There is increasing interest in promoting person-centered caregiving within gerontology. However, few observational instruments have been developed to measure person-centered caregiving behaviors. In the present study, two innovative coding instruments-the Person-Centered Behavior Inventory (PCBI) and the Global Behavior Scale (GBS)-were used to test the hypothesis that caregivers' person-centeredness would be negatively correlated with residents' resistiveness to care. The study hypothesis was based on the need-driven dementia-compromised theory of behavior. It was expected that person-centered caregiving would better meet residents' needs and be associated with less resistiveness to care. This hypothesis was tested by coding 70 videotaped interactions between 54 caregivers and 20 residents diagnosed with dementia. Resistiveness to care was measured by behaviorally coding residents' resistive behaviors based on the Resistiveness to Care scale. The study hypothesis was supported when the GBS was used to measure person-centeredness, but not when the PCBI was used. The findings provide preliminary support for the predictive and construct validity of the GBS and the PCBI.
