Audio-CASI vs interview method of administration of an HIV/STD risk of exposure screening instrument for teenagers.

Previous research conducted to examine the implications of using audio-computerized (A-CASI) procedures to gather sensitive sexual behaviour data has provided mixed results. The purpose of this study was to assess differences in the disclosure of HIV risk behaviours between subjects interviewed face to face and subjects interviewed using A-CASI procedures. An HIV/STD risk of exposure screening instrument was administered to 265 male and female adolescents in the juvenile justice system. T-test analyses revealed that adolescents assessed using A-CASI procedures endorsed fewer items on the HIV/STD screen than those interviewed by an assessor. In addition, those in the A-CASI group endorsed fewer items with explicit sexual or drug content and fewer subtle items. Results of this study suggest that A-CASI may not be suitable for use among adolescents in the juvenile justice system when assessing undesirable and/or illegal behaviours.
