A culturally adapted unified protocol for transdiagnostic treatment of anxiety disorders in adolescents (UP-A): a randomized waitlist-controlled trial.

BACKGROUND: Anxiety disorders are highly prevalent and debilitating conditions that show high comorbidity rates in adolescence. The present article illustrates how Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Adolescents (UP-A) was adapted for Iranian adolescents with anxiety disorders. METHODS: A total of 54 adolescents with comorbid anxiety disorders participated in a randomized, waitlist-controlled trial of group weekly sessions of either UP-A or waitlist control (WLC). Primary and process of change outcomes were assessed at baseline, posttreatment, and 1-month follow-up. RESULTS: Significant changes were observed over time on major DSM-5 anxiety disorder symptoms (F(2, 51) = 117.09, p < 0.001), phobia type symptoms (F(2, 51) = 100.67, p < 0.001), and overall anxiety symptoms (F(2, 51) = 196.29, p < 0.001), as well as on emotion regulation strategies of reappraisal (F(2, 51) = 17.03, p < 0.001), and suppression (F(2, 51) = 21.13, p < 0.001), as well as on intolerance of uncertainty dimensions including prospective (F(2, 51) = 74.49, p < 0.001), inhibitory (F(2, 51) = 45.94, p < 0.001), and total intolerance of uncertainty (F(2, 51) = 84.42, p < 0.001), in favor of UP-A over WLC. CONCLUSION: Overall, results provide a cultural application of the UP-A and support the protocol as useful for improving anxiety disorders as well as modifying of emotion regulation strategies and intolerance of uncertainty dimensions in Iranian adolescents. Future directions and study limitations are discussed.

Anxiety sensitivity and COVID-19 mental health, fatigue, and well-being: a longitudinal examination among adults from the United States during March-October 2020.

There is widespread empirical evidence that the COVID-19 pandemic contributed to elevated risk of mental and physical health symptoms and decreased quality of life. The present investigation sought to examine if individual differences in anxiety sensitivity was associated with mental health, psychosomatic, and well-being among a sample of US adults during a 6-month period early in the COVID-19 pandemic. Employing longitudinal research methodology, we tested the hypothesis that the anxiety sensitivity global factor would be related to increased risk of anxiety, depression, fatigue, and lower well-being. Secondary analyses evaluated the lower order anxiety sensitivity factors for the same criterion variables. The sample consisted of 778 participants with an average age of 37.96 (SD = 11.81; range 18-73). Results indicated that, as hypothesized, anxiety sensitivity was associated with increased risk for more severe anxiety, depression, fatigue, and lesser well-being; the observed effects of anxiety sensitivity were relatively robust and evident in adjusted models that controlled for numerous theoretically and clinically relevant factors (e.g. perceived health status). Overall, these results suggest that pandemic functioning could likely be improved via interventions that target elevated anxiety sensitivity as a vulnerability factor for a broad range of aversive psychosomatic symptoms and personal well-being.

Intraindividual change in pain tolerance and negative affect over 20 years: findings from the MIDUS study.

Pain tolerance, defined as the ability to withstand physical pain states, is a clinically important psychobiological process associated with several deleterious outcomes, including increased pain experience, mental health problems, physical health problems, and substance use. A significant body of experimental work indicates that negative affect is associated with pain tolerance, such that increased negative affect is associated with decreased pain tolerance. Although research has documented the associations between pain tolerance and negative affect, little work has examined these associations over time, and how change in pain tolerance is related to changes in negative affect. Therefore, the current study examined the relationship between intraindividual change in self-reported pain tolerance and intraindividual change in negative affect over 20 years in a large, longitudinal, observation-based national sample of adults (n = 4,665, Mage = 46.78, SD =12.50, 53.8% female). Results from parallel process latent growth curve models indicated that slope of pain tolerance and negative affect were associated with each other over time (r = .272, 95% CI [.08, .46] p = .006). Cohen's d effect size estimates provide initial, correlational evidence that changes in pain tolerance may precede changes in negative affect. Given the relevance of pain tolerance to deleterious health outcomes, better understanding how individual difference factors, including negative affect, influence pain tolerance over time, are clinically important to reduce disease-related burden.

