Sertraline for social phobia: a double-blind, placebo-controlled crossover study.

OBJECTIVE: The authors examined the efficacy of sertraline in the treatment of social phobia. METHOD: In a double-blind crossover study, 12 outpatients were randomly assigned to 10 weeks of sertraline (50-200 mg/day, flexible dosing) and 10 weeks of placebo. RESULTS: A statistically significant improvement in scores on the Liebowitz Social Anxiety Scale was found with sertraline but not with placebo. There was no significant difference between scores obtained with computer- and clinician-administered versions of the Liebowitz Social Anxiety Scale, and the majority of patients preferred to be interviewed by the computer. CONCLUSIONS: Sertraline seems a safe and effective treatment for social phobia, and computer administration may be a preferable mode of assessment with socially phobic patients.

Reversibility of psychiatric symptoms in a chronic solvent abuser: a case report.

The acute mental status changes associated with inhaled solvent use have been well described. The potential long-term neuropsychiatric sequelae of inhaled solvent use are not as well characterized. We present here the case of a 20-year-old male with a 7-year history of inhaled solvent (toluene) use whose neurological and psychiatric status were followed closely over a 1-month period on an inpatient psychiatric unit.

Computerized assessment of depression and anxiety over the telephone using interactive voice response.

We examined the reliability and validity of computer-administered versions of the Hamilton Depression (HAMD) and Hamilton Anxiety (HAMA) Rating Scales that were administered over the telephone using Interactive Voice Response (IVR). In two identical studies (HAMD: N = 113, HAMA: N = 74), both the IVR- and clinician-administered versions were administered in a counterbalanced order to a heterogeneous sample of subjects with psychiatric disorders and controls. Both the IVR HAMD and HAMA demonstrated adequate internal-consistency reliability (.90 and .93, respectively) and test-retest reliability (.74 and .97, respectively). The correlation between the IVR and clinician was high (HAMD = .96; HAMA = .65). The mean score difference between the IVR and clinician versions was less than one point for both the HAMD (.69 of a point) and HAMA (.60 of a point). It took subjects 12.23 minutes to complete the IVR HAMD, compared to 15.21 minutes for the clinician version; and 11.27 minutes for the IVR HAMA, compared to 15.33 minutes for the clinician (p < .001 for both comparisons). Subjects rated the clinician better in the areas of how much they liked being interviewed and how well they were able to describe their feelings. However, they were significantly more embarrassed with the clinician than with the IVR. Results support the psychometric properties of the IVR versions of the HAMD and HAMA scales. IVR technology presents new opportunities for expanding the utility of computerized clinical assessment.

Administration of the Hamilton Depression Rating Scale using interactive voice response technology.

We compared the reliability and equivalence of scores on the Hamilton rating scale for depression obtained by an interactive voice response (IVR) system and by human raters among 367 subjects 18 to 79 years old. Structured clinical interviews indicated that 93 of these subjects met the DSM-IV criteria for current major depression. We also examined short forms using the IVR data. The results obtained with the long (17-item) IVR interview correlated with those of the face-to-face interview, as did the results of the short (six- and eight-item) IVR interviews. In a random sample of 264 subjects, linear transformations of IVR results produced scores equivalent to clinical scores in the validation sample. We conclude that computerized assessment of the severity of depression by touch-tone telephone presents expanded opportunities for outcome research.
