“…Therefore, the sensitivity and specificity of these screening instruments were not tested. A recent French study showed good screening performances of the fPQ-16 in older help-seeking adolescents (predictive value of 76%) with a cut-off score of 4 positive items (Lejuste et al, 2021)…”

“…Therefore, the sensitivity and specificity of these screening instruments were not tested. A recent French study showed good screening performances of the fPQ‐16 in older help‐seeking adolescents (predictive value of 76%) with a cut‐off score of 4 positive items (Lejuste et al, 2021), whilst the predictive value of the fPCA has not been tested. Future studies should entail both fPQ‐16/ fPCA and diagnosis instruments for CHR‐P that are validated in French in child and adolescent populations to better investigate the internal validity of these screening instruments.…”

“…Amongst screening tools for CHR, the Prodromal Questionnaire (PQ) and the scale of Perceptual and Cognitive Aberrations (PCA) were developed from items existing in the above‐mentioned semi‐structured instruments. In the general help‐seeking population, positively answered items on the PQ and PCA produce correct classification of CAARMS and SPI‐A psychosis risk in around 50% of the cases, distinguishing CAARMS diagnosis from no CAARMS diagnosis with high levels of sensitivity and specificity for predicting CHR‐P status (Ising et al, 2012; Lejuste et al, 2021; McDonald et al, 2019).…”

Aim To validate the French versions of the 16‐items Prodromal Questionnaire (PQ‐16) and the 9‐items scale of Perceptual and Cognitive Aberrations (PCA) to facilitate screening of psychosis risk in native French‐speaking young individuals referred to Child and Adolescent Mental Health Services. Method Participants (N = 87, age range 10—18 years) were diagnosed with a non‐psychotic disorder according to the Diagnostic and Statistical Manual of Mental Disorders. The French versions of the PQ‐16 and PCA were developed using a forward–backward translation procedure. Psychometric properties were tested including (i) internal validity with Pearson correlations and Cronbach's coefficients, and (ii) external validity by correlations with each other's. Results (i) Correlations between fPQ‐16 and fPCA total scores and individual items were mostly >.4. Cronbach's coefficients were .80 for the fPQ‐16 and .61 for the fPCA. (ii) The fPQ‐16 and fPCA total scores were significantly correlated with a large effect size (rs = 0.66). Conclusion The fPQ‐16 and the fPCA are psychometrically acceptable instruments for the screening of potential psychotic symptoms in French‐speaking children and young adolescents under 18 years old referred to Child and Adolescent Mental Health Services.

“…Figure 2 describes the patient referral process between the referrers (usual care settings for adolescents and young adults) and the EIS. As a first step, all potential referrals are screened with a self-rating questionnaire (prodromal questionnaire, short version; PQ-16 [20,21]) by their therapist (referrers). Based on previous studies, a PQ-16 score of 6 has been defined as the cut-off for initiating specialized psychosis risk assessment, using the SIPS or CAARMS interview (depending on the service) [22].…”

Aims: Psychotic disorders are one of the main causes of chronic disability in young people. An at-risk mental state (ARMS) is represented by subclinical symptoms that precede the first episode of psychosis (FEP). The PsyYoung project aims to optimize the detection of an ARMS while reducing unnecessary psychiatric treatments. It investigates the effects of service changes on the referrals and outcomes of young people with ARMS or a FEP. Methods: Six psychiatric outpatient clinics in three cantons (Basel-Stadt, Vaud, and Geneva) participated in the project. They passed through an implementation phase including service changes and the adaptation of a standardized stepped care model for diagnosis and assessment, in addition to measures for increasing the awareness, networking and training of local professionals. Preliminary results: All participating cantons had entered the implementation phase. By March 2023, there were 619 referrals to participating sites. A total of 163 patients (37% FEP and 31% ARMS) and 15 close relatives had participated in individual longitudinal assessments, and 26 patients participated in qualitative interviews. Conclusion: This national collaborative project addresses the issue of early intervention for emerging psychoses, and creates spaces for fruitful reflections and collaboration in Switzerland. The ultimate aim of PsyYoung is to harmonize clinical practices in early intervention of psychosis on a national level.
