Introduction Traumatic event exposure is common among cigarette smokers, and elevated posttraumatic stress symptoms (PTSS) are associated with increased smoking levels. As such, the current study examined factors that may contribute to elevated PTSS among trauma-exposed smokers. Insomnia and emotion dysregulation may be particularly relevant among...

Panic attacks (PAs) defined as a discrete period of intense fear or discomfort, occur in the context of numerous anxiety and mood related disorders. Research has suggested that PAs serve as a significant indicator and prognostic factor for overall symptom severity, course, and comorbidity within various conditions. Consequently, a PA specifier is n...

Although Al-Anon Family Groups (Al-Anon) is the most common source of help for people concerned about someone else's drinking, only 16% of members are men. To identify gender differences, we compared demographics, reasons for attendance, health status, and personal functioning, and drinker characteristics of 174 men and women attending Al-Anon. Men...

The present study is the first to explore links between PTSD and cannabis use characteristics immediately prior to a cannabis quit attempt, including motives, use problems, withdrawal, and craving. Measures of PTSD diagnosis, symptom severity, and cannabis use characteristics were administered to a sample of cannabis dependent military veterans (n...

Objectives The Emotional Cascade Model posits that rumination is associated with impulsivity and risky behaviours such as substance use. Although trauma‐exposed individuals often engage in rumination and problematic cannabis use, this model has not been tested on trauma‐exposed cannabis users. Therefore, our study examines the direct and indirect e...

Introduction Previous research has identified a variety of barriers to mental health care among military personnel and veterans, despite high rates of mental health symptoms. The current study is the first to examine beliefs about mental health treatment barriers among post‐9/11 military personnel and veterans at elevated suicide risk not involved...

Prior research has linked chronic pain with posttraumatic stress disorder (PTSD) symptoms, but findings regarding the association between pain and substance use disorder (SUD) severity have been mixed. One explanation for the discrepant findings may be based on the ways in which SUD outcomes are measured. That is, it may be that pain has a differen...

Anxiety sensitivity (AS), defined as the fear of anxious arousal, is a promising therapeutic target to reduce posttraumatic stress disorder (PTSD) symptom development after trauma exposure. Computerized AS interventions have been shown to be acceptable to individuals with PTSD symptoms and effective in achieving symptom reduction; however, to our k...

Despite their brevity, prior work indicates that computer-based interventions can substantially impact risk factors for psychopathology including anxiety sensitivity (AS), thwarted belongingness (TB), and perceived burdensomeness (PB). However, very few studies have assessed the long-term (> 1 year) effects of these interventions. The primary aim o...

Anxiety sensitivity, or fear of anxious arousal, is cross-sectionally associated with a wide array of adverse posttraumatic neuropsychiatric sequelae, including symptoms of posttraumatic stress disorder, depression, anxiety, sleep disturbance, pain, and somatization. The current study utilizes a large-scale, multi-site, prospective study of trauma...

Objective: Chronic pain and posttraumatic stress disorder (PTSD) are two highly prevaxlent and comorbid conditions common within veteran populations. Notably, those with comorbid pain and PTSD tend to have more severe presentations and poorer quality of life than those with either disorder alone. Despite this well-established relationship, limited...

Background and objectives: Anxiety sensitivity, or fear of anxious arousal, may be an important risk factor for problematic cannabis use. Specifically, anxiety sensitivity may motivate cannabis use to cope with distress, particularly among trauma-exposed individuals. The current study tested associations among anxiety sensitivity, its subdomains,...

Sexual violence is associated with increased rates of posttraumatic stress disorder (PTSD) symptoms (PTSS) among survivors. Intolerance of uncertainty (IU), or a fear of the unknown, has been consistently linked with PTSS. However, no research has examined IU and PTSS across different trauma types. The current study examined whether differences exi...

Insomnia symptoms are common among individuals with psychiatric disorders, and associated with increased symptom severity. However, the Insomnia Severity Index (ISI) has rarely been psychometrically evaluated in a psychiatric sample. Furthermore, the latent structure of the ISI has not been evaluated using factor mixture modeling, which improves up...

Background Insomnia symptoms may be an important etiological factor for substance use disorders; however, whether improving sleep leads to reductions in problematic substance use among at-risk populations remains unclear. Method As such, the current pilot study used a randomized controlled design to test the effects of Brief Behavioral Treatment f...

