摘要

本文旨在探討衝動性測驗工具在三組性侵害加害人得分差異情況，研究對象來自某醫療機構社區處遇男性性侵害加害人99人，第1組17人（法律和醫療文件中有衝動性用詞併有精神疾病用詞者）、第2組61人（法律和醫療文件中有衝動性用詞不併有精神疾病用詞者）、第3組21人（法律和醫療文件中沒有衝動性用詞者）。心理測驗工具有巴氏衝動量表第11版、修訂版威斯康辛卡片分類測驗、史楚普叫色測驗、波特茲迷津測驗、倫敦塔、及路徑描繪測驗，統計分析包括變異數分析、共變數分析。研究發現三組性侵害加害人除了在巴氏動作衝動分量表有差異之外，其餘心理測驗並無顯著差異。排除智商與年齡干擾效果後，第1組巴氏動作衝動分量表分數仍然高於第3組，意即動作衝動分量表可以作為評估性侵害加害人高衝動性的一種方式，並建議以巴氏動作衝動分量表18分為切截分數。

The purpose of this study was to investigate differences in the impulsivity of three sexual offender groups by using various psychological tests. The participants were 99 sexual offenders who had undergone community-based treatment. The first group comprised 17 offenders with mental disorders, whose legal and medical records included words related to impulsivity. The second group comprised 61 offenders without mental disorders, whose legal and medical records included words related to impulsivity. The third group comprised 21 offenders, whose legal and medical records did not include words related to impulsivity. The measures applied were the Barratt Impulsiveness Scale 11 (BIS-11), Modified Wisconsin Card Sorting Test, Stroop color and word Test, Porteus Mazes Test, Tower of London Test, and Trail Making Test. ANOVA and ANCOVA were adopted for statistical analyses. Notably, the BIS-11 motor subscale scores differed significantly among the three groups, but no other significant differences were identified by the other psychological tests. Even after age and IQ were controlled, the BIS-11 motor subscale scores of the first group were higher than that of the third group. Based on our results, we recommend a cut-off score of 18 for the BIS- 11 motor subscale to accurately identify high impulsivity in sexual offenders.
