To compare the psychometric properties of 2 heart failure (HF)-specific quality of life questionnaires and the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) in patients with HF.
A methodological study based on 3-month follow-up data for evaluating psychometric properties of health-related quality of life (HRQOL) questionnaires.
Cardiac rehabilitation center at a cardiovascular research institute.
Eligible patients with HF (N=60).
Exercise training in cardiac rehabilitation.
The SF-36, the MacNew Heart Disease questionnaire, and the Minnesota Living With Heart Failure Questionnaire (MLHFQ) and New York Heart Association functional classification.
Items from the MLHFQ and the MacNew questionnaire had acceptable correlations (r>.30, P<.05). Internal consistency and test-retest reliability were adequate at ≥0.7 for the MLHFQ subscales. Correlations for the MLHFQ and the MacNew with SF-36 similar items ranged from .28 to .50 and from .26 to .60, respectively. Similar scales from the MacNew and MLHFQ showed strong correlations at baseline and follow-up, supporting the convergent validity. Improvement in HRQOL was significant for all MLHFQ subscales (P<.001) and the MacNew emotional (P<.05) and social (P<.001) subscales. The MLHFQ demonstrated the most responsiveness to changes and discriminated disease severity the best. The follow-up scores for all MLHFQ and 2 MacNew subscales were significantly greater in patients who improved compared with those who showed no change or deteriorated.
The MLHFQ was more responsive to changes of HRQOL than the MacNew questionnaire over time in patients with HF. The MacNew questionnaire was more responsive to changes than the SF-36.
比较2种心力衰竭（HF）特异性生活质量问卷与医学结局研究简明健康调查36项量表（SF-36）在HF患者中的心理测量特性。
一项基于3个月随访数据的方法学研究，用于评估健康相关生活质量（HRQOL）问卷的心理测量特性。
一家心血管研究所的心脏康复中心。
符合条件的HF患者（N = 60）。
心脏康复中的运动训练。
SF-36、MacNew心脏病问卷、明尼苏达心力衰竭生活问卷（MLHFQ）以及纽约心脏协会心功能分级。
MLHFQ和MacNew问卷的条目具有可接受的相关性（r >.30，P <.05）。MLHFQ分量表的内部一致性和重测信度在≥0.7时足够。MLHFQ和MacNew与SF-36相似条目的相关性分别为.28至.50和.26至.60。MacNew和MLHFQ的相似量表在基线和随访时显示出强相关性，支持聚合效度。所有MLHFQ分量表（P <.001）以及MacNew情绪分量表（P <.05）和社会分量表（P <.001）的HRQOL均有显著改善。MLHFQ对变化的反应性最强，对疾病严重程度的区分能力最佳。与无变化或病情恶化的患者相比，病情改善的患者所有MLHFQ和2个MacNew分量表的随访得分均显著更高。
随着时间推移，在HF患者中，MLHFQ对HRQOL变化的反应性比MacNew问卷更强。MacNew问卷对变化的反应性比SF-36更强。
