Prediction of Oocyte Donation Intention using the Theory of Planned behavior among Women in Iran: cross-sectional study

Abstract

Objective. Oocyte donation is a complex and multifaceted behavior in women. TPB (Theory of Planned behavior) is a suitable model for explaining and predicting behavior in many behavioral domains. The aim of this study was to predict oocyte donation intention using the theory of planned behavior. Materials and Methods. This cross-sectional study was performed on 560 women who were covered by the comprehensive health service centers in Iran in 2022. Data were collected online using researcher-made questionnaires included oocyte donation knowledge questionnaire and oocyte donation intention questionnaire (based on the TPB constructs). The validity of the questionnaires was confirmed by face and content validity and its reliability was confirmed by Cronbach's alpha coefficient. Data were analyzed in SPSS software (version 16) using hierarchical linear regression. The statistical significance was considered as P<0.05.Results. The results showed that there was a significant positive correlation between the oocyte donation intention with all constructs of planned behavioral theory (P <0.050). Theory of Planned behavior constructs explained 57.6% of the variance of oocyte donation intention. In addition, constructs of perceived power (β = 0.561), control beliefs (β = 0.454) and normative beliefs (β = 0.525) were the strongest predictors of oocyte donation intention, respectively. Conclusions.It seems that creating a favorable condition for oocyte donation, culture building, providing comprehensive support in society, and planning and implementing educational courses according to the constructs of the theory of planned behavior can be a great step toward the elimination of oocyte deficiency and infertility problems.
