The Behavior and Mind Health (bemind) Study: Methods, Design and Baseline Sample Characteristics of a Cohort Study among Adolescents and Young Adults.

OBJECTIVES:The Behavior and Mind Health (BeMIND) study is a population-based cohort study of adolescents and young adults from Dresden, Germany. The aim is to investigate psychological and behavioral factors linked to a range of mental disorders and health behaviors and their interaction with social-environmental and genetic/biologic factors.METHODS:A random sample of 14-21 year olds was drawn from the population registry in 2015. The baseline investigation was completed 11/2015-12/2016 (N = 1,180). Assessments include standardized diagnostic interview, cognitive-affective tasks, questionnaires, biosamples, and ecologic momentary assessment in real life with combined actigraphic/geographic monitoring. In the family study component, parents completed similar assessments and provided information on child's early development.RESULTS:The participation rate (minimum response proportion) was 21.7%; the cooperation rate was 43.4%. Acceptance and completion of study components were high. General health data indicate that more than 80% reported no or only mild impairment due to mental or somatic health problems in the past year; about 20% ever sought treatment for mental health problems or chronic somatic illnesses, respectively.CONCLUSIONS:Data from BeMIND baseline and follow-up investigations will provide novel insights into contributors to health and disease as adolescents grow into adulthood.
