Internalizing Symptoms among Kosovar Adolescents: Pubertal Correlates in Boys and Girls

Pubertal status/stage of maturation and pubertal timing have been linked with emotional symptoms of problems among youth, particularly in vulnerable developmental contexts at risk for stress exposure. The present study tested the extent to which pubertal status/stage of maturation and pubertal timing were associated with anxious/depressed, withdrawn/depressed, and somatic complaint symptoms in Kosovar adolescents. It also tested whether sex moderated these relationships. Data were collected from N = 1,342 Kosovar adolescents (665 girls; M age = 13.26 years, SD = 1.27; 677 boys M age = 13.19 years, SD = 1.31). Regression analyses provided evidence that pubertal status/stage was positively associated with rates of anxious/depressed, withdrawn/depressed, and somatic complaint symptoms in girls, but only with withdrawn/depressed symptoms in boys. Additionally, pubertal timing was positively associated with anxious/depressed, and somatic complaint symptoms in girls; no significant links were found for boys. The present study provided evidence that advanced pubertal status/stage as well as timing is positively associated with internalizing symptoms in girls; however, only pubertal status/stage was positively associated with withdrawn/depressed symptoms in boys. The study highlights the importance of pubertal development for internalizing symptoms in a developmental context known for high stress exposure, particularly for girls.
