| Summary: | 碩士 === 中國醫藥大學 === 環境醫學研究所 === 94 === The purposes of this cross-sectional study were to investigate the one-year prevalence rates of violent behaviors and to examine the risk factors for violent behaviors among adolescents.
The target population was school youngsters aged 11 to 18 years in Taichung city and county areas. We used stratified cluster sampling method and obtained an analytical sample of 6,245. By conducting a survey with self-reported questionnaires, we collected information on the behavior outcome and its correlates including socio-demographic factors, family and social dynamic factors such as family with violence, family and teacher caring, and peer deviance, individual psychological factors such as self-esteem and impulsivity, health risk and deviant without violent behaviors, and victimization.
The results were as follows: 1) Overall, 45.5% of the students involved at least one violent behavior in the past 12 month; 2) with regard to the types of violent behaviors, the rates of verbal violence only, physical violence only, physical and verbal violence without sexual violence/harassment, physical and verbal violence with sexual violence/harassment, and sexual violence/harassment only were 8.9%, 13.5%, 17.5%, 3.9% and 1.7%, respectively; 3) the significant risk factors for having violent behaviors included age group of 13-15 years(OR=1.39), family social economic status(OR=1.44 for the medium-low level, OR=1.48 for the medium level, OR=1.33 for the high level), family with violence(OR=1.42), impulsivity(OR=1.02), peer deviance (OR=1.02), being direct victims of trauma(OR=2.54 for physical violence, OR=1.69 for accidental events, OR=2.02 for suicidal behavior), witnessing others experiencing trauma (OR=1.71 for sexual violence/harassment, OR=1.64 for accidental events ), smoking(OR=1.42), drinking(OR=1.59), chewing betel nut(OR=1.44) and deviant without violent behaviors (OR=2.11 for boys, OR=2.18 for girls).
In conclusions, the existence of the strong relative importance of being direct and indirect victims of physical violence, having deviant behaviors and suicidal behaviors suggested that the planning and implementation of the prevention and/ or intervention programs of youth violence should take these co-occurrent behavior problems into accounts.
