Abstract
The Oral-Genital Sex Attitude and Behavior (OSAB) questionnaire was developed as an assessment instrument for the investigation of oral-genital sex attitudes and behaviors. The OSAB questionnaire consists of 52 positively and negatively worded statements, presented in a Likert-type format. Statements pertained to receiving and performing oral-genital sex. Data were collected from 274 male and female undergraduate introductory psychology students who participated for partial fulfillment of course credit. Analysis of the OSAB revealed a test-retest reliability of r = .81, p < .001 with an average interitem correlation of .04. It contains seven major factors, accounting for 50.9% of the variance. The OSAB has been determined to possess high face validity.
