This document discusses the design and development of the survey instruments for the Second Malaysian Family Life Survey (MFLS-2), which was carried out in Peninsular Malaysia in 1988-1989. It also presents the findings of debriefings with field staff during and after the fieldwork and contains the actual survey instruments (MR-107/1) and the Interviewer Instructions. This document should be useful to users of the MFLS-2 data and to those designing their own surveys in Malaysia or in other countries. The discussions regarding instrument development (i.e., why the MFLS-2 asked the questions it did) should be especially valuable to MFLS-2 users who would like to combine the MFLS-2 data with data from the First Malaysian Family Life Survey (MFLS-1) conducted in 1976-1977. The interviewer debriefings will help users assess the quality of various parts of the MFLS-2 data.
