ABSTRACT
Objectives: This study investigated behavioral self-regulation problems using the Children's Hostility Inventory (CHI) in pediatric bipolar disorder (PBD), healthy offspring of bipolar disorder patients (HOBD), and healthy controls (HC) without previous history of psychiatric disorders. Methods: The CHI was administered to 41 consecutive children and adolescents diagnosed with PBD, to 16 HOBD, and to 22 HC. The inventory assessed irritability, expression, hostility, and aggression and was completed by the children with the help of their mothers. Adolescents and their respective parents were interviewed separately using the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL). Results: All subscales of the CHI presented statistically significant differences, except for the subscale assessing feelings of suspicion. Pairwise comparisons revealed consistently significant differences between the PBD group and controls, indicating more self-regulation difficulties in the PBD group, represented by high levels of hostility and aggressive behavior. There were no significant differences between the PBD and HOBD groups. Conclusions: Future studies should further investigate if such behavior is state-dependent or a trait of bipolar juvenile expression. Expression of hostility and irritability should be considered relevant targets in psychosocial approaches addressing this population.
ABSTRACT
Abstract Introduction: Literature reports show that bipolar offspring (BO) present with a wide range of psychiatric disorders. Comparison between BO and control parent offspring (CPO) may help to identify which psychopathological findings are specific to this high-risk group. Objective: To compare the psychopathological characteristics between a group of BO type-I and a group of CPO, by identifying the presence of psychiatric disorders according the DSM-IV-TR. Methods: A descriptive-correlational, cross-sectional and comparative study was conducted with 127 offspring of parents with bipolar disorder type-I from the multimodal intervention programme (PRISMA) and with 150 CPO between 6 and 30 years of age. Subjects were evaluated with validated diagnostic interviews (K-SADS-PL and DIGS). Results: The BO group showed higher frequencies for bipolar disorder (prevalence ratio [PR] = 17.70; 95% confidence interval [CI]; 1.02-306.83), bipolar disorder not otherwise specified (PR = 23.07, 95% CI; 2.8-189.0, p = 0.0001), disorders due to psychoactive substance use (PR = 9.52,95% CI; 2.93-30.90), oppositional defiant disorder (PR = 4.10,95% CI; 1.70-9.89), posttraumatic stress disorder (PR = 3.90, 95% CI 1.30-11.66), disorder due to alcohol use (PR = 3.84, 95% CI; 1.28-11.48), attention deficit/hyperactivity disorder (PR = 2.26, 95% CI; 1.37-3.75), and major depressive disorder (PR = 2.25, 95% CI; 1.13-4.50). Statistically significant differences were also found in the CGAS and GAF functional scales, with lower scores for the BO group. Conclusion: These findings confirm previous literature reports showing that BO have higher rates of affective and non-affective psychiatric disorders than control subjects, and also a lower level of global functioning.
Resumen Introducción: Reportes en la literatura muestran que los Hijos de Padres con Trastorno Bipolar tipo I (HPTB) manifiestan un amplio rango de trastornos psiquiátricos. La comparación entre los HPTB y los Hijos de Padres Control (HPC) permite establecer cuáles hallazgos psicopatológicos son específicos de este grupo de alto riesgo. Objetivo: Comparar las características psicopatológicas entre un grupo de HPTB tipo I y un grupo de HPC, mediante la identificación de la presencia de trastornos psiquiátricos según el DSM-IV-TR. Metodología: Se realizó un estudio descriptivo-correlacional, comparativo de corte transversal con 127 Hijos de Padres con TAB tipo I (HPTB-I) dentro de un programa de intervención multimodal (PRISMA) y 150 HPC, con edades entre los seis y 30 años. Los sujetos fueron evaluados con entrevistas diagnósticas validados (K-SADS-PL y DIGS). Resultados: El grupo de HPTB mostró mayor frecuencias de trastorno bipolar (Razón de Prevalencia [RP] = 17,70; Intervalo de Confianza [IC] del 95%, 1,02-306,83), trastorno bipolar no especificado (RP = 23,07, IC 95% 2,8 -189, p = 0.0001), trastorno por uso de sustancias psi-coactivas (RP = 9,52; IC 95%, 2,93-30,90), trastorno oposicionista desafiante (RP = 4,10; IC 95%, 1,70-9,89); trastorno de estrés postraumático (RP = 3,90; IC 95%, 1,30-11,66), trastorno por uso de alcohol (RP = 3,84; IC 95%, 1,2811,48), trastorno por déficit de atención e hiperactividad (RP = 2,26; IC 95%, 1,37-3,75) y trastorno depresivo mayor (RP = 2,25; IC 95%, 1,13-4,50). También se encontraron diferencias estadísticamente significativas en las escalas de funcionalidad CGAS y GAF, con menor puntaje en el grupo de HPB. Conclusión: Estos hallazgos confirman reportes previos de la literatura que demuestran que los HPTB presentan mayores tasas de trastornos psiquiátricos afectivos y no afectivos, y una menor nivel de funcionalidad global, al ser comparados con sujetos controles de la comunidad.
