Executive Functioning and Self-Management Processes Mediate the Relationship Between Insomnia and Pain-Related Disability.

Insomnia has been identified as a predictor of reduced benefit from cognitive-behavioral treatment (CBT) for adolescent chronic pain; however, it is not well understood how insomnia leads to reduced treatment response. The purpose of this study was to evaluate executive function and self-management processes as 2 potential mediators of the relationship between insomnia symptoms and pain-related disability outcomes from internet-delivered CBT using a single-arm clinical trial design. Eighty-five adolescents with chronic pain (77% female, ages 12-17 years) and their caregiver received an 8-week internet-delivered CBT intervention. Youth completed validated measures of insomnia symptoms, executive function, self-management processes, and pain-related disability at baseline, mid-treatment, immediate post-treatment, and 3-month follow-up. Results from multilevel structural equation modeling indicated that more severe insomnia symptoms were associated with greater problems with executive function, which, in turn, led to lower engagement in self-management processes and less improvement in pain-related disability. These findings identify 2 mediators by which higher insomnia symptoms may lead to reduced benefit from CBT intervention for chronic pain. Research is needed to understand whether psychological treatments for chronic pain may be optimized by strategies targeting insomnia, executive function, and/or engagement in self-management. This trial was registered at clinicaltrials.gov (NCT04043962). PERSPECTIVE: Our study suggests that executive functioning and self-management processes mediate the relationship between insomnia and treatment outcomes for pediatric chronic pain, highlighting the impact of insomnia on youth learning and implementation of self-management strategies and the critical need for targeted sleep interventions in this population.

Household Food Insufficiency and Chronic Pain among Children in the US: A National Study.

This study aimed to determine the prevalence of pediatric chronic pain by household food sufficiency status and examine whether food insufficiency would be associated with greater risk for chronic pain. We analyzed data from the 2019-2020 National Survey of Children's Health of 48,410 children (6-17 years) in the United States. Across the sample, 26.1% (95% CI: 25.2-27.0) experienced mild food insufficiency and 5.1% (95% CI: 4.6-5.7) moderate/severe food insufficiency. The prevalence of chronic pain was higher among children with mild (13.7%) and moderate/severe food insufficiency (20.6%) relative to children in food-sufficient households (6.7%, p < 0.001). After adjusting for a priori covariates (individual: age, sex, race/ethnicity, anxiety, depression, other health conditions, adverse childhood events; household: poverty, parent education, physical and mental health; community: region of residence), multivariable logistic regression revealed that children with mild food insufficiency had 1.6 times greater odds of having chronic pain (95% CI: 1.4-1.9, p < 0.0001) and those with moderate/severe food insufficiency, 1.9 higher odds (95% CI: 1.4-2.7, p < 0.0001) relative to food-sufficient children. The dose-response relationship between food insufficiency and childhood chronic pain highlights the importance of further research to identify underlying mechanisms and evaluate the impact of food insufficiency on the onset and persistence of chronic pain across the lifespan.

Intervention for Sleep and Pain in Youth (ISPY-RCT): protocol for a two-phase randomized controlled trial of sequenced cognitive-behavioral therapy for insomnia and pain management in adolescents with migraine.

BACKGROUND: Migraine is a major pediatric health problem impacting 10-12% of youth. About 1 in 3 youth with migraine are diagnosed with insomnia. Sleep and migraine share a cyclical relationship, and data indicate that insomnia symptoms increase migraine severity. CBT for insomnia (CBT-I) has demonstrated efficacy for improving insomnia in adults with migraine and other pain conditions; however, effects in youth have not been evaluated. Moreover, in adults, there is some indication that CBT-I may lead to changes in pain after there are sustained improvements in sleep, but this has never been empirically tested. Cognitive-behavioral therapy for pain management (CBT-Pain) is an established treatment approach for youth with migraine, leading to reductions in headache frequency and disability. In the proposed study, we will address these gaps in knowledge by using an innovative two-phase trial design to (1) test the efficacy of Internet-delivered CBT-I intervention for youth with migraine and comorbid insomnia compared to Internet-delivered sleep education for modifying sleep and (2) investigate how changes in sleep may modify the response to Internet-delivered CBT-Pain intervention. METHODS: We will study a cohort of 180 adolescents, ages 11-17 years, with migraine (with or without aura, chronic migraine) and comorbid insomnia. In phase 1, youth will be randomly assigned to receive Internet-delivered CBT-I intervention or Internet sleep education control. In phase 2, all youth will receive Internet-delivered CBT-Pain intervention. Assessments will occur at baseline, immediately after phase 1 intervention, immediately after phase 2 intervention, and 6 months post-intervention. We will use a comprehensive multidimensional assessment of sleep and headache including self-report questionnaires, ambulatory actigraphy monitoring, and 14-day daily diaries. DISCUSSION: Given the high prevalence of insomnia in adolescents with migraine, an extension of CBT-I intervention to this population will address an important gap in clinical practice and in conceptual understanding of the relationship between sleep and migraine. By testing a separate CBT-I intervention, we will be able to apply this treatment in the future to other pediatric populations (e.g., cancer, arthritis) who commonly experience comorbid insomnia.

