The Cornell-Brown Scale for Quality of Life in Dementia: Spanish Adaptation and Validation

Descrição: The objective of this study was to validate a Spanish version of the Cornell-Brown Scale (CBS) for quality of life (QoL) in dementia. One hundred persons with mild-to-moderate dementia (Diagnostic and Statistical Manual of the American Psychiatric Association, 4th edition) were recruited and interviewed at 5 Spanish centers to obtain sociodemographic information, health perceptions, depressive symptoms (Geriatric Depression Scale 15-item version), functional ability (Barthel Index), dementia severity (Mini-Mental State Examination), specific QoL (CBS), and generic QoL (World Health Organization Quality of Life-BREF version). Analysis was carried out using classical psychometric methods. Internal consistency reliability for the CBS was good (0.87). A priori hypotheses about the relationship between CBS and the World Health Organization Quality of Life-BREF version psychological domain and Geriatric Depression Scale 15-item version were confirmed, indicating good construct validity. Regarding contrasting groups- differences, CBS scores significantly differentiated between healthy and unhealthy and depressed and nondepressed participants but not between those with mild and moderate dementia. The exploratory factor analysis showed a 5-factor solution, which accounted for 63.9% of the total variance of CBS. This study is the first to report the factor structure of the CBS. These results indicate that CBS is a useful tool in assessing persons with dementia. Replication of these results with larger samples is advised. The Spanish version of the CBS is reliable and valid in persons with mild/moderate dementia who are living at home and with a known caregiver.
