This study aimed to establish evidence regarding the validity (based on the relationship with external variables) of the Scale of Perceived Social Support (Adult Version, EPSUS-A) through a correlation analysis with the Perception Inventory Instruments of Family Support (IPSF) and the Baptista Depression Scale (Adult Version, EBADEP-A). The study sample comprised 102 students aged 18–61 years (M = 26.59, SD = 9.57). The results of the correlation analysis between the instruments show that all the dimensions of the EPSUS-A correlated positively and significantly with that of the IPSF. However, all the factors of the EPSUS correlated negatively and significantly with the EBADEP-A, thus depicting validity in the relationship with the external variables of the EPSUS.
