The purpose of the study was to characterize repetitive phenomena in Williams syndrome (WS). The parents of 60 subjects with WS completed the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) or Children's Y-BOCS, the Yale Global Tic Severity Scale, the Stereotyped Behavior Scale, and the Spence Children's Anxiety Scale--Parent Version. Nineteen…

Diana Fields; Kathryn Asbury – Journal of Autism and Developmental Disorders, 2024
This study explores how capable young children are of thinking about a potential future that uses DNA screening to assess an individual's likelihood of experiencing learning or behaviour difficulties. Puppets and a scenario-based approach were used to ask children aged 4-10 (n = 165) whether they thought DNA screening might be helpful or harmful.…

Latent Class Analysis Identifies Distinctive Behavioral Subtypes in Children with Fragile X Syndrome
Walter E. Kaufmann; Melissa Raspa; Carla M. Bann; Julia M. Gable; Holly K. Harris; Dejan B. Budimirovic; Reymundo Lozano – Journal of Autism and Developmental Disorders, 2024
Fragile X syndrome (FXS) is characterized by variable neurobehavioral abnormalities, which leads to difficulties in developing and evaluating treatments and in determining accurate prognosis. We employed a pediatric cross-sectional sample (1,072 males, 338 females) from FORWARD, a clinic-based natural history study, to identify behavioral subtypes…

Royston, R.; Oliver, C.; Moss, J.; Adams, D.; Berg, K.; Burbidge, C.; Howlin, P.; Nelson, L.; Stinton, C.; Waite, J. – Journal of Autism and Developmental Disorders, 2018
This study describes the profile of repetitive behaviour in individuals with Williams syndrome, utilising cross-syndrome comparisons with people with Prader-Willi and Down syndromes. The Repetitive Behaviour Questionnaire was administered to caregivers of adults with Williams (n = 96), Prader-Willi (n = 103) and Down (n = 78) syndromes. There were…

3q29 deletion syndrome (3q29del) is associated with neuropsychiatric and neurodevelopmental phenotypes. We previously reported that graphomotor weakness is present in up to 78% of individuals with 3q29del. We have now explored nuances of the graphomotor phenotype and its association with other comorbidities in this population. Participants were…

This study was designed to increase our understanding about characteristics and the impact of sensory symptoms (SS) and signs of hyperarousal (HA) in individuals with fragile X syndrome (FXS) from childhood through early adulthood and by gender. Data derived from the Fragile X Online Registry With Accessible Research Database (FORWARD), a natural…

Gandhi, Anusha; Zhou, Dihong; Alaimo, Joseph; Chon, Edwin; Fountain, Michael D.; Elsea, Sarah H. – Journal of Autism and Developmental Disorders, 2021
Caregivers of preschool and elementary school age children with Smith-Magenis syndrome (SMS), MBD5-associated neurodevelopmental disorder (MAND), and Pitt-Hopkins syndrome (PTHS) were surveyed to assess sleep disturbance and to identify disorder-specific sleep problems. Because of overlapping features of these rare genetic neurodevelopmental…

Moskowitz, Lauren J.; Will, Elizabeth A.; Black, Conner J.; Roberts, Jane E. – Journal of Autism and Developmental Disorders, 2020
There is limited research on the trajectory of restricted and repetitive behaviors (RRBs) in fragile X syndrome (FXS), with previous studies only examining males and/or examining RRBs as a unitary construct rather than delineating subtypes of RRBs. Thus, we described the trajectory of five subtypes of RRBs in 153 males and females with FXS (aged…

Fielding-Gebhardt, Heather; Warren, Steven F.; Brady, Nancy C. – Journal of Autism and Developmental Disorders, 2020
Parenting children with neurodevelopmental disabilities is often challenging. Biological mothers of children with Fragile X Syndrome (FXS) may be susceptible to increased risk of mental health problems. This study examined the longitudinal relationships between maternal mental health, child challenging behaviors, and mother-child relationship…

Prader-Willi syndrome (PWS) is a rare genetic disorder characterised by neurodevelopmental delays, hyperphagia, difficulties with social communication and challenging behaviours. Individuals require intensive supervision from caregivers which may negatively affect caregiver quality of life. This study used data collected in the Australasian PWS…

Srivastava, Siddharth; Clark, Bennett; Landy-Schmitt, Colleen; Offermann, Elizabeth A.; Kline, Antonie D.; Wilkinson, Samuel T.; Grados, Marco A. – Journal of Autism and Developmental Disorders, 2021
Cornelia de Lange syndrome (CdLS) is associated with repetitive and self-injurious behaviors (RBs, SIB). Evaluating children with CdLS, this study: (1) characterizes the spectrum of RBs; (2) characterizes the impact and severity of RBs including SIB; (3) describes how age and adaptive functioning relate to RBs including SIB. Fifty children…

DaWalt, Leann Smith; Fielding-Gebhardt, Heather; Fleming, Kandace K.; Warren, Steven F.; Brady, Nancy – Journal of Autism and Developmental Disorders, 2022
In this study, we examined trajectories of specific domains of behavior problems (i.e., attention problems, depression/anxiety, and aggressive behavior) from age 6 to 18 in a sample of 55 children with fragile X syndrome. We also examined autism status and early parenting as predictors of subsequent behavioral trajectories. We found that attention…

Kurtz-Nelson, Evangeline C.; Tham, See Wan; Ahlers, Kaitlyn; Cho, Daniel; Wallace, Arianne S.; Eichler, Evan E.; Bernier, Raphael A.; Earl, Rachel K. – Journal of Autism and Developmental Disorders, 2021
Self-injurious behaviors (SIB) are elevated in autism spectrum disorder (ASD) and related genetic disorders, but the genetic and biological mechanisms that contribute to SIB in ASD are poorly understood. This study examined rates and predictors of SIB in 112 individuals with disruptive mutations to ASD-risk genes. Current SIB were reported in 30%…

Lambert, Joseph M.; Parikh, Naomi; Stankiewicz, Kristen C.; Houchins-Juarez, Nealetta J.; Morales, Vivian A.; Sweeney, Erin M.; Milam, Molly E. – Journal of Autism and Developmental Disorders, 2019
Challenging behaviors involving food are common for individuals with Prader-Willi syndrome (PWS) and often lead to obesity and other chronic health conditions. Efforts to decrease these behaviors, such as isolation during meals and strict monitoring of food consumption, can be stigmatizing. To decrease the food stealing of a 7 year-old girl with…
