Predictors and moderators of treatment outcome for single incident paediatric PTSD: a multi-centre randomized clinical trial.

Background: With few RCTs having compared active treatments for paediatric PTSD, little is known about whether or which baseline (i.e. pre-randomization) variables predict or moderate outcomes in the evaluated treatments. Objective: To identify predictors and moderators of paediatric PTSD outcomes for Eye Movement Desensitization and Reprocessing Therapy (EMDR) and Cognitive Behavioural Writing Therapy (CBWT). Method: Data were obtained as part of a multi-centre, randomized controlled trial of up to six sessions (up to 45 minutes each) of either EMDR therapy, CBWT, or wait-list, involving 101 youth (aged 8-18 years) with a PTSD diagnosis (full/subthreshold) tied to a single event. The predictive and moderating effects of the child's baseline sociodemographic and clinical characteristics, and parent's psychopathology were evaluated using linear mixed models (LMM) from pre- to post-treatment and from pre- to 3- and 12-month follow-ups. Results: At post-treatment and 3-month follow-up, youth with an index trauma of sexual abuse, severe symptoms of PTSD, anxiety, depression, more comorbid disorders, negative posttraumatic beliefs, and with a parent with more severe psychopathology fared worse in both treatments. For children with more severe self-reported PTSD symptoms at baseline, the (exploratory) moderator analysis showed that the EMDR group improved more than the CBWT group, with the opposite being true for children and parents with a less severe clinical profile. Conclusions: The most consistent finding from the predictor analyses was that parental symptomatology predicted poorer outcomes, suggesting that parents should be assessed, supported and referred for their own treatment where indicated. The effect of the significant moderator variables was time-limited, and given the large response rate (>90%) and brevity (<4 hours) of both treatments, the present findings suggest a focus on implementation and dissemination, rather than tailoring, of evidence-based trauma-focused treatments for paediatric PTSD tied to a single event.

Antecedentes: Dado que pocos ECA (ensayos controlados aleatorizados) han comparado tratamientos activos para el TEPT pediátrico, se sabe poco acerca de si las variables basales (es decir, pre-aleatorización) predicen o moderan los resultados en los tratamientos evaluados.Objetivo: Identificar predictores y moderadores de los resultados del TEPT pediátrico para la Terapia de Reprocesamiento y Desensibilización por Movimientos Oculares (EMDR) y la Terapia de Escritura Cognitiva Conductual (CBWT en sus siglas en ingles).Método: Los datos se obtuvieron como parte de un ensayo controlado aleatorizado multicéntrico de hasta seis sesiones (de hasta 45 minutos cada una) de terapia EMDR, CBWT o lista de espera, que incluyó a 101 jóvenes (de 8 a 18 años de edad) con un diagnóstico de TEPT (total/subumbral) vinculado a un solo evento. Los efectos predictivos y moderadores de las características sociodemográficas y clínicas basales del niño y la psicopatología de los padres se evaluaron mediante modelos lineales mixtos (MLM) desde antes y después del tratamiento y desde antes hasta los 3 y 12 meses de seguimiento.Resultados: En el post-tratamiento y en el seguimiento a los 3 meses, los jóvenes con un trauma índice de abuso sexual, síntomas severos de TEPT, ansiedad, depresión, más trastornos comórbidos, creencias postraumáticas negativas y con un padre con psicopatología más severa obtuvieron los peores resultados en ambos tratamientos. Para los niños con síntomas de TEPT auto-informados más graves al inicio del estudio, el análisis del moderador (exploratorio) mostró que el grupo EMDR mejoró más que el grupo CBWT, siendo lo opuesto para los niños y los padres con un perfil clínico menos grave.Conclusiones: El hallazgo más consistente de los análisis de predictores fue que la sintomatología de los padres predijo peores resultados, lo que sugiere que los padres deben ser evaluados, apoyados y referidos para su propio tratamiento cuando esté indicado. El efecto de las variables moderadoras significativas fue limitado en el tiempo, y dada la gran tasa de respuesta (> 90%) y la brevedad (<4 horas) de ambos tratamientos, los presentes hallazgos sugieren un enfoque en la implementación y diseminación, en lugar de la adaptación, de tratamientos centrados en el trauma basados en la evidencia para el TEPT pediátrico vinculados a un solo evento.

Comparison of eye movement desensitization and reprocessing therapy, cognitive behavioral writing therapy, and wait-list in pediatric posttraumatic stress disorder following single-incident trauma: a multicenter randomized clinical trial.

