This study aimed to assess the applicability of the Theory of Planned Behavior (TPB) in predicting intended and self-reported condom use and to examine the effect of previous condom use (PCE) among young adults in rural Ethiopia. A TPB interview was completed by 802 adults (mean age 20.7 years, 74.7% women) and 743 adults (mean age 20.7 years, 76.4% women) reported use of condom at three-months follow-up. The TPB and PCE explained 36% and 2.2% of the variance in intended condom use. Subjective norms discriminated strongly between individuals with and without PCE. The TPB and PCE accounted for 5.3% and 8.5% of the variance in reported condom use. This study concludes that the TPB provided a fairly accurate description of the process underlying intention but was less sufficient to account for self-reported condom use. Ethiopian youth decided on condom use if they anticipated predominantly positive consequences associated with performance and social support, whereas perceived barriers seemed to have less impact. Once they had started to use condoms, they were more likely to continue to do so in the future.
本研究旨在评估计划行为理论（TPB）在预测预期和自我报告的避孕套使用方面的适用性，并考察既往避孕套使用情况（PCE）对埃塞俄比亚农村青年成年人的影响。802名成年人（平均年龄20.7岁，74.7%为女性）完成了TPB访谈，743名成年人（平均年龄20.7岁，76.4%为女性）在三个月随访时报告使用了避孕套。TPB和PCE分别解释了预期避孕套使用差异的36%和2.2%。主观规范在有和没有PCE的个体之间有强烈的区分作用。TPB和PCE分别解释了报告的避孕套使用差异的5.3%和8.5%。本研究得出结论，TPB对意图形成过程提供了相当准确的描述，但在解释自我报告的避孕套使用方面则不够充分。埃塞俄比亚青年如果预期使用避孕套在行为表现和社会支持方面主要会带来积极后果，就会决定使用避孕套，而感知到的障碍似乎影响较小。一旦他们开始使用避孕套，未来继续使用的可能性就更大。
