Changes in self-concept and risk of psychotic experiences in adolescence: a longitudinal population-based cohort study / Colm HEALY in Journal of Child Psychology and Psychiatry, 60-11 (November 2019)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 60-11 (November 2019) . - p.1164-1173 Titre : Changes in self-concept and risk of psychotic experiences in adolescence: a longitudinal population-based cohort study Type de document : texte imprimé Auteurs : Colm HEALY, Auteur ; Helen COUGHLAN, Auteur ; Justin WILLIAMS, Auteur ; Margaret CLARKE, Auteur ; Ian KELLEHER, Auteur ; Mary CANNON, Auteur Article en page(s) : p.1164-1173 Langues : Anglais (eng) Mots-clés : Psychotic experiences  child development  preventative psychiatry  self-concept Index. décimale : PER Périodiques Résumé : BACKGROUND: Psychotic experiences (PEs) are commonly reported in adolescence and are associated with a range of negative outcomes. Few targets for intervention for PEs have been identified. One potential target is self-concept: an individual's beliefs about his/her personal attributes. Improvements in self-concept have been shown to reduce psychotic symptoms in patients with schizophrenia but no study has investigated the relationship between changes in self-concept and risk of PEs in the general population. We aimed to investigate: (a) the relationship between child and adolescent self-concept and adolescent PEs; and (b) whether changes in self-concept between childhood and adolescence were associated with risk of adolescent PEs. METHOD: Using data from age 9 and age 13 (n = 7,423) of the child cohort (Cohort'98) from the Growing Up in Ireland study we investigated the relationship between self-concept at age 9 and age 13 and PEs at age 13. PEs were measured using the Adolescent Psychotic Symptoms Screener and self-concept was measured using the Piers Harris-II. Using a stratified analysis, we investigated the relationship between change in self-concept between age 9 and age 13 and the risk of PEs at age 13. Additionally we investigated changes across the six self-concept subscales. RESULTS: Psychotic experiences were reported by 13% of participants at age 13. 'Very low' self-concept at age 9 was associated with an increased risk of PEs at age 13 (Adjusted-OR: 2.74, CI: 1.80-4.19), and 'High' self-concept at age 9 was associated with a decreased risk of PEs at age 13 (Adjusted-OR: 0.77, CI: 0.60-0.97). The stratified analysis indicated that improvements in self-concept reduced the odds of adolescent PEs and decline in self-concept increased the odds of adolescent PEs. This effect was noted across the majority of the self-concept subscales. CONCLUSIONS: There is a strong relationship between self-concept and PEs. The antecedents of low self-concept may be a useful target for preventative psychiatry. Broad-spectrum interventions targeting self-concept in childhood may help to reduce the incidence of PEs in adolescence.

Changes in the Sulcal Size Associated With Autism Spectrum Disorder Revealed by Sulcal Morphometry / Mahsa SHOKOUHI in Autism Research, 5-4 (August 2012)  

Public ISBD [article]  inAutism Research > 5-4 (August 2012) . - p.245-52 Titre : Changes in the Sulcal Size Associated With Autism Spectrum Disorder Revealed by Sulcal Morphometry Type de document : texte imprimé Auteurs : Mahsa SHOKOUHI, Auteur ; Justin H.G. WILLIAMS, Auteur ; Gordon D. WAITER, Auteur ; Barrie CONDON, Auteur Année de publication : 2012 Article en page(s) : p.245-52 Langues : Anglais (eng) Mots-clés : autism  sulcal morphometry  MRI  Brainvisa Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is a complex, neurodevelopmental disorder with various structural abnormalities for different patient groups. Because of the heterogeneity of the disorder, several biomarkers have been suggested so far. Here, we explore the potential of sulcal surface and length as biomarkers. Three-dimensional T1-weighted images of 15 adolescents of normal intelligence with ASD and 15 age-, sex-, and intelligence quotient-matched control adolescents were analysed using Brainvisa 4.0 (http://www.brainvisa.info), which automatically extracts the cortical folds and labels them as 59 sulcal pieces. For each sulcus, the surface, length, and mean geodesic depth were computed using morphometry analysis within this software package. General linear model was conducted to compare the estimated values for the two groups, ASD and control. In the ASD group, the left insula and the right intraparietal sulcus (IPS) had significantly higher values for surface and length, respectively. Nonetheless for all sulcal pieces, the mean geodesic depth was not significantly different between the two groups. Our results suggest that sulcal surface and length can have correlation with morphological changes of cortex in ASD. Greater surface area and length in insula and IPS, respectively, may reflect greater folding. This could result in greater separation of functions with an impact upon the integrative functions of these regions.

