Psychological happiness among residents of Da Nang city: An analysis of demographic influences

This study aimed to explore the psychological well-being of residents of Da Nang city, Vietnam, focusing on four key dimensions: positive emotion, negative emotion, optimism and trust, and spirituality. A convenience and snowball sampling approach was used to recruit 1790 participants from various districts in Da Nang. Participants completed a self-report questionnaire using a 5-point Likert scale to measure psychological happiness. The data were analyzed using descriptive statistics, t tests, and ANOVA. The findings indicate high levels of positive emotion, optimism and trust, and spirituality, with moderate levels of negative emotions among participants. No significant gender differences were found in psychological happiness across all dimensions. However, age significantly influenced positive emotions, with young adults (18-25 years) reporting higher levels of positive emotions than middle-aged adults (41-60 years). Education level also had a significant impact, with university graduates displaying higher levels of positive emotion, optimism and trust, and spirituality than those with lower educational attainment. The study revealed that psychological happiness in Da Nang city is influenced by age and educational attainment but not by gender. These insights suggest that interventions to promote well-being in Da Nang should be tailored to different age groups and emphasize the benefits of higher education.
