Introduction: The purpose in life is analyzed within psychological well-being, it deals with the meaning of life thatpeople have, which has implications in areas such as mental health. Currently, precise instrumentation is required for itsassessment of the Ecuadorian population, which at the moment is limited. Objective: To corroborate the unidimensionalstructure of the Purpose in Life Scale-Short version (PIL-SF), the equivalence of measurement according to gender, thereliability and the parameters of discrimination and difficulty in a sample of Ecuadorian adults. Methods: Instrumentalstudy of the PIL-SF under the precepts of Classical Test Theory and Item Response Theory. Participants: 743 Ecuadorianadults (64.2% women and 45.8% men) aged 18 to 73 years (M = 24.7, SD = 7.9). Results: The unifactorial structure ofthe PIL-SF with adequate adjustment was confirmed. In addition, the PIL-SF is invariant at the strong level based ongender and no differences are presented at the level of latent means. The internal consistency reliability is acceptable pergroup and the discrimination and item difficulty parameters are adequate. Conclusion: The PIL-SF is a valid, reliable,and accurate tool to measure the Purpose in Life construct in Ecuadorian adults (18) (PDF) Validation of The Purpose in Life Scale-Short Form in an Ecuadorian sample: factor analysis, reliability and graded response model.
