Influences on childhood depressive symptoms: The effects of trauma and distress tolerance across age and sex groups.

BACKGROUND:Depression affects many children and adolescents, leading to poor academic performance, impaired psychosocial functioning, and an increased frequency of suicidal behavior. Depression has also been notably associated with trauma and distress tolerance. Our study sought to understand the relationships of these variables across age and sex categories in youth and adolescents. METHODS:The current study examined data from a total of 324 participants between the ages of 7 and 17 years-old who were a part of a larger study. Data related to age, sex, depression, trauma, and distress tolerance were examined. RESULTS:A multiple regression revealed a significant interaction between age and sex on depression severity. Further, trauma and age by sex categories significantly predicted depression score, as well as distress tolerance predicting depression score. Lastly, a regression analysis, including trauma, distress tolerance, and age by sex categories were significant predictors of depression. LIMITATIONS:The results are limited by the cross-sectional design. CONCLUSION:Clinicians should consider age by sex effects when treating childhood depression. Future research should further the understanding of depression across age and sex groups, as well as among children with extensive trauma experiences. Future research should also seek to further understand the implications of distress tolerance therapy on childhood depression.
