El bienestar psicológico es un importante factor protector de la salud mental, particularmente en población vulnerable como los adultos mayores. Por lo tanto, es necesario contar con instrumentos de medición válidos, confiables e invariantes para su adecuado uso, con fines de evaluación e intervención psicológica. Este estudio se propuso analizar las evidencias de validez, confiabilidad e invarianza factorial de la Escala de Bienestar Psicológico (BIEPS-A) en una muestra de adultos mayores peruanos. Participaron 522 adultos mayores, de 60 a 93 años (M = 70.81, DE = 7.62), quienes respondieron la Escala BIEPS-A. Se encontraron adecuados índices de ajuste para un modelo de tres factores correlacionados: x2 /gl = 1.631, CFI = .988, TLI = .984, SRMR = .0470, y RMSEA = .0350. También se halló relación entre las puntuaciones de la BIESP-A y el WHO-5 (r = .504), lo que es evidencia de validez convergente. Así mismo, se halló evidencia de confiabilidad de las puntuaciones con los coeficientes alfa (α) y omega (ω) (> .80). Finalmente, se encontró evidencia parcial de invarianza factorial en función al sexo (∆CFI < .010, ∆RMSEA < .015). Se concluyó que la escala BIEPS-A reúne evidencias de validez, confiabilidad e invarianza parcial respecto al sexo para su correcto uso en adultos mayores peruanos.
Psychological well-being is an important protective factor for mental health, particularly in vulnerable populations such as the elderly. Therefore, it is necessary to have valid, reliable, and invariant measurement instruments for their proper use for psychological assessment and intervention purposes. This study aimed to analyze the evidence of validity, reliability, and factor invariance of the Psychological Well-Being Scale (BIEPS-A) in a sample of older Peruvian adults. Participants were 522 older adults, from 60 to 93 years old (M = 70.81, SD = 7.62), who answered the BIEPS-A Scale. Adequate fit indices were found for a model of three correlated factors: x2/gl = 1.631, CFI = .988, TLI = .984, SRMR = .0470, and RMSEA = .0350. A relationship was also found between the scores of the BIESP-A and the WHO-5 (r = .504, r2 = .254), which is evidence of convergent validity. Likewise, evidence of reliability of the scores with the alpha (α) and omega (ω) coefficients (> .80) was found. Finally, partial evidence of factor invariance based on gender was found (∆CFI < .010, ∆RMSEA < .015). It was concluded that the BIEPS-A scale gathers evidence of validity, reliability and partial invariance with respect to sex for its correct use in older Peruvian adults.
