Simulated pain on the Symptom Checklist 90-Revised.

Area of Science:

• Psychological assessment
• Clinical psychology
• Psychometrics

Background:

• Distinguishing genuine pain patients from those feigning symptoms is crucial for accurate diagnosis and treatment.
• The Symptom Checklist 90-Revised (SCL-90-R) is a widely used psychological assessment tool.

Purpose of the Study:

• To determine if the SCL-90-R can differentiate between individuals with actual pain conditions and those simulating pain.
• To evaluate the effectiveness of the SCL-90-R in detecting malingering in a pain context.

Main Methods:

• Fifty patients with pain conditions completed the SCL-90-R under standard instructions.
• Twenty healthy students were instructed to feign a pain disorder for compensation while avoiding detection, also completing the SCL-90-R.
• Statistical analysis was performed to compare the SCL-90-R responses between the two groups.

Main Results:

• Pain patients exhibited generalized elevations, with highest scores in Depression, Obsessive-Compulsive, and Somatization.
• Individuals simulating pain (simulators) scored higher than the pain group across all clinical scales.
• Simulators showed extreme elevations, with a higher likelihood of T scores exceeding 70 on clinical scales.

Conclusions:

• The SCL-90-R demonstrates potential as an aid in identifying pain simulation.
• The study suggests that the SCL-90-R's current cutoff score for detecting "faking bad" may lack specificity.
• Further research is warranted to refine the SCL-90-R's utility in detecting malingering in pain populations.
