ABSTRACT Recently published studies analyzing sensitivity and specificity scores have demonstrated that the brief version of the Patient Health Questionnaire (PHQ [J. Am. Med. Assoc. 282 (1999) 1734]) is a useful tool for the detection of panic disorder and depression.
We aimed to get normative data for the brief PHQ in a representative population-based sample. Sociodemographic data and PHQ data from 2066 subjects were included.
Base rates for PHQ criteria of major depression were 3.8% with the typical 1:2 ratio between males and females (frequency of minor depressive forms: 9.2%). Normative data for the depression total scores were reported. Marital status, education and family income were significantly associated with depression, even after controlling for age and sex. For panic disorder, base rates were 1.8%; age, gender, and marital status were significant predictors. Frequency for panic attacks as a less restrictively defined version were 4.5%.
The normative data provide a framework for the interpretation of depression and panic scores of the PHQ.

    ABSTRACT: Background Living renal donation is of benefit to the allograft recipient. Careful analysis of the donor outcome is necessary with respect to the medical condition, socioeconomic status, and health-related quality of life.Methods All living kidney donors of the Transplant Center at Heidelberg were included. Renal function and co-morbidities were assessed. HRQoL and fatigue symptoms were determined by self-reporting validated test systems [Short Form 36 (SF-36), Multidimensional Fatigue Inventory (MFI-20), Patient Health Questionnaire (PHQ)].ResultsIn total, 430 of 519 living renal donors were eligible to participate: 295 living donors (68.6%) provided informed consent (age at donation 49±11years) with a median time after donation of 77 (24–484) months. Renal function was lower compared with pre-donation (66±15ml/min vs. 88±14ml/min). Blood pressure remained stable (128±14mmHg vs. 129±15 mmHg) with an increase of 56 donors receiving antihypertensive treatment (27.1% vs. 19%). The SF-36 physical component summary score was significantly better for both genders compared with the general population; the SF-36 mental component summary score was lower for female donors, caused by a reduced role functioning. Prevalence of fatigue was increased in female donors between the ages of 40 and 59 years.Conclusions Renal function and blood pressure were as expected from previous studies. Concerning the psychosocial outcome, female donors might be at risk of impairments post donation. Future evaluations will confirm and specify whether these results are necessary.This article is protected by copyright. All rights reserved.

    ABSTRACT: Recently there has been arising interest in automatically recognizing nonverbal behaviors that are linked with psychological conditions. Work in this direction has shown great potential for cases such as depression and post-traumatic stress disorder (PTSD), however most of the times gender differences have not been explored. In this paper, we show that gender plays an important role in the automatic assessment of psychological conditions such as depression and PTSD. We identify a directly interpretable and intuitive set of predictive indicators, selected from three general categories of nonverbal behaviors: affect, expression variability and motor variability. For the analysis, we employ a semi-structured virtual human interview dataset which includes 53 video recorded interactions. Our experiments on automatic classification of psychological conditions show that a gender-dependent approach significantly improves the performance over a gender agnostic one.

    ABSTRACT: For the treatment of obesity, both conservative and surgical procedures are available. Psychological factors are likely to influence the choice of treatment; however, to date, systematic studies that investigate these factors are few in number. The aim of our study was to analyze whether patients who undergo a surgical treatment differ from those who require a conservative treatment in regard to psychological factors, regardless of their somatic conditions. Furthermore, predictors of treatment choice will be examined. A total of 244 patients (189 women), with a mean body mass index of 45.1 kg/m2, underwent a weight reduction treatment, with 126 patients undergoing bariatric surgery and 118 patients participating in a conservative, multimodal outpatient weight reduction program. Differences in the results of the psychological questionnaires between conservatively and surgically treated patients were evaluated through the use of t-tests, χ2-tests and an ANCOVA. For the analysis of the predictors, logistic regression models were calculated. Surgically and conservatively treated obese patients differ in psychological, somatic, and socio-demographic factors. The psychological differences between the groups are independent of obesity-related co-morbidities, such as body mass index (BMI), type 2 diabetes mellitus, hypertension and coronary heart disease. The following psychological and somatic factors equally predict the choice of bariatric surgery: apathy, delegated active coping, a sense of coherence, complaints, type 2 diabetes mellitus, BMI, and age. Longitudinal studies are required to assess the predictive value of the psychological factors in regard to the postsurgical weight course to improve the pre-surgical screening and treatment selection process. The pre-surgical identification of psychological predictors should result in a more personalized medicine course and may ensure long term outcomes.
