Evaluating substance use treatment efficacy for younger and older adults.

The purpose of this study was to examine the differential efficacy of aftercare substance use treatments for younger (below 40, n = 107) versus older (40+, n = 114) adults (N = 221), using data from a randomized controlled trial in a community-based substance abuse treatment center. The younger adult sample had a mean age of 28.9 while the older adult sample had a mean age of 48.

PTSD Symptom Clusters and Craving Differs by Primary Drug of Choice.

Research has demonstrated a cyclical relationship between posttraumatic stress disorder (PTSD) and substance use disorder. Identifying factors that link PTSD symptom clusters and substance use disorder may illuminate mechanisms underlying the PTSD-substance use disorder relationship, better informing interventions that target this comorbidity. The current study of individuals enrolled in an outpatient aftercare chemical dependency program in King County, Washington, assessed whether overall PTSD symptoms and specific PTSD symptom clusters predicted craving depending on individuals identified primary drug of choice (DOC).
