Precollege and in-college bullying experiences and health-related quality of life among college students.

BACKGROUND AND OBJECTIVES Bullying is a commonly occurring problem behavior in youths that could lead to long-term health effects. However, the impact of school bullying experiences on health-related quality of life (HRQOL) among college students has been relatively underexplored. This study aimed to describe school bullying experiences and to empirically examine their associations with HRQOL among college students in Taiwan. METHODS Self-administered survey data (response rate 84.2%) were collected from 1452 college students in 2013 by using proportional stratified cluster sampling. Different types of bullying experiences (ie, physical, verbal, relational, and cyber) before and in college, for bullies and victims, were measured. HRQOL was assessed by the World Health Organization Quality of Life (WHOQOL-BREF) Taiwan version. RESULTS College students with cyber bullying-victimization experiences before college (β 0.060) reported significantly higher HRQOL in physical health. Regarding social relationships, those with verbal (β -0.086) and relational (β -0.056) bullying-victimization experiences, both before and in college, reported significantly lower HRQOL, whereas those with verbal (β 0.130) and relational (β 0.072) bullying-perpetration experiences in both periods reported significantly higher HRQOL. Students with cyber bullying-victimization experiences in college (β 0.068) reported significantly higher HRQOL in the environment domain. Last, the effects of verbal and relational bullying-victimization experiences on psychological HRQOL could be mediated and manifested through depression. CONCLUSIONS Various types of bullying experiences occurring before and in college were differentially associated with HRQOL in different domains. These findings underscore the importance of developing school policies and health education initiatives to prevent school bullying and ameliorate its short-term and long-term effects on HRQOL.
