Objective: The Premorbid Adjustment Scale (PAS) has gained a reputation as the foremost retrospective assessment tool, although little is known about its reliability and validity. The aim of the study is to examine the psychometric properties of the PAS in a sample of Turkish schizophrenic patients.
Methods: The research was carried out with 80 patients with schizophrenia and 50 healthy people. The sociodemographic form and PAS were applied to both groups. In addition, the Disability Assessment Schedule (DAS)-II and Positive and Negative Syndrome Scale were applied to the patients. In the statistical evaluation, the internal consistency coefficient, explanatory factor analysis, and correlation with other scales were calculated.
Results: The average age of the schizophrenia group was 39.15 ± 12.19 and 45.9 ± 12.18 for control. The average years of education (9.91 ± 3.79 for the schizophrenia group and 11.08 ± 4.73 for control) and gender distribution (55% of the schizophrenia group and 46% of the control group were female) were similar. The internal consistency of the PAS was 0.93, and the subscales were between 0.75 and 0.92. Two-factor solution was observed, explaining 72.97% of the total variance. In regard to convergent validity, the correlation coefficients between the total scores of DAS II and PAS and PAS late and early adolescence and childhood were 0.45, 0.53, 0.48, 0.37, and 0.22, respectively ( < .001). The correlation coefficients between the total score of PAS and the total score of DAS 1, DAS 3, DAS 4, DAS 5, and DAS 6 were calculated as 0.46, 0.43, 0.39, 0.48, and 0.44 ( < .001), respectively. The PAS significantly differentiated the schizophrenia group from the control group.
Conclusion: The PAS is reliable and valid for Turkish.

Adult neurogenesis has most often been studied in the hippocampus and subventricular zone-olfactory bulb, where newborn neurons contribute to a variety of behaviors. A handful of studies have also investigated adult neurogenesis in other brain regions, but relatively little is known about the properties of neurons added to non-canonical areas. One such region is the striatum.

Background: Studies of salivary cortisol levels in psychosis have yielded inconsistent findings, which may be attributable to heterogeneity in cortisol measurement, illness stage, and approaches to dealing with sampling factors and potential confounders. To address these issues, we performed an individual participant data (IPD) meta-analysis comparing individuals at different stages of psychosis to controls using five different salivary cortisol measures and explored potential effect modifiers.
Methods: Salivary cortisol data from five London-based cohorts were used to derive the cortisol awakening response, total daytime cortisol output, basal cortisol, and diurnal slope measures (wake-to-evening and peak-to-evening).

Background And Hypothesis: Convergent evidence shows the presence of brain metabolic abnormalities in psychotic disorders. This study examined brain reductive stress and energy metabolism in people with psychotic disorders with impaired or average range cognition. We hypothesized that global cognitive impairment would be associated with greater brain metabolic dysregulation.

Background: Deaths in Australia and other high-income countries increasingly involve multiple conditions. However, key burden of disease measures typically only use the underlying cause of death (UC). We quantified sex and cause-specific years of life lost (YLL) based on UC compared with a method integrating multiple causes of death.

Study Design: With this randomized, participant-blinded, sham-controlled trial, we expanded our previous results. Specifically, we examined neurofeedback effects from the STG, an area associated with auditory hallucinations.
