Identifying elderly depression using the Depression Rating Scale as part of comprehensive standardised care assessment in nursing homes

Objectives: This study used data from the SHELTER (Services and Health for Elderly in Long TERm care) project to explore the benefits of using the Depression Rating Scale (DRS) as part of a standardised needs assessment in UK nursing homes, including a statistical method of effectively identifying characteristics linking to residents’ depression.

Method: About 499 residents in nine nursing homes in south-east England were assessed with interRAI Long Term Care Facilities (interRAI LTCF), a standardised assessment tool containing the validated DRS residents who scored 3 or more on the DRS were considered ‘might suffer from depression’. A list of characteristics associated with depression was then examined using bivariate analysis and logistic regression.

Results: Among the 499 residents assessed, 67.5% were not depressed (DRS?p?=?0.019), ‘diagnosis of COPD’ (COPD, chronic obstructive pulmonary disease) (p?=?0.015), ‘feelings of pain’ (p?=?0.015) and ‘trouble sleeping’ (p?

Conclusion: The article argued that DRS has distinctive advantages for using in UK nursing homes where a preponderance of residents is cognitively impaired, the procedure of screening depression is not regulated and resources to treat depression is relatively scarce. This article also demonstrated how using the DRS as part of a comprehensive standardised needs assessment facilitates analysis of characteristics linking to depression, which has significant policy implications in improving care quality and management.

Sensitivity of the six-item Hamilton Depression Rating Scale

We studied the sensitivity in detecting changes of the 6-item version of the original 17-item Hamilton Depression Rating Scale (HAM-D) and compared it with the more widely used versions among 164 depressed outpatients with and without atypical features before and after treatment with fluoxetine. The 6-item HAM-D was shown to be as sensitive as the 17-, 21-and 24-item versions of this scale. In addition, the different versions of the HAM-D were strongly correlated with each other at baseline and at the endpoint. It appears that the 6-item version of the HAM-D allows the assessment of severity of depression with comparable sensitivity to the standard and more elaborate versions of the same scale.     

Performance of the Hamilton Depression Rating Scale in depressed patients in the United Arab Emirates

Cross-cultural variation in the frequencies and modes of expression of depressive symptoms may influence the validity of depression rating scales. The most widely used instrument for this purpose, namely Hamilton's Depression Rating Scale (HDRS), has not been systematically evaluated in Arab countries. This study evaluates the face validity of the HDRS-21 by studying symptom frequencies, factor structure and symptom clusters in 100 UAE depressed patients. Concurrent validity is tested by comparing total HDRS scores with global estimates of severity made by clinicians, admission status, impairment of social and occupational functioning, and the endogenicity score of the Newcastle (NC) Diagnostic Index. Total HDRS scores show highly significant agreement with three independent measures of severity of depression. Rank orders of the most and least frequent symptoms are consistent with studies of similar design. Marked differences lie in more retardation and somatization and fewer cognitive components in the present study. Principal-component analysis confirmed the heterogeneous structure of the scale, separating a group of core depressive symptoms, and endogenous, somatization, anxiety and psychotic symptom components. The internal consistency (reliability) of the whole scale is moderate, and improves in the core symptom factor. The main conclusion is that the HDRS is sensitive to severity of depression in the UAE culture. However, it measures heterogeneous aspects, and its internal consistency suffers as a result. High levels of retardation and somatization contribute significantly to the total score in socially developing communities.     

Screening for anxiety and depression after stroke: Comparison of the Hospital Anxiety and Depression Scale and the Montgomery and Åsberg Depression Rating Scale

Objective

Anxiety and depression after stroke are frequent, but are often overlooked and not assessed. The aims of the study were to (1) assess the prevalence of anxiety and depression and (2) compare the performance of the Hospital Anxiety and Depression Scale (HADS) and Montgomery and Åsberg Depression Rating Scale (MADRS) as screening instruments for anxiety and depression disorders 4 months after stroke.

