Project description:Appraisals and emotional regulation play a central role in posttraumatic stress disorder (PTSD). Despite research demonstrating cultural differences in everyday appraisals and emotion regulation, little research has investigated the influence of culture on these processes in PTSD. This study examined cultural differences in the associations between appraisals, emotion regulation and PTSD symptoms using trauma survivors from an individualistic Western culture (Australia) and a collectivistic Asian culture (Malaysia). Trauma survivors (N = 228; 107 Australian with European cultural heritage, 121 Malaysian with Malay, Indian or Chinese cultural heritage) completed an on-line survey assessing PTSD (PTSD Checklist for the DSM-5 with Life Events Checklist), appraisals (trauma-related, fatalism, cultural beliefs about adversity) and emotion regulation (suppression, reappraisal, interpersonal). The Malaysian group reported significantly greater fatalism, cultural beliefs about adversity, suppression and interpersonal emotion regulation than the Australian group. Greater trauma-specific appraisals, greater suppression, fewer cultural beliefs about adversity, and less use of social skills to enhance positivity were generally associated with greater PTSD symptom severity, with little evidence of cultural group moderating these associations. Interdependent self-construal mediated the relationships between cultural adversity beliefs, enhanced positivity, reappraisal, perspective taking and PTSD symptoms. Independent self-construal mediated the relationships between fatalism and perspective taking and PTSD symptoms. Cultural group did not moderate these indirect effects. Interdependent self-construal mediated the associations between interpersonal regulation strategies of soothing and social modelling with PTSD symptoms for the Malaysian but not the Australian group. These findings demonstrate the importance of considering self-construal and culture in understanding factors associated with PTSD.

Project description:Previous research has shown that the habit of suppressing emotional expressions is associated with long-term, general reductions in social cognitive abilities and interpersonal adjustment. This may be because theoretically, habitual suppression requires the fixation of attention to the self instead of to others. The present research explored the association between the habitual tendency to suppress one's own emotions and accuracy in recognizing the emotions of others. Emotion recognition accuracy was tested across two tasks, a limited-channel task that presents limited emotional information and a multimodal full-channel task. We further explored cultural differences in this association given that expressive suppression may be normative for individuals of Asian descent due to cultural motivations toward social harmony and interdependence. Our findings revealed few cultural group differences. U.S.-born Asian Americans outperformed foreign-born Asian Americans and European Americans in limited-channel emotion recognition. However, the three groups did not differ in terms of interdependent self-construal, habitual emotion suppression, and full-channel emotion recognition ability. Interdependent self-construal was related to greater habitual suppression and emotion recognition accuracy in the full-channel task. Habitual emotion suppression was negatively related to limited-channel but not full-channel emotion recognition. There was no evidence of cultural differences in the link between habitual suppression and emotion recognition.

Project description:Background and objectivesCognitive reappraisal (CR) and emotional suppression (ES), two emotion regulation strategies, are disrupted in other substance use disorders but have not been studied in cocaine dependence.MethodsMethadone-maintained individuals with cocaine dependence (N = 72) completed assessment of CR, ES, cocaine use, and psychiatric symptoms.ResultsCR scores were associated with lower depression scores (r = -.29, p = .01), but not with cocaine abstinence during 8 weeks of treatment (r = .12, p = .29).Conclusions and scientific significanceCR appeared relevant to cocaine-dependent individuals' depression, but was not associated with abstinence or treatment outcome.

