Validation of a Portuguese version of the Beck Depression Inventory and the State-Trait Anxiety Inventory in Brazilian subjects.
TLDR
The present data demonstrate that the psychometric properties of the Portuguese versions of the BDI and STAI are comparable to the original English language versions of these questionnaires, thereby indicating their use in clinical situations.Abstract:
We have validated a Portuguese version of the Beck Depression Inventory (BDI) and State-Trait Anxiety Inventory (STAI) tests by obtaining profiles for three Brazilian samples: 270 university students, 117 panic patients and 30 depressed patients. The mean BDI scores were higher for depressed patients (25.2 +/- 12.6), intermediate for anxious patients (15.8 +/- 10.3) and lower for students (8.5 +/- 7.0). Mean STAI scores for anxious (52.8 +/- 11.4) and depressed patients (56.4 +/- 10.5) were higher than for the student sample (40.7 +/- 8.6). BDI and STAI scores were correlated significantly in all samples. The internal consistency of the Portuguese version of BDI is in agreement with the literature (0.81 for students and 0.88 for depressed patients). The present data demonstrate that the psychometric properties of the Portuguese versions of the BDI and STAI are comparable to the original English language versions of these questionnaires, thereby indicating their use in clinical situations.read more

TL;DR: Overnight S 100B variation and morning S100B were associated with PD severity and perceived sleep disruption and Noradrenergic-astrocytic dysfunction is hypothesized as a possible mechanism underlying these findings.

TL;DR: Investigation of the clinical correlates of early treatment discontinuation among obsessive-compulsive disorder patients found psychiatric comorbidities were associated with discontinuation rates of specific treatments and treatment modality scores were significantly associated with the probability of treatment discontinuations.

TL;DR: This study provides the first evidence of an acute anxiolytic effect of ascorbic acid in a small sample with narrow sociodemographic characteristics, composed mainly of healthy young females enrolled in post‑graduation courses without controlling diet, physical activity, and formal psychiatric diagnosis.
