Development and testing of the Survey of Illness Beliefs in Heart Failure tool.
This study establishes reliability and construct validity of the Survey of Illness Beliefs in Heart Failure (HF) tool, which measures the accuracy and certainty of illness beliefs people have about HF. Factor analysis produced a 2-component structure of 14 items that revealed accurate and inaccurate illness beliefs (alpha=0.87 and 0.71, respectively). Construct validity was supported with significantly greater accuracy in illness belief scores in patients evaluated or listed for heart transplantation or enrolled in an HF research study (P=.008 and .02, respectively). The reliability and validity of the tool is sufficient to support its use in clinical research.
