The Impact of Adolescent Chronic Pain on Functioning: Disentangling the Complex Role of Anxiety

A number of adolescents with chronic pain have clinically significant disability across physical, social, and academic activities, and pain severity only explains a portion of the variance in functioning. Thus, it is important to identify therapeutic options to improve adolescents’ functioning. In contrast to studies with adults with chronic pain, research in pediatric pain has not consistently found anxiety to be a good predictor of pain-related disability. The present study evaluated pain, anxiety, and functioning in 222 adolescents with chronic pain. Results indicated that pain was consistently and linearly related to disability across measures of physical and social functioning, school attendance, and physician visits. The relation between anxiety and functioning was complex; increased anxiety was related to poorer physical and social functioning and was related to fewer physician visits, although it was not associated with school attendance. Additional analyses revealed that anxiety serves to moderate the relation between pain and functioning. Specifically, at high anxiety, pain was not related to functioning, but at low anxiety pain consistently predicted disability. In other words, highly anxious adolescents were functioning poorly regardless of the level of pain. The moderating role of anxiety highlights a number of research and clinical possibilities to explore with adolescents with chronic pain-related disability. Data suggest that high anxiety is associated with poor functioning irrespective of pain intensity. At low anxiety, higher pain predicted greater disability. Anxiety is important to assess when investigating potential reasons for pain-related disability

Brain structural changes during juvenile fibromyalgia: relationships with pain, fatigue and functional disability

Objective: Juvenile fibromyalgia (FM) is a prevalent chronic pain condition affecting children and adolescents worldwide during a critical period of brain development. To date, no published studies have addressed the pathophysiology of juvenile FM. This study was undertaken to characterize gray matter volume (GMV) alterations in juvenile FM patients for the first time, and to investigate their functional and clinical relevance. Methods: Thirty-four female adolescents with juvenile FM and 38 healthy adolescents underwent a structural magnetic resonance imaging examination and completed questionnaires assessing core juvenile FM symptoms. Using voxel-based morphometry, we assessed between-group GMV differences and associations between GMV and functional disability, fatigue, and pain interference in juvenile FM. We also studied whether validated brain patterns predicting pain, cognitive control, or negative emotion were amplified/attenuated in juvenile FM patients and whether structural alterations reported in adult FM were replicated in adolescents with juvenile FM. Results: Compared to controls, juvenile FM patients showed GMV reductions in the anterior midcingulate cortex (aMCC) region (family-wise error corrected P [PFWE-corr ] = 0.04; estimated with threshold-free cluster enhancement [TFCE]; n = 72) associated with pain. Within the juvenile FM group, patients reporting higher functional disability had larger GMV in inferior frontal regions (PFWE-corr = 0.006; TFCE estimated; n = 34) linked to affective, self-referential, and language-related processes. Last, GMV reductions in juvenile FM showed partial overlap with findings in adult FM, specifically for the anterior/posterior cingulate cortices (P = 0.02 and P = 0.03, respectively; n = 72). Conclusion: Pain-related aMCC reductions may be a structural hallmark of juvenile FM, whereas alterations in regions involved in emotional, self-referential, and language-related processes may predict disease impact on patients' well-being. The partial overlap between juvenile and adult FM findings strengthens the importance of early symptom identification and intervention to prevent the transition to adult forms of the disease

A qualitative study of risk and resilience in young adult women with a history of juvenile-onset fibromyalgia

Background: Juvenile-onset Fibromyalgia (JFM) is a chronic pain condition characterized by widespread musculoskeletal pain, fatigue, sleep difficulties, mood concerns, and other associated symptoms. Although diagnosed in childhood, JFM often persists into adulthood can result in continued physical, social, and psychological impairment. The purpose of this qualitative study was to identify themes of risk and resilience for long-term outcomes among young adults diagnosed with JFM in childhood. Methods: The sample included 13 young adults (ages 26-34) who had been diagnosed with JFM in adolescence. Focus groups were used to elicit qualitative information about living with JFM and perceived challenges and buffering factors impacting their adjustment. Results: The majority of participants (80%, N = 12) continued to meet criteria for fibromyalgia (FM). An iterative, thematic analysis revealed themes of resilience (e.g., greater acceptance, re-setting expectations, active coping, addressing mental health) and risk (e.g., lack of information, stigma, isolation, negative healthcare experiences). Conclusion: Results suggest the need for longer follow-up of youth with JFM as they transition to adulthood with multidisciplinary care and more attention to education about JFM and associated symptoms such as fatigue, as well as ongoing support for coping and mental health needs. A holistic approach to care during the transition years could be beneficial to minimize impact of JFM on long-term functioning

