The purpose of this study was to investigate the effect of cognitive-behavioral intervention on emotional-behavioral problems in bereaved adolescent girls. Being a quasi-experimental study, the research employed a pretest, posttest and follow-up (one month) design. The statistical population included bereaved high school adolescent girls in Yazd city in 2015. Of them, 30 students were selected via access sampling method, and were then randomly assigned into experimental and control groups. The measurement instrument was Goodman Strengths and Difficulties Questionnaire (Goodman, 1997). Experimental group received 8 sessions of cognitive-behavioral intervention (each a 90-minute session). The results of analysis of covariance (with SPSS15) showed that cognitive behavioral intervention had significantly reduced emotional-behavioral problems in bereaved adolescent girls both in post test and follow-up (P ≤ 0.05). Results also showed a significant difference between groups in all subscales including emotional problems, conduct problems, hyperactivity and peer problem in post test and follow-up (P ≤ 0.05).
