Development and validation of the outcomes and assessment scale for dementia care

Abstract

Objective: To validate the Outcome and Assessment Scale for Dementia Care (OASDC) by comparison with the Multidimensional Observation Scale for Elderly Subjects (MOSES). Methods: The targets were 126 Japanese nurses, together with 126 of their demented patients. The self-administered questionnaire asked the nurses about the condition of their patients. The questionnaire consisted of 20 OASDC items, including the base attributes of the nurses and their patients, and 40 MOSES items. OASDC was subjected to a factor analysis and the correlations between OASDC and MOSES were explored. Results: The factor analysis revealed that OASDC had 5 factors: Self-care ; Tranquility ; Social role; Behavioral and Psychological Symptoms of Dementia (BPSD),; and Caregiver and the cumulative contribution ratio of all five factors was 63.1%. There was a significant correlation between OASDC and MOSES except for the items of care factors (/. = 0.201 to 0.926, p<0.05). Conclusion: The evaluation almost completely secured the validity of the construct validity and contemporary validity of the OASDC.