Characteristics of socially successful elementary school-aged children with autism / Jill LOCKE in Journal of Child Psychology and Psychiatry, 58-1 (January 2017)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 58-1 (January 2017) . - p.94-102 Titre : Characteristics of socially successful elementary school-aged children with autism Type de document : texte imprimé Auteurs : Jill LOCKE, Auteur ; Justin H.G.

However, some children with ASD have social outcomes that are consistent with their typically developing counterparts. Little is known about this subgroup of children with ASD. This study examined the stable (unlikely to change) and malleable (changeable) characteristics of socially successful children with ASD. Methods This study used baseline data from three intervention studies performed in public schools in the Southwestern United States. A total of 148 elementary-aged children with ASD in 130 classrooms in 47 public schools participated. Measures of playground peer engagement and social network salience (inclusion in informal peer groups) were obtained. Results The results demonstrated that a number of malleable factors significantly predicted playground peer engagement (class size, autism symptom severity, peer connections) and social network salience (autism symptom severity, peer connections, received friendships). In addition, age was the only stable factor that significantly predicted social network salience. Interestingly, two malleable (i.e., peer connections and received friendships) and no stable factors (i.e., age, IQ, sex) predicted overall social success (e.g., high playground peer engagement and social network salience) in children with ASD. Conclusions School-based interventions should address malleable factors such as the number of peer connections and received friendships that predict the best social outcomes for children with ASD.

Developmental screening and early intervention in a childcare setting for young children at risk for autism and other developmental delays: A feasibility trial / Amanda GULSRUD in Autism Research, 12-9 (September 2019)  

Public ISBD [article]  inAutism Research > 12-9 (September 2019) . - p.1423-1433 Titre : Developmental screening and early intervention in a childcare setting for young children at risk for autism and other developmental delays: A feasibility trial Type de document : texte imprimé Auteurs : Amanda GULSRUD, Auteur ; Themba CARR, Auteur ; Justin WILLIAMS, Auteur ; Jonathan L. PANGANIBAN, Auteur ; Felicia JONES, Auteur ; Jackie KIMBROUGH, Auteur ; Wendy SHIH, Auteur ; Connie KASARI, Auteur Article en page(s) : p.1423-1433 Langues : Anglais (eng) Mots-clés : Jasper  children  early detection  intervention-behavioral  treatment research Index. décimale : PER Périodiques Résumé : Efforts to decrease disparity in diagnosis and treatment for under-resourced children with developmental delays, such as autism spectrum disorder, have led to increased interest in developing programs in community settings. One potential setting that has already demonstrated feasibility in conducting universal screening is the childcare setting. The current study conducted developmental screening in a total of 116 children ages 16-80 months of age in an urban low-income community childcare center. Parents of 20 children who screened positive were enrolled in the intervention phase of the study, where children received a staff-delivered targeted early intervention or a waitlist control condition. Given the small and imbalanced sample sizes, confidence intervals from mixed effect models were used to measure changes across time for each group. Of the children who received treatment, there was an average increase in child initiated joint engagement, symbolic play, and language use. This study provides initial feasibility data for the implementation of a screening and early intervention program to service a predominantly low-resource and ethnically diverse population within the childcare system in a large metropolitan city. Autism Res 2019, 12: 1423-1433. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Identifying and delivering treatment services for young children with developmental delays, such as autism spectrum disorder, may be most successful in community settings, especially for those children from under-resourced areas. This study found preliminary evidence that the childcare setting is a good place to conduct screening and deliver early interventions for children at risk for autism and other developmental delays.
