The dataset.xlsx contains data for my thesis. In the current case-control study, 200 participants (100 with and without PEs) were recruited from the HK-YES cohort, a population-based epidemiological survey examining mental health condition in 3600 community-dwelling Chinese youths aged 15-24 years in Hong Kong. In this thesis, a comprehensive study encompassing psychopathological, standard and hypothesis-driven cognitive functions, and multi-modal magnetic resonance imaging (MRI) measurement is conducted.
