Reliability and validity of the Papadum/Pizza test.

PURPOSE: The purpose of this study was to test the psychometric properties of the Papadum/Pizza Test.

DESIGN

This was a descriptive study.

SAMPLE: Participants included 80 individuals living in low-income senior housing. The majority were female (70 %) and Black (70 %) older adults.

MEASURES: Demographics, the Patient Health Questionnaire-2, the Papadum/Pizza test, and the Clock test were obtained.

DATA ANALYSIS: Descriptive statistics were done. A Cohen's Kappa was calculated to evaluate inter-rater reliability. Rasch analysis using Winsteps was done to test internal consistency, Differential Item Functioning (DIF), and model testing for construct validity. Hypothesis testing was done using Pearson correlations.

RESULTS

There was a Cohen's kappa of .98, an alpha coefficient of .95, no DIF between groups, and all items fitting the model, and all hypotheses tested were supported.

CONCLUSION

The study provided support for reliability and validity of the Pizza Test when used with older adults in senior housing.
