The purpose of this study was to validate the usefulness of the 30-item Geriatric Depression Scale (GDS) in an elder Mexican American population. In this study, community-based Mexican Americans over age 65 were evaluated using a cross-translated version of the GDS as compared to a bilingual psychiatric evaluation. Using a cutpoint of 11 or greater as indicative of depression, the GDS was sensitive (0.80), yet lacked specificity (0.61). Also, the structure yielded distinct differences in the Mexican American elder sample. These results indicate: (1) the GDS may have limited usefulness in screening for depression among Mexican American elders and (2) there may be basic differences in how Mexican American elders present with depression/dysphoria. 相似文献

ObjectivesDepression is under-reported and under-identified by the healthcare professionals. Geriatric depression scale (GDS) is one of the most commonly used instruments for screening the older adults for depression. The current review was done to determine the diagnostic accuracy of various forms of GDS for screening of depression among older adults.MethodsWe conducted systematic search in various databases like Medline, Cochrane library, Sciencedirect and Google Scholar from inception till May 2019. Quality of trials was assessed by Quality Assessment of Diagnostic Accuracy Studies-2 tool. We performed bivariate meta-analysis to obtain the pooled sensitivity, specificity, positive, negative likelihood ratio and diagnostic odds ratio for each of the GDS forms.ResultsTotally 53 studies with 17,018 participants were included in the review. We found the pooled sensitivity and specificity of GDS 30 to be 82 % and 76 % with near higher diagnostic accuracy (AUC = 0.85). GDS 15 had pooled sensitivity and specificity of 86 % and 79 % with higher diagnostic accuracy (AUC = 0.90). GDS 10 had pooled sensitivity and specificity of 87 % and 75 % with AUC = 0.83. Our study found GDS 4 to have sensitivity of 74 % with specificity of 71 %. All the four forms of GDS belonged to right lower quadrant of LR scatter-gram indicating neither confirmation nor exclusion.ConclusionCurrent study found that all the forms of GDS are highly useful for detecting depression among elderly with higher sensitivity and specificity. The diagnostic performance was much better for shorter forms of GDS such as GDS 15 and GDS 10 when compared to GDS 30. 相似文献

OBJECTIVE: To re-examine the test characteristics of the Geriatric Depression Scale (GDS) and the Brief Carroll Depression Rating Scale (BCDRS) in elderly medical inpatients, simulating the procedure followed by clinicians when using screening instruments. DESIGN: Masked comparison of GDS and BCDRS with psychiatric interview. SETTING: Durham VA Medical Center. PARTICIPANTS: 109 consecutively admitted persons aged 70 or over. MEASUREMENTS: Screening by a social worker using GDS and BCDRS on day one, followed the next day by an investigator's structured psychiatric interview to determine the presence of major depressive disorder (MDD). RESULTS: By this method, the sensitivity and specificity of the GDS (cutoff 11) were 82% and 76%, respectively; for the BCDRS (cutoff 6), they were 73% and 79%. Among those with a negative test, the likelihood of MDD dropped from an a priori probability of 10% to an a posteriori probability of 3% with the GDS and 4% with the BCDRS. Among those with a positive test, the likelihood of MDD was 27% for the GDS and 28% for the BCDRS. Excluding patients with cognitive impairment (MMSE < or = 25) only slightly improved test characteristics. CONCLUSION: These estimates are considerably below those reported in earlier studies where concordant screening, two-stage screening, or other methods have been utilized and may impact the decision whether or not to screen for depression using these instruments. 相似文献

This study aimed to validate the TICS and modified TICS (TICSm) in Korean elderly population and to compare MCI and dementia screening ability between TICS and TICSm. TICS and TICSm were administered to 70 cognitively normal (CN), 75 MCI, and 85 dementia subjects, with mini-mental state examination (MMSE) and other cognitive and functional measures. TICS and TICSm scores were highly correlated with other global cognitive and functional scores. The CN vs. dementia discrimination ability of both instruments was as excellent as that of MMSE (sensitivity/specificity at optimal cutoff: 87.1/90.1 for TICS; 88.2/90.0 for TICSm). Although their CN vs. MCI discrimination performances were comparable to that of MMSE, they were far from perfect (sensitivity/specificity: 69.3/68.6 for TICS; 73.3/67.1 for TICSm). There was no significant difference in dementia or MCI screening accuracy between TICS and TICSm. Both of them also showed high test-retest reliability. Our findings indicate that TICS and TICSm are reliable and as valid as MMSE in regard of screening cognitively impaired elderly. In terms of the comparison between TICSm and TICS, however, TICSm has little advantage over TICS for screening dementia and even MCI, in spite of longer administration time and more efforts required. 相似文献

