An Assessment of the KDICP and MDICP Data Quality

This paper evaluates the quality of the data collected as part of the Kenya and Malawi Diffusion and Ideational Change Projects, two longitudinal household surveys that examine the role of social networks in influencing attitudes and behavior regarding family size, family planning, and HIV/AIDS in, respectively, rural Kenya and Malawi. We investigate three sources of non-sampling error: interviewer effects, response reliability and sample attrition, highlighting the interaction between them, and paying particular attention to their implications for AIDS-related behavioral research.
