant. All drinking motives were less pronounced during the exams, with smaller differences for internal motives. CONCLUSIONS: Mainly linked to internal drinking motives, drinking during the exams in higher education is underestimated. The characteristics and motives of students doing so can be used in future interventions.

The role of community social capital in the relationship between socioeconomic status and adolescent life satisfaction: mediating or moderating? Evidence from Czech data.

BACKGROUND: The concept of social capital has been extensively used to explain the relationship between socioeconomic status (SES) and adolescent health and well-being. Much less is known about the specific mechanism through which social capital impacts the relationship. This paper investigates whether an individual's perception of community social capital moderates or mediates the association between SES and life satisfaction. METHODS: This study employs cross-sectional data from the 2009-2010 Czech Health Behaviour in School-Aged Children survey: a WHO Collaborative Cross-National Study (HBSC). A sample of 4425 adolescents from the 5th, 7th and 9th grade (94.5% school response rate, 87% student response) was used to perform multilevel analysis. RESULTS: We found that pupils' life satisfaction was positively related to both family affluence and perceived wealth. Moreover, we found the cognitive component of social capital to be positively associated with life satisfaction. Additionally, a significant interaction was found, such that the social gradient in life satisfaction was flattened when pupils reported high levels of perceived community social capital. CONCLUSIONS: The present findings suggest that community social capital acts as an unequal health resource for adolescents, but could potentially represent opportunities for public health policy to close the gap in socioeconomic disparities.

Context matters: Student-perceived binge drinking norms at faculty-level relate to binge drinking behavior in higher education.

BACKGROUND: Binge drinking in higher education is an important problem. To target binge drinking in students it is necessary to study the social context of students. Faculties (i.e., colleges or schools in Northern American education) are social contexts in which students behave, but little is known about how the faculty structure relates to monthly binge drinking. This study investigates the relationship with student-perceived binge drinking norms at faculty-level in addition to known personal determinants. METHODS: Data were collected in 7181 students within 22 faculty-level units, using an anonymous online survey. Multilevel analyses were used to investigate the relationship of both individual-level determinants (e.g., perceived norms, social drinking motives) and student-perceived binge drinking norms at faculty-level on monthly binge drinking. RESULTS: Two-third (62.2%) of the sample were female and the mean age was 21.06 (SD=2.85) years. In males, significant faculty-level variance in monthly binge drinking was found. At faculty-level, only same-sex student-perceived binge drinking norms showed a positive relationship (OR=2.581; 95%CI=[1.023,6.509]). At individual level, both opposite- and same-sex perceived binge drinking norms, and social drinking motives positively related to monthly binge drinking. In females, no significant faculty-level variance was found. Only individual-level determinants positively related to monthly binge drinking. No cross-level interactions were found. CONCLUSION: Besides individual determinants, especially in men, faculties are relevant environmental structures and networks to take into account when targeting binge drinking in higher education.

A comparative study of screening instruments and biomarkers for the detection of cannabis use.

BACKGROUND: The aim of this study was to compare the usefulness of 3 different screening instruments (questionnaires) for the detection of cannabis use (CU) with biological markers in blood and hair. METHODS: Ninety-four students were recruited in October 2013. Participants filled out the Severity of Dependence Scale (SDS), the CAGE-AID ("Cut down Annoyed Guilty Eye-opener"-Adapted to Include Drugs), and ProbCannabis-DT questionnaires concerning their possible CU. Blood and hair samples were taken and analyzed by gas chromatography-mass spectrometry. Logistic regression (Nagelkerke R(2)) and receiver operating characteristic (ROC) curve analyses were performed. THCCOOH (Δ(9)-tetrahydrocannabinoic acid) plasma of ≥5 ng/mL and THC (Δ(9)-tetrahydrocannabinol) hair concentrations of ≥0.1 and ≥0.02 ng/mg were used as the gold standard for CU. The questionnaire results were compared with different concentration ranges for THCCOOH in plasma (<5, 5-75, and >75 ng/mL, indicating the intensity of use) and THC in hair (≥0.02 ng/mg, ≥0.1 ng/mg). RESULTS: The Nagelkerke R(2) for comparing the SDS, CAGE-AID, and ProbCannabis-DT with THCCOOH in plasma was 0.350, 0.489, and 0.335, respectively. The area under the ROC curve (95% confidence interval) was 0.772 (0.662-0.882), 0.797 (0.710-0.884), and 0.769 (0.669-0.870), respectively. Corresponding sensitivity/specificity were 70%/84%, 100%/59%, and 87%/67%, respectively. These values were similar to those compared to a 0.02 ng/mg THC cutoff in hair. CONCLUSIONS: Moderate agreement was found between all questionnaires and biomarkers of CU. The CAGE-AID and probCannabis-DT questionnaires were very sensitive, but less specific. SDS was less sensitive, but more specific.

