目的：醫學中心面臨五大科醫師招募不足或冷熱門科招募不均的問題，本研究藉探討個人特質對於選擇專科的影響，希對醫院擇才及醫學生生涯規劃有助益。方法：以南部某醫學中心2014、2015年畢業後一般醫學訓練醫師為對象，填寫愛德華斯個人興趣量表（Edwards Personal Preference Schedule；EPPS），回收124份，而後觀察其執登專科，以STATA 14.0 進行羅吉斯回歸，探討個人特質對選擇專科的影響。結果：名次居中或「內省需求（intraception）」高的醫師會傾向選開業科，但名次中後段的男性或「改變需求（change）」高的醫師會傾向不選開業科；名次居後或「積極需求（aggression）」高的醫師傾向選外科；「表現需求（exhibition）」高的醫師傾向選兒科或急診；「自謙需求（abasement）」高者傾向選內科。結論：自謙、積極、表現、內省、改變五種心理需求會影響專科選擇；性別對專科選擇無顯著影響，但同時加上畢業名次因素，影響程度會接近顯著。

Objectives: The shortage of medical residents in traditional specialties in Taiwan has become a major issue in recent years. The purpose of the study is to investigate the impact of personality traits on the specialty choices of the first-postgraduate-year residents (PGY- 1). The results will be used to improve resident recruitment strategies and the career development of the medical graduates. Methods: The study adopted purposive sampling and Edwards Personal Preference Schedule for data collection. A total of 124 PGY-1 residents participated in the study in 2014-2015. Statistical software (STATA 14.0) was used for stepwise logistic regression to investigate the impact of personality traits on specialty choice. Results: Participants with mid-academic ranking or high-intraception scores tend to choose general practice as a career, but male participants with low-academic ranking or high-change scores do not. Participants with low-academic ranking or high-aggression scores tend to choose surgery, while participants with high-exhibition scores tend to choose pediatrics or emergency as a career. Participants with high-abasement scores tend to be internists. Conclusions: A significant difference was found among first-postgraduate-year residents choosing specialties regarding abasement, aggression, exhibition, intraception, and change. Gender is not one of the contributing factors unless the academic ranking is taken into account.
