Basic emotion profiles in healthy, chronic pain, depressed and PTSD individuals

Trauma reminders and disgust: The roles of posttraumatic stress disorder symptom severity, trauma type, and reminder type

Disgust is a common emotional response to trauma but is studied less frequently than fear or other negative emotions. In laboratory settings, individuals with a history of sexual assault report more disgust following exposure to trauma reminders than those exposed to other trauma types, and people with more severe posttraumatic stress disorder (PTSD) symptoms typically report more disgust than those with lower symptom levels. It remains unknown whether this association is also present in ecological contexts and if these associations vary by trauma reminder type. The present sample included 80 trauma-exposed community members (PTSD: n = 39, no PTSD: n = 41) who completed up to 17 prompts per day for 3 days (2,158 total completed surveys). Multilevel models indicated that trauma reminders were associated with increased feelings of disgust, B = 0.16, SE = 0.06, p < .001, which was consistent across trauma reminder types, p < .001-p = .001. PTSD symptom severity moderated the association between trauma reminders and disgust such that it was stronger for participants with higher CAPS-5 scores, B = 0.02, SE = 0.01, p = .011. All trauma reminder types demonstrated the same pattern of moderation, ps = .003-.022, except flashbacks, p = .070. Trauma type was not a significant moderator of any trauma reminder type, ps = .193-.929. These findings suggest that trauma reminders encountered in daily life are associated with feelings of disgust. The results underscore the importance of exploring disgust as a trauma-related emotional experience among trauma survivors.

An Emotion-Driven Vocal Biomarker-Based PTSD Screening Tool

Goal: This paper introduces an automated post-traumatic stress disorder (PTSD) screening tool that could potentially be used as a self-assessment or inserted into routine medical visits to aid in PTSD diagnosis and treatment. Methods: With an emotion estimation algorithm providing arousal (excited to calm) and valence (pleasure to displeasure) levels through discourse, we select regions of the acoustic signal that are most salient for PTSD detection. Our algorithm was tested on a subset of data from the DVBIC-TBICoE TBI Study, which contains PTSD Check List Civilian (PCL-C) assessment scores. Results: Speech from low-arousal and positive-valence regions provide the highest discrimination for PTSD. Our model achieved an AUC (area under the curve) of 0.80 in detecting PCL-C ratings, outperforming models with no emotion filtering (AUC = 0.68). Conclusions: This result suggests that emotion drives the selection of the most salient temporal regions of an audio recording for PTSD detection.

Distinguishing emotional numbing symptoms of posttraumatic stress disorder from major depressive disorder

Emotional numbing symptoms are a core aspect of posttraumatic stress disorder (PTSD). Since the initial characterization of PTSD in DSM-III, emotional numbing symptoms have been revised and grouped under different symptom clusters (avoidance in DSM-IV, negative alterations in cognitions, and mood in DSM-5). Previous studies have found emotional numbing symptoms to be associated with greater PTSD severity, functional impairment, and worse treatment outcomes. Although considered an important feature, some argue that emotional numbing symptoms may simply reflect the manifestation of major depressive disorder (MDD) symptoms rather than be an inherent part of the PTSD phenotype. Here, we evaluated this question using two different data sets (N1 = 142; CAPS-5, N2 = 163; CAPS-4) of trauma-exposed individuals. First, we evaluated the unique variance of emotional numbing explained by diagnosis as binary variables (i.e., having PTSD, MDD, or both) and the severity of symptoms. Second, we examined the relative importance of each PTSD symptom in relation to emotional numbing symptoms. Results revealed that PTSD had a distinct contribution to the variance explaining emotional numbing symptoms above and beyond MDD. These findings suggest that emotional numbing should not be conceptualized as a simple manifestation of MDD symptoms. Rather, this symptom cluster may be a unique feature of PTSD that should be addressed within the context of trauma.

