ABSTRACT
Background: Childhood sexual abuse (CSA) is a significant trauma that may have lifelong impact. Due to the long-term negative personal and societal consequences of CSA, it is crucial to find treatments with enduring outcomes. Objective: The aim of this study was to determine the relative long-term efficacy of psychodynamic and systemic group therapy for adult women exposed to CSA. Method: A prospective randomized controlled trial was conducted with outcomes assessed at pre- and post-treatment, and 1 and 5 years post-treatment. All analyses were intention-to-treat. One hundred and six women with sequelae from childhood sexual abuse were treated with psychodynamic or systemic group therapy. Primary outcome was Global Severity Index (GSI) of SCL-90-R. Secondary outcomes included symptoms of PTSD and depression and psycho-social functioning. Results: Treatment was completed by 81% of participants; 64% completed the 1-year follow-up and 60% completed the 5-year follow-up. Completion rates did not differ between treatments. Significant reduction in symptoms measured on GSI and improvement of psychosocial functioning was found for both interventions at all measurement points after treatment (ES range = 0.68-1.19). However, different trajectories were observed: while outcome at end of treatment was significantly better in the systemic group, no differences in gains were observed at the 1- and 5-year follow-ups when controlling for baseline differences. Conclusions: The findings add to the evidence base for psychodynamic and systemic group therapy, but the result also underscores the importance of taking post-treatment trajectories into account in evidence-based research, in the continued efforts to improve treatment for this population.
Antecedentes: El abuso sexual en la infancia (ASI) es un trauma significativo que puede tener un impacto para toda la vida. Dadas las consecuencias negativas personales y sociales del ASI, es crucial encontrar tratamientos con resultados sostenidamente positivos.Objetivo: El objetivo de este estudio fue determinar la eficacia relativa a largo plazo de la terapia grupal psicodinámica y sistémica para mujeres adultas expuestas a ASI.Método: Se realizó un ensayo controlado aleatorizado prospectivo, con evaluaciones pre y post tratamiento, y luego de 1 y 5 años post-tratamiento. Todos los análisis fueron por intención de tratar. Ciento seis mujeres con secuelas derivadas de abuso sexual en la infancia fueron tratadas con terapia grupal psicodinámica o sistémica. El resultado principal fue el índice global de severidad (IGS) del SCL-90-R. Los resultados secundarios incluyeron síntomas de TEPT y depresión, y funcionamiento psicosocial.Resultados: El tratamiento fue completado por 81% de los participantes; 64% de ellos completó el seguimiento luego de un año, y 60% completó el seguimiento luego de cinco años. Se encontró una reducción significativa de síntomas medidos a través del IGS, además de un mejoramiento del funcionamiento psicosocial, en ambas intervenciones y en todo momento de evaluación post-tratamiento (ES rango = 0.68-1.19). No obstante, se observaron diferentes trayectorias: aunque el resultado al final del tratamiento era significativamente mejor en el grupo sistémico, no se observaron diferencias de ganancias en los seguimientos de 1 y 5 años, controlando las diferencias base.Conclusiones: Los hallazgos contribuyen a la evidencia basal para terapia grupal psicodinámica y sistémica, pero los resultados también resaltan la relevancia de considerar las trayectorias post-tratamiento en la investigación basada en evidencia, como parte de los esfuerzos para mejorar los tratamientos para esta población.
ABSTRACT
OBJECTIVE: This randomized prospective study examines durability of improvement in general symptomatology, psychosocial functioning and interpersonal problems, and compares the long-term efficacy of analytic and systemic group psychotherapy in women 1 year after completion of treatment for childhood sexual abuse. DESIGN AND METHODS: Women (n = 106) randomly assigned to analytic or systemic psychotherapy completed the Symptom Checklist-90-R, Global Assessment of Functioning, Global Life Quality, Registration Chart Questionnaire, and Flashback Registration at pre-treatment, post-treatment, and at a 1-year follow-up. RESULTS: Post-treatment gains were significant for both treatment modalities on all measures, but significantly larger after systemic therapy. Significant treatment response was maintained 1-year post-treatment, but different trajectories were observed: 1 year after treatment completion, improvements for analytic therapy were maintained, whereas they decreased after systemic therapy, resulting in no statistically significant difference in gains between the groups at the 1-year follow-up. Despite maintaining significant gains, more than half of the patients remained above cut-off for caseness concerning general symptomatology at post-treatment and at 1-year follow-up. CONCLUSION: The findings stress the importance of long-term follow-up data in effect studies. Different trajectories were associated with the two treatments, but improvement in the two treatment groups did not differ significantly at the 1-year follow-up. Implications of the difference in trajectories for treatment planning are discussed. PRACTITIONER POINTS: Both analytic and systemic group therapy proved efficient in improving general symptomatology, psychosocial functioning, and interpersonal problems in women with a history of CSA and gains were maintained at a 1-year follow-up. Despite maintaining statistically significant gains at the 1-year follow-up, 54% of the patients remained above the cut-off for caseness with respect to general symptomatology, which may indicate a need for further treatment. Different pre-post follow-up treatment trajectories were observed between the two treatment modalities. Thus, while systemic group therapy showed a significantly better outcome immediately after termination, gains in the systemic treatment group decreased during follow-up, while gains were maintained during follow-up in analytic group therapy.
