Limitations
PTSD
This study had several limitations. Most of the active duty military and veteran participants were recruited from Texas and may not represent the entire US population of service members and veterans. Because of ethical concerns about not treating all participants, this trial compared 2 compressed formats of PE delivery and did not include a waiting list control, placebo, or an alternative inactive treatment. Therefore, additional research is needed to determine the comparative efficacy of compressed PE and to match participants to treatments to help attain even greater treatment efficacy. In addition, daily compressed PTSD treatments delivered over 2 to 3 weeks are not feasible for all individuals. However, the results of this study are consistent with other research showing that compressed treatment formats result in more patients completing treatment, reduced treatment dropouts, and overall improved outcomes.
