Background: Persons with Alzheimer's disease (PWAD) are unable to learn new self memories which are needed to ôupdateö their self identity. PWAD often maintain old self identities such as ôsoldierö or ôyoung motherö that are no longer accurate yet influence their behavior (Harrison, Therrien, Giordani, 2005). Conceptualizing behaviors from past self identities (BPSI) within the Need driven, Dementia compromised Behavior (NDB) framework, self identity is a background factor influencing dementia behavior. However measurement of self identity has been challenging due to it's abstract features. Methods: A self identity questionnaire developed for dementia subjects and family caregivers (Cohen-Mansfield et.al.2000) was tested with 43 mild to moderate stage PWAD and their family caregivers enrolled with the Michigan Alzheimer's Disease Research Center in 2002. IRB approval was obtained, subjects assented, and family caregivers provided consent. In separate interviews, PWAD subjects and their family caregivers were asked to identify social roles, select the three most important, and rate their importance in the past and present on a 5-point scale. All PWAD subjects completed the self-identity task. Two family caregivers did not complete the task and two completed only a portion of the task. Results: Coefficient alpha score for family caregivers and PWAD was .74 and .57 respectively. To measure discriminant validity, correlation of ratings for past and present importance was determined. Among family caregivers, there was no significant correlation between past and present importance of self-identities, confirming that caregivers were ranking AD subjects' self-identity differently between the past and present. However, PWAD subjects had a significant positive correlation (r = .43, p= .009) between past and present importance of the first self-identity. Conclusion: Caregivers clearly distinguished between past and present self identity importance but PWAD subjects did not. These findings have implications for measurement of self identity as a background factor of NDB.
