Construct Validity and Measurement Invariance of the Difficulties in Emotion Regulation Scale - Short Form (DERS-SF): Further Evidence From Community and Student Samples.

The current study aimed to evaluate the psychometric properties of the Difficulties in Emotion Regulation Scale-Short Form (DERS-SF) in Iran, including testing its measurement invariance across sexes, as well as community and student populations. Two samples were recruited: a community sample of 583 participants (58.7% female; Mage = 33.55) and a university student sample of 409 participants (67.2% female; Mage = 24.48). Besides the DERS-SF, participants completed a battery of instruments online, measuring mentalizing capacity and borderline personality features. Confirmatory factor analyses supported the tenability of the five-factor model, excluding the awareness subscale. Except for the awareness subscale, acceptable to excellent internal consistencies were found for the DERS-SF and its subscales. The awareness-excluded DERS-SF was significantly and strongly associated with relevant constructs (|rs| = .49 to .59). This study also found evidence for configural, metric, and scalar invariance of the DERS-SF across sexes and community and student populations. Our findings extended the evidence for the validity and reliability of the DERS-SF and its awareness-excluded version by administering it in Iranian samples and supporting its cross-cultural applicability.

Selective attention to pain and empathy: Studying frequent blood donors.

INTRODUCTION: Empathy is an interpersonal experience that enables understanding of other's emotions and can lead to altruistic behavior such as blood donation. Cognitive theories of empathy refer to selective attention as one of its cognitive dimensions. The current study examined if individuals who engage in altruistic behavior are characterized by a distinct pattern of selective attention to observation of pain in others. METHODS: We recruited 50 volunteer blood donors. Half (n = 25) of the volunteers donated for a self-declared altruistic reason, and the other half of the volunteers donated blood for a health-related reason. We assessed the individuals' self-reported empathy with the Interpersonal Reactivity Index (IRI). We then measured the individuals' selective attention toward faces expressing pain in a pictorial dot-probe task. RESULTS: Consistent with the proposed hypothesis, participants who donated blood out of altruism reported significantly higher empathic concern on the IRI than those who donated blood for a health-related reason. The altruistic donors also showed significantly greater selective attention toward facial expressions of pain. Moreover, among all donors, self-report empathic concern on the IRI was significantly correlated with greater selective attention toward faces expressing pain. DISCUSSION: These findings suggest that altruistic individuals not only show higher levels of empathy, but also attend more to the pain of others. Limitations, implications, and suggestions for future research are discussed.

Eating disorder-specific rumination moderates the association between attentional bias to high-calorie foods and eating disorder symptoms: Evidence from a reliable free-viewing eye-tracking task.

Cognitive theories of eating disorders implicate Attentional Bias (AB) towards food-related information in the development and maintenance of eating disorders. Empirical evidence for this proposal, however, has been inconsistent, and the measures used to examine AB to food-related stimuli typically showed poor reliability. The aim of the current study was twofold. Firstly, we aimed to examine the psychometric properties of a newly devised eye-tracking task for the assessment of AB in the context of eating disorders. Secondly, we examined the role of Eating Disorder-specific (ED-specific) rumination as a potential moderator of the association between attentional bias to food images and eating disorder symptoms. One hundred and three female students were recruited and completed an eye-tracking task comprising 21 matrices that each contained 8 low-calorie and 8 high-calorie food images. Each matrix was presented for 6 s. First fixation location, first fixation latency, and total dwell time were assessed for low and high-calorie food images and the dwell-time based AB measure showed good reliability based on Cronbach's alpha, McDonald's Omega, and split-half method. In addition, the results revealed that the ED-specific rumination plays the hypothesized moderating role. Specifically, while participants with high levels of ED-specific rumination exhibited a positive association between AB to high-calorie foods and eating disorder symptoms, this association was not present among participants with lower levels of ED-specific rumination. The employed free-viewing task seems a reliable measure of AB to food-related stimuli, and the moderation analysis emphasizes the critical role of ED-specific rumination for eating disorder symptoms. Implications, limitations, and directions for future research are discussed.

Suppression May Improve Adaptation to Worry When Facing Uncertainty: Studying COVID-19 Pandemic.

