Interventional Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT04021329). This is a study registration, not published results. Lead sponsor: Khushal Khan Khattak Univeristy, Karak, Pakistan. Recruitment status: COMPLETED. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 100 participants (ACTUAL). Conditions: Efficacy of Psychotherapy. Interventions: BEHAVIORAL: CBT Therapy. Primary outcome measures: Measurement of Change in the symptoms of Post Traumatic Stress Disorder , 1st week (Baseline/pre-treatment screening, T-1); six weeks (during treatment screening, T-2); 12 weeks (post-treatment assessment, T-3). Finally, three months (follow up assessment, T-4).; Measurement of Socio Demographic Profile , 1st week at start of treatment, i.e, from date of randomization. Brief summary: Post-Traumatic Stress Disorder(PTSD) develops after exposure to or witnessing traumatic events. PTSD is highly comorbid and individuals with PTSD usually report Major Depressive Disorder(MDD). Common treatment choices for PTSD and MDD are either EMDR or CBT, however, little is known about their comparative efficacy, especially in Pakistan. Therefore, this Randomized Controlled Trial(RCT) aims at determining the comparative efficacy of EMDR vs CBT in Pakistan. This study will also examine the association between reduction in symptoms of PTSD and MDD over course of treatment. In this regard, two arms Crossover Randomized Controlled Trial(RCT) with Repeated Measures Design will be selected. This study will be conducted at two rehabilitation centres and patients will be screened at Time:01, baseline; Time:02, during treatment; Time:03, post treatment and Time:04, 06 months follow-up. All analyses will be performed according to intention-to-treat principle. Variations in symptoms will be analysed by using descriptive statistics, χ2 tests, t-tests, and one way ANOVA. To examine changes in PTSD and MDD across time and to check efficacy of each treatment, a series of Linear Mixed Models will be run. Furthermore, a series of multi-level lagged mediation analysis will be performed to check bi-directional mediation between changes PTSD and MDD over time. This protocol has outlined the rationale for determining efficacy of EMDR and CBT in Pakistan. It will help in answering a broad range of questions concerning efficacy of newly developed evidence-based treatments. Moreover, it may also guide future research on the treatment of PTSD and MDD in the developing countries.
