Treating posttraumatic stress disorder at home in a single week using 1-week virtual massed cognitive processing therapy.

Posttraumatic stress disorder (PTSD) treatments are increasingly delivered in massed formats and have shown comparable results to standard, weekly treatment. To date, massed cognitive processing therapy (CPT), delivered daily, has been delivered primarily in combination with adjunctive services and among veteran populations, but it has not been rigorously evaluated as a standalone intervention. The present study evaluated 1-week massed CPT delivered virtually (i.e., via telehealth) to a community sample of trauma-exposed individuals (N = 24). Using a single-arm open-label design, participants received CPT twice per day for 5 days. The results indicated that most participants completed treatment (n = 23, 95.8%), and no adverse events were reported. Participants exhibited large reductions in clinician-rated, d = 2.01, and self-reported PTSD symptoms, d = 2.55, as well as self-reported depressive symptoms, d = 1.46. On average, participants reported a 5-point PTSD symptom reduction and 1-point reduction in depressive symptoms for each treatment day. Reductions in PTSD and depressive symptoms were maintained at 3-month follow-up. Overall, 1-week massed CPT delivered virtually was shown to be feasible and to result in rapid symptom reductions that were sustained over time. Virtual massed CPT has the potential to increase access to effective treatments and help trauma survivors restore aspects of their lives in short amounts of time.

Behavioral and neural sensitivity to uncertain threat in individuals with alcohol use disorder: Associations with drinking behaviors and motives.

A developing theory is that individuals with alcohol use disorder (AUD) display exaggerated reactivity to threats that are uncertain (U-threat), which facilitates excessive drinking as a means of avoidance-based coping. There is a promising initial behavioral evidence supporting this theory; however, the neural bases of reactivity to U-threat in individuals with AUD have not been examined. The extent to which biomarkers of U-threat reactivity map onto drinking behaviors and coping motives for alcohol use is also unknown. The current study therefore examined group differences in behavioral and neural reactivity to U-threat in adults with and without AUD. The study also tested whether behavior and brain responses to U-threat correlate with problematic drinking and coping motivated drinking. Volunteers (n = 65) with and without a history of AUD (38 AUD, 27 controls) were included and completed a well-validated threat-of-shock task to probe responses to U-threat and predictable threat (P-threat) while startle eyeblink potentiation was collected. Individuals also completed a newly designed, analogous version of the task during functional magnetic resonance imaging (fMRI). Results indicated that individuals with AUD displayed greater startle magnitude during U-threat, but not P-threat, and greater right insula and dorsal anterior cingulate cortex (dACC) activation during both forms of threat compared with controls. Startle magnitude and insula activation during U-threat positively correlated with self-reported problem drinking and coping motives for alcohol use. Findings demonstrate that individuals with AUD display exaggerated sensitivity to U-threat at the behavioral and neural level and that these multimethod biomarkers tap into negative reinforcement processes of alcohol abuse.

A case series examining PTSD and depression symptom reductions over the course of a 2-week virtual intensive PTSD treatment program for veterans.

OBJECTIVE: Evidence-based treatments for posttraumatic stress disorder (PTSD) can be effectively delivered over telehealth. There are, however, no studies that examine the effectiveness of delivering evidence-based treatments for PTSD in an intensive format via telehealth. Telehealth may be well-suited as a delivery modality because it may address barriers specific to intensive treatments. METHOD: To address this gap, we report on a case series of ten consecutively enrolled veterans (60% male; mean age 42.3, SD = 6.3) who participated in a virtual 2-week, cognitive processing therapy (CPT)-based intensive program. RESULTS: All (100%) participants completed treatment and reported large reductions in PTSD and depression symptoms pre- to posttreatment (Hedge's gws = 2.83 and gws = 1.97, respectively), pre- to 3-month follow-up (Hedge's gws = .99 and gws = 1.24, respectively), as well as very high satisfaction. CONCLUSIONS: Results of this case series suggest that evidence-based treatments for PTSD can be effectively delivered in intensive formats over telehealth and lay the foundation for more rigorously designed and larger scale research comparing virtual to in-person delivered intensive PTSD treatments.

Heightened reactivity to uncertain threat as a neurobehavioral marker of suicidal ideation in individuals with depression and anxiety.

Identifying neurobehavioral correlates of suicidal ideation can help detect those most vulnerable for suicide among high-risk groups, such as those with internalizing psychopathology. Individuals with elevated sensitivity to uncertain threat (U-threat) have a strong preference for known outcomes relative to unknown outcomes and often experience high levels of chronic distress. We therefore hypothesized that among individuals with internalizing psychopathology, those with heightened reactivity to U-threat would be especially prone to suicidal ideation as a means to escape uncertainty. The present study examined whether in two independent samples suicidal ideation was associated with heightened startle response to U-threat, and whether the effects were specific to responses U-threat relative to predictable threat (P-threat). Study 1 was a sample of treatment-seeking patients (N = 99) and Study 2 was a community sample (N = 102). Participants in both samples met current DSM-5 criteria for an anxiety and/or depressive disorder. In Study 1, current suicidal ideation was positively associated with startle potentiation to U-threat. Similarly, in Study 2, a lifetime history of suicidal ideation was positively associated with startle potentiation to U-threat. The relation between suicidal ideation and startle potentiation to U-threat remained when adjusting for number of internalizing diagnoses. Heightened reactivity to U-threat may therefore characterize those with a propensity for suicidal ideation among individuals with internalizing psychopathology.