Associations of resilience and hope with mental and physical health among firefighters.

OBJECTIVE: Firefighters represent an understudied population with high rates of chronic exposure to stress and potentially traumatic events. Thus, there is a need to identify modifiable resilience factors to address posttraumatic stress disorder (PTSD) symptoms (PTSD) and chronic pain in firefighters to inform prevention and intervention efforts. METHODS: The current sample included 155 firefighters (93.5% male; Mage = 42.2, SD = 9.8) recruited online from career, volunteer, and combination (i.e., volunteer and career) departments in a large metropolitan area in the southern United States. RESULTS: Structural equation modeling (SEM) was used to investigate the associations between/among resilience and hope on PTSD symptoms, chronic pain, well-being, and posttraumatic growth (PTG). Resilience had a stronger, negative relationship with PTSD and chronic pain compared to hope, while hope had a stronger, positive relationship with PTG and well-being compared to resilience. Hope and resilience combined predicted 10%-33% of the variance in the outcomes. CONCLUSION: The current findings may provide evidence to promote interventions that increase resilience and hope in firefighters.

Hope, optimism, and self-efficacy predicting mental health and illness in a community sample exposed to Hurricane Harvey.

In 2017, Hurricane Harvey flooded more than 300,000 buildings causing an estimated $125 billion in damages and resulting in 68 deaths (National Hurricane Center). This actual or threatened loss of life and physical harm led many to report negative effects on mental well-being and greater mental illness. However, many individuals have been able to experience similar adverse events without a significant negative impact on their mental health and well-being. Positive thinking factors such as hope, optimism, and self-efficacy have been proposed as protective factors in the face of difficult life events. Hope, optimism, and self-efficacy are related but distinct constructs that have often been studied separately, but whose unique impact on well-being and mental illness is less clear, especially in the context of a natural hazard. The current study uses structural equation modeling to measure the unique contribution of hope, optimism, and hurricane-coping self-efficacy on mental well-being and mental illness in a community sample of 300 subjects who experienced Hurricane Harvey, recruited from Mechanical Turk.

"Do I Have a Memory Problem? I Can't Recall": An Evaluation of Measurement Invariance in Subjective Reporting of Memory Symptoms among Persons with and without Objective HIV-Associated Memory Impairment.

OBJECTIVE: Memory symptoms and objective impairment are common in HIV disease and are associated with disability. A paradoxical issue is that objective episodic memory failures can interfere with accurate recall of memory symptoms. The present study assessed whether responses on a self-report scale of memory symptoms demonstrate measurement invariance in persons with and without objective HIV-associated memory impairment. METHOD: In total, 505 persons with HIV completed the Prospective and Retrospective Memory Questionnaire (PRMQ). Objective memory impairment (n = 141) was determined using a 1-SD cutoff on clinical tests of episodic memory. PRMQ measurement invariance was assessed by confirmatory factor analyses examining a one-factor model with increasing cross-group equality constraints imposed on factor loadings and item thresholds (i.e., configural, weak, and strong invariance). RESULTS: Configural model fit indicated that identical items measured a one-factor model for both groups. Comparison to the weak model indicated that factor loadings were equivalent across groups. However, there was evidence of partial strong invariance, with two PRMQ item thresholds differing across memory impairment groups. Post hoc analyses using a 1.5-SD memory impairment cutoff (n = 77) revealed both partial weak and partial strong invariance, such that PRMQ item loadings differed across memory groups for three items. CONCLUSIONS: The PRMQ demonstrated a robust factor structure among persons with and without objective HIV-associated memory impairment. However, on select PRMQ items, individuals with memory impairment reported observed scores that were relatively higher than their latent score, while items were more strongly associated with the memory factor in a group with greater memory impairment.

