摘要
目的基于计划行为理论构建无偿献血意愿问卷,以评估普通社区居民献血意愿、探索居民献血意愿的影响因素,从而为采供血机构的无偿献血宣传招募策略的制定提供科学依据。方法采用区分度分析、逐步回归法、相关系数法、Cronbach's α法、因子分析法进行条目筛选,由保留条目形成无偿献血意愿问卷,采用Cronbach's α系数评价问卷信度,采用验证性因子分析评价问卷效度。结果无偿献血意愿问卷由9个维度、23个条目组成。总问卷的α系数为0.889,各维度的α系数为0.644～0.917。验证性因子分析显示问卷各维度拟合良好。结论无偿献血意愿问卷的构建基本符合理论构想,各条目具有良好的敏感性、独立性、代表性,问卷有较好的信效度,可以用于评估居民献血意愿。
