Aetiological overlap between anxiety and attention deficit hyperactivity symptom dimensions in adolescence / Giorgia MICHELINI in Journal of Child Psychology and Psychiatry, 56-4 (April 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-4 (April 2015) . - p.423-431 Titre : Aetiological overlap between anxiety and attention deficit hyperactivity symptom dimensions in adolescence Type de document : Texte imprimé et/ou numérique Auteurs : Giorgia MICHELINI, Auteur ; Thalia C.

MCADAMS, Auteur Article en page(s) : p.423-431 Langues : Anglais (eng) Mots-clés : Anxiety  ADH problems  genetics  twins  adolescence Index. décimale : PER Périodiques Résumé : Background Anxiety and attention-deficit/hyperactivity (ADH) problems are common in adolescence, often co-occur, and are characterised by high heterogeneity in their phenotypic expressions. Although it is known that anxiety and ADH problems correlate, the relationships between subtypes of anxiety and ADH problems have been scarcely investigated. Methods Using a large population sample of adolescent twins and siblings we explored the phenotypic and aetiological association between anxiety subtypes (panic/agoraphobia, separation anxiety, social anxiety, physical injury fears, obsessive-compulsive symptoms and generalised anxiety) and the two ADH dimensions (attention problems and hyperactivity/impulsivity). Both phenotypes were assessed using self-report questionnaires. Results The association between ADH problems and anxiety could be entirely attributed to attention problems, not hyperactivity/impulsivity. Most of the correlations between anxiety subtypes and attention problems showed an approximately equal role of genetic and nonshared environmental factors. Conclusions The high heterogeneity within anxiety and ADH problems should be taken into account in order to better understand comorbidity between them.

Annual Research Review: Sleep problems in childhood psychiatric disorders – a review of the latest science / Alice M. GREGORY in Journal of Child Psychology and Psychiatry, 57-3 (March 2016)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 57-3 (March 2016) . - p.296-317 Titre : Annual Research Review: Sleep problems in childhood psychiatric disorders – a review of the latest science Type de document : Texte imprimé et/ou numérique Auteurs : Alice M. GREGORY, Auteur ; Avi SADEH, Auteur Article en page(s) : p.296-317 Langues : Anglais (eng) Mots-clés : Sleep  psychopathology  child  adolescent  review Index. décimale : PER Périodiques Résumé : Background Hippocrates flagged the value of sleep for good health. Nonetheless, historically, researchers with an interest in developmental psychopathology have largely ignored a possible role for atypical sleep. Recently, however, there has been a surge of interest in this area, perhaps reflecting increased evidence that disturbed or insufficient sleep can result in poor functioning in numerous domains. This review outlines what is known about sleep in the psychiatric diagnoses most relevant to children and for which associations with sleep are beginning to be understood. While based on a comprehensive survey of the literature, the focus of the current review is on the latest science (largely from 2010). There is a description of both concurrent and longitudinal links as well as possible mechanisms underlying associations. Preliminary treatment research is also considered which suggests that treating sleep difficulties may result in improvements in behavioural areas beyond sleep quality. Findings To maximise progress in this field, there now needs to be: (a) greater attention to the assessment of sleep in children; (b) sleep research on a wider range of psychiatric disorders; (c) a greater focus on and examination of mechanisms underlying associations; (d) a clearer consideration ofdevelopmental questions and (e) large-scale well-designed treatment studies. Conclusions While sleep problems may sometimes be missed by parents and healthcare providers; hence constituting a hidden risk for other psychopathologies – knowing about these difficulties creates unique opportunities. The current excitement in this field from experts in diverse areas including developmental psychology, clinical psychology, genetics and neuropsychology should make these opportunities a reality.

Assessing gene–environment interactions on anxiety symptom subtypes across childhood and adolescence / Jennifer Y.F. LAU in Development and Psychopathology, 19-4 (Fall 2007)  

Public ISBD [article]  inDevelopment and Psychopathology > 19-4 (Fall 2007) . - p.1129-1146 Titre : Assessing gene–environment interactions on anxiety symptom subtypes across childhood and adolescence Type de document : Texte imprimé et/ou numérique Auteurs : Jennifer Y.F. LAU, Auteur ; Daniel Samuel PINE, Auteur ; Thalia C. ELEY, Auteur ; Alice M. GREGORY, Auteur ; Michelle A. GOLDWIN, Auteur Année de publication : 2007 Article en page(s) : p.1129-1146 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Consistent evidence shows both genetic and stress-related risks on child and adolescent anxiety, yet few studies have considered the degree to which genetic effects are moderated by stress (gene–environment interaction). We used longitudinal data from both a child and adolescent sample of twins to examine three novel issues on the presence of gene–environment interaction on anxiety symptoms. First, we assessed moderation of genetic risks on anxiety symptoms by negative life events in each age group. Second, by distinguishing between “stable” and “age-specific” genetic factors, we explored the continuity of gene–environment interaction across time and/or its emergence at specific ages. Third, we compared the presence of gene–environment interaction across different symptom types (general, panic, social, and separation). Genetic effects on separation anxiety symptoms in childhood (mean age = 8 years, 6 months) and panic anxiety symptoms in adolescence (mean age = 15 years) increased across independent negative life events. Shared environmental effects on separation anxiety symptoms and nonshared environmental effects on general anxiety symptoms in adolescence were also moderated by negative life events. We interpret these preliminary findings tentatively in the context of gene–environment interaction on anxiety in general, and on early separation and later panic anxiety in particular.

Does childhood anxiety evoke maternal control? A genetically informed study / Thalia C. ELEY in Journal of Child Psychology and Psychiatry, 51-7 (July 2010)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 51-7 (July 2010) Titre : Does childhood anxiety evoke maternal control? A genetically informed study Type de document : Texte imprimé et/ou numérique Auteurs : Thalia C. ELEY, Auteur ; Jennifer Y.F. LAU, Auteur ; Alice M. GREGORY, Auteur ; Maria NAPOLITANO, Auteur Année de publication : 2010 Langues : Anglais (eng) Mots-clés : Anxiety maternal-control parenting twins gene–environment-correlation Index. décimale : PER Périodiques Résumé : Background: Despite theoretical and empirical support for an association between maternal control and child anxiety, few studies have examined the origins of this association. Furthermore, none use observer-ratings of maternal control within a genetically informative design. This study addressed three questions: 1) do children who experience maternal control report higher anxiety levels than those who do not?; 2) to what extent do genetic and environmental factors influence maternal control and child anxiety?; 3) to what extent do genetic and environmental factors influence the associations between child anxiety and maternal control? Method: Five hundred and thirty 8-year-old children (from 265 twin pairs) and their mothers were observed participating in an 'etch-a-sketch' task from which maternal control was rated. Children rated their anxiety using the Screen for Child Anxiety Related Emotional Disorders. Results: Children who experienced maternal behaviour rated as 'extreme control' reported higher anxiety levels than those who did not. Maternal control was highly heritable (A = .63), high self-rated anxiety less so (h2g = .36). The overlap between high child anxiety and maternal control was primarily due to shared genetic factors. Conclusions: These results suggest that maternal control is likely to have been elicited by children with high levels of anxiety.
