计划行为理论（TPB）、社会认知模型（SCM）和信息-动机-行为技能模型（IMB）在预测避孕套使用方面是有效的。然而，这三种理论模型在预测年轻人使用安全套频率（FCU）方面的充分性尚未得到比较。本横断面研究检验了这三种模型在FCU预测中的适用性和适宜性，并分析了假设构式之间的关系。有过性经验的13-18岁青少年（n = 410）完成了一项评估TPB、SCM和IMB模型构建的调查。参与者是从西班牙北部、南部、东部和东南部随机挑选的18所高中招募的学生。本研究采用结构方程模型（SEM）对TPB、SCM和IBM进行了测试，并利用r构建了模型之间的关系。SEM结果表明，行为技能通过IMB模型假设的动机预测行为，而不是直接通过避孕套使用和性传播感染（STIs）的知识来预测行为。认知因素，如关于避孕套使用和性传播疾病的知识以及避孕套使用自我效能感，在按照SCM建模时直接预测了FCU。结果表明，安全套使用意向是FCU的最佳预测因子，安全套使用意向可通过安全套使用态度和与安全套使用相关的主观规范来预测，而感知控制与FCU无直接或间接关系。基于这些数据，与SCM和IMB模型相比，TPB模型成为预测年轻人FCU的最合适模型。从统计学的角度来看，与其他模型相比，TPB似乎是最适合预测年轻人FCU的模型。总体而言，青少年FCU的主要直接预测因子包括安全套使用意愿、行为技能和认知因素，如性传播感染知识和安全套使用自我效能感。下一步应该是测试包括个人、背景、环境和社会因素在内的综合模型。本文的在线版本（doi:10.1186/s12889-016-2702-0）包含补充材料，授权用户可以使用。
The theory of planned behavior (TPB), socio-cognitive model (SCM), and information-motivation-behavioral skills (IMB) model are effective in predicting condom use. However, the adequacy of these three theoretical models in predicting the frequency of condom use (FCU) among young people has not been compared. This cross-sectional study tested the applicability and suitability of these three models in predicting the FCU, and analyzed the relationships among the postulated constructs. Sexually experienced adolescents (n = 410) aged 13–18 completed a survey assessing the TPB, SCM, and IMB model constructs. Participants were students recruited from 18 high schools, randomly selected from the north, south, east, and southeast of Spain. A structural equation modelling (SEM) analysis was applied to test TPB, SCM and IBM and constructs relationships of each model using R. The results of SEM demonstrated that behavioral skills predict behavior via motivation as hypothesized by the IMB model, but not directly via knowledge about condom use and sexually transmitted infections (STIs). Cognitive factors, such knowledge about condom use and STIs as well as condom use self-efficacy, directly predicted the FCU when modeled as per the SCM. According to the TPB, condom use intention was the best predictor of the FCU, and condom use intention was predicted by attitudes toward condom use and subjective norms related to condom use, but perceived control was not directly or indirectly related to the FCU. Based on the data, the TPB becomes the best-fit model for predicting the FCU among young people compared to the SCM and IMB model. From a statistical perspective, the TPB seems to be the most suitable model for predicting the FCU among young people compared to the other models. Overall, key direct predictors of the FCU in adolescents included condom use intention, behavioral skills and cognitive factors, such as STIs knowledge and condom use self-efficacy. The next step should be to test integrative models that include personal, contextual, environmental, and social factors.
