Background: To better understand health-related quality of life (HRQOL) in adolescents, it is important to gain
knowledge about factors associated with HRQOL. Being involved in bullying is a significant threat to health, and social
and psychological well-being; further, such problems can last into adulthood. The aim of this study was to explore the
role of general self-efficacy (GSE) and bullying in relation to HRQOL. We specifically sought to study the prevalence of
bullying, as well as the associations between both bullying and self-efficacy and HRQOL in a sample of adolescents.
Methods: This was a cross-sectional study of 723 adolescents (12–18 years) attending schools selected using
randomized cluster sampling. HRQOL was measured using the KIDSCREEN-52, self-efficacy was measured with the GSE
scale, and bullying was measured using the two global questions from the Olweus bullying questionnaire. Multiple
regression analyses were performed to explore how being bullied, bullying, and GSE were associated with variations in
self-reported HRQOL.
Results: Of the 723 adolescents, 13% reported being bullied; there were no gender differences within this finding.
However, more boys than girls reported that they had bullied others. Both being bullied, and bullying others, were
associated with lower HRQOL; however, being bullied was associated with the lowest scores. Higher self-efficacy was
associated with better HRQOL. Self-efficacy contributed significantly to predicting variation in HRQOL.
Conclusions: Being involved in bullying, as a victim or a bully, is associated with lower HRQOL. The association
between GSE and HRQOL indicates that self-efficacy might be a resource for increasing HRQOL among adolescents.
Our findings highlight the importance of targeting self-efficacy beliefs as an intervention strategy to improve GSE and
HRQOL in adolescents involved in bullying.
