The Wellbeing Index for Persons with Dementia-An Observational Study Based on the Group Observational Measurement of Engagement (GOME).

Abstract

The Group Observational Measurement of Engagement (GOME) was developed to capture the impact of group recreational activities on the engagement and general wellbeing of persons with dementia. The psychometric properties of the GOME were originally described in a study of group activities conducted at one large Canadian geriatric center. Continuing this work in Israel, this article reports on further psychometric properties of the GOME based on observations of 115 persons with dementia from 10 geriatric units, of which four were senior day center units (in three institutions) and six were nursing units (representing five other institutions). Very good inter-rater reliability between research observers was found. Factor analysis suggests that the GOME's four individual-level outcomes can be combined into one indicator, the Wellbeing Index. Validity, examined via agreement between research observers and group activity leaders who were staff members in the facilities where the group activities were conducted, also showed high levels of positive correlations. The GOME provides a practical tool for assessing wellbeing in the context of group activities. It can be useful in clarifying the relative impact of process variables on participants' general wellbeing.
