Depression and functional disability in chronic pediatric pain.

ObjectivesThe primary aim of this study was to describe pain characteristics, coping strategies, depression, and functional disability in children and adolescents with chronic pain and to examine potential factors that are associated with functional disability in a pediatric pain population. The secondary aim of this study was to compare functional disability in two chronic pain conditions: localized musculoskeletal pain and chronic daily headaches. SubjectsThe participants in this study were 73 pediatric pain patients with a variety of chronic pain conditions. Subjects in the second part of the study were a subset of patients (N = 44) from the pain clinic sample with chronic localized musculoskeletal pain and a subset of patients (N = 38) from the headache center of the same hospital who had chronic daily headaches. DesignPatients completed self-report measures of pain intensity, depression, coping strategies, coping efficacy, and functional disability. ResultsResults indicated that chronic pain had a substantial impact on the childrens lives and that depression was strongly associated with functional disability. Maladaptive coping was correlated with depression and disability; however, maladaptive coping was not independently associated with functional disability. A comparison between the two groups found significant differences in pain intensity and functional disability. The localized musculoskeletal pain group reported higher levels of disability and more difficulty coping than the chronic daily headache group. ConclusionsThe implications for treatment of chronic pain in children are discussed with an emphasis on greater attention to developmental issues and their relation to coping, emotional functioning, and disability in pediatric pain. Further research examining differences in coping and disability between different pediatric pain groups is also warranted.

Effects of spouse-assisted coping skills training and exercise training in patients with osteoarthritic knee pain: a randomized controlled study

&NA; This study tested the separate and combined effects of spouse‐assisted pain coping skills training (SA‐CST) and exercise training (ET) in a sample of patients having persistent osteoarthritic knee pain. Seventy‐two married osteoarthritis (OA) patients with persistent knee pain and their spouses were randomly assigned to: SA‐CST alone, SA‐CST plus ET, ET alone, or standard care (SC). Patients in SA‐CST alone, together with their spouses, attended 12 weekly, 2‐h group sessions for training in pain coping and couples skills. Patients in SA‐CST+ET received spouse‐assisted coping skills training and attended 12‐weeks supervised ET. Patients in the ET alone condition received just an exercise program. Data analyses revealed: (1) physical fitness and strength: the SA‐CST+ET and ET alone groups had significant improvements in physical fitness compared to SA‐CST alone and patients in SA‐CST+ET and ET alone had significant improvements in leg flexion and extension compared to SA‐CST alone and SC, (2) pain coping: patients in SA‐CST+ET and SA‐CST alone groups had significant improvements in coping attempts compared to ET alone or SC and spouses in SA‐CST+ET rated their partners as showing significant improvements in coping attempts compared to ET alone or SC, and (3) self‐efficacy: patients in SA‐CST+ET reported significant improvements in self‐efficacy and their spouses rated them as showing significant improvements in self‐efficacy compared to ET alone or SC. Patients receiving SA‐CST+ET who showed increased self‐efficacy were more likely to have improvements in psychological disability. An intervention that combines spouse‐assisted coping skills training and exercise training can improve physical fitness, strength, pain coping, and self‐efficacy in patients suffering from pain due to osteoarthritis.

Clinical utility and validity of the Functional Disability Inventory among a multicenter sample of youth with chronic pain.

&NA; The Functional Disability Inventory (FDI) is a well‐established and commonly used measure of physical functioning and disability in youth with chronic pain. Further validation of the measure has been called for, in particular, examination of the clinical utility and factor structure of the measure. To address this need, we utilized a large multicenter dataset of pediatric patients with chronic pain who had completed the FDI and other measures assessing pain and emotional functioning. Clinical reference points to allow for interpretation of raw scores were developed to enhance clinical utility of the measure, and exploratory factor analysis was performed to examine its factor structure. Participants included 1300 youth ages 8 to 18 years (mean = 14.2 years; 76% female) with chronic pain. Examination of the distribution of FDI scores and validation with measures of depressive symptoms and pain intensity yielded 3 distinct categories of disability: No/Minimal Disability, Moderate Disability, and Severe Disability. Factor analysis of FDI scores revealed a 2‐factor solution representing vigorous Physical Activities and non‐physically strenuous Daily Activities. The 3‐level classification system and factor structure were further explored via comparison across the 4 most commonly encountered pain conditions in clinical settings (head, back, abdominal, and widespread pain). Our findings provide important new information regarding the clinical utility and validity of the FDI. This will greatly enhance the interpretability of scores for research and clinical use in a wide range of pediatric pain conditions. In particular, these findings will facilitate use of the FDI as an outcome measure in future clinical trials. Clinical reference points and a preliminary factor structure for the Functional Disability Inventory (FDI) increase the clinical and research utility of the measure.