The COVID-19 pandemic has been associated with increased uncertainty, fear and worry in everyone's life. The effect of changes in daily life has been studied widely, but we do not know how emotion-regulation strategies influence adaptation to a new situation to help them overcome worry in the face of uncertainty. Here, 1,064 self-selected Farsi speaking participants completed an online battery of questionnaires that measured fear of virus and illness, worry, intolerance of uncertainty, and emotion regulation (two subscales: reappraisal, suppression). We also documented the number of daily COVID-19 cases and deaths due to COVID-19 on the day in which participants completed the questionnaire. Our findings suggest a correlation between contamination fear and the number of daily-confirmed cases (r = 0.11), and the number of reported deaths due to COVID-19 (r = 0.09). Worry mediated the relationship between intolerance of uncertainty and fear of virus and illness (b = 0.16, 0.1141 < CI < 0.2113). In addition, suppression moderated the relationship between intolerance of uncertainty and worry (p < 0.01). Our results suggest that suppression (at least in the short term) can be an adaptive response to the worry associated with uncertainty. Suppression can reduce worry, which in turn can decrease fear of contamination and improve adaptation to social distancing requirements. Although, the observed correlations were significant, but considering the sample size, they are not strong, and they should be interpreted cautiously.

Attentional control moderates the relationship between social anxiety and selective attentional responding to negative social information: evidence from objective measures of attentional processes.

Cognitive theories of social anxiety implicate greater attention to negative social information in the development and maintenance of heightened social anxiety. Empirical evidence for this proposal, however, has been inconsistent. The aim of the current study was to examine the role of attentional control, which is one's ability to deploy attention to goal-relevant information as a potential moderator of the association between selective attentional responding to negative social information and social anxiety. Eighty-nine adults were recruited through Mechanical Turk platform and completed the Social Interaction Anxiety Scale as well as a novel paradigm designed to measure selective attentional responding to negative social information (angry faces) and attentional control. Attentional control was operationalised as the capacity to direct attention to the specified target stimuli. The results supported the hypothesis that attentional control plays this moderating role. Specifically, while participants with low levels of attentional control exhibited a positive association between social anxiety and selective attentional responding to negative social information, this association was eliminated among participants with high levels of attentional control. This finding may explain the heterogeneity of research findings in this area. Implications, limitations and directions for future research are discussed.

Time course of attentional bias to painful facial expressions and the moderating role of attentional control: an eye-tracking study.

INTRODUCTION: This study investigated the time course of attention to pain and examined the moderating effect of attentional control in the relationship between pain catastrophizing and attentional bias in chronic pain patients. METHODS: A total of 28 patients with chronic pain and 29 pain-free individuals observed pictures of pain, happy and neutral facial expressions while their gaze behaviour was recorded. Pain intensity and duration, anxiety, depression, stress, attentional control and pain catastrophizing were assessed by questionnaires. RESULTS: In all subjects, the pattern of attention for pain faces was characterized by initial vigilance, followed by avoidance. No significant difference was found between the two groups in terms of orientation towards the stimuli, the duration of first fixation, the average duration of fixation or number of fixations on the pain stimuli. Attentional control moderated the relationship between catastrophizing and overall dwell time for happy faces in pain patients, indicating that those with high attentional control and high catastrophizing focused more on happy faces, whereas the reverse was true for those with low attentional control. CONCLUSION: This study supported the vigilance-avoidance pattern of attention to painful facial expressions and a moderation effect of attentional control in the association between pain catastrophizing and attentional bias to happy faces among pain patients.

Attentional control moderates the relationship between pain catastrophizing and selective attention to pain faces on the antisaccade task.

Cognitive models of chronic pain emphasize the critical role of pain catastrophizing in attentional bias to pain-related stimuli. The aim of this study was (a) to investigate the relationship between pain catastrophizing and the ability to inhibit selective attention to pain-related faces (attentional bias); and (b) to determine whether attentional control moderated this relationship. One hundred and ten pain-free participants completed the anti-saccade task with dynamic facial expressions, specifically painful, angry, happy, and neutral facial expressions and questionnaires including a measure of pain catastrophizing. As predicted, participants with high pain catastrophizing had significantly higher error rates for antisaccade trials with pain faces relative to other facial expressions, indicating a difficulty disinhibiting attention towards painful faces. In moderation analyses, data showed that attentional control moderated the relationship between attentional bias to pain faces and pain catastrophizing. Post-hoc analyses demonstrated that it was shifting attention (not focusing) that accounted for this effect. Only for those with high self-reported ability to shift attention was there a significant relationship between catastrophizing and attentional bias to pain. These findings confirm that attentional control is necessary for an association between attentional bias and catastrophizing to be observed, which may explain the lack of relationships between attentional bias and individual characteristics, such as catastrophizing, in prior research.

