The attitudes and desires of some families regarding having children have also shifted. To cultivate positive societal views on childbearing, there is a need for updated educational initiatives, such as a multi-theory model. Although the multi-theory model has been used in various contexts to facilitate health behavior change, with its effectiveness validated in predicting and influencing behaviors, there has been no documented use of this model in the context of fertility, either in Iran or globally. Developing fertility encouragement programs requires cultural sensitivity and attention to accepted social norms and customs, which can enhance program efficacy. We believe the Multi-Theory Model can be effective and useful in encouraging couples to increase fertility.</span></span><br> &nbsp; Models, Psychological, Behavioral symptoms, Reproductive behavior, Multi-Theory model 1 2 http://nmj.goums.ac.ir/browse.php?a_code=A-10-1466-1&slc_lang=en&sid=1 Masoumeh Abbasi Shavazi mabbasishavazi@gmail.com 100319475328460014147 100319475328460014147 No Department of Health Education and Health Promotion, School of Public Health, Shahid Sadoughi University of Medical Sciences, Yazd, Iran Manoj Sharma 100319475328460014148 100319475328460014148 No Department of Social and Behavioral Health, School of Public Health, University of Nevada (UNLV), Las Vegas, United States ;Department of Internal Medicine, Kirk Kerkorian School of Medicine at UNLV, Las Vegas, United States Tayebeh Mokhtari Sorkhani arianmokhtari2@gmail.com 100319475328460014149 100319475328460014149 Yes Department of Health Education and Health Promotion, School of Public Health, Shahid Sadoughi University of Medical Sciences, Yazd, Iran
