Factors Influencing the Intention to Have Children in the Future Among Generation Z Students at a University in Phatthalung Province
Main Article Content
Abstract
Background: Thailand’s future population is expected to decline, which may impact the country's development. The birth rate depends on individuals' intentions to have children. Understanding the factors that influence this intention will be beneficial for developing effective policies to promote childbirth.
Objectives: To examine the factors and levels of factors influencing Generation Z students’ intention to have children in the future at a university in Phattalung province.
Methods: This descriptive study collected online data from 239 participants aged between 20 and 27. The instruments included a scale measuring attitude, reference group conformity, perceived behavioral control, and intention to have children, with item-total correlation indices of 0.860, 0.833, 0.867, and 0.867, respectively. The overall content validity index (CVI) was .848. The reliability of the instruments, as measured by Cronbach’s alpha coefficient, was .893. Data were analyzed using descriptive statistics and multiple regression analysis.
Results: The results showed that attitudes, support from reference groups, and perceived behavioral control were all significant predictors of the intention to have children, 21.10% (R²=0.211, F=21.008, p<.001). The factors predicting the intention to have children with statistical significance included attitudes (β=.164, p<.05), support from reference groups (β=.238, p<.01), and perceived behavioral control (β=.168, p<.05).
Conclusions: Relevant agencies can use these findings to promote childbirth intentions among Generation Z by fostering positive attitudes, encouraging support from reference groups, and enhancing perceived behavioral control to increase their intentions to have children.
