The feeding difficulty of 196 elderly people with dementia was investigated by means of an 11-item questionnaire administered to nursing staff. The questionnaire was analysed by means of multivariate statistics, namely factor analysis. The factor analysis demonstrated that the original items could be reduced to three factors. These three factors were named: (a) patient obstinacy or passivity; (b) nursing intervention; and (c) indicator of feeding difficulty. This quantitative analysis confirms a previous qualitative distinction between items in the questionnaire and suggests avenues of research into the relationship between the factors.
通过向护理人员发放一份包含11个条目的问卷，对196名老年痴呆患者的进食困难情况进行了调查。该问卷采用多变量统计方法即因子分析进行分析。因子分析表明，原始条目可归结为三个因子。这三个因子分别被命名为：(a)患者固执或被动；(b)护理干预；(c)进食困难指标。这种定量分析证实了之前问卷中各条目之间的定性差异，并为研究这些因子之间的关系提供了研究途径。
