BackgroundDepression and anxiety among general hospital patients are common and under-recognized in China. This study aimed toward developing a short questionnaire for screening depression and anxiety in non-psychiatric clinical settings, and to test its reliability and validity.MethodsThe item pool which included 35 questions about emotional distress was drafted through a comprehensive literature review. An expert panel review and the first clinical test with 288 general hospital patients were conducted for the primary item selection. The second clinical test was performed to select the final item in 637 non-psychiatric patients. The reliability and validity of the final questionnaire were tested in 763 non-psychiatric patients, in which 211 subjects were interviewed by psychiatrists using Mini International Neuropsychiatric Interview (MINI). Multiple data analysis methods including principal components analysis (PCA), item response theory (IRT), and receiver operating characteristic (ROC) curve were used to select items and validate the final questionnaire.ResultsThe series selection of items resulted in a 9-item questionnaire, namely Huaxi Emotional-distress Index (HEI). The Cronbach's α coefficient of HEI was 0.90. The PCA results showed a unidimensional construct. The area under the ROC curve (AUC) was 0.88 when compared with MINI interview. Using the optimal cut-off score of HEI (11/12), the sensitivity and specificity were 0.880 and 0.766, respectively.ConclusionsThe HEI is considered as a reliable and valid instrument for screening depression and anxiety, which may have substantial clinical value to detect patients' emotional disturbances especially in the busy non-psychiatric clinical settings in China. 相似文献

BACKGROUND: Depressive disorders are common, and result in high individual and societal costs. The majority of research assessing depression has occurred in urban areas. There is a paucity of research examining the prevalence of and risk factors for depression in rural general practice. AIM: The aim of this study was to examine the prevalence of and risk factors for depression in a rural area of North Wales in the context of a large multi-centre European study. METHOD: One thousand nine hundred and ninety-nine people randomly selected from a health authority database underwent a two-phase screening method to identify depression. The first phase involved patients completing a self-rating postal questionnaire (the Beck Depression Inventory or BDI). In the second phase, those scoring above cut-off underwent detailed diagnostic interview (Schedules of Clinical Assessment in Neuropsychiatry or SCAN). The SCAN diagnostic interview can generate either DSM-IV or ICD-10 diagnoses; the DSM-IV classification system was used here. RESULTS: One thousand two hundred and thirty-nine (63 %) people responded to the initial screening questionnaire. The prevalence rate for all DSM-IV depressive disorders was calculated to be 6.1 % (95 % CI 4.1, 9.0) whereas the prevalence rate for DSM-IV major depressive disorder was 5.1 % (CI 3.37, 7.66). Multivariate analysis indicated that several variables were related to BDI caseness, including gender, employment status, social support and negative life events. CONCLUSION: Levels of reported depression are relatively low in North Wales compared to those observed in a neighbouring urban area using comparable data collection methods. A number of factors traditionally associated with increased risk from depression were predictive of scoring above cut-off on the BDI in a rural North Wales sample. 相似文献

BACKGROUND: Little is known about the longitudinal course of treatment outcome in patients with trichotillomania. The authors conducted a second follow-up assessment on a cohort of hair pullers previously studied. METHOD: Forty-four subjects completed a hair-pulling questionnaire and paper-and-pencil measures of hair-pulling severity and impact, psychosocial functioning, depression, anxiety, and self-esteem. Mean time elapsed between the first and second follow-up assessment was 2.5 years (index evaluation to first follow-up = 3.5 years). RESULTS: Twenty-seven subjects (61.4%) had active treatment since the first follow-up. No significant changes in hair pulling, depression, anxiety, or psychosocial functioning were reported from first to second follow-up. Self-esteem scores significantly worsened during this period (p = .000). A trend toward worsening also existed for psychosocial impact scores. Comparison of scores at index evaluation with second follow-up still showed significant improvement over time for hair pulling (p = .001) but significant worsening in self-esteem (p = .000). Treatment and responder status were unrelated to clinical functioning, with the exception of depression and psychosocial impact. CONCLUSION: Although hair pullers exhibit initial improvement with treatment, scale scores plateau or worsen by second follow-up. Significant worsening in self-esteem at second follow-up may be related to the absence of further improvements in hair-pulling severity. Future research should focus on the interrelationships among self-esteem, depression, and hair pulling during treatment for this disorder. 相似文献

