Objective/Purpose: To use Protection Motivation Theory (PMT) to evaluate stakeholders' intention to adopt iodine biofortified foods as an alternative means to improve children's iodine status and overall school performance. Methods: A survey was administered with 360 parents of primary school children and 40 school heads. Protection motivation is measured through matching the cognitive processes they use to evaluate iodine deficiency (threat appraisal), as well as iodine biofortified foods to reduce the threat (coping appraisal). Data were analyzed through Robust (Cluster) regression analysis. Results: Gender had a significant effect on coping appraisal for school heads, while age, education, occupation, income, household size and knowledge were significant predictors of threat, coping appraisal and/or protection motivation intention among parents. Nevertheless, in the overall protection motivation model, only two coping factors, namely self-efficacy (parents) and response cost (school heads), influenced the intention to adopt iodine biofortified foods. Conclusion: School feeding programs incorporating iodine biofortification should strive to increase not only consumer knowledge about iodine but also its association to apparent deficiency disorders, boost self-efficacy and ensure that the costs incurred are not perceived as barriers of adoption. The insignificant threat appraisal effects lend support for targeting future communication on biofortification upon the strategies itself, rather than on the targeted micronutrient deficiency. PMT, and coping factors in particular, seem to be valuable in assessing intentions to adopt healthy foods. Nevertheless, research is needed to improve the impacts of threat appraisal factors.