Suppression and acceptance in unipolar depression: Short-term and long-term effects on emotional responding.

OBJECTIVES: Transdiagnostic treatments increasingly include emotion regulation training focused on use of emotional suppression and acceptance. Despite the frequent use of these treatments in depression, little is known about the effects of these strategies in this population. DESIGN: An experimental study. METHODS: Eighty Veterans with unipolar depression participated in a study examining effects of these strategies on emotional responding (subjective, behavioural, and physiological). Physiological measures included: heart rate (HR), respiration (Resp), skin conductance (SC), and corrugator electromyography. On Day 1, participants were randomised to one of three conditions (acceptance, suppression, or control) and underwent an autobiographical sad mood induction. On Day 2, participants underwent a similar mood induction one week later. RESULTS: The suppression group demonstrated reduced physiological reactivity (Resp and SC) on Day 1. However, the suppression group reported decreased positive affect on Day 2. CONCLUSIONS: Results support short-term effectiveness and longer term costs from suppression use among depressed individuals. Findings may inform application of transdiagnostic emotion regulation treatments and suggest suppression functions differently in depressed versus other clinical populations.

The explanatory role of fatigue severity in the relation between COVID-19 perceived stress and depression, anxiety, and panic severity.

The COVID-19 pandemic has had an adverse effect on anxiety and depression symptoms and disorders in the United States and worldwide. As such, there is considerable interest in better understanding the relationship between COVID-19 and anxiety and depressive disorders. Although individual differences in perceived stress have shown to be related to anxiety and depression in non-COVID-19 work, research has not examined potential factors underlying this relation in the context of COVID-19. Fatigue severity may be a promising mechanistic construct for perceived stress and anxiety and depression relations, as some work has found that perceived stress may predict elevated fatigue symptoms. As such, the current study sought to examine the potential explanatory role of fatigue severity in the relation between COVID-19 specific perceived stress and depression, anxiety, and panic symptoms among 563 adults (41.9% female, Mage = 38.26 years, SD = 12.15). Results suggested that COVID-19 perceived stress, via fatigue severity, significantly predicted depression, anxiety, and panic symptoms. These results provide initial empirical support for the role of fatigue severity in the relation between COVID-19 perceived stress and depression, anxiety, and panic symptoms. Future work would benefit from using longitudinal data to evaluate the current model.

Computer-delivered intervention for individuals with obesity and elevated anxiety sensitivity: feasibility, acceptability, and initial test.

Obesity is one the fastest growing public health problems related to numerous chronic diseases and frequently co-occurs with negative mood states. One promising approach to address the heterogeneity of affective vulnerabilities and obesity is to focus on processes (e.g. anxiety sensitivity [AS]) that underpin both conditions. Thus, this study aimed to evaluate the feasibility, acceptability, and initial efficacy of a brief, computer-delivered AS reduction program (AST) for adults with obesity and elevated AS. Participants were 131 individuals with obesity and elevated AS who received either AST or a health information control (HC). Latent growth curve modeling was utilized to examine the effect of treatment condition on change in AS, emotional eating, expectancies of eating to manage mood, and exercise self-efficacy from baseline to 1-week, 2-weeks, and 1-month follow-up. Results indicated it was feasible to recruit and retain individuals with obesity and elevated AS through the 1-month follow-up. Positive qualitative feedback was also provided for both AST and HC. AST was a statistically significant predictor of change in expectancies of eating to manage negative affect. No other statistically significant treatment effects were indicated. Current data provide initial empirical support for future work focused on persons with obesity and elevated AS.

A Pilot Study of the Efficacy of the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Treating Posttraumatic Psychopathology: A Randomized Controlled Trial.

