Application of the 18-Item Dementia Elderly Odayaka Scale in Japan: Evaluation before and after Intervention

Abstract

Introduction: We have developed the Dementia Elderly Odayaka Scale (DEOS) to evaluate psychosocial aspects in older people. The DEOS can be used to assess well-being, such as personhood and social interaction. Objective: The aim of this study was to apply the 18-item DEOS in participants with dementia and to examine the characteristics and usefulness of this scale. Methods: Facility staff provided care for the participants while taking into consideration each participant’s individuality and strong points. The DEOS was applied at the beginning of the interventions and at 1 and 2 months after the start of the interventions. The changes in the participants’ behaviors and their DEOS scores were then evaluated over time. Results: We examined 13 participants (2 men, 11 women) between the ages of 68 and 91 years. In 60% of the participants the DEOS score increased over time. When care interventions were tailored toward communication and leadership for the 2 men, according to each of their individualities, we observed increases in their scores for “social interaction” at 1 and 2 months thereafter. We also observed increases in the scores for “Expression of emotions” category in 2 of the 5 cases who received an aromatherapy massage. Discussion/Conclusion: The changes in the scores over time and the contents of the field notes were consistent with each other, suggesting that the DEOS can be used both to evaluate the effects of interventions and to plan care that takes advantage of each participant’s positive aspects.
