Computer Assisted Personal Interviews(CAPI) January 2008
Overview • Replacing paper/pencil questionnaires with computers (Ultra Mobile PCs, PDAs, etc) to conduct multi-topic household surveys • Increase timeliness of data collection • Increase quality through checks for consistency • Some experiences with very short surveys, but less known or documented about the implications of CAPI for LSMS surveys.
Issues: Feasibility and impact on quality • Equipment in the field: batteries/electricity, withstanding field work [weather], theft • System to Back up data • Cost • Developing appropriate software (user friendly) • Questionnaire design
Issues: Feasibility and impact on quality • Impact on how interviewers conduct interviews (probing, prompting for consistency, etc…) • Impact on how respondents respond • Ergonomic aspects to the interview • Training (recruitment) of field staff
