A Voice-Based Computer Interview for Drug Dependence

The Recovery Attitudes and Treatment Evaluator (RAATE), via 94 true/false questions, assesses resistance and obstacles to chemical dependence treatment. We computerized the RAATE to offer questions via digitized human voice and to recognize patient responses spoken into the computer's microphone. Sixty-eight consecutive adults seeking addictions treatment were randomized to one of four formats. The voice-input/voice-output version yielded the shortest mean duration of administration. Patients reported high satisfaction ratings and confidence that their answers were accurate. They perceived their responses to be useful in treatment planning. Group mean ratings did not significantly differ by version. There was a statistical trend in which the voice-based versions reduced the intragroup variability on test duration and patient confidence. Computerized voice-interactive interviewing may shorten test durations, increase the uniformity of administration, increase access for the vision-impaired, and increase the data entry efficiency and accuracy. The method provides a consistent, controlled, and nonjudgmental interview interaction.