Project description:Amygdala dysregulation has been shown to be central to the pathophysiology of posttraumatic stress disorder (PTSD) representing a critical treatment target. Here, amygdala downregulation was targeted using real-time fMRI neurofeedback (rt-fMRI-nf) in patients with PTSD, allowing us to examine further the regulation of emotional states during symptom provocation. Patients (n = 10) completed three sessions of rt-fMRI-nf with the instruction to downregulate activation in the amygdala, while viewing personalized trauma words. Amygdala downregulation was assessed by contrasting (a) regulate trials, with (b) viewing trauma words and not attempting to regulate. Training was followed by one transfer run not involving neurofeedback. Generalized psychophysiological interaction (gPPI) and dynamic causal modeling (DCM) analyses were also computed to explore task-based functional connectivity and causal structure, respectively. It was found that PTSD patients were able to successfully downregulate both right and left amygdala activation, showing sustained effects within the transfer run. Increased activation in the dorsolateral and ventrolateral prefrontal cortex (PFC), regions related to emotion regulation, was observed during regulate as compared with view conditions. Importantly, activation in the PFC, rostral anterior cingulate cortex, and the insula, were negatively correlated to PTSD dissociative symptoms in the transfer run. Increased functional connectivity between the amygdala- and both the dorsolateral and dorsomedial PFC was found during regulate, as compared with view conditions during neurofeedback training. Finally, our DCM analysis exploring directional structure suggested that amygdala downregulation involves both top-down and bottom-up information flow with regard to observed PFC-amygdala connectivity. This is the first demonstration of successful downregulation of the amygdala using rt-fMRI-nf in PTSD, which was critically sustained in a subsequent transfer run without neurofeedback, and corresponded to increased connectivity with prefrontal regions involved in emotion regulation during the intervention.

Project description:The effects of current posttraumatic stress disorder (PTSD) interventions on emotion regulation are relatively unknown. Many conceptualize PTSD as a disorder of emotion dysregulation, and clinicians often fear that emotion regulation impairments will not change with stand-alone PTSD treatments, particularly for individuals with pre-existing emotion regulation difficulties. The present study examined changes in emotion regulation (expressive suppression, cognitive reappraisal, negative mood regulation) with prolonged exposure (PE) therapy or sertraline, specifically examining whether those with higher pre-existing emotion regulation difficulties improved over treatment on these indices. Individuals with chronic PTSD (N = 200) received 10 weeks of PE or sertraline and were followed through 6-month follow-up. Emotion regulation was assessed at pre- and post-treatment and at 3- and 6-month follow-up. Individuals with poorer initial emotion regulation showed greater improvement on all indices of emotion regulation, regardless of which treatment they received. Changes occurred during active treatment and were maintained over follow-up. These findings have both theoretical and clinical implications, arguing that emotion regulation is not impaired across all individuals with PTSD and that PE and sertraline effectively address emotion regulation difficulties.

Project description:ObjectivesAge shifts in emotion regulation may be rooted in beliefs about different strategies. We test whether there are age differences in the beliefs people hold about specific emotion regulation strategies derived from the process model of emotion regulation and whether profiles of emotion beliefs vary by age.MethodAn adult life-span sample (N = 557) sorted 13 emotion regulation strategies either by (a) how effective the strategies would be or (b) how likely they would be to use them, in 15 negative emotion-eliciting situations.ResultsYounger adults ranked attentional and cognitive distraction more effective than older adults, and preferred avoidance, distraction, and rumination more (and attentional deployment less) than middle-aged and older adults. Latent profile analysis on preferences identified three distinct strategy profiles: Classically adaptive regulators preferred a variety of strategies; situation modifiers showed strong preferences for changing situations; a small percentage of people preferred avoidance and rumination. Middle-aged and older adults were more likely than younger adults to be classically adaptive regulators (as opposed to situation modifiers or avoiders/ruminators).DiscussionThese findings provide insight into the reasons people of different ages may select and implement different emotion regulation strategies, which may influence their emotional well-being.

Project description:Problems with positive emotion are an important component of posttraumatic stress disorder (PTSD), with competing perspectives as to why. The global model suggests that people with PTSD experience a relatively permanent shift in their capacity for positive emotion regardless of context, whereas the context-specific model posits access to the full repertoire of positive emotion that only becomes reduced during exposure to trauma reminders. We tested the global versus context-specific models using ecological momentary assessment (EMA). Trauma-exposed adult community members (N = 80) with (n = 39) and without diagnosed PTSD completed 3 days of EMA (n = 2,158 observations). Participants with PTSD reported lower average momentary levels of positive emotion, B = -0.947, 95% CI [-1.35, -0.54], p < .001, and positive situations, B = -0.607, 95% CI [-1.16, -0.05], p = .032, and more thinking about trauma reminders, B = 0.360, 95% CI [0.21, 0.51], p < .001. There was no between-group difference in positive emotion reactivity (degree of positive emotion derived from positive situations), B = 0.03, 95% CI [-0.09, 0.14], p = .635. Increased thinking about trauma reminders predicted lower momentary levels of positive emotion, B = -0.55, 95% CI [-0.83, -0.26], p < .001, but not reactivity, B = 0.02, 95% CI [-0.35, 0.40], p = .906, irrespective of PTSD status. Findings supported the global model and were inconsistent with the context-specific model. This study helps clarify positive emotional functioning in trauma-exposed adults and highlights future directions to better understand problems with positive emotion in PTSD.