The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) is an intervention that targets common mechanisms that maintain symptoms across multiple disorders. The UP has been shown to be effective across many disorders, including generalized anxiety disorder, major depressive episode (MDE), and panic disorder, that commonly codevelop following trauma exposure. The present study represented the first randomized controlled trial of the UP in the treatment of trauma-related psychopathology, including posttraumatic stress disorder (PTSD), depression, and anxiety symptoms. Adults (N = 43) who developed posttraumatic psychopathology that included PTSD, MDE, or an anxiety disorder after sustaining a severe injury were randomly assigned to receive 10-14 weekly, 60-min sessions of UP (n = 22) or usual care (n = 21). The primary treatment outcome was PTSD symptom severity, with secondary outcomes of depression and anxiety symptom severity and loss of diagnosis for any trauma-related psychiatric disorder. Assessments were conducted at intake, posttreatment, and 6-month follow-up. Posttreatment, participants who received the UP showed significantly larger reductions in PTSD, Hedges' g = 1.27; anxiety, Hedges' g = 1.20; and depression symptom severity, Hedges' g = 1.40, compared to those receiving usual care. These treatment effects were maintained at 6-month follow-up for PTSD, anxiety, and depressive symptom severity. Statistically significant posttreatment loss of PTSD, MDE, and agoraphobia diagnoses was observed for participants who received the UP but not usual care. This study provides preliminary evidence that the UP may be an effective non-trauma-focused treatment for PTSD and other trauma-related psychopathology.

Personalized Feedback for Smoking and Anxiety Sensitivity: A Randomized Controlled Trial.

BACKGROUND: Cigarette smoking is the leading preventable cause of death and disability globally. Most smokers want to quit, and most make a serious quit attempt each year. Nevertheless, more than 95% of cessation attempters relapse within six months. Thus, alternative interventions are needed to combat this major public health concern. Objective: The current study was conducted to develop and test a smoking treatment among 95 (63.2% male; Mage = 46.20 years, SD = 10.90) adult daily cigarette smokers that targets a known risk factor for smoking maintenance and relapse: anxiety sensitivity (AS). Methods: The current study employed a randomized controlled trial design to test an integrated, brief, computer-delivered smoking and AS intervention among current, daily smokers. Participants completed four appointments: (a) phone-screener; (b) baseline (pre-intervention assessment, intervention [personalized feedback intervention (PFI) versus smoking information control], and post-intervention assessment); (c) 2-week follow-up; and (d) 4-week follow-up. Results: Participants indicated highly positive evaluations of both the PFI and control intervention. Between the baseline and 2-week follow-up, 44.2% [PFI: 46.9% (n = 23); control: 41.3% (n = 19)] of participants reported a quit attempt. At the 4-week follow-up, 49.5% [PFI: 57.1% (n = 28); control: 41.3% (n = 19)] of participants reported a quit attempt since their previous laboratory session. Conclusion: Within the context of an intervention development approach, the present investigation provides descriptive data on the feasibility, acceptability, and initial efficacy of a single-session, computer-delivered, AS/smoking PFI.

Examining the longitudinal effects and potential mechanisms of hope on COVID-19 stress, anxiety, and well-being.

Hope is a cognitive trait that predicts both resilience to and recovery from anxiety and stress-related disorders. The present study examines the prospective associations of hope with subsequent anxiety, stress, and well-being during the COVID-19 pandemic. Perceived emotional control, a transdiagnostic vulnerability factor, was also examined as a potential mediator of these relationships. American adults (N = 822) were recruited during the COVID-19 pandemic using Amazon mTURK and structural equation modeling was used to examine how trait hope predicted outcomes approximately one month later. Higher hope was associated with greater well-being and perceived emotional control, as well as lower levels of anxiety and COVID-19 perceived stress. Results also indicated an indirect effect of hope with all outcomes via perceived emotional control. These findings suggest that hope may associated with resilience to the chronic stressors associated with the COVID-19 pandemic.

The Potential Unique Impacts of Hope and Resilience on Mental Health and Well-Being in the Wake of Hurricane Harvey.

