The aim of the current study was to describe participants' experiences and examine the effects of group therapy on self-esteem and state anger among the adolescent children of immigrants in the US. A quasi-experimental design and qualitative and quantitative methods were used. Group therapy was conducted for 8weeks. Thirty-three adolescents took part in the study. Quantitative results revealed that group therapy improved self-esteem (t=2.222. p<.05) but not state anger. However, qualitative results suggested that group therapy helped improve interpersonal relationships and communication skills, the forgiveness of others, and the management of anger. Furthermore, group therapy utilizing positive psychology strategies improved self-esteem, interpersonal relationships, and communication skills.
