Reliability and validity of the Papadum/Pizza test

By Resnick B, Holmes S, Klinedinst NJ et al.

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.
