Qinqin W, Guangming R. Processing of Painful Pictures in Individuals With High and Low Rejection Sensitivity: Evidence From Event-Related Potentials. Iperception 2019; 10:2041669519879722.

Abstract
An increasing number of studies have investigated the relation between the processing of painful stimuli and rejection. Little was known, however, about the impact of the rejection sensitivity (RS) on the processing of painful pictures. This study addressed this issue using high temporal resolution event-related potential techniques. Thirty high RS (20 women and 10 men who scored in the top 20th percentile of the Rejection Sensitivity Questionnaire scores) and 30 low RS (20 women and 10 men who scored in the bottom 20th percentile) volunteers participated in the experiment. All volunteers performed a discrimination task of painful pictures in which they were asked to judge whether target pictures were painful or not. Behaviorally, participants exhibited shorter reaction times for painful than nonpainful pictures. For the P100 component, low RS participants showed stronger brain activities for painful than nonpainful pictures, suggesting vigilance toward painful pictures. High RS participants, however, exhibited no P100 amplitude differences between painful and nonpainful pictures, indicating an analgesia phenomenon. Furthermore, we found that there were larger amplitudes in the late late positive complex component for painful compared with nonpainful pictures, regardless of participants' RS. This suggested a person's further assessment for painful pictures. In short, our findings demonstrated that the level of RS influenced the pain processing at a very early stage of processing.

Abstract
Purpose The way individuals attend to pain is known to have a considerable impact on the experience and chronification of pain. One method to assess the habitual “attention to pain” is the Pain Vigilance and Awareness Questionnaire (PVAQ). With the present study, we aimed to test the psychometric properties of the German version of the PVAQ across pain-free samples and across patients with acute and chronic pain. Method Two samples of pain-free individuals (student sample (N = 255)/non-student sample (N = 362)) and two clinical pain samples (acute pain patients (N = 105)/chronic pain patients (N = 36)) were included in this cross-sectional evaluation of the German PVAQ. Factor structure was assessed using exploratory and confirmatory factor analyses. Reliability was assessed using internal consistency (Cronbach’s alpha). Construct validity was tested by assessing correlations between PVAQ and theoretically related constructs. Results Exploratory factor analysis (non-student sample) and confirmatory factor analysis (student sample, acute pain patient sample) suggested that a two-factor solution best fitted our data (“attention to pain,” “attention to changes in pain”). Internal consistency ranged from acceptable to good in all four samples. As hypothesized, the PVAQ correlated significantly with theoretically related constructs in all four samples, suggesting good construct validity in pain-free individuals and in pain patients. Conclusion The German PVAQ shows good psychometric properties across samples of pain-free individuals and patients suffering from pain that are comparable to PVAQ versions of other languages. Thus, the German PVAQ seems to be a measure of pain vigilance equally valid as found in other countries.

Exploring healthcare assistants' role and experience in pain assessment and management for people with advanced dementia towards the end of life: a qualitative study. BMC Palliat Care 2017; 16:6. [PMID: 28103847 PMCID: PMC5247820 DOI: 10.1186/s12904-017-0184-1] [Citation(s) in RCA: 41] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2016] [Accepted: 01/10/2017] [Indexed: 01/08/2023] Open
Abstract
BACKGROUND Pain assessment and management are key aspects in the care of people with dementia approaching the end of life but become challenging when patient self-report is impaired or unavailable. Best practice recommends the use of observational pain assessments for these patients; however, difficulties have been documented with health professionals' use of these tools in the absence of additional collateral patient knowledge. No studies have explored the role, perspectives and experiences of healthcare assistants in pain assessment and management in dementia; this study provides insight into this important area. METHODS A qualitative approach was adopted, using key informant interviews with healthcare assistants caring for people with advanced dementia approaching the end of life in hospice, nursing home and acute care settings. Thematic analysis was the analytic approach taken to interpretation of interview data. Data were collected between June 2014 and September 2015. RESULTS Fourteen participants took part in the study. Participants' average length of caring experience was 15.4 years and most were female. Three key themes emerged: recognising pain, reporting pain, and upskilling. Participants were often the first to notice obvious causes of pain and to detect changes in patient norms which signified hidden causes of pain. Comprehensive knowledge of resident norms enabled participants to observe for behavioural and nonverbal indicators of pain and distinguish these from non-pain related behaviours. Pain reporting was heavily impacted by relationships with professional staff and the extent to which participants felt valued in their role. Positive relationships resulted in comprehensive pain reports; negative relationships led to perfunctory or ambiguous reporting. Participants emphasised a desire for further training and upskilling, including in the use and reporting of basic pain tools. CONCLUSIONS Healthcare assistants are frontline staff who have a key role in direct patient care, spending a considerable amount of time with patients in comparison to other health professionals. These staff are often first to notice changes in patients that may signify pain and to alert professional staff. However, to ensure the quality of these reports, further efforts must be made in reversing stigma attached to this role and in upskilling these members of the healthcare team.

