A 15-item short form of the psychological and interpersonal relationship scales.
Erectile dysfunction (ED) is a prevalent condition associated with complex psychological and interpersonal issues. The Psychological and Interpersonal Relationship Scales (PAIRS) is a valid and reliable measure of Sexual Self-Confidence, Spontaneity, and Time Concerns associated with ED and its treatment. This paper describes the development and validation of a 15-item, short form of PAIRS (SF-PAIRS). Domain scores and psychometric properties of SF-PAIRS were assessed using data from the validation studies of the full-length (23-item) PAIRS. Items in the two briefer scales (Spontaneity and Time Concerns) were identified using internal consistency analyses and crossvalidated during two multinational clinical trials and a community sample. The scales in SF-PAIRS showed good internal consistency, convergent and discriminant validity, were stable over a 2-week period, and showed sensitivity to treatment. SF-PAIRS is a valid, brief measure of psychological and interpersonal outcomes associated with ED.
