乳腺癌是全球女性最重要的恶性肿瘤和癌症死亡的主要原因。乳腺癌筛查是降低乳腺癌死亡率的有效途径。本研究旨在为伊朗伊斯法罕市的女性教师提供乳腺癌筛查行为培训。本随机对照实验包括120名教师，随机分为两组（控制组60人，干预组60人）。数据收集工具是基于PEN-3模型的问卷。在干预组进行了四次90分钟的培训课程，以修改其认知和推动因素。在SPSS20和适当的统计测试下，观察了两组在最后一次培训后6个月前后的乳腺自检（BSE）、临床乳房检查（CBE）和乳房X线摄影（MMG）情况。培训后6个月，干预组的BSE（p = 0.02）、CBE（p = 0.04）和MMG（p = 0.01）的频率显著高于对照组。干预组的认知和推动因素的平均分在培训后3个月和6个月时显著高于对照组（p < 0.001）。逻辑回归分析表明，认知因素是教师乳腺癌筛查行为的最强预测因素。本研究结果表明，在教育干预中采用PEN-3模型对改善乳腺癌筛查行为是有效的。版权 2023 Shoushtari-Moghaddam, Shahnazi和Hassanzadeh.

Breast cancer is the most important malignancy and the main cause of cancer deaths among women worldwide. Breast cancer screening is an effective way to reduce breast cancer deaths.The present study aimed to provide breast cancer screening behavior training for female teachers in Isfahan, Iran.This randomized controlled trial included 120 teachers who have randomly divided into two groups (60 in the control group and 60 in the intervention group). The data collection tool was a PEN-3 model-based questionnaire. Four 90 min training sessions were held for the intervention group to modify perception and enablers. Breast self-examination (BSE), Clinical breast exam (CBE), and mammography (MMG) were investigated in both groups before and after 6 months after the last training using SPSS20 and appropriate statistical tests.The frequency of BSE (p = 0.02), CBE (p = 0.04), and MMG (p = 0.01) in the intervention group was significantly higher than in the control group 6 months after training. The mean scores of perception and enablers were significantly higher in the intervention group than in the control group 3 and 6 months after training (p < 0.001). The logistic regression analysis indicated that perception factors were the strongest predictors of breast cancer screening behavior in teachers.Results of the present study indicated that using the PEN-3 model in the educational intervention was effective in improving breast cancer screening behavior.Copyright © 2023 Shoushtari-Moghaddam, Shahnazi and Hassanzadeh.
