    Emotion Dysregulation is Substantially Elevated in Autism Compared to the General Population: Impact on Psychiatric Services
    (Wiley, 2021) Conner, Caitlin M.; Golt, Josh; Shaffer, Rebecca; Righi, Giulia; Siegel, Matthew; Mazefsky, Carla A.; University of Pittsburgh; University of Alabama Tuscaloosa; Cincinnati Children's Hospital Medical Center; University of Cincinnati; Brown University; Maine Medical Center; Tufts University
    Emerging evidence suggests that emotion regulation (ER) impairment in those with ASD is associated with poor mental health. This study used the Emotion Dysregulation Inventory, a new norm-referenced ER measure with clinical cut-offs, developed and validated in ASD and non-ASD samples, to establish rates of ER impairment and understand its association with psychiatric service use in ASD. Parents of 6-17 year olds in three well-characterized samples (nationally representative US n = 1,000; community ASD n = 1,169; inpatient ASD n = 567) completed a battery of questionnaires about their child. The prevalence of ER impairment was significantly higher in the ASD groups compared to the nationally representative sample and highest in the psychiatric Inpatient ASD group. The community ASD and inpatient ASD samples were four and seven times more likely, respectively, to exceed clinical cutoffs for emotional reactivity than the general US sample. Similarly, history of psychiatric hospitalization, recent emergency services use (police contact, emergency room visits, or in-home crisis evaluations for emotional or behavioral concerns in the past 2 months), and psychotropic medication prescriptions were significantly higher in the ASD groups. ER impairment was significantly associated with all forms of psychiatric service use, after controlling for demographics (age, sex, race), co-occurring intellectual disability, and ADHD symptoms. This is the first large-scale study to document substantially higher rates of ER impairment in youth with ASD compared to the general population. The importance of ER impairment is underscored by its association with higher utilization of inpatient, emergency, and medication services in ASD, after accounting for demographics and ADHD-related symptoms. Lay Summary This study compared problems with emotion regulation in large samples of youth with and without ASD. An ASD community sample had two to four times more youth with clinically elevated regulation impairments compared to youth without ASD. Emotion regulation impairment was also related to using psychiatric hospitalizations, emergency services, and medications in the ASD group. This study suggests that screening for emotion regulation difficulties in ASD is important and treatment may have a wide ranging impact.

    Energy intake estimation from counts of chews and swallows
    (Elsevier, 2015) Fontana, Juan M.; Higgins, Janine A.; Schuckers, Stephanie C.; Bellisle, France; Pan, Zhaoxing; Melanson, Edward L.; Neuman, Michael R.; Sazonov, Edward; University of Alabama Tuscaloosa; University of Colorado Anschutz Medical Campus; Clarkson University; INRAE; Institut National de la Sante et de la Recherche Medicale (Inserm); Universite Paris 13; heSam Universite; Conservatoire National Arts & Metiers (CNAM); Children's Hospital Colorado; Michigan Technological University
    Current, validated methods for dietary assessment rely on self-report, which tends to be inaccurate, timeconsuming, and burdensome. The objective of this work was to demonstrate the suitability of estimating energy intake using individually-calibrated models based on Counts of Chews and Swallows (CCS models). In a laboratory setting, subjects consumed three identical meals (training meals) and a fourth meal with different content (validation meal). Energy intake was estimated by four different methods: weighed food records (gold standard), diet diaries, photographic food records, and CCS models. Counts of chews and swallows were measured using wearable sensors and video analysis. Results for the training meals demonstrated that CCS models presented the lowest reporting bias and a lower error as compared to diet diaries. For the validation meal, CCS models showed reporting errors that were not different from the diary or the photographic method. The increase in error for the validation meal may be attributed to differences in the physical properties of foods consumed during training and validation meals. However, this may be potentially compensated for by including correction factors into the models. This study suggests that estimation of energy intake from CCS may offer a promising alternative to overcome limitations of self-report. (C) 2014 Elsevier Ltd. All rights reserved.
