This study examined the relationship between how adolescents perceived parenting behaviours and adolescent Generalized Anxiety Disorder (GAD) symptom scores. The 1,106 junior high and high school students (12-19 years old; 49.6% males and 50.4% females) completed questionnaires regarding their perception of parenting behaviours and self-rated symptoms of GAD. The findings of this study demonstrate that adolescent perceptions of parental alienation and rejection are strongly associated with adolescent GAD symptom scores. Additionally, mid-adolescence females perceive more parental alienation in relation to their GAD symptom scores than both early and mid-adolescent males. And early adolescent males perceive more parental rejection in relation to their GAD symptom scores than mid-adolescent males.
