This study tests whether ERN magnitude changes following treatment, predicts response to treatment, and varies by treatment type. METHODS: The sample included 130 youth (9-14 years): youth with an anxiety disorder (ANX; n = 100) and healthy control (HC; n = 30) youth with no lifetime DSM-IV disorders. ANX youth were randomized to either a manualized cognitive-behavior therapy (CBT) or a comparison child-centered therapy (CCT). The ERN was assessed before and after 16 sessions of treatment and within a comparable interval for HC. Subjective ratings about making errors on the task were obtained following each testing session. The ClinicalTrials.gov identifier is NCT00774150. RESULTS: The ERN was larger in ANX than HC youth but ERN magnitude did not significantly change following treatment in the ANX youth, regardless of treatment type, and baseline ERN did not predict treatment response. Post-task ratings revealed that ANX youth worried more about task performance feedback than HC. Like the ERN, mean ratings did not significantly change following treatment. However, these ratings were not correlated with ERN amplitude. CONCLUSIONS: Findings of greater ERN in pediatric anxiety disorders are replicated in a larger sample. More importantly, findings from this randomized control trial show that a larger ERN and feeling worried about performance feedback remain unchanged following treatment and are unrelated to treatment response. Such findings suggest that action monitoring systems remain overactive in anxious youth treated with psychotherapy, suggesting the need for future investigation of whether novel complimentary cognitive and emotional training programs can modify these systems would be warranted.

Vigilant attention to threat, sleep patterns, and anxiety in peripubertal youth / E. J. RICKETTS in Journal of Child Psychology and Psychiatry, 59-12 (December 2018)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 59-12 (December 2018) . - p.1309-1322 Titre : Vigilant attention to threat, sleep patterns, and anxiety in peripubertal youth Type de document : Texte imprimé et/ou numérique Auteurs : E. J. RICKETTS, Auteur ; R. B. PRICE, Auteur ; G. J. SIEGLE, Auteur ; J. S. SILK, Auteur ; E. E. FORBES, Auteur ; Cecile D. LADOUCEUR, Auteur ; A. G. HARVEY, Auteur ; N. D. RYAN, Auteur ; Ronald E. DAHL, Auteur ; D. L. MCMAKIN, Auteur Article en page(s) : p.1309-1322 Langues : Anglais (eng) Mots-clés : Sleep  adolescence  anxiety Index. décimale : PER Périodiques Résumé : BACKGROUND: Vigilant attention to threat is commonly observed in anxiety, undergoes developmental changes in early adolescence, and has been proposed to interfere with sleep initiation and maintenance. We present one of the first studies to use objective measures to examine associations between vigilant attention to threat and difficulties initiating and maintaining sleep in an early adolescent anxious sample. We also explore the moderating role of development (age, puberty) and sex. METHODS: Participants were 66 peripubertal youth (ages 9-14) with a primary anxiety disorder and 24 healthy control subjects. A dot-probe task was used to assess attentional bias to fearful relative to neutral face stimuli. Eye-tracking indexed selective attentional bias to threat, and reaction time bias indexed action readiness to threat. Sleep was assessed via actigraphy (e.g. sleep onset delay, wake after sleep onset, etc.), parent report (Children's Sleep Habits Questionnaire), and child report (Sleep Self-Report). The Pediatric Anxiety Rating Scale assessed anxiety severity. RESULTS: Eye-tracking initial threat fixation bias (beta = .33, p = .001) and threat dwell time bias (beta = .22, p = .041) were positively associated with sleep onset latency. Reaction time bias was positively associated with wake after sleep onset (beta = .24, p = .026) and parent-reported sleep disturbance (beta = .25, p = .019). Anxiety (severity, diagnosis) was not associated with these outcomes. Sex (beta = -.32, p = .036) moderated the relation between initial threat fixation bias and sleep onset latency, with a positive association for males (p = .005), but not for females (p = .289). Age and pubertal status did not moderate effects. CONCLUSIONS: Vigilant attention to threat is related to longer sleep onset and reduced sleep maintenance. These associations are not stronger in early adolescents with anxiety. Implications for early intervention or prevention that targets vigilant attention to threat to impact sleep disturbance, and vice versa, are discussed.
