RESUMO
Assessment of national children's growth has shown that a large percent of country's children are afflicted with growth failure. In recent decade, different models have been used for growth promotion, but there is yet a long way for achieving the desired state of children's growth. In this study we present the CIPP [Context, Input, Process, and Product] Evaluation Model. The present study is a community-based field trial and has been rendered on 74 mothers, with children less than three years of age. A model was designed for increasing mother's participation. On the basis of this Model, a group of volunteer mothers were instructed in the subjects of growth monitoring and child nutrition. Then, these instructed other participants [beneficiaries] in the study. For the evaluation of this model, special indices and criteria were considered. The collected data was analyzed by SPSS software and suitable statistical tests. We report in this article only the results of impact evaluation. The growth state of children was significantly improved after intervention [P<0.005]. Indices like understanding and knowing how to draw growth charts by mothers as well as other indices of child care were also improved [in the two cases, the difference was meaningful P<0.001]. Considerable improvement of growth state of the children and other considered indices shows the efficacy of this Model. Systemic approach and the capability of step by step evaluation are other characteristics of the Model. As the present Model is designed on the basis of cultural and social background of the country and in accordance with its Health System, it can be also used in other regions and for development of other Health Services
