COMPLETE - a school-based intervention project to increase completion of upper secondary school in Norway: study protocol for a cluster randomized controlled trial.

BACKGROUND: Drop out from upper secondary school represents a risk for the future health and wellbeing of young people. Strengthening of psychosocial aspects of the learning environment may be an effective strategy to promote completion of upper secondary school. This paper is a study protocol of a school based cluster randomized controlled trial (RCT) evaluating two school-based interventions, namely the Dream School Program (DSP) and the Mental Health Support Team (MHST). The interventions aim to improve psychosocial learning environments and subsequently school achievements and decrease drop-out and absence. METHODS/DESIGN: The COMPLETE RCT is aimed at youth in upper secondary school, grade 1 (age 15-16 years), and examines the effect of the combination of the DSP and the MHST; and the DSP only, compared with a comparison group on the following primary outcomes: student completion, presence, average grade, and self-reported mental health. Seventeen upper secondary schools from four counties in Norway were randomized to one of the three arms: 1) DSP and MHST; 2) DSP; and 3) comparison (offered DSP intervention in 2018/2019). The study will evaluate the interventions based on information from two cohorts of students (cohort 1 (C1) and cohort 2 (C2)). For C1, data was collected at baseline (August 2016), and at first follow-up seven months later. Second follow-up will be collected 19 months after baseline. For C2, data was collected at baseline (August 2017), and first and second follow-up will be collected similarly to that of C2 seven and 19 months respectively after baseline. Process evaluations based on focus groups, interviews and observation will be conducted twice (first completed spring 2017). DISCUSSION: The COMPLETE trial is a large study that can provide useful knowledge about what interventions might effectively improve completion of upper secondary school. Its thorough process evaluation will provide critical information about barriers and points of improvement for optimizing intervention implementation. Findings can guide school development in the perspective of improving psychosocial learning environments and subsequent completion of upper secondary schooling. TRIAL REGISTRATION: The trial was retrospectively registered in the ClinicalTrials.gov register on December 22.2017: NCT03382080 .

The Relationship between Body Image and Depressed Mood in Adolescence: A 5-year Longitudinal Panel Study.

Much research interest has been devoted to reveal the psychosocial processes associated with the development of depressive symptoms during adolescence. One of the important factors that has been studied is body image. In a 5-year longitudinal investigation, we revealed and discussed the relationship between body image and depressed mood in a cohort of adolescents at ages 13, 15 and 18. Girls reported on average higher depressed mood levels and more negative body image than boys at all ages. However, the correlations between the variables were nearly as strong for boys as for girls. Structural equation modelling revealed that body image predicted change in depressed mood both for boys and girls, but at different ages. In contrast, we did not find any support for the existence of causal effects of depressed mood upon body image.
