A history of childhood behavioral inhibition and enhanced response monitoring in adolescence are linked to clinical anxiety.

ABSTRACT: BACKGROUND:Behaviorally inhibited (BI) children who also exhibit enhanced response monitoring might be at particularly high risk for anxiety disorders. The current study tests the hypothesis that response monitoring, as manifest in the error-related negativity (ERN), moderates the association between BI and anxiety. METHODS:Participants (n=113; 73 male) assessed for early-childhood BI were re-assessed as adolescents with a clinical interview and a flanker paradigm that generated behavioral data and event-related potentials (ERPs). Risk for anxiety disorders in adolescents was examined as a function of childhood-BI status and adolescent performance on the flanker paradigm. RESULTS:Adolescents with childhood BI displayed ERP evidence of enhanced response monitoring, manifest as large ERNs. The ERN moderated the relationship between early BI and later clinically significant disorders. CONCLUSIONS:Physiological measures of response monitoring might moderate associations between early-childhood BI and risk for psychopathology. The subset of children with BI and enhanced response monitoring might face greater risk for later-life clinical anxiety than children with either BI or enhanced response monitoring alone.

Project description:BackgroundAnxiety symptoms gradually emerge during childhood and adolescence. Individual differences in behavioral inhibition (BI), an early-childhood temperament, may shape developmental paths through which these symptoms arise. Cross-sectional research suggests that level of early-childhood BI moderates associations between later anxiety symptoms and threat-related amygdala-prefrontal cortex (PFC) circuitry function. However, no study has characterized these associations longitudinally. Here, we tested whether level of early-childhood BI predicts distinct evolving associations between amygdala-PFC function and anxiety symptoms across development.MethodsEighty-seven children previously assessed for BI level in early childhood provided data at ages 10 and/or 13 years, consisting of assessments of anxiety and an fMRI-based dot-probe task (including threat, happy, and neutral stimuli). Using linear-mixed-effects models, we investigated longitudinal changes in associations between anxiety symptoms and threat-related amygdala-PFC connectivity, as a function of early-childhood BI.ResultsIn children with a history of high early-childhood BI, anxiety symptoms became, with age, more negatively associated with right amygdala-left dorsolateral-PFC connectivity when attention was to be maintained on threat. In contrast, with age, low-BI children showed an increasingly positive anxiety-connectivity association during the same task condition. Behaviorally, at age 10, anxiety symptoms did not relate to fluctuations in attention bias (attention bias variability, ABV) in either group; by age 13, low-BI children showed a negative anxiety-ABV association, whereas high-BI children showed a positive anxiety-ABV association.ConclusionsEarly-childhood BI levels predict distinct neurodevelopmental pathways to pediatric anxiety symptoms. These pathways involve distinct relations among brain function, behavior, and anxiety symptoms, which may inform diagnosis and treatment.

Project description:BackgroundAnxiety disorders are common psychiatric conditions affecting children and adolescents. Although cognitive behavioral therapy and selective serotonin-reuptake inhibitors have shown efficacy in treating these disorders, little is known about their relative or combined efficacy.MethodsIn this randomized, controlled trial, we assigned 488 children between the ages of 7 and 17 years who had a primary diagnosis of separation anxiety disorder, generalized anxiety disorder, or social phobia to receive 14 sessions of cognitive behavioral therapy, sertraline (at a dose of up to 200 mg per day), a combination of sertraline and cognitive behavioral therapy, or a placebo drug for 12 weeks in a 2:2:2:1 ratio. We administered categorical and dimensional ratings of anxiety severity and impairment at baseline and at weeks 4, 8, and 12.ResultsThe percentages of children who were rated as very much or much improved on the Clinician Global Impression-Improvement scale were 80.7% for combination therapy (P<0.001), 59.7% for cognitive behavioral therapy (P<0.001), and 54.9% for sertraline (P<0.001); all therapies were superior to placebo (23.7%). Combination therapy was superior to both monotherapies (P<0.001). Results on the Pediatric Anxiety Rating Scale documented a similar magnitude and pattern of response; combination therapy had a greater response than cognitive behavioral therapy, which was equivalent to sertraline, and all therapies were superior to placebo. Adverse events, including suicidal and homicidal ideation, were no more frequent in the sertraline group than in the placebo group. No child attempted suicide. There was less insomnia, fatigue, sedation, and restlessness associated with cognitive behavioral therapy than with sertraline.ConclusionsBoth cognitive behavioral therapy and sertraline reduced the severity of anxiety in children with anxiety disorders; a combination of the two therapies had a superior response rate.
