Description
Summary:Aim Valid instruments for the early identification of psychotic experiences (PE) and symptoms in youths are urgently needed for large‐scale preventive interventions. A new section of The‐Development‐and‐Well‐Being Assessment (DAWBA) measuring child self‐reported PE has yet to be validated. The current study aimed to investigate the concurrent validity of DAWBA‐based self‐reported PE (PE‐S) with regard to interview‐based measures of PE (PE‐I). Methods Participants were 1571 (47.8% male) children of age 11 to 12 years from the Copenhagen Child Cohort 2000 (CCC2000) with complete data from both the online PE‐section of DAWBA and the following face‐to‐face interview and assessment of PE. The DAWBA‐PE‐section asks the child 10 questions covering auditory and visual hallucinations, delusional ideas and subjective thought disturbances ever in life; and attributions to sleep, fever, illness or drug intake. The interview‐based assessment of PE was performed by trained professionals using 22 items from The Schedule for Affective Disorders and Schizophrenia for School Aged Children‐Present and Lifetime Version (KSADS‐PL). The two assessments were completed independently. Results The prevalence of PE‐S was 28.1% (24.3% for PE‐S with no frequent attributions), compared with 10.2% for PE‐I. The predictive values of PE‐S for any PE‐I were: sensitivity = 73.8%, specificity = 77.1%, positive predictive value (PPV) = 26.8% and negative predictive value (NPV) = 96.3%. Self‐reported visual hallucinations had the best overall predictive values with a sensitivity of 43.1%, specificity of 94.0%, PPV of 44.8% and a NPV of 93.6% for any PE‐I. Conclusion The DAWBA‐section proved valuable as a screening tool for PE in the youth general population.