Cognitive Behavioral Therapy Plus Amitriptyline for Chronic Migraine in Children and Adolescents A Randomized Clinical Trial

IMPORTANCE Early, safe, effective, and durable evidence-based interventions for children and adolescents with chronic migraine do not exist. OBJECTIVE To determine the benefits of cognitive behavioral therapy (CBT) when combined with amitriptyline vs headache education plus amitriptyline. DESIGN, SETTING, AND PARTICIPANTS A randomized clinical trial of 135 youth (79% female) aged 10 to 17 years diagnosed with chronic migraine (≥15 days with headache/month) and a Pediatric Migraine Disability Assessment Score (PedMIDAS) greater than 20 points were assigned to the CBT plus amitriptyline group (n = 64) or the headache education plus amitriptyline group (n = 71). The study was conducted in the Headache Center at Cincinnati Childrens Hospital between October 2006 and September 2012; 129 completed 20-week follow-up and 124 completed 12-month follow-up. INTERVENTIONS Ten CBT vs 10 headache education sessions involving equivalent time and therapist attention. Each group received 1 mg/kg/d of amitriptyline and a 20-week end point visit. In addition, follow-up visits were conducted at 3, 6, 9, and 12 months. MAIN OUTCOMES AND MEASURES The primary end point was days with headache and the secondary end point was PedMIDAS (disability score range: 0-240 points; 0-10 for little to none, 11-30 for mild, 31-50 for moderate, >50 for severe); both end points were determined at 20 weeks. Durability was examined over the 12-month follow-up period. Clinical significance was measured by a 50% or greater reduction in days with headache and a disability score in the mild to none range (<20 points). RESULTS At baseline, there were a mean (SD) of 21 (5) days with headache per 28 days and the mean (SD) PedMIDAS was 68 (32) points. At the 20-week end point, days with headache were reduced by 11.5 for the CBT plus amitriptyline group vs 6.8 for the headache education plus amitriptyline group (difference, 4.7 [95% CI, 1.7-7.7] days; P = .002). The PedMIDAS decreased by 52.7 points for the CBT group vs 38.6 points for the headache education group (difference, 14.1 [95% CI, 3.3-24.9] points; P = .01). In the CBT group, 66% had a 50% or greater reduction in headache days vs 36% in the headache education group (odds ratio, 3.5 [95% CI, 1.7-7.2]; P < .001). At 12-month follow-up, 86% of the CBT group had a 50% or greater reduction in headache days vs 69% of the headache education group; 88% of the CBT group had a PedMIDAS of less than 20 points vs 76% of the headache education group. Measured treatment credibility and integrity was high for both groups. CONCLUSIONS AND RELEVANCE Among young persons with chronic migraine, the use of CBT plus amitriptyline resulted in greater reductions in days with headache and migraine-related disability compared with use of headache education plus amitriptyline. These findings support the efficacy of CBT in the treatment of chronic migraine in children and adolescents. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00389038.

Cognitive behavioral therapy for the treatment of juvenile fibromyalgia: A multisite, single-blind, randomized, controlled clinical trial

OBJECTIVE Juvenile fibromyalgia syndrome (FMS) is a chronic musculoskeletal pain disorder in children and adolescents for which there are no evidence-based treatments. The objective of this multisite, single-blind, randomized clinical trial was to test whether cognitive-behavioral therapy (CBT) was superior to fibromyalgia (FM) education in reducing functional disability, pain, and symptoms of depression in juvenile FMS. METHODS Participants were 114 adolescents (ages 11-18 years) with juvenile FMS. After receiving stable medications for 8 weeks, patients were randomized to either CBT or FM education and received 8 weekly individual sessions with a therapist and 2 booster sessions. Assessments were conducted at baseline, immediately following the 8-week treatment phase, and at 6-month followup. RESULTS The majority of patients (87.7%) completed the trial per protocol. Intent-to-treat analyses showed that patients in both groups had significant reductions in functional disability, pain, and symptoms of depression at the end of the study, and CBT was significantly superior to FM education in reducing the primary outcome of functional disability (mean baseline to end-of-treatment difference between groups 5.39 [95% confidence interval 1.57, 9.22]). Reduction in symptoms of depression was clinically significant for both groups, with mean scores in the range of normal/nondepressed by the end of the study. Reduction in pain was not clinically significant for either group (<30% decrease in pain). There were no study-related adverse events. CONCLUSION In this controlled trial, CBT was found to be a safe and effective treatment for reducing functional disability and symptoms of depression in adolescents with juvenile FMS.