Parenting behaviors of mothers with posttraumatic stress: The roles of cortisol reactivity and negative emotion

Although posttraumatic stress disorder (PTSD) is associated with negative family outcomes, including parenting challenges, little is known about the biological and emotional processes that might underlie this association. The present project addressed this gap by examining associations between maternal PTSD and parenting behaviors in a lab setting. We expected that PTSD would be associated with more ineffective parenting behaviors and that negative emotion and cortisol reactivity would mediate this relation. A total of 78 mothers and their toddler-aged children completed a task designed to elicit parental responses to typical instances of child misbehavior. Salivary cortisol was collected from mothers prior and subsequent to the lab paradigm and mothers provided ratings of their experienced emotion while viewing a video of the interaction. Contrary to hypotheses, cortisol reactivity did not mediate associations between PTSD and parenting. However, findings suggest that PTSD is associated with greater permissive parenting behaviors, and mothers with even subthreshold symptoms of PTSD may experience more negative emotion during challenging parent-child interactions that ultimately interferes with parenting. Mothers with PTSD may benefit from interventions that focus on modifying the intensity of their negative emotions in the context of child misbehavior to more effectively set limits in everyday discipline encounters.

The N400 and late occipital positivity in processing dynamic facial expressions with natural emotional voice

People require multimodal emotional interactions to live in a social environment. Several studies using dynamic facial expressions and emotional voices have reported that multimodal emotional incongruency evokes an early sensory component of event-related potentials (ERPs), while others have found a late cognitive component. The integration mechanism of two different results remains unclear. We speculate that it is semantic analysis in a multimodal integration framework that evokes the late ERP component. An electrophysiological experiment was conducted using emotionally congruent or incongruent dynamic faces and natural voices to promote semantic analysis. To investigate the top-down modulation of the ERP component, attention was manipulated via two tasks that directed participants to attend to facial versus vocal expressions. Our results revealed interactions between facial and vocal emotional expressions, manifested as modulations of the auditory N400 ERP amplitudes but not N1 and P2 amplitudes, for incongruent emotional face-voice combinations only in the face-attentive task. A late occipital positive potential amplitude emerged only during the voice-attentive task. Overall, these findings support the idea that semantic analysis is a key factor in evoking the late cognitive component. The task effect for these ERPs suggests that top-down attention alters not only the amplitude of ERP but also the ERP component per se. Our results implicate a principle of emotional face-voice processing in the brain that may underlie complex audiovisual interactions in everyday communication.

The Reward System and Post-Traumatic Stress Disorder: Does Trauma Affect the Way We Interact With Positive Stimuli?

Post-traumatic stress disorder (PTSD) is a highly prevalent disorder and a highly debilitating condition. Although anhedonia is an important construct of the disorder, the relationship between PTSD and reward functioning is still under-researched. To date, the majority of research on PTSD has focused on fear: fear learning, maintenance, and extinction. Here we review the relevant literature-including clinical observations, self-report data, neuroimaging research, and animal studies-in order to examine the potential effects of post-traumatic stress disorder on the reward system. Our current lack of sufficient insight into how trauma affects the reward system is one possible hindrance to clinical progress. The current review highlights the need for further investigation into the complex relationship between exposure to trauma and the reward system to further our understandings of the ethology of PTSD.

Beyond Adaptive Mental Functioning With Pain as the Absence of Psychopathology: Prevalence and Correlates of Flourishing in Two Chronic Pain Samples

