    Background Little is known about the mechanisms explaining an increased perception of heart symptoms in congenital heart disease (ConHD). In the present study, it was suggested that a combination of high trait anxiety and disease history increases the perception of heart symptoms. Purpose It was tested whether false heart cues will result in an increased perception of heart symptoms in patients with ConHD and anxiety. Method Thirty-six patients with ConHD and 44 healthy controls performed two exercise tasks. During one of the exercise tasks, participants were exposed to a false heart cue consisting of false heart rate feedback (regular or irregular). Perceived heart symptoms were assessed and heart rate, arterial partial pressure of CO2, and respirator rate were monitored continuously. Results In line with the predictions, false heart rate feedback resulted in an increased perception of heart symptoms in high trait anxious patients with ConHD that could not be explained by acute heart dysfunction. However, unexpectedly, this effect was not observed immediately after the false heart rate feedback task but after a second exercise task without false feedback. Conclusion The results suggest that not the sole presence of ConHD but ConHD in combination with high trait anxiety results in a vulnerability to overperceive heart symptom

    The CHIP-Family study to improve the psychosocial wellbeing of young children with congenital heart disease and their families: design of a randomized controlled trial

    Background: Children with congenital heart disease (CHD) are at increased risk for behavioral, emotional, and cognitive problems. They often have reduced exercise capacity and participate less in sports, which is associated with a lower quality of life. Starting school may present more challenges for children with CHD and their families than for families with healthy children. Moreover, parents of children with CHD are at risk for psychosocial problems. Therefore, a family-centered psychosocial intervention for children with CHD when starting school is needed. Until now, the 'Congenital Heart Disease Intervention Program (CHIP) - School' is the only evidence-based intervention in this field. However, CHIP-School targeted parents only and resulted in non-significant, though positive, effects as to child psychosocial wellbeing. Hence, we expanded CHIP by adding a specific child module and including siblings, creating the CHIP-Family intervention. The CHIP-Family study aims to (1) test the effects of CHIP-Family on parental mental health and psychosocial wellbeing of CHD-children and to (2) identify baseline psychosocial and medical predictors for the e

    Consumers’ experiences of back pain in rural Western Australia: Access to information and services, and self-management behaviours.

    Background: Coordinated, interdisciplinary services, supported by self-management underpin effective management for chronic low back pain (CLBP). However, a combination of system, provider and consumer-based barriers exist which limit the implementation of such models into practice, particularly in rural areas where unique access issues exist. In order to improve health service delivery for consumers with CLBP, policymakers and service providers require a more in depth understanding of these issues. The objective of this qualitative study was to explore barriers experienced by consumers in rural settings in Western Australia (WA) to accessing information and services and implementing effective self-management behaviours for CLBP. Methods: Fourteen consumers with a history of CLBP from three rural sites in WA participated. Maximum variation sampling was employed to ensure a range of experiences were captured. An interviewer, blinded to quantitative pain history data, conducted semi-structured telephone interviews using a standardised schedule to explore individuals’ access to information and services for CLBP, and self-management behaviours. Interviews were digitally recorded and transcribed verbatim. Inductive analysis techniques were used to derive and refine key themes. Results: Five key themes were identified that affected individuals’ experiences of managing CLBP in a rural setting, including: 1) poor access to information and services in rural settings; 2) inadequate knowledge and skills among local practitioners; 3) feelings of isolation and frustration; 4) psychological burden associated with CLBP; and 5) competing lifestyle demands hindering effective self-management for CLBP.Conclusions: Consumers in rural WA experienced difficulties in knowing where to access relevant information for CLBP and expressed frustration with the lack of service delivery options to access interdisciplinary and specialist services for CLBP. Competing lifestyle demands such as work and family commitments were cited as key barriers to adopting regular self-management practices. Consumer expectations for improved health service coordination and a workforce skilled in pain management are relevant to future service planning, particularly in the contexts of workforce capacity, community health services, and enablers to effective service delivery in primary care

    Pain catastrophizing moderates the effects of pain-contingent task interruptions

    BACKGROUND: A prominent behavioural consequence of pain is the temporary suspension of current activities with intent to resume them later. Little is known about the effects of such pain-contingent task interruptions. This experiment examines the influence of pain-contingent interruptions on the amount of time spent performing a cognitive achievement task: We expected that people would spend more time on task when task performance was interrupted in response to pain (vs. no interruption), and that negative mood and pain catastrophizing would enhance this negative impact. METHODS: Healthy volunteers read behaviour descriptions until they felt they could form a good impression. Before task performance, participants underwent a negative or positive mood induction. During the task, all participants expected painful stimulation. Half of the participants in each mood induction group received an acute (electrocutaneous) pain stimulus, resulting in a 2-min break from the task. The other participants received no sensory stimulation during task performance and their performance was not interrupted. RESULTS: Results revealed no effect of mood on task performance (i.e., total number of descriptions read). There was, however, a significant interaction between task interruption and pain catastrophizing, indicating that participants with low levels of catastrophizing tended to read more descriptions when performance was interrupted than when not, whereas participants reporting relatively high levels of catastrophizing showed the reverse behavioural pattern. CONCLUSIONS: The impact of pain-contingent task interruptions was reversed in participants reporting relatively high levels of pain catastrophizing. Results are discussed with regard to interruption management in the context of chronic pain.status: publishe

    A content analysis of activity pacing in chronic pain: What are we measuring and why?

    No full text
    BACKGROUND: Activity pacing is a common intervention for patients with chronic pain. Over the past decade a number of instruments have been developed to measure this construct, but their comparative psychometric properties have not been examined. OBJECTIVE: To review the psychometric properties of existing measures of activity pacing, and provide suggestions for future research in this emerging area of pain research. METHODS: A narrative review of current measures of activity pacing followed by a discussion of the conceptual and psychometric challenges in this area. RESULTS: Although there is evidence supporting activity pacing as a unitary construct, important differences remain among the various measures in terms of their item content and assumptions. All existing activity pacing measures include items that assess activity regulation, but vary in their specific content. Most importantly, questionnaire items often reflect different purposes of pacing behaviors. DISCUSSION: Current measures of activity pacing are inadequate. New measures are needed that are based on specific theoretical models; these measures should also make the goal or intent of pacing behaviors explicit. Improvements in the assessment of activity pacing will likely lead to a better understanding of the pacing construct and the effects of pacing interventions.status: publishe
