本研究目的在探討衛教方案對接受冠狀動脈擴張術患者的危險因素監控知識、態度及行爲之成效。採類實驗研究法，以立意取樣選取35~70歲，無心肌梗塞及施行冠狀動脈繞道手術之病史，第一次接受冠狀動脈擴張術成功的病患60位，依入院順序分派至實驗組及對照組各30人。對照組只接受常規護理，實驗組給予衛教方案（包括住院期間予冠心病防治的個別衛教及出院後三次的電話追蹤），以研究者自編之結構問卷爲評估工具，包括「危險因素監控知識量表」、「危險因素監柱態度量表」和「危險因素監控行爲量表」三量表，效度測定採用專家效度，信度係數Cronbach's α值依序爲：0.73、0.71和0.70。研究結果發現，衛教實施一個月後，實驗組對於冠心病危險因素監控知識、態度及行爲之得分增加量顯著高於對照組，實驗組的危險因素監控知識得分增加6.2分(p<0.001)、態度得分增加6.7分(p<0.001)及行爲得分增加10.5分(p<0.001)。研究結論是個別衛教合併電話追蹤對冠狀動脈擴張術患者危險因素監控知識、態度及行爲有正面影響。依據本研究結果可作爲冠狀動脈擴張術病患住院及出院衛教設計之參考。

This study examined the effects of health education program on knowledge, attitude and behavior of risk factor control for percutaneous transluminal coronary angioplasty (PTCA) patients. The research design was quasi- experimental using purposive sampling. Sixty first time PTCA inpatients, aged 35 to 70 years, were recruited and consecutively assigned to an experimental group (n=30) or a control group (n=30). Patients in the control group received routine care. Patients in the experimental group also received health education including individual education during hospitalization about coronary artery disease prevention and three telephone follow-ups post-discharge. Outcomes were measured by a structured questionnaire developed by the author. The questionnaire included a "knowledge of risk factor control" scale, an "attitude of risk factor control" scale, and a "behavior of risk factor control" scale, The validity of these scales was tested by use of an expert panel. The Cronbach's internal reliability scores were 0.73, 0.71, and 0.70, respectively. Patients in the experimental group had higher scores on knowledge, attitude, and behavior scales than the patients in the control group. On knowledge scale, the experimental group scored 6.2 points higher than control group (p<0.001). On attitude scale, the experimental group scored 6.7 points higher than control group (p<0.001). On behavior scale, the experimental group scored 10.5 points higher than control group (p<0.001). In conclusion, individual health education combined with telephone follow-ups had positive effects on knowledge, attitude, and behavior of risk factor control for patients with PTCA. The results of this study can serve as reference for designing PTCA hospital and discharge education programs.
