Bone Mineral Density in Boys Diagnosed with Autism Spectrum Disorder: A Case-Control Study / Kelly BARNHILL in Journal of Autism and Developmental Disorders, 47-11 (November 2017)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 47-11 (November 2017) . - p.3608-3619 Titre : Bone Mineral Density in Boys Diagnosed with Autism Spectrum Disorder: A Case-Control Study Type de document : texte imprimé Auteurs : Kelly BARNHILL, Auteur ; Lucas RAMIREZ, Auteur ; Anibal GUTIERREZ, Auteur ; Wendy RICHARDSON, Auteur ; C. Nathan MARTI, Auteur ; Amy POTTS, Auteur ; Rebeca SHEARER, Auteur ; Claire SCHUTTE, Auteur ; Laura HEWITSON, Auteur Article en page(s) : p.3608-3619 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Bone mineral density  Gastrointestinal symptoms  Gluten-free/casein-free diet  Nutrition  Vitamin D Index. décimale : PER Périodiques Résumé : This study compared bone mineral density (BMD) of the spine obtained by dual-energy X-ray absorptiometry (DEXA), nutritional status, biochemical markers, and gastrointestinal (GI) symptoms in 4-8 year old boys with Autism Spectrum Disorder (ASD) with a group of age-matched, healthy boys without ASD. Boys with ASD had significantly lower spine BMD compared to controls but this was not correlated with any biochemical markers, dietary intake of calcium and vitamin D, elimination diet status, or GI symptomology. Reduced BMD in 4-8 year old boys with ASD appears to involve factors other than nutrient intake and GI status, and requires further study.

Data relating to anthropometrics, dietary intake, blood markers, gastrointestinal (GI) symptoms, sleep issues, and behavioral concerns were gathered at baseline and after 4 months of dietary intervention. The dietary intervention was well tolerated. Improvements in nutrient status, GI symptoms, and behavioral domains were reported. The use of the SCD protocol in children with ASD/FXS and GI symptoms warrants further investigation.

Criterion-related validity of the PDDBI: Comparison with the ADOS-2 / Claire SCHUTTE in Research in Autism Spectrum Disorders, 64 (August 2019)

This study examined criterion related validity of the PDDBI through comparison with the Autism Diagnostic Observation Schedule-Second Edition (ADOS-2) in 104 children ages 2–11 years. A positive relationship between the PDDBI Autism Composite and all ADOS-2 scores, as well as some subscale correlations, supported convergent validity of the PDDBI as a measure of ASD symptomatology. Additionally, a significant negative relationship between PDDBI adaptive subscales and ADOS-2 scores reinforced divergent validity. These results add to the literature on the validity of the PDDBI as a measure of ASD symptoms.

PDDBI and ADOS-2 autism severity scores are correlated but yield discrepant levels of severity across assessment sites / Ira L. COHEN in Research in Autism Spectrum Disorders, 107 (September 2023)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 107 (September 2023) . - p.102206 Titre : PDDBI and ADOS-2 autism severity scores are correlated but yield discrepant levels of severity across assessment sites Type de document : texte imprimé Auteurs : Ira L. COHEN, Auteur ; Claire SCHUTTE, Auteur ; Laura HEWITSON, Auteur Article en page(s) : p.102206 Langues : Anglais (eng) Mots-clés : ADOS-2 Comparison Score  PDDBI Autism Composite  Diagnostic sites  Autism severity  Comorbidity Index. décimale : PER Périodiques Résumé : Background Previous studies have indicated significant associations between the severity of PDDBI composite T-scores and ADOS severity. However, significant correlations do not necessarily indicate similar absolute levels of severity which can vary with informants and with how cases are ascertained across diagnostic sites. Methods The relationships between the Comparison Score (CS) measure of autism severity from the ADOS-2 and Composite T-scores from the PDD Behavior Inventory (PDDBI) were examined across parent and teacher informants from cases seen at a tertiary diagnostic center (n = 157) and, for parent informants, an additional site - a diagnostic/treatment center (n = 104), which provides services that attracted cases with comorbid medical and behavioral concerns. Results Across informants, CS scores were more strongly correlated with the PDDBI composite scores assessing social communication abilities (EXSCA/C) and overall autism severity (AUTISM/C) than with the composite score assessing repetitive and ritualistic behaviors (REPRIT/C) with mean severity levels of REPRIT/C and AUTISM/C slightly, but significantly, higher for teachers. Across centers, correlations between PDDBI composite scores and CS were very similar. However, while average CS scores were more severe at the tertiary center, PDDBI AUTISM/C scores were more severe at the diagnostic/treatment center solely due to higher REPRIT/C severity T-scores, likely related to their greater rates of comorbid issues. Conclusions These results indicate the importance of using a variety of assessment tools when making diagnostic and treatment decisions and assessing outcome with repetitive and ritualistic behaviors particularly sensitive to ascertainment factors.

The Relationship Between Social Affect and Restricted and Repetitive Behaviors Measured on the ADOS-2 and Maternal Stress / Claire SCHUTTE in Journal of Autism and Developmental Disorders, 48-3 (March 2018)

Social affect and restricted and repetitive behaviors were compared with levels of maternal stress, measured by the Parenting Stress Index, in 102 children with ASD ages 2-12 years of age. Results indicated that social affect and restricted and repetitive behaviors were associated with the mother's stress regarding acceptability of the child's condition. Additionally, restricted and repetitive behaviors were significantly related to stress involving the child's hyperactivity and impulsivity. These findings highlight specific areas of stress experienced by mothers of children with ASD that are related to the child's symptoms, providing information for caregiver support and intervention.
