Trauma exposure, posttraumatic stress disorder (PTSD), and substance use disorder (SUD) present major threats to public health. PTSD and SUD are major correlates of disability, often resulting in severe social and occupational impairment. Comorbidity between PTSD and SUD (PTSD/SUD) is common and frequently co-occurs with other mental health ailments including depression, anxiety, and suicidality. Comorbidity may be amplified in groups vulnerable to high trauma exposure, such as women with low socioeconomic status including women experiencing homelessness (WEH). Moreover, the reciprocal nature of PTSD/SUD (substances are used to cope with PTSD symptoms; substance use can create high-risk situations for new traumas to occur), can create a cycle of trauma and symptomatology leading to a critical health disparity. PTSD/SUD can be costly and difficult to treat, with treatment completion often low and relapse rates often high. Low-cost, complementary interventions, such as self-compassion (SC) interventions, which target key mechanisms that maintain PTSD/SUD, could improve treatment outcomes. SC interventions include practices that build skills to improve emotional responses, cognitive understanding, and mindfulness. Recent research supports the benefit of SC interventions for reducing PTSD, SUD, and related comorbidities, potentially with large effects. However, sample sizes have generally been small and randomized designs infrequently used. Moreover, while SC interventions may act to improve key mechanisms of treatment response and/or symptom maintenance (e.g., emotion regulation/dysregulation, trauma-related guilt, trauma-related shame, moral injury, and craving), such mediating factors have been underexplored. To address these limitations, the present proposal will implement community-based research principles and use a two phase, mixed-method design to adapt and test a widely used SC intervention (Mindful Self Compassion; MSC) for use with a sample of WEH with PTSD/SUD. The project will be conducted in partnership with a state-funded drug treatment facility that serves women and families experiencing high health disparities. Phase I was completed in 2023 and adapted the standard MSC course for use with trauma-exposed WEH with PTSD/SUD using the ADAPT-ITT model, an eight-stage model that engages community partners to increase feasibility and acceptability of interventions for at-risk populations. Phase II will be an open-label cluster randomized clinical trial (N=202) to test the benefit of the adapted MSC at improving primary (PTSD, substance use) and secondary outcomes (depression, anxiety, hopelessness) among a sample of WEH with PTSD/SUD residing in a residential drug treatment site. MSC (n=101) will be compared to Treatment as Usual (TAU; n=101). WEH in the MSC group will complete a 6-week (six sessions plus a half-day retreat) MSC intervention. The TAU group will engage in weekly check-ins with the research team but will not receive an intervention. WEH will be assessed at baseline, immediately post-intervention, and at a 4-month follow-up. One-on-one interviews will be conducted with the MSC group to collect qualitative data on experiences. An exploratory aim will be to elucidate mechanism of treatment-response and maintenance or remission of PTSD symptoms. These potential mechanisms will include SC, emotion regulation/dysregulation, trauma-related guilt, trauma-related shame, moral injury, and craving. Results may inform treatment for PTSD/SUD in WEH and other groups experiencing high health disparities and provide valuable insights into mechanisms underlying PTSD/SUD symptoms over time. Findings are relevant to military populations, which experience high rates of PTSD/SUD, and other populations disproportionately exposed to trauma.

Taking prescription opioids for pain together with benzodiazepines for the treatment of anxiety disorders is not recommended by the U.S. Food and Drug Administration (FDA) because of the elevated risk of serious complications, including fatal overdose. However, this concurrent prescription use continues to be prevalent, likely due to the high comorbidity between pain and anxiety disorders. Efforts are urgently needed to reduce benzodiazepine use among patients taking opioids. Cognitive behavioral therapy (CBT) is a first-line treatment for anxiety disorders, and represents a safer and more effective treatment for anxiety disorders compared to benzodiazepines. The proposed study aims to make minor adaptations to a CBT protocol to facilitate benzodiazepine tapering and to then conduct a 2-arm randomized clinical trial with primary care patients who receive benzodiazepine and opioid prescriptions. Participants will be randomized to receive a telehealth-delivered intervention consisting of a gentle, 12-week benzodiazepine taper (BZT) with either CBT or a health education control (HE). Participants will be assessed at baseline, several points throughout treatment, at post-treatment, and at a 2-month follow-up assessment on benzodiazepine use, opioid use, and anxiety symptoms. Should CBT + BZT outperform HE + BZT, this intervention could make a significant impact by reducing major consequences of concurrent use of opioids and benzodiazepines, including mortality.

The objective of this research is to assess the effects of engaging in coloring activities on patients' self-reported pain and anxiety scores while they wait to be seen by a physician in an emergency department (ED). The current literature on patient visits in the ED highlights the significance of anxiety, stress, and frustration in patient experiences, especially when accounting for long wait times before the physician-patient encounter. The study will address this common problem by looking at the potential impact of nature-themed or geometric shape coloring activities on the ED patient experience as it relates to self-reported anxiety and pain scores. Given that long wait times are increasingly being reported across the country, this study may offer a possible meaningful low-budget, low-resource intervention which could be offered to patients.

Major depressive disorder (MDD) affects an estimated 350 million people worldwide and is a leading contributor to global disease burden. Commonly used monoamine reuptake-inhibiting treatments for depression are suboptimal, resulting in only 30% of patients achieving remission. This may be because monoamine dysfunction is not the primary pathophysiology in all MDD patients. One avenue for the development of novel MDD treatments is through anti-inflammatory drugs; MDD is linked to a pro-inflammatory phenotype characterized by microglial activation, leading to the release of pro-inflammatory cytokines and upregulation of cellular markers including cyclooxygenase-2 (COX-2) and translocator protein (TSPO; a protein located on the outer membrane of microglia). Relevant to this proposal, TSPO can serve as an in vivo marker of neuroinflammation using the newly developed positron emission tomography (PET) tracer for TSPO, [18F]FEPPA. In support of this, a recent [18F]FEPPA PET study found that MDD patients in a current major depressive episode (MDE) had significantly higher TSPO binding in the prefrontal cortex (PFC), anterior cingulate cortex (ACC) and insula, relative to healthy controls. The prefrontal cortex and ACC are both implicated in mood regulation whereas the insula is involved in interoceptive signaling, which is known to be abnormal in MDD. Celecoxib, a selective COX-2 nonsteroidal anti-inflammatory drug (NSAID), is a promising new treatment for neuroinflammation in MDD. Clinical studies have observed that, in a subset of depressed patients, celecoxib treatment reduced depression severity as assessed by the Hamilton Depression Rating Scale (HDRS). While these findings demonstrate that celecoxib reduces symptom severity, PET imaging technology is critical for understanding how celecoxib affects the underlying pathophysiology of depression. Here, the team will investigate neuroinflammation as an underlying pathology in depression and test whether neuroinflammation is reduced by celecoxib in MDD patients. Specifically, in the proposed pilot study, MDD patients in a current MDE will receive [18F]FEPPA PET scans prior to and following 8 weeks of treatment with 400mg/day of celecoxib, with HDRS scores obtained at each time point. The investigators hypothesize that following celecoxib treatment, patients will show a significant reduction in neuroinflammation in the PFC, ACC and insula, which will correlate positively with the reduction in depressive symptoms, as measured by the HDRS. The proposed study will use novel imaging technology, [18F]FEPPA PET, to measure the effects of celecoxib on neuroinflammation in MDD patients. Our results will help to 1) identify neuroinflammation as an underlying pathology in MDD and 2) test whether reduction of inflammation is the mechanism of action of celecoxib. As such, the results of this study will aid in the development of targeted clinical treatments to improve remission rates in MDD patients.
