Background And Purpose:
The purpose of this study was to test the reliability and validity of the Knowledge of Person-Centered Behavioral Approaches for BPSD based on a Rasch analysis.
Methods:
This study used baseline data from the Implementation of the Evidence Integration Triangle for Behavioral and Psychological Symptoms of Dementia (EIT-4-BPSD) clinical trial.
Results:
A total 1,071 nurses completed the test. There was evidence of reliability (alpha coefficient of .99), construct validity with INFIT and OUTFIT statistics in the .6 to 1.4 range, and hypothesis testing with a significant correlation between the Knowledge of Person-Centered Behavioral Approaches for BPSD and positive care interactions.
Conclusions:
Future use of the measure should include more challenging items to differentiate those very high in knowledge of person-centered behavioral approaches for BPSD.
