Written disclosure treatment for posttraumatic stress disorder in substance use disorder inpatients.

Researchers ran the Pennebaker written-disclosure protocol inside a SUD inpatient unit. Participants wrote about their worst trauma for 20 minutes on three consecutive days. Staff tracked PTSD symptoms before, after, and three months later.

The sample was 45 adults who carried both addiction and clinical PTSD diagnoses. No control group was used.

PTSD scores dropped after the three writing sessions. The gains held steady at the 90-day follow-up. The result was labeled statistically significant.

Luteijn et al. (2020) searched for integrated PTSD-SUD therapy studies in adults with mild ID or borderline IQ and found zero trials. Storch et al. (2012) therefore fills a real-world gap: it shows one low-cost option works in regular SUD wards.

Nosen et al. (2012) looked at craving cues in PTSD-alcohol patients. They found happy moods can spike craving when trauma cues are absent. Their lab data line up with A et al.: treating PTSD (not just addiction) may blunt these mixed emotional triggers.

Zegel et al. (2022) surveyed firefighters and saw that combined PTSD-AUD produces the worst mental-health scores. That survey supports the inpatient study’s core idea — you need to tackle both disorders together.

You can add a three-day writing module to your SUD program tomorrow. No extra meds. No special certs. Just quiet rooms, pens, and a PTSD checklist. If your unit screens for trauma, offer the Pennebaker script as a brief front-loaded intervention. Track scores at intake, week one, and month three to see if the same drop happens for your clients.
