“…4.68 vs 3.47 PLEs) was found in total. Specific diagnoses were not significantly linked to a higher number of PLEs .This supports earlier findings in literature [3,26] i.e. that the presence of PLEs is prevalent in a higher rate in a population that is confronted with more difficulties and stress, without being predictive for a diagnosis for any specific diagnosisd especially not being predictive for the presence of a psychotic disorder.…”

Objective: Psychotic like experiences (PLEs) resemble psychotic symptoms but are more benign and transient. They occur numerously in clinical and non-clinical samples and have a peak incidence in adolescence. PLEs can be linked to psychopathology and, in the presence of risk factors, PLEs can make a transition to psychotic symptoms and psychosis. The aim of this study was to measure the occurrence of PLEs in a Flemish clinical sample of adolescents using the CAPE (Community Assessment of Psychic Experiences). Gender, age, IQ differences and possible links with psychopathology, distress and impairment have been investigated.Method: 1176 adolescents between 12 and 17 years old were referred to a child and adolescent psychiatric outpatient clinic for psychiatric assessment. PLEs were measured using the CAPE, more precisely the CAPE positive experiences scale (CAPE-P, 20 questions). PLEs were divided into 5 subdimensions: Hallucination, Paranoia, Delusion, Grandiosity and Paranormal Belief.Results: 734 CAPEs were valid for research. 94.2% of adolescents in the clinical sample reported at least one PLE at least 'sometimes'. 62.3% of our population reported at least one PLE at least 'often', which was a higher rate than found in the general population. 83.2% of the population reported at least 'a bit distress' for at least one PLE, whereas 51% reported to be 'quite or very distressed' about at least one PLE. Girls reported more PLEs than boys and reported higher levels of distress. There was no significant general trend in PLEs found when looked at age or IQ distribution. PLEs with distress could be linked to psychopathology in general, but not to specific diagnoses. Conclusion:In comparison to the general population, adolescents in a clinical population experience PLEs more often and with a higher degree of distress. The CAPE can be used in a clinical population for follow up and identification in the risk of transition. Higher risk can be defined by a higher score of frequency and distress on the CAPE and the persistence of this score over time. Risk of transition increases with a certain degree of impairment (that might be caused by comorbid psychopathology) and the combination with specific risk factors for psychosis.

“…An increased association between APS and psychiatric morbidity across adolescence as suggested by Kelleher et al (2012b) was not confirmed (Schimmelmann et al, 2015). A higher prevalence of the self-reported factor 'Perceptual Abnormalities' in 11-12-year-olds compared to 17-18-year-olds and lack of an association between self-reported attenuated psychotic-like experiences and psychiatric morbidity was also reported from a help-seeking CAD sample (Brandizzi et al, 2014).…”

Objective: The validity of current ultra-high risk (UHR) criteria is under-examined in help-seeking minors, particularly, in children below the age of 12 years. Thus, the present study investigated predictors of one-year outcome in children and adolescents (CAD) with UHR status.Method: Thirty-five children and adolescents (age 9-17 years) meeting UHR criteria according to the Structured Interview for Psychosis-Risk Syndromes were followed-up for 12 months.Regression analyses were employed to detect baseline predictors of conversion to psychosis and of outcome of non-converters (remission and persistence of UHR versus conversion).

Early detection of psychosis is an important topic in psychiatry. Yet, there is limited information on the prevalence and clinical significance of highrisk symptoms in children and adolescents as compared to adults. We examined ultra-high-risk (UHR) symptoms and criteria in a sample of individuals aged 8-40 years from the general population of Canton Bern, Switzerland, enrolled from June 2011 to May 2014. The current presence of attenuated psychotic symptoms (APS) and brief intermittent psychotic symptoms (BLIPS) and the fulfillment of onset/worsening and frequency requirements for these symptoms in UHR criteria were assessed using the Structured Interview for Psychosis Risk Syndromes. Additionally, perceptive and non-perceptive APS were differentiated. Psychosocial functioning and current non-psychotic DSM-IV axis I disorders were also surveyed. Welltrained psychologists performed assessments. Altogether, 9.9% of subjects reported APS and none BLIPS, and 1.3% met all the UHR requirements for APS. APS were related to more current axis I disorders and impaired psychosocial functioning, indicating some clinical significance. A strong age effect was detected around age 16: compared to older individuals, 8-15-year olds reported more perceptive APS, that is, unusual perceptual experiences and attenuated hallucinations. Perceptive APS were generally less related to functional impairment, regardless of age. Conversely, non-perceptive APS were related to low functioning, although this relationship was weaker in those below age 16. Future studies should address the differential effects of perceptive and non-perceptive APS, and their interaction with age, also in terms of conversion to psychosis.
