Factors Infuencing Intention toward Iodine Receiving of Pregnancies at Antenatal care unit of Health Services in Udon Thani Province

Abstract

      The objective of this research was to study factors of psychological predictive power in the framework of the implementation of planned behaviors and expand to influencing intention toward iodine receiving of pregnancies in Udon Thani province.  A cross-sectional analytic study was used for designing this research, and a multi stage random sampling using 216 pregnancies in antenatal care units of Health  services in Udon Thani province. The self reporting questionnaire was employed to collect data during July to August  2012.  Descriptive statistics were used ,including percentage, mean and standard deviation. A Pearson’s product moment coefficient and Stepwise Multiple Linear Regression Analysis were used.

       The results of the analysis showed that the relationship between mediating factors in the theory of planned behaviors will explain the intention toward iodine receiving behavior of pregnancies. These include    perceived behavior control (r = 0.701, p-value<0.01), self-efficacy (r = 0.600, p-value<0.01), social support (r = 0.489, p-value<0.01), .attitude toward behavior (r=0.237, p-value<0.01),and perceived subjective norm (r = 0.167, p-value<0.05), The multivariate analysis found these mediating psychological factors could predict the receipt of iodine during  pregnancy by accounting for 56.4 percent (R²=0.572, R²_adj = 0.564, p< 0.001). The best predictor in the model was perceived behavioral control, and could predict  intention by accounting for 49.1 percent , and following self-efficacy by accounting for the 5.7 percent, social support for 1.5 percent, and attitude toward behavior for 0.9 percent  respectively. For other factors, those were not enough information to identify the predictive power. Thus, the practitioners could modify these mediating factors to promote the intention and could impact behavior by increasing the receipt of iodine during  pregnancy.