Abstract The validity of an Arabic translation of the Geriatric Depression Scale (GDS) is examined in this preliminary report. The GDS and Mini-Mental Status Exam (MMSE) were administered to 200 elderly Arab-Americans, and the GDS Collateral (GDSCOL) was completed by related informants. The prediction of GDS from GDSCOL scores was significant at the p < .01 level, with addition of the MMSE scores providing a slight increment in prediction. With reported prior diagnosis of depression as a criterion, the specificity of the scales is strong (GDS = .90, GDSCOL = .91), but the sensitivity appeared relatively low. Factors derived from the GDS paralleled those found in prior studies. Additional research is needed to evaluate concordance of the self-report GDS with psychiatrically determined diagnosis of depression. 相似文献

Effect of education on the mini-mental state examination as a screening test for dementia 总被引:4,自引:1,他引:4
We studied whether Mini-Mental State Examination (MMSE) norms for detecting dementia in elderly outpatients vary according to educational attainment. Subjects were 109 elderly outpatients with Alzheimer's dementia and 100 non-demented outpatient controls. Receiver operating characteristics (ROC) of the MMSE were examined among three strata of educational attainment: middle school, high school, and college/graduate school. MMSE ROC curve areas were .95-.96 in the three educational strata. Assuming a dementia prevalence of 10%-30%, the most accurate lower limits of normal for MMSE scores and their attendant sensitivities and specificities were 21 for middle school (.82/.94), 23 for high school (.79/.97), and 24 for college/graduate school (.83/1.00) attainment. These norms accurately classified over 90% of subjects in all three educational strata. We conclude that education-specific norms optimize performance of the MMSE as a screening test for Alzheimer's dementia in elderly outpatients. 相似文献

Self-rated depression scales and screening for major depression in the older hospitalized patient with medical illness 总被引:1,自引:0,他引:1

Until now, no self-rated depression scale had been validated as a screening measure for major depression in the older patient hospitalized with medical illness. The present report establishes the validity of two brief, easily administered depression screening tests, the Geriatric Depression Scale (GDS) and the Brief Carroll Depression Rating Scale (BCDRS), in this population. Structured psychiatric interviews were performed and self-rated depression measures administered to 128 men, aged 70 and over, consecutively admitted to medical and neurological services of a VA hospital. The GDS and BCDRS were both shown to have high sensitivity and specificity for detecting major depression in this setting. Optimal cut-off scores determined by the receiver operating curve characteristics of these tests were 11 for the GDS and 6 for the BCDRS. At a cutoff score of 11, the GDS had a sensitivity of 92%, a specificity of 89%, and a negative predictive value of 99%; lowering the break point to 8 did not increase sensitivity. At a cutoff score of 6, the BCDRS achieved a 100% sensitivity, 93% specificity, and 100% negative predictive value. Whether clinicians decide to implement either of these depression screens in their practice will depend to a large degree on the importance ascribed to the detection of these disorders and on attitudes toward the benefits of treatment. 相似文献

The most visible manifestation of dementia is the progressive inability to activities of daily living (ADL) and to instrumental activities of daily living (IADL). The comprehensive geriatric assessment (CGA) is the validated and recommended instrument to a correct evaluation and decision making in elderly patients. To judge if the decline in cognitive functions is associated with a worsening in functional, emotional and clinical status measured by CGA, we also compared CGA in the same patients stratified for mild, moderate and severe dementia. From September 2004 to November 2005 we studied 47 institutionalized female patients with Alzheimer's disease (AD) and other types of dementia. Mean age was 83.70+/-0.88 years (range 70-101). Their multidimensional evaluation was performed by the CGA. We evaluated geriatric syndromes (AGS, 2004), polypharmacy, frailty, hemoglobin (Hb), serum creatinine (CR) and white blood cells (WBC). We stratified the population in 3 groups for the mini mental state examination (MMSE): severe (MMSE 0-9; 5 patients), moderate (MMSE 10-29; 23 patients) and mild dementia group (MMSE 20-30; 19 patients), and searched for statistical differences in the parameters of CGA. MMSE was significantly related to dependence in ADL (mean=x=1.85), IADL (x=0.57), cumulative illness rating scale-geriatrics (CIRS-G) (x=9.55), geriatric depression scale (GDS) (x=8.71), geriatric syndromes (x=2.49), Hb, CR, WBC and number of drugs (x=6.51, range 2-15) (p=0.001). MMSE low score was also correlated with a worse mini nutritional assessment (MNA) (x=19.5; p=0.003). Frail patients were 61.7%. We found a statistically significant difference in the prevalence of geriatric syndromes between mild vs. moderate dementia group (p=0.02). Mild vs. moderate group, and moderate vs severe group were significantly different concerning Hb levels (p=0.009 and 0.002, respectively). Patients with severe cognitive impairment are more likely to be dependent at ADL and IADL; to present a larger number of comorbidity and geriatric syndromes; to have lower !evels of Hb and higher levels of CR; to be in a worse nutritional status and to take a larger number of drugs. Polypharmacy maybe related to high comorbidity but the risk of irrational drug use should be evaluated. We suggest single testing with CGA as an effective tool providing a comprehensive assessment of elderly, and able to detect unaddressed corrigible problems. 相似文献

