Although there is a strong and consistent association between social support and posttraumatic stress disorder (PTSD), the directionality of this association has been debated, with some research indicating that social support protects against PTSD symptoms, whereas other research suggests that PTSD symptoms erode social support. The majority of studies in the literature have been cross-sectional, rendering directionality impossible to determine. Cross-lagged panel models overcome many previous limitations; however, findings from the few studies employing these designs have been mixed, possibly due to methodological differences including self-report versus clinician-administered assessment. The current study used a cross-lagged panel structural equation model to explore the relationship between social support and chronic PTSD symptoms over a 1-year period in a sample of 264 Iraq and Afghanistan veterans assessed several years after trauma exposure. Approximately a third of the sample met criteria for PTSD at the baseline assessment, with veterans’ trauma occurring an average of 6 years prior to baseline. Two separate models were run, with one using PTSD symptoms assessed via self-report and the other using clinician-assessed PTSD symptoms. Excellent model fit was found for both models. Results indicated that the relationship between social support and PTSD symptoms was affected by assessment modality. Whereas the self-report model indicated a bidirectional relationship between social support and PTSD symptoms over time, the clinician-assessed model indicated only that baseline PTSD symptoms predicted social support 1 year later. Results highlight that assessment modality is one factor that likely impacts disparate findings across previous studies. Theoretical and clinical implications of these findings are discussed, with suggestions for the growing body of literature utilizing these designs to dismantle this complex association. 相似文献

This study investigated infant predictors of early cognitive and emotional self-regulation from an intrinsic and caregiving environmental perspective. Sustained attention, reactive aspects of infant temperament, and maternal sensitivity were assessed at 10 months (n = 124) and early self-regulation (including executive functions, EF, and emotion regulation) was assessed at 18 months. The results indicated that sustained attention predicted early EF, which provide empirical support for the hierarchical framework of EF development, advocating early attention as a foundation for the development of cognitive self-regulation. Maternal sensitivity and surgency predicted emotion regulation, in that infants of sensitive mothers showed more regulatory behaviours and a longer latency to distress, whereas high levels of surgency predicted low emotion regulation, suggesting both the caregiving environment and temperament as important in the development of self-regulation. Interaction effects suggested high sustained attention to be a protective factor for children of insensitive mothers, in relation to emotion regulation. In addition, high levels of maternal sensitivity seemed to foster development of emotion regulation among children with low to medium levels of sustained attention and/or surgency. In all, our findings point to the importance of both intrinsic and extrinsic factors in infant development of self-regulation. 相似文献

Research indicates that exposure therapy is efficacious for combat-related posttraumatic stress disorder (PTSD) comorbid with traumatic brain injury (TBI) as is shown by reduced PTSD treatment outcome scores. What is unknown, however, is whether the process of fear extinction is attenuated in veterans with TBI history. Increased PTSD symptomatology and possible cognitive deficits associated with TBI sequelae may indicate additional or longer exposure sessions to achieve habituation and extinction comparable to individuals without TBI history. As such, a more extensive course of treatment may be necessary to achieve comparable PTSD treatment outcome scores for individuals with TBI history. Using a sample of veterans with combat-related PTSD, some of whom were comorbid for TBI, this study compared process variables considered relevant to successful treatment outcome in exposure therapy. Individuals with and without TBI demonstrated similar rates of fear activation, length and number of exposure sessions, within-session habituation, between-session habituation, and extinction rate; results remained consistent when controlling for differential PTSD symptomatology. Furthermore, results indicated that self-perception of executive dysfunction did not impact the exposure process. Results suggest that individuals with PTSD and TBI history engage successfully and no differently in the exposure therapy process as compared to individuals with PTSD alone. Findings further support exposure therapy as a first-line treatment for combat-related PTSD regardless of TBI history. 相似文献

Misophonia is characterized by extreme aversive reactions to certain classes of sounds. It has recently been recognized as a condition associated with significant disability. Research has begun to evaluate psychopathological correlates of misophonia. This study sought to identify profiles of psychopathology that characterize misophonia in a large community sample. A total of N = 628 adult participants completed a battery of measures assessing anxiety and anxiety sensitivity, depression, stress responses, anger, dissociative experiences, obsessive-compulsive symptoms and beliefs, distress tolerance, bodily perceptions, as well as misophonia severity. Profile Analysis via Multidimensional Scaling (PAMS) was employed to evaluate profiles associated with elevated misophonia and those without symptoms. Three profiles were extracted. The first two accounted for 70% total variance and did not show distinctions between groups. The third profile accounted for 11% total variance, and showed that misophonia is associated with lower obsessive-compulsive symptoms for neutralizing, obsessions generally, and washing compared to those not endorsing misophonia, and higher levels of obsessive-compulsive symptoms associated with ordering and harm avoidance. This third profile extracted also showed significant differences between those with and without misophonia on the scale assessing physical concerns (that is, sensitivity to interoceptive sensations) as assessed with the ASI-3. Further research is called for involving diagnostic interviewing and experimental methods to clarify these putative mechanisms associated with misophonia. 相似文献

