Introduction: Life satisfaction defines the liking or disliking that people experience about their life processes. It is based on psychological and subjective well-being approaches from positive psychology in the fields of mental health, well-being and quality of life. The life satisfaction scale is an instrument widely used for its measurement, but scarcely validated in university students in the United States Arequipa, Perú. Objective: To analyze the psychometric properties of the life satisfaction scale in university students in Arequipa-Peru. Method: A total of 1,211 people between 17 and 60 years of age participated, it was decided to remove those older than 28 years of age because they had small frequencies (< 20), resulting in a sample of 970 students. Results: The evaluation was made through the CFA, showing that the structure is unidimensional and the fit indices obtained indicate a good fit (χ2(4) = 16.60, p < .05; CFI = .999; TLI = .997; RMSEA = .057; SRMR = .011). The internal consistency showed values higher than .87. Finally, when evaluating the equivalence of the measurement according to sex, the instrument showed measurement invariance. Conclusion: The instrument is valid and reliable for use in measuring life satisfaction.
