Basic self-disturbance in adolescents at risk of psychosis: temporal stability investigated by the experience sampling method in a mixed method study.

ABSTRACT:

Background

Basic self-disturbance (BSD), also called anomalous self-experiences (ASEs), are core phenotypic markers for schizophrenia spectrum disorders and a prepsychotic vulnerability marker considered to be temporally stable (trait-phenomenon). Studies of BSD in children and adolescents are lacking.

Objective

To be clinically useful, we need to know more about the characteristics and temporal development of BSD in prepsychotic phases.

Method

This study used a smartphone application measuring the occurrence and subjective intensity of ASEs in the daily life of 27 help-seeking adolescents (12-18 years) repeatedly over a period of 6 months. A total of 5223 unique application-reports based on individually selected and verbatim descriptions of personal core ASEs were an