Intolerance of uncertainty (IU) is an important transdiagnostic risk factor across internalizing conditions. Little research has focused on establishing temporal relationships between IU and these conditions. The current study examined whether changes in IU across one year would lead to increased internalizing symptoms and elevations across diagnos...

Posttraumatic stress disorder (PTSD) has empirically-established associations with positive emotion dysregulation. Extending existing research, we utilized a network approach to examine relations between PTSD symptom clusters (intrusions, avoidance, negative alterations in cognitions and mood [NACM], alterations in arousal and reactivity [AAR]) and...

Background Recent research has linked emotion dysregulation with increases in subjective ratings of negative affect (NA reactivity) to trauma reminders, a central symptom of posttraumatic stress disorder (PTSD). The current study adds to this burgeoning line of research by exploring elicited PTSD symptoms as a mechanism explicating the relation bet...

Objective: Posttraumatic stress disorder (PTSD) is a prevalent and impairing condition that often involves difficulties with interpersonal functioning. Targeting interpersonal difficulties may be a promising alternative approach to reducing PTSD symptoms, particularly given the relatively low rates of treatment engagement and efficacy for first-li...

Insomnia symptoms prior to traumatic event exposure predict the development of post‐traumatic stress symptoms. However, potential mechanisms underlying the association between insomnia and risk for post‐traumatic stress disorder symptoms have not been prospectively tested. The current study used the trauma film paradigm to test whether insomnia sym...

Anxiety and insomnia disorders are two of the most common and costly mental health conditions. They are frequently comorbid, but current treatments do not target both. To streamline treatment, we developed a computerized intervention targeting a transdiagnostic factor, safety aids (cognitive or behavioral strategies used to cope with distress that...

Objective: The current study tested whether emotion dysregulation predicts suicidal ideation over the course of six months. Methods: Community members (N = 298) with elevated suicide risk completed a clinical interview and self-report questionnaires at baseline and month-six follow-up appointments. Results: Elevated general emotion dysregulation an...

Background: Despite evidence that insomnia symptoms exacerbate alcohol use disorder symptoms, there is a dearth of prospective research testing bidirectional associations between these variables. Furthermore, no studies have prospectively examined these associations among military personnel, a vulnerable population for sleep- and alcohol-related p...

Low distress tolerance, the perceived or actual inability to tolerate negative emotional states, is a transdiagnostic risk marker associated with greater PTSD symptoms and poorer treatment outcomes. However, the role of distress tolerance in PTSD symptom trajectories has not yet been explored. This study examined the mediating role of distress tole...

Objective: High anxiety sensitivity (AS) and poor attention control (AC) are established risk factors for posttraumatic stress symptoms (PTSS), but little is known about the combined influence of these variables. Consistent with dual-systems models suggesting facets of executive function (e.g., AC) will modulate the effects of other risk factors (...

Rates of suicide and major depressive disorder (MDD) are currently at the highest point in the history of the United States (US). However, these rates are not distributed evenly among the population and Latinos show disproportionately high rates of both suicide and MDD. Yet, past research has infrequently explored factors related to suicide and MDD...

Background Although a burgeoning line of research identifies emotion regulation difficulties as a potential maintenance factor for posttraumatic stress disorder (PTSD), little is known in regard to what emotion regulation strategies individuals with PTSD use in their daily lives, their predictors, and their consequences on later PTSD symptoms. Meth...

Objective: We examined associations between sleep problems, distress intolerance, and perceived stress and health in a convenience sample of homeless adults. Methods: Participants (N = 513, 36% women, Mage = 44.5 ±11.9) self-reported sleep adequacy, sleep duration, unintentional sleep during the daytime, distress tolerance, urban stress, and day...

A growing number of studies identify insomnia symptoms as a potential risk factor for the development of anxiety disorders. However, little research has examined potential mechanisms through which insomnia could confer increased risk for anxiety. A separate line of literature suggests sleep is necessary for adaptive emotional and behavior respondin...

Insomnia disorder is impairing and prevalent, particularly among individuals with comorbid anxiety disorders. Despite the availability of effective computerized treatments for insomnia, there are few that target both insomnia as well as co-occurring anxiety symptoms. The current study tests the efficacy of a computerized treatment for anxiety sensi...

Despite the high levels of comorbidity between post-traumatic stress disorder (PTSD) and sleep disturbance, little research has examined the predictors of insomnia and nightmares in this population. The current study tested both PTSD-specific (i.e. PTSD symptoms, comorbid anxiety and depression, nightmares and fear of sleep) and insomnia-specific (...

