Intellectual functioning in a sample of institutionalized narcotic addicts.
The Shipley-Hartford scales were given to 1,980 institutionalized addicts. Overall, results showed that addict IQs are about normal. Of all demographic variables analyzed, only education explained an appreciable proportion of the variance in scores (12%). There were indications that a relatively high number of addicts may have some intellectual impairment (41%). The latter results await further verification.