Methods

Stroke patients, consecutively admitted to a stroke unit, were assessed with HADS and MADRS 4 months after stroke (n=104). Depression and anxiety disorders were diagnosed using the Structured Clinical Interview for DSM-IV (SCID). Measures were compared in terms of correlations, sensitivity, specificity, positive and negative predictive value, overall agreement, kappa, and ROC curves, using DSM-IV diagnoses of “at least one current significant anxiety disorder” (Anxiety) and “any current depression” (Depression), as the clinical criteria.

Results

Anxiety occurred in 23% of patients and Depression in 19% (13% major depression, 3% minor depression, 4% dysthymia). For Anxiety, the optimal screening cut-off was 4 for HADS-A and 6 for HADS-total; for Depression, optimal cut-offs were 4 for HADS-D, 11 for HADS-total, and 8 for MADRS. At cut-offs commonly used in clinical practice for depression screening (HADS-D: 8, MADRS: 12), the MADRS performed marginally better than the HADS.

Conclusion

Anxiety is as prevalent as depression 4 months after stroke. MADRS and HADS-D perform acceptably as screening instruments for depression, and HADS-A for anxiety after stroke. However, lower HADS cut-offs than recommended for the general population should be considered for stroke patients.     

Predictors of antidepressant response to fluvoxamine obtained using the three-factor structures of the Montgomery and Asberg Depression Rating Scale for major depressive disorders in Japanese patients

Aims:  Fluvoxamine, a selective serotonin reuptake inhibitor, is widely used to treat major depression. However, the symptomatological predictors of the response to fluvoxamine have not been studied.
Methods:  This study included 100 Japanese patients who fulfilled the Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV criteria for the diagnosis of major depressive disorders and whose score on the Montgomery and Åsberg Depression Rating Scale (MADRS) was 21 or higher. Eighty-one patients were included. Patients with a pretreatment MADRS score of ≥31 were defined as 'severe' ( n  = 32) and the rest were defined as 'non-severe' ( n  = 49). The three-factor model of MADRS was used for analysis: the first factor was defined by three items, the second factor was defined by four items, and the third factor was defined by three items representing dysphoria, retardation, and vegetative symptoms, respectively. Fluvoxamine (100–200 mg/day) was administered twice daily for 6 weeks.
Results:  In the non-severe patients, the mean factor 3 score of the non-responders at pretreatment was significantly higher than that of the responders. However, a significant difference was observed in the mean factor 3 scores from 1 week onwards between the non-severe responders and non-responders. Furthermore, the fluvoxamine response rate in the severe patients was 75% and higher than that of the non-severe patients (65.3%).
Conclusions:  This study suggested that a low factor 3 score at pretreatment was a good predictor of the response to fluvoxamine in non-severe patients. The marked efficacy of fluvoxamine in the treatment of severe patients was also confirmed.     

Reliability and validity of the Danish version of the Calgary Depression Scale for Schizophrenia

Depressive symptoms within the range of schizophrenic syndromes constitute a major diagnostic and therapeutic problem. Earlier research has indicated that available depression scales are not adequate when examining mood disturbances in patients with schizophrenia. We have made an attempt to estimate the reliability and validity of the Danish version of the Calgary Depression Scale for Schizophrenia. The external validity has been analysed in relation to the Major Depression Inventory (MDI). The internal validity has been analysed by using Loevinger's coefficient of homogeneity as the primary statistic. For the inter-observer reliability the intra-class coefficients have been calculated. It was shown that a subscale of the Calgary scale has sufficient reliability and validity.     

Experience with a Swedish version of the Geriatric Depression Scale in primary care centres

Objective. The purpose of this study was to use a Swedish version of the Geriatric Depression Scale (GDS-20) for diagnosis of depression in the elderly in primary care. Design. Elderly consecutive patients visiting two primary care centres (⩾65 years of age; N = 1189) were rated by educated nurses using the GDS-20. Setting. All elderly patients attending two primary care centres in an urban-based community in the south of Sweden. Patients. Of the 1189 patients interviewed, 1002 were rated using the GDS-20. Measures. The GDS-20, and in 26 patients also the Geriatric Mental State Schedule—Depression Scale (GMSS-DS). Results. Of 1002 rated patients, 93 had scores of 5 or above on the GDS-20. Further analysis showed that 158 (13.3%) suffered from affective disorders. Conclusion. Depression in the elderly is underdiagnosed in primary care centres. A screening instrument such as the GDS-20 is of value in identifying the patients. © 1997 John Wiley & Sons, Ltd.     