Chronic pain outcomes are traditionally defined in terms of disability and illness. A definition of adaptive functioning in the context of chronic pain beyond the mere absence of negative outcomes, is the ability to flourish (i.e., experience emotional, psychological and social well-being; Keyes, 2002). We explored in two chronic pain samples the prevalence and sociodemographic, physical and psychological correlates of flourishing, and complemented this exploration with a similar examination of (being at risk for) psychopathology to help contextualize findings. Sample 1 (n = 1498) was a nationally representative sample. Subgroups included people with regular joint pain (1), regular joint pain and rheumatoid arthritis (2) and without chronic pain (3). Using chi-square tests we calculated the prevalence of both mental health outcomes and examined if people with or without chronic pain were more/less likely to flourish/at risk for psychopathology. Sample 2 (n = 238) concerned baseline data of a Randomized Controlled Trial on the effectiveness of Acceptance and Commitment Therapy for chronic pain (Trompetter et al., 2015b). We performed logistic regression analysis to identify flourishers/those at risk for depression. The Mental Health Continuum-Short Form was used to measure flourishing. The prevalence of flourishing was 34% (recurrent joint pain) and 38% (recurrent joint pain and arthritis) in sample 1, and 23% in sample 2. Compared to those without chronic pain, people with chronic pain were as likely to flourish, but more likely to be at risk for psychopathology. In sample 2, both flourishing and being at risk for depression were related foremost to psychological correlates. While engaged living was the most important correlate of flourishing, pain catastrophizing and psychological inflexibility were most important correlates of being at risk for depression. In conclusion, people with chronic pain are able to flourish. Findings suggest that positive and negative chronic pain outcomes function on two different continua, with potentially unique protective and risk factors. The Psychological Flexibility model provides pathways to explain both poor and optimal functioning in the presence of chronic pain. A better understanding of people with chronic pain who are able to flourish can be a fruitful endeavor to improve chronic pain models and interventions.

Does Working Memory Moderate the Within-Person Associations Between Pain Intensity and Negative Affect and Pain's Interference With Work Goal Pursuit?

OBJECTIVES

Chronic pain exerts a pervasive negative influence on workers' productivity. However, a paucity of research has addressed the mechanisms underlying the pain → productivity relation. In the present study using intensive daily diary data, we examined whether working memory (WM) moderates the positive within-person associations between (1) morning pain intensity and (2) morning negative affect (NA) and later day pain's interference of work-goal (WG) pursuit.

METHODS

A community sample of 131 adults with chronic pain completed a battery of questionnaires, laboratory-measured WM, and a 21-day daily diary.

RESULTS

WM did not moderate the positive within-person association between morning pain intensity and afternoon/evening ratings of pain's interference with work goal pursuit. However, individuals with higher WM showed significantly attenuated positive within-person association between morning negative affect and pain's interference with afternoon/evening work goal pursuit.

DISCUSSION

WM appears to protect goal-relevant information from distractions due to negative affective arousal. The continued use of ecologically valid observational and intervention studies would shed further light on the influence of WM on the pursuit of valued work goals in the face of pain and negative affect.

Diminished positive affect and traumatic stress: A biobehavioral review and commentary on trauma affective neuroscience

Post-traumatic stress manifests in disturbed affect and emotion, including exaggerated severity and frequency of negative valence emotions, e.g., fear, anxiety, anger, shame, and guilt. However, another core feature of common post-trauma psychopathologies, i.e. post-traumatic stress disorder (PTSD) and major depression, is diminished positive affect, or reduced frequency and intensity of positive emotions and affective states such as happiness, joy, love, interest, and desire/capacity for interpersonal affiliation. There remains a stark imbalance in the degree to which the neuroscience of each affective domain has been probed and characterized in PTSD, with our knowledge of post-trauma diminished positive affect remaining comparatively underdeveloped. This remains a prominent barrier to realizing the clinical breakthroughs likely to be afforded by the increasing availability of neuroscience assessment and intervention tools. In this review and commentary, the author summarizes the modest extant neuroimaging literature that has probed diminished positive affect in PTSD using reward processing behavioral paradigms, first briefly reviewing and outlining the neurocircuitry implicated in reward and positive emotion and its interrelationship with negative emotion and negative valence circuitry. Specific research guidelines are then offered to best and most efficiently develop the knowledge base in this area in a way that is clinically translatable and will exert a positive impact on routine clinical care. The author concludes with the prediction that the development of an integrated, bivalent theoretical and predictive model of how trauma impacts affective neurocircuitry to promote post-trauma psychopathology will ultimately lead to breakthroughs in how trauma treatments are conceptualized mechanistically and developed pragmatically.