Pain coping strategies that predict patients' and spouses' ratings of patients' self-efficacy

&NA; This study examined the relationship of pain coping strategies to osteoarthritis patients’ ratings of self‐efficacy and to spouses’ ratings of the patients’ self‐efficacy. Subjects, 130 individuals having osteoarthritis of the knees and persistent knee pain, completed a pain coping strategies measure (the Coping Strategies Questionnaire), a measure of self‐efficacy (the Arthritis Self‐Efficacy Scale), and a measure of pain (the McGill Pain Questionnaire). Two sets of regression analyses were conducted, one examining the degree to which pain coping strategies predicted patients’ self‐efficacy ratings, and the other examining the degree to which coping strategies predicted spouses’ ratings of the patients’ self‐efficacy. Several pain coping strategies were found to predict a significant proportion of variance in patients’ ratings of self‐efficacy: (i) ignoring pain sensations was related to higher self‐efficacy for pain; (ii) coping self statements were related to higher self‐efficacy for controlling other arthritis symptoms (e.g., fatigue or mood symptoms; and (iii) catastrophizing was related to lower self‐efficacy for pain, and self‐efficacy for other arthritis symptoms. Pain coping strategies were also found to predict a significant proportion of variance in spouses’ ratings of the patients’ self‐efficacy. Specifically: (i) diverting attention was related to lower spousal ratings of self‐efficacy for pain; (ii) praying or hoping was related to lower spousal ratings of self‐efficacy for function; and (iii) catastrophizing was related to lower spousal ratings of self‐efficacy for control of fatigue or mood symptoms. The findings regarding coping strategies were particularly interesting in that they were obtained even after controlling for pain intensity and demographic variables. The pain coping strategies identified are potentially important targets for cognitive‐behavioral assessment and treatment efforts. Interventions designed to increase the use of adaptive pain coping strategies and decrease the use of maladaptive pain coping strategies could enhance self‐efficacy, reduce pain, and improve the physical and psychological functioning of individuals having osteoarthritis.

Family factors, emotional functioning, and functional impairment in juvenile fibromyalgia syndrome.

OBJECTIVE Family factors and emotional functioning can play an important role in the ability of adolescents with juvenile primary fibromyalgia syndrome (JPFS) to cope with their condition and function in their everyday lives. The primary objectives of this study were to determine 1) whether adolescents with JPFS and their caregivers differed from healthy age-matched comparison peers and their caregivers in terms of emotional distress and functional impairment; 2) whether there were any differences in the family environment of adolescents with JPFS compared with healthy comparison peers; and 3) which individual-, caregiver-, and family-level variables were associated with functional impairment in adolescents with JPFS. METHODS Participants were 47 adolescents with JPFS recruited from a pediatric rheumatology clinic and 46 comparison peers without chronic illness matched for age, sex, and race. Participants and their caregivers (all mothers) completed a battery of standardized measures administered in their homes. RESULTS Adolescents with JPFS had greater internalizing and externalizing symptoms than healthy comparison peers. Mothers of adolescents with JPFS reported twice as many pain conditions and significantly greater depressive symptoms than mothers of comparison peers. The JPFS group also had poorer overall family functioning and more conflicted family relationships. In adolescents with JPFS, maternal pain history was associated with significantly higher functional impairment. CONCLUSION Increased distress and chronic pain are evident in families of adolescents with JPFS, and family relationships are also impacted. Implications for child functional impairment and the need for inclusion of caregivers in treatment are discussed.

