The objective of this investigation is to study the involvement of the psychological process in the etiology of perennial allergic rhinitis. Thirty patients with perennial allergic rhinitis, submitted to a Program of Hyposensibilization to Home Dust at the ENT Department, were selected. All patients were studied through psychological interviews and Pfister Colored Pyramid Test. Our results were compared to those obtained by Robert Heiss in his studies of standardization parameters (non rhinitic sample). The study revealed that our patients present intrinsic psychological difficulties characteristic of failures in the affective--emotional development and points out to a neurotic line of personality structuration.
