The Brief Social Phobia Scale: a psychometric evaluation.

The Brief Social Phobia Scale (BSPS) is an observer-rated scale designed to assess the characteristic symptoms of social phobia, using three subscales-fear, avoidance, and physiological arousal-which may be combined into a total score. Each of 18 BSPS items is anchored to a 5-point rating scale. Psychometric evaluation of the BSPS in a sample of 275 social-phobia patients yielded a high level of reliability and validity.

Differential liabilities of haloperidol and thioridazine for inducing apomorphine hypersensitivity.

In an animal model of tardive dyskinesia, sensitivity to apomorphine-induced stereotyped behavior reflects increased dopamine receptor activity induced by chronic neuroleptic treatment. Four groups of Sprague-Dawley rats received haloperidol (H) 0.5 mg/kg, haloperidol 0.

Chronic benztropine and haloperidol administration induce behaviorally equivalent pharmacological hypersensitivities separately but not in combination.

This study reports the pharmacologic induction of behavioral pharmacologic hypersensitivity in an animal model of tardive dyskinesia. Four groups of rats received IP injections twice daily of 2.5 mg/kg haloperidol (H), 10 mg/kg benztropine (B), 2.
