Aim: The purpose of this study is to develop a theoretical explanation of the prodromal schizophrenia process, or so-called psychosis risk syndrome, by describing patients' own experiences with symptoms, thoughts and feelings.
Methods: A total of 40 interviews were conducted in Taiwan. A Grounded Theory method was selected because of its demonstrated effectiveness in generating theory around dynamic and complex processes on which little is known, all of which is the case with psychosis risk syndrome. Constant comparison analysis, memo writing, member checking, and theoretical sampling were adopted.
Results: A core theoretical framework was developed in which the process of the psychosis risk syndrome is described as proceeding from manageable to uncontrollable. Four stages emerged from the analysis: (1) something is wrong, (2) boiling up, (3) breaking point, and (4) losing control.
Conclusions: The framework resulting from this Grounded Theory research is innovative in presenting patterns and clinical staging that marks the progression from premorbid stage to full-blown psychosis. In addition to specifying the detailed process through in-depth interviews, this research makes two fundamental contributions by: (1) adding evidence to current science and (2) taking patients' experience into consideration to improve the validity of screening tools and design appropriate intervention programs for people with early warning signs of developing schizophrenia.

Understanding psychotic-like experiences in children in the context of dimensions of psychological problems.

Introduction: Although psychotic behaviors can be difficult to assess in children, early identification of children at high risk for the emergence of psychotic symptoms may facilitate the prevention of related disorders. Psychotic-like experiences (PLEs), or subthreshold thought and perceptual disturbances, could be early manifestations of psychosis that may predict a future diagnosis of a psychosis-related disorder or nonspecific correlates of a wide range of psychological problems. Additional research is needed regarding how PLEs map onto dimensions of psychopathology in children.

Reimagining psychosis prevention: responding to the accessibility issues of At-Risk Mental State (ARMS) services through a selective public health approach.

At-Risk Mental State (ARMS) services aim to prevent the onset of first-episode psychosis (FEP) in those with specific clinical or genetic risk markers. In England, ARMS services are currently expanding, but the accessibility of this preventative approach remains questionable, especially for a subgroup of FEP patients and those from specific ethnic minority communities. This commentary outlines the key debates about why a complimentary approach to psychosis prevention is necessary, and gives details for an innovative public health strategy, drawing on existing research and health prevention theory.

Objectives: To establish whether the risk of psychotic disorders in cannabis users changes with time following cannabis cessation using data from the European Network of National Networks studying Gene-Environment Interactions in Schizophrenia (EU-GEI) case-control study.
Methods: The EU-GEI case-control study collected data from first episode psychosis patients and population controls across sites in Europe and Brazil between May 2010 and April 2015. Adjusted logistic regressions were applied to examine whether the odd of psychosis case status changed: (1) with time following cannabis cessation and (2) across different cannabis use groups.
