Affinity for political humor: An assessment of internal factor structure, reliability, and validity

Abstract

An 11-item Affinity for Political Humor (AFPH) scale is theorized as a higher-order latent factor with four lower-order latent factors (incongruity, superiority, anxiety reduction, and social connection). The theorized measurement model and several alternative models are tested using confirmatory factor analysis (CFA). In addition, reliability and validity assessments are provided. Analyses are conducted using four data sets collected between December 2009 and March 2011 (total N = 1860). Results reveal the theorized model to fit the data well, but also indicate that an alternative model (four lower-order latent variables only) retains the strongest and most consistent fit across all four data sets. Reliability assessments reveal strong internal consistency for the 11-item AFPH scale, as well as for each of the four sub-dimensions. In addition, correlational analyses reveal the AFPH measures to retain strong validity (i.e., statistically significant and positive correlations with political TV satire consumption).
