Outline
To construct a structural equation model to explore the pathways of factors influencing fertility behavior among nulliparous couples of reproductive ages, providing direction for medical interventions aimed at fertility pathways.
A cross-sectional study was conducted using convenience sampling, selecting 400 nulliparous couples of reproductive ages from the permanent residents of Chengde city, Hebei Province. Data were collected through general demographic questionnaires, the Childbirth Fear Scale, the Social Support Rating Scale, the Fertility Motivation Questionnaire, and the Fertility Intention-Behavior Questionnaire. Path analysis and mediation effect testing were performed using structural equation modeling.
The constructed structural equation model demonstrated good overall fit. Childbirth fear negatively predicted fertility motivation, intention, and behavior (β values of -0.245, -0.120, and -0.123, respectively), while social support positively predicted fertility motivation, intention, and behavior (β values of 0.247, 0.145, and 0.149, respectively). Fertility motivation positively predicted fertility intention (β value of 0.816), and fertility intention positively predicted fertility behavior (β value of 0.760).
Childbirth fear and social support among nulliparous couples of reproductive ages can indirectly influence fertility behavior through fertility motivation and intention. Medical institutions should strengthen collaboration with community efforts to develop targeted intervention measures that alleviate childbirth concerns among the reproductive population and promote positive fertility behaviors.
