Research has consistently shown that psychotic experiences lie on a continuum ranging from subclinical symptoms in the general population to clinical symptoms in patient populations (Mcgorry, Nelson, Clin, Goldstone, & Yung, 2010). Early expression of psychotic experiences are common in the general population and often temporary (Linscott & van Os, 2013). In conjunction with certain factors, psychotic experiences may become prolonged and aggravated, increasing the chance of progression into clinical status and requiring care (van Os, Linscott, Myin-Germeys, Delespaul, & Krabbendam, 2009). The aim of the current project is to investigate the role of social factors (social cognition and functioning) in the development of psychotic symptoms in both healthy adolescents, and adolescents and young adults at risk of developing a psychotic disorder. We hypothesize that in healthy adolescents poorer social cognition is associated with poorer social functioning (maladaptive interactions and less social support), which will increase liability for psychotic experiences. We expect to find evidence for this association in both healthy adolescents and in adolescents and young adults currently in the UHR phase. As such, we wish to examine whether these social factors can lead to an improved prediction of transition in UHR samples.. This project comprises a series of four studies: two using existing data from large prospective longitudinal trials and two using a new prospective cohort, with an innovative approach combining experience-sampling monitoring with network analysis, allowing for in-depth analyses of day-to-day interactions and psychotic experiences.
