This study assessed the applicability of the transtheoretical model of behavior change (J.O. Prochaska & C.C. DiClemente, 1983, 1984) to the measurement of contraceptive use among 296 women at high risk for HIV infection and transmission. Structural equation modeling suggested that a measure of general contraceptive use could be used to assess use of oral contraceptives and hormonal implants but that measurement of condom use required separate assessments for main and other partners. Self-efficacy (SE) and decisional balance scales were internally consistent for general contraceptive use, for condom use with main partners, and for condom use with other partners. Consistent with research on other health behaviors, SE scores rose significantly across stages, from precontemplation to maintenance, and a shift in decisional balance was observed for 2 of 3 behaviors. This measurement strategy may enhance the ability to evaluate prevention programs for women at risk.
本研究评估了行为改变的跨理论模型（J.O. 普罗查斯卡和C.C. 迪克莱门特，1983年，1984年）在测量296名艾滋病毒感染和传播高危女性避孕措施使用情况方面的适用性。结构方程模型表明，一项关于总体避孕措施使用情况的测量可用于评估口服避孕药和激素植入物的使用情况，但避孕套使用情况的测量需要对主要伴侣和其他伴侣分别进行评估。自我效能感（SE）和决策平衡量表在总体避孕措施使用情况、与主要伴侣使用避孕套情况以及与其他伴侣使用避孕套情况方面具有内部一致性。与对其他健康行为的研究一致，SE得分从沉思前期到维持期在各个阶段均显著上升，并观察到三种行为中的两种出现了决策平衡的转变。这种测量策略可能会增强评估针对高危女性预防项目的能力。
