Prevalence of prodromal risk syndromes among “non help-seeking” young adolescents in the community: influence of assessment criteria.

Presentation First Author:

There is a lack of knowledge about the prevalence of prodromal risk syndromes in the community, despite the proposal to introduce a new diagnosis of “Attenuated Psychosis Syndrome” into DSM-V. Thus far, research has been conducted only in the context of individuals attending “prodrome” service or clinic. In order to address this issue, we conducted clinical interviews with 212 adolescents recruited from schools in order to assess for psychotic symptoms, prodromal risk syndromes and other psychopathology. We found that between 1.5-8% of this community based sample fulfilled criteria for a prodromal risk syndrome. The rate varied with the assessment criteria used, in particular the measurement of disability. None of these adolescents had sought help for psychotic symptoms. The adolescents who fulfilled criteria for a prodromal risk syndrome had a higher prevalence of other psychopathology and poorer global functioning. They displayed a range of neuropsychological deficits compared with adolescents with no psychotic symptoms and compared with adolescents who reported psychotic symptoms but who did not fulfil criteria for a prodromal risk syndrome. We conclude that further research is needed on prevalence, outcome and co-morbidity among “non help-seeking” individuals who fulfil criteria for prodromal risk syndromes in the community.
