Purchasing nonprescription contraceptives: The underlying structure of a multi-item scale

The authors develop a multi-item scale measuring attitudes associated with purchasing nonprescription contraceptives. Although contraceptives represent a common as well as consequential purchase for many people, published research has not addressed measures of attitudes associated with this purchase decision. A scale development method is presented measuring both male and female consumer attitudes toward purchasing contraceptives. Ultimately, a multi-item scale demonstrating a high degree of invariance across 2 samples (men and women) is developed.
