STUDY Smart!

The research project STUDY Smart! is a nationwide intervention study on the effects of smartphone breaks in the academic context. Using a longitudinal design, the study examines the effects of planned smartphone breaks during student learning phases on outcome variables such as individual well-being, concentration, and academic performance. Potential moderating influences are also captured. The research project aims to expand the limited research literature on digital detox and smartphone breaks, providing important implications for healthy and successful studying in the smartphone era.

TWOgether

Within the framework of TWOgether, the physical activity of adolescents is intended to be increased. The focus is to examine whether long-term increases in activity are more successful when engaging in physical activity with a friend. The study utilizes diary surveys and activity sensors to ensure the most accurate assessment of physical activity. The adolescents will be followed for a period of six months. Adolescent friends between the ages of 14 and 18 years, who are not sufficiently active according to the official recommendations of the Federal Office of Public Health, Switzerland, will be surveyed.