Abstract
BACKGROUND Pain perception in others can be influenced by different contextual factors. In clinical settings, the repeated exposure to others' pain has been proposed as a factor that could explain underestimation of patients' pain by health care providers. Previous research supported this idea by showing that repeated exposure to persons in pain biases the subsequent willingness to impute pain in others. However, it remains unclear if the effect of repeated exposure on the detection of pain extends to deliberate pain estimation of stimuli presented for a longer period. METHOD Therefore, in a first experiment, healthy participants were either exposed to clips of facial expressions of intense pain or neutral expressions before estimating the intensity of other individuals' pain expressions. To test the specificity of this effect with regard to the pain content, a second study was conducted with healthy adults, which compared the effect of exposure to fear, pain and neutral videos on subsequent pain assessment in others. RESULTS Results from the first experiment indicated that repeated exposure to others' pain diminished the subsequent estimation of the intensity of pain in others. Results from the second experiment suggested that exposure to fear could bias pain estimation in a similar manner. However, the absence of difference in ratings between the exposure to fear and neutral groups warrants caution in the interpretation of these findings. CONCLUSION By demonstrating that repeated exposure to others' pain diminished subsequent pain estimation in others, this study adds relevant information on the factors that could contribute to pain underestimation in health care professionals. WHAT DOES THIS STUDY ADD?: Repeated exposure to facial expressions of intense pain not only biases pain detection, but also pain estimation in others. Prior exposure to facial expressions of pain compared to exposure to neutral ones leads to a reduced estimation of others' pain. This effect is not specific to pain as exposure to another negative emotion (fear) also biases subsequent pain estimation. These results support the interpretation that the underestimation of patients' pain by health care professionals could be related to repeated exposure to other's pain.

Abstract
Attentional bias to pain among family caregivers of patients with pain may enhance the detection of pain behaviors in patients. However, both relatively high and low levels of attentional bias may increase disagreement between patients and caregivers in reporting pain behaviors. This study aims to provide further evidence for the presence of attentional bias to pain among family caregivers, to examine the association between caregivers' attentional bias to pain and detecting pain behaviors, and test whether caregivers' attentional bias to pain is curvilinearly related to patient and caregiver disagreement in reporting pain behaviors. The sample consisted of 96 caregivers, 94 patients with chronic pain, and 42 control participants. Caregivers and controls completed a dot-probe task assessing attention to painful and happy stimuli. Both patients and caregivers completed a checklist assessing patients' pain behavior. Although caregivers did not respond faster to pain congruent than pain incongruent trials, caregiver responses were slower in pain incongruent trials compared with happy incongruent trials. Caregivers showed more bias toward pain faces than happy faces, whereas control participants showed more bias toward happy faces than pain faces. Importantly, caregivers' attentional bias to pain was significantly positively associated with reporting pain behaviors in patients above and beyond pain severity. It is reassuring that attentional bias to pain was not related to disagreement between patients and caregivers in reporting pain behaviors. In other words, attentional bias does not seem to cause overestimation of pain signals.

Abstract
BACKGROUND Hypervigilance to pain is the automatic prioritization of pain-related compared with other stimuli. The processing of threat information is influenced by negative contexts. Therefore, we intended to explore such context effects on hypervigilance to pain-cues, taking individual differences in self-reported vigilance to pain into consideration. METHODS In all, 110 healthy subjects viewed task-irrelevant emotional facial expressions (anger, happy, neutral, and pain) overlaid in half of the trials with a fine grid. The instructed task was to indicate the presence/absence of this grid. A threatening context was established by applying electrical stimuli slightly below pain-threshold. Using scores of Pain Vigilance and Awareness Questionnaire, the sample was divided into high vs low pain vigilant subjects. Reaction times and event-related brain potentials were recorded. RESULTS No distinct attentional processing of pain faces (based on the event-related brain potentials) was observed as a function of high levels of self-reported vigilance to pain and contextual threat induction. High pain vigilant subjects showed generally enhanced processing of emotional and neutral faces as indicated by parameters of early (early posterior negativity) and late (late positive complex) processing stages. This enhancement was abolished when electro-stimuli were presented. CONCLUSION Contextual threat does not enhance the attentional capture of pain-cues when they are presented concurrently with competing task demands. The study could, however, replicate a generally enhanced attentional processing of emotional cues in high pain vigilant subjects. This underpins that hypervigilance to pain is related to changes in emotional processing.
