This paper describes the development and evaluation of the Abortion Attributes Questionnaire (AAQ), an instrument designed to assess the perceived importance of specific characteristics of abortion methods. Women receiving medical abortions (n= 186) and women who chose surgical procedures (n= 118) completed the AAQ. Participants were asked to rate how important each of 21 characteristics would be “when choosing between surgical and medical abortion.” Factor analyses revealed that the AAQ consists of four factors and, as subscales, the factors have good internal reliability. The validity of the AAQ was established through discriminant function analysis and results indicated that three of the four factors predicted choice. Taken together, these findings provide empirical support for the constructs measured by the AAQ.
