BACKGROUND Diagnosing depression in chronic pain is challenging due to overlapping somatic symptoms. In questionnaires, such as the Beck Depression Inventory (BDI), responses may be influenced more by pain than by the severity of depression. In addition, previous studies have suggested that symptoms of negative self-image, a key element in depression, are uncommon in chronic pain-related depres...

Abstract Background Experiencing natural disasters is associated with common mental disorders including major depressive disorder (MDD). However, the latent structure of MDD widely debated, and few studies tested factor in Chinese disaster survivors. Therefore, aim current study was to evaluate factorial validity Patient Health Questionnaire-9 (PHQ-9) for DSM-5 (MDD) symptoms earthquake Method ...

OBJECTIVES Neurovegetative and somatic symptoms (such as headaches, heart palpitations and dizziness) have a high prevalence. These symptoms are often indicative for 'masked depression' or 'depression without sadness', especially in older adults. At present, no instrument exists which enables the assessment of these symptoms. This study presents a questionnaire which assesses neurovegetative an...

OBJECTIVE Somatoform disorders (SFD) are defined by symptoms that lack medical explanation. This study examined the type and pattern of patients' causal attributions using a new semistructured interview technique METHODS The Causal Attributions Interview allows to assess and weigh 15 common explanations of physical symptoms. Attributions given by 79 patients with SFD were compared with those ...

The authors examined the sensitivity and specificity of a modified version of the Research Diagnostic Criteria (RDC) for major, minor, and intermittent depressive disorder in 150 elderly male medical inpatients. Four somatic RDC symptoms were replaced with four nonsomatic symptoms. The sensitivity of the modified criteria was 87%, the specificity was 97%, and 96% of patients were correctly clas...

Introduction The term “functional somatic syndrome” refers to several overlapping syndromes that are characterized mostly by symptoms, suffering, and disability and less by disease-specific abnormalities of structure or function. They include, but are not limited to, irritable bowel syndrome (IBS), fibromyalgia (FM), chronic fatigue syndrome (CFS), post-traumatic stress disorder (PTSD), and res...

In chronic smokers, nicotine withdrawal symptoms during tobacco cessation can lead to smoking relapse. rodent models, exposure elicited physical dependence, whereas acute antagonism of nicotinic acetylcholine receptors (nAChRs) immediately precipitated symptoms. Although the central serotonergic system plays an important role in withdrawal, exact raphe nuclei regulating these remain unknown. We...

This study focused on the direct and indirect effect (via sleep duration) of computer use on psychological and somatic symptoms among boys and girls (N = 6112) in 3 different age cohorts (11, 13, and 15-years old) from the 2013/2014 health behaviour in school-aged children (HBSC) study done in Sweden. Structural equation modeling (with SPSS AMOS 22) was used (specifying separate multigroup mode...

OBJECTIVE Functional somatic symptoms, symptoms for which no organic pathologic basis can be found, are more prevalent in girls than in boys, and this difference tends to increase during adolescence. This might be explained, at least in part, by pubertal development. We hypothesized that pubertal maturation predicts the development of most functional somatic symptoms and that this especially is...
