This study was conducted as a predictive examination of family conflict and parent and peer support on adolescent self-esteem, depression, and problem behaviors. The other aim of the study was to determine whether adolescent self-esteem, depression, and problem behaviors differed according
to gender. The study sample consisted of 1,734 high school students. The results support the general hypothesis that perceptions of high conflict in the family context are related to lower levels of self-esteem and higher levels of depression; and lower levels of self-esteem are related to
higher levels of depression, which are expected to lead to higher levels of involvement in problem behaviors. To increase the level of wellness in adolescents, improving friendship quality and solving parent-adolescent crises are recommended. At the same time, prevention and intervention programs
for problem behaviors and emotional problems could be beneficial for adolescents.
