Resumen

This research aims to analyze the validity, reliability and invariance of the AFA-R in university students. A total of 442 university students participated, ranging in age from 18 to 57 years (M = 23,9, SD = 6,29); 280 women (63,3%) y 162 men (36,7%), who responded to the Family and Friends Social Support Scale (AFA-R) and the Multidimensional Scale of Perceived Social Support (MSPSS). A Confirmatory Factor Analysis (CFA), factorial invariance according to the sex and the validity based on the relationship with other variables were conducted, along with a Structural Equation Model (SEM). The results indicated that the original two-factor model of the AFA-R demonstrated adequate fit indices (χ2 = 211.97; gl = 74; CFI =.96; TLI =.95; RMSEA =.074 [IC90% .063-.086]; SRMR =.039). Futhermore, the scale’s dimensions showed adequate reliability indices. Additionally, the factorial structure of the scale provided evidence of strict invariance according to participants’ sex. Similarly, the AFA-R scale demosntrated validity evidence based on its relationship with other constructs through its association with the MSPSS. In conclusion, the findings revealed an adequate internal structure of the AFA-R in the student population, which is invariant when considering two factors, with good internal consistency. Therefore, the AFA-R scale is a promising instrument for measuring family and peer support in the Peruvian context.
