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

Area of Science:

• Psychology
• Clinical Psychology
• Psychotherapy Research

Background:

• Assessing treatment effectiveness relies on accurate patient recall of pre-treatment symptoms.
• Patient memory of distress may be subject to biases, potentially affecting outcome evaluations.

Purpose of the Study:

• To investigate whether psychotherapy clients accurately recall their pre-therapy distress levels.
• To explore the relationship between memory recall errors and individual psychological differences.
• To examine how distress levels at termination influence these recall biases.

Main Methods:

• Clients completed distress measures post-therapy, recalling their pre-therapy scores.
• A control group without therapy also recalled past distress.
• Correlational analyses examined links between recall accuracy, personality traits (anxiety, depression, neuroticism, ego strength), and specific memory errors.

Main Results:

• Most clients overestimated their pre-therapy distress, unlike a control group.
• Overestimation correlated with higher anxiety, depression, and neuroticism, and lower ego strength.
• Distress at termination mediated the effects of individual differences on recall errors.
• Specific memory errors (adding, exaggerating, omitting, minimizing) were linked to individual differences.

Conclusions:

• Psychotherapy clients often exhibit recall bias, overestimating past distress and creating an illusion of change.
• Individual differences in personality and psychological states influence memory accuracy for past symptoms.
• Misremembering distress may reflect and potentially contribute to psychological states and individual differences.
