Dimensions of the contraceptive attributes questionnaire

This article describes the development and evaluation of the Contraceptive Attributes Questionnaire (CAQ), a research instrument designed to assess the subjective importance of specific contraceptive attributes (Importance) and the perceived characteristics of specific contraceptives (Agreement). Three birth control methods are examined–the sponge, pill, and diaphragm. Factor analyses indicate that the four scales are multidimensional, and as subscales the factors have reasonable internal consistency reliability. The validity of the CAQ was established through comparisons of ratings of women who use different contraceptive methods. The women differed by user status on the ratings of the importance factors and on the ratings of the agreement factors for all three methods rated.