The purpose of this study was to investigate clinical aspects and quality of life (QOL) as risk factors for depression in patients with epilepsy. One hundred and forty outpatients with a diagnosis of epilepsy who were attending our epilepsy center participated. Patients anonymously filled out a questionnaire with clinical data related to epilepsy. Depression level was evaluated by the Hamilton Depression Rating Scale-17 (HAMD-17), and quality of life was evaluated by the Quality of Life in Epilepsy-31 (QOLIE-31). Thirty-six patients with epilepsy suffered from depression (25.7%). Complex partial seizures (OR=0.112) and number of seizure types (OR=3.773) were found to be clinical risk factors for depression. Low scores for seizure worry (OR=0.947) and social function (OR=0.947) on the QOLIE-31 increased the probability of depression in patients with epilepsy. 相似文献

This study describes the development and initial validation of a questionnaire that is suitable for detecting and measuring postpartum negative thoughts. Semistructured interviews with mothers who had suffered from postnatal depression were conducted to inform the content of the questionnaire. The initial questionnaire, alongside other measures, was then administered to a nonclinical sample of mothers with babies aged 0-7 months. Using principal components analysis, a two-factor structure was obtained for the Postnatal Negative Thoughts Questionnaire (PNTQ). The factors included appraisal of cognition, emotion, and situation (ACES) and baby-related and motherhood negative thoughts (BRM-NT). The psychometric properties demonstrated acceptable validity, satisfactory test-retest reliability, and internal consistency. These findings suggest that the PNTQ is a reliable and valid measure for assessing postpartum negative thoughts. Consistent with previous research, findings also suggest that appraisal of negative thoughts is more strongly related to postpartum depression than to the experience of negative thoughts per se. Clinicians may use the PNTQ to offer new mothers the opportunity to assess whether negative thoughts or metacognitive appraisals are being experienced as problematic. Additionally, a direct focus upon the metacognitive appraisals of postpartum negative thoughts may provide a useful adjunct to traditional cognitive therapy approaches. Recommendations for future research are discussed. 相似文献

Decreased binding of tritiated imipramine to platelets has been considered to be a potential biological marker of depression. However, it has been unclear how binding values alter during treatment and recovery. This study investigated imipramine binding parameters and depressive symptoms in 25 patients suffering from major depression at entry to the study and 1, 3 and 6 months later. Although the initial Bmax values were significantly lower in the depressed patients than in healthy subjects, it was not possible to establish a clear relationship between recovery from depression and Bmax. The power of this study to detect an effect of at least 10% of the variance in Bmax due to factors related to recovery from depression was 0.78. 相似文献

When a pair of stimuli separated by an appropriate interval is given to the right visceropleural connective of Aplysia californica the amplitude of the second EPSP elicited in cell R15 is usually smaller than the amplitude of the first EPSP. In the present paper we show that this phenomenon, synaptic depression, can be analyzed in terms of the material flow model of neurotransmitter economics developed in our preceding publications. We specifically show how changes in the 4 model parameters; A, the available pool of transmitter; F, the fraction of the available pool released by a presynaptic action potential; M, the rate of transmitter mobilization into the available pool; and D, the rate constant of demobilization of transmitter from the available pool, all effect synaptic depression. In addition, we show how transient changes in F and M, that are observed immediately and for seconds after a stimulus, influence the time course of synaptic depression. Using this analysis we then tested our previous inferences about changes in the model parameters produced either by pharmacological manipulations or repetitive stimulation, by comparing the observed effects of these manipulations on synaptic depression with the theoretical predictions. The theoretical and experimental findings agreed, thereby strengthening both our previous conclusions of the mode of action of these manipulations and the model itself. 相似文献

Blepharospasm (BSP) is a focal dystonia that results in hyperactivity of orbicular muscles of eyes. These symptoms often result in decreased quality of life (QoL) and symptoms of depression. Botulinum toxin type A is the current first line therapy. The aim of the present study was to analyze the impact of botulinum toxin treatment on the QoL and depressive symptoms in patients with BSP. The QoL was evaluated by means of the Short Form 36 questionnaire. The degree of the intensity of depression was evaluated by means of the Montgomery-Äsberg Depression Rating Scale. Botulinum toxin treatment significantly improves the QoL and reduces the intensity of depressive symptoms in all our study patients with BSP. 相似文献
