Psychometric Testing of the BRI Unmet Need Instrument: A Comprehensive Measure of Dementia Caregivers' Needs

Compared to non-dementia caregivers, family/friend caregivers of individuals with dementia experience more negative caregiving consequences. One reason is the myriad of negatively impacted life domains including: managing symptoms; family communication; financial and legal matters; and finding and coordinating services. Few psychometrically tested measures exist for assessing the range of potential unmet needs of dementia caregivers. Such a measure would describe the frequency and correlates of unmet needs and provide a key outcome for intervention research. This study tested the psychometric properties of a comprehensive measure of unmet needs, the BRI Unmet Need Instrument. Data from 192 family/friend dementia caregivers was used to test reliability and four validity types. Results showed total unmet needs, as well as its nine subscales, had good reliability (Cronbach’s alpha .70 - .95). Discriminant validity was confirmed through factor analyses of the 45 unmet needs and items in measures of depression and care-related strain. Unmet need items loaded on separate factors that were deemed acceptable (.72-.38). Predictive validity was assessed by the association with depression, which was significant and an acceptable range (r = .22, p < .01). Convergent validity was confirmed by significant associations with three caregiver strain measures, mastery (r = .40, p
