Abstract
Purpose
No previous study has estimated the association between bullying and preference-based health-related quality of life (HRQoL) (“utility”), knowledge of which may be used for cost-effectiveness studies of interventions designed to prevent bullying. Therefore, the aim of the study was to estimate preference-based HRQoL among victims of bullying compared to non-victims.
Methods
A cross-sectional survey data collection among Swedish adolescents aged 15–17 years in the first year of upper secondary school was conducted in the city of Gothenburg in Sweden (N = 758). Preference-based HRQoL was estimated with the SF-6D. Regression analyses were conducted to adjust for some individual-level background variable.
Results
Mean preference-based health-related quality of life scores were 0.77 and 0.71 for non-victims and victims of bullying, respectively. The difference of 0.06 points was statistically significant (p < 0.05) and robust to inclusion of gender, age, and parental immigrant status.
Conclusions
The preference-based HRQoL estimates in this study may be used as an upper bound in economic evaluations of bullying prevention interventions, facilitating a comparison between costs and quality-adjusted life-years.
