摘要

研究目的：年輕女性是罹患飲食障礙的高風險群，而衝動性格對於暴食及清除行為發展具有獨特重要性。有鑒於衝動性格與暴食及清除行為的關聯在過去研究中呈現分歧，本研究之衝動性格建構使用UPPS模式(Whiteside & Lynam, 2001)，將迫切、追求刺激、草率粗心和容易放棄四種衝動特質作為預測暴食及清除行為的前置因子，透過危險行為的動機觀點(Cooper, Agocha, & Sheldon, 2000)探討衝動性格對於暴食及清除行為的影響。

研究方法：本研究採橫斷式研究設計，以中壢地區大學女生為主要研究對象，透過團體施測方式收集資料，填寫問卷包含兩份量表：UPPS衝動行為量表和中文版暴食問卷，以及人口統計資料。統計方法採用項目分析和因素分析檢驗UPPS衝動行為量表之品質，皮爾森積差相關與階層迴歸分析則用以檢驗本研究假設之關聯性。

研究結果：1. 迫切和追求刺激特質與暴食行為有顯著正相關，草率粗心和容易放棄特質與暴食行為則無顯著關聯。迫切特質最能預測暴食行為，其次為草率粗心特質。2. 迫切特質與清除行為呈顯著正相關，追求刺激、草率粗心和容易放棄特質與清除行為則無顯著關聯。本研究結果指出迫切特質，即「處於負向情緒狀態時，經驗到強烈衝動」的性格傾向，是暴食及清除行為的重要危險因子。

討論：瞭解目前國內年輕女性的暴食及清除行為情形，並透過危險行為的動機模式觀點，釐清不同衝動性格特質對於暴食及清除行為的影響。校園預防和臨床實務評估「衝動性格」為暴食及清除行為的危險因子時，應強調衝動性格中「迫切」特質對於暴食及清除行為的影響。未來研究須進一步澄清草率粗心特質在暴食行為中的角色。

Objective: Young female are at high risk of eating disorder, and impulsive personality has its specific significance in the development of binge eating and purging behaviors. Considering inconsistent association of impulsive personality traits with binge eating and purging behaviors in past researches, this study use UPPS model(Whiteside & Lynam, 2001) as impulsive personality constructs, and urgency, sensation seeking, (lack of) premeditation, and (lack of) perseverance were used to be predisposing factor to predict binge eating and purging behaviors, and based on the motivational perspective on risky behaviors(Cooper, Agocha, & Sheldon, 2000), to explore the influence of impulsive personality on binge eating and purging behaviors.

Method: This study used cross sectional design, the main subjects were female undergraduate students in Chung-Li, all subjects individually completed the measures in small group sessions, including two self-report questionnaires: UPPS impulsive behavior scale and Bulimic Investigatory Test, Edinburgh(BITE), as well as demographic details. Item analysis and factor analysis were conducted to examine the UPPS impulsive behavior scale, Pearson product-moment correlation and a series of hierarchical regression analysis were conducted to examine the conceptual association of this study.

Results: 1. Urgency and sensation seeking were significantly positive associated with binge eating, (lack of) premeditation and (lack of) perseverance were not significantly associated with binge eating. Urgency was the strongest predictor of binge eating, and then (lack of) premeditation. 2. Urgency was significantly positive associated with purging behaviors, sensation seeking, (lack of) premeditation and (lack of) perseverance were not significantly associated with purging behaviors. Results is suggested that urgency, the “tendency to experience strong impulses, frequently under conditions of negative affect” was the significant risk factor for binge eating and purging behaviors.

Discussion: Understanding the incidence of binge eating and purging behaviors among young female population in Taiwanese, and based on the motivational perspective on risky behaviors, clarified the impact of distinct impulsive personality traits on binge eating and purging behaviors. Both in campus prevention and clinical practices, when assessing impulsivity as a risk factor for binge eating and purging behaviors, specific attention should be paid to urgency in the impulsive personality constructs. There is a need for further research to clarify the role of (lack of) premeditation on binge eating.
