Description: This study of men and women (N = 104) who recently experienced myocardial infarction (MI), investigated the effect of nursing intervention based on Orem's (1991) theory of nursing on nutritional self-care related to dietary fat and cholesterol. An experimental pretest-posttest control group design was used. Patients were randomly assigned to groups before being interviewed in hospital (Time 1). The treatment group completed a 3-day diet record and received a nursing intervention home visit a week after hospital discharge. In a follow-up phone call, the results of the computer analyzed diet record of fat and cholesterol content were discussed. Seven weeks later, a second home visit was made to the treated patients and an initial home visit was made to the control group for Time 2 data collection which included 3-day diet records for both groups. Measures taken at Time 1 and Time 2 included a food habits questionnaire (Kristal et al., 1990), measurement of self-care agency (SCA)with the ASA (Isenberg et al., 1987) scale, and measures of self-efficacy and social support for eating habits (Sallis et al., 1987; 1988). The nursing intervention was effective in supporting healthy low-fat eating behavior in MI patients. Treated patients reported significantly less total fat and saturated fat in their diets compared to the controls and had significantly healthier responses related to food habits. Nursing intervention influenced patients' self-care agency (SCA). Treated patients increased their SCA between Time 1 and Time 2, while controls did not. Nursing intervention lacked impact on self-efficacy for healthy eating. Relationships among concepts were investigated by examining the 104 subjects as a group. SCA and self-efficacy for eating were significantly related to measures of nutritional self-care, while social support for eating was not. Between Time 1 and Time 2, younger men and older women increased their SCA while SCA of older men and younger women decreased.
