Pleasurable emotions and internalizing psychopathology: A multi-study examination of specificity and alternative explanations.

OBJECTIVES: Past research has been inconclusive regarding the specificity of associations between discrete pleasurable emotions and internalizing symptoms. Contentment may be especially relevant to depression, whereas tranquillity may be especially relevant to worry. The goal of the current research was to clarify the mixed findings regarding the relation between pleasure deficits and internalizing psychopathology. METHODS: Participants from three samples (Total N = 757) completed alternative measures of depression and pleasurable emotions. Participants in Study 1 also completed a measure of anticipatory and consummatory pleasure, and close peers to a subset of participants (N = 64) reported their perceptions of participants' depression severity. Participants in Studies 2 and 3 also completed a measure of worry. RESULTS: Across the three samples, contentment was significantly negatively associated with self-reported depression. This association could not be accounted for by tranquillity, cheerfulness, anticipatory pleasure, or consummatory pleasure. Contentment was also strongly negatively associated with peer-reported depression. Contentment was more strongly associated with depression than was cheerfulness. However, the strength of the association between contentment and depression relative to the strength of the association between tranquillity and depression depended on how contentment and depression were measured. Conversely, tranquillity was more strongly associated with worry than were contentment or cheerfulness. CONCLUSIONS: This study provides further evidence of the potential importance of the role of contentment in depression and tranquillity in worry. It may be useful to attend to contentment when assessing and treating depression and to attend to tranquillity when assessing and treating elevated worry.

Exploring phenotypic overlap across schizotypy and autism spectrum conditions in American and Chinese young adults.

Competing theories have been proposed to explain the considerable overlap in social-cognitive features and risk factors across schizotypy and autism spectrum conditions (ASCs). Six previous factor analyses have been reported in the literature, yet all have major limitations; evidence for the clear superiority of any of the competing theories is insufficient and warrants further investigation. The primary aim of the present research was to identify dimensions that cut across schizotypy and ASCs while addressing limitations of past research. Data were collected from three independent samples (n = 1006, 544, and 2469) in the U.S. and China using the Autism-Spectrum Quotient, the Schizotypal Personality Questionnaire, and the Wisconsin Schizotypy Scales. Exploratory factor analyses in Sample 1 identified an interpretable three-factor structure, which was replicated in Samples 2 and 3 using confirmatory factor analyses. We found consistent evidence for three dimensions (Aberrant Salience, Asociality, and Concrete Thinking) underlying schizotypy and ASCs. This three-dimension model is consistent with a common vulnerability model of schizotypy and ASCs. Implications of these findings for the schizotypy and ASCs literature are discussed.

Misophonia and Hearing Comorbidities in a Collegiate Population.

OBJECTIVES: Misophonia is a little-understood disorder in which certain sounds cause a strong emotional response in those who experience it. People who are affected by misophonia may find that noises like loud chewing, pen clicking, and/or sniffing trigger intense frustration, anger, or discomfort. The relationship of misophonia with other auditory disorders including loudness hyperacusis, tinnitus, and hearing loss is largely underexplored. This project aimed to investigate the prevalence and hearing-health comorbidities of misophonia in a college-aged population by using an online survey. DESIGN: A total of 12,131 undergraduate and graduate students between the ages of 18 and 25 were given the opportunity to answer an in-depth online survey. These students were sampled in a roughly 50 of 50 sex distribution. The survey was created using Qualtrics and included the following components: electronic consent, demographics questionnaire, Misophonia Questionnaire (MQ), Khalfa's Hyperacusis Questionnaire (HQ), Tinnitus and Hearing Survey, and Tinnitus Functional Index (TFI). To be eligible for compensation, answers for each of the above components were required, with the exception of the TFI, which was only presented to students who indicated that they experienced tinnitus. Respondents were determined to have high or possible likelihood of having misophonia if they gave specific answers to the MQ's Emotion and Behavior Scale or the MQ Severity Scale. RESULTS: After excluding duplicate responses and age-related outliers, 1,084 responses were included in the analysis. Just over 20% (n = 217) of the sample was determined to have a high or probable likelihood of having misophonia. The sample was primarily White, female, and of mid-to-high socioeconomic status. There was a strong positive correlation between MQ total scores and HQ total scores. High likelihood misophonia status showed a significant relationship with self-reported hearing loss and tinnitus. No statistically significant relationship was found between misophonia and age, ethnicity, or socioeconomic status. MQ total scores differed significantly when separating respondents by sex, self-reported tinnitus, and loudness hyperacusis. White respondents had significantly higher MQ total scores than Asian/Asian American respondents. CONCLUSIONS: The estimated prevalence of misophonia was about 8% to 20% of the sample, which agrees with most of the currently published research examining misophonia symptoms in collegiate populations. Results of data analysis suggest that misophonia severity may be related to loudness hyperacusis, sex, and possibly tinnitus. Future studies are needed to further examine the characteristics of these relationships, possibly in populations more optimized to reflect the general population or those with hearing-health disorders.

