“…Participants included adolescents with a schizophrenia spectrum disorder receiving their first treatment of psychosis in one of the seven adolescent psychiatric sites in Switzerland and Germany (VESPA group) (Meng et al, 2009) They were enrolled based on the following inclusion criteria: age of 14 to 18 years, antipsychotic treatment of 4 weeks or less, and living with a parent or guardian for at least 3 months before admission. Forty-two adolescents fulfilled the inclusion criteria.…”

The aim of this study was to assess patterns and correlates of family variables in 31 adolescents treated for their first episode of a schizophrenia spectrum disorder (early-onset schizophrenia [EOS]). Expressed emotion, perceived criticism, and rearing style were assessed. Potential correlates were patient psychopathology, premorbid adjustment, illness duration, quality of life (QoL), sociodemographic variables, patient and caregiver "illness concept," and caregiver personality traits and support. Families were rated as critical more frequently by patients than raters (55% vs. 13%). Perceived criticism was associated with worse QoL in relationship with parents and peers. An adverse rearing style was associated with a negative illness concept in patients, particularly with less trust in their physician. Future research should examine perceived criticism as a predictor of relapse and indicator of adolescents with EOS who need extended support and treatment. Rearing style should be carefully observed because of its link with patients' illness concept and, potentially, to service engagement and medication adherence.Key Words: Family, psychosis, adolescents, expressed emotion, perceived criticism, parental bonding (J Nerv Ment Dis 2014;202: 00-00) E arly-onset schizophrenia spectrum disorders (age of onset < 18 years; henceforth EOS) are associated with many negative outcomes, including worse premorbid functioning, longer duration of untreated psychosis (DUP), a higher number of negative symptoms at initial presentation, and lower response rates to and more side effects with antipsychotic treatment (Meng et al., 2006;Schimmelmann et al., 2007Schimmelmann et al., , 2013a. Furthermore, EOS seems to have distinguishable prodromal features (Fux et al., 2013;Schimmelmann et al., 2011Schimmelmann et al., , 2013b. These findings highlight the importance of identifying malleable prognostic factors in EOS.In adults with schizophrenia, family environment and, to a certain degree, rearing style (i.e., parental bonding; Parker et al., 1988) are important predictors of treatment course. In particular, a link has been established between an adverse family climate (defined as high expressed emotion [HEE] status) and a markedly increased relapse rate and higher risk for a chronic course of illness (Butzlaff and Hooley, 1998;Cechnicki et al., 2013). Although both an EE status and rearing style describe a possibly stressful or supportive environment of patients within their families, both measures seem to be associated only weakly and, therefore, represent separate paradigms of family environment (Parker et al., 1988). Family interventions have proven to effectively decrease the frequency of relapse, hospital admissions, and medication nonadherence as well as to reduce HEE (Pharoah et al., 2010). However, studies looking at firstepisode psychosis have been more ambiguous in their recommendations, and some have questioned the long-term efficacy or even reported potential harmful effects of family interventions with families ...

“…They can lead to delays in the maturation of neuropsychological functions in affected children and adolescents and longterm neuropsychological deficits [1,2] as well as significant impairments in psychosocial functioning [3]. This makes schizophrenia one of the six leading causes of years lived with disability [4].…”

“…This question came into focus with several studies in adults and children that report high rates of standardized lay person or self-report assessed psychotic-like experiences in the general population [15]. However, only three studies addressed this question to date in adults [22] and adolescents [3,23] using appropriate clinical assessments of atrisk criteria. All the three studies found rather low rates of APS or BLIPS in children (age 11-13; 0.9-8.1 % depending on UHR definition [23]) or adults (age 16-40; 0-2 % [22]) as well as COPER (\3 %) and COGDIS (\8.0 %) in adolescents [13].…”

“…Además, son escasas las investigaciones que estudian prevención e intervención de las psicosis de inicio precoz en población infanto-juvenil (<18 años). 26,27 De modo relevante, el German-Austrian-Swiss multicenter study (VESPA) 28 encontró que la prevalencia de los SB en una muestra de adolescentes de la población general es alta (30.2%), aumentando a 81% en la muestra de adolescentes con trastornos psiquiátricos no psicóticos y hasta el 96.5% en los casos con psicosis de inicio precoz. Todo lo anterior, más la ausencia de una herramienta clínica de riesgo de psicosis diseñada para este grupo de edad, puede suponer que se desatiendan importantes aspectos diferenciales de la población infantil y adolescente.…”

IntroductionResearch, diagnosis and treatment of psychotic spectrum disorders have been traditionally dominated by an objectivist approach to their understanding, being primarily focused on positive and negative symptoms. The value of this approach goes without question, but it also involves considerable and widely known limitations. From a complementary perspective, there is a longstanding and promising phenomenological tradition in which the subjective experience of the patient's symptom becomes crucial. The focus on the anomalies of subjective experience, or the Basic Symptom concept specifically, has gained much momentum in the context of early detection of psychosis and schizophrenia.
