Abstract

Background and purpose: The purpose of this study was to test the reliability and validity of the Quality of Interactions Schedule (QuIS) using a quantification scoring approach.

Methods: Baseline data from the Evidence Integration Triangle for Behavioral and Psychological Symptoms of Dementia (EIT-4-BPSD) study was used.

Results: A total of 553 residents participated. There was evidence of inter-rater reliability with Kappa scores of .86 to 1.00 and internal consistency based on the Rasch analysis (item reliability of .98). There was some support for validity based on item fit and hypothesis testing as resistiveness to care was significantly associated with total QuIS scores.

Conclusion: This study supports the use of the quantified QuIS to evaluate the quality of interactions over time and to test interventions to improve interactions.

Keywords: Rasch analysis; dementia; geriatrics; interactions.