OBJECTIVE: To develop and test the effectiveness of a 5-item version of the Geriatric Depression Scale (GDS) in screening for depression in a frail community-dwelling older population. DESIGN: A cross-sectional study. SETTING: A geriatric outpatient clinic at the Sepulveda VA Medical Center, Sepulveda, California. PARTICIPANTS: A total of 74 frail outpatients (98.6% male, mean age 74.6) enrolled in an ongoing trial. MEASUREMENTS: Subjects had a comprehensive geriatric assessment that included a structured clinical evaluation for depression with geropsychiatric consultation. A 5-item version of the GDS was created from the 15-item GDS by selecting the items with the highest Pearson chi2 correlation with clinical diagnosis of depression. Sensitivity, specificity, diagnostic accuracy, and positive and negative predictive values were calculated for the 15-item GDS and the new 5-item scale. RESULTS: Subjects had a mean GDS score of 6.2 (range 0-15). Clinical evaluation found that 46% of subjects were depressed. The depressed and not depressed groups were similar with regard to demographics, mental status, educational level, and number of chronic medical conditions. Using clinical evaluation as the gold standard for depression, the 5-item GDS (compared with the 15-item GDS results shown in parentheses) had a sensitivity of .97 (.94), specificity of .85 (.83), positive predictive value of .85 (.82), negative predictive value of .97 (.94), and accuracy of .90 (.88) for predicting depression. Significant agreement was found between depression diagnosis and the 5-item GDS (kappa = 0.81). Multiple other short forms were tested, and are discussed. The mean administration times for the 5- and 15-item GDS were .9 and 2.7 minutes, respectively. CONCLUSIONS: The 5-item GDS was as effective as the 15-item GDS for depression screening in this population, with a marked reduction in administration time. If validated elsewhere, it may prove to be a preferred screening test for depression. 相似文献

Studies were carried out using the mini mental state examination (MMSE) and the geriatric depression scale (GDS) in 71 elderly patients, in order to establish eventual correlations between cognitive deficit, depression and multiple pathologies. This examination was part of a multidimensional evaluation involving patients over 65 years of age hospitalized in the Department of Clinical Medicine. The patients were divided into 5 grades on the basis of the extent ot functional impairments (from Grade 0 to Grade IV) (British Columbia Classification). Mean MMSE and GDS scores, as well as the mean of the multiple pathologies were calculated in each group. As all the MMSE items could not always be applied, we used a score obtained by dividing the maximum score accomplished by the maximum score applicable. No MMSb impairment was present in 94.11% of the Grade 0 patients, in 57.14% of the Grade I, in 37.5% of the Grade II, and in 40% of the Grade III patients. However, impairment was present in all the Grade IV patients. GDS analysis revealed no depression in 82.35% of Grade 0 patients, in 21.43% Grade I, in 50% Grade II, in 16% Grade III patients. However, some degree of depression was present in all Grade IV patients. The occurrence of patients affected by multiple pathologies was as follows: 1-2 pathologies were recorded in 47.06% of Grade 0 patients, in 57.14% Grade I, in 37.5% Grade II, in 36% Grade III, and in 57.14% of Grade IV patients. 相似文献

Objectives: To assess the prevalence of depressive symptoms in hospitalised and community‐dwelling elderly with and without cognitive impairment and to test the reliability of the four‐ and five‐item geriatric depression scale (GDS) against the 15‐item GDS in screening for depression. Methods: The four‐, five‐ and 15‐item GDS and the abbreviated mental state test were administered to 96 inpatients and 107 community elderly. Results: The prevalence of depressive symptoms was 42.7% in the inpatient group and 53.3% in the community group. The prevalence of cognitive impairment was 39.6% in the inpatients and 37.7% in the community group. The GDS5 had 88.8% sensitivity and 74.3% specificity and the GDS4 had 83.7% sensitivity and 85.7% specificity using the GDS15 as standard. Both were well correlated with the GDS15. Conclusion: The GDS5 and GDS4 are quick, simple and useful initial screening tools for depression. 相似文献

