An analysis of the reliability and validity of the Life-trouble Scale for elderly patients living in geriatric facilities

Abstract

Purpose: The purpose of this study was to develop the Life-trouble Scale for elderly people with dementia to concretely determine their life troubles in geriatric facilities.

Results: The subjects of this study were elderly people living in geriatric health services facilities whose degree of life independence was evaluated as ≥II, who had a diagnosis of dementia, and who agreed to participate in this study.

The study population included 191 subjects (male, n=144, 75.4%; female, n=47, 24.6%). The average age was 85.72 (±6.96) years, the mean degree of need for nursing care was 3.73 (±1.22), and the mean MMSE score was 9.11 (±8.80).

Based on the factor analysis of the Life-trouble Scale, the first factor was named, "Basic Life Behavior and Life Trouble with Communication." The second factor was named, "Life Trouble Associated with Irritation and Confusion". The third factor was named, "Trouble with Human Relations Associated with Feelings and Changes in Consciousness". The fourth factor was named, "Life Trouble Associated with Changes in Consciousness and Repeated Behavior". The Cronbach's α of the 4 factors was 0.884, and the NPI and Crichton rating scales were significantly correlated with the 4 factors.

Conclusion: The results showed that the Life-trouble Scale had reliability and validity, and that it was useful for solving problems in geriatric health services facilities.
