ContextDuring the past 2 decades, a major transition in the clinical characterization of psychotic disorders has occurred. The construct of a clinical high-risk (HR) state for psychosis has evolved to capture the prepsychotic phase, describing people presenting with potentially prodromal symptoms. The importance of this HR state has been increasingly recognized to such an extent that a new syndrome is being considered as a diagnostic category in the DSM-5.ObjectiveTo reframe the HR state in a comprehensive state-of-the-art review on the progress that has been made while also recognizing the challenges that remain.Data SourcesAvailable HR research of the past 20 years from PubMed, books, meetings, abstracts, and international conferences.Study Selection and Data ExtractionCritical review of HR studies addressing historical development, inclusion criteria, epidemiologic research, transition criteria, outcomes, clinical and functional characteristics, neurocognition, neuroimaging, predictors of psychosis development, treatment trials, socioeconomic aspects, nosography, and future challenges in the field.Data SynthesisRelevant articles retrieved in the literature search were discussed by a large group of leading worldwide experts in the field. The core results are presented after consensus and are summarized in illustrative tables and figures.ConclusionsThe relatively new field of HR research in psychosis is exciting. It has the potential to shed light on the development of major psychotic disorders and to alter their course. It also provides a rationale for service provision to those in need of help who could not previously access it and the possibility of changing trajectories for those with vulnerability to psychotic illnesses.

Social functioning as an outcome variable in family interventions with schizophrenic patients has been a relatively neglected area. The requirements of a scale of social functioning to measure the efficacy of family interventions include: the measurement of skill/behaviour relevant to the impairments and the demography of this group; the ability to yield considerable information with an economy of clinical time; and the establishment of ‘comparative’ need through comparison between subscales and with appropriate reference groups. Results from three samples show that the Social Functioning Scale is reliable, valid, sensitive and responsive to change.

Prevention is most important in psychiatry today.^1,2 An indicated approach—targeting intervention—when minimal though detectable signs or symptoms are already present but diagnostic criteria are not met is currently considered the most promising strategy to attenuate, delay, or prevent psychosis.^3,4 The European Prediction of Psychosis Study (EPOS), a unique prospective, multicenter, naturalistic field study, was designed to develop a prediction model of psychosis within a period of 18 months based on a sufficiently large cohort of potentially prodromal subjects.⁵

Summary: Despite the evidence showing that young people aged 12-25 years have the highest incidence and prevalence of mental illness across the lifespan, and bear a disproportionate share of the burden of disease associated with mental disorder, their access to mental health services is the poorest of all age groups. A major factor contributing to this poor access is the current design of our mental healthcare system, which is manifestly inadequate for the unique developmental and cultural needs of our young people, if we are to reduce the impact of mental disorder on this most vulnerable population group, transformational change and service redesign is necessary. Here, we present three recent and rapidly evolving service structures from Australia, Ireland and the UK that have each worked within their respective healthcare contexts to reorient existing services to provide youth-specific, evidence-based mental healthcare that is both accessible and acceptable to young people.

Background. Cognitive therapy for psychotic symptoms often embraces self-evaluative beliefs (e.g. self-worth) but whether and how such beliefs are related to delusions remains uncertain. In previous research we demonstrated that distress arising from voices was linked to beliefs about voices and not voice content alone. In this study we examine whether the relationship with the voice is a paradigm of social relationships in general, using a new framework of social cognition, ‘ranking’ theory.Method. In a sample of 59 voice hearers, measures of power and social rank difference between voice and voice hearer are taken in addition to parallel measures of power and rank in wider social relationships.Results. As predicted, subordination to voices was closely linked to subordination and marginalization in other social relationships. This was not the result of a mood-linked appraisal. Distress arising from voices was linked not to voice characteristics but social and interpersonal cognition.Conclusion. This study suggests that the power imbalance between the individual and his persecutor(s) may have origins in an appraisal by the individual of his social rank and sense of group identification and belonging. The results also raise the possibility that the appraisal of voice frequency and volume are the result of the appraisal of voices' rank and power. Theoretical and novel treatment implications are discussed.