The impact of the COVID-19 pandemic on pain and psychological functioning in young adults with chronic pain.

ABSTRACT: Data are equivocal on the consequences of COVID-19 pandemic on pain and well-being for individuals with chronic pain. Furthermore, little is known regarding its impact on the health of young adults with chronic pain. We conducted a longitudinal study to compare pain, psychological functioning, and substance use before and during the pandemic of 196 young adults with chronic pain. Participants aged 18 to 24 years (M = 21.1 years; 79.6% females) reported on pain, anxiety, depression, and substance use before (October 2018-August 2019) and during the pandemic (October 2020-November 2020), in addition to the assessment of COVID-19 exposure and its impact. Before the pandemic, young adults experienced mild-to-moderate pain intensity (M = 3.75, SD = 2.33) and pain interference (M = 3.44, SD = 2.69). Findings were that pain intensity, pain interference, and depression symptoms remained stable during the pandemic. In contrast, anxiety symptoms increased significantly (M = 8.21, SD = 5.84 vs M = 8.89, SD = 5.95, P = 0.04). Tobacco, alcohol, and cannabis use were unchanged. Mixed linear models revealed that COVID-19 exposure and impact were not associated with changes in pain intensity or interference, with female sex associated with increased pain intensity (ß = 0.86, P = 0.02) and pain interference (ß = 0.87, P = 0.02). Our findings indicated relative stability of pain symptoms experienced by young adults with chronic pain. However, the increases in anxiety highlight the need to facilitate treatment access for mental health services to mitigate downstream impact.

Sleep Health Assessment and Treatment in Children and Adolescents with Chronic Pain: State of the Art and Future Directions.

Sleep is interrelated with the experience of chronic pain and represents a modifiable lifestyle factor that may play an important role in the treatment of children and adolescents with chronic pain. This is a topical review of assessment and treatment approaches to promote sleep health in children and adolescents with chronic pain, which summarizes: relevant and recent systematic reviews, meta-analyses, and methodologically sound prospective studies and clinical trials. Recommendations are provided for best practices in the clinical assessment and treatment of sleep health in youth with chronic pain. This overview can also provide researchers with foundational knowledge to build upon the best evidence for future prospective studies, assessment and intervention development, and novel clinical trials.

Baseline Sleep Disturbances Modify Outcome Trajectories in Adolescents With Chronic Pain Receiving Internet-Delivered Psychological Treatment.

Over 50% of adolescents with chronic pain report comorbid sleep disturbances (eg, difficulties with falling asleep), which is associated with increased pain-related disability and poorer quality of life. However, limited longitudinal data are available to understand how sleep disturbance may impact response to psychological treatment. Our primary hypothesis was that baseline sleep disturbances would significantly modify how adolescents responded to an internet-delivered psychological intervention for chronic pain in terms of outcome trajectories. The sample included 85 adolescents, 12 to 17 years, with chronic pain recruited from a multidisciplinary pain clinic and headache clinic who received access to an internet-delivered psychological intervention for chronic pain. Baseline sleep assessment included actigraphy monitoring for 7 days and survey measures. Outcomes were assessed at baseline, 8 weeks, and 3 months including core pain-related outcomes, executive functioning, fatigue, positive and negative affect. Results demonstrated that greater baseline insomnia and poorer sleep quality was associated with worse outcome trajectories for pain-related disability, depression, anxiety, fatigue, negative affect, and executive functioning. Findings extend the limited studies that examine how sleep disturbance may modify effectiveness of psychological treatments for adolescent chronic pain and emphasize the importance of treating comorbid sleep disturbance. This trial was registered at clinicaltrials.gov (NCT04043962). PERSPECTIVE: Our study suggests that sleep deficiency, in particular insomnia and poor sleep quality, may modify the effectiveness of psychological treatments for chronic pain, highlighting the urgent need to screen youth for sleep problems prior to initiating treatment, and to consider implementation of sleep-specific treatments such as cognitive-behavioral therapy for insomnia.

