The Egyptian Revolution of 2011 resulted in high‐level exposure to sociopolitical violence, placing a large burden on the mental health care system that cannot be effectively met given the small number of available providers in Egypt. We conducted a nonblinded, randomized controlled pilot trial of an online, self‐directed tool for managing posttraumatic stress symptoms (PTSS). The study aimed to evaluate the feasibility, acceptability, and preliminary effectiveness of the PTSD Coach Online–Arabic. Trauma‐exposed Egyptian adults with clinically significant PTSS (N = 87; intervention group: n = 41) completed assessments at baseline, weekly over the treatment period, posttest, and 3‐month follow‐up. Of participants who completed weekly surveys, 88.9% used the program; 22.0% of participants reported regular, weekly use. Most tools received good likeability and perceived benefit scores, but lower perceived benefit scores on three tools suggest that some content may require additional adaptation. Intent‐to‐treat analyses using multilevel modeling with multiple imputation to account for missing data were conducted. Effect sizes for PTSS were below the cutoff for small effects at posttest, d = −0.14, but demonstrated a small positive effect at 3‐months, d = −0.25. There was a small positive effect of treatment on anxiety at posttest, d = −0.37, and a medium effect at 3‐month follow‐up, d = −0.49. Treatment effects for depressed mood were below the cutoff for small effects at posttest and 3‐months, ds = −0.14 and −0.18. These findings suggest that the PTSD Coach Online–Arabic may be a promising supplemental resource for support in this setting.
