Self-treatment of obsessive-compulsive disorder guided by manual and computer-conducted telephone interview.

While on a waiting list for treatment by therapist-guided exposure and ritual prevention (ERP), patients with obsessive-compulsive disorder (OCD) did self-treatment at home guided by a manual plus a computer-driven telephone interview system (BT STEPS). Of 21 patients who used the system for at least three weeks while on the waiting list, one improved so much that subsequent therapist-guided ERP was unnecessary. Progress of the rest with the system predicted later progress with therapist-guided ERP. Improvement after using the system was similar to that of 20 matched historical controls who had had therapist-guided ERP without the prior use of BT STEPS. Outpatient users of BT STEPS needed less subsequent clinician-guided time than did their matched controls. In this pilot study, patients with OCD improved nearly as much with home self-treatment guided by a manual plus computer, as with treatment guided by a behaviour therapist.

Home self-assessment and self-treatment of obsessive-compulsive disorder using a manual and a computer-conducted telephone interview: replication of a UK-US study.

BACKGROUND: This open study replicates and extends previous pilot work with BT STEPS, a self-therapy system to assess and treat obsessive-compulsive disorder (OCD) through exposure and ritual prevention. METHOD: 21 OCD patients entered this open trial, using a self-guiding manual and any Touch-Tone telephone to access computer-driven interviews via an Interactive Voice Response system. The patients also used the system to rate progress on rating scales. RESULTS: The results support those of the previous open study. Of the 21 patients, 16 (76%) completed self-assessment over a mean of 21 days. Of these, 10 patients (48%) went on to do 2 or more exposure and ritual prevention sessions over a mean of 64 days; they improved significantly on OCD symptoms, as much as is usual with serotonin reuptake inhibitor medication, and in mood and work/social adjustment. Improvement was predicted by baseline motivation and by rapid completion of self-assessment with BT STEPS, even though self-assessment alone was not therapeutic. CONCLUSION: The significant improvement in the intent-to-treat analysis was due to the subgroup of patients (48% of those who began BT STEPS) who went beyond self-assessment to do exposure and ritual prevention self-therapy at home guided by BT STEPS. A controlled trial is now needed.

Home self-assessment of obsessive-compulsive disorder. Use of a manual and a computer-conducted telephone interview: two UK-US studies.

BACKGROUND: Two studies tested whether subjects with obsessive-compulsive disorder could successfully use BT STEPS, a computer-aided system, to perform self-assessment for self-treatment of obsessive-compulsive disorder by exposure and ritual prevention. METHOD: Subjects were given a self-guiding manual and could use a touch-tone telephone to access computer-controlled Interactive Voice Response interviews at their convenience from home. Using the BT STEPS system, patients rated themselves and worked out a plan for individually tailored self-exposure therapy. RESULTS: Outcomes were similar in the two studies. Of the 63 subjects who used BT STEPS, 84% completed the self-assessment module. Most calls were made outside usual office hours. As expected, subjects did not improve merely by completing self-assessment. However, completion of self-assessment predicted later improvement with self-exposure therapy. CONCLUSIONS: Most subjects successfully completed self-assessment using BT STEPS from their homes. DECLARATION OF INTEREST: BT STEPS is a trademark of Pfizer, Inc. I.M.M., L.B. and J.H.G. have a financial interest in BT STEPS.

Self-administered psychotherapy for depression using a telephone-accessed computer system plus booklets: an open U.S.-U.K. study.

OBJECTIVE: To evaluate the efficacy and acceptability of a self-help program for mild-to-moderate depression that combined treatment booklets and telephone calls to a computer-aided Interactive Voice Response (IVR) system. METHOD: In an open trial, 41 patients from Boston, Massachusetts; Madison, Wisconsin; and London, England, used COPE, a 12-week self-help system for depression. COPE consisted of an introductory videotape and 9 booklets accompanied by 11 telephone calls to an IVR system that made self-help recommendations to patients based on information they entered. RESULTS: All 41 patients successfully completed the self-assessment in the booklets and telephone calls; 28 (68%) also completed the 12-week self-help program. Hamilton Rating Scale for Depression (HAM-D) and Work and Social Adjustment scores improved significantly (41% and 42% mean reduction in the intent-to-treat sample, respectively, p < .001). Eighteen (64%) of the 28 completers were considered responders on the basis of > or = 50% reduction in their HAM-D scores. There was a higher percentage of completers in the pooled U.S. sites (82% vs. 43%), and U.S. completers improved more than those in the United Kingdom (73% vs. 43% were responders). Most (68%) of the calls were made outside usual office hours, Monday-Friday, 9:00 a.m. to 5:00 p.m. Expectation of effectiveness and time spent making COPE calls (more treatment modules) correlated positively with improvement over 12 weeks. Mean call length for completers was 14 minutes. CONCLUSION: A self-help system comprised of a computer-aided telephone system and a series of booklets was used successfully by people with mild-to-moderate depression. These preliminary results are encouraging for people who cannot otherwise access ongoing, in-person therapy.

Computer-administered rating scales for social anxiety in a clinical drug trial.

