Association Between the Duration of Untreated Psychosis and Selective Cognitive Performance in Community-Dwelling Individuals With Chronic Untreated Schizophrenia in Rural China.

Importance: Cognitive deficits constitute core features of schizophrenia, but the trajectories of cognitive difficulties in chronic untreated schizophrenia remain unclear.

Objective: To assess the association of neuropsychological deficits with duration of untreated psychosis in individuals with chronic untreated schizophrenia.

Design, Setting, And Participants: Community-dwelling individuals with chronic untreated schizophrenia (untreated patient group) and individuals without mental illness (control group) were recruited from predominantly rural communities in Ningxia, China between June 20, 2016, and August 6, 2019, and administered the Structured Clinical Interview for DSM-IV, the Mini-Mental State Examination, an 8-test version of the MATRICS Consensus Cognition Battery adapted for use in individuals with low levels of education, and a measure of social cognition.

Modeling intention to participate in face-to-face and online lung cancer support groups.

Background: Lung cancer patients and survivors are significantly less likely to use support groups than those with other cancers. In this study, we evaluated the utility and specificity of the Behavioral Model for Vulnerable Populations for modeling intention to participate in face-to-face (F2F) and online lung cancer support groups.

Methods: Adults diagnosed with lung cancer (n = 230) completed measures assessing predisposing, enabling, and need factors associated with intention to use support services.
