Spielberger State-Trait Anxiety Inventory

Neither 10 mg nor 30 mg of oxazepam affected the reaction time tasks in the patients, whereas the controls had dose-related impairment. The memory impairing effects did not differ significantly. In contrast to the controls, the patients could not discriminate between a 10 mg and a 30 mg dose, as assessed by visual analogue scales and the Spielberger State-Trait Anxiety Inventory Version 1, which might indicate a placebo effect of 10 mg in patients. The authors concluded that additional doses of oxazepam during long-term treatment have pronounced effects, even after daily use for more than 10 years.