Natural disasters can lead to mental health problems, such as posttraumatic stress disorder (PTSD). Higher levels of loss and/or disruption and prior trauma exposure constitute risk factors for mental illness, whereas protective factors, including hope and resilience, support positive functioning. The present cross-sectional study used structural equation modeling to examine the relative influence of resilience and hope on mental health and well-being 1-3 months after Hurricane Harvey made landfall in August 2017, among a sample of 829 adults in the Greater Houston, Texas area. Resilience was more strongly associated with reduced PTSD symptoms, ß = -.31, 95% CI [-.42, -.21], than was hope, ß = -.17, 95% CI [-;.30, -.04], whereas hope was more strongly associated with components of well-being, ßs = .47-.63. Hope was positively associated with posttraumatic growth, ß = .30, 95% CI [.19, .41], whereas resilience was negatively associated with posttraumatic growth, ß = -.24, 95% CI [-.35, -.12]. These associations remained consistent after considering risk factors, although more variance in trauma-related outcomes was risk factors were included in the model. The present results suggest that considering the influence of both risk and resilience factors provides an enhanced picture of postdisaster mental health.

Hope, optimism, self-efficacy, and posttraumatic stress disorder: A meta-analytic review of the protective effects of positive expectancies.

OBJECTIVE: The present meta-analysis consolidated research examining how positive expectancies (e.g., hope, self-efficacy, and optimism) may protect against the development of posttraumatic stress disorder (PTSD). METHOD: Articles were identified by searching PILOTS, PsycINFO, PubMed, and ProQuest Dissertations and Theses databases. RESULTS: Aggregated results from 154 studies indicated that positive expectancies were associated with lower levels of PTSD symptoms. This relationship was stronger for coping-specific self-efficacy (k = 38, r = -.49; -.54 to -.43) and hope (k = 20, r = -.34; -.39 to -.28) compared with general self-efficacy (k = 45, r = -.25; -.30 to -.20) and optimism (k = 59, r = -.29; -.33 to -.25) when examining cross-sectional studies, and results were consistent in prospective studies. Age and gender did not moderate the cross-sectional relationships. CONCLUSIONS: These findings indicate that positive expectancies predict post-trauma resilience. Future research should identify moderators and examine positive expectancies as mechanisms of change in therapy.

Military Veteran Status and Posttraumatic Stress Disorder Symptomatology Among Urban Firefighters: The Moderating Role of Emotion Regulation Difficulties.

A significant portion of firefighters are military veterans, and both populations experience high rates of trauma and posttraumatic stress disorder (PTSD) symptomatology. We investigated main and interactive effects of military veteran status (MVS) and emotion regulation difficulties (ERD) with regard to PTSD symptom severity in firefighters. Covariates included trauma load, number of years in the fire department, and depressive symptom severity. The sample was composed of 839 (93.9% men; mean age = 38.4, SD = 8.5) trauma-exposed firefighters who completed a web-based questionnaire battery. Structural equation modeling was used. ERD were significantly, positively associated with PTSD symptom severity (ß = 0.30, confidence interval [CI] = 0.20-0.41, p < 0.001). A significant interactive effect was noted (ß = 0.07, CI = 0.01-0.14, p = 0.020); firefighters who endorsed MVS and greater ERD had the highest levels of PTSD symptom severity. It is vital that future work examine associations between MVS and relevant cognitive mechanisms for the purposes of informing effective screening, intervention, and prevention programs.

Examining the indirect effect of posttraumatic stress symptoms via emotion dysregulation on alcohol misuse among trauma-exposed Latinx in primary care.

