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.

Quality Control
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...

Measures of Intelligence
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this;...
