OBJECTIVE: 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. DESIGN: A
methodological study based on 3-month follow-up data for evaluating psychometric
properties of health-related quality of life (HRQOL) questionnaires. SETTING:
Cardiac rehabilitation center at a cardiovascular research institute.
PARTICIPANTS: Eligible patients with HF (N=60). INTERVENTIONS: Exercise training
in cardiac rehabilitation. MAIN OUTCOME MEASURES: The SF-36, the MacNew Heart
Disease questionnaire, and the Minnesota Living With Heart Failure Questionnaire
(MLHFQ) and New York Heart Association functional classification. RESULTS: 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.
CONCLUSIONS: 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.
