To evaluate the applicability, internal consistency and validity of the Minnesota Living with Heart Failure Questionnaire (MLHFQ) when used in primary care, compared with the Short Form-36 (SF-36) health survey.
The two questionnaires were administered to 589 patients with chronic heart failure who were registered with 97 primary care physicians. The applicability, internal consistency and validity of the MLHFQ were evaluated and comparisons were made with the SF-36.
More than 90% of patients completed the questionnaires. The percentage of uncompleted items was low. Cronbach's alpha ranged from 0.79 to 0.94 for the various MLHFQ dimensions. Exploratory factorial analysis identified two factors that explained 65.8% of the variance. Moderate to good correlations were observed between similar dimensions of the MLHFQ and SF-36 (correlation coefficient -0.43 to -0.73). There were significant associations between scores on the MLHFQ and clinical measures of disease severity.
When used in primary care, the MLHFQ had a high level of acceptability and good psychometric properties compared with the SF-36. Consequently, it would be useful for assessing health-related quality of life in patients with chronic heart failure.
评估明尼苏达州心力衰竭生活质量问卷（MLHFQ）在初级保健中的适用性、内部一致性和有效性，与 36 项简短健康调查（SF-36）相比。
对 97 名初级保健医生登记的 589 名慢性心力衰竭患者进行了这两个问卷的管理。评估了 MLHFQ 的适用性、内部一致性和有效性，并与 SF-36 进行了比较。
超过 90%的患者完成了问卷。未完成项目的百分比较低。MLHFQ 各个维度的克朗巴赫α值范围为 0.79 至 0.94。探索性因子分析确定了两个解释 65.8%方差的因素。MLHFQ 和 SF-36 相似维度之间存在中度至良好的相关性（相关系数 -0.43 至 -0.73）。MLHFQ 评分与疾病严重程度的临床测量指标之间存在显著关联。
与 SF-36 相比，MLHFQ 在初级保健中具有较高的可接受性和良好的心理测量特性。因此，它将有助于评估慢性心力衰竭患者的健康相关生活质量。