The interactive effects of different facets of threat uncertainty and cognitive load in shaping fear and anxiety responses.

A large body of research indicates that exaggerated response to uncertainty of a future threat is at the core of anxiety and related disorders, underscoring the need for a better understanding of the underlying mechanisms. Although behavioral and neuroimaging studies have suggested a close relationship between uncertainty responses and cognitive control, little is known about what elements of uncertainty are more or less vulnerable to cognitive modulation in shaping aversive responses. Leveraging a novel paradigm, an n-back working memory task embedded within a modified threat-of-shock paradigm, we examined how the influences of different facets of uncertainty (i.e., occurrence and timing) on psychophysiological responses were modulated by cognitive load. Psychophysiological responses were assessed using the acoustic startle reflex. Replicating prior work, the effects of cognitive load and temporal unpredictability of threat on startle responses were evident. The effect of occurrence unpredictability appears to depend on other factors. Under low cognitive load, startle response was potentiated when both the occurrence and the timing of threat were predictable. Under high cognitive load, startle response was significantly reduced, especially when a threat context involves uncertainty in both temporal and probability domains. These observations provide a framework for refining the model of fear and anxiety and for understanding the etiology of psychological disorders characterized by maladaptive uncertainty responses.

An experimental and simulation study of the impact of emotional information on analogical reasoning.

We investigated whether and how emotional information would affect analogical reasoning. We hypothesized that task-irrelevant emotional information would impair performance whereas task-relevant emotional information would enhance it. In Study 1, 233 undergraduates completed a novel version of the People Pieces Task (Emotional Faces People Task), an analogical reasoning task in which the task characters displayed emotional or neutral facial expressions (within-participants). The emotional faces were relevant or irrelevant to the task (between-participants). We simulated the behavioral results using the Learning and Inference with Schemas and Analogies (LISA) model of relational reasoning. LISA is a neurally plausible, symbolic-connectionist computational model of analogical reasoning. In comparison to neutral trials, participants were slower but more accurate on emotion-relevant trials, and were faster but less accurate on emotion-irrelevant trials. Simulations using the LISA model demonstrated that it is possible to account for the effects of emotional information on reasoning in terms of how emotional stimuli attract attention during a reasoning task. In Study 2, 255 undergraduates completed the Emotional Faces People Task at either a high- or low-working memory load. The high working memory load condition of Study 2 replicated the findings of Study 1, showing that participants were more accurate on emotion-relevant trials than on emotion-irrelevant trials; in Study 2, this increased accuracy could not be accounted for by a speed-accuracy tradeoff. The working memory manipulation influenced the manner in which the congruence (with the correct answer) of emotion-irrelevant emotion influenced performance. Simulations using the LISA model showed that manipulating the salience of emotion, the error penalty, as well as vigilance (which determines the likelihood that LISA will notice it has attended to an irrelevant relation), could reasonably reproduce the behavioral results of both low and high working memory load conditions of Study 2.

Clarity of Emotions and Goals: Exploring Associations with Subjective Well-Being Across Adulthood.

Despite declines in cognition associated with age, emotional health tends to increase. However, extant studies find few differences in the type or number of emotion regulation strategies used by older compared to younger adults. This study tested the hypothesis that older adults have greater clarity of their emotions and goals compared to younger adults. Participants (total N = 709, ages 18-81) recruited in age-stratified samples completed measures of emotional clarity, goal clarity, depression, and life satisfaction. Results suggested that emotional clarity and goal clarity are positively correlated factors, with emotional clarity showing the lowest levels in emerging adults and highest levels in older adults. Goal clarity was lowest among emerging adults, but only small differences were found between middle and older adults. Across adulthood both emotional clarity and goal clarity were linked to lower depressive symptoms and greater life satisfaction. Limitations include data being cross-sectional and self-report based and the youngest sample being recruited differently from the older samples, but the results raise the possibility of developmental changes in emotional clarity across adulthood.

