Are happier people, healthier people? The relationship between perceived happiness, personal control, BMI and health preventive behaviours

Abstract

Background: This study aimed to identify the extent to which levels of happiness and self-efficacy could predict preventive health behaviours and BMI.

Method: Data was collected from 100 adults (59% female), mean age 24.75 years, measuring happiness, generalised self-efficacy beliefs, BMI, health preventive behaviours, age and gender.

Findings: Results indicate that both happiness and generalised self efficacy are salient for health preventive behaviours, explaining 20% and 26% of the variance respectively. Relationships were also noted whereby generalised self efficacy (r = −.16, p =.05) and happiness (r = -.16, p <.05) both negatively correlated with BMI. Finally, post hoc analysis revealed that there is a significant positive relationship between happiness and generalised self-efficacy (r =.57, p <.001).

Conclusion: Evidence presented here suggests that happiness and high self-efficacy beliefs can significantly enhance health protective behaviours. Moreover, those who express higher levels of happiness, also exhibit higher levels of self efficacy and have a lower BMI. Suggestions are made to tailor health promotion campaigns towards enhancing mood and personal control beliefs.
