The positive deviance (PD) approach offers an alternative to needs-based approaches for development. The “traditional” application of the PD approach for childhood malnutrition involves studying children who grow well despite adversity, identifying uncommon, model practices among PD families, and designing an intervention to transfer these behaviors to the mothers of malnourished children. A common intervention for child malnutrition, the so-called “hearth,” brings mothers together to practice new feeding and caring behaviors under the encouragement of a village volunteer. Hearths probably work because they modify unmeasured behavioral determinants and unmonitored behaviors, which, in turn, result in better child growth. Some health outcomes require a better understanding of behavioral determinants and are not best served by hearth-like facilitated group skills-building. We propose testing “booster PD inquiries” during implementation to confirm behavioral determinants and efficiently focus interventions. We share early experience with the PD approach for HIV/AIDS and food security. The attributable benefit of the PD approach within a program has not been quantified, but we suspect that it is a catalyst that accelerates change through the processes of community attention getting, awareness raising, problem-solving, motivating for behavior change, advocacy, and actual adopting new behaviors. Program-learners should consider identifying and explicitly attempting to modify the determinants of critical behavior(s), even if the desired outcome is a change in health status that depends on multiple behaviors; measure and maintain program quality, especially at scale; and creatively expand and test additional roles for PD within a given program.

This study investigates the effects of a brief training programme on the communication skills of doctors in ambulatory care settings in Trinidad and Tobago. Evaluation of doctor performance is based on analysis of audiotapes of doctors with their patients during routine clinic visits and on patient satisfaction ratings. A pre-test/post-test quasi-experimental study design was used to evaluate the effects of exposure to the training programme. Doctors were assigned to groups based on voluntary participation in the programme. Audiotapes of the 15 participating doctors (nine trained and six control) with 75 patients at baseline and 71 patients at the post-training assessment were used in this analysis. The audiotapes were content-coded using the Roter Interaction Analysis System (RIAS). Doctors trained in communication skills used significantly more target skills post-training than their untrained colleagues. Trained doctors used more facilitations in their visits and more open-ended questions than other doctors. There was also a trend towards more emotional talk, and more close-ended questions. Patients of trained doctors talked more overall, gave more information to their doctors and tended to use more positive talk compared to other patients. Trained doctors were judged as sounding more interested and friendly, while patients of trained doctors were judged as sounding more dominant, responsive and friendly than patients of untrained doctors. Consistent with these communication differences, patient satisfaction tended to be higher in visits of trained doctors.