Recent literature on the relationships among dementia, depression, and social support was reviewed, with particular emphasis on the diagnostic differentiation of dementia and depression, and the role of these three entities in elderly individuals with cognitive impairment. Dementia-like symptoms arising in depression and the coexistence of dementia and depression are discussed. Research is necessary to determine more objective criteria for depression and dementia, to provide cognitive and psychiatric testing for elderly individuals, to clarify the diagnostic or prognostic value of the term pseudodementia, and to further elucidate relationships between depression, dementia, and social support. 相似文献

OBJECTIVE: To develop and validate a Spanish version of the Geriatric Depression Scale (GDS) for telephone administration. DESIGN, SETTING, AND PATIENTS: The original version of the GDS was translated into Spanish. A random sample of 282 ambulatory elderly individuals was contacted by phone. Those completing the phone GDS (GDS-T) were asked to schedule an appointment within two weeks in which we collected data on demographics, physical exam, functional and mental status, and a face-to-face version of the GDS (GDS-P). We estimated question-to-question kappa statistics and the Pearson correlation coefficient between the GDS-T and GDS-P scores. We evaluated reliability of the GDS-T and GDS-P using the Cronbach's alpha coefficient. We estimated the sensitivity, specificity, and criterion validity of the GDS using the DSM IV criteria for depression as our gold standard. RESULTS: Thirty patients (11%) refused to participate. Of the remaining 252 patients, 169 (67%) attended the personal interview. The Cronbach's alpha coefficient was 0.85 for GSD-P and 0.88 for GDS-T. Sensitivity and specificity were 88% and 82% for GDS-P and 84% and 79% for GDS-T. The prevalence of depression in the group completing both scales was 12.8% using the GDS-P and 14.9% using the GDS-T (P >.05). Among those who only completed the GDS-T, the prevalence was 22.7% (P <.05) suggesting that depressed patients kept their appointments less frequently. CONCLUSIONS: The telephone GDS had high internal consistency and was highly correlated with the validated personal administration of the scale, suggesting that it could be a valid instrument for screening of depression among elderly ambulatory Spanish-speaking patients. Because the depression rate was significantly higher among those not presenting to the personal evaluation, the adoption of GDS-T may help detect and plan early interventions in patients who otherwise would not be identified. 相似文献

BACKGROUND: An important parallel exists between patients with seasonal affective disorder and institutionalized older adults. Many older patients, as a result of global physical decline and immobility, are confined to their rooms, experiencing little natural sunlight. Thus, institutionalized older adults are at risk for chronic light deprivation. Testing the hypothesis that chronic light deprivation might be responsible, at least in part, for some depression among institutionalized older adults, the aim of this study was to investigate the efficacy of morning bright light treatment on depression among older adults residing in a long-term care facility. METHODS: In a placebo controlled, crossover design, participants (N = 10, six women and four men; M age = 83.8) received each of the following: (i) 1 week (5 days) of 10,000 lux (therapeutic dose); (ii) 1 week (5 days) of 300 lux (placebo); or 1 week of no treatment (control). Each week of light treatment was 5 consecutive days, 30 minutes daily, with a wash-out period consisting of 1 week between conditions. RESULTS: Geriatric Depression Scale (GDS) scores at baseline during all treatment conditions were positively correlated (r = .81, p < .01) with months of institutionalization, where participants with higher GDS scores experienced more time institutionalized. Scores on the GDS remained unchanged during the placebo and control conditions, but depression scores decreased significantly during the 10,000 lux treatment (pretest GDS M = 15 vs posttest GDS M = 11, p < .01). After the 10,000 lux treatment, 50% of the participants no longer scored in the depressed range. Improvement during the 10,000 lux condition was positively correlated (r = .62, p < .05) to baseline GDS scores, where participants with higher GDS scores experienced greater improvement following the 10,000 lux treatment. CONCLUSIONS: The results of the present study suggest that bright light treatment may be effective among institutionalized older adults, providing nonpharmacological intervention in the treatment of depression. Furthermore, the length of institutionalization may play an important role in determining the efficacy of bright light treatment for older adults in the nursing-home setting. 相似文献

