Development and psychometric properties of the Japanese heart failure knowledge scale.

摘要: Knowledge about their own condition is important for patients with heart failure (HF). No valid, reliable, and easily administered instrument available to measure this knowledge in clinical practice. In study, a HF scale was developed, its psychometric properties were tested. Items related extracted from relevant guidelines. Content validity of the items confirmed by an expert panel including cardiologist nurses specialized treatment care HF. A self-administered questionnaire then distributed 187 (64.0 ± 12.1 years, males 69%). 62% patients, left ventricular ejection fraction < 50% identified. Exploratory factor analysis demonstrated one-dimensionality 15-item scale. Mean score 10.7 3.0 (range, 0-15). Known-group testing revealed significant difference between newly diagnosed experienced (9.4 3.2 versus 10.8 2.9, P = 0.043). addition, scores correlated self-care assessed European Heart Failure Self-Care Behavior Scale evaluation criterion (ρ -0.304, 0.001). Cronbach's alpha 0.79, item-total correlation 0.22-0.51, thereby suggesting that reliability acceptable. Acceptable developed study. This could be useful patient
