"Twenty-three survivors of the Jupiter cruise ship disaster completed the Impact of Events Scale.... [The ship sank off Athens, October 1988, after a collision, and four deaths resulted.] ....greater early intrusion [of ideas, thoughts and images] was associated with later symptom scores ....other work has shown that dysfunctional thinking is activated is activated by stressful life events for those with a prior history of depression (Miranda, 1992, Cognitive Therapy & Research 16). It is suggested, therefore, that prior depressive personality might be important in moderating the relationship between early intrusion and later symptoms in so far as it is a marker of dysfunctional or negativistic thinking. ....other research has shown more guilt-provoking causal attributions to be associated with intrusion."
