Sumario:This study aimed to verify the parameters of the items and persons using the Rasch model for the factors of the Scale of Perceived Social Support (adult version). The sample consisted of 533 students from three Brazilian states, with ages ranging from 18 to 62 years, the majority being female (69%). Participants responded to the Scale of Perceived Social Support (adult version), consisting of 36 items, divided into four elements, namely Affective; Social Interactions; Instrumental; and Coping with Problems. The results indicated the suitability of the elements of the Scale of Perceived Social Support (adult version), based on the Rasch model. All scale items were within the parameters recommended by the model, and the categories of responses proved to be discriminative. The average of the items from the item map was below the average for people, indicating that the items were easily endorsed by the sample.
