Abstract

Introduction: The amount of Exclusive Breastfeeding in Iran during the years 1991-2015 is estimated to be between 10%-53%, which should be promoted for the baby according to the importance of breastfeeding. In order to intervene in breastfeeding promotion in the first step, the effective factors should be determined. Due to the lack of standard and indigenous questionnaires on the determinants of effective factors on lactation, this study aimed to design and validate native instruments for measuring the factors affecting Exclusive Breastfeeding in nulliparous women of Kashmar city based on the theory of planned behavior. Materials and Methods: In this cross-sectional study, original tool was designed using the literature review and need assessment of beliefs based on the theory of planned behavior and the researcher's experience in lactation. To validate the tool, face validity (quantitative and qualitative) with the participation of 10 nursing mothers, content-related validity (by measuring the ratio of content validity and Content Validity Index) through the panel of experts with the participation of 10 experts in health education and tool design and validity Structures (through confirmatory factor analysis) were studied by selecting 156 of the survey population. The reliability of the tool was examined by internal consistency (Cronbach's alpha) and Ray-Test Test (ICC). Results: The initial questionnaire was designed with 67 items. In the face value and validity of the qualitative literature content, some questions were changed and in the face validity, 6 items were omitted due to the score of less than 1. 5. In content validity, considering the cutting point 79% to measure content validity index and cut point of. /62 for the ratio of credit, 18 items were deleted. Structural validity was performed by confirmatory factor analysis in LISREL software, which showed RMSEA = 0. 072, AGFI =. /96. 4. The Reliability of the tool was also approved using methods such as internal consistency (α = 0. 832) and its stability through retest method (ICC = 70. 38). Conclusion: The results show that a questionnaire designed to measure the effective factors on Exclusive Breastfeeding in primipara women based on the theory of planned behavior is a reliable and trustworthy tool with acceptable reliability and validity and we recommend it in related studies.
