This study provides a preliminary examination of the relationship among shame-proneness, emotions, and persistent, unwanted courting or pursuit behaviour. A total of 222 undergraduates completed a questionnaire measuring responses to the termination of a relationship or the declining of a date. The Test of Self-Conscious Affect was used to measure shame. Although shame was unrelated to types of intrusive behaviour, individuals who engaged more repetitively in covert pursuit tended to ruminate more over their love interest than did those who rarely engaged in such behaviour. Rumination was positively correlated with shame. Self-harm behaviours and harm toward others were associated with feelings of sadness and depression, and those who engaged more often in harm toward others also reported feelings of anger and jealousy. Conclusions are made regarding the function of shame and other emotions in intrusive behaviour and their potential relevance to treatment of stalkers.