The Montgomery Asberg Depression Rating Scale in bipolar II and unipolar out-patients: A 405-patient case study

The aim of the present study was to find if the Montgomery Asberg Depression Rating Scale (MADRS) can identify symptom differences between bipolar II and unipolar depression. Four hundred and five consecutive bipolar II and unipolar depressed out-patients were interviewed with the Comprehensive Assessment of Symptoms and History structured interview, following DSM-IV criteria, the MADRS, and the Global Assessment of Functioning Scale. The Montgomery Asberg Depression Rating Scale items were not significantly different between bipolar II and unipolar patients. Comparisons among atypical and non-atypical bipolar II and unipolar patients showed that only MADRS items of 'reduced sleep' and 'reduced appetite' were significantly different between atypical and non-atypical patients.     

Concurrent validation of the 21-item and 6-item Hamilton Depression Rating Scale versus the DSM-IV diagnostic criteria to assess depression in patients with Parkinson's disease: an exploratory analysis

OBJECTIVE: The concurrent validity of this 6-item version of Hamilton Depression Rating Scale (HDRS-6) compared to the original 21-item tool (HDRS-21), using the DSM-IV criteria for major depression as the gold standard in patients with Parkinson's disease. METHODS: In analytical study were analyzed: Cronbach's alpha (alpha C), item-total correlation, the receiver operating characteristic curve (ROC) and their area under the curve (AUC), Finally, used the Fagan nomogram. RESULTS: The 115-patient sample with mean illness duration of 7.15 years. HDRS-21 achieved an alpha C of 0.83, HDRS-6 a value of 0.68. Eleven of the HDRS-21 items failed to reach a minimum value. HDRS-21 obtained its better AUC capacity of 0.94 (cut/score of 18/19); HDRS-6 got an AUC of 0.92 (cut/score of 7/8). The Fagan nomogram was (89-94% and 83-90%, respectively). CONCLUSIONS: Our results suggest that HDRS-6 is sufficient, valid and has a sound psychometric structure for use with Parkinson's disease patients.     

Screening for late life depression: cut-off scores for the Geriatric Depression Scale and the Cornell Scale for Depression in Dementia among Japanese subjects

BACKGROUND: Proper screening of depression among older adults depends on accurate cut-off scores. Recent articles have recommended the Geriatric Depression Scale (GDS) and the Cornell Scale for Depression in Dementia (CSDD) for this screening. However, there has been no investigation of the sensitivity and specificity of either scale using Japanese subjects. The purpose of the present study was to identify appropriate GDS and CSDD cut-offs for Japanese older adults. METHODS: The GDS and the CSDD were interview-administered to nondepressed Japanese older adults (n = 74) and to Japanese older adults with a SCID-IV diagnosis of major or minor depression (n = 37). Depressed subjects were also administered the Hamilton Depression Rating Scale (HDRS). Data were also collected on demographic variables, mental status, health status, and medication use. RESULTS: ROC curve analysis identified a cut-off score of 6 for the GDS which had a sensitivity of 0.973, a specificity of 0.959, a False Positive Rate (FPR) of 0.894, and a False Negative Rate (FNR) of 0. A cutoff score of 5 for the CSDD yielded a sensitivity of 1, a specificity of 0.919, a FPR of 0.942, and a FNR of 0. Comparisons indicate current HDRS cut-offs may overlook subthreshold depression. The GDS cut-off score identified among Japanese subjects was the same as that reported for Western subjects. CONCLUSIONS: Due to the substantial prevalence of psychiatric disorders found in false-negative subjects, the above cut-off scores were chosen to optimize the potential for true positives. These scores are recommended for alerting physicians and other caregivers as to when more intensive depression evaluation is needed.     

