Structured Approach Therapy for Combat-Related PTSD in Returning U.S. Veterans: Complementary Mediation by Changes in Emotion Functioning.
To address the impact of combat-related posttraumatic stress disorder (PTSD) on U. S. Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) veterans, the investigators developed a 12-session manualized PTSD treatment for couples called structured approach therapy (SAT). ⋯ Veterans assigned to the SAT condition showed significantly greater decreases than those assigned to PTSD family education in emotion regulation problems (p < .001, Cohen's f(2) = .18) and fear of intense emotions (p < .001, Cohen's f(2) = .152). Decreases in both emotion regulation problems (mediated effect:ab̂= .36), and fear of intense emotions (mediated effect:ab̂ = .24) were found to be complementary mediators of reductions in PTSD symptoms greater with SAT. These findings suggest that SAT may aid veterans in improving their ability to regulate trauma-related emotions.

Technology-Enhanced Stepped Collaborative Care Targeting Posttraumatic Stress Disorder and Comorbidity After Injury: A Randomized Controlled Trial.
Posttraumatic stress disorder (PTSD) and its comorbidities are endemic among injured trauma survivors. Previous collaborative care trials targeting PTSD after injury have been effective, but they have required intensive clinical resources. The present pragmatic clinical trial randomized acutely injured trauma survivors who screened positive on an automated electronic medical record PTSD assessment to collaborative care intervention (n = 60) and usual care control (n = 61) conditions. ⋯ The covariate adjusted regression was significant: F(2, 204) = 3.06, p = .049. The PTSD intervention effect was greatest at the 3-month (Cohen's effect size d = 0.35, F(1, 204) = 4.11, p = .044) and 6-month (d = 0.38, F(1, 204) = 4.10, p = .044) time points. IT-enhanced collaborative care was associated with modest PTSD symptom reductions and reduced delivery times; the intervention model could potentially facilitate efficient PTSD treatment after injury.

Randomized Controlled Trial
A longitudinal investigation of changes to social resources associated with psychological distress among Kurdish torture survivors living in Northern Iraq.
Social resources can buffer against psychological distress following potentially traumatic events. Psychological distress can also lead to social resource deterioration. This longitudinal study evaluated whether baseline psychological distress symptoms and changes in these symptoms were associated with changes in social resources 5 months later among 96 adult male (52.6%) and female treatment-seeking torture survivors residing in Kurdistan, Iraq. ⋯ For some, higher traumatic grief symptoms were associated with increased social integration (ACOR = 1.17). Increased anxiety (ACOR = 1.23) and PTSD symptoms (ACOR = 1.07) was associated with declines in social contact; decreased depression (ACOR = 1.06) and PTSD symptoms (ACOR = 1.04) were related to gaining social contact. This study highlights the complex relationship between mental health symptoms and losses and gains in social resources among torture survivors.

Randomized Controlled Trial Comparative Study
A randomized clinical trial of cognitive processing therapy for veterans with PTSD related to military sexual trauma.
In this randomized controlled clinical trial, the authors evaluated the effectiveness of cognitive processing therapy (CPT) in the treatment of self-reported and clinician-assessed posttraumatic stress disorder (PTSD) related to military sexual trauma (MST), along with depressive symptoms. Eighty-six veterans (73 female, 13 male) randomly assigned to receive 12 individual sessions of either CPT or present-centered therapy (PCT) were included in analyses. Blinded assessments occurred at baseline, posttreatment, and 2, 4, and 6 months posttreatment. ⋯ All three primary outcome measures improved significantly, both clinically and statistically, across time in both treatment groups. Pre- and posttreatment effect sizes were mostly moderate to large (d = 0.30-1.02) and trended larger in the CPT group. Although the study was impacted by treatment fidelity issues, results provide preliminary evidence for the effectiveness of CPT in reducing self-reported PTSD symptoms in a population of veterans with MST, expanding on established literature that has demonstrated the effectiveness of CPT in treating PTSD related to sexual assault in civilian populations.

Randomized Controlled Trial
The efficacy of early propranolol administration at reducing PTSD symptoms in pediatric injury patients: a pilot study.
Initial research supports the use of propranolol to prevent posttraumatic stress disorder (PTSD); research has not examined pharmacological prevention for children. Twenty-nine injury patients (ages 10-18 years old) at risk for PTSD were randomized to a double-blind 10-day trial of propranolol or placebo initiated within 12 hours postadmission. ⋯ Whereas girls receiving propranolol reported more PTSD symptoms relative to girls receiving placebo, Delta R(2) = .44, boys receiving propranolol showed a nonsignificant trend toward fewer PTSD symptoms than boys receiving placebo, Delta R(2) = .32. Findings inform gender differences regarding pharmacological PTSD prevention in youth.
