In Study 1, factor analysis of restricted and repetitive behaviors was carried out using the Repetitive Behavior Questionnaire-2 (RBQ-2), completed by 120 parents of 2- to 17-year-olds with ASD. Two subtypes resulted: repetitive sensory and motor behaviors, and insistence on sameness, accounting for 40% of the variance. This two-factor solution was retained even when the sensory items of the RBQ-2 were removed. In Study 2, 49 of the same parents also completed the Spence Anxiety Scales and the Sensory Profile. The insistence on sameness factor was significantly associated with anxiety while the repetitive motor behaviors factor was not. The relation between anxiety and insistence on sameness was mediated by sensory avoiding and to a lesser extent by sensory sensitivity. Implications for arousal explanations of ASD and for clinical practice are discussed.

Reliability of self, parental, and researcher measurements of head circumference / Jillian SULLIVAN in Molecular Autism, (January 2014)  

Public ISBD [article]  inMolecular Autism > (January 2014) Titre : Reliability of self, parental, and researcher measurements of head circumference Type de document : Texte imprimé et/ou numérique Auteurs : Jillian SULLIVAN, Auteur ; Teresa TAVASSOLI, Auteur ; Kimberly ARMSTRONG, Auteur ; Simon BARON-COHEN, Auteur ; Ayla HUMPHREY, Auteur Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The measurement of head circumference (HC) is widely used in clinical and research settings as a proxy of neural growth. Although it could aid data collection, no studies have explored either the reliability of adult self-measurements or parental measurements of young children. This study therefore aimed to examine whether adult self and parental measurement of HC constitute reliable data.FINDINGS:A total of 57 adults (32 male) were asked to measure their HC twice following written instructions (adult self-measurement). These measures were compared to those of a researcher independently measuring the same participant's HC twice. Additionally, mothers of 25 children (17 male) were also asked to measure their child's HC (parental measure), and again this was compared to researcher measurements of the child's HC. The intraclass correlation coefficient between adult self- and researcher measurement was 0.84 and between parent and researcher measurement was 0.99. The technical error of measurement was also acceptable, within the range of a skilled anthropometrist. The high degree of agreement between researcher and adult self-measurement/parental measurement of HC demonstrates that these different assessors produce similarly reliable and reproducible data. This suggests adult self- and parental measurements can reliably be used for data collection to enable valid large-scale developmental and clinical studies of HC.
