| Abstract: | These studies represent the first adaptation of the MotivationalInterviewing (MI) behavior change approach in the developingworld, using health workers directly from the community. Theobjective was to compare the effectiveness of the standard practiceof health education (comparison group) to MI (experimental group)in initiating and sustaining safe water treatment and storagebehavior. Methods: focus groups and community surveys were conductedprior to health worker training. The main outcome variableswere detectable disinfectant levels in stored household water(for Field Trial 1) and disinfectant sales (for Field Trial2). Results: in Field Trial 1 (n = 185 households), a very highadherence rate was achieved (range 71.194.7%), with nostatistical differences between the groups. Field Trial 2 (n= 427 households) incorporated lessons learned from the previoustrial and resulted in much higher purchase rates of the disinfectantin the MI group, t(7) = 10.69, p < 0.001, eta2 = 0.94. Conclusion:MI intervention appears promising for public health initiativesin the developing world. Further work in this area is indicated. |
