Relationships between children-related factors, basic psychological need satisfaction, and multiple happiness among urban empty-nesters in China: a structural equation modeling

Abstract Background Aging and empty-nesting in China are becoming more and more serious. Empty-nesters refer to older adults who were not living with their children, were living alone, or were living independently with their spouses. The mental health of empty-nesters needs timely attention. Satisfying the needs of older adults is primarily dependent on their children. Therefore, this study aimed to explore relationships between children-related factors, basic psychological need satisfaction, and multiple happiness among urban empty-nesters in China. Methods This study employs the Children-related Factors Questionnaire (CFQ), the Chinese Version of the Basic Psychological Need Satisfaction (BPNS) Scale, and the Multiple Happiness Questionnaire (MHQ) to explore children-related factors, basic psychological need satisfaction and multiple happiness of urban empty-nesters in Fuzhou, China. A total of 507 samples were recruited by cluster sampling. Results Factors that affect BPNS include physical condition, the number of children, satisfaction with children's marriage, employment and income, retirement, gender, monthly personal income, and self-care have statistical differences (P < 0.05). Factors that affect MHQ include physical condition, the number of children, satisfaction with children's marriage, employment and income, gender, monthly personal income, living status, and self-care have statistical significances (P < 0.05). Structural equation model results showed that BPNS directly impacted MHQ, and factors about children indirectly affect MHQ through BPNS. The mediating role of BPNS in the relationship between children-related factors and MHQ. Conclusion We should encourage our children to spend more time with the empty-nesters and communicate with them, which could help them relieve their negative emotions, satisfy their psychological needs, and improve their well-being.
