Psychosocial and cognitive predictors of pre-surgical anxiety and emotional and behavioural changes following surgery in children

Kenedy, Juliet Anne January 2013 (has links)
Surgery is a distressing time for children, adolescents and their families. Post-surgery, a significant number of children develop negative emotional and behavioural difficulties, including separation anxiety, sleep difficulties and aggressive behaviour. These changes, in some, become pervasive and affect the child long-term. There is growing literature identifying psychosocial risk factors associated with negative emotional and behavioural changes after surgery including the age of the child, parental anxiety, pain and pre-surgical anxiety. Pre-surgical anxiety and its predictive factors have also been thoroughly investigated, usually measured within the perioperative period. From a cognitive perspective one would hypothesise that worry would be a pre-cursor to pre-surgical anxiety. To date, there has been no empirical investigation into pre-surgical worries in a clinical sample of children and adolescents. This study therefore investigated pre-surgery related worries in children anticipating orthopaedic and spinal surgery, using the children's surgical worries questionnaire. Information on demographic, social, medica1 and psychological factors was also gathered to investigate potential predictive factors of pre-surgical worry. Sixty-three children and their caregivers completed the questionnaires. Children and adolescents were found to worry most about their illness, its repercussions and medical procedures over hospitalisation worries. Child trait anxiety was the most consistent psychological predictive factor of child surgical worry, along with the child's sociability and pre-morbid emotional symptoms. Medical and demographic factors significantly associated with worry included pre-surgica1 pain and also gender. This study provides a quantitative exploration into worry thoughts children have before surgery. Future research with larger numbers would be useful to investigate the results further

Développement des fonctions exécutives et des théories de l’esprit chez l’enfant ayant une cardiopathie congénitale cyanogène opérée en période néonatale / Executive functions and theory of mind development in children with cyanotic congenital heart disease after neonatal open-heart surgery

Calderon Plata, Johanna 22 November 2013 (has links)
L’objectif général de cette thèse est d’explorer le développement des fonctions exécutives (FE) et des théories de l’esprit (TdE) chez l’enfant ayant une cardiopathie congénitale cyanogène (CCC) et ceci à une période clé dans la construction de ces capacités de « haut niveau » et dans leurs relations fonctionnelles réciproques. L’étude des enfants ayant une CCC et présentant un risque d’hypoxie circonscrit à la période néonatale permet d’explorer la vulnérabilité précoce des capacités neurocognitives à maturation tardive comme les FE et les TdE. En adoptant une approche longitudinale et transversale, nos objectifs visent à (1) déterminer la trajectoire développementale des FE (inhibition, mémoire de travail et flexibilité cognitive) et spécifier la nature et le degré de leurs dysfonctionnements (2) caractériser le développement des capacités méta-représentationnelles et évaluer le rôle prédictif des différentes composantes exécutives dans les TdE de premier et deuxième ordre, (3) explorer la généralisation des dysfonctionnements aux TdE avec un contenu mental affectif, (4) déterminer les facteurs de risque neurologique néonataux associés aux déficits exécutifs et en TdE, (5) évaluer la contribution des dysfonctionnements exécutifs, des variables médicales et démographiques sur la prévalence de prise en charge de ces enfants. Une cohorte de 45 enfants nés avec une CCC opérés à coeur ouvert en période néonatale et un groupe d’enfants sains ont été évalués à un âge moyen de 5 ans (T1) puis ont été à nouveau testés pendant deux années consécutives (T2 et T3). Nos résultats ont mis en évidence un profil de dysfonctionnement hétérogène selon l’âge et le domaine cognitif. Ainsi, naitre avec une CCC altère la progression développementale des FE et des TdE avec toutefois une normalisation pour les composantes ayant une émergence plus précoce. Les liens prédictifs observés entre les niveaux initiaux des FE et le développement ultérieur des TdE reflètent des mécanismes de construction typiques mais néanmoins décalés dans le temps. Enfin, le diagnostic prénatal de la CCC, qui a un rôle neuroprotecteur face au risque de cyanose néonatale, est également associé à un meilleur pronostic des FE et des TdE. Ce travail de thèse offre des résultats pionniers dans la compréhension de l’impact des vulnérabilités neurologiques néonatales sur la dynamique développementale de fonctions neurocognitives complexes. / The general aim of this doctoral dissertation is to explore the development of executive functions (EF) and theory of mind (ToM) in school-aged children with a cyanotic congenital heart disease (CHD) at a key developmental period of progression and functional interactions between these “higher order functions”. The study of children born with a cyanotic CHD and exposed to a hypoxic risk limited to the neonatal period allows to explore the early vulnerability of late developing neurocognitive functions such as EF and ToM. We used a longitudinal and cross-sectional approach in order to: (1) determine the developmental trajectory of EF (inhibition, working memory and cognitive flexibility) and specify their nature and degree of impairment, (2) characterize the development of meta-representational abilities as well as EFs predictive roles in first- and second-order ToM, (3) evaluate the potential generalization of dysfunction to ToM with an affective component, (4) determine neonatal neurological risk factors associated to EF and ToM impairments, (5) evaluate the impact of executive impairments and medical and demographic variables on the early use of remediation services in these children. A cohort of 45 children born with a cyanotic CHD who underwent neonatal open-heart surgery and a group of comparison children were evaluated at a mean age of 5 years (T1) and then followed-up for two consecutive years (T2 and T3). Our results showed a heterogeneous pattern of dysfunction depending on age and specific domains. Cyanotic CHD affects the dynamics of development for these functions even though the earliest developing abilities tend to normalize. Predictive relations observed between early EF and later ToM suggest typical developmental mechanisms though chronologically delayed. Finally, prenatal diagnosis of the cyanotic CHD, known to play a neuroprotective role for cyanosis management is also associated to a better prognosis for EF and ToM outcomes. This work offers pioneer results on the comprehension of the impact of neonatal neurological vulnerabilities on the developmental dynamics of complex neurocognitive abilities.