OBJECTIVES: Latinx individuals face substantial health disparities, particularly in the areas of mental health and substance use. Among Latinx in the U.S., alcohol is the most widely abused substance and is associated with a range of negative consequences. Among Latinx, limited past work has linked trauma exposure/symptoms to alcohol misuse, however not much is known regarding how trauma exposure/symptoms may impact alcohol misuse. One potential explanatory mechanism underlying associations of traumatic stress and problematic alcohol use is emotion dysregulation. The current study sought to examine the explanatory role of emotion dysregulation in the associations of traumatic stress symptoms with alcohol misuse among trauma-exposed Latinx. Alcohol misuse was operationalized by two outcomes: alcohol use severity and probable screen for hazardous drinking. METHOD: Latinx adults (N = 238) were recruited from a Federally Qualified Health Center. Participants were interviewed using the M.I.N.I. and then completed various self-report assessments (in Spanish). Structural equation modeling was used to evaluate models. RESULTS: Structural models fit the data well. These models evidenced statistically significant indirect effects of posttraumatic stress symptoms via emotion dysregulation on alcohol use severity and probable screen for hazardous drinking. DISCUSSION AND CONCLUSIONS: In a sample comprising primarily females, posttraumatic stress symptoms may contribute to alcohol misuse and hazardous drinking attributable to maladaptive emotion regulation. Use of interventions targeting emotion dysregulation in the context of trauma and hazardous alcohol use among Latinx in primary care may be warranted.

Expressive Writing Intervention Improves Quality of Life Among Chinese-American Breast Cancer Survivors: A Randomized Controlled Trial.

Background: Expressive writing interventions are shown to confer health benefits for Caucasian cancer survivors. However, few studies reported improved quality of life or studied ethnic minorities. Purpose: The study evaluated whether a culturally sensitive expressive writing intervention improved quality of life. Methods: Chinese-speaking breast cancer survivors (n = 136) in the USA were randomly assigned to one of three conditions to write three 30-min weekly essays: a cancer-fact condition to write about facts relevant to the cancer experience for three weeks; a self-regulation condition to write about deepest feelings at week 1, stress and coping at week 2, and finding benefits at week 3; or an enhanced self-regulation condition to write about stress and coping at week 1, deepest feelings at week 2, and finding benefits at week 3. Quality of life was assessed by Functional Assessment of Cancer Therapy at baseline, 1-, 3-, and 6-month follow-ups. Results: Growth curve models showed that quality of life was increased in the sample from baseline to the 6-month follow-up. The enhanced self-regulation condition had a large and statistically significant effect (d = 0.90, 95% CI [0.02, 1.687]), and the self-regulation condition had a small effect (d = 0.22, 95% CI [-0.79, 1.07]) on quality of life improvement compared with the cancer-fact group. Conclusion: Expressive writing is shown to be an effective intervention to improve quality of life for Chinese-American cancer survivors. Future efforts are warranted to disseminate and implement this low-dose and brief intervention in community and clinical settings. Clinical Trial Registration: NCT02946619.

Psychological Distress Among Smokers in the United States: 2008-2014.

Introduction: Decline in smoking in the United States has slowed over the past 25 years. Mental health problems are common among smokers, and may be an impediment to quitting and remaining abstinent. The study investigated the relationship between serious (past-30-day) psychological distress (SPD) and smoking, estimated trends in the prevalence of SPD among current, former, and never smokers in the United States from 2008 to 2014, and investigated whether heterogeneity in these trends varied by sociodemographic characteristics. Methods: Data were drawn from the National Household Survey on Drug Use (NSDUH), an annual cross-sectional study of persons ages 12 and over (N = 270 227). SPD and smoking in the past 30 days were examined using logistic regression models among adults 18 and older. The prevalence of SPD was examined annually among current, former, and never smokers from 2008 to 2014. Results: SPD increased among smokers in the United States from 2008 to 2014. An increase in SPD was more rapid among non-daily smokers than daily smokers. The prevalence of SPD was higher among younger smokers, those with less formal education and lower annual family income and higher among current smokers than former and never smokers. The relationships between SPD and smoking were stronger among smokers with higher education levels and annual family income. Conclusions: Our findings suggest an increase in SPD among smokers over time and that as smoking has declined, those with SPD are comprising a greater proportion of the remaining smokers. Results suggest that mental health must be integrated into mainstream tobacco control efforts. Implications: The greater prevalence and increasing rate of Serious Psychological Distress among smokers, relative to former- and never-smokers, from 2008 to 2014 provides support that the greater mental health burden among smokers may be contributing to the slowed reduction in smoking prevalence in the United States. In addition, relationships between SPD and smoking were consistently stronger among smokers with higher levels of education and annual family income. Such results suggest the necessity of incorporating mental health treatments in tobacco use reduction efforts.

