Low-level temporal coding impairments in psychosis: preliminary findings and recommendations for further studies

The authors investigated whether difficulties with temporal event coding, previously reported in patients with schizophrenia, are already present during first-episode psychosis (FEP). In this experiment, the subjective judgments of the simultaneity of visually presented stimuli were compared between 11 healthy controls, 9 patients with chronic schizophrenia (CSZ), and a sample of 11 FEP patients. Participants were asked to indicate whether 2 vertical bars appeared at the same time or at different times on a computer monitor. CSZ patients' thresholds were elevated, and the FEP sample showed higher thresholds relative to controls. Although preliminary, these findings indicate a generalized disturbance in event-structure coding at early stages of psychosis and question the specificity of its disturbance. Considering the proposed relationship between event-structure coding and the experience of time in general, this study recommends that future studies refocus on psychosis in general, rather than on schizophrenia as a particular case of abnormal temporal processing. In addition, it is suggested that the relevant psychopathology will be best determined by means of a comprehensive analysis of low-level temporal coding performance in different types of psychosis.     

Prediction of Suicide Intent in Aboriginal and Non-Aboriginal Adolescent Inpatients: A Research Note

The relationship among depressive symptoms, anxiety, hopelessness, and suicidal intent was explored in a group of 77 adolescents who had been hospitalized after attempting suicide. Regression analyses indicated that hopelessness was the only significant predictor of suicide intent in Caucasian patients, and depressed mood was the only significant predictor in the Aboriginal group. Clinicians should be aware that measures of hopelessness may be of limited value in assessing suicidal risk in Aboriginal adolescents.     

Family Functioning and Attachment Among Young Adults in Western and Non-Western Societies

Abstract

Family functioning (FF) is associated with patterns of adults’ close relationship attachment, which works differently in western and non-western societies. In this study, the relationship between FF and attachment (A), as well as the difference in relationship between FF and A across western and non-western societies were examined. A total of 600 young adults (294 males, 306 females) were recruited from western and non-western societies through the SurveyCircle and social media and communication applications. The data was analyzed using PLS-SEM and multigroup analysis, and the results showed that in western and non-western societies, family adaptability and cohesion were significantly associated with anxiety, close, and depend attachments. Unexpectedly, higher family adaptability was associated with higher anxiety attachment. The associations among family adaptability and cohesion with anxiety, close, and depend attachments showed that the strengths of the relationships are significantly different in western and non-western societies, except for the association between family cohesion and anxiety. Based on these results, the cultural differences in terms of FF and young adults’ close relationship attachment were presented for future research, family therapy, and the society.