Attentional bias and its temporal dynamics among war veterans suffering from chronic pain: Investigating the contribution of post-traumatic stress symptoms.

BACKGROUND: Cognitive models propose that attentional dysregulation, including an attentional bias towards threat, is one of the factors through which chronic pain and post-traumatic stress symptoms (PTSS) maintain and exacerbate one another. The current investigation assessed the attentional bias for painful facial expressions and its relationship with PTSS, using both traditional and variability-based attentional bias measures, among veterans with chronic pain and PTSS and controls. METHOD: Fifty-four veterans with chronic pain and 30 age/education-matched controls participated in this investigation. Participants completed a self-report measure of PTSS and a modified version of the dot-probe task with painful, happy, and neutral facial expressions. Attention was assessed using both traditional and variability-based reaction time measures of attentional bias. RESULTS: Veterans directed attention away from painful facial expressions (i.e., avoidance) relative to both the control group (between-subject effect) and relative to neutral faces (within-subject effect). Veterans also showed significantly elevated attentional bias variability for both happy and painful facial expressions compared to controls. Attentional bias variability for happy and painful facial expressions was correlated with PTSS among all participants. CONCLUSION: Veterans with chronic pain and PTSS avoided pain-related stimuli and displayed an overall attentional dysregulation for emotional facial expressions. Avoidance of pain cues may be a coping strategy that these individuals develop under stressful conditions. Implications, limitations, and directions for future research are discussed.

Observers' impression of the person in pain influences their pain estimation and tendency to help.

BACKGROUND: Estimation of a patient's pain may have a considerable impact on the level of care that patient receives. Many studies have shown that contextual factors may influence an observer's pain estimation. Here, we investigate the effect of an observer's impression of a person in pain and justification of his/her pain on the observer's pain estimation, tendency to help and perceived empathy. METHODS: Thirty healthy individuals (half females) read scenarios aimed to manipulate the reader's impression of characters who ultimately were fired from their work (four positive characters and four negative; half females). Then they observed 1-s videos of four levels of pain expression (neutral, mild, moderate, strong) in those characters during an examination. Subsequently, they rated pain estimation, tendency to help and perceived empathy. Afterwards, they rated their likability of characters and how just they find the end of story. RESULTS: People rated pain in positive characters higher than the pain in negative characters. They also expressed more tendency to help and a higher level of perceived empathy towards positive characters than negative characters. For the highest level of pain in positive characters, perceived injustice towards that person was the best predictor of the observer's pain estimation, tendency to help and perceived empathy. For negative characters, dislikeability was the best predictor of tendency to help and perceived empathy. Justification of their pain was a predictor of pain estimation and tendency to help. CONCLUSION: Observers used different information to evaluate pain in positive and negative individuals. SIGNIFICANCE: Observers' estimation of pain, perceived empathy and tendency to help biases by their understanding of the characteristics of the person in pain. In clinical settings, these biases may influence the quality of care and well-being of patients. Understanding the underlying mechanisms of these biases can help us improve the quality of care and control the effect of prejudices on pain assessment.

Anxiety Sensitivity Dimensions and Generalized Anxiety Severity: The Mediating Role of Experiential Avoidance and Repetitive Negative Thinking .

Objective: Generalized anxiety disorder is one of the most common anxiety disorders in the general population. Several studies suggest that anxiety sensitivity is a vulnerability factor in generalized anxiety severity. However, some other studies suggest that negative repetitive thinking and experiential avoidance as response factors can explain this relationship. Therefore, this study aimed to investigate the mediating role of experiential avoidance and negative repetitive thinking in the relationship between anxiety sensitivity and generalized anxiety severity. Method: This was a cross-sectional and correlational study. A sample of 475 university students was selected through stratified sampling method. The participants completed Anxiety Sensitivity Inventory-3, Acceptance and Action Questionnaire-II, Perseverative Thinking Questionnaire, and Generalized Anxiety Disorder 7-item Scale. Data were analyzed by Pearson correlation, multiple regression analysis and path analysis. Results: The results revealed a positive relationship between anxiety sensitivity, particularly cognitive anxiety sensitivity, experiential avoidance, repetitive thinking and generalized anxiety severity. In addition, findings showed that repetitive thinking, but not experiential avoidance, fully mediated the relationship between cognitive anxiety sensitivity and generalized anxiety severity. α Level was p<0.005. Conclusion: Consistent with the trans-diagnostic hypothesis, anxiety sensitivity predicts generalized anxiety severity, but its effect is due to the generating repetitive negative thought. .
