The aim of this study was to assess the acceptability, validity and reliability of the Short Form 36 quality of life questionnaire in 166 adult patients following discharge from a general intensive care unit. Reliability was quantified by measuring internal consistency using correlation among items and Cronbach's alpha coefficient. Reliability coefficients were calculated from two-way analysis of variance. Construct validity was tested by examining differences in scores between sex and age groups. Content validity was reflected by the spread of dimension scores. Acceptability to patients appeared reasonable, although considerable nursing time was required to administer the questionnaire. The measures of reliability exceeded recognised statistical standards in all but two instances. Construct validity was confirmed by lower scores being reported by women and older age groups. The scores of six of the eight dimensions were spread throughout the entire range of possible scores suggesting acceptable content validity.
本研究的目的是评估166名成年患者从综合重症监护病房出院后，简短健康调查问卷36项版本（Short Form 36）生活质量问卷的可接受性、有效性和可靠性。通过测量各项目之间的相关性以及Cronbach's α系数来量化内部一致性，以此评估可靠性。可靠性系数通过双向方差分析计算得出。通过检查性别和年龄组之间得分的差异来检验结构效度。维度得分的分布反映了内容效度。尽管发放问卷需要大量护理时间，但患者的接受度似乎合理。除两例情况外，所有可靠性测量均超过公认的统计标准。女性和老年组报告的得分较低，证实了结构效度。八个维度中的六个维度的得分分布在整个可能得分范围内，表明内容效度可接受。
