Although stimulants improve the social behaviors of hyperactive children, analogous changes in peer status have not been previously demonstrated. We compared peer appraisals of hyperactive boys (N = 25) after placebo, 0.3 mg/kg, and 0.6 mg/kg methylphenidate (Ritalin).

As a partial agonist buprenorphine may be expected to produce smaller changes, but the nature and magnitude of these changes have only been described for single doses. In the present study opioid effects and withdrawal(More)

Although brief intervention (BI) for alcohol and other drug problems has been associated with decreased levels of self-reported substance use, there is little information in the literature as to whether individuals with co-occurring hazardous substance use and mental illness would benefit from BI to the same extent as those without mental illness, despite(More)
BACKGROUND Although brief intervention (BI) for alcohol and other drug problems has been associated with subsequent decreased levels of self-reported substance use, there is little information in the extant literature as to whether individuals with co-occurring hazardous substance use and mental illness would benefit from BI to the same extent as those(More)
