Autistic traits in adolescents in psychiatric inpatient care: Clinical and demographic characteristics and correlates.

BACKGROUND: Rates of psychiatric hospitalization among adolescents in the United States are rising, with many adolescents presenting to these settings with diverse clinical presentations, including autistic traits. To our knowledge, there has been little research identifying clinical characteristics of adolescents with autistic traits admitted to psychiatric inpatient units, which may be leveraged to improve assessment and treatment practices.

METHOD: In the current study, we examined clinical and demographic characteristics of 195 adolescents admitted to an adolescent psychiatric inpatient unit. Specifically, we investigated the prevalence of adolescents endorsing elevated autistic traits and tested associations between autistic traits, psychiatric symptoms (anxiety, depression, suicidal thoughts), and key demographic variables (age, sex, gender, sexual orientation).

RESULTS: Results show that over half of the adolescents admitted to the psychiatric inpatient unit reported elevated autistic traits on a short screening questionnaire. Higher autistic traits were significantly associated with more severe depressive symptoms, though to a small degree. Autistic traits were not associated with anxiety symptoms, suicidal thoughts, nor social disconnectedness, and did not differ by sex, gender identity, nor sexual orientation.

CONCLUSIONS: Findings highlight the challenge of diagnostic overshadowing among adolescents in crisis and the need for more rigorous measures designed for an inpatient setting to improve risk stratification, clinical assessments, intervention approaches, and discharge planning.