Chronic Pain Types Differ in Their Reported Prevalence of Post -Traumatic Stress Disorder (PTSD) and There Is Consistent Evidence That Chronic Pain Is Associated with PTSD: An Evidence-Based Structured Systematic Review

Objectives

The hypotheses of this systematic review were the following: 1) Prevalence of post-traumatic stress disorder (PTSD) will differ between various types of chronic pain (CP), and 2) there will be consistent evidence that CP is associated with PTSD.

Methods

Of 477 studies, 40 fulfilled the inclusion/exclusion criteria of this review and were grouped according to the type of CP. The reported prevalence of PTSD for each grouping was determined by aggregating all the patients in all the studies in that group. Additionally all patients in all groupings were combined. Percentage of studies that had found an association between CP and PTSD was determined. The consistency of the evidence represented by the percentage of studies finding an association was rated according to the Agency for Health Care Policy and Research guidelines.

Results

Grouping PTSD prevalence differed ranging from a low of 0.69% for chronic low back pain to a high of 50.1% in veterans. Prevalence in the general population with CP was 9.8%. Of 19 studies, 16 had found an association between CP and PTSD (84.2%) generating an A consistency rating (consistent multiple studies). Three of the groupings had an A or B (generally consistent) rating. The veterans grouping received a C (finding inconsistent) rating.

Conclusion

The results of this systematic review confirmed the hypotheses of this review.

Pain and multiple facets of anger and hostility in a sample seeking treatment for problematic anger

A number of studies have reported associations between pain and anger in samples with chronic pain, but research has mostly overlooked associations between pain and anger in those with problematic anger. The present study explored associations between pain severity and a variety of anger and hostility constructs in a sample seeking anger treatment (n =131). Zero-order correlations and partial correlations were used to examine associations between pain, anger, and hostility, controlling for depressive symptoms. Hierarchical regression models examined potential interaction effects of gender on associations between pain and these outcomes. Pain severity was positively associated with trait anger, outward anger expression, hostile interpretation bias, hostile ideation, and inability to forgive others. These associations were independent of co-occurring depressive symptoms, with some exceptions. Gender moderated the association between pain and hostile ideation such that pain was positively associated with hostile ideation in women but not men. Pain severity was uniquely associated with multiple outcomes of relevance to individuals undergoing treatment for problematic anger. Clinical implications will be discussed.

Positive emotions in caring for a spouse: a literature review

This article aimed at identifying the positive emotions connected to spouse caregiving and the advantages for spouse carers. Theoretically, the article is based on the concept of emotion and the assumptions of positive psychology. Data search is conducted via electronic literature databases and the analysis method is partly theory-driven and partly inductive content classification. Our analyses discover and clarify the concepts associated with positive emotions in caring, such as the gains of caregiving, benefit-finding, finding meaning, personal growth, post-traumatic growth and resilience. We also utilise a conceptual framework to describe positive emotions in caregiving, and the identified advantages of positive emotions in spouse caregiving include distress buffering, mediation in coping with stress, increased quality of life and well-being, and finding a sense of purpose. Finally, spouse care is seen in this article as a challenging life situation which at best can support personal growth, if the processing of both positive and negative emotions is included in daily life. Hence, the service and support system should be developed further by utilising the findings of positive psychology as well as studies of personal growth.

Military Chronic Musculoskeletal Pain and Psychiatric Comorbidity: Is Better Pain Management the Answer?

