Anxiety Sensitivity Among Trauma-Exposed Non-Hispanic Black Adults: Relations to Posttraumatic Stress.

ABSTRACT: The non-Hispanic Black population experiences trauma-related disparities. One potentially important individual difference construct for posttraumatic stress is anxiety sensitivity. There is limited work on anxiety sensitivity among non-Hispanic Black persons, and no research has focused on this construct in terms of posttraumatic stress among this population. This study sought to build on this limited knowledge by exploring whether this construct was uniquely associated with more severe posttraumatic stress among this population. Participants included non-Hispanic Black trauma-exposed adults ( N = 121; Mage = 21.79 years). Results indicated that anxiety sensitivity was related to more severe overall posttraumatic stress and greater severity of each posttraumatic stress symptom cluster; all effects were evident after adjusting for the variance accounted for by age, sex, education, subjective social status, neuroticism, and number of traumatic event types experienced (lifetime). The study provides the first empirical evidence that, among a trauma-exposed non-Hispanic Black sample of adults, anxiety sensitivity is related to more severe posttraumatic stress symptoms. This intraindividual difference factor could be a focus of intervention programming for this trauma disparity population.

Posttraumatic stress among trauma-exposed Hispanic/Latinx adults: relations to mental health.

Latinx persons are exposed to higher rates of traumatic events and conditional risks for developing posttraumatic stress disorder (PTSD) symptoms and comorbid mental health symptoms compared to other minority groups. The study evaluated PTSD symptom severity for global and specific cluster severity relating to co-occurring anxiety, social anxiety, depression, and suicidal ideation among 326 Latinx adults who endorsed trauma exposure. Results indicated that global PTSD symptom severity was significantly related to greater social anxiety, anxious arousal, depression, and suicidal ideation symptoms. PTSD arousal and reactivity symptom cluster had the strongest relation to anxious arousal, social anxiety, and depression, whereas negative alterations in cognitions and mood symptoms had the strongest association with social anxiety, depression, and suicidal ideation. The findings suggest that global PTSD symptom severity, alongside arousal and reactivity and negative alterations in cognitions and mood, are related to a range of concurrent negative mental health symptoms among trauma exposed Latinx young adults.

Cognitive behavioral therapy (CBT) plus attention bias modification (ABM) reduces anxiety sensitivity and depressive symptoms in panic disorder: A pilot randomized trial.

BACKGROUND: Cognitive bias theories propose that reducing threat hypervigilance in mental disorders can augment cognitive behavioral therapy (CBT) outcomes. However, no studies have tested whether adding attention bias modification (ABM) can effectively enhance CBT's effects on anxiety sensitivity (AS), electromyography (EMG), and skin conductance (SC) for panic disorder (PD). This pilot randomized controlled trial (RCT) thus aimed to evaluate the efficacy of CBT + ABM (vs. CBT plus attention training placebo; PBO) on those outcomes. METHOD: This study is a secondary analysis (Baker et al., 2020). Adults with PD were randomized to receive CBT + ABM (n = 11) or CBT + PBO (n = 12). Before each of the first five CBT sessions, CBT + ABM and CBT + PBO participants completed a 15-min ABM task or attention training PBO, respectively. AS and depression severity as well as SC and EMG during habituation to a loud-tone startle paradigm were assessed. Hierarchical Bayesian analyses were conducted. RESULTS: During pre-post-treatment and pre-follow-up, CBM + ABM (vs. CBT + PBO) led to a notably greater reduction in ASI-Physical (between-group d = -1.26 to -1.25), ASI-Cognitive (d = -1.16 to -1.10), and depression severity (d = -1.23 to -0.99). However, no between-group difference was observed for ASI-Social, EMG, or SC indices. DISCUSSION: Adding a brief computerized ABM intervention to CBT for PD protocols may enhance therapeutic change.

Anxiety sensitivity in relation to post-traumatic stress disorder symptom clusters among young adults with probable post-traumatic stress disorder.

Despite the promise of past research on anxiety sensitivity (AS) and posttraumatic stress, extant work is limited, given (1) most studies consist of non-Hispanic White and middle-aged samples, (2) few have demonstrated incremental validity to general emotional traits and social determinants of health, and (3) limited work has characterized how AS relates to specific Posttraumatic Stress Disorder (PTSD) symptom clusters among those with (probable) PTSD. The current study evaluated the role of AS in relation to PTSD symptom clusters among a racially/ethnically diverse sample of young adults with probable PTSD. Participants included young adults who met the clinical cut-off for probable PTSD per the Posttraumatic Diagnostic Scale. Results indicated that AS was significantly related to overall posttraumatic stress symptom severity; the effect was evident after adjusting for a range of covariates including neuroticism and subjective social status. AS also was incrementally associated with arousal and hyperreactivity, changes in mood and cognition, and intrusion PTSD symptom clusters. In contrast to expectation, no effect for AS was evident for the avoidance PTSD symptom cluster. The current data uniquely add to the existing AS PTSD literature by showcasing distinct symptom cluster patterns among a racially/ethnically diverse sample of young adults with probable PTSD.

Distress overtolerance among firefighters: Associations with posttraumatic stress.

OBJECTIVE: Firefighters experience heightened rates of posttraumatic stress disorder (PTSD) symptoms compared to the general population. Nascent literature has identified distress overtolerance (DO; i.e., the tendency to persist through extremely high levels of distress despite harmful consequences) as a construct of potential relevance to PTSD symptomatology, though empirical research is lacking. The present study examined incremental associations between DO subscales (Capacity for Harm: persevering through distress despite its effect on 1's wellbeing; Fear of Negative Evaluation: persisting through distress due to a fear of being negatively evaluated by others should they quit) and PTSD symptom severity and symptom cluster severity (i.e., intrusion, avoidance, negative alterations in cognitions and mood [NACM], arousal and reactivity) among firefighters. METHOD: Participants included 282 trauma-exposed firefighters (91.8% male, Mage = 40.4, SD = 9.6). Covariates included years in the fire service, trauma load (i.e., number of trauma exposure types), and negative affect. RESULTS: Results indicated that Capacity for Harm was a significant incremental correlate of total PTSD symptom severity (ΔR² = .045, p = .004), NACM symptoms (ΔR² = .061, p < .001), and arousal/reactivity symptoms (ΔR² = .047, p = .005). Fear of Negative Evaluation was not significantly related to any criterion variables. CONCLUSION: Further work examining DO-PTSD relations is necessary to inform intervention and policy for the fire service. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