Posttraumatic stress, alcohol use, and alcohol use reasons in firefighters: The role of sleep disturbance.

BACKGROUND: Firefighters are at elevated risk for posttraumatic stress and alcohol use, with research indicating that individuals with posttraumatic stress are likely to use alcohol as a coping strategy. A behavioral mechanism of clinical relevance to these associations is sleep disturbance. Thus, it was hypothesized that higher posttraumatic stress and sleep disturbance would be associated with higher alcohol use and alcohol use coping reasons; and sleep disturbance would moderate the association between posttraumatic stress and alcohol use and alcohol use coping reasons. PROCEDURE: Participants included 639 urban career firefighters (93.6% male; 77.9% White; Mage = 38.5). Covariates included fire department years and occupational stress. Structural equation models were tested. RESULTS: Posttraumatic stress severity was significantly, positively associated with alcohol use severity and alcohol use coping reasons. Similarly, sleep disturbance severity was significantly, positively associated with alcohol use severity and alcohol use coping reasons. After accounting for covariates and main effects, the interaction of PTSD severity and sleep disturbance was significantly associated with alcohol use severity, with the model accounting for 23.6% of variance, and alcohol use coping reasons, with the model accounting for 37.6% of variance. As predicted, the interaction of posttraumatic stress severity and sleep disturbance was not significantly associated with alcohol use enhancement, conformity, or social reasons. CONCLUSION: These findings indicate that posttraumatic stress severity is related to heightened alcohol use severity and alcohol use coping reasons, and this association is markedly stronger when firefighters' levels of sleep disturbance are heightened. Clinical and research implications are to be discussed.

The unique and interactive effects of anxiety sensitivity and emotion dysregulation in relation to posttraumatic stress, depressive, and anxiety symptoms among trauma-exposed firefighters.

BACKGROUND: Firefighters are chronically exposed to traumatic events. Relatedly, past work has documented high rates of psychiatric problems, such as posttraumatic stress symptoms and depression, among firefighters. Less is known regarding anxiety symptoms among firefighters. Moreover, little work has examined risk/maintenance factors related to these symptoms among firefighters. Doing so may be important to developing interventions tailored to trauma-exposed firefighters. The current study examined symptoms of posttraumatic stress, depression, panic disorder, and social anxiety among trauma-exposed firefighters. PROCEDURE: Using structural equation modeling, the main and interactive effects of anxiety sensitivity and emotion dysregulation were examined in relation to these symptom outcomes. Participants included 787 male urban firefighters reporting at least one past traumatic event. RESULTS: There was a statistically significant main effect of anxiety sensitivity on each outcome. Emotion dysregulation exerted a statistically significant main effect on posttraumatic stress, depression, and social anxiety symptoms. Interactive effects of anxiety sensitivity and emotion dysregulation did not reach statistical significance but examination of effect sizes suggests that interactive effects may be present for posttraumatic stress symptoms (R2 = 0.011), depression (R2 = 0.008), and panic (R2 = 0.016) such that emotion dysregulation is more strongly related to outcomes when anxiety sensitivity levels are relatively lower. All effects were evident after controlling for trauma severity and history of armed forces service. CONCLUSION: Overall, results suggest that anxiety sensitivity and emotion dysregulation represent unique risk/maintenance factors related to a broad range of emotional symptoms among trauma-exposed firefighters. These findings replicate patterns found among the general population and extend the findings to potentially vulnerable firefighters.
