Objectives: This study aimed to analyze the associations among depressive/anxiety and pain symptoms in patients diagnosed with chronic pain. Methods: Four hundred and fifty-four inpatients who were consecutively admitted in a multimodal 3-weeks treatment in a tertiary psychosomatic university clinic completed 25 items from the Brief Pain Inventory and the Hospital Anxiety and Depression Scale at baseline and after treatment termination.Associations among symptoms were explored by network analyses using the graphical least absolute shrinkage and selection operator to estimate their partial correlations, while Extended Bayesian Information Criterion was used to select the best network solution for the data. We explored symptoms' centrality and expected influence within the network as well as the minimum spanning tree for the network. Results: Besides expected associations within depressive/anxiety and pain symptoms, the estimated network showed several local associations between depressive and pain interference symptoms. The lacks of being cheerful and of laughing are two of the depressive symptoms that showed the greatest associations with pain interference and a strong centrality within the network. Sleep problems were both associated with anxiety/depressive symptoms and pain intensity symptoms. Although at posttreatment, most of the symptoms showed a significant decrease, the strength of the associations between the symptoms within the network were significantly higher than at baseline. Discussion: The results support focusing psychosocial interventions in chronic pain treatment not only on reducing pain, anxiety and sleep symptoms but also on enhancing positive affect. Future research is needed to replicate these findings using repeated withinperson measures designs.
Adopting the perspective of another person is an important aspect of social cognition and has been shown to depend on multisensory signals from one’s own body. Recent work suggests that interoceptive signals not only contribute to own-body perception and self-consciousness, but also to empathy. Here we investigated if social cognition – in particular adopting the perspective of another person – can be altered by a systematic manipulation of interoceptive cues and further, if this effect depends on empathic ability. The own-body transformation task (OBT) – wherein participants are instructed to imagine taking the perspective and position of a virtual body presented on a computer screen – offers an effective way to measure reaction time differences linked to the mental effort of taking an other’s perspective. Here, we adapted the OBT with the flashing of a silhouette surrounding the virtual body, either synchronously or asynchronously with the timing of participants’ heartbeats. We evaluated the impact of this cardio-visual synchrony on reaction times and accuracy rates in the OBT. Empathy was assessed with the empathy quotient (EQ) questionnaire. Based on previous work using the cardio-visual paradigm, we predicted that synchronous (vs. asynchronous) cardio-visual stimulation would increase self-identification with the virtual body and facilitate participants’ ability to adopt the virtual body’s perspective, thereby enhancing performance on the task, particularly in participants with higher empathy scores. We report that participants with high empathy showed significantly better performance during the OBT task during synchronous versus asynchronous cardio-visual stimulation. Moreover, we found a significant positive correlation between empathic ability and the synchrony effect (the difference in reaction times between the asynchronous and synchronous conditions). We conclude that synchronous cardio-visual stimulation between the participant’s body and a virtual body during an OBT task makes it easier to adopt the virtual body’s perspective, presumably based on multisensory integration processes. However, this effect depended on empathic ability, suggesting that empathy, interoception and social perspective taking are inherently linked.
Introduction:Recent recommendations for the treatment of chronic pain patients during the coronavirus disease 2019 (COVID-19) pandemic suggest using telemedicine instead of in-person consultations. Knowing whether patients with chronic pain are receptive to the use of telemedicine during a pandemic might improve tailored care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