Where to Look? Alcohol, Affect, and Gaze Behavior During a Virtual Social Interaction.

COVID-19 forced social interactions to move online. Yet researchers have little understanding of the mental health consequences of this shift. Given pandemic-related surges in emotional disorders and problematic drinking, it becomes imperative to understand the cognitive and affective processes involved in virtual interactions and the impact of alcohol in virtual social spaces. Participants (N=246) engaged in an online video call while their gaze behavior was tracked. Prior to the interaction, participants were randomly assigned to receive an alcoholic or control beverage. Participants' affect was repeatedly assessed. Results indicated that a proportionally larger amount of time spent gazing at oneself (vs. one's interaction partner) predicted significantly higher negative affect after the exchange. Further, alcohol independently increased self-directed attention, failing to demonstrate its typically potent social-affective enhancement in this virtual context. Results carry potential implications for understanding factors that increase risk for hazardous drinking and negative affect in our increasingly virtual world.

Testing a theory-driven factor structure of the autism-spectrum quotient.

The Autism-Spectrum Quotient (AQ) is a popular instrument used to assess the degree to which individuals exhibit features of autism spectrum conditions (ASC). The current study aimed to develop a theory-driven factor structure of the AQ that would fit as well across samples as the 12 previously proposed factor structures, all of which, except for the original Baron-Cohen model, had been developed on the basis of exploratory factor analysis (EFA) or principal component analysis. We first proposed a six-factor solution: (1) social anhedonia; (2) interest in details/patterns; (3) imagination ability; (4) desire for predictability/routine; (5) social cognition; and (6) social discourse convention. We tested the six-factor structure and made final item selections (27 items) with EFA using data from college students (n = 503). Then, we empirically tested alternative factor structure models in three other independent samples (ns = 503; 1263; 1641) using confirmatory factor analysis. Results indicated that our model fit as well, if not better, than all of the other models across samples, regardless of parameter estimation methods and software packages. Overall, the theory-driven replicable six-factor structure that we report holds the potential to be used to measure the six domains of features that we identified in the AQ. LAY SUMMARY: Questionnaire measures of autism spectrum conditions have typically been used to measure approximately four broad dimensions. Our study suggests that the Autism-Spectrum Quotient can be used to measure six more narrowly defined dimensions: social anhedonia, interest in details/patterns, imagination ability, desire for predictability/routine, social cognition, and social discourse convention. Additional work is needed to develop measures of a much wider variety of autism spectrum features.

Strangulation as an Acquired Brain Injury in Intimate-Partner Violence and Its Relationship to Cognitive and Psychological Functioning: A Preliminary Study.

OBJECTIVE: The aim of this work was to examine the relationship between strangulation-related alterations in consciousness (AIC) and cognitive and psychological outcomes in women who have experienced intimate partner violence (IPV). SETTING: Participants were recruited from a variety of settings, including women's shelters and support programs. PARTICIPANTS: A total of 99 women were enrolled in the study. After applying exclusion criteria for factors that could mask or confound the effects of strangulation, 52 women remained for analyses. DESIGN: Cross-sectional, retrospective. MAIN MEASURES: We used several cognitive measures to assess learning, long-term and working memory, visuomotor speed, cognitive flexibility, and nonverbal cognitive fluency as well as several psychological measures to assess posttraumatic stress symptomatology, general distress, worry, anhedonic depression, and anxious arousal. We also used the Brain Injury Severity Assessment interview to examine the association between strangulation-related AICs and these measures of cognitive and psychological functioning. RESULTS: Women who had experienced strangulation-related AICs performed more poorly on a test of long-term memory (P < .03) and had higher levels of depression (P < .03) and posttraumatic stress symptomatology (P < .02) than women who had not experienced strangulation-related AIC. When controlling for potential confounding variables, including number of IPV-related traumatic brain injuries, women who had experienced strangulation also performed more poorly on a measure of working memory. CONCLUSION: This is the first report to assess strangulation in this manner and demonstrate links to cognitive and psychological functioning. These preliminary data contribute to our knowledge of strangulation and its effects on women who have experienced IPV.

Proneness for and aversion to self-conscious emotion in posttraumatic stress.

