This study had two goals: the first goal was to investigate the effects of child\'s socio-demographic variables on child anxiety and the second was to investigate the effects of child anxiety on child depression. Three-hundred-and-twenty-eight elementary students participated in this study. For socio-demographic variables, child\'s gender, child\'s grade, father\'s academic attainment, mother\'s academic attainment, mother\'s status of employment, and parents\' income levels were included. Child depression was measured using the Beck Youth Inventory-2 (BYI-2, Beck et al., 2005) and several dimensions of child anxiety (physical anxiety, overanxious, separation anxiety, test anxiety, and obsessive-compulsive dimensions) were measured using scales developed by this investigator for the purpose of this study. To address research questions, ANOVA\'s and multiple regression analyses were used. The study found that levels of child anxiety differed by child\'s gender, child\'s grade, father\'s academic attainment, mother\'s academic attainment, mother\'s status of employment, and parents\' income levels. The study also found that children\'s levels of depression were affected by their levels of physical anxiety, overanxiety, test anxiety, and obsessive-compulsive symptoms. The findings of this study will increase understanding of child anxiety and provide useful information for the treatment of children with anxiety.