Internet Cognitive-Behavioral Therapy for Painful Chronic Pancreatitis: A Pilot Feasibility Randomized Controlled Trial.

INTRODUCTION: Severe abdominal pain is a cardinal symptom of chronic pancreatitis (CP) associated with a high economic and societal burden. In other chronic pain conditions, cognitive-behavioral therapy (CBT) has demonstrated efficacy in improving patient outcomes (e.g., pain-related disability and depression). However, CBT has not yet been evaluated in adult patients with painful CP. We aimed to (i) evaluate the feasibility and acceptability of an adapted Internet CBT program for CP and (ii) generate pilot data regarding the effects of treatment on patient pain outcomes. METHODS: Thirty adults (mean age = 49.8 years, SD = 12.5; 80% women) with suspected or definite CP were randomized to Internet CBT (Pancreatitis Pain Course) versus control. The Pancreatitis Pain Course has 5 CBT lessons (e.g., thought challenging, relaxation, and activity pacing) delivered over 8 weeks. Pain interference, pain intensity, and quality of life were assessed at pretreatment, posttreatment, and the 3-month follow-up. Qualitative interviews were conducted at posttreatment with a subset of participants. RESULTS: Eighty percent of participants rated the program as highly acceptable; 64.3% completed all 5 lessons. Qualitative data revealed positive perceptions of program features, relevancy, and skills. Patients randomized to Internet CBT demonstrated moderate to large effects in reducing pain intensity and pain interference from baseline to 3 months. The proportion of treatment responders (>30% improvement) was significantly greater in the Internet-CBT group than in the control group (50% vs 13%, Fisher exact t test P = 0.04). DISCUSSION: In this first trial of CBT pain self-management in CP, feasibility, acceptability, and preliminary efficacy for reducing pain and disability were demonstrated. Future definitive trials of CBT are needed.

Longitudinal study of early adaptation to the coronavirus disease pandemic among youth with chronic pain and their parents: effects of direct exposures and economic stress.

ABSTRACT: The novel coronavirus disease (COVID-19) has caused prolonged disruptions in daily life for many communities. Little is known about the impact of the COVID-19 pandemic on the health and well-being of youth with chronic pain and their families. We conducted a longitudinal, mixed-methods study to characterize early adaptation to the COVID-19 pandemic among 250 families of youth (ages 12-21 years) diagnosed with chronic headache (64%) or other chronic pain conditions (36%) and to determine whether direct exposures to COVID-19 and secondary economic stress modified symptom trajectories. Youth and parents reported on pain interference, anxiety, depression, and insomnia symptoms at 4 waves of data collection from April 2020 to July 2020. We also collected qualitative data on the impact of the pandemic on the youth's pain problem. Nearly half of our sample (49.6%) experienced direct exposures to COVID-19. Secondary economic stress was also common, affecting 44.4% of families. Symptom trajectories for pain, insomnia, depression, and anxiety remained stable or improved for most participants, indicating adaptive adjustment. However, overall symptom burden was high with persistent and clinically elevated depression, anxiety, and insomnia symptoms common among youth and parents. Direct exposures to COVID-19 did not modify symptom trajectories. However, youth pain interference and parent insomnia worsened in families who experienced secondary economic stress. Qualitative data revealed perceived benefits and harms from school closures on the youth's pain problem. Our findings of high symptom burden suggest that pediatric pain clinicians should offer distance assessment and treatment (eg, through telemedicine) to avoid pandemic-related disruptions in pain care.

Associations between insufficient sleep and prescription opioid misuse among high school students in the United States.

