The authors examined cognitive and psychological differences between cocaine‐ and opiate‐dependent individuals, using the Symptom Check List‐90‐Revised (SCL‐90‐R) and the Shipley Institute of Living Scale (SILS). They studied a sample of 135 cocaine‐dependent and 162 opiate‐dependent patients entering drug abuse treatment studies at the National Institute on Drug Abuse‐Addiction Research Center (NIDA‐ARC) outpatient clinic. Cocaine‐dependent patients had significantly higher estimated Wechsler Adult Intelligence Scale (WAIS‐R) IQ, vocabulary, abstraction, and total T scores, as measured by the SILS. On the SCL‐90‐R, cocaine‐dependent patients had significantly higher scores for interpersonal sensitivity, anxiety, phobic anxiety, paranoid ideation, and psychoticism; opiate‐dependent patients had higher scores for somatization. The results suggest that cocaine‐dependent patients have better cognitive function and more psychopathology than opiate‐dependent patients entering drug abuse outpatient treatment studies.
