本研究的目的在探討門診糖尿病病人的自我效能、社會支持、居家自我照顧行為與血糖控制情況，以及與自我照顧行為有關的重要變項。樣本來自某醫學中心門診糖尿病患者共 66 名，採橫斷式調查研究法進行。的患者曾接受有關糖尿的衛生教育。（ 2 ）定期檢驗血糖及規律用藥是研究對象自我效能最高，也是最能做到的項目；飲食節制及規律運動的自我效能得分最低，也正是個案最不能做到的項目。（ 3 ）年齡、教育程度、罹患糖尿病年數、糖尿病治療方式等個人屬性會影響自我照顧行為。（ 4 ）特定的自我效能，與相對應的自我照顧行為均呈顯著正相關，這樣的結果印證了 Bandura 所言：當個人對執行某項行為的自我效能愈強，愈會去執行該項行為。（ 5 ）社會支持與自我照顧行為無顯著相關。（ 6 ）定期檢驗血糖及飲食自我照顧行為與血糖控制呈顯著正相關。（ 7 ）自我效能是預測及解釋自我照顧行為的最強變項。

　　　　　The purposes of this study were to investigate the self-efficacy,social support and self-care behaviors, and variables significantly associatedwith self-care practices. A total of 66 DM patients who attended the medicalclinic as outpatients were interviewed by a questionnaire. The cross-sectionalsurvey method was used.overweight or obese, 68.2% had other kinds of chronic diseases, 87.9% hadobtained health education about DM (2) Subjects had the highest scores inself-efficacy of glucose testing and taking medicine. Also subjects had thehighest scores in self-care behavior of glucose testing and taking medicineregularly. Subjects had the lowest scores in self-efficacy of diet control andregular exercise. Also subjects had the lowest score s in self-care behavior ofdiet control and taking exercise regularly. (3) Self-care practices were relatedto age, education, duration of DM, treatment of DM. (4) Specific items inself-efficacy were significantly correlated with corresponding items inself-care behaviors. Those results are consistent with Bandura's theory: peopletend to avoid tasks they believe exceed their capabilities, but performactivities they judge themselves capable of handling. (5) Social support had norelationship with self-car e behaviors. (6) Glucose testing and diet controlbehaviors were significantly associated with glycosylated hemoglobin (HbA 1 c)level. (7) Self-efficacy was the strongest predictor of self-care behaviors.
