In non-autistic populations, females are more likely to be diagnosed with anxiety and demonstrate distinct symptom trajectories across adolescence. Prior research has demonstrated diagnostic group differences in parent- and self-reported anxiety symptoms; however, it is largely unknown if and how symptoms change over puberty. We examine trajectories of anxiety symptoms for autistic and non-autistic youth over a four-year (Y1-Y4) longitudinal study. Methods Autistic (N = 140) and non-autistic (N = 104) youth (ages 10–13 years at Y1) completed the parent- and self-report versions of the Multidimensional Anxiety Scale for Children, 2nd Edition (MASC-2). Linear mixed effects models were used to examine the impact of age, sex, and diagnosis on anxiety symptoms. Results There was a significant diagnosis-sex interaction (pFDR=0.005) on the parent-report of anxiety and a main effect of age (p < 0.001). Autistic and non-autistic females showed an increase in anxiety symptoms over time; autistic males showed a slight decrease. There was a main effect of diagnosis (pFDR=0.003) on the child-report measure of anxiety symptoms; the effects of age (pFDR=0.117) and sex were not significant (pFDR=0.305). The relationship between pubertal development and anxiety symptoms differed between the subgroups. Conclusions Our main findings – that autistic youth demonstrate greater anxiety symptoms than non-autistic youth, with distinct symptom trajectories emerging in females versus males – add to the growing literature aimed at understanding the biopsychosocial factors impacting puberty and emotional functioning across adolescence.
