This study explored the nature and extent of bullying among high school students in Baguio City, Philippines. It determined the relations between parent-child attachment, parenting styles, and bullying via a quantitative survey (n = 876) and focus group discussions (n=16). Results revealed that verbal bullying/victimization is more frequent than other types. Also, more males were involved in bullying than females. Generally, being a bully, victim, or bully-victim is negatively related with secure parental attachment and positively related with insecure parental attachment. Having a permissive mother and authoritarian father predicted bullying and having an authoritarian father was related to victimization.
