The Communal Coping Model of pain catastrophizing proposes that pain catastrophizers enact pain behaviors in order to solicit support or empathy from their social environment. By this account, pain catastrophizers might be expected to engage in behavior aimed at maximizing the probability that their pain will be perceived by others in their social environment. To test this prediction, 40 undergraduates were videotaped during a cold pressor procedure. A separate sample of 20 (10 men, 10 women) undergraduates were asked to view the video sequences and infer the pain ratings of the cold pressor participants. Correlational analyses revealed that higher levels of pain catastrophizing of the cold pressor participants were associated with observer inferences of more intense pain, r=.39, p<.01. The relation between cold pressor participants' level of pain catastrophizing and observer inferences of pain intensity was mediated by the cold pressor participants' pain behavior. Although pain catastrophizing was associated with observers' inferences of more intense pain, cold pressor participants' level of pain catastrophizing was not associated with observers' accuracy in inferring self-reported pain. Implications of the findings for theory and clinical practice are addressed.
The purpose of the present research was to examine the influence of communication goals and physical demands on the expression of communicative (e.g., facial grimaces) and protective (e.g., guarding) pain behaviors. Participants with musculoskeletal conditions (N=50) were asked to lift a series of weights under two communication goal conditions. In one condition, participants were asked to estimate the weight of the object they lifted. In a second condition, participants were asked to rate their pain while lifting the same objects. The display of communicative pain behaviors varied as a function of the communication goal manipulation; participants displayed more communicative pain behavior when asked to rate their pain while lifting objects than when they estimated the weight of the object. Protective pain behaviors varied with the physical demands of the task, but not as a function of the communication goals manipulation. Pain ratings and self-reported disability were significantly correlated with protective pain behaviors but not with communicative pain behaviors. The results of this study support the functional distinctiveness of different forms of pain behavior. Findings are discussed in terms of evolutionary and learning theory models of pain behavior. Clinical implications of the findings are addressed.
This study shows that, the majority of elderly edentate individuals who have not experienced mandibular two-implant overdenture therapy are willing to pay the cost, particularly when payment can be made in monthly instalments.
Past research has shown that pain catastrophizing contributes to heightened pain experience. The hypothesis advanced in this study was that individuals who score high on measures of pain catastrophizing would also perceive more intense pain in others. The study also examined the role of pain behaviour as a determinant of the relation between catastrophizing and estimates of others' pain. To test the hypothesis, 60 undergraduates were asked to view videotapes of individuals taking part in a cold pressor procedure. Each individual in the videotapes was shown three times over the course of a 1min immersion such that the same individual was observed experiencing different levels of pain. Correlational analyses revealed a significant positive correlation between levels of pain catastrophizing and inferred pain intensity, r=.31, p<.01. Follow-up analyses indicated that catastrophizing was associated with a heightened propensity to rely on pain behaviour as a basis for drawing inferences about others' pain experience. Catastrophizing was associated with more accurate pain inferences on only one of three indices of inferential accuracy. The pattern of findings suggests that increasing reliance on pain behaviour as a means of inferring others' pain will not necessarily yield more accurate estimates. Discussion addresses the processes that might underlie the propensity to attend more to others' pain behaviour, and the clinical and interpersonal consequences of perceiving more pain in others.
Key Points Question What is the seroprevalence of SARS-CoV-2 antibodies in a convenience sample of children aged 2 to 17 years in Montreal, Canada, enrolled between October 2020 and March 2021? Findings In this cohort study of 1632 participants, the mean baseline seroprevalence of SARS-CoV-2 was 5.8%. Of the 95 participants who were seropositive for SARS-CoV-2 antibodies, 82% were not tested or tested negative, and all experienced either mild or no clinical symptoms. Meaning The findings suggest that there was more transmission occurring in children compared with what was being detected, although children experienced few or mild symptoms.