Chronic musculoskeletal pain, such as low back pain, often appears in the presence of psychiatric comorbidities (e.g., depression, posttraumatic stress disorder (PTSD)), especially among U.S. military service members serving in the post-9/11 combat era. Although there has been much speculation about how to best address pain/trauma psychiatric symptom comorbidities, there are little available data to guide practice. The present study sought to examine how pre-treatment depression and PTSD influence outcomes in a functional restoration pain management program using secondary analysis of data from the Department of Defense-funded Functional and Orthopedic Rehabilitation Treatment (FORT) trial. Twenty-eight FORT completers were analyzed using a general linear model exploring how well depression and PTSD symptoms predict post-treatment pain (Visual Analog Scale (VAS) pain rating), disability (Oswestry Disability Index; Million Visual Analog Scale), and functional capacity (Floor-to-Waist and Waist-to-Eye Level progressive isoinertial lifting evaluation scores) in a sample of active duty military members with chronic musculoskeletal pain and comorbid depression or PTSD symptoms. Analysis revealed that pre-treatment depression and PTSD symptoms did not significantly predict rehabilitation outcomes from program completers. Implications of these findings for future research on trauma-related pain comorbidities are discussed.

Body-Related Emotions in Posttraumatic Stress Disorder Following Childhood Sexual Abuse

Traumatic experiences are associated with emotions such as anxiety, shame, guilt, disgust, and anger. For patients who have experienced child sexual abuse, these emotions might be triggered by perceptions of their own body. The aim of this study was to investigate the extent of the association of the body to traumatic experiences and to discern the emotions linked to trauma-associated body areas. Ninety-seven female participants were assigned to four groups: post-traumatic stress disorder following child sexual abuse with co-occurring borderline personality disorder, post-traumatic stress disorder following child sexual abuse without co-occurring borderline personality disorder, borderline personality disorder without post-traumatic stress disorder, and healthy controls. Participants rated 26 body areas regarding their association with trauma and 7 emotions. Emotions were assessed by questionnaires. Results suggest that specific areas of the body are associated with trauma and linked to highly aversive emotions. In post-traumatic stress disorder patients, the areas associated with highly negative emotions were the pubic region and inner thighs. Thus, the patient's body may act as a trigger for traumatic memories.

Pilot study of a compassion meditation intervention in chronic pain

BACKGROUND

The emergence of anger as an important predictor of chronic pain outcomes suggests that treatments that target anger may be particularly useful within the context of chronic pain. Eastern traditions prescribe compassion cultivation to treat persistent anger. Compassion cultivation has been shown to influence emotional processing and reduce negativity bias in the contexts of emotional and physical discomfort, thus suggesting it may be beneficial as a dual treatment for pain and anger. Our objective was to conduct a pilot study of a 9-week group compassion cultivation intervention in chronic pain to examine its effect on pain severity, anger, pain acceptance and pain-related interference. We also aimed to describe observer ratings provided by patients' significant others and secondary effects of the intervention.

METHODS

Pilot clinical trial with repeated measures design that included a within-subjects wait-list control period. Twelve chronic pain patients completed the intervention (F= 10). Data were collected from patients at enrollment, treatment baseline and post-treatment; participant significant others contributed data at the enrollment and post-treatment time points.

RESULTS

In this predominantly female sample, patients had significantly reduced pain severity and anger and increased pain acceptance at post-treatment compared to treatment baseline. Significant other qualitative data corroborated patient reports for reductions in pain severity and anger.

CONCLUSIONS

Compassion meditation may be a useful adjunctive treatment for reducing pain severity and anger, and for increasing chronic pain acceptance. Patient reported reductions in anger were corroborated by their significant others. The significant other corroborations offer a novel contribution to the literature and highlight the observable emotional and behavioral changes in the patient participants that occurred following the compassion intervention. Future studies may further examine how anger reductions impact relationships with self and others within the context of chronic pain.

