“…The very good interrater and prognostic reliability of these criteria have been established in our previous studies. 35,36 Inclusion thus required 1 or more of the following: attenuated psychotic symptoms, brief limited intermittent psychotic symptoms (BLIPS), or a first-degree relative with a psychotic disorder plus at least 2 indicators of a clinical change, such as a marked decline in social or occupational functioning. Inclusion because of attenuated psychotic symptoms required scores of 2 or 3 on the hallucination item and scores of 3 or 4 on the unusual thought content or suspiciousness items of the BPRS for at least several times a week and persisting for more than 1 week.…”

“…1). For screening and assessment of the at-risk mental state, the Basel Screening Instrument for Psychosis (BSIP) was used [40]. Individuals were assessed and classified as ARMS, FE patients or ''not at risk for psychosis'' (other psychiatric diseases) [37][38][39].…”

Purpose Delay in the treatment of a first psychotic episode can have a negative influence on the future course of the disease. In this context, it is important to examine pathways to care to understand factors contributing to delay in access to adequate care. Methods Using the Basel Interview for Psychosis, we examined the help-seeking behaviour of 61 individuals with an at-risk mental state for psychosis and 37 patients with a first episode of psychosis in a low threshold health care system as part of the Basel early detection of psychosis study. Results The median duration of untreated illness was 3.4 years, of untreated psychosis 12 months. Eighty-six percent of all individuals sought help of some kind before reaching our specialised early detection outpatient clinic, with a mean number of help-seeking contacts of 1.5 prior to referral. The most frequent first help-seeking contacts were family members or relatives n = 24 (26.7 %), close friends n = 17 (17.9 %), psychiatrists in private practice n = 13 (14.4 %) or general practitioners n = 11 (12.2 %). Most patients consulted other health professionals in the early course of the illness before reaching our specialised service; help-seeking with non-medical institutions was rare. Women had more help-seeking contacts than men before contact with our early detection clinic. Conclusions Family, close friends and medical professionals play an important role in help-seeking leading to specialised psychiatric care. Men seek help less often; specific strategies for encouraging young, at-risk men to seek help should be developed.

“…The referrals with suspected psychosis came mainly from general practitioners, psychiatrists in private practices, and from our Psychiatric Outpatient Department. The screening procedure using the Basel Screening Instrument for Psychosis [16] was based on the most important risk factors for and potential indicators of beginning schizophrenia (e.g. genetic risk, psychopathological and psychosocial changes).…”

“…Subjects were included as at risk if they fulfilled the following criteria. Criteria 1.1-''Attenuated psychotic symptoms'' (scores of 2 or 3 on the hallucination item, 3 or 4 on the ''unusual thought content'' or ''suspiciousness'' items of the BPRS for at least several times a week and persisting for more than 1 week) or Criteria 1.2-''Brief Limited Intermittent Psychotic Symptoms'' (BLIPS-scores of 4 or above on the ''hallucinations'' item, or 5 or above on the ''unusual thought content'', ''suspiciousness'' or ''conceptual disorganization'' items of the BPRS, with each symptom lasting less than 1 week before resolving spontaneously) or Criteria 2-genetic risk and at least two further risk factors according to the screening instrument, such as social decline or prodromal symptoms or Criteria 3-a minimal amount and combination of unspecific risk factors according to the BSIP [16].…”

j Abstract Objective EEG investigation in patients with an at risk mental state (ARMS) for psychosis and patients with a first episode of psychosis (FE) in comparison to healthy controls (HC) in a clinical follow up study of Early Detection of Psychosis. Method Seventy-three patients (42 ARMS, 31 FE) and 35 HC were investigated. ARMS patients were followed up in order to monitor transition to psychosis. Psychopathology was assessed with respect to positive and negative symptoms. At study baseline EEG was recorded using the 10/20 system. Two blinded neurologists analyzed the EEGs visually for presence of generalized or focal slowing and epileptiform discharges. EEG data were controlled for medication and substance abuse. For statistical analyses we used v 2 -tests, logistic regression, ANOVA, and receiver operating characteristics. Results Patients showed significantly more pathological EEG abnormalities than HC (P < 0.05), located more frequently in temporal or fronto-temporal regions (P < 0.01) of the brain, with twice as many pathologies in ARMS than in FE patients. The specificity of the prediction of psychosis could be increased from 59 to 73% by considering EEG pathology in addition to psychopathology alone. In contrast, sensitivity of prediction remained unchanged. Conclusions These results show that EEG investigation in patients at risk for psychosis can add to the identification of those patients who will not develop psychosis later on.