Within a hierarchical framework for depressive and anxiety disorders, negative affect (NA) is posited to be indirectly related to social anxiety and depression through cognitive vulnerabilities, including intolerance of uncertainty (IU) and anxiety sensitivity (AS). However, few prior studies have considered whether the lower-order dimensions of IU...

Recent research has highlighted the etiological role of sleep disturbance in posttraumatic stress disorder (PTSD); however it is currently unknown how daily changes in sleep are associated with next-day PTSD symptoms. Furthermore, sleep is critical for maintaining appropriate affect, leading some to hypothesize that affective dysfunction may accoun...

Background: Despite recent research establishing high rates of comorbidity between hoarding disorder and alcohol use disorders (AUD), no studies have systemically examined the associations between symptoms of hoarding and alcohol use. Moreover, no studies have explored potential mechanisms that may help to explain these relations. Objectives: Th...

A growing body of research suggests the importance of anxiety sensitivity (AS) in the development and maintenance of posttraumatic stress symptoms (PTSS). Specifically, AS cognitive concerns (fears of cognitive dyscontrol) may be particularly relevant for those with elevated PTSS. Preliminary research has suggested that interventions targeting AS m...

Introduction: Nonsuicidal self-injury (NSSI) is a transdiagnostic behavior associated with significant psychopathology. Research has shown a positive association between sleep disturbances, (e.g., nightmares and insomnia), and suicidal behavior, however, the relation between NSSI and sleep disturbances has yet to be examined. Sleep disturbances ha...

Prior research has shown that difficulties in emotion regulation is associated with overall levels of posttraumatic stress symptoms (PTSS). However, it is currently unclear which facets of difficulties in emotion regulation (e.g., lack of emotion regulation strategies, impulse control problems, non-acceptance of emotional responses) are associated...

Despite the well-documented efficacy of cognitive behavioral treatments for anxiety disorders, the acceptability of these treatments remains an under-researched area. A better understanding of acceptability could help to improve the initiation of, and engagement in, these effective interventions. Recent research has suggested computerized intervent...

Background: Hoarding disorder (HD) is a common and debilitating disorder characterized by an accumulation of and failure to discard one's possessions. The identification and examination of underlying factors that may contribute to hoarding symptoms are needed to elucidate the nature of the disorder and refine existing treatments. Two transdiagnost...

Background: Intolerance of uncertainty (IU) has been associated with post-traumatic stress symptoms (PTSS) in the literature. However, no research to date has investigated the relationship between IU and PTSS within a clinical trauma-exposed sample, which is an important next step in the literature and crucial for the generalizability of these fin...

Despite clear indications that hoarding behaviors contribute to social isolation and strained family relationships, no research to date has examined the associations between hoarding and several important interpersonal constructs (i.e., perceived burdensomeness and thwarted belongingness). Moreover, no research has examined how these various interp...

Intolerance of uncertainty (IU) is a multidimensional construct that has been proposed as an important transdiagnostic risk factor across various anxiety and mood disorders. Recent work found support for IU having a continuous latent structure when utilizing taxometric methods. However, taxometrics may not be ideally suited to examine the latent st...

Insomnia symptoms are associated with smoking and may interfere with smoking cessation. Specifically, studies have shown that smoking-related sleep problems are associated with long-term smoking relapse, and longer sleep duration is associated with successful smoking cessation. However, it is currently unclear whether pre- or post-quit insomnia sym...

Objective: Whereas a triple vulnerability model has been used to evaluate several anxiety- and mood-related conditions, no research has purposefully examined hoarding from this perspective. Method: Using a multivariate approach, the current study evaluated the unique relations between hoarding and a general biological (e.g., neuroticism), psycho...

Anxiety sensitivity (AS), the feared consequences of anxious arousal, is known to be related to posttraumatic stress symptoms (PTSS) concurrently and longitudinally. However, no studies have demonstrated whether AS prior to a Criterion A traumatic event predict later PTSS. The present study evaluated whether pre-shooting AS predicted PTSS following...

Despite well-established gender differences in the rates of Posttraumatic Stress Disorder (PTSD), there is a lack of research examining malleable, gender-linked risk factors that could be targeted in interventions to reduce risk among women. One such risk factor is anxiety sensitivity (AS), or a fear of anxiety related sensations. AS is elevated in...

Poor sleep quality is common among veterans, and associated with numerous negative consequences. Although sleep may play a critical role in next-day emotion regulation functioning, it is currently unclear how sleep quality relates to distress tolerance. As such, the current study cross-sectionally examined the association between sleep quality and...

