The Moderating Role of Genetics: The Effect of Length of Hospitalization on Children’s Internalizing and Externalizing Behaviors

Abstract: The study considered individual differences in children’s ability to adjust to hospitalization and found the length of hospitalization to be related to adaptive psychological functioning for some children. Applying the theoretical framework of three competing models of gene-X-environment interactions (diathesis–stress, differential susceptibility, and vantage sensitivity), the study examined the moderating effect of genetics (DRD4) on the relationship between the length of hospitalization and internalizing and… Show more

“…This study did not assess the accumulative effect of interventions or time progression of the effect and this topic needs to be addressed in future studies, particularly because in this study the length of stay in hospital was variable and length of stay can affect stress levels. 69,70 These findings support and justify the implementation of humor therapy programs in pediatric units of hospitals. Humor therapy is low cost, does not create adverse effects, and is easy to implement.…”

“…Variaciones en los genes que sintetizan receptores, el transportador y las enzimas de degradación de la dopamina pueden moderar el impacto que tiene la VF sobre el desarrollo neuropsicológico infantil y adulto. Se ha documentado que un polimorfismo de más de siete repeticiones en el gen del receptor 4 de la dopamina (DRD4-7r) confiere mayor sensibilidad durante la niñez a las situaciones adversas, de tal forma que personas con esta variación y expuestas a amenazas pueden mostrar mayor impulsividad, problemas de conducta, ansiedad, déficit atencional y disregulación general del sistema de recompensas (Bakermans-Kranenburg, et al, 2011;Belsky y Pluess, 2013;Benish-Weisman et al, 2015;Das, et al, 2011;Jiang, Chew, y Ebstein, 2013;Ptácek, Kuzelová, y Stefano, 2011).…”

“…Alelo con más de 7 repeticiones (7r) sintetizan un receptor con baja afinidad que se asocia con la disrregulación del sistema de recompensas (Jiang, Chew & Ebstein, 2013). El 7r se ha vinculado con riesgo para desarrollar problemas psicológicos (Benish-Weisman et al 2015). Este polimorfismo se asocia con rasgos de extroversión, impulsividad, búsqueda de la novedad y alto tono hedónico (Knafo, Israel & Ebstein, 2011).…”

“…Existen al menos tres modelos para comprender la interacción GxA. El modelo diátesis-estrés propone que los individuos poseen características biológicas y psicológicas que los hacen más vulnerables a las condiciones de adversidad (Benish-Weisman et al, 2015). El modelo de ventaja a la sensibilidad asume que algunos individuos son altamente sensibles a los ambientes positivos y logran sacar enorme provecho de las situaciones de apoyo y cuidado social, pero serían insensibles a los ambientes adversos.…”
