Factores predictores del tratamiento de la bulimia nerviosa con Terapia Interpersonal

Objetivo: Determinar los factores de pronostico del tratamiento de la bulimia nerviosa con terapia interpersonal. Diseno: 80 pacientes con el diagnostico de Bulimia Nerviosa (BN) o trastornos del comportamiento alimentario no especificados con caracteristicas de BN (TCANE) fueron tratados con 16 sesiones de terapia interpersonal. Los pacientes fueron evaluados utilizando una entrevista semi-estructural (Clinical Eating Disorders Rating Instrument-CEDRIC). Tambien completaron una bateria de cuestionarios para evaluar los niveles de estima personal (Rosenberg Self-esteem Scale -RSE), la psicopatologia de los trastornos de la alimentacion (Eating Disorders Examination Questionnaire-EDE-Q), la funcion interpersonal (Inventory of Interpersonal Functioning-IIP-32) y los niveles de depresion (Beck Depression Inventory-BDI). Metodo: El pronostico de interes fue definido por la variable de remision y recuperacion. Para el analisis del estudio se realizaron una serie de regresiones logisticas. Resultado: Baja estima personal, y una menor patologia en la funcion interpersonal fueron los factores de peor pronostico. Conclusion: Aunque la terapia interpersonal es un tratamiento efectivo para las personas que sufren de bulimia nerviosa, los pacientes con estas patologias con baja estima personal y menos problemas interpersonales deberian de ser tratados con otro tipo de terapia. Objective: To determine predictors of treatment outcomes in patients with Bulimic Eating Disorders treated with Interpersonal Psychotherapy (IPT). Design: Following initial assessment, 80 patients with diagnoses of Bulimia Nervosa or Eating Disorders Not Otherwise Specified (EDNOS), entered treatment in the form of 16 sessions of IPT. Patients were assessed using a validated semi-structure interview (Clinical Eating Disorders Rating Instrument-CEDRIC) and completed measures of self-esteem (Rosenberg Self-esteem Scale-RSE), eating psychopathology (Eating Disorders Examination Questionnaire-EDE-Q), interpersonal functioning (Inventory of Interpersonal Functioning- IIP-32), and depression (Beck Depression Inventory-BDI). Method: Remission and recovery after 16 sessions of IPT were the two outcomes of interest. Univariate analysis and a series of backwards stepping logistic regressions were performed to determine the variables associated with remission and recovery. Result: Low self-esteem and less interpersonal problems were the main predictors of poor outcome. Conclusion: As patients with Bulimic Disorders with low levels of interpersonal problems and high levels of low self-esteem are likely to do less well with IPT, different type of treatment should be offered to them. A randomized controlled trial could explore this hypothesis in more detail.
