ABSTRACT
OBJECTIVES: Increases in electronic media communication (EMC) and decreases in face-to-face peer contact in the evening (FTF) have been thought to explain the recent decline in adolescent substance use (alcohol, tobacco, cannabis). This study addresses this hypothesis, by examining associations between (time trends in) EMC, FTF, and substance use in more than 25 mainly European countries. METHODS: Using 2002-2014 data from the international Health Behaviour in School-aged Children (HBSC) study, we ran multilevel logistic regression analyses to investigate the above associations. RESULTS: National declines in substance use were associated with declines in FTF, but not with increases in EMC. At the individual level, both EMC and FTF related positively to substance use. For alcohol and cannabis use, the positive association with EMC was stronger in more recent years. Associations between EMC and substance use varied across countries, but this variation could not be explained by the proportion of young people using EMC within countries. CONCLUSIONS: Our research suggests that the decrease in FTF, but not the increase in EMC, plays a role in the recent decrease in adolescent substance use.

The present study aimed to develop a short, easily administered, psychometrically sound, and valid instrument to assess the severity of compulsive Internet use. A set of criteria was determined based on the addiction literature. Next, the internal consistency and convergent validity were determined, and the set was tested as a one-factor solution in two representative samples of heavy Internet users (n = 447 and n = 229) and in one large convenience sample of regular Internet users (n = 16,925). In these three studies, respondents were asked about their online behavior and about problems related to Internet use. In the first study, the Online Cognition Scale (OCS) was included to determine concurrent validity. The newly developed Compulsive Internet Use Scale (CIUS) contains 14 items ratable on a 5-point Likert scale. The instrument showed good factorial stability across time and across different samples and subsamples. The internal consistency is high, and high correlations with concurrent and criterion variables demonstrate good validity.

This prospective population-based study aimed to compare associations between depressive feelings and smoking behaviour of adolescents with and without asthma. Data were collected from a two-wave 22-24 months prospective study among 5938 adolescents who completed self-report questionnaires. Logistic regression analyses showed that depressive feelings and smoking were related both cross-sectionally and longitudinally. Smoking behaviour was similar for adolescents with and without asthma, as well as its correlation with depressive feelings. However, participants with asthma were more likely to report depressive feelings than those without asthma, implying an indirect relationship between asthma and smoking behaviour. Implications for prevention are addressed.

AIM: The aim of this study was to examine the development of alcohol consumption and 'binge drinking' in The Netherlands over the period 1997-2005. METHODS: Data from three national population surveys commissioned by the Dutch Ministry of Health were compared. RESULTS: Decreases in binge drinking have appeared, especially for youngsters, which are not explained by changes in the composition of the population according to religious orientation, and for which no other explanation can be given at present. CONCLUSION: Trends in binge drinking in The Netherlands can vary over relatively short spaces of time.
