Abstract:
The objective of this descriptive correlation research was to identify selected factors related to dietary behaviors among persons with acute coronary syndrome. A multi-stage sampling of 195 persons with acute coronary syndrome were recruited from Cardiovascular outpatient department in Chulalongkorn Memorial Hospital, Police General Hospital, and Siriraj Hospital. Data were collected using seven questionnaires for persons with acute coronary syndrome: 1) Demographic data form 2) Dietary behaviors 3) Knowledge of cardiac disease 4) The Brief Illness Perception Questionnaire 5) Motivation for Healthy Eating Scale 6) Social support and 7) Self-efficiency. All questionnaires were tested for their content validity by five experts. The CVI were 0.94, 1.0, 1.0, 0.97, 1.0 and 0.95, respectively. Reliability were .76, .80, .73, .91, .96 and .87, respectively. Data were analyzed using Pearsons product correlation coefficient statistics. The findings were presented as follow: 1. Mean score of dietary behaviors knowledge, motivation, social support and self-efficiency among persons with acute coronary syndrome were at high level (Mean = 100.98 SD = 12.39, Mean = 16.48 SD = 2.16, Mean = 76.03 SD = 8.63, Mean = 67.43 SD = 9.09 and Mean = 25.73 SD = 3.79, respectively), mean score of illness perception was at moderate level (Mean = 49.81 SD = 9.54) 2. Motivation and self-efficiency were significantly positively correlated at moderate level with dietary behaviors among persons with acute coronary syndrome at the .05 (r = .330 and .324, respectively). Illness perception was significantly positively correlated at low level with dietary behaviors among persons with acute coronary syndrome at the .05 (r = .178). Knowledge and social support were not significantly with dietary behaviors among persons with acute coronary syndrome.
