Methods: In a two-phase design a community sample of 4,662 6-year-old twin-pairs were sampled and 854 pairs were assessed in the second phase for normative repetitive routines using the Childhood Routines Inventory (CRI) and for OCSS by maternal-informant diagnostic interview. The OCSS phenotype was defined using standard diagnostic criteria for obsessive compulsive disorder, though regardless of impairment. Results: In the bivariate model, correlation between the CRI defined phenotype and the OCSS phenotype was estimated to be .40 (95% CI .27–.50), and this correlation was attributable wholly to additive genetic effects. The bivariate model also provided estimates of heritability of the two phenotypes separately: 55% (95% CI 80–89%) for the OCSS phenotype, with the remaining variance attributable mainly to non-shared environment, and 50% (95% CI 39–62%) for CRI assessed normative repetitive routines of childhood, with 36% of the remaining variance attributable to shared environment and 14% to non-shared. Conclusions: The moderate correlation between normative childhood repetitive routines and obsessive compulsive symptomatology, attributable to genetic factors, is consistent with the hypothesis that high levels of this trait in young children constitute a risk factor for the development of obsessive compulsive symptoms.

Randomized controlled trial of full and brief cognitive-behaviour therapy and wait-list for paediatric obsessive-compulsive disorder / Derek BOLTON in Journal of Child Psychology and Psychiatry, 52-12 (December 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-12 (December 2011) . - p.1269-1278 Titre : Randomized controlled trial of full and brief cognitive-behaviour therapy and wait-list for paediatric obsessive-compulsive disorder Type de document : Texte imprimé et/ou numérique Auteurs : Derek BOLTON, Auteur ; Tim WILLIAMS, Auteur ; Sean PERRIN, Auteur ; Linda ATKINSON, Auteur ; Catherine GALLOP, Auteur ; Polly WAITE, Auteur ; Paul SALKOVSKIS, Auteur Année de publication : 2011 Article en page(s) : p.1269-1278 Langues : Anglais (eng) Mots-clés : CBT  obsessive-compulsive disorder  children  adolescents Index. décimale : PER Périodiques Résumé : Background:  Reviews and practice guidelines for paediatric obsessive-compulsive disorder (OCD) recommend cognitive-behaviour therapy (CBT) as the psychological treatment of choice, but note that it has not been sufficiently evaluated for children and adolescents and that more randomized controlled trials are needed. The aim of this trial was to evaluate effectiveness and optimal delivery of CBT, emphasizing cognitive interventions. Methods:  A total of 96 children and adolescents with OCD were randomly allocated to the three conditions each of approximately 12 weeks duration: full CBT (average therapist contact: 12 sessions) and brief CBT (average contact: 5 sessions, with use of therapist-guided workbooks), and wait-list/delayed treatment. The primary outcome measure was the child version of the semi-structured interviewer-based Yale-Brown Obsessive Compulsive Scale. Clinical Trial registration: http://www.controlled-trials.com/ISRCTN/; unique identifier: ISRCTN29092580. Results:  There was statistically significant symptomatic improvement in both treatment groups compared with the wait-list group, with no significant differences in outcomes between the two treatment groups. Controlled treatment effect sizes in intention-to-treat analyses were 2.2 for full CBT and 1.6 for brief CBT. Improvements were maintained at follow-up an average of 14 weeks later. Conclusions:  The findings demonstrate the benefits of CBT emphasizing cognitive interventions for children and adolescents with OCD and suggest that relatively lower therapist intensity delivery with use of therapist-guided workbooks is an efficient mode of delivery.

Risk Factors for Long-term Psychological Effects of a Disaster Experienced in Adolescence: Predictors of Post Traumatic Stress Disorder / Orlee UDWIN in Journal of Child Psychology and Psychiatry, 41-8 (November 2000)

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 41-8 (November 2000) . - p.969-979 Titre : Risk Factors for Long-term Psychological Effects of a Disaster Experienced in Adolescence: Predictors of Post Traumatic Stress Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Orlee UDWIN, Auteur ; Stephanie BOYLE, Auteur ; William YULE, Auteur ; Derek BOLTON, Auteur ; Dominic O'RYAN, Auteur Année de publication : 2000 Article en page(s) : p.969-979 Langues : Anglais (eng) Mots-clés : Adulthood  disaster  longitudinal studies  PTSD  prediction  risk factors Index. décimale : PER Périodiques Résumé : This paper examines risk factors for the development of Post Traumatic Stress Disorder (PTSD), and its severity and chronicity, in a group of 217 young adults who survived a shipping disaster in adolescence. The survivors were followed up 5 to 8 years after the disaster. Risk factors examined fell into three main categories: pre-disaster child and family vulnerability factors, including childhood psychopathology; objective and subjective disaster-related experiences; and post-disaster factors, including results from screening questionnaires administered 5 months post-disaster, coping mechanisms adopted subsequently, life events, and availability of social supports. Developing PTSD following the disaster was significantly associated with being female, with pre-disaster factors of learning and psychological difficulties in the child and violence in the home, with severity of exposure to the disaster, survivors' subjective appraisal of the experience, adjustment in the early post-disaster period, and life events and social supports subsequently. When all these factors were considered together, measures of the degree of exposure to the disaster and of subjective appraisal of life threat, and ratings of anxiety obtained 5 months post-disaster, best predicted whether survivors developed PTSD. For those survivors who developed PTSD, its duration and severity were best predicted not by objective and subjective disaster-related factors, but by pre-disaster vulnerability factors of social, physical, and psychological difficulties in childhood together with ratings of depression obtained 5 months post-disaster, and whether survivors received post-disaster support at school. The implications of these findings are considered for targeting assessment and intervention efforts at survivors most at risk of developing difficulties in adjustment following similar traumatic experiences.
