Psychiatric disorders and function in adolescents with d-transposition of the great arteries.

OBJECTIVE: To compare adolescents with d-transposition of the great arteries (d-TGA) with healthy adolescents with respect to prevalence of psychiatric disorders and global psychosocial functioning. STUDY DESIGN: Subjects, consisting of 139 adolescents with d-TGA (16.1 ± 0.5 years) and 61 healthy adolescents (15.3 ± 1.1 years) without known risk factors for brain disorders, underwent a battery of assessments, including semistructured psychiatric interviews; self-report measures of depressive, anxiety, and disruptive behavior symptoms; and brain magnetic resonance imaging. Previous cognitive functioning and parental stress assessments at age 8 as well as parental post-traumatic stress at age 16 years were explored as potential risk factors predictive of overall psychiatric functioning. RESULTS: Compared with healthy adolescents, adolescents with d-TGA had higher lifetime prevalence of structured interview-derived attention-deficit/hyperactivity disorder (19% vs 7%, P = .03), along with reduced global psychosocial functioning (80.6 ± 11.2 vs 87.2 ± 7.1, P < .001) as well as significant increases in self-reported depressive (P = .01), anxiety (P = .02), and disruptive behavior symptoms (parent P < .001 and adolescent P = .03). Nevertheless, these youth scored in the nonclinical range on all self-report measures. Level of global psychosocial functioning was positively related to cognitive functioning (P < .001) and negatively related to parental stress (P = .008). CONCLUSIONS: Although adolescents with d-TGA demonstrate significant resilience to known neuropsychological and academic deficits, they show increased rates of attention-deficit/hyperactivity disorder and reduced psychosocial functioning. Impaired cognitive functioning and parental stress at younger age emerged as significant risk factors for psychiatric impairment.
