This paper examines factors associated with change in PTSD symptom severity among individuals randomised to receive an integrated exposure-based psychotherapy for PTSD and substance dependence-Concurrent Treatment of PTSD and Substance Use Disorders Using Prolonged Exposure (COPE). Outcomes examined include change in PTSD symptom severity as measured by the Clinician Administered PTSD Scale (CAPS), and the reliability and clinical significance of change in PTSD symptom severity. Factors examined include patient baseline characteristics, treatment characteristics, and events over follow-up.

Objective: This article aims to provide supportive guidance for clinicians using the brief behavioral activation treatment for depression - revised (BATD-R) manual. Expanding upon key points less explicitly addressed in the treatment manual, the goal is to convey practical wisdom and clinical nuance beyond that available in the manual, thereby enhancing therapist comfort with the approach and improving treatment delivery.

Methods: In preparation for a randomised control trial of behavioural activation treatment for depression among substance users (the Activate Study), Professor Carl Lejuez, an author on the manual, provided training to our research team.

Introduction And Aims: The high prevalence of trauma exposure and post-traumatic stress disorder (PTSD) among clients of alcohol and other drug (AOD) services is well documented. Less is known, however, about the impact this has on workers who assess and treat such clients. The aim of this study was to examine the prevalence and correlates of secondary traumatic stress (STS) among AOD workers in Australia.

Background: Trauma exposure and post traumatic stress disorder (PTSD) are common among clients of substance use services. Existing treatments for these co-occurring conditions tend to be lengthy, treatment retention is relatively poor, and they require extensive training and clinical supervision. The aim of the present study was to conduct a preliminary examination of the feasibility and acceptability of a brief intervention for PTSD symptoms among individuals seeking substance use treatment.

Context: There is concern that exposure therapy, an evidence-based cognitive-behavioral treatment for posttraumatic stress disorder (PTSD), may be inappropriate because of risk of relapse for patients with co-occurring substance dependence.

Objective: To determine whether an integrated treatment for PTSD and substance dependence, Concurrent Treatment of PTSD and Substance Use Disorders Using Prolonged Exposure (COPE), can achieve greater reductions in PTSD and substance dependence symptom severity compared with usual treatment for substance dependence.

Design, Setting, And Participants: Randomized controlled trial enrolling 103 participants who met DSM-IV-TR criteria for both PTSD and substance dependence.
