Basic Needs Satisfaction and Perceived Happiness:

This study investigates the association between basic needs satisfaction and perceived happiness among Vietnamese individuals, focusing on the role of offspring composition and multigenerational household arrangements.Participants included 465 Vietnamese citizens who were either married, divorced, widowed or cohabiting without formal marriage, with an average age of 39.8 years (SD = 9.7).Data were collected using the 21-item basic needs satisfaction scale and the perceived happiness measure.The research results reveal that Vietnamese citizens' satisfaction with basic needs is moderate.This satisfaction has a positive relationship with perceived happiness.Individuals with two children report higher levels of basic needs satisfaction, while satisfaction declines in families with three or more children; however, perceived happiness does not differ significantly according to the number of children.The number of sons does not lead to significant differences in either basic needs satisfaction or perceived happiness; nevertheless, individuals with two daughters report greater satisfaction and happiness.Families with both sons and daughters exhibited the highest level of happiness.Moreover, individuals living in two-generation households experience higher satisfaction with basic needs than those in extended families.The findings indicate meaningful associations between family structure, satisfaction with basic needs, and perceived happiness, which may inform public discussion and future policy considerations.Encouraging mutual understanding in multigenerational families may further enhance satisfaction for all generations living in the same household.As the study was conducted in a single province, the findings should be interpreted within this specific regional context.
