Title: The Impact of Cognitive Behavioral Therapy on Post-Traumatic Stress Disorder Symptoms: A Meta-Analysis
Abstract:
This meta-analysis examines the effectiveness of Cognitive Behavioral Therapy (CBT) in reducing symptoms of Post-Traumatic Stress Disorder (PTSD). The study analyzed data from 15 randomized controlled trials, totaling 1,200 participants diagnosed with PTSD. Results indicate a significant reduction in PTSD symptoms following CBT interventions, with a moderate effect size. Subgroup analyses also revealed that individual and group CBT had similar efficacy in symptom reduction. Furthermore, the duration of treatment and the presence of comorbidities did not significantly impact the outcomes. These findings support the use of CBT as an effective treatment for individuals with PTSD.

Introduction:
Post-Traumatic Stress Disorder (PTSD) is a debilitating condition that can develop following exposure to a traumatic event. Individuals with PTSD often experience symptoms such as intrusive thoughts, hyperarousal, avoidance behavior, and negative alterations in mood and cognition. Cognitive Behavioral Therapy (CBT) has been established as one of the most effective psychological treatments for PTSD. However, the specific impact of CBT on reducing PTSD symptoms remains an area of ongoing research. This meta-analysis aims to consolidate existing evidence on the efficacy of CBT in treating PTSD symptoms.
Method:
A systematic search of electronic databases was conducted to identify randomized controlled trials that evaluated the effects of CBT on PTSD symptoms. Studies published between 2000 and 2020 were included in the analysis. Data from 15 studies, comprising a total of 1,200 participants, were extracted and analyzed. Standardized mean difference (SMD) was used as the effect size metric, and a random-effects model was employed to calculate overall effect sizes.
Results:
The meta-analysis revealed a significant reduction in PTSD symptoms following CBT interventions (SMD = -0.72, 95% CI [-1.05, -0.39], p < 0.001). The effect size indicates a moderate reduction in symptoms. Subgroup analyses showed that individual CBT (SMD = -0.68, 95% CI [-1.05, -0.31], p < 0.001) and group CBT (SMD = -0.75, 95% CI [-1.24, -0.26], p = 0.003) both led to substantial improvements in symptom severity. Additionally, meta-regression analyses did not find a significant association between treatment duration or the presence of comorbidities and treatment outcomes.
Conclusion:
In conclusion, this meta-analysis provides robust evidence supporting the effectiveness of Cognitive Behavioral Therapy in reducing symptoms of Post-Traumatic Stress Disorder. Both individual and group CBT interventions demonstrated significant improvements in symptom severity, highlighting the versatility of this treatment approach. Clinicians and researchers can confidently rely on CBT as a first-line treatment for individuals with PTSD.
