Unwanted intrusive thoughts play an integral role in a number of different disorders including obsessive-compulsive disorder, posttraumatic stress disorder and substance use and abuse disorders. The objectives of this study were twofold. First, we examined intrusive thoughts and impulses in a student and incarcerated sample. Second, in an effort to better understand the non-universality of the intrusive thought experience, we hypothesized that psychopathic traits may be accounting for the 10-20% of individuals who deny the experience of intrusive thoughts. Using the methodology of Rachman, S., and de Silva, P. [(1978). Abnormal and normal obsessions. Behavior Research and Therapy, 16, 233-248] and Salkovskis, P.M., and Harrison, J. [(1984). Abnormal and normal obsessions: a replication. Behavior Research and Therapy, 22, 549-552], the frequency and content of intrusive thinking were extremely similar to the original studies for the student group. Higher levels of psychopathic traits appear to account for a lower number of intrusive thoughts and impulses within the inmate sample. Implications of the findings and directions for future research are discussed.
不必要的侵入性思维在多种不同的疾病中起着不可或缺的作用，包括强迫症、创伤后应激障碍以及物质使用和滥用障碍。本研究有两个目的。首先，我们在学生和被监禁者样本中研究了侵入性思维和冲动。其次，为了更好地理解侵入性思维体验的非普遍性，我们假设精神病态特质可能是导致10%至20%否认有侵入性思维体验的个体出现这种情况的原因。使用拉赫曼和德席尔瓦（1978年）以及索尔科夫斯基和哈里森（1984年）的方法，侵入性思维的频率和内容与学生组的原始研究极为相似。在囚犯样本中，较高水平的精神病态特质似乎导致较少的侵入性思维和冲动。本文讨论了研究结果的意义以及未来研究的方向。
