Area of Science:

  • Epidemiology
  • Psychiatric Research
  • Public Health

Background:

  • Collecting large-scale epidemiological data is traditionally resource-intensive.
  • Previous methods for community mental health surveys were costly and time-consuming.

Purpose of the Study:

  • To outline an efficient methodology for epidemiological data collection.
  • To assess the feasibility and reliability of using portable computers for psychiatric screening in community settings.

Main Methods:

  • Utilized standard psychiatric questionnaires, including a computerized Diagnostic Interview Schedule Screening Interview.
  • Conducted interviews with 1009 South Australian subjects in their homes using portable laptop computers.
  • Employed lay interviewers with minimal supervision.

Main Results:

  • The laptop-based screening method produced prevalence estimates comparable to the established Diagnostic Interview Schedule.
  • All interviews were successfully completed by lay interviewers under minimal supervision.
  • The methodology proved to be a cost-effective and time-efficient alternative for large community samples.

Conclusions:

  • A computerized approach using portable laptops is a viable and efficient method for epidemiological data collection.
  • This technique allows for reliable psychiatric screening in community settings with lay interviewers.
  • The methodology offers a significant improvement in cost and time efficiency for large-scale health research.
