Introduction Adolescence is a transitional condition from childhood to adulthood in which growth is needed. If teens do not grow as needed, they can feel disappointed, lose respect for them- selves, and assume themselves cowardly. These feelings can lead to depression 1 . 'epression is deﾀned as a disruption of psychology in which a great deal of negative feeling occurs within two weeks 2 . The symptoms of depression based on the DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) are fatigue, loss of concentration, decreased interest and excitement, reduction of self-esteem and self- conﾀdence, reduction of mood through the day, ideas of sui- cide, suicide attempts, or plans for suicide 3 . The Anxiety and Depression Association of America in Sa- dock et al 4 said that 18% of the population of 40 million people felt depression below the age of 13, and 5.6% be- tween age 13-18 5 . 3revalence of depression in Indonesiaｷ s population of 14 million was 6% for ages 15 and over, with 2.7% of them in Bengkulu province alone 6 . Efforts have been made by the government to combat depression in teens through the programs of Usaha Kesehat- an Sekolah (UKS) and Pusat Informasi dan Konsultasi Remaj a (PIKR) at school, but those programs are not optimized. They focus on behavioral counseling for the teens. There is no mention of interventions for depression. Puskesmas has a program called Program Kesehatan Peduli Remaj a (PKPR), but it only treats drug abuse (NAPZA). Because of this focus, Abstract Obj ect ive: The research identi ﾀed the inﾁuence of assertiveness training against teenage de- pression in high scholars in Kepahiang Regency, Bengkulu, Indonesia. Met hod: This study used a quasi-experiment approach with pre-test and post-test design and a control group. Eighty students were engaged through simple random sampling. Resul t s: The study found the frequency of depression in teenagers and considered the effect of assertiveness training. 14.10 teens were counted as depressed before assertiveness training provision, while the post-training average was 7.98 (p = .000). Assertiveness training had a sig- ni ﾀcant effect on the prevalence of depression in the intervention group. Conclusions: The study recommends schools to cooperate with health services to increase men- tal health programs such as building peer groups, delivering assertiveness training, and teaching stress management to prevent depression in teenagers. © 2018 Elsevier España, S.L.U.