Tracking and predictors of screen time from early adolescence to early adulthood: a 10-year follow-up study.

PURPOSE: To examine tracking of weekday and weekend screen time (ST; i.e., television [TV] and computer [PC] time) from early adolescence to early adulthood and to identify social ecological predictors of weekday and weekend ST among boys and girls separately. METHODS: Data were retrieved from elementary schools (n = 59) in Flanders (Belgium). At baseline, 1,957 children (age, 9.9 ± .43 years) and one of the parents filled out a questionnaire on sedentary behavior and individual, social, and environmental variables. After a 10-year follow-up period, six hundred fifty-five 20-year-olds (age, 19.9 ± .43 years) filled out an adapted questionnaire on sedentary behavior, of which 593 contained full data at baseline and follow-up. Multiple regressions were performed to examine predictors (baseline) of ST (follow-up), and logistic regressions were used to analyze tracking of ST. RESULTS: For boys, a consistent positive predictor of weekday and weekend TV and PC time at follow-up was ST at baseline (p < .01). For girls, drinking more soda at baseline predicted more weekday and weekend TV and PC time at follow-up (p ≤ .02). Some other individual variables also predicted ST in both boys and girls. Tracking was only found among boys; those exceeding the ST guideline at baseline were three to five times more likely to exceed this guideline at follow-up (p ≤ .001). Tracking was not present among girls. CONCLUSIONS: To minimize TV and PC time during early adulthood, interventions for adolescent boys should focus on minimizing ST. For girls, focus should be on healthy eating. However, more research is warranted to confirm these conclusions.

The influence of parental drinking on offspring's drinking motives and drinking: a mediation analysis on 9 year follow-up data.

BACKGROUND AND AIMS: The influence of parental drinking on offspring's drinking is well-documented. However, longitudinal evidence on the mediating role of drinking motives in this relationship is lacking. This study longitudinally investigates the mediating role of drinking motives in the relationship between parental and offspring's drinking. METHODS: Using a prospective design, 587 Flemish children (response 30.0%) were followed for 9 years. Parental drinking was documented during the offspring's late childhood (10 and 11 years old) through paper-and-pencil questionnaires distributed by schools. The offspring's drinking habits and -motives were documented in early adulthood (18 and 19 year old) through a web-based questionnaire; invitations were sent by letter. Motives were measured using the Drinking Motives Questionnaire Revised Short-form, and mediation analyses were conducted with the product of coefficient test using bootstrapping. RESULTS: Half the offspring were female (53.8%) and the mean age was 19.35 (SD = 0.52) years. A significant direct effect of maternal drinking during childhood on offspring drinking nine years later was found (ß = 0.091, t = 2.071, p = 0.039). However, the association turned non-significant after stratifying the model for boys and girls. No direct effect was found for paternal drinking on offspring's drinking. Nevertheless, paternal drinking indirectly affected offspring's drinking through offspring's enhancement motives (ß = 0.041, 95%CI[0.004, 0.082]) and maternal drinking indirectly affected male offspring's drinking through offspring's social motives (ß = 0.067, 95%CI[0.007, 0.148]). CONCLUSION: These results show that parental drinking during late childhood relates to a high level of those drinking motives among young adults that are known risk factors for heavy drinking in early adulthood.