Alleviation of Moral Disgust, Shame, and Guilt in Posttraumatic Stress Reactions

Research suggests that moral disgust, shame, and guilt are present in posttraumatic psychopathology. However, it is unclear that these emotional states are responsive to empirically supported interventions for posttraumatic stress symptoms (PTSS). This study explored the relations among moral disgust, shame, guilt, and PTSS, and examined comprehensive distancing (CD) as a novel intervention for these emotional states in undergraduates with elevated PTSS. Participants were randomly assigned to use a CD or a cognitive challenge task in response to personalized scripts of a traumatic event. Both interventions were associated with decreases in disgust, moral disgust, shame, and guilt. Contrary to predictions, there were no significant differences between the exercises in the reduction of negative emotions. In addition, PTSS severity was correlated with trauma-related guilt as well as state guilt and shame, but not trait or state measures of disgust or moral disgust. This proof of concept project sets the stage for further research examining CD as an alternative or adjunctive intervention for posttraumatic stress reactions with strong features of moral disgust, shame, and guilt.

[Changes in basic emotion recognition in patients with chronic low back pain. A cross-sectional study analyzing emotion recognition and alexithymia]

BACKGROUND

Persistent chronic pain leads to cortical changes in areas involved in the recognition of emotions. Wand et al. suggest a close correlation between the affective pain component and the extent to which these changes occur. As a consequence, the emotion profile may be influenced and difficulties in emotional communication may arise.

MATERIALS AND METHODS

A total of 49 patients with chronic low back pain (CLBP) were classified as grade 1 + 2 or 3 + 4 using the Graded Chronic Pain Scale (GCPS) questionnaire. In all patients, the ability to recognize basic emotions coded through facial expression was assessed using the Facially Expressed Emotion Labeling (FEEL) test. Furthermore, the Toronto Alexithymia Scale-26 (TAS-26) was used to assess if the patients showed signs of alexithymia. Data of the GCPS grade 3 + 4 (n = 35) group were analyzed.

RESULTS

Findings of the FEEL test indicate that the GCPS grade 3 + 4 group recognized the basic emotion 'surprise' significantly more often (p = 0.001) and showed a higher level of currently perceived anger than unaffected subjects. The TAS-26 showed that 28.5 % of the patients with CLBP were alexithym.

CONCLUSION

The results suggest changes in the recognition of emotions and that patients with CLBP show signs of alexithymia. Further studies with larger sample sizes are required to confirm the detected trends.

Emotions and emotion regulation in survivors of childhood sexual abuse: the importance of "disgust" in traumatic stress and psychopathology

BACKGROUND

Childhood sexual abuse (CSA) has the potential to compromise socio-emotional development of the survivor resulting in increased vulnerability to difficulties regulating emotions. In turn, emotion regulation is thought to play a key part in a number of psychological disorders which CSA survivors are at increased risk of developing. A better understanding of the basic emotions experienced in this population and emotion regulation strategies will inform current treatment.

OBJECTIVE

This paper examines the relationships between type of emotions experienced, emotion regulation strategies, and psychological trauma symptoms in a sample of survivors of CSA.

METHOD

A consecutive case series of CSA survivors (n=109) completed the Basic Emotions Scale (BES)-Weekly, General, and Coping versions; the Regulation of Emotions Questionnaire; the Post-traumatic Stress Checklist-Civilian Version (PCL-C); and the Clinical Outcomes in Routine Evaluation Outcome Measure.

RESULTS

Significantly higher levels of disgust than other levels of emotions were reported on the weekly version of the BES. In addition, significantly higher levels of disgust and lower levels of happiness were reported on the BES-General subscale. Regression analyses revealed that sadness, fear, disgust, and external dysfunctional coping strategies predicted global post-traumatic stress disorder and re-experiencing symptomatology measured by the PCL-C. Global distress, as measured by CORE, was predicted by the emotions of sadness, disgust, and low happiness, as well as dysfunctional regulatory strategies. In addition, preliminary exploratory factor analyses supported the structure of all three versions of the BES, with disgust explaining the largest percentage of variance, followed by happiness.

CONCLUSIONS

The findings highlight the utility of profiling basic emotions in understanding the strong associations between emotional phenomena, particularly the emotion of disgust and psychopathology in CSA survivors.

