Stress and adolescent well-being: the need for an interdisciplinary framework.

Stress and strain among adolescents have been investigated and discussed largely within three separate disciplines: mental health, where the focus has been on the negative effects of stress on emotional health; criminology, where the emphasis has been on the effects of strain on delinquency; and biology, where the focus has been to understand the effects of stress on physiology. Recently, scholars have called for increased multilevel developmental analyses of the bio-psychosocial nature of risk and protection for behaviors of individuals. This paper draws on several different but converging theoretical perspectives in an attempt to provide an overview of research relevant to stress in adolescence and puts forth a new framework that aims to provide both a common language and consilience by which future research can analyze the effects of multiple biological, social and environmental factors experienced during specific developmental periods, and cumulatively over time, on harmful behavior during adolescence.

Population trends in smoking, alcohol use and primary prevention variables among adolescents in Iceland, 1997-2014.

Aims: To estimate linear time-trends in substance use and primary prevention variables in adolescents in Iceland from 1997 to 2014.

Design: Repeated, cross-sectional population-based school surveys with seven waves of pooled data.

Setting: Iceland.

Community social structure, social capital and adolescent smoking: a multi-level analysis.

Using a sample of 6818 individuals in 83 public school districts in Iceland, this study explored the influence of three community characteristics: Residential mobility, proportion of single-parent families, and poverty on adolescent daily smoking. Building on Coleman's social capital theory, we also examined the mediating and moderating role of several measures of social capital. Both self-reported and official data were used to measure key variables.

Bring in the social context: towards an integrated approach to health promotion and prevention.

Aims: In this paper I take up the quest for an integrated approach to health promotion and prevention that incorporates the social context. I suggest that an integrated theory of public health has to rethink the individual society relationships and move beyond the dominance of socialization theory and individual level analysis.

Methods: A theoretical analysis of key issues in an integrated theory of public health.

Sport, and use of anabolic androgenic steroids among Icelandic high school students: a critical test of three perspectives.

Background: This study investigates the use of anabolic androgenic steroids (AAS) among a national representative sample of high school students in Iceland. We test several hypotheses drawn from three perspectives. The first perspective focuses on the use of AAS as an individual phenomenon motivated by the desire to succeed in sport.

The neighborhood effects of disrupted family processes on adolescent substance use.

In the current paper, we argue that the neighborhood-level of disrupted family processes (weak social ties to parents and coercive family interaction) should have a contextual effect on adolescent substance use (cigarette smoking, heavy drinking, and lifetime cannabis use), because adolescents living in neighborhoods in which disrupted family processes are prevalent should be more likely to associate with deviant (substance using) peers. We use nested data on 5491 Icelandic adolescents aged 15 and 16 years in 83 neighborhoods to examine the neighborhood-contextual effects of disrupted family processes on adolescent substance use (cigarette smoking, heavy drinking, and lifetime cannabis use), that is, whether neighborhoods in which disrupted family processes are common have more adolescent substance use, even after partialling out the individual-level effects of disrupted family processes on substance use. As predicted, we find that the neighborhood-levels of disrupted family processes have significant, contextual effects on all the indicators of substance use, and that association with substance using peers mediates a part of these contextual effects.

Substance use prevention for adolescents: the Icelandic Model.

Data from the European School Survey Project on Alcohol and other Drugs have shown that adolescent substance use is a growing problem in western and particularly Eastern European countries. This paper describes the development, implementation and results of the Icelandic Model of Adolescent Substance Use Prevention. The Icelandic Model is a theoretically grounded, evidence-based approach to community adolescent substance use prevention that has grown out of collaboration between policy makers, behavioural scientists, field-based practitioners and community residents in Iceland.

Trends in prevalence of substance use among Icelandic adolescents, 1995-2006.

Background: Adolescent substance use continues to be of great global public health concern in many countries with advanced economies. Previous research has shown that substance use among 15-16 year-old-youth has increased in many European countries in recent years. The aim of this study was to examine trends in prevalence of daily smoking, alcohol intoxication, and illicit substance use among Icelandic adolescents.

Peer groups and substance use: examining the direct and interactive effect of leisure activity.

This paper explores the relationships among adolescent leisure activities, peer behavior, and substance use. We suggest that peer group interaction can have a differential effect on adolescent deviant behavior depending on the type of leisure pattern adolescents engage in. We analyze data from a representative national sample of Icelandic adolescents, exploring the variations in the use of alcohol and illegal drugs among three different patterns of leisure activity, controlling for parental ties and school commitment.
