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.

Computer-administered therapy for depression.

We performed a randomized controlled study to evaluate computer-based cognitive behavioral therapy in 36 patients who met Research Diagnostic Criteria for major or minor depression. Patients were randomly assigned to the computer, to a therapist, or to a control group placed on a waiting list. As determined by three measures of depression (the Beck inventory, the Hamilton rating scale, and the Symptom Checklist-90-R), both treated groups had improved significantly more than the control group at the end of the treatment period and 2 months later. The treated groups did not differ from each other at either time.

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.

Self-treatment for obsessive compulsive disorder using a manual and a computerized telephone interview: a U.S.-U.K. study.

Bt steps is a patient-centered behavioral therapy program that uses a manual and a computer-driven interactive voice response system to assess and treat obsessive compulsive disorder. This nine-step program contains a self-assessment module and a self-treatment module that provides teaching on exposure and ritual prevention. The patient reads about the steps in a manual and then uses a touch-tone telephone to contact the program, in which a recorded voice conducts the interview. Of 40 patients in an open 12-week trial in the United States and London, 35 completed the self-assessment module, and 17 completed at least two sessions of exposure and ritual prevention. The system produced statistically significant improvements on measures of obsessive compulsive disorder.