BACKGROUND: Practice guidelines for childhood posttraumatic stress disorder (PTSD) recommend trauma-focused psychotherapies, mainly cognitive behavioral therapy (CBT). Eye movement desensitization and reprocessing (EMDR) therapy is a brief trauma-focused, evidence-based treatment for PTSD in adults, but with few well-designed trials involving children and adolescents. METHODS: We conducted a single-blind, randomized trial with three arms (n = 103): EMDR (n = 43), Cognitive Behavior Writing Therapy (CBWT; n = 42), and wait-list (WL; n = 18). WL participants were randomly reallocated to CBWT or EMDR after 6 weeks; follow-ups were conducted at 3 and 12 months posttreatment. Participants were treatment-seeking youth (aged 8-18 years) with a DSM-IV diagnosis of PTSD (or subthreshold PTSD) tied to a single trauma, who received up to six sessions of EMDR or CBWT lasting maximally 45 min each. RESULTS: Both treatments were well-tolerated and relative to WL yielded large, intent-to-treat effect sizes for the primary outcomes at posttreatment: PTSD symptoms (EMDR: d = 1.27; CBWT: d = 1.24). At posttreatment 92.5% of EMDR, and 90.2% of CBWT no longer met the diagnostic criteria for PTSD. All gains were maintained at follow-up. Compared to WL, small to large (range d = 0.39-1.03) intent-to-treat effect sizes were obtained at posttreatment for negative trauma-related appraisals, anxiety, depression, and behavior problems with these gains being maintained at follow-up. Gains were attained with significantly less therapist contact time for EMDR than CBWT (mean = 4.1 sessions/140 min vs. 5.4 sessions/227 min). CONCLUSIONS: EMDR and CBWT are brief, trauma-focused treatments that yielded equally large remission rates for PTSD and reductions in the severity of PTSD and comorbid difficulties in children and adolescents seeking treatment for PTSD tied to a single event. Further trials of both treatments with PTSD tied to multiple traumas are warranted.

Nonpharmacological interventions for ADHD: systematic review and meta-analyses of randomized controlled trials of dietary and psychological treatments.

OBJECTIVE: Nonpharmacological treatments are available for attention deficit hyperactivity disorder (ADHD), although their efficacy remains uncertain. The authors undertook meta-analyses of the efficacy of dietary (restricted elimination diets, artificial food color exclusions, and free fatty acid supplementation) and psychological (cognitive training, neurofeedback, and behavioral interventions) ADHD treatments. METHOD: Using a common systematic search and a rigorous coding and data extraction strategy across domains, the authors searched electronic databases to identify published randomized controlled trials that involved individuals who were diagnosed with ADHD (or who met a validated cutoff on a recognized rating scale) and that included an ADHD outcome. RESULTS: Fifty-four of the 2,904 nonduplicate screened records were included in the analyses. Two different analyses were performed. When the outcome measure was based on ADHD assessments by raters closest to the therapeutic setting, all dietary (standardized mean differences=0.21-0.48) and psychological (standardized mean differences=0.40-0.64) treatments produced statistically significant effects. However, when the best probably blinded assessment was employed, effects remained significant for free fatty acid supplementation (standardized mean difference=0.16) and artificial food color exclusion (standardized mean difference=0.42) but were substantially attenuated to nonsignificant levels for other treatments. CONCLUSIONS: Free fatty acid supplementation produced small but significant reductions in ADHD symptoms even with probably blinded assessments, although the clinical significance of these effects remains to be determined. Artificial food color exclusion produced larger effects but often in individuals selected for food sensitivities. Better evidence for efficacy from blinded assessments is required for behavioral interventions, neurofeedback, cognitive training, and restricted elimination diets before they can be supported as treatments for core ADHD symptoms.

The Effectiveness of Mindfulness Training for Children with ADHD and Mindful Parenting for their Parents.

This study evaluated the effectiveness of an 8-week mindfulness training for children aged 8-12 with ADHD and parallel mindful parenting training for their parents. Parents (N = 22) completed questionnaires on their child's ADHD and ODD symptoms, their own ADHD symptoms, parenting stress, parental overreactivity, permissiveness and mindful awareness before, immediately after the 8-week training and at 8-week follow-up. Teachers reported on ADHD and ODD behavior of the child. A within-group waitlist was used to control for the effects of time and repeated measurement. Training was delivered in group format. There were no significant changes between wait-list and pre-test, except on the increase of teacher-rated ODD behavior. There was a significant reduction of parent-rated ADHD behavior of themselves and their child from pre-to posttest and from pre- to follow-up test. Further, there was a significant increase of mindful awareness from pre-to posttest and a significant reduction of parental stress and overreactivity from pre-to follow-up test. Teacher-ratings showed non-significant effects. Our study shows preliminary evidence for the effectiveness of mindfulness for children with ADHD and their parents, as rated by parents. However, in the absence of substantial effects on teacher-ratings, we cannot ascertain effects are due to specific treatment procedures.
