Reliability and Validity of the Knowledge of Person-Centered Behavioral Approaches for BPSD Test.

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.
