Background It is unclear whether people with post-traumatic stress disorder (PTSD) and symptoms of complex PTSD due to childhood abuse need a treatment approach different from approaches in the PTSD treatment guidelines. Aims To determine whether a phase-based approach is more effective than an immediate trauma-focused approach in people with childhood-trauma related PTSD (Netherlands Trial Registry no.: NTR5991). Method Adults with PTSD following childhood abuse were randomly assigned to either a phase-based treatment condition (8 sessions of Skills Training in Affect and Interpersonal Regulation (STAIR), followed by 16 sessions of eye-movement desensitisation and reprocessing (EMDR) therapy; n = 57) or an immediately trauma-focused treatment condition (16 sessions of EMDR therapy; n = 64). Participants were assessed for symptoms of PTSD and complex PTSD, and other forms of psychopathology before, during and after treatment and at 3- and 6-month follow-ups. Results Data were analysed with linear mixed models. No significant differences between the two treatments on any variable at post-treatment or follow-up were found. Post-treatment, 68.8% no longer met PTSD diagnostic criteria. Self-reported PTSD symptoms significantly decreased for both STAIR–EMDR therapy (d = 0.93) and EMDR therapy (d = 1.54) from pre- to post-treatment assessment, without significant difference between the two conditions. No differences in drop-out rates between the conditions were found (STAIR–EMDR 22.8% v. EMDR 17.2%). No study-related adverse events occurred. Conclusions This study provides compelling support for the use of EMDR therapy alone for the treatment of PTSD due to childhood abuse as opposed to needing any preparatory intervention.
BackgroundThe treatment of posttraumatic stress disorder (PTSD) related to a history of sexual and/or physical abuse in childhood is the subject of international debate, with some favouring a phase-based approach as their preferred treatment, while others argue for immediate trauma-focused treatment. A history of (chronic) traumatisation during childhood has been linked to the development of distinct symptoms that are often labelled as symptoms of complex PTSD. Many therapists associate the presence of symptoms of complex PTSD with a less favourable treatment prognosis. The purpose of this study is to determine whether a phase-based approach is more effective than stand-alone trauma-focused therapy in individuals with PTSD and possible symptoms of complex PTSD resulting from a history of repeated sexual and/or physical abuse in childhood. An additional aim is to investigate moderators, predictors of treatment (non) response and drop-out.MethodThe sample consists of patients between 18 and 65 years old with a diagnosis of PTSD who report a history of repeated sexual and/or physical abuse in childhood (N = 122). Patients will be blindly allocated to either 16 sessions of eye movement desensitization and reprocessing (EMDR) therapy preceded by a stabilization phase (eight sessions of Skills Training in Affect and Interpersonal Regulation (STAIR)) or only 16 sessions of EMDR therapy. Assessments are carried out pre-treatment, after every eighth session, post-treatment, and at 3 and 6 months follow up. The main parameter will be the severity of PTSD symptoms (PTSD Symptoms Scale-Self Report). Secondary outcome variables are the presence of a PTSD diagnosis (Clinician-Administered PTSD Scale for DSM-5), severity of complex PTSD symptoms (Structured Interview for Disorders of Extreme Stress-Revised and symptoms-specific questionnaires), changes in symptoms of general psychopathology (Brief Symptom Inventory), and quality of life (Euroqol-5D). Health care consumption and productivity loss in patients will also be indexed.DiscussionThe study results may help to inform the ongoing debate about whether a phase-based approach has added value over immediate trauma-focused therapy in patients suffering from PTSD due to childhood abuse. Furthermore, the results will contribute to knowledge about the safety, efficacy, and cost-effectiveness of treatments in this target group.Trial registrationNederlands Trialregister, NTR5991.

BackgroundKnowledge about patient characteristics predicting treatment dropout for post-traumatic stress disorder (PTSD) is scarce, whereas more understanding about this topic may give direction to address this important issue.MethodData were obtained from a randomized controlled trial in which a phase-based treatment condition (Eye Movement Desensitization and Reprocessing [EMDR] therapy preceded by Skills Training in Affect and Interpersonal Regulation [STAIR]; n = 57) was compared with a direct trauma-focused treatment (EMDR therapy only; n = 64) in people with a PTSD due to childhood abuse. All pre-treatment variables included in the trial were examined as possible predictors for dropout using machine learning techniques.ResultsFor the dropout prediction, a model was developed using Elastic Net Regularization. The ENR model correctly predicted dropout in 81.6% of all individuals. Males, with a low education level, suicidal thoughts, problems in emotion regulation, high levels of general psychopathology and not using benzodiazepine medication at screening proved to have higher scores on dropout.ConclusionOur results provide directions for the development of future programs in addition to PTSD treatment or for the adaptation of current treatments, aiming to reduce treatment dropout among patients with PTSD due to childhood abuse.
