This study’s purpose was to use confirmatory factor analysis to compare published factor-analytic models of the 20-item Purpose in Life test (PIL) to identify the one that provides the best fit to the data. To date many different models have been described, with limited evidence to support whether they are replicable. This study utilized data from undergraduates (N = 620) from a medium-sized university located in the southern United States. Ten different PIL models were tested, with support found for the two-factor model (exciting life, purposeful life) of Morgan and Farsides. Recommendations and implications for research are provided.
