Abstract

Psychopharmacological treatments for methamphetamine (MA) dependence have questionable efficacy. Open-label risperidone was evaluated in veterans seeking MA dependence treatment. Participants (N = 11) received four weeks of risperidone. They provided weekly self-reports of substance use, urine drug screens, and adverse effects. Neuropsychological assessments and psychiatric symptomatology (Brief Symptom Inventory; BSI) were measured at baseline and follow-up. The eight completers had an average risperidone dose of 3.6 mg/day and decreased days of MA use during the trial from a mean of 13.0 (SD = 6.5) in the 30 days prior to starting risperidone to a mean of 0.125 (SD = 0.4; t = 5.7, p = .001), When measured over time, fine motor function (Grooved Peg Board Dominant Hand) was the only neuropsychological domain to improve significantly. No other domain changed significantly from baseline to follow-up among study completers. BSI data were converted to demographically corrected T-scores utilizing appropriate normative data (mean = 50, SD = 10). BSI somatization T-scores declined from a mean of 59.0 (SD = 8.4) to 51.8 (SD = 8.3; t = 2.7, p <.05), and positive symptom distress declined from a mean of 52.8 (SD =8.0) to 41.7 (SD = 8.6; t= 3.0, p <.05). Risperidone was well tolerated and associated with decreased MA use.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
