Individual differences in misremembering pre-psychotherapy distress: personality and memory distortion

In 2 studies, clients were asked, after terminating psychotherapy, to complete a measure of symptomatic distress exactly as they had in their pre-therapy assessment. Most clients overestimated their pre-therapy distress, which may lead to an illusion of positive change. A 3rd study found no overestimation of previously reported distress in a control sample. The degree of overestimation for psychotherapy clients was positively correlated with anxiety, depression, and neuroticism, and negatively correlated with ego strength, self-deception, and lying. Distress levels at termination mediated these effects of individual differences. Individual differences were also correlated with specific types of recall error, such as adding to, exaggerating, omitting, and minimizing previously reported symptoms. Misremembering prior emotions may both reflect and create individual differences.