OBJECTIVE: Theory suggests that self-conscious emotions (guilt and shame) may play a role in the development/maintenance of posttraumatic stress. Propensities to experience these emotions (i.e., proneness) may confer risk for posttraumatic stress, while difficulties tolerating or coping with them (i.e., aversion) may maintain or exacerbate symptoms. However, no research to date has examined the importance of guilt aversion or shame aversion in posttraumatic stress. METHOD: A total of 336 participants provided open-ended information on their experience of potentially traumatic events; a team of trained raters determined that a final sample of 186 participants had a clinically significant history of trauma. These participants completed measures of posttraumatic stress, along with measures of proneness for and aversion to both guilt and shame. Negative affect and experiential avoidance were assessed as covariates. RESULTS: Zero-order correlations indicated that guilt-proneness and guilt aversion were not associated with posttraumatic stress. By contrast, shame-proneness was associated with posttraumatic stress over and above trait negative affect and experiential avoidance. Moreover, a significant interaction revealed that shame-proneness was only associated with posttraumatic stress when shame aversion was high. CONCLUSIONS: Results suggest that people high in shame-proneness, and therefore likely to experience shame in response to traumatic events, may experience greater posttraumatic stress if they are shame averse. If this is the case, addressing shame directly and teaching better skills for regulating it may be an important treatment goal for some individuals with posttraumatic stress.

Intensity, frequency, and differentiation of discrete emotion categories in daily life and their associations with depression, worry, and rumination.

Previous research examining links between psychopathology and emotions in daily life have largely focused on disorder-specific patterns of mean-level positive and negative affect. In this study, we examined three transdiagnostic dimensions of psychopathology, namely depression, worry, and rumination, and their association with the intensity, frequency, and differentiation of discrete emotion categories endorsed in daily life. Three independent samples of young adults (total n = 614) completed baseline measures assessing depression, worry, and rumination followed by a 1-week daily diary procedure. Daily diaries assessed the following emotion categories: "tranquility," "contentment," "happiness," "excitement," "pride," "sadness," "boredom," "guilt," "fear," and "anger." Intensity, frequency, and differentiation were all calculated from daily emotion ratings. Psychopathology was associated with intensity and frequency of pleasant emotion, with intensity showing stronger associations. Intensity of contentment and happiness were most strongly associated with all three forms of psychopathology, whereas pride had the weakest associations. Psychopathology was associated with intensity and frequency of unpleasant emotions, with frequency tending to show stronger associations. Frequency of sadness and boredom were most strongly associated with depression, whereas the frequency and intensity of fear were similarly associated with depression and worry. Although psychopathology was associated with pleasant and unpleasant emotion differentiation, to our surprise, effect sizes were negligible to small. Clinical implications and recommendations for future research are discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Cultivating Affective Resilience: Proof-of-Principle Evidence of Translational Benefits From a Novel Cognitive-Emotional Training Intervention.

Available evidence highlights the importance of emotion regulation (ER) in psychological well-being. However, translation of the beneficial effects of ER from laboratory to real-life remains scarce. Here, we present proof-of-principle evidence from a novel cognitive-emotional training intervention targeting the development of ER skills aimed at increasing resilience against emotional distress. This pilot intervention involved training military veterans over 5-8 weeks in applying two effective ER strategies [Focused Attention (FA) and Cognitive Reappraisal (CR)] to scenarios presenting emotional conflicts (constructed with both external and internal cues). Training was preceded and followed by neuropsychological, personality, and clinical assessments, and resting-state functional MRI data were also collected from a subsample of the participants. Results show enhanced executive function and psychological well-being following training, reflected in increased working memory (WM), post-traumatic growth (PTG), and general self-efficacy (GSE). Brain imaging results showed evidence of diminished bottom-up influences from emotional and perceptual brain regions, along with evidence of normalized functional connectivity in the large-scale functional networks following training. The latter was reflected in increased connectivity among cognitive and emotion control regions and across regions of self-referential and control networks. Overall, our results provide proof-of-concept evidence that resilience and well-being can be learned through ER training, and that training-related improvements manifested in both behavioral change and neuroplasticity can translate into real-life benefits.

The relations between pleasurable emotions and depression: Exploring the potential significance of contentment.

