Abstract

Background: Health promotion among those with chronic illness has been proposed as a strategy to contain health care cost and enhance quality of life (QOL), but little research has been done in Korea on QOL focused on health promotion of patients with chronic cardiovascular disease (CCVD). Objectives: This study was designed to estimate a structural model to represent the QOL of patients with CCVD, on the basis of a literature review and Pender's health promotion model (HPM). Methods: Data were collected by questionnaire from 436 patients with CCVD in a university hospital in Seoul from August 2001 to July 2002. Data analysis included descriptive statistics and covariance structural analysis. Results: As the fit of the hypothetical model to the data was only moderate, it was modified by excluding 10 paths and including free parameters. The modified model with path showed a good fit to the empirical data (χ2 = 508.12, p = .001, GFI = .95, AGFI = .93, NFI = .98, NNFI = .98, RMSEA = .04). Health-promoting behavior (HPB) and self-efficacy were found to have a significant direct effect on QOL. Health perception, self-esteem, perceived barriers to action, and preference were found to have indirect effects on QOL. The variables of this model explain 63% of the variance in QOL. Discussion: The modified model is considered appropriate to explain and predict QOL of patients with CCVD. Therefore, it can effectively be used as a reference model for further studies and to suggest directions in nursing practice.
