Development and validation of an instrument to detect depression in nursing homes. Nursing homes short depression inventory (NH-SDI).

UNLABELLED: Depression is often overlooked in elderly nursing home residents because symptoms may be masked or dismissed as an inevitable consequence of ageing. Current tools for the detection of depression in institutionalised older people are not always specific. AIMS: To construct and verify an instrument with which to detect depression in elderly nursing home residents (NH-SDI). METHOD: Firstly for the construction, 328 elderly people were selected at random from the residents of 17 nursing homes in France, and examined by a single investigator. The examination included a psychiatric assessment, an evaluation of cognitive function using the MMSE, an evaluation of depressive state using four different instruments (mini-GDS, Goldberg, DMAS, CSDD), and assessment of any changes in behaviour in those suffering from dementia, using the NPI. A second stage was to confirm NH-SDI in 99 institutionalised subjects. RESULTS: Following the selection of items, we created a scale of 16 dichotomous items (NH-SDI). The internal consistency was satisfactory (α Cronbach = 0.85), as was its reliability with a sensitivity of 85.1% and a specificity of 86.5% for a cut-off score above 5. CONCLUSIONS: The NH-SDI appears to be a useful instrument for the detection of depression in nursing homes and can easily be applied by healthcare staff as part of routine procedures.

Specific psychological and behavioral symptoms of depression in patients with dementia.

UNLABELLED: Behavioral and psychological symptoms in dementia (BPSD) are very common, with 90% of patients experiencing at least one during the course of the disease. One-third of persons with dementia have depressive symptoms, and concomitant BPSD are very likely. OBJECTIVE: This study aimed to characterize the psychological and behavioral manifestations of depression in patients with dementia. METHODS: We recruited patients with dementia from several nursing homes in the Limousin region of France. Depression was as diagnosed by the Cornell Scale for Depression in Dementia (CSDD) with a cut-off of 7, and BPSD were assessed using the Neuropsychiatric Inventory (NPI). RESULTS: Of 319 patients with dementia, 42.9% (n =137) were depressed and 75.9% (n = 242) had BPSD. All BPSD were significantly (p < 0.0001) more prevalent among depressed patients, but no significant differences were observed according to sex and age. The NPI showed that the most common additional symptoms in depressed patients were agitation (43.2%), anxiety (42.3%) and irritability (40.1%). Four NPI-based factors were indentified (63.9% of the common variance): factor 1 (disinhibition, irritability, agitation, anxiety), factor 2 (sleep disturbance, aberrant motor behavior, apathy), factor 3 (elation, hallucination, delirium) and the last with eating disorders. Depression in dementia patients was significantly associated with disinhibition, irritability, agitation, and anxiety. CONCLUSION: BPSD are common and a major problem. Before addressing them as isolated symptoms, it is important to consider comorbidity with depression in order to optimize the therapeutic approach.

Use of the Visual Object and Space Perception (VOSP) test battery in two cases of posterior cortical atrophy.

Two patients presenting with predominantly dorsal posterior cortical atrophy were evaluated using the Visual Object and Space Perception (VOSP) test. The objective was to determine whether the VOSP was useful to discriminate damage to the ventral and the dorsal visual pathways. Both patients failed almost all the VOSP subtests, and the battery did not permit confirmation of the integrity of the ventral pathway. In addition, certain subtests evaluating dorsal function were nearly completed, probably due to a compensation strategy. Thus, evaluation using VOSP does not discriminate between predominantly ventral and predominantly dorsal clinical forms of posterior cortical atrophy.

French version of the Rating Scale for aggressive behaviour in the Elderly (F-RAGE): psychometric properties and diagnostic accuracy.

Aggressive behaviour is the most disturbing and distressing behaviour displayed by elderly people. The prevalence of aggressive behaviour is around 50% among psychogeriatric patients. OBJECTIVE: This study sought to analyze the psychometric properties and diagnostic accuracy of the French version of the Rating Scale for Aggressive Behaviour in the Elderly (F-RAGE). METHODS: The F-RAGE was administered to 79 patients hospitalized in a geriatric psychiatry department. A psychiatrist, who was blind to the subjects' RAGE scores, performed the diagnosis for aggressivity based on global clinical impression. The F-RAGE and MMSE were applied by a trained researcher blind to subjects' clinical diagnoses while the Cohen-Mansfield Agitation Inventory and Neuropsychiatric Inventory were administered by medical and nursing staff. Internal consistency, reliability, cut-off points, sensitivity and specificity for F-RAGE were estimated. RESULTS: F-RAGE showed satisfactory validity and reliability measurements. Regarding reliability, Cronbach's α coefficient was satisfactory with a value of 0.758. For diagnostic accuracy, a cut-off point of 8 points (sensitivity=74.19%; specificity=97.98%) and area under curve of 0.960 were estimated to distinguish between aggressive patients and control subjects. DISCUSSION: F-RAGE showed acceptable psychometric properties, supported by evidence of validity and reliability for its use in the diagnosis of aggressive behaviour in elderly.

O comportamento agressivo é o comportamento mais perturbador e angustiante que possa ser apresentado pelos idosos. A prevalência de comportamento agressivo é cerca de 50% entre os pacientes psicogeriátricos. OBJETIVO: Analisar as propriedades psicométricas e acurácia diagnóstica da versão francesa da Escala de Avaliação do Comportamento Agressivo em Idosos (F-RAGE). MÉTODOS: A F-RAGE foi administrada a 79 pacientes internados no departamento de psiquiatria geriátrica. Um psiquiatra que era cego às pontuações F-RAGE dos sujeitos realizou o diagnóstico de DSM-IV com base na impressão clínica global. O F-RAGE e MMSE foram realizados por um pesquisador treinado cego ao diagnóstico clínico dos sujeitos e o Inventário de agitação de Cohen-Mansfield e o Inventário Neuropsiquiátrico pela equipe médica e de enfermagem. Consistência interna, pontos de corte, sensibilidade e especificidade para F-RAGE foram estimados. RESULTADOS: F-RAGE mostrou validade satisfatória e medidas de confiabilidade. Em relação à confiabilidade, coeficiente α de Cronbach foi satisfatória com um valor de 0,758. Para maior precisão de diagnóstico, um ponto de corte de 8 pontos (sensibilidade=74,2%, especificidade=98,0%) e área sob a curva de 0,960 foram estimados para distinguir entre os pacientes agressivos e controles. DISCUSSÃO: F-RAGE mostrou propriedades psicométricas aceitáveis, apoiados por evidências de validade e confiabilidade para sua utilização no diagnóstico do comportamento agressivo em idosos.