Standardized mirror confrontation: Body-related emotions, cognitions and level of dissociation in patients with Posttraumatic Stress Disorder after childhood sexual abuse

BACKGROUND

A criterion for Posttraumatic Stress Disorder (PTSD) is the avoidance of trauma-associated stimuli that trigger emotional suffering. First studies on body image of patients with PTSD after childhood sexual abuse (CSA) support the hypothesis that awareness of the own body triggers emotional suffering.

METHODS

Body-related emotions, cognitions and level of dissociation of n = 17 patients meeting DSM-IV criteria for PTSD and n = 29 healthy controls (HCs) during a standardized mirror confrontation while wearing a standard bikini were assessed.

RESULTS

It was shown that expecting to be and while being confronted with one's own body, patients with PTSD showed significantly stronger negative emotionality and cognitions as well as higher dissociative states as compared to HCs.

CONCLUSIONS

Findings suggest that in patients with PTSD after CSA, one's own body might function as a stimulus that leads to aversive emotional responses, negative cognitions and dissociative states. The elaboration of treatment for PTSD should consider these body-related aspects, e.g., by investigating the effects of body exposure.

Psychological resilience, pain catastrophizing, and positive emotions: perspectives on comprehensive modeling of individual pain adaptation

Pain is a complex construct that contributes to profound physical and psychological dysfunction, particularly in individuals coping with chronic pain. The current paper builds upon previous research, describes a balanced conceptual model that integrates aspects of both psychological vulnerability and resilience to pain, and reviews protective and exacerbating psychosocial factors to the process of adaptation to chronic pain, including pain catastrophizing, pain acceptance, and positive psychological resources predictive of enhanced pain coping. The current paper identifies future directions for research that will further enrich the understanding of pain adaptation and espouses an approach that will enhance the ecological validity of psychological pain coping models, including introduction of advanced statistical and conceptual models that integrate behavioral, cognitive, information processing, motivational and affective theories of pain.

Disgust, mental contamination, and posttraumatic stress: unique relations following sexual versus non-sexual assault

Disgust and mental contamination (or feelings of dirtiness and urges to wash in the absence of a physical contaminant) are increasingly being linked to traumatic event exposure and posttraumatic stress (PTS) symptomatology. Evidence suggests disgust and mental contamination are particularly relevant to sexual assault experiences; however, there has been relatively little direct examination of these relations. The primary aim of the current study was to assess disgust and mental contamination-based reactivity to an individualized interpersonal assault-related script-driven imagery procedure. Participants included 22 women with a history of traumatic sexual assault and 19 women with a history of traumatic non-sexual assault. Sexual assault and PTS symptom severity predicted greater increases in disgust, feelings of dirtiness, and urges to wash in response to the traumatic event script. Finally, assault type affected the association between PTS symptom severity and increases in feelings of dirtiness and urges to wash in response to the traumatic event script such that these associations were only significant among sexually assaulted individuals. These findings highlight the need for future research focused on elucidating the nature of the relation between disgust and mental contamination and PTS reactions following various traumatic events.

Specificity of fear and disgust experienced during traumatic interpersonal victimization in predicting posttraumatic stress and contamination-based obsessive-compulsive symptoms

Emerging evidence has documented comorbidity between posttraumatic stress disorder (PTSD) and obsessive-compulsive disorder (OCD) among individuals with a history of traumatic events. There is growing recognition of the importance of disgust in each of these conditions independently. No study, however, has examined the potential role of disgust in these conditions following traumatic event exposure. The current study examined the unique role of peritraumatic fear, self-focused disgust, and other-focused disgust in predicting posttraumatic stress symptoms and contamination-based OC symptoms among 49 adult women (M(age)=28.37, SD=13.86) with a history of traumatic interpersonal victimization. Results demonstrated that intensity of peritraumatic self-focused disgust was significantly related to contamination-based OC symptoms while peritraumatic fear and other-focused disgust were related to posttraumatic stress symptoms. These results highlight the need for future research aimed at elucidating the nature of the association between disgust experienced during traumatic events and subsequent psychopathology.