BACKGROUND: Previous research has found that the diminished ability to experience pleasure is a common feature of depression, but has not examined whether depression is associated equally strongly with the different types of pleasurable emotions. Contentment, which has been found to be especially strongly associated with life satisfaction and is associated with a sense of completeness or completion, was expected to be especially relevant to depression. METHODS: In two studies, participants (N = 70, and N = 109), who were receiving outpatient treatment, completed self-report measures of depression, contentment, tranquility, and cheerfulness. Worry and suicidality were also measured, in Studies 1 and 2, respectively. RESULTS: As hypothesized: (a) contentment was associated as strongly with depression as was cheerfulness; (b) contentment was more strongly associated with depression than was tranquility; (c) contentment was more strongly associated with depression than it was with worry; and (d) contentment was associated with suicidality even after taking into account depression severity, cheerfulness and tranquility. LIMITATIONS: The present research relied on self-report. Because both studies employed cross-sectional designs, conclusions regarding causality cannot be drawn. CONCLUSIONS: Contentment is associated with depression, even after taking into account other pleasurable emotions. The present findings raise the possibility that attending to different types of pleasurable emotions, such as contentment, may be important for understanding the different potential pathways to depression, and may be capable of predicting differential responses to alternative treatments for depression.

Emotional Awareness in Daily Life: Exploring Its Potential Role in Repetitive Thinking and Healthy Coping.

Cross-sectional research has found that emotional awareness, which is composed of one's emotional clarity and attention to emotions, is associated with psychopathology, emotion regulation, and coping. Not surprisingly then, emotional awareness is often a target of cognitive and behavioral therapies. However, little is known about what emotional awareness is related to in daily life, which would inform how and for whom emotional awareness training should be conducted in therapeutic settings. The goal of the current studies was to examine associations among facets of emotional awareness and repetitive thinking (i.e., rumination, worry, and reflection), emotion regulation, and coping in daily life. We conducted two 7-day daily diary studies (n = 172 in Study 1, n = 211 in Study 2) measuring daily experiences of repetitive negative thinking, emotion regulation efforts, and coping. Multilevel models showed that trait levels of emotional clarity were negatively associated, at the between-person level, with daily levels of repetitive negative thinking and positively associated with active coping. Additionally, daily levels of emotional clarity were associated, at the within-person level, with worrying and active coping, whereas daily levels of attention to emotions were associated, at the within-person level, with reflection. Theoretical and clinical implications for emotional awareness, particularly emotional clarity, are discussed.

Examining the latent structure of emotional awareness and associations with executive functioning and depression.

Emotional awareness is comprised of dispositions towards and knowledge about one's emotions. Executive functions (EF) are cognitive processes that organise and guide behaviour towards one's goals. Both emotional awareness and EF play a role in processes such as emotion regulation and are risk factors for the development and maintenance of depression. Although previous research suggests that aspects of emotional awareness are related to EF, methodological and measurement limitations within the available literature make it difficult to clearly understand how they are associated. In this registered report, we examined the extent to which task-based measures of a specific EF process, shifting, are differentially related to unique facets of emotional awareness (i.e. emotional clarity of type, emotional clarity of source, voluntary attention to emotions, and involuntary attention to emotions), and to what extent EF and emotional awareness are related to depression. Using structural equation modelling, we found evidence that emotional clarity of type was associated with greater shifting cost. Shifting was not associated with any other facet of emotional awareness. Depression was linked to lower emotional clarity of type, higher involuntary attention to emotions, but not poorer EF performance. We discuss how emotional awareness and EF may be uniquely related to depression.

Empathic accuracy: Associations with prosocial behavior and self-insecurity.

Empathic accuracy, or the degree to which one accurately understands another person's emotions, is widely thought to be related to better social functioning. However, empirical tests of this assumed relationship are quite scarce. We tested the hypotheses that people higher in empathic accuracy would be more likely to engage in prosocial behavior and report lower self-insecurity (rejection of their own weaknesses). In a large sample (N = 211) of undergraduates, we administered behavioral measures of empathic accuracy and helping, and self-reported self-insecurity. We found that people who were more accurate in detecting others' negative emotions were significantly more likely to help a confederate in need, and reported marginally lower self-insecurity. We found a nonsignificant association between empathic accuracy of positive emotions and helping, and no association between empathic accuracy of positive emotions and self-insecurity. Our findings suggest accurate emotion perception and healthy self-evaluation may be important for being prosocial. We discuss implications for social emotion regulation and relationships.