OBJECTIVES: To determine the prevalence of depression in a cohort of elderly men as assessed using a 30-item Geriatric Depression Scale (GDS) score and to describe the association between this score and sex steroids, androgen receptor (AR) polymorphism, and general health status. DESIGN: Observational study on the relationship between sex steroid status and health-related parameters. SETTING: Community-based. PARTICIPANTS: Ambulatory men (n=236 in 1997, n=192 in 2000) aged 70 and older at inclusion in 1996, interviewed in 1997 and 2000. MEASUREMENTS: Serum levels of testosterone, estradiol, sex hormone binding globulin (SHBG), dehydroepiandrosterone-sulfate (DHEAS), cortisol, and the AR gene cytosine, adenine, guanine (CAG)-repeat length polymorphism were determined. Free testosterone and free estradiol were calculated. Questionnaires included GDS, 36-item Short Form, and Rapid Disability Rating Scale-2. RESULTS: Median age was 75.3 years (interquartile range=73.5-78.5). A GDS score of 11 or greater was found in 30 (12.7%) men. Age and GDS score were significantly interrelated (P<.01), as were all health-assessment scores. GDS scores were not related to (free) testosterone or AR polymorphism in 1997 or 2000. In 1997 only (n=236), higher GDS scores were related to higher estradiol, free estradiol, and DHEAS levels. CONCLUSION: The data did not support a role for testosterone in depression in elderly community-based men as assessed using the GDS. 相似文献

PURPOSE: There are few longitudinal studies on the subjective quality of life for elderly persons living in their own homes. The purpose of this study was to clarify the validity and reliability of the Japanese version of the Dementia Quality of Life Scale (JDQoL) used in a follow-up survey as part of a longitudinal study in Japan. METHODS: A baseline study was conducted from November 2002 to January 2003, and a year later a follow-up study was conducted from October 2003 to January 2004. The subjects included 72 (19 men and 53 women) elderly persons with dementia living in their own homes. Sixty-six were diagnosed with vascular dementia (VD) and 6 had senile dementia of Alzheimer's type (SDAT). The follow-up study included 60 subjects (VD: 56 and SDAT: 4); _10 of the original subjects were hospitalized, one died, and one was unable to attend daycare because of deterioration. Evaluation was conducted using the JDQoL, MiniMental State Examination (MMSE), and Geriatric Depression Scale (GDS). RESULTS: For the MMSE, the average score of the subjects in the follow-up study was 20.87 (+/- 4.80), which was significantly higher than the score of subjects that were excluded from the follow-up study (17.82 +/- 5.65). At baseline, reliability coefficient was demonstrated by Cronbach's alpha value of 0.744 approximately 0.886. One year later, Cronbach's alpha was 0.723 approximately 0.872. Among the subjects in the follow-up study, MMSE scores decreased significantly compared with the baseline study. In the subscales of the JDQoL, Negative Feelings (reversal item) significantly improved and Feeling of Belonging significantly decreased after one year (p<0.05). Each subscale of the JDQoL had significant correlation with the GDS at baseline and follow-up. Scores on the GDS at baseline had significant correlation with Self Esteem, Positive Feelings, Negative Feelings, and Feeling of Belonging of the JDQoL at follow-up (0.320 to 0.504; p<0.05). CONCLUSION: We demonstrated that the reliability and validity of the JDQoL was comparable to the English version of DQoL. Subjective QOL did not decline for all sub-scales, Negative Feelings in the JDQoL significantly improved compared to baseline. 相似文献

OBJECTIVES: To investigate the reliability and validity of self-reported depression in demented elderly patients. DESIGN: This is the first study to combine the use of multiple depression criteria with dementia and depression control groups. SETTING: Houston Veterans Affairs nursing home and geropsychiatric inpatient unit and outpatient clinic, Baylor College of Medicine's Alzheimer's Disease Research Center. PARTICIPANTS: The total sample included 121 volunteer participants, their informants, and their clinicians, forming four diagnostic groups (27 controls, 37 dementia only, 28 depression only, 29 dementia and depression). MEASUREMENTS: Scales assessing depression, deficit awareness, physical illness, functional disability, caregiver burden, and severity of cognitive impairment were used. RESULTS: Analyses of variance using informant- and clinician-rated depression categories found main effects on patient-reported depression scores for deficit awareness and depression diagnosis but not for dementia diagnosis. Chi-square analyses revealed that demented and depressed patients underreported depression at similarly high rates compared with clinician and informant reports. Regression analyses revealed that deficit awareness accounted for significant variance in self-reported depression accuracy, whereas clinician- or informant-rated depression, severity of cognitive impairment, physical disability, functional status, and caregiver burden were not significant. CONCLUSION: The results of this investigation suggest that the presence of dementia per se does not predict inaccurate depression self-reports. Deficit awareness, which covaries with dementia, appears to account for the majority of the variance in self-report accuracy. These findings were stable across informant- and clinician-rated depression criteria and multiple analyses. 相似文献
