An evaluation of the predictive validity and reliability of two measures of person-centered caregiving with nursing home residents with dementia
Abstract
The goal of this dissertation was to test the predictive validity of two measurements of
person-centered care (PCC), the Person-Centered Behavioral Inventory (PCBI), and the Global
behavior scale (GBS). These measures were developed as part of a previous study to assess
certified nurse aide students’ person-centered skills following an educational training program to
increase person-centered behaviors (Grosch, Medvene, & Wolcott, 2008). This study tested
whether the person-centered behavioral inventory and the global behavior scale could
significantly predict scores found using the Resistiveness to Care (RTC) scale. A negative linear
relationship was expected based on the theory of Need-Driven Dementia-Compromised Behavior
(NDB) that specified that resident’s resistiveness to care was a response to needs of theirs that
had not been met. The person-centered behavioral inventory and global behavior scale measured
the caregiver’s person-centered skills. Based on the need-driven dementia-compromised theory
of behavior, it was expected that caregivers who engaged in person-centered behaviors would be
more likely to meet residents’ needs and thus reduce their resistiveness to care. Therefore,
person-centered caregiving, as measured by the person-centered behavioral inventory and the
global behavior scale, were expected to be negatively associated with residents’ resistiveness to
care as measured by the resistiveness to care scale.
This study was conducted in collaboration with Kristine Williams, Ph.D. and the
University of Kansas School of Nursing using an existing data set consisting of 80 caregiving
interactions between nursing staff and residents with dementia. Caregivers’ person-centeredness
was coded using the person-centered behavioral inventory and the global behavior scale.

Residents’ resistiveness to care (e.g. kicking, pulling away, yelling, etc.) during the caregiving
interaction was coded using the Resistiveness to scale.
Results of correlational analyses showed that nursing staffs’ scores on the global behavior
scale marginally predicted residents’ scores for the resistiveness to care scale. The personcentered
behavioral inventory was negatively correlated with the resistiveness to care scale, but
not significantly. An emergent finding was that nursing staff members’ age was the biggest
predictor among variables of residents’ resistive behaviors with age and resistiveness to care
scores significantly negatively correlating. The person-centered behavior measures showed
strong concurrent validity across residents’ varying behaviors and tasks. The measures also
showed good inter-rater agreement and the global behavior scale showed high internal
consistency.
