Abstract
We developed and evaluated the psychometric properties of the Columbia Behavior Scale for Dementia (CBS-8), a rapid instrument that assesses positive symptoms, to enhance behavioral and psychological symptoms of dementia (BPSD) assessment and treatment in long-term care. Psychometric analyses were performed on CBS-8 data from residents (N = 350, age ≥50 years) in 47 Maryland long-term care facilities referred for neurocognitive and mood evaluation. The CBS-8 demonstrated acceptable internal consistency (α = 0.78) and strong interrater reliability (intraclass correlation coefficient = 1.00). CBS-8 scores were correlated with greater cognitive impairment severity (r = -0.34). The diagnosis of dementia with behavioral disturbance had higher CBS-8 scores than other dementia types (e.g., vascular, unspecified) (p < 0.001, η2 = 0.40). Three CBS-8 factors-motor disinhibition, aggression, and psychosis-explained 65% of the variance in overall BPSD. The CBS-8 could enhance BPSD tracking and treatment, strengthen interdisciplinary collaboration, and aid nursing homes in meeting regulations on unnecessary medication use.
