Sleep Duration and Quality in Adolescents
INTRODUCTION: Inadequate sleep duration and sleep-related problems are highly prevalent among adolescents and pose a significant health risk during a critical development stage. This study seeks to explore associations between sleep and suicidal ideation among adolescents. METHODS: Cross-sectional questionnaire data from the baseline wave (2016-2018) of a cohort of 12- to 16-year-old Swedish adolescents (n = 4433, 50.39% girls) were analyzed. A s…
Adolescents’ screen time displaces multiple sleep pathways and elevates depressive symptoms over twelve months
Recently the Swedish Public Health Agency published recommendations of a maximum of two-to-three hours of daily leisure screen time for adolescents aged 13–18, partly to promote better sleep (2024-Sep-02). Biologically and socially, adolescence is characterized by belated sleep times, and depressive effects of screen time can arise through sleep displacements. Theorized links between screen time, sleep, and depression, merited examination of four…
Longitudinal Effects of Screen Time on Depressive Symptoms among Swedish Adolescents
Studies suggest that hourly digital screen time increases adolescents' depressive symptoms and emotional regulation difficulties. However, causal mechanisms behind such associations remain unclear. We hypothesized that problem-focused and/or emotion-focused engagement coping moderates and possibly mediates this association over time. Questionnaire data were collected in three waves from a representative sample of Swedish adolescents (0, 3 and 12 …
Measuring Attitudes toward Suicide Prevention among Occupational Staff Frequently Exposed to Suicidal Individuals
As the attitudes of healthcare staff are thought to influence the quality and effectiveness of interventions targeting patients' suicide risk, attitudes are often used as an outcome in the evaluation of suicide-preventive training. Due to various problems related to the validity and reliability of commonly used scales, there is a lack of overall agreement on how to measure these attitudes. Confirmatory factor analysis (CFA) was used to cross-vali…
Decision-Making in Suicidal Behavior
This and previous studies suggest that altered decision-making is involved in suicide attempts. In our study, we show the involvement of loss aversion in particular, and propose that individuals high in loss aversion are discouraged from carrying out the suicide attempt because of a greater focus on the negative consequences of the decision
