  • Effectiveness of a Digital Health Game Intervention on Early Adolescent Smoking Refusal Self-Efficacy

    Open Access•Johanna Nyman, Sanna Salantera et al.•ARTICLE•Health Education & Behavior•2024

    Smoking poses a significant threat to adolescent health because of its immediate and long-term detrimental health effects. Smoking refusal self-efficacy predicts smoking behavior in adolescence. In adolescents’ health education, digital interventions are potential tools to support smoking refusal self-efficacy. The aim of this two-arm cluster randomized controlled trial was to evaluate the effectiveness of a digital health game intervention compa…

  • Finnish adolescents’ self-efficacy in peer interactions

    Open Access•Johanna Nyman, Heidi Parisod et al.•ARTICLE•Health Promotion International•2019

    Peers play a significant role in influencing adolescent self-efficacy. Self-efficacy, in turn, has been considered to influence health behavior. The purpose of this qualitative descriptive study was to describe adolescents’ perceptions about their self-efficacy in peer interactions to strengthen the theoretical understanding about the sources of self-efficacy during adolescence. The sample comprised of 155 adolescents (13 − 17 years) in three upp…

  • Spatial variation and seasonal dynamics of leaf-area index in the arctic tundra-implications for linking ground observations and satellite images

    Open Access•Sari Juutinen, Tarmo Virtanen et al.•ARTICLE•Environmental Research Letters•2017

    Vegetation in the arctic tundra typically consists of a small-scale mosaic of plant communities, with species differing in growth forms, seasonality, and biogeochemical properties. Characterization of this variation is essential for understanding and modeling the functioning of the arctic tundra in global carbon cycling, as well as for evaluating the resolution requirements for remote sensing. Our objective was to quantify the seasonal developmen…
