Reliability and Validity Testing of the Modified Quality of Interaction Scale.

Background and Purpose: Limited care interaction measurements capture important interaction characteristics that occur during staff-resident care interactions. The purpose of this study was to test the reliability and validity of Modified Quality of Interaction Scale (MQuIS). Methods: Data from an observational study in four assisted living facilities was used. Results: A total of 152 staff-resident care interactions were observed. There was some evidence of reliability based on the Rasch analysis (item reliability of .98). There was some support for validity based on the item fit and hypothesis testing as active resident engagement was significantly associated with positive social and positive care interactions. Conclusions: This study provides some support for the use of the MQuIS to evaluate the quality of care interactions in assisted living settings.
