In the August 2019 issue of The Clinical Journal of Pain, in the article by Goldstein et al,1 “The Impact of Psychological Interventions on Posttraumatic Stress Disorder and Pain Symptoms: A Systematic Review and Meta-Analysis,” the effect size (ES) for the randomized clinical trial by Kip, et al that evaluated the ART intervention was incorrectly coded. Instead of indicating a reduction in pain intensity (ES=−1.05, confidence interval [CI]: −1.64, −0.45), it incorrectly indicated an increase in pain intensity (ES=+1.05, CI: 0.45, 1.64). What follows are the corrections to all sections of the manuscript that were impacted by this error. Readers should refer to the updated plot below:

Corrected abstract: Data from 10 RCTs (N=1401; 1033 men) were included in the meta-analysis, which demonstrated a significant effect for reducing pain intensity (ES=−0.33, CI: −0.59, −0.07; P=0.012).

Corrected forest plot Figure 2B on page 5 of the original article: Meta-analysis (N=10) evaluating the overall pooled effect sizes across the included RCTs demonstrated that psychological treatments had a small, statistically significant effect for reducing pain intensity (ES=−0.33, CI: −0.59, −0.07; P=0.012). Psychological-only interventions (n=7 studies) produced a medium, statistically significant pooled effect for reducing pain intensity (ES=−0.51, CI: −0.84, −0.19; P=0.002).

Corrected subgroup analysis of treatment types: Exposure-based therapies (n=3; 207 participants) produced medium, statistically significant pooled effects for reducing pain intensity (ES=−0.60, CI: −1.19, −0.01, P=0.045).

Corrected heterogeneity assessment for pain intensity (refer to corrected Table 5 below): The heterogeneity assessment of the RCTs included in the meta-analysis (n=10) demonstrated moderate, statistically significant heterogeneity among the studies for pain intensity (I2=69.1%; P=0.001).

Corrected implication: The majority of the psychological-only (eg, single modality) RCT interventions demonstrated efficacy for reliably reducing PTSD symptom severity and pain intensity.
