The study aims to explore the effects of hormonal fluctuations throughout the menstrual cycle on social media use, brain architecture, neural reward processing and reward behavior, and affective status in adolescent girls. Additionally, it strives to compare the effects of exogenous and endogenous hormones on the above-mentioned aspects. For this purpose, the investigators will compare two main groups in the study: 1. Naturally cycling adolescent girls, 2. Adolescent girls using combined oral contraceptives. This study will combine self-report data via questionnaires, ecological data via Ecological Momentary Assessment (EMA), endocrine data via blood collection, and neural data via fMRI assessment to enhance the understanding of the neurobiological mechanisms underlying social media use in adolescent girls. Furthermore, it seeks to elucidate whether there are vulnerable periods throughout the menstrual cycle when adolescent girls are especially prone to dysfunctional social media use and help to design more specific interventions as well as therapy.
