Because of the restricted nature of clinic systems, commercial channels and social marketing techniques are now being mobilized for family planning purposes. Market research is fundamental to the success of such programs. In addition to normal survey procedures and the limitations of analysis merely in terms of pairwise relationships, systems models are applied to the survey findings of a Kenya contraceptive social marketing experiment in order to gain insights into the enogenous and exogenous variables relating to consumer behavior using bivariate techniques. The results of such analysis on the survey findings are presented. The conclusion is drawn that model building methodologies as described for evaluating contraceptive social marketing programs do not present any significant difficulties and that it is a practical and useful technique that provides useful insights into the dynamics of adoption of socially desirable products such as contraceptives.