Project description:Emotion processing abnormalities and sleep pathology are central to the phenomenology of paediatric posttraumatic stress disorder, and sleep disturbance has been linked to the development, maintenance and severity of the disorder. Given emerging evidence indicating a role for sleep in emotional brain function, it has been proposed that dysfunctional processing of emotional experiences during sleep may play a significant role in affective disorders, including posttraumatic stress disorder. Here we sought to examine the relationship between sleep and emotion processing in typically developing youth, and youth with a diagnosis of posttraumatic stress disorder . We use high-density electroencephalogram to compare baseline sleep with sleep following performance on a task designed to assess both memory for and reactivity to negative and neutral imagery in 10 youths with posttraumatic stress disorder, and 10 age- and sex-matched non-traumatized typically developing youths. Subjective ratings of arousal to negative imagery (ΔArousal = post-sleep minus pre-sleep arousal ratings) remain unchanged in youth with posttraumatic stress disorder following sleep (mean increase 0.15, CI -0.28 to +0.58), but decreased in TD youth (mean decrease -1.0, 95% CI -1.44 to -0.58). ΔArousal, or affective habituation, was negatively correlated with global change in slow-wave activity power (ρ = -0.58, p = .008). When considered topographically, the correlation between Δslow-wave activity power and affective habituation was most significant in a frontal cluster of 27 electrodes (Spearman, ρ = -0.51, p = .021). Our results highlight the importance of slow-wave sleep for adaptive emotional processing in youth, and have implications for symptom persistence in paediatric posttraumatic stress disorder. Impairments in slow-wave activity may represent a modifiable risk factor in paediatric posttraumatic stress disorder.

Project description:Women are twice as likely as men to develop Posttraumatic Stress Disorder (PTSD). Abnormal acquisition of conditioned fear has been suggested as a mechanism for the development of PTSD. While some studies of healthy humans suggest that women are either no different or express less conditioned fear responses during conditioning relative to men, differences in the acquisition of conditioned fear between men and women diagnosed with PTSD has not been examined.Thirty-one participants (18 men; 13 women) with full or subsyndromal PTSD completed a fear conditioning task. Participants were shown computer-generated colored circles that were paired (CS+) or unpaired (CS-) with an aversive electrical stimulus and skin conductance levels were assessed throughout the task.Repeated measures ANOVA indicated a significant sex by stimulus interaction during acquisition. Women had greater differential conditioned skin conductance responses (CS + trials compared to CS- trials) than did men, suggesting greater acquisition of conditioned fear in women with PTSD.In contrast to studies of healthy individuals, we found enhanced acquisition of conditioned fear in women with PTSD. Greater fear conditioning in women may either be a pre-existing vulnerability trait or an acquired phenomenon that emerges in a sex-dependent manner after the development of PTSD. Characterizing the underlying mechanisms of these differences is needed to clarify sex-related differences in the pathophysiology of PTSD.

Project description:Previous research has shown that individuals with substance use disorder (SUD) and posttraumatic stress disorder (PTSD) have emotional processing difficulties. However, no studies have specifically investigated the role of emotional processing in those with co-morbid SUD-PTSD. This study investigated whether there are more emotional processing abnormalities among patients with SUD-PTSD, than those with either a single diagnosis of PTSD or SUD. Emotional processing was assessed in three groups [1) SUD (without PTSD); 2) PTSD (without SUD); and 3) co-morbid SUD-PTSD] using the Emotional Processing Scale (EPS-25) and the International Affective Picture System (IAPS). Each of the three groups reported evidence of emotional processing dysfunction relative to the normal population. Within the SUD-PTSD group there was significant evidence that the additional impact of trauma increased emotional processing dysfunction but less evidence to suggest that substance use increased emotional processing dysfunction further. These findings call into question current United Kingdom guidelines for the treatment of co-morbid SUD-PTSD, which recommend that the drug or alcohol problem should be treated first.
