目標：本研究目的為探討社區非胰島素依賴型糖尿病個案對與公衛護士互動關係感受、疾病知識和態度與自我照顧行為的相關性。方法：本研究為橫斷式研究設計，以高雄市八區衛生所列管之非胰島素依賴型糖尿病個案為對象，共計收取有效樣本143人，並利用結構式問卷收集資料，包括自我照顧行為量表、對與公衛護士互動關係感受量表、糖尿病知識量表、糖尿病態度量表。結果：個案自我照顧行為標準化得分為62.37，其中以飲食自我照顧行為得分最高，而足部護理自我照顧行為得分最低；對與公衛護士互動關係感受、疾病知識、疾病態度均與自我照顧行為呈現正相關；對與公衛護士互動關係感受、疾病知識是自我照顧行為的重要預測因子，總解釋變異量有29.00%。結論：由研究結果建議公衛護士應與管理的糖尿病個案建立良好互動關係，尤其應該鼓勵個案參與疾病的決定控制，並賦權給個案做決定，同時增強個案相關的疾病知識，以促進個案自我照顧計劃的執行和改善自我照顧行為。

　　　　　Objectives: The purpose of this study was to understand the relationships among perceptions of interactions with public health nurses (PHNs), knowledge of disease, attitude toward disease, and self-care behaviors among patients with non-insulin-dependent diabetes mellitus (NIDDM). Methods: A cross-sectional study was conducted among 143 community-based NIDDM cases that were cared for by PHNs from eight public health centers in Kaohsiung City, Taiwan. The structured questionnaire included a diabetes self-care scale, perception of interactions with PHNs scale, knowledge of DM scale, and attitude toward DM scale. Results: The results showed that the standardized score for overall self-care behaviors was 62.37. According to each subscale, the diet self-care scale had the highest standardized score, while the foot self-care scale had the lowest standardized score. The perception of interaction with PHNs, knowledge of disease, and attitude toward disease were all significantly positively correlated with self-care behaviors. The perception of interaction with PHNs and knowledge of disease were important predictors of self-care behaviors, and explained 29% of the total variance. Conclusions: According to the findings, PHNs should maintain good interactions with diabetes cases, especially encouraging clients to participate in control over their decisions. PHNs should empower clients to increase decision-making and reinforce the related disease knowledge of clients, so that the clients will comply with self-care plans and improve their overall self-care behaviors.
