The meaning of life is the central assumption of Logotherapy and Existential Analysis and the PIL-Test (Purpose in Life Test) has been consolidated as one of the most relevant instruments for its assessment. This study examined the instrument's factorial structure, whose analyses still sustain a controversy on the most reliable fit to explain it. A total of 200 Psychology students participated in the study, with average age of 23.62 years (SD = 7.071). Besides investigating the discriminant power, homogeneity and internal consistency of the instrument's items, an exploratory factorial analysis was conducted based on the polychoric correlation matrix and the DWLS estimation. The study gathered satisfactory psychometric evidence, indicating a one-factor structure for the matrix of the items with acceptable fit indices, as well as corroborating previous suggestions regarding the exclusion of certain items aimed at a smaller and more parsimonious structure.

Keywords : meaning of life; logotherapy; factor analysis.