Pain coping and the pain experience during mammography : a preliminary study

&NA; This study examined how pain coping efficacy and pain coping strategies were related to reports of pain during mammography. Subjects were 125 women over the age of 50 undergoing screening mammograms. Prior to their mammogram, all subjects completed the Coping Strategies Questionnaire (CSQ) to assess how they cope with day‐to‐day pain experiences. Ratings of pain during the mammogram were collected using a 6‐point pain/discomfort scale, a 100‐mm Visual Analog Scale, the adjective checklist of the McGill Pain Questionnaire, and the Brief Pain Inventory. Up to 93% of the women reported the mammogram examination was painful. On average, women rated the mammography pain in the low to moderate range. Considerable variability in pain ratings was found, however, with some women reporting severe pain and others reporting little or no pain. Correlational analyses were conducted to examine how coping efficacy (CSQ ratings of ability to decrease pain and ability to control pain) and coping strategies (CSQ pain coping strategy subscales) related to variations in pain report. There was a pattern for ratings of ability to decrease pain to be related to lower ratings of current mammography pain. Women who rated their ability to decrease pain as high reported lower average levels of mammography pain, lower ratings on the mammography pain/discomfort scale, and were much more likely to report having had lower levels of pain during their last mammogram. These findings suggest that women who rate their coping efficacy in decreasing day‐to‐day pain as low may be at higher risk for having a painful mammogram. Individual pain coping strategies were not generally correlated with pain ratings. Behavioral interventions (e.g., patient controlled breast compression) and cognitive therapy interventions (e.g., training in the use of calming self‐statements or distraction techniques) designed to increase coping efficacy potentially could be useful in reducing pain in women who are at risk for pain during mammography.

Changes in Pain Coping, Catastrophizing, and Coping Efficacy After Cognitive-Behavioral Therapy in Children and Adolescents With Juvenile Fibromyalgia

UNLABELLED A recent randomized multisite clinical trial found that cognitive-behavioral therapy (CBT) was significantly more effective than fibromyalgia education (FE) in reducing functional disability in adolescents with juvenile fibromyalgia (JFM). The primary objective of this study was to examine the psychological processes of CBT effectiveness by evaluating changes in pain coping, catastrophizing, and coping efficacy and to test these changes as mediators of continued improvements in functional disability and depressive symptoms at 6-month follow-up. One hundred adolescents (11-18 years old) with JFM completed the clinical trial. Coping, catastrophizing, and coping efficacy (Pain Coping Questionnaire) and the outcomes of functional disability (Functional Disability Inventory) and depressive symptoms (Childrens Depression Inventory) were measured at baseline, posttreatment, and 6-month follow-up. Participants in both conditions showed significant improvement in coping, catastrophizing, and efficacy by the end of the study, but significantly greater improvements were found immediately following treatment for those who received CBT. Treatment gains were maintained at follow-up. Baseline to posttreatment changes in coping, catastrophizing, and efficacy were not found to mediate improvements in functional disability or depressive symptoms from posttreatment to follow-up. Future directions for understanding mechanisms of CBT effectiveness in adolescents with chronic pain are discussed. PERSPECTIVE CBT led to significant improvements in pain coping, catastrophizing, and efficacy that were sustained over time in adolescents with juvenile fibromyalgia. Clinicians treating adolescents with JFM should focus on teaching a variety of adaptive coping strategies to help patients simultaneously regain functioning and improve mood.

The interplay of parent and adolescent catastrophizing and its impact on adolescents' pain, functioning, and pain behavior.

Objectives:Catastrophizing is a coping style linked to poorer patient outcomes. Little attention has focused on the parent-adolescent dyad and catastrophizing as a shared coping style. The purpose of this study was to: (1) examine the effects of adolescent and parent pain catastrophizing on adolescent functioning and (2) explore concordance in catastrophizing in parent-adolescent dyads, with equal interest in outcomes of dyads with discordant coping styles. Methods:Pain intensity, catastrophizing, depressive symptoms, quality of life, and pain behaviors were assessed in adolescents (ages 11 to 17) presenting to a pediatric chronic pain clinic (N=240). Results:Significant correlations between (1) parent and adolescent catastrophizing; (2) catastrophizing and pain behaviors; and (3) catastrophizing and adolescent outcomes were found. Parents and adolescents were classified into concordant or discordant dyads based on catastrophizing with a majority of dyads (>70%) showing concordant coping styles. Among discordant dyads, functional disability and depressive symptoms were significantly higher in a dyad with a high catastrophizing adolescent and low catastrophizing parent. Discussion:Results provide further support for catastrophizing being a maladaptive coping strategy for adolescents with pain and their parents. Greater adolescent catastrophizing was related to increased pain behaviors and poorer adolescent functioning. Parent catastrophizing also seems related to poorer adolescent outcomes, and most parent-adolescent dyads showed concordance in use of catastrophizing, which may suggest a shared tendency for adaptive or maladaptive styles of coping with pain. Future research should investigate pain coping at a dyadic or family level to explore how family coping styles magnify distress and disability or buffer adolescents from such problems.