Depressive symptoms, chronic medical conditions and functional status: a comparison of urban and rural elders in Taiwan

BACKGROUND AND PURPOSE: The associations of depression, chronic condition and functional disability have not been studied well in Taiwan. The present study hypothesized that strong relations between chronic medical conditions, functional status, and the manifestation of depression would be evident; the interrelationships of the interested measures would differ in urban and rural populations METHODS: The study sample was recruited in a community survey in 2001 that included urban and rural elderly dwelling in southern Taiwan. The Chinese-version Geriatric Depression Scale (GDS) was used for data collection on depressive symptoms. Univariate and multivariate logistic regression analyses were performed to identify the predictors for depressive symptoms in urban and rural samples RESULTS: There were 20.1% of urban elders and 12.8% of rural samples classified with depressive symptoms. While controlling for socio-demographics, the prevalence of chronic disease and ADL summary scores were consistently associated with depressive symptoms for urban and rural samples. Cardiovascular disease and hip fracture were significantly predictive of depression for the urban sample, whereas the influence of stroke history was found to be predictive of depression in the rural sample. By individual PADL/IADL items, toileting problems and shopping difficulties were significant predictors of depression for both elderly samples CONCLUSION: The present findings confirm urban-rural differences in the reporting of associations between depressive symptoms, chronic medical conditions, and functional disability. For developing prevention programs on geriatric depression, it is critical to call more attention to chronic medical conditions, functional status, and social support of urban and rural elderly.     

No predictors of antidepressant patient response to milnacipran were obtained using the three-factor structures of the Montgomery and Asberg Depression Rating Scale in Japanese patients with major depressive disorders

Aims:  Milnacipran, a new specific serotonin and norepinephrine re-uptake inhibitor, is as effective as tricyclic antidepressants. Symptomatological predictors of antidepressant response to milnacipran have not been studied until now.
Methods:  This study included 101 Japanese patients who fulfilled the DSM-IV criteria for the diagnosis of major depressive disorders and whose score on the Montgomery and Åsberg Depression Rating Scale (MADRS) was ≥21. Eighty-three patients were finally included. Patients with a pretreatment MADRS score ≥31 points were defined as severe ( n  = 28), and the rest as non-severe ( n  = 55). The three-factor model of MADRS was used for analysis; the first factor was defined by three items, the second factor was defined by four items and the third factor was defined by three items representing dysphoria, retardation, and vegetative symptoms, respectively. Milnacipran was administered twice daily for 6 weeks. The initial dose was 50 mg/day; after a week it was increased to 100 mg/day.
Results:  No significant difference was observed in the mean score of first factor, second factor and third factor at pretreatment time between responders and non-responders in both severe and non-severe patients.
Conclusions:  No predictor of antidepressant response to milnacipran was obtained using the three-factor structures of the MADRS in Japanese patients with major depressive disorders.     

ADHD Rating Scale IV: psychometric properties from a multinational study as a clinician-administered instrument

The development of rating scales for attention-deficit/hyperactivity disorder (ADHD) has traditionally focused on parent-or teacher-rated scales. However, clinician-based instruments are valuable tools for assessing ADHD symptom severity. The ADHD Rating Scale IV (ADHD RS), clinician administered and scored, has been validated as a useful instrument to assess ADHD symptoms among American children and adolescents. In this study, we assessed the psychometric properties of the scale in a recent clinical trial conducted mainly in Europe with over 600 children and adolescents diagnosed with ADHD. The trial was conducted in 11 European countries plus Australia, Israel, and South Africa. Results based on data in the study indicate that this version of the scale has acceptable psychometric properties including inter-rater reliability, test-retest reliability, internal consistency, factor structure, convergent and divergent validity, discriminant validity, and responsiveness. There were low-to-moderate ceiling and floor effects. The psychometric properties were comparable with other validated scales for assessing ADHD symptom severity. These results were consistent across the 14 countries participating in this trial. Overall, the data from this study support the use of the ADHD RS as a clinician-rated instrument for assessing the severity of ADHD symptoms in children and adolescents in Europe.     

