Fear of missing out and binge-drinking among adolescents.

INTRODUCTION: No previous studies have examined the cross-sectional association between fear of missing out (FOMO) and binge-drinking among adolescents. The aim of the present study was: (i) to estimate the magnitude of this association; (ii) to assess the impact of potential confounders (i.e. sensation-seeking, symptoms of depression and self-regulation); and (iii) determine if it is uniform across all levels of these characteristics. METHODS: Cross-sectional study of adolescents from 33 middle schools in Norway, stratified according to geographic location, urban and rural locations, and standard of living. Participants were a nation-wide sample of N = 2646 adolescents (mean age 16.2 years, 43% boys). Self-report data were collected on binge-drinking, FOMO, sensation-seeking, symptoms of depression and self-regulation. RESULTS: Overall, 21% reported binge-drinking ≤ once per month in the past 12 months, while 9% reported binge-drinking more than once per month. Multinomial logistic regression showed that the crude effect, where greater FOMO was associated with greater risk of binge-drinking, was substantial (relative-risk ratio = 1.50 [1.35, 1.66], P < 0.001), but somewhat attenuated after including all potential confounders (relative-risk ratio = 1.28 [1.14, 1.43], P < 0.001). Effect modification analyses showed that the effect of FOMO on binge-drinking ≤ once per month was stronger for adolescents with low symptom levels of depression and weaker for adolescents at high levels of depression. DISCUSSION AND CONCLUSION: Norwegian adolescents with higher FOMO have greater risk of binge-drinking.

Are changes in binge drinking among European adolescents driven by changes in computer gaming?

INTRODUCTION: There is currently no good explanation for the decline in adolescent drinking reported for many Western countries in recent years. As modern computer gaming is highly exciting and socially rewarding, it may function as a substitute for adolescent binge drinking. We hypothesized a negative correlation between country-level changes in computer gaming and binge drinking. METHODS: We analysed within-country changes based on data from 15-16 year-old pupils (n = 517 794) participating in the European School Survey Project on Alcohol and Drugs from 1995 to 2015. Binge drinking in the last 30 days (5+ units on one occasion) was regressed on frequency of computer gaming and three control variables measuring the frequency of engagement in other hobbies, reading books and going out (to a disco, cafe, etc.). RESULTS: Descriptive data showed no general decline in binge drinking across European countries. In contrast to our prediction, the association between binge drinking and computer gaming was not negative [b = 0.26, one-sided 95% confidence interval (-∞, 0.47), P = 0.98, Bayes Factor = 0.21]. We found the same pattern of result in a secondary analysis on six Nordic countries that have experienced declines in adolescent drinking recent years. In analyses with covariates reflecting engagement in other activities, we only observed statistical evidence for an effect of going out. DISCUSSION AND CONCLUSIONS: A substantial decline in adolescent binge drinking during the years 1995-2015 is only evident in some European countries, and it is likely not caused by increased computer gaming.

Why Is Per Capita Consumption Underestimated in Alcohol Surveys? Results from 39 Surveys in 23 European Countries.

AIMS: The aims of the article are (a) to estimate coverage rates (i.e. the proportion of 'real consumption' accounted for by a survey compared with more reliable aggregate consumption data) of the total, the recorded and the beverage-specific annual per capita consumption in 23 European countries, and (b) to investigate differences between regions, and other factors which might be associated with low coverage (prevalence of heavy episodic drinking [HED], survey methodology). METHODS: Survey data were derived from the Standardised European Alcohol Survey and Harmonising Alcohol-related Measures in European Surveys (number of surveys: 39, years of survey: 2008-2015, adults aged 20-64 years). Coverage rates were calculated at the aggregated level by dividing consumption estimates derived from the surveys by alcohol per capita estimates from a recent global modelling study. Fractional response regression models were used to examine the relative importance of the predictors. RESULTS: Large variation in coverage across European countries was observed (average total coverage: 36.5, 95% confidence interval [CI] [33.2; 39.8]), with lowest coverage found for spirits consumption (26.3, 95% CI [21.4; 31.3]). Regarding the second aim, the prevalence of HED was associated with wine- and spirits-specific coverage, explaining 10% in the respective variance. However, neither the consideration of regions nor survey methodology explained much of the variance in coverage estimates, regardless of the scenario. CONCLUSION: The results reiterate that alcohol survey data should not be used to compare or estimate aggregate consumption levels, which may be better reflected by statistics on recorded or total per capita consumption.

Depressive Symptomatology among Norwegian Adolescent Boys and Girls: The Patient Health Questionnaire-9 (PHQ-9) Psychometric Properties and Correlates.

This study explored the potential contribution of the Diagnostic and Statistical Manual for Mental Disorders (DSM-IV)-based Patient Health Questionnaire-9 item (PHQ-9) instrument to the developmental epidemiology research in Norway, by examining depressive symptoms in a school sample of adolescents (N = 846). The average PHQ-9 scores were 6.89 (SD = 5.13) for girls, and 4.57 (SD = 3.98) for boys; 8.5% of girls and 2.6% of boys were classified into the originally proposed categories indicative of Major Depressive Disorder (MDD; PHQ-9 scores ≥ 15). Multi-group confirmatory factor analysis (CFA) confirmed a single-factor structure for the PHQ-9 with solid psychometric properties and high internal consistency for both genders. However, even though configural equality was observed, there was no evidence for metric or scalar equality across genders, warranting further investigation of measurement equivalence for the current Norwegian version of the PHQ-9. We observed no major associations between the PHQ-9 scores and adolescent religion or immigrant background. Further, school grade, not living together with both biological parents, and diagnosed chronic illness were differently associated with elevated depressive symptoms for boys and girls. Finally, high residential instability, perceived low SES, school dissatisfaction, lack of close friendships, history of suicide attempts and self-harm, and elevated emotional problems were all significantly and consistently associated with greater depression for both genders. Overall, the PHQ-9 appears to be a promising research tool, potentially offering clinically-relevant classification of adolescent self-reported depressive symptomatology in addition to the symptom severity captured by continuous scores. Nevertheless, further investigation concerning the observed measurement non-equivalence, as well as the comprehensive validation and comparison against the gold standard is required before the PHQ-9 is to be used for diagnostic screening in Norway.
