背景 糖尿病支持團體漸被視為為健康照顧系統的一部分，了解糖尿病支持團體的功能有助於專業人員提供必要的協助。目的 發展與測試糖尿病支持團體功能量表。方法 方便取樣589位參與糖尿病支持團體之第2型糖尿病患者填寫包含16題之糖尿病支持團體功能量表。利用探索性及驗證性因素分析檢視量表之建構效度，並與糖尿病自我效能的相關進行同時效度檢定，以內部一致性及再測信度進行量表信度分析。結果 驗證性因素分析支持16題包含4個次量表之糖尿病支持團體功能量表之建構效度。模式適配指標值分別為：卡方值／自由度比 = 2.60，比較適配指標= .94，規範適配指標=.91，漸進誤差均方根 = .07。4個次量表分別命名為增進自我照顧的執行、獲得知識及技能、心理支持及集體認同。糖尿病支持團體功能量表得分與糖尿病自我效能得分呈顯著正相關（r = .45, p ＜ .001）。總量表及4個次量表Cronbach's α值及再測信度值皆大於.70。結論／實務應用 糖尿病支持團體功能量表具良好信效度，健康專業人員可應用此量表評估糖尿病支持團體的功能，並提供必要的協助。

Background: Peer support groups for people with diabetes are increasingly considered a part of the healthcare system. Understanding the functions of peer support groups assist healthcare professionals to provide critical assistance. Purpose: The purpose of this study was to develop and assess the psychometric properties of the Functions of Diabetes Peer Support Group (F-DPSG) scale. Methods: This study used a cross-sectional design. A 16-item F-DPSG scale was developed and administered to 589 patients with Type 2 diabetes who were selected from34 diabetes peer support groups in Taiwan. Construct validity was evaluated using exploratory and confirmatory factor analyses and by examining the correlation with the score of the Chinese Diabetes Management Self-Efficacy Scale. Reliability was tested using internal consistency and test-retest reliability. Results: The 16-item F-DPSG scale, including four subscales, was supported by a second-order confirmatory factor analysis, with the following fit indices: χ^2/df ratio = 2.60, comparative fit index = .94, normed fit index = .91, and root mean square error of approximation = .07. The four subscales were ＂enhancing self-care practice,＂ ＂obtaining knowledge and skills,＂ ＂psychological support,＂ and ＂collective identification.＂ The score of the F-DPSG scale correlated significantly with the score of the Chinese Diabetes Management Self-Efficacy Scale (r = .45, p G .001). The Cronbach's α and test-retest reliability of the F-DPSG global scale and subscales were all above .70. Conclusions/Implications for Practice: The F-DPSG scale showed satisfactory reliability and validity. Healthcare providers may use the F-DPSG scale to assess the functions of peer support groups for people with diabetes and to provide necessary assistance.
