21.L. Workshop: To what extent can we trust our data on trends in mental health among adolescents?

Abstract

Abstract Mental health complaints have increased among school-aged children in the Nordic countries, especially among girls according to survey data in the Nordic countries. Moreover, the consumption of mental health services among adolescents has also increased. However, criticism from qualitative researchers have questioned the validity of the response to survey questions and the interpretation of the results. This controversy has been public in the media both in Denmark and Sweden. The objectives of the workshop are to describe trends in mental health among adolescents in the Nordic countries, review criticism of mental health indicators, discuss measurement and analytical options, and consider consequences for policy making. Moreover, the workshop will discuss the situation in other parts of the worlds. Researchers in five Nordic countries have collaborated in the Health Behaviour of School-aged Children (HBSC) study to mental health. School-aged children, 11-, 13- and 15-year olds (n = 112,000) have participated in HBSC surveys. Of key concern are psychosomatic complaints (1985-2018), but trends will also be presented for indicators of excellent self-rated health and high life satisfaction (2002-2018), with additional indicators of positive mental health (Warwick Edinburgh Mental Well-being Scale, General self-efficacy, Self-esteem) from the 2017/18 HBSC data collection. There has been an increase in the psychosomatic complaints among girls and boys, in all age groups and in the five Nordic countries. Strengths and limitations of epidemiological surveys will be discussed. The impact of different frequency cut points will be presented as well as the heterogeneities regarding profiles of adolescents with different combination of negative and positive mental health indicators. Moreover, qualitative studies and registry-based analysis will be used as contrasting evidence. The qualitative studies on symptom perception indicate that the prevalence of problems may be overestimated, and data from psychiatric care and prescription of drugs show important increase. After an introduction and two presentations the workshop will be a dialogue with the participants. First the core similarities and differences between countries will be explored. Then the policy implications will be discussed. Key messages The HBSC survey design give thousands of adolescents and children across dozens of nations the ability to be heard through a reliable and valid methodology. It is important to use indicators according to their intended use, monitoring of population trends, developing causal networks of determinants, screening of clinical cases or as diagnostic tools.
