This study explores the prevalence of bullying and victimization among Cypriot adolescents diagnosed with mental health problems. Their psychosocial adjustment in relation to bullying is studied. The sample consisted of 187 adolescents (60.2% boys; M age = 13.2) and their parents. The present sample reported significantly higher rates of victimization than existing published normative values X[superscript 2] (1, N = 187) = 27.0, p < 0.001. An alarming finding was that a total of 25.8% reported to be involved in bullying. There was a significant positive correlation between bullying and emotional symptoms (r = 0.36, p < 0.001), conduct problems (r = 0.35, p < 0.001), hyperactivity (r = 0.23, p < 0.003) and peer problems (r = 0.48, p < 0.001). The study suggests that there is increased victimization and psychosocial difficulties among Cypriot clinical population in regards to bullying.