Intolerance of uncertainty (IU) has been associated with elevated post-traumatic stress symptoms (PTSS) in the extant literature. However, no research to date has investigated whether pre-trauma IU predicts PTSS following trauma exposure. The current study prospectively examined the relationship between IU and PTSS within a sample of individuals wi...

Panic attacks (PAs) are characterized by overwhelming surges of fear and discomfort and are one of the most frequently occurring symptoms in psychiatric populations. The most recent version of the Diagnostic and Statistical Manual of Mental Disorders (i.e. DSM-5) allows for a panic attack (PA) specifier for all disorders, including social anxiety d...

In light of recent data demonstrating large variability in the diagnosis of cannabis use disorders (CUDs) within the Veterans Affairs Health Care System (VA), it is important to elucidate VA-specific barriers and facilitators to CUD diagnosis and treatment engagement. This issue is particularly salient among veterans with posttraumatic stress disor...

Anxiety sensitivity (AS), or fear of anxious arousal, is a higher-order cognitive risk-factor for posttraumatic stress disorder (PTSD) composed of lower-order physical, cognitive, and social concerns regarding anxiety symptoms. Brief and effective interventions have been developed targeting AS and its constituent components. However, there is limit...

Although posttraumatic stress disorder (PTSD) is associated with self-injurious behavior, it is currently unclear what mechanisms may account for this relationship. Sleep disturbances may be relevant as they are common among those with PTSD and are associated with emotion regulation difficulties, which may increase vulnerability to self-injurious b...

Whereas prior work has established fear and distress clusters underlying unipolar mood and anxiety disorders, the optimal placement of obsessive-compulsive disorder (OCD) within this model is unclear. One likely contributor to this ambiguity is the heterogeneous nature of OCD. There is increasing evidence for distinct symptom dimensions that are mo...

Existing research on the relationship between obsessive-compulsive disorder (OCD) and insomnia is scarce. Moreover, no research has examined potential mechanisms that may account for the observed relations among OCD and sleep difficulties. The cognitive concerns subscale of anxiety sensitivity (AS), which reflects fears of mental incapacitation, ha...

Rumination, defined as an individual's repetitive negative cognitions of upsetting symptoms in response to distress, has been established as an important cognitive vulnerability factor within various forms of psychopathology. Despite compelling data to suggest that rumination is associated with a number of mood and anxiety-related conditions, no re...

Whereas it has been suggested that hoarding is a multidimensional construct comprising distinct but interrelated factors (i.e., difficulty discarding, excessive clutter, and excessive acquisition), a high degree of overlap as well as a lack of discriminant validity among these factors and exogenous constructs suggests that a correlated factors appr...

This study aimed to investigate the interactive influence of problematic cannabis use on the relation between sleep quality and posttraumatic stress symptoms (PTSS). Hypotheses were tested cross-sectionally among 151 medical cannabis users with PTSS. Consistent with hypotheses, we found sleep quality to be associated with PTSS severity. In addition...

Many cigarette smokers have experienced a traumatic event, and elevated posttraumatic stress symptoms (PTSS) are associated with increased smoking levels. Previous research has found that elevated PTSS are associated with smoking to cope with negative affect, and it has been posited that perceptions of being unable to cope with the consequences of...

Anxiety sensitivity (AS), has been conceptualized as a hierarchical construct, comprising three lower-order dimensions. Recent findings suggest that AS may be better conceptualized as a general dimension and unrelated physical, cognitive, and social concerns dimensions (a bifactor model). The current study was designed to examine whether a bifactor...

Insomnia has been shown to have profound negative consequences on multiple aspects of daily functioning. Despite increased interest in the association between insomnia and psychopathology, no research has examined the relationships between insomnia and hoarding. The aim of the current investigation was to examine the associations between insomnia a...

Recent work suggests a link between a transdiagnostic vulnerability factor, anxiety sensitivity (AS), and sleep disturbance. Although research has indicated that AS is malleable through brief interventions, no studies have yet examined whether interventions targeting AS will reduce symptoms of insomnia. Considering this gap in previous research, th...

Hoarding disorder is characterized by persistent difficulty discarding possessions resulting in clutter that precludes one from using living areas for their intended purposes. The limited empirical work available has suggested a strong link between hoarding and various non-psychiatric conditions, including obesity. Despite these associations, no re...
