INTRODUCTION
Colorectal cancer (CRC) is one of the leading cancers in Malaysia where new cases are increasing every year. The aim of this study was to test the reliability and validity of a newly developed questionnaire on knowledge, attitude and dietary practices (KAP) related to CRC for the Malay population.
METHODS
The respondents were conveniently selected among visitors attending an outpatient clinic in a tertiary hospital. We excluded those with any cancers, chronic diseases and those that were illiterate. The exploratory factor and reliability analyses were conducted.
RESULTS
A total of 108 respondents were recruited of which 67.7% were males and the mean age was 54.59 years (standard deviation 8.93). The Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy values for KAP were 0.64, 0.66 and 0.67, respectively ( < 0.001). The 17 items of knowledge formed five domains with loading factors ranging from 0.54-0.89. The six items of attitude formed two domains with loading factors ranging from 0.64-0.80 and the 15 practices had four domains with loading factors ranging from 0.52-0.83. The total variances explained for each KAP were 61.02%, 56.41% and 53.12%, respectively. The internal consistency Cronbach alpha values on KAP were 0.61, 0.60 and 0.70, respectively.
CONCLUSION
The final questionnaire is suitable for measuring KAP related to CRC among the Malay population.
引言
结直肠癌（CRC）是马来西亚主要的癌症之一，每年新发病例都在增加。本研究的目的是测试一种新开发的关于结直肠癌相关知识、态度和饮食习惯（KAP）问卷对马来人群的可靠性和有效性。
方法
在一家三级医院门诊就诊的患者中方便地选取受访者。我们排除了患有任何癌症、慢性病以及文盲患者。进行了探索性因素分析和可靠性分析。
结果
共招募了108名受访者，其中67.7%为男性，平均年龄为54.59岁（标准差8.93）。KAP的Kaiser-Meyer-Olkin（KMO）抽样适当性值分别为0.64、0.66和0.67（<0.001）。17项知识形成了五个领域，载荷因子范围为0.54 - 0.89。6项态度形成了两个领域，载荷因子范围为0.64 - 0.80，15项饮食习惯形成了四个领域，载荷因子范围为0.52 - 0.83。每个KAP解释的总方差分别为61.02%、56.41%和53.12%。KAP的内部一致性Cronbach alpha值分别为0.61、0.60和0.70。
结论
最终问卷适用于测量马来人群中与结直肠癌相关KAP。
