Evidence psychometric initial of the scale of self-efficacy for aging (EAEE) in peruvian elderly [Evidencias psicométricas iniciales de la escala de autoeficacia para envejecer (EAE) en adultos mayores peruanos]

ABSTRACT The study examines the psychometric evidences of the Self-Efficacy Scale for Aging (EAEE) in a sample of 400 older adults (75.2% women and 24.8% men) from the city of Trujillo (Peru) with an average age of 73.37 years (DE = 7.86). The participants completed the EAEE along with measures of life satisfaction and depression. The exploratory factor analysis (AFE) revealed that the EAEE presented a one-dimensional factorial structure. The confirmatory factor analysis (CFA) showed that the one-dimensional model had an acceptable fit (S-Bχ2 = 54.02, df = 345 p = .001; S-Bχ2/df = 1.54; CFI = .97; RMSEA = .052 [IC90% .021, .078]; y SRMR = .049; AIC= 118.96) and an adequate reliability (ω = .88 [IC95% .84 – .91]; α = .88 [IC95%: .84 - .91]). EAEE scores correlated positively with satisfaction with life (r = .56, p< .01 [IC95%: .46, .79]) and negative with depression (r = -.48, p< .01 [IC95%: -.37, -.73]). The results suggest that the EAEE presents evidence of validity based on the internal structure, convergent and discriminant, as well as an adequate reliability

Los participantes completaron la EAEE junto con medidas de satisfacción con la vida y depresión. El análisis factorial exploratorio (AFE), reveló que la EAEE presentaba una estructura factorial unidimensional. El análisis factorial confirmatorio (AFC), mostró que el modelo unidimensional tenía un ajuste aceptable (S-Bχ2 = 54.02, df = 345 p = .001; S-Bχ2/df = 1.54; CFI = .97; RMSEA = .052 [IC90% .021, .078]; y SRMR = .049; AIC= 118.96) y una confiabilidad adecuada (ω = .88 [IC95% .84 – .91]; α = .88 [IC95%: .84 - .91]). Los puntajes de la EAEE se correlacionaron de manera positiva con la satisfacción con la vida (r = .56, p< .01 [IC95%: .46, .79]) y negativa con la depresión (r = -.48, p< .01 [IC95%: -.37, -.73]). Los resultados sugieren que la EAEE presenta evidencias de validez basada en la estructura interna, convergente y discriminante, así como una adecuada confiabilidad
