To describe the distribution of a population in southern urban Adelaide in terms of readiness to screen for colorectal cancer (CRC) by Faecal Occult Blood Test (FOBT) or colonoscopy according to the stages in the Transtheoretical Model (TTM) of behaviour change and to compare the stages according to demographic variables.
A random sample of 664 South Australians aged 50 to 74 were surveyed in June 2006. Chi-squared analyses were performed to determine if statistically significant differences on demographic variables existed between participants at different stages of readiness to screen.
The precontemplation and contemplation stages when combined equated to more than half of the total respondents. Several significant differences were identified between the stages. Those in both the precontemplation and contemplation stages were older than those in the remaining stages and also had a significantly higher proportion of women when compared to the action stage. In the precontemplation stage there were significantly more respondents for whom English was a second language, and low levels of private health insurance, whereas the contemplation stage had the highest proportion of Australian-born respondents. Interestingly, levels of private health insurance were also low among those who intended to screen with colonoscopy.
The majority of the population were not found to have progressed beyond contemplation. Certain demographic characteristics varied significantly between people at different stages of readiness to screen for CRC.
根据行为改变的跨理论模型（TTM）各阶段，描述阿德莱德南部城市人群通过粪便潜血试验（FOBT）或结肠镜检查筛查结直肠癌（CRC）的意愿分布情况，并比较不同人口统计学变量阶段的情况。
2006年6月对664名年龄在50至74岁的南澳大利亚人进行了随机抽样调查。进行卡方分析以确定在筛查意愿不同阶段的参与者之间在人口统计学变量上是否存在统计学显著差异。
未考虑阶段和考虑阶段合并起来占总受访者的一半以上。各阶段之间发现了几个显著差异。未考虑阶段和考虑阶段的受访者比其他阶段的受访者年龄更大，与行动阶段相比，女性比例也显著更高。在未考虑阶段，英语为第二语言且私人医疗保险水平低的受访者明显更多，而考虑阶段澳大利亚出生的受访者比例最高。有趣的是，打算进行结肠镜检查筛查的人群中私人医疗保险水平也较低。
发现大多数人群尚未超越考虑阶段。在筛查CRC意愿的不同阶段，人群的某些人口统计学特征存在显著差异。
