【摘要】 目的了解计算机辅助的电话访问技术在大城市居民中开展慢性病预防控制效果评价的应用情况。方法调查现场选择北京市西城区和昌平区,调查对象为工作或生活在该区的15~69岁的北京市常住居民,调查内容是慢性病相关政策的知晓、及执行效果方面的问题,调查问卷自行设计。采用单纯随机抽样方法抽取电话号码,计算机辅助的电话访问技术收集资料,利用Excel 2007来计算电话调查的使用效果指标,通过小组座谈来调查访问员,分析调查中途拒访原因。结果电话调查共拨出93524个电话号码。调查效率、应答率,以及接受访问者的访问成功率分别为3.8%、26.2%和75.1%。造成调查效率和应答率低的原因主要为"无人接听/占线"和"开始拒访"。影响接受访问者的访问成功率的主要因素为中途拒访,而中途拒访的主要原因为问卷涉及主题较多,有些问题设置太复杂。结论该调查的调查效率和应答率不高,但接受访问者的访问成功率较高,为提高整个电话调查的效率,应采取措施着重降低"无人接听/占线"和"开始拒访"的比例。更多还原
