To explore the role of the thought enhancement and thought rebound effects in obsessionality, the relationship between obsessional symptomology and responding during and after the attempted suppression of unpleasant personal intrusive thoughts was examined. Ss first completed the Maudsley Obsessive Compulsive Inventory (MOCI) [Rachman and Hodgson, 1980]. Later, Ss indicated their most frequent intrusive thought and then completed a thought suppression protocol in which they first expressed, then suppressed, and, again, expressed that thought. Ss' scores on the MOCI were examined in relation to their pattern of responding in the suppression protocol to investigate whether Ss who were higher in obsessionality were more prone to enhancement and/or rebound effects with an unpleasant personal intrusive thought than Ss who were lower in obsessionality. The following results were obtained: (1) there was a positive relationship between obsessionality levels and thought enhancement for female Ss; (2) there was a negative relationship between obsessionality levels and thought enhancement for male Ss; and (3) there was no relationship between obsessionality levels and thought rebound. These findings suggest that the rebound effect is unrelated to obsessionality and that the enhancement effect relationship to obsessionality may be more complex than previously hypothesized.
为探究思维增强和思维反弹效应在强迫观念中的作用，研究了强迫症状与抑制不愉快的个人侵入性思维期间及之后的反应之间的关系。被试首先完成了莫兹利强迫观念量表（MOCI）[拉赫曼和霍奇森，1980年]。之后，被试指出他们最常出现的侵入性思维，然后完成一个思维抑制程序，在该程序中，他们先表达，然后抑制，再一次表达那个思维。根据被试在抑制程序中的反应模式，考察他们在MOCI上的得分，以研究强迫观念较强的被试与强迫观念较弱的被试相比，是否在面对不愉快的个人侵入性思维时更容易出现增强和/或反弹效应。得到了以下结果：（1）女性被试的强迫观念水平与思维增强之间存在正相关；（2）男性被试的强迫观念水平与思维增强之间存在负相关；（3）强迫观念水平与思维反弹之间不存在相关。这些发现表明，反弹效应与强迫观念无关，而且增强效应与强迫观念的关系可能比之前假设的更为复杂。
