The Wechsler Intelligence Scale for Children and the Stanford–Binet are commonly used in autism spectrum disorder evaluations and scores from these tests have been shown to be highly correlated in typically developing populations. However, they have not been compared in individuals with autism spectrum disorder, whose core symptoms can make testing challenging, potentially compromising test reliability. We used a within-subjects research design to evaluate the convergent validity between the Wechsler Intelligence Scale for Children, 4th ed., and Stanford–Binet, 5th ed., in 40 youth (ages 10–16?years) with autism spectrum disorder. Corresponding intelligence scores were highly correlated (r?=?0.78 to 0.88), but full-scale intelligence quotient (IQ) scores (t(38)?=??2.27, p?=?0.03, d?=??0.16) and verbal IQ scores (t(36)?=?2.23, p?=?0.03; d?=?0.19) differed between the two tests. Most participants obtained higher full-scale IQ scores on the Stanford–Binet, 5th ed., compared to Wechsler Intelligence Scale for Children, 4th ed., with 14% scoring more than one standard deviation higher. In contrast, verbal indices were higher on the Wechsler Intelligence Scale for Children, 4th ed., Verbal–nonverbal discrepancy classifications were only consistent for 60% of the sample. Comparisons of IQ test scores in autism spectrum disorder and other special groups are important, as it cannot necessarily be assumed that convergent validity findings in typically developing children and adolescents hold true across all pediatric populations.

Sleep restriction worsens mood and emotion regulation in adolescents / Katherine T. BAUM in Journal of Child Psychology and Psychiatry, 55-2 (February 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-2 (February 2014) . - p.180-190 Titre : Sleep restriction worsens mood and emotion regulation in adolescents Type de document : Texte imprimé et/ou numérique Auteurs : Katherine T. BAUM, Auteur ; Anjali DESAI, Auteur ; Julie FIELD, Auteur ; Lauren E. MILLER, Auteur ; Joseph RAUSCH, Auteur ; Dean W. BEEBE, Auteur Article en page(s) : p.180-190 Langues : Anglais (eng) Mots-clés : Adolescence  sleep  anxiety  mental health  pediatrics Index. décimale : PER Périodiques Résumé : Background The relationship between inadequate sleep and mood has been well-established in adults and is supported primarily by correlational data in younger populations. Given that adolescents often experience shortened sleep on school nights, we sought to better understand the effect of experimentally induced chronic sleep restriction on adolescents’ mood and mood regulation. Methods Fifty healthy adolescents, ages 14–17, completed a 3-week sleep manipulation protocol involving a baseline week, followed by a sleep restriction (SR) condition (6.5 hr in bed per night for five nights) and healthy sleep duration (HS) condition (10 hr in bed per night for five nights). The study used a randomized, counterbalanced, crossover experimental design. Participants’ sleep was monitored at home via self-report and actigraphy. At the end of each condition, participants and their parents completed questionnaires of mood and mood regulation. To assess for expectancy effects, we also analyzed parent and teen ratings of hyperactivity/impulsivity, which prior research suggests is not sensitive to SR in adolescents. Wilcoxon Signed Rank tests compared questionnaire outcomes across the two conditions. Results Participants averaged 2.5 more hours of sleep per night during HS relative to SR. Compared with HS, adolescents rated themselves as significantly more tense/anxious, angry/hostile, confused, and fatigued, and as less vigorous (p = .001–.01) during SR. Parents and adolescents also reported greater oppositionality/irritability and poorer emotional regulation during SR compared with HS (p .05). There were no cross-condition differences in depression or hyperactivity/impulsivity (p .05). Conclusions Findings complement prior correlational study results to show that after only a few days of shortened sleep, at a level of severity that is experienced regularly by millions of adolescents on school nights, adolescents have worsened mood and decreased ability to regulate negative emotions.
