Cannabis use is increasingly prevalent among U.S. veterans, with high rates of both recreational and problematic use. Veterans often use cannabis to manage symptoms associated with mental health problems such as depression and posttraumatic stress disorder (PTSD). Prior work has noted mixed results on the longitudinal associations between cannabis use and depression. Studying these associations at the daily level can lead to improved clarity. <strong>Design</strong>. The present study examined the daily associations between cannabis use and depression in veterans using dynamic structural equation modeling (DSEM). We also explored these associations for those veterans who screened positive for posttraumatic stress disorder (PTSD) compared to those who did not. Setting. All participants were recruited using advertisements from BuildClinical, an NIH approved recruitment vendor. <strong>Participants</strong>. The sample consisted of 74 veterans who provided daily data for 87 consecutive days. <strong>Measurement</strong>. Cannabis was assessed asking how many hours each individual spent high each day, depressed mood was assessed using a sliding scale from not depressed to very depressed each day, and PTSD was assessed using the PTSD checklist. <strong>Findings</strong>. Among the full veteran sample results revealed a bidirectional, negative, association. Specifically, on days when veterans reported greater depression, they reported fewer hours “high” the next day. Conversely, on days when veterans reported a greater number of hours high, they reported less depression the next day. Among veterans screening positive for PTSD, on days when they reported more depression, they reported fewer hours high the next day (no association was noted for cannabis use predicting depression). However, for those who did not screen positive for PTSD, on days when veterans reported greater number of hours high, they reported less depression the next day. <strong>Conclusions</strong>. These results highlight the need for further research on the effect of individual differences in cannabis use patterns among veterans with PTSD on health outcomes. Clinically, these results highlight the importance of targeting the pros and cons of cannabis use for depression symptom relief.

The Brief Religious Coping Scale (Brief RCOPE) is the most commonly used measure of religious coping in the literature; however, relatively little has been reported about the psychometric properties of the brief version. Moreover, the examination of this scale among individuals with a substance use disorder (SUD), a disorder highly associated with major life stressors for which religious coping may serve as a principle form of coping, has been largely overlooked. Therefore, the current study sought to examine the psychometric properties of the Brief RCOPE in a sample of 1290 adults undergoing residential treatment for SUD. Results from confirmatory factor analyses supported the theorized two-factor structure of positive (PRC) and negative (NRC) religious coping, as well as measurement invariance across sex and across time. Validity was established through significant, differential associations between PRC and NRC at pre-treatment and a range of psychosocial outcomes at pre- and post-treatment. This study provides evidence that the Brief RCOPE is a reliable and valid tool for assessing religious coping among adults with SUD.
