The first part of this thesis therefore focusses on the lowest end of the psychosis continuum:
PLEs and subclinical psychotic symptoms reported by individuals of the general
population and unaffected first-degree relatives of psychosis spectrum patients. As these
can be assessed through measures of (‘subjective’) self-report and (‘objective’) clinical
interviews, the studies in this first part focus on the distinction between self-reported
psychotic experiences versus ‘clinically validated’ psychotic symptoms.
