Colorectal cancer ranks second among the most prevalent and deadly cancer types for both sexes. Despite having a high mortality rate, colorectal cancer is simultaneously identifiable and preventable through early diagnosis. This study was intended to assess the validity and reliability of the Turkish version of the Health Belief Model Scale for Colorectal Cancer Screening.
This methodological study evaluated the 45-item five-point Likert-type Health Belief Model Scale for Colorectal Cancer Screening. Data collection forms were administered via convenience sampling to 649 participants selected from individuals seeking health services at primary healthcare institutions. The scale's reliability and validity were evaluated via item analyses, content and construct validities, exploratory and confirmatory factor analyses, Cronbach's alpha, McDonald's omega, the Spearman-Brown formula, and test-retest reliability coefficients. The data set was randomly divided into two subsamples. EFA, reliability analyses (Cronbach's alpha, McDonald's omega, Spearman-Brown Coefficient) and item-total statistics were conducted in sample 1 (n = 324). CFA was conducted in sample 2 (n = 325). Item and scale means and, discriminant validity were calculated and tested using the total sample (N = 649).
According to the resulting four-dimensional structure, the factor loads of the subscale items were 0.48-0.89, and subscales explained 49% of the total variance. The Cronbach's alpha coefficients of the subscales were 0.804-0.923. The confirmatory factor analysis revealed good fit indices (χ/df = 2.05; RMSEA = 0.06; CFI = 0.95; IFI = 0.95; GFI = 0.80; RMR = 0.08; NFI = 0.91). The subscale means ranged from 2.23 ± 0.72 to 3.60 ± 0.70 while the item means ranged from 1.95 ± 0.81 to 3.80 ± 0.91.
The Turkish version of the Health Belief Model Scale for Colorectal Cancer Screening is a valid and reliable measuring tool for Turkish people. Except for barrier scale items, those with low means suggest opportunities for improvement. This scale can be applied in Turkey when measuring individuals' health belief perceptions regarding colorectal cancer screening.
结直肠癌在男女最常见和致命的癌症类型中排名第二。尽管死亡率很高，但结直肠癌可通过早期诊断同时被识别和预防。本研究旨在评估土耳其语版结直肠癌筛查健康信念模型量表的有效性和可靠性。
本方法学研究评估了包含45个条目的五点李克特式结直肠癌筛查健康信念模型量表。数据收集表通过便利抽样的方式发放给从初级医疗机构寻求医疗服务的个体中选取的649名参与者。通过项目分析、内容效度和结构效度、探索性和验证性因素分析、克朗巴哈系数、麦克唐纳欧米伽系数、斯皮尔曼 - 布朗公式以及重测信度系数来评估该量表的信度和效度。数据集被随机分为两个子样本。在样本1（n = 324）中进行探索性因素分析、信度分析（克朗巴哈系数、麦克唐纳欧米伽系数、斯皮尔曼 - 布朗系数）和项目 - 总分统计。在样本2（n = 325）中进行验证性因素分析。使用总样本（N = 649）计算并检验项目和量表均值以及区分效度。
根据得出的四维结构，子量表条目的因子载荷为0.48 - 0.89，子量表解释了总方差的49%。子量表的克朗巴哈系数为0.804 - 0.923。验证性因素分析显示拟合指数良好（χ/df = 2.05；RMSEA = 0.06；CFI = 0.95；IFI = 0.95；GFI = 0.80；RMR = 0.08；NFI = 0.91）。子量表均值范围为2.23 ± 0.72至3.60 ± 0.70，而项目均值范围为1.95 ± 0.81至3.80 ± 0.91。
土耳其语版结直肠癌筛查健康信念模型量表是一种针对土耳其人群的有效且可靠的测量工具。除了障碍量表项目外，均值较低的项目表明有改进的机会。该量表可在土耳其用于测量个体对结直肠癌筛查的健康信念认知。