Computer-administered versions of two clinician-administered symptom rating scales for social anxiety (the Liebowitz Social Anxiety Scale [LSAS] and the Brief Social Phobia Scale [BSPS]) and one paper-and-pencil scale (the Fear Questionnaire) were developed and utilized in a clinical trial for social phobia. The reliability and validity of the computer versions were examined, as were their equivalence to the traditional versions. Correlations between the computer and original versions were high at baseline, and remained high throughout the study. The internal consistency reliability of the computer scales was also high, and almost identical to the original versions. Mean score differences between computer and original versions were not significant at baseline, and no significant differences were found between computer and traditional versions on the amount of change detected from baseline to endpoint. Seventy-seven percent of subjects felt that the computer did not interfere with their visit at baseline and a plurality (36%) preferred the computer, with 30% preferring the clinician and 34% having no preference. By the end of the study, the plurality (41%) had no preference, with 27% preferring the computer and 32% preferring the clinician. Results support the use of these computer-administered symptom rating scales of social anxiety as a viable alternative to the clinician-administered versions with this subset of patients, which should offer researchers and clinicians a reliable and cost-effective method for evaluating social phobia.

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.

A computer-administered telephone interview to identify mental disorders.

CONTEXT: Common mental disorders are often not identified in primary care settings. OBJECTIVE: To evaluate the validity and clinical utility of a telephone-assisted computer-administered version of Primary Care Evaluation of Mental Disorders (PRIME-MD), a brief questionnaire and interview instrument designed to identify psychiatric disorders in primary care patients. DESIGN: Comparison of diagnoses obtained by computer over the telephone using interactive voice response (IVR) technology vs those obtained by a trained clinician over the telephone using the Structured Clinical Interview for DSM-IV [Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition] Diagnosis (SCID). A subsample also received the clinician-administered version of PRIME-MD. PATIENTS: Outpatients (N=200) from 4 primary care clinics, an eating disorders clinic, an alcohol treatment facility, psychiatric outpatients, and community controls. SETTING: Interviews conducted by telephone, except for face-to-face administration of PRIME-MD, which was conducted at either the primary care clinic or a research clinic. MEASUREMENTS AND MAIN RESULTS: Prevalence rates for any psychiatric disorder were similar between diagnoses made by the computer and those made by a mental health professional using the SCID (60.0% vs 58.5%). Prevalence rates for individual diagnoses were generally similar across versions. However, primary care patients reported twice as much alcohol abuse on the computer (15.0%) as on either the SCID (7.5%) or the clinician-administered PRIME-MD (7.5%). Using the SCID as the criterion, both the computer- and clinician-administered versions of PRIME-MD demonstrated high and roughly equivalent levels of sensitivity and specificity. Overall agreement (K) for any diagnosis was 0.67 for the computer-administered PRIME-MD and 0.70 for the clinician-administered PRIME-MD. CONCLUSIONS: The computer-administered PRIME-MD appears to be a valid instrument for assessing psychopathology in primary care patients. Interactive voice response technology allows for increased availability, and provides primary care physicians with information that will increase the quality of patient care without additional physician time and at minimal expense.

Rural-urban differences in psychiatric status and functioning among clients with severe mental illness.

Studies of clients with severe mental illness (SMI) typically focus on individuals in larger urban areas. Less is known about clients in rural and smaller urban areas. Here we compare the psychiatric status, home and community activities of daily living, and social and vocational functioning of 1600 adult clients with SMI from 18 small-city and rural Wisconsin counties. Rural clients are less likely to have a diagnosis of schizophrenia or organic brain syndrome; have higher levels of general pathology, including more belligerent, bizarre, nervous, and depressive behaviors; and engage in fewer vocational activities than urban clients.

Computerized screening for psychiatric disorders in an outpatient community mental health clinic.

OBJECTIVE: This study examined the validity and utility of two types of computer-administered versions of a screening interview, PRIME-MD (Primary Care Evaluation of Mental Disorders), in a mental health setting: one administered by desktop computer and one by computer using a touch-tone telephone and interactive voice response (IVR) technology. METHODS: Fifty-one outpatients at a community mental health clinic were given both IVR and desktop PRIME-MD and the Structured Clinical Interview for DSM-IV (SCID-IV), which was administered by a clinician, in a counterbalanced order. Diagnoses were also obtained from charts. RESULTS: Prevalence rates found by both computer interviews were similar to those obtained by the SCID-IV for the presence of any diagnosis, any affective disorder, and any anxiety disorder. Prevalence rates for specific diagnoses were also similar to those found by the SCID-IV except for dysthymia, obsessive-compulsive disorder, and panic disorder; the first two conditions were found to be more prevalent by the computer, and panic disorder was more prevalent by the SCID. Compared with the prevalence rates in the charts, the rates found by the computer were higher for anxiety disorders, particularly for obsessive-compulsive disorder and social phobia. Using the SCID-IV as the criterion, both computer-administered versions of PRIME-MD had high sensitivity, specificity, and positive predictive value for most diagnoses. No significant difference was found in how well patients liked each form of interview. CONCLUSIONS: Results support the validity and utility of both desktop and IVR PRIME-MD for gathering information from mental health patients about certain diagnoses.

Sociodemographic characteristics of severely mentally ill clients in rural and urban counties.

Sociodemographic differences between rural and urban clients with severe mental illness (SMI) are explored using approaches which extend research in this area beyond limitations found in the few existing studies. Sixteen hundred adult clients from 18 Wisconsin counties are classified according to the degree of rurality of their counties of residence, using two definitions: a dichotomous metropolitan-non-metropolitan grouping and population density. There are significant differences between rural and urban clients for age, gender, and marital status, but not education or income. Young (18-35 years), unmarried males are more likely to live in more densely populated counties. Older (65 and older) women who are currently or previously married are more likely to live in less densely populated counties.
