Symptom Self-Reports Are Susceptible to Misinformation

Such internalization was less clear for downgraded misinformation. There was no statistically significant relation between dissociativity and acceptance or internalization of symptom misinformation. In Experiment 2, a more subtle and implicit form of misinformation was employed.

Undergraduates (N = 50) completed a checklist of common symptoms and were provided with feedback for some symptoms (targets) misleadingly suggesting that a slight majority of their peers experienced these targets on a regular basis. Next, participants rated the checklist again. Overall, symptom ratings went down for control but not for targets symptoms.

Participants with escalated symptom ratings for targets had higher dissociativity scores than those who did not exhibit escalation. Taken together, our results suggest that upward symptom manipulations affect symptom self-reports more than downward manipulations and that dissociativity may play a role in symptom escalation when misinformation is subtle.