Hamilton Depression Scale in dementia

INTRODUCTION : Wide variations in frequency of depression in primary degenerative dementia (PDD) and in vascular dementia (VD) have been reported. This may perhaps be due to inadequacy of common diagnostic tools in detecting depression in the face of cognitive decline. We evaluated here the Hamilton Depression Rating Scale (HDRS) in demented patients with PDD and VD. METHODS : We examined 50 consecutive patients with PDD and 50 consecutive patients with VD. All patients underwent neurological examination and their depression was evaluated using DSM-III-R criteria and the HDRS. The data obtained were analysed for distribution of depression and pattern of responses obtained in the HDRS. Sensitivity, specificity and Youden's J-indices for different cut-off scores of the HDRS in its ability to detect depression in this population were calculated. RESULTS : Dementia was associated with depression in 38% of the patients (DSM-III-R criteria). HDRS scores were higher in depressed patients (z= -5.7, P < 0.0001) with an HDRS cut-off score of 10 being indicative of depression in demented patients. Symptoms related to 'affective' components of the HDRS (such as depressive mood and anxiety) were strongly associated with the diagnosis of depression (Mann-Whitney tests, P < 0.0001). CONCLUSION : Depression is frequent in demented patients. The HDRS has good criterion validity in the evaluation of depression in demented patients. (Int J Psych Clin Pract 2002; 6: 91-94)     

Validity of Hamilton Depression Inventory in Parkinson's disease.

Studies investigating the assessment of depression in Parkinson's disease (PD) are limited. We examined the concurrent validity and the internal consistency of the Hamilton Depression Inventory (HDI) and compared it to the Hamilton and Geriatric Depression Scales. PD patients (n = 79) were recruited from neurology clinics. Diagnosis of depressive disorder was made according to DSM-IV criteria. Receiver operating characteristic curves were used to calculate sensitivity, specificity, and positive and negative predictive values. The HDI exhibited an optimal cutoff for discriminating between depressed and nondepressed PD patients of 13.5/14.0 and is a valid instrument to use in the setting of PD.     

Standardization of the Korean Version of the Geriatric Depression Scale: Reliability, Validity, and Factor Structure

Objective

We developed a Revised Korean version of the Geriatric Depression Scale (GDS-KR) and examined its reliability, validity, and factor structures. We also estimated its optimal cutoff scores for major depressive disorder (MDD) and minor depressive disorder (MnDD) stratified by age and education.

Methods

The GDS-KR was administered to 888 subjects (61 MDD patients, 45 MnDD patients, and 782 normal elders). Its internal consistency and test-retest reliability were examined. Its concurrent validity was evaluated using Pearson correlation coefficients with the Korean version of the Center for Epidemiologic Studies Depression Scale (CES-D-K) and Hamilton Depression Rating Scale (HAM-D). The mean GDS-KR scores of the MDD patients, MnDD patients and normal elders were compared to evaluate its discriminant validity. To evaluate its construct validity, a principal component analysis with varimax rotation was performed. Receiver operator characteristic (ROC) curve analyses were performed to evaluate its diagnostic ability.

Results

Chronbach''s coefficient alpha for the GDS-KR was 0.90 and the test-retest reliability was 0.91 (p<0.01). The Pearson correlation coefficients of the GDS-KR scores with the CES-D-K and HAM-D scores were 0.63 (p<0.01) and 0.56 (p<0.01), respectively. The GDS-KR consisted of 5 factors. The optimal cut-off scores of the GDS-KR were 16/17 for MDD only and 15/16 for both MDD and MnDD. The optimal cutoff scores of the GDS-KR were higher in the less educated and younger subjects. The diagnostic accuracy for MDD of the GDS-KR was higher than that of the CES-D.

Conclusion

The GDS-KR was found to be a reliable and valid questionnaire for screening MDD and MnDD in late life.     

A validation study of The Geriatric Depression Scale short form

The validity of the Geriatric Depression Scale (GDS) short form was assessed in a geriatric affective disorders outpatient clinic (N = 116). The GDS was highly correlated with the Montgomery Asberg Depression Rating Scale (MADRS), and with optimal cutoff scores of 5/6, demonstrated a sensitivity of 85% and a specificity of 74.0%. The GDS appears to be a useful, valid screening instrument in this population.
