ABSTRACT
Objective:To explore the related factors to the effect of cognitive behavior therapy (CBT) for adults with attention-deficit/hyperactivity disorder(ADHD).Methods:A prospective and open-label,self-control study was designed.Eighty-five adult patients from outpatient department with ADHD diagnosed with the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-Ⅳ).All the patients received 12 weeks of CBT,the ADHD Rating Scale (ADHD-RS) was used to evaluate ADHD core symptoms,and according to the post-treat ADHD-RS reduction ratio,41 patients were divided into responders(ADHD-RS reduction ratio≥25％)and 44 patients were divided into non-responders(ADHD-RS reduction ratio ＜ 25％).The t-test and chi-square test were used to analyze the differences of sociodemographic variables,clinical variables and early efficacy (ADHD-RS reduction ratio≥25％ in the fourth week) between the two groups,and logistics regression was used to analysis the related factors.Results:Comparing with the group of non-responders,there was more cases with early efficacy (P ＜ 0.05)in the group of responders.Logistic models indicated that higher scores of BIS-motor (OR =1.27),early efficacy (OR =11.87) were associated with better CBT efficacy.Conclusion:It suggests that ADHD adults with more sever motor impulsiveness symptom,and early efficacy may get favorable response to CBT.
ABSTRACT
En el presente artículo se lleva a cabo una reflexión y análisis de la adaptación para Colombia de la Escala Barratt de Impulsividad para niños (Bis-11c). A la luz de los fundamentos teóricos en los que se basó el desarrollo del instrumento, en este proceso se revisa la estructura factorial y la confiabilidad encontrada. También se compara con las diversas versiones que la escala ha tenido hasta la fecha, tanto en muestras pertenecientes a población infantil como adulta. A partir de todo ello, se proponen pautas para mejorar las propiedades psicométricas de la escala.
This paper is based on the analysis of impulsivity of Colombian children using the Barrat scale (Bis-11c). In this process the factor structure and reliability are reviewed based on theoretical foundation. Additionally, a comparative study considered different versions of the scale thus far using sample tests with both children and adults. Some ideas to improve (Bis-11c) psychometric properties are given.
ABSTRACT
Introducción: La Escala de Impulsividad de Barratt (BIS) es uno de los instrumentos más frecuentemente usados para evaluar la impulsividad. Este artículo describe la confiabilidad y validez de la BIS-11 en adolescentes chilenos. Sujetos y Métodos: El estudio se efectuó en estudiantes de enseñanza media (n = 763). La confiabilidad se evaluó con análisis de consistencia interna y homogeneidad de los ítems. Para la validez se empleó coeficiente de correlación de Pearson y prueba t de student para muestras independientes. Resultados: La escala obtuvo un coeficiente alfa de Cronbach de 0,77 y su puntaje total correlacionó significativamente con impulsividad según DSM IV, impulsividad según reporte del profesor, intento de suicidio y consumo de alcohol. Conclusiones: La BIS-11 es una medida de impulsividad con adecuada confiabilidad y validez en esta población.
Background: The Barratt Impulsivity Scale (BIS) is one of the most commonly used scales for the assessment of impulsiveness. This report describes the reliability and validity of the BIS-11. Subjects and Methods: The study was conducted in high school students (n = 763). The reliability was evaluated with analysis of internal consistency and homogeneity of the items. For the validity Pearson coefficient of correlation and the student t-test for independent sample were used. Results: The scale obtained a Cronbach alpha coefficient of 0,77, and the total scores of the scale correlated significantly with impulsivity according to DSMIV, impulsivity according to the teacher, suicide attempt and alcohol consumption. Conclusions: The BIS-11 is a valid and reliable measure of impulsivity in this population.
