Background: People at ultra-high risk (uhr) for developing psychosis are psychopathologically heterogeneous and have a high prevalence of comorbidities. Therefore, identifying such comorbid issues and selecting optimal treatments for individual patients are clinically challenging. This study illustrated UHR individual diversity using the rorschach comprehensive system (rcs) and investigated the usefulness of this system for evaluating comorbid issues and planning optimal interventions. Methods: four adolescents who reported attenuated psychotic symptoms on admission are presented as a case series. In addition to structured interviews for their psychotic symptoms, all participants completed the rcs. Final diagnosis and comorbid issues were determined by combining results from each assessment. Results: all participants met the attenuated positive symptom syndrome based on the structured interview. Two participants had very brief rorschach protocols. Quantitative analysis of rorschach data revealed certain common features: Perceptual-Thinking index (PTI) scores of three, a positive coping deficit index (CDI), and zero of animal movement (fm) responses. The protocols' qualitative thematic analysis provided information about each participant's comorbid issues and concerns. Conclusion: although brief protocols' interpretative validity is limited, the res was a useful means of obtaining insight into mental phenomena and determining uhr individuals' comorbid issues, thereby facilitating the selection of optimal interventions for this heterogeneous population.
