This study examined the associations among perceived control over anxiety-related events, worry, and both symptoms and diagnoses of generalized anxiety disorder (GAD). The sample was comprised of 140 adolescents (60 girls) between the ages of 10 and 17 years (M[subscript age] = 14.6 years; SD = 2.25) recruited from the general community. Findings were consistent with hypotheses. Self-reported perceived control over anxiety-related events related negatively to worry as well as symptoms and diagnoses of GAD even after accounting for variance associated with age, gender, and negative affectivity. Results are discussed in terms of the theoretical implications that perceived control over anxiety-related events may have for understanding GAD symptomatology among youth.
