目的：文獻發現，自殺個案生前多曾求助醫療，且求助基層醫師多於精神科醫師。本研究的目的，在了解基層醫師對自殺防治的經驗、知識、態度與信心。方法：本研究為橫切面之問卷調查，選取台中縣、市的基層醫師為樣本。利用「基層醫師對自殺防治之經驗、知識、態度與信心問卷」，建立問卷的信效度後，郵寄給台中縣市所有開業的基層醫師（內科、小兒科、一般科與家醫科）(N=819)。結果：總回收率達34%。家醫科醫師較非家醫科醫師，在討論自殺(61%vs. .44%, ,p<0.05)、開立(76% %vs. .65%, ,p<0.05) )及進用(68% %vs. .56%, ,p<0.05) )抗憂鬱劑上皆較有經驗，可是反而較少轉介自殺傾向患者看精神科(56% %vs. .72%, ,p<0.01)。家醫科醫師與非家醫科醫師，同樣存有許多錯誤的知識，並且在態度、信心與參與自殺防治網絡的意願上，兩者皆未達顯著差異。結論：本結論建議所有的基層醫師，皆同樣需要接受憂鬱症及抗憂鬱劑的認識、自殺防治的處理等相關課程，以強化處理能力，建構自殺防治網絡。

Objectives: This study assessed general practitioners (GPs) experiences, knowledge, attitudes, and confidence about suicide prevention. Methods: A Suicide Prevention Experiences, Knowledge, Attiudes, and Confidence Questionnaire was constructed and administered to all the GPs (internal medicine, pedatrics, general medicine , and family medicine) in Taichung City and Taichung County (n=819), Results: A total fo 279 GPs completed the questionnaire resulting in a complete response rate of 34%. Family physicians had more experiences in discussing suicide(61% vs. 44%, p<0.05), prescribing (76% vs. 65%, p<0.05) and administering(68% vs. 56%, p<0.05) antidepressants than non-family physicians, but fewer referred patients at risk of suicide compared to psychiatrists(56% vs. 72%, p<0.01). Both of types of physicians had inadequate knowledge and low confidence about suicide prevention. Their attitudes and willingness to participate in the suicide prevention network also showed no significant difference. Conclusion: Family physicians had omre experience with suicide prevention than non-family physicians, but knowledge, attitudes, and confidence about suicide prevention showed no significant difference between the two groups, These results suggest the need for all GPs to complete training programs about depression, use of antidepressants, and suicide prevention to improve their knowledge and capability in the managing of patients with depression and risk of suicide.
