Colorectal cancer is the second most prevalent cause of death from malignancies globally. The present study was conducted targeting the influence of an educational intervention based on the health belief model (HBM) on colorectal cancer screening behaviors in people 50 years old and older.
All 134 samples were included in this quasi-experimental study from Fasa City Health Service Center, equal halves were random into experimental group and control group. The data collection tool was a questionnaire that contained questions on demographic variables, knowledge, and HBM constructs (perceived sensitivity, perceived intensity, perceived benefits, perceived barriers, self-efficacy, and screening behaviors). Both groups answered the questionnaire before and two months following the intervention. There were six 90-minute instruction sessions for the intervention group. SPSS 22 and descriptive and analytical tests (independent t-test, paired t-test, and Chi-square test) were used for data analysis (P < 0.05).
59 women and 75 men took part in this study. A majority of participants were married and had at least high school diploma. The findings indicated that the mean scores for knowledge, each of the HBM's constructs, and cancer screening behaviors did not differ significantly from one another before the intervention between the test group and the control group. However, post the intervention, the intervention group exhibited a significant rise in all mentioned dimensions.
In light of the outcomes, the application of the HBM on colorectal cancer screening behaviors in people 50 years and older was successful. This approach might serve as a helpful foundation for planning, carrying out, and overseeing colorectal cancer screening programs.
结直肠癌是全球第二大常见的恶性肿瘤死亡原因。本研究旨在探讨基于健康信念模型（HBM）的教育干预对 50 岁及以上人群结直肠癌筛查行为的影响。
本准实验研究共纳入法萨市卫生服务中心的 134 例样本，将其随机均分为实验组和对照组。数据收集工具是一份问卷，其中包含人口统计学变量、知识和 HBM 结构（感知敏感性、感知强度、感知益处、感知障碍、自我效能和筛查行为）的问题。两组在干预前和干预后两个月都回答了问卷。干预组进行了六次 90 分钟的指导课程。使用 SPSS 22 以及描述性和分析性测试（独立 t 检验、配对 t 检验和卡方检验）进行数据分析（P<0.05）。
共有 59 名女性和 75 名男性参与了这项研究。大多数参与者已婚，至少拥有高中文凭。研究结果表明，在干预前，实验组和对照组之间的知识、HBM 结构的每个维度以及癌症筛查行为的平均得分没有显著差异。然而，干预后，实验组在所有提到的维度上都显著增加。
鉴于研究结果，HBM 在 50 岁及以上人群中结直肠癌筛查行为中的应用是成功的。这种方法可以为结直肠癌筛查计划的规划、实施和监督提供有益的基础。
