TL;DR: 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.

TL;DR: In this paper, the psychometric properties of the Portuguese version of the Beck Depression Inventory (BDI) were studied on different samples: university students, panic patients and depressed patients.
Abstract: Beck Depression Inventory: Psychometric Properties of the Portuguese Version The psychometric properties of the Portuguese version of the Beck Depression Inventory (BDI) were studied on different samples. The first study investigated the profile obtained with the BDI on a sample of Brazilian university students and compared it with the obtained with versions on different languages and cultures. BDI’s internal consistency was high (0.81) and the overall pattern of results provides evidence to support the construct validity of the Portuguese version. On the second study we have validated the Portuguese version of BDI by obtaining profiles for three samples: university students, panic and depressed patients. On the third study, conducting factorial and discriminant analyses we reported additional psychometric properties as gender differences in depressive symptomatology in a larger nonclinical college sample. We found that women combined affective and self-denigration where as men combined somatic and self-denigration in the same dimension. Discriminant analysis showed that BDI highly discriminates depressive symptomatology in college students and measures specific aspects of depression.

TL;DR: The results indicate that misalignment of circadian and social time may be a risk factor for developing depression, especially in 31- to 40-yr-olds, and these relationships should be further investigated in longitudinal studies to reveal if reduction of social jetlag should be part of prevention strategies.
Abstract: In public health, mood disorders are among the most important mental impairments. Patients with depressive episodes exhibit daily mood variations, abnormal patterns in sleep-wake behavior, and in the daily rhythms of several endocrine-metabolic parameters. Although the relationship between the sleep/circadian processes and mood disorders is poorly understood, clock-related therapies, such as light therapy, sleep deprivation, and rigid sleep schedules, have been shown to be effective treatments. Several studies investigated the relationship between circadian phenotype (chronotype) and depression. These focused mainly on urban populations and assessed diurnal preferences (Morningness-Eveningness score) rather than the actual timing of sleep and activity. Here, we used the Beck Depression Inventory (BDI) in an essentially rural population (N = 4051), and investigated its relation to circadian phenotype (chronotype and social jetlag), assessed with the Munich Chronotype Questionnaire (MCTQ). In our study desi...

TL;DR: The findings support the validity of the Brazilian Portuguese version of the DASS-21 and add to the evidence of the dass-21 quality and ability to assess emotional states separately, eliminating the use of different instruments to assess these states.

TL;DR: Phasic alpha sleep activity was the pattern that correlated better with clinical manifestations of fibromyalgia and exhibited less total sleep time than patients in other subgroups, as well as lower sleep efficiency and less slow wave sleep than patients with a tonic alphaSleep pattern.
Abstract: Objective To characterize the patterns of alpha electroencephalographic sleep and their associations with pain and sleep in patients with fibromyalgia. Methods Pain and sleep symptoms of 40 female patients with fibromyalgia and 43 healthy control subjects were studied before and after overnight polysomnography. Blinded analyses of alpha activity in non–rapid eye movement (non-REM) sleep were performed using time domain, frequency domain, and visual analysis techniques. Results Three distinct patterns of alpha sleep activity were detected in fibromyalgia: phasic alpha (simultaneous with delta activity) in 50% of patients, tonic alpha (continuous throughout non-REM sleep) in 20% of patients, and low alpha activity in the remaining 30% of patients. Low alpha activity was exhibited by 83.7% of control subjects (P < 0.01). All fibromyalgia patients who displayed phasic alpha sleep, activity reported worsening of pain after sleep, compared with 58.3% of patients with low alpha activity (P < 0.01) and 25.0% of patients with tonic alpha activity (P < 0.01). Postsleep increase in the number of tender points occurred in 90.0% of patients with phasic alpha activity, 41.7% of patients with low alpha activity, and 25.0% of patients with tonic alpha activity (P < 0.01). Self ratings of poor sleep were reported by all patients with phasic alpha activity, 58.3% of patients with low alpha activity (P < 0.01), and 12.5% of patients with tonic alpha activity (P < 0.01). Patients with phasic alpha activity reported longer duration of pain than patients in other subgroups (P < 0.01). Additionally, patients with phasic alpha sleep activity exhibited less total sleep time than patients in other subgroups (P < 0.05), as well as lower sleep efficiency (P < 0.05) and less slow wave sleep (P < 0.05) than patients with a tonic alpha sleep pattern. Conclusion Alpha intrusion during sleep can be of different patterns. Phasic alpha sleep activity was the pattern that correlated better with clinical manifestations of fibromyalgia.