The role of pain-related anxiety in adolescents' disability and social impairment: ALSPAC data

Background  Anxiety, in particular pain-related anxiety, plays an important role in explaining the severity of pain complaints and pain-related disability in both adults and children with chronic pain. The fear-avoidance model (FAM) describes how pain-related anxiety plays a critical role in the maintenance of pain-avoidance behaviour, which in turn influences pain-related disability. However, the FAM does not take into account broader aspects of adolescence, such as social functioning, which could be negatively impacted by anxiety. In addition, most studies examining the role of anxiety in pain have used small convenience or clinical samples. By using a large UK epidemiological database, this study investigated the associations between pain-related anxiety, disability and judgements of social impairment.  Methods  Participants (n = 856) with recurrent pain were selected from a larger epidemiological study (Avon Longitudinal Study of Parents and Children) of adolescents attending a research clinic at the age of 17 (n = 5170). Adolescents completed a self-report questionnaire on pain-related anxiety, disability and perceived social impairment.  Results  High levels of pain-related anxiety were associated with more disability. In girls, higher levels of pain-related anxiety were also related to the self-perception of greater impairment in social functioning compared with their peers.  Conclusions  Pain-related anxiety was associated with greater pain-related disability and impaired social functioning. Social functioning should be explored as an integral part of fear-avoidance models of adolescent chronic pain. © 2014 European Pain Federation-EFIC®

Patient experiences of anxiety, depression and acute pain after surgery: a longitudinal perspective

This study sought to explore the impact of the psychological variables anxiety and depression, on pain experience over time following surgery. Eighty-five women having major gynaecological surgery were assessed for anxiety, depression and pain after surgery. To gain further understanding, 37 patients participated in a semi-structured taped telephone interview 4–6 weeks post-operatively. Pre-operative anxiety was found to be predictive of post-operative anxiety on Day 2, with patients who experienced high levels of anxiety before surgery continuing to feel anxious afterwards. By Day 4 both anxiety and depression scores increased as pain increased and one-third of the sample experienced levels of anxiety in psychiatric proportions whilst under one-third experienced similar levels of depression. These findings have significant implications for the provision of acute pain management after surgery. Future research and those managing acute pain services need to consider the multidimensional effect of acute pain and the interface between primary and secondary care

Peer mentorship to promote effective pain management in adolescents: study protocol for a randomised controlled trial

<p>Abstract</p> <p>Background</p> <p>This protocol is for a study of a new program to improve outcomes in children suffering from chronic pain disorders, such as fibromyalgia, recurrent headache, or recurrent abdominal pain. Although teaching active pain self-management skills through cognitive-behavioral therapy (CBT) or a complementary program such as hypnotherapy or yoga has been shown to improve pain and functioning, children with low expectations of skill-building programs may lack motivation to comply with therapists' recommendations. This study will develop and test a new manualized peer-mentorship program which will provide modeling and reinforcement by peers to other adolescents with chronic pain (the mentored participants). The mentorship program will encourage mentored participants to engage in therapies that promote the learning of pain self-management skills and to support the mentored participants' practice of these skills. The study will examine the feasibility of this intervention for both mentors and mentored participants, and will assess the preliminary effectiveness of this program on mentored participants' pain and functional disability.</p> <p>Methods</p> <p>This protocol will recruit adolescents ages 12-17 with chronic pain and randomly assign them to either peer mentorship or a treatment-as-usual control group. Mentored participants will be matched with peer mentors of similar age (ages 14-18) who have actively participated in various treatment modalities through the UCLA Pediatric Pain Program and have learned to function successfully with a chronic pain disorder. The mentors will present information to mentored participants in a supervised and monitored telephone interaction for 2 months to encourage participation in skill-building programs. The control group will receive usual care but without the mentorship intervention. Mentored and control subjects' pain and functioning will be assessed at 2 months (end of intervention for mentored participants) and at 4 month follow-up to see if improvements persist. Measures of treatment adherence, pain, disability, and anxiety and depression will be assessed throughout study participation. Qualitative interviews for mentors, mentored participants, and control subjects will also be administered.</p> <p>Trial registration</p> <p>ClinicalTrials.gov <a href="http://www.clinicaltrials.gov/ct2/show/NCT01118988">NCT01118988</a>.</p
