University students who were high versus low on breakup distress scores were given self-report measures to assess their intrusive thoughts about the romantic breakup and their somatic symptoms that followed the breakup as well as their extracurricular activities and social support that might alleviate their breakup distress. In a regression analysis, intrusive thoughts contributed to 28% of the variance on breakup distress scores, somatic symptoms added another 8%, and extracurricular activities added 2% for a total of 38% of the variance. Convergent validity for intrusive thoughts was evident by "intrusive thoughts" scales differentiating the high from the low breakup distress groups including the "Intrusive Thoughts Scale," the "Controlling Intrusive Thoughts Scale," the "Ruminative Thoughts Scale," and the "Post-Traumatic Cognitions Scale."