Acts of omission, altered worldviews, and psychological problems among military veterans.

OBJECTIVE: The present study explored acts of omission (i.e., inactions) among military service members. We also investigated whether the meanings and interpretations that service members assign to their actions and inactions, particularly alterations to their conceptualization of themselves, others, and the world (i.e., altered worldviews) would be associated with psychological problems (specifically, depression, suicidality, posttraumatic stress disorder [PTSD], and alcohol use). METHOD: A sample of 50 Iraq/Afghanistan military veterans (8% female) completed questionnaires measuring their (in)actions and the meanings and interpretations attached to those (in)actions. They also completed questionnaires measuring PTSD, depression, suicidality, alcohol use, and combat/postcombat experience. RESULTS: Higher levels of acts of omission were associated with higher levels of altered worldviews and psychological problems. Altered worldviews were strongly associated with PTSD, depression, and suicidality, even after taking into account age, gender, combat/postcombat experiences, and guilt/shame. CONCLUSION: Altered worldviews and acts of omission were strongly associated with psychological problems. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

PTSD symptoms and overt attention to contextualized emotional faces: Evidence from eye tracking.

Abnormal patterns of attention to emotional faces and images are proposed by theories of posttraumatic stress disorder (PTSD), and this has been demonstrated empirically. However, few studies have examined how PTSD symptoms are associated with attention to emotional faces in the context of emotional background images. Eye tracking data were collected from seventy-eight undergraduates with a history of experiencing at least one traumatic event as they completed the Contextual Recognition of Affective Faces Task (CRAFT; Milanak and Berenbaum, 2014), which requires subjects to identify the emotion depicted by faces superimposed on an emotional background image. Greater PTSD symptom severity was associated with more time spent looking at background contexts and less time looking at target faces. This is consistent with greater susceptibility to distraction by task-irrelevant emotional stimuli. The duration of each gaze fixation upon fear faces was shorter for those with greater PTSD symptoms, and this pattern was marginally significant for disgust faces. These findings suggest that PTSD symptoms may relate to greater attention toward non-facial background scenes and less attention toward facial stimuli, especially when conveying a fear or disgust expression.

The association between PTSD and facial affect recognition.

The major aims of this study were to examine how, if at all, having higher levels of PTSD would be associated with performance on a facial affect recognition task in which facial expressions of emotion are superimposed on emotionally valenced, non-face images. College students with trauma histories (N = 90) completed a facial affect recognition task as well as measures of exposure to traumatic events, and PTSD symptoms. When the face and context matched, participants with higher levels of PTSD were significantly more accurate. When the face and context were mismatched, participants with lower levels of PTSD were more accurate than were those with higher levels of PTSD. These findings suggest that PTSD is associated with how people process affective information. Furthermore, these results suggest that the enhanced attention of people with higher levels of PTSD to affective information can be either beneficial or detrimental to their ability to accurately identify facial expressions of emotion. Limitations, future directions and clinical implications are discussed.

Did the DSM-5 Improve the Traumatic Stressor Criterion?: Association of DSM-IV and DSM-5 Criterion A with Posttraumatic Stress Disorder Symptoms.

OBJECTIVE: A recent meta-analysis found that DSM-III- and DSM-IV-defined traumas were associated with only slightly higher posttraumatic stress disorder (PTSD) symptoms than nontraumatic stressors. The current study is the first to examine whether DSM-5-defined traumas were associated with higher levels of PTSD than DSM-IV-defined traumas. Further, we examined theoretically relevant event characteristics to determine whether characteristics other than those outlined in the DSM could predict PTSD symptoms. METHOD: One hundred six women who had experienced a trauma or significant stressor completed questionnaires assessing PTSD, depression, impairment, and event characteristics. Events were rated for whether they qualified as DSM-IV and DSM-5 trauma. RESULTS: There were no significant differences between DSM-IV-defined traumas and stressors. For DSM-5, effect sizes were slightly larger but still nonsignificant (except for significantly higher hyperarousal following traumas vs. stressors). Self-reported fear for one's life significantly predicted PTSD symptoms. CONCLUSIONS: Our results indicate that the current DSM-5 definition of trauma, although a slight improvement from DSM-IV, is not highly predictive of who develops PTSD symptoms. Our study also indicates the importance of individual perception of life threat in the prediction of PTSD.