Non-suicidal self-injury (NSSI) is commonly used by young adults to regulate emotional responses. Yet, experimental examination of how people who self-injure appraise and respond to emotional stimuli is limited. We examined appraisals of, and responses to, emotive images in young adults who did and did not self-injure, and assessed whether these were impacted by exposure to a stressor. Study 1 (N?=?51) examined whether participants differed in their appraisals of emotional images. Study 2 (N?=?78) assessed whether appraisals of images changed after exposure to the Trier Social Stress Test. Ratings of emotional valence and arousal were collected in both studies; skin conductance was measured as an indicator of physiological arousal in Study 2. In Study 1 participants reporting NSSI rated positively valenced images as less pleasant than participants not reporting NSSI. In Study 2, after acute stress, participants reporting NSSI displayed dampened physiological reactions to positive images whereas participants who did not self-injure displayed heightened physiological reactions to these and rated them as more pleasant. Individuals who self-injure seem less able to engage in strategic mood repair after exposure to stress compared to people who do not self-injure. 相似文献

ABSTRACTRumination and worry are two perseverative, negatively valenced thought processes that characterise depressive and anxiety disorders. Despite significant research interest, little is known about the everyday precipitants and consequences of rumination and worry. Using an experience sampling methodology, we examined and compared rumination and worry with respect to their relations to daily events and affective experience. Participants diagnosed with Major Depressive Disorder (MDD), Generalized Anxiety Disorder (GAD), co-occurring MDD–GAD, or no diagnosis carried an electronic device for one week and reported on rumination, worry, significant events, positive affect (PA), and negative affect (NA). Across the clinical groups, occurrences of everyday events predicted subsequent increases in rumination, but not worry. Further, higher momentary levels of rumination, but not worry, predicted subsequent decreases in PA and increases in NA. Thus, in these clinical groups, rumination was more susceptible to daily events and produced stronger affective changes over time. We discuss implications for theory and clinical intervention. 相似文献

ABSTRACTHarassment of Asian American (AA) women has received little attention in popular culture and academic research despite their long legacy of sexualized racial stereotyping (e.g., Geisha, sexually submissive; Shimizu, 2007) and additional risk of mistreatment due to their membership in both marginalized gender and racial groups (Beale, 1970; Settles & Buchanan, 2014). This study addresses this dearth of research using an intersectional theoretical framework to comprehensively examine sexual and racial harassment with a sample of AA women. Results validated the underlying factor structure of the Sexual Experiences Questionnaire (Fitzgerald, Gelfand, & Drasgow, 1995) and the Racial Acts, Crimes, and Experiences Scale (RACES; Bergman & Buchanan, 2008) for AA women. Additionally, our results replicated previous research indicating that participants often reported experiencing behaviors that constitute harassment, but did not label them as such. This supports the use of behavioral measures over items that require individuals to label their experiences as harassment. Finally, we examined the associations between these forms of harassment and two indicators of psychological well-being, depression, and posttraumatic stress (PTS). Our results found that gender harassment was associated with more depression, whereas unwanted sexual attention, sexual coercion, and racial harassment were associated with increased PTS. This supports the utility of including both sexual and racial harassment in providing a more nuanced understanding of AA women’s harassment experiences overall and the relationship of harassment to psychological well-being. We discuss theoretical and clinical implications of these findings. 相似文献

Is the centralization of potentially traumatic events always negative? An expansion of the Centrality of Events Scale 下载免费PDF全文
Carissa L. Broadbridge 《Applied cognitive psychology》2018,32(3):315-325
The autobiographical memory model of posttraumatic stress disorder (PTSD) argues that centralizing a traumatic event into one's life story is a maladaptive process associated with increased PTSD symptoms. Current measures of event centralization make no reference to whether individuals centralize the event in a positive or negative way. This study examined 400 undergraduate participants using a modified version of the Centrality of Events Scale composed of 2 factors measuring both positive and negative event centralization. Exploratory factor analysis confirmed the 2‐factor structure. Negative event centralization was associated with PTSD symptoms to a greater degree than was positive event centralization, and negative event centralization mediated the relationship between neuroticism and PTSD symptoms. Combined, these results suggest that the effect of event centralization is dependent on the valence with which the individual centralizes the event. The relationship shown between negative event centralization and PTSD symptoms supports the autobiographical memory model of PTSD. 相似文献

During military deployment, soldiers are confronted with both negative and positive events. What is remembered and how it affects an individual is influenced by not only the perceived emotion of the event, but also the emotional state of the individual. Here we examined the most negative and most positive deployment memories from a company of 337 soldiers who were deployed together to Afghanistan. We examined how the level of emotional distress of the soldiers and the valence of the memory were related to the emotional intensity, experience of reliving, rehearsal and coherence of the memories, and how the perceived impact of these memories changed over time. We found that soldiers with higher levels of post-traumatic stress disorder (PTSD) symptoms were more affected by both their negative and positive memories, compared with soldiers with lower levels of PTSD symptoms. Emotional intensity of the most negative memory increased over time in the group with highest levels of PTSD symptoms, but dropped in the other groups. The present study adds to the literature on emotion and autobiographical memory and how this relationship interacts with an individual’s present level of emotional distress and the passage of time. 相似文献
