However, non-response rates are fairly high. Few studies have investigated factors associated with response. Intolerance of uncertainty (IU) is a treatment target for anxiety and worry in neurotypical populations and has been linked to anxiety and ASD. We sought to examine whether IU affects outcomes following MCBT in 43 children, ages 8-14 years, with ASD without intellectual disability. Consistent with prior data, there was a significant reduction in parent reported anxiety following MCBT. Higher levels of pre-intervention IU predicted higher anxiety and worry pre- and post-intervention. These findings suggest that targeting IU may improve outcomes following MCBT in youth with ASD and anxiety.

A neural biomarker, the error-related negativity, predicts the first onset of generalized anxiety disorder in a large sample of adolescent females / A. MEYER in Journal of Child Psychology and Psychiatry, 59-11 (November 2018)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 59-11 (November 2018) . - p.1162-1170 Titre : A neural biomarker, the error-related negativity, predicts the first onset of generalized anxiety disorder in a large sample of adolescent females Type de document : Texte imprimé et/ou numérique Auteurs : A.

The error-related negativity (ERN) is an event-related potential elicited when people make mistakes on simple laboratory-based reaction time tasks that has been associated with risk for anxiety. This study examined whether the ERN prospectively predicted the first onset of generalized anxiety disorder (GAD) over 1.5 years in adolescent girls. METHODS: The sample included 457 girls between the ages of 13.5 and 15.5 years, with no history of GAD. At baseline, the ERN was measured using a flankers task. Psychiatric history of the adolescent and biological parent was assessed with diagnostic interviews, and the adolescent completed a self-report questionnaire regarding anxiety symptoms. Approximately 1.5 years later, adolescents completed the same interview. RESULTS: An increased neural response to errors at baseline predicted first-onset GAD over 1.5 years. The ERN was a significant predictor independent of other prominent risk factors, including baseline anxiety and depression symptoms and parental lifetime psychiatric history. Jointly the ERN and social anxiety symptoms provided the greatest power for predicting first-onset GAD. CONCLUSIONS: This study provides evidence for the utility of the ERN as a biomarker of risk for GAD during a key developmental period.

Parenting style moderates the effects of exposure to natural disaster-related stress on the neural development of reactivity to threat and reward in children / E. M. KESSEL in Development and Psychopathology, 31-4 (October 2019)

Additionally, despite evidence that stress and parenting may both influence the development of neural systems underlying reward and threat processing, few studies have brought together these areas of research. The current investigation examined the effect of parenting styles and hurricane-related stress on the development of neural reactivity to reward and threat in children. Approximately 8 months before and 9 months after Hurricane Sandy, 74 children experiencing high and low levels of hurricane-related stress completed tasks that elicited the reward positivity and error-related negativity, event-related potentials indexing sensitivity to reward and threat, respectively. At the post-Hurricane assessment, children completed a self-report questionnaire to measure promotion- and prevention-focused parenting styles. Among children exposed to high levels of hurricane-related stress, lower levels of promotion-focused, but not prevention-focused, parenting were associated with a reduced post-Sandy reward positivity. In addition, in children with high stress exposure, greater prevention-focused, but not promotion-focused, parenting was associated with a larger error-related negativity after Hurricane Sandy. These findings highlight the need to consider contextual variables such as parenting when examining how exposure to stress alters the development of neural reactivity to reward and threat in children.

The current study investigated service use, unmet needs, and obstacles to service access for a large sample of adults with ASD. After accounting for various demographic factors known to impact service usage and needs, living situation was a significant predictor of service use, needs, and obstacles to services. Adults with ASD living with family reported less service use, higher unmet need, and more obstacles to accessing services. With more than half of this adult sample living with family, results have clear public policy implications to support the increasing population of adults with ASD living with aging caregivers.
