The DSM-IV criteria recognize the existence of obsessive-compulsive disorder (OCD) with poor insight. However, there is paucity of literature on the clinical correlates and treatment response in poor and good insight OCD. In this study, insight is measured by using the Brown Assessment of Beliefs Scale (BABS) developed specifically to assess insight. One hundred subjects with DSM-IV OCD were ascertained from the OCD clinic of a large psychiatric hospital in India. All subjects were evaluated extensively by using structured instruments and established measures of psychopathology. The subjects were treated with adequate doses of drugs for adequate period. The results showed that 25% of the subjects had poor insight. Poor insight was associated with earlier age-at-onset, longer duration of illness, more number of obsessive-compulsive symptoms, more severe illness and higher comorbidity rate, particularly major depression. Of the subjects who were treated adequately (N = 73), 44 (60%) were treatment responders. Poor insight was associated with poor response to drug treatment. In the step-wise logistic regression analysis, baseline BABS score was highly predictive of poor treatment response. Poor insight appears to be associated with specific clinical correlates and poor response to drug treatment. Further studies are needed in larger samples to replicate our findings.
ResumenLos criterios del DSM-IV reconocen la existencia del trastorno obsesivo-compulsivo (TOC) con poca conciencia de enfermedad. Sin embargo, hay una escasez de publicaciones sobre los correlatos clínicos y la respuesta al tratamiento en TOC con poca conciencia de enfermedad y con buena conciencia de enfermedad. En este estudio, la conciencia de enfermedad se mide utilizando la Escala de Evaluación de las Creencias de Brown (BABS) desarrollada específicamente para evaluar la conciencia de enfermedad. Se comprobó a cien sujetos con TOC del DSM-IV de la clínica de TOC de un gran hospital psiquiátrico en India. Todos los sujetos recibieron una evaluación arnplia utilizando instrumentos estructurados y medidas establecidas de trastornos psicopatológicos. Se trató a los sujetos con dosis adecuadas de fármacos durante un periodo adecuado. Los resultados mostraron que el 25% de los sujetos tenían poca conciencia de enfermedad. La poca conciencia de enfermedad se asociaba con edad anterior en el comienzo, duración más larga de la enfermedad, mayor número de síntomas obsesivo-compulsivos, enfermedad más grave y tasa más alta de comorbilidad, particularmente de depresión mayor. De los sujetos que recibieron tratamiento adecuado (n = 73), 44 (el 60%) respondieron al tratamiento. La poca conciencia de enfermedad se asociaba con mala respuesta al tratamiento farmacológico. En el análisis de regresión logística paso a paso, la puntuación de la BABS en la línea de base predecía muy bien la mala respuesta al tratamiento. La poca conciencia de enfermedad parece asociarse con correlatos clínicos específicos y mala respuesta al tratamiento farmacológico. Se necesitan más estudios en muestras mayores para replicar nuestros hallazgos.
