Evidencia psicométrica de la escala de satisfacción con la vida de diener en adultos mayores peruanos

Introduction: In recent years, satisfaction with life has aroused the interest of gerontological research, thus being one of the most used concepts to measure subjective well-being, in addition to being an indicator of successful aging. Materials and methods: The psychometric properties of the Diener’s Satisfaction with Life Scale were assessed in Peruvian elderly individuals. The instrument was applied to 236 elderly from the city of Trujillo (78.4 % female and 21.6 % male), with an average age of 72.8 years old, and their standard deviation = 6.90. In order to obtain convergent and discriminant validity, the tests Single Item of Satisfaction with Life Scale, Brief Resilient Coping Scale and the Geriatric Depression Scale were conducted. Results: Diener’s Satisfaction with Life Scale shows a one-dimensional structure (χ2 = 10.960, df = 5, p = .05, χ2/df = 2.192,GFI = .983,CFI = .994,NFI = .988;RMSEA = .071 [CI 90 % .000, .129]; and SRMR = .013), presenting positive correlations with resilience and negative correlations with depression. Moreover, it presents a high reliability index estimated by the method of internal consistency with the Cronbach’s Alpha Test (α = .93), Omega coefficient (ω = .93; CI 95 %: .92-.95) and GLB = .94. Conclusion: For purposes of research —among other—, we recommend the use of the Diener’s Satisfaction with Life Scale for Peruvian elderly persons.