STUDY OBJECTIVES: The aim of this study was to estimate the association between insufficient sleep and prescription opioid misuse among US high school students. METHODS: Participants were 6,884 high school students who self-reported on sleep duration and prescription opioid misuse in the 2019 Youth Risk Behavior Survey. Sleep duration was categorized by the Youth Risk Behavior Survey according to the American Academy of Sleep Medicine guidelines as follows: recommended sleep duration (8-9 hours) vs insufficient sleep (< 8 hours). Participants also reported whether they had any prescription opioid misuse during their lifetime and whether they had prescription opioid misuse within the past 30 days. RESULTS: Most (79.4%) participants reported sleeping less than 8 hours per night. Among all youth, 12.9% reported lifetime prescription opioid misuse and 6.2% reported current prescription opioid misuse. Prevalence of both lifetime and current opioid medication misuse was higher among those also reporting insufficient sleep compared to those reporting recommended sleep duration (14.3% vs 7.7%, P < .0001 for lifetime misuse and 6.6% vs 4.3%, P = .0091 for current misuse). In multivariate models, insufficient sleep was associated with an increased odds of lifetime prescription opioid misuse (adjusted odds ratios = 1.4; 95% confidence interval, 1.1-1.2; P = .006); however, we did not find an association between sleep duration and current prescription opioid misuse in multivariate analysis. CONCLUSIONS: Sleep duration is associated with lifetime opioid misuse among US youth. Longitudinal studies are needed to test whether causal relationships exist, and to understand biobehavioral mechanisms that underlie associations between sleep deficiency and opioid misuse in adolescents.

Associations between adolescent sleep deficiency and prescription opioid misuse in adulthood.

STUDY OBJECTIVES: The main aim of this study was to estimate the association between sleep deficiency in adolescence and subsequent prescription opioid misuse in adulthood using United States nationally representative longitudinal data. METHODS: Self-reported data captured in the National Longitudinal Study of Adolescent to Adult Health at baseline (Wave 1; mean age = 16 years) and 12 year follow-up (Wave 4; mean age = 29 years). Participants (n = 12,213) reported on four measures of sleep during adolescence (Wave 1) and on lifetime prescription opioid misuse during adulthood (Wave 4). Associations between adolescent sleep and adult opioid misuse were estimated using multivariate logistic regression analysis controlling for sociodemographics, chronic pain, mental health, childhood adverse events, and a history of substance use. RESULTS: During adolescence, 59.2% of participants reported sleep deficiency. Prospectively, adolescents reporting not getting enough sleep, chronic unrestful sleep, and insomnia were associated with an increased risk for prescription opioid misuse (adjusted odds ratios [OR] = 1.2, p < 0.005 for all three variables). Short sleep duration was not associated with opioid misuse. CONCLUSION: This is the first study to longitudinally link sleep deficiency as an independent risk factor for the development of prescription opioid misuse. Sleep deficiency could be a driver of the opioid crisis affecting young people in the United States. Future studies should determine whether early and targeted sleep interventions may decrease risk for opioid misuse in high-risk patients prescribed opioids for pain.

Longitudinal Impact of Parent Factors in Adolescents With Migraine and Tension-Type Headache.

OBJECTIVE: To examine longitudinal associations between parent factors (parent headache frequency and disability, protective parenting behaviors, parent catastrophizing) with adolescent headache-related disability and headache frequency over 6 months. BACKGROUND: Theoretical models propose bidirectional, longitudinal relationships between parent factors and adolescent headache. Few studies have examined this using prospective study designs. DESIGN AND METHODS: Participants were a cohort of 239 youth ages 11-17 years with recurrent migraine (with and without aura; chronic migraine) or tension-type headache (episodic and chronic) and their parents recruited from a pediatric neurology clinic and the community who completed assessments at baseline and 6-month follow-up. RESULTS: After controlling for demographic and clinical covariates, we found that every point increase in baseline protective parenting behavior corresponded with a 2.19-point increase in adolescent headache frequency at follow-up (P = .026, 95% CI [0.27, 4.10]). Similarly, every point increase in baseline parent catastrophizing corresponded with a 0.93-point increase in adolescent headache-related disability (P = .029, 95% CI [0.09, 1.77]) and a .13-point increase in adolescent headache frequency (P = .042, 95% CI [0.01, 0.25]) at follow-up. We also found support for the reverse association, where every point increase in baseline adolescent headache-related disability predicted a 0.03-point increase in parent catastrophizing (P = .016, 95% CI [0.01, 0.05]) and a 0.02-point increase in protective parenting behavior (P = .009, 95% CI [0.01, 0.03]) at follow-up. The remaining bidirectional, longitudinal associations tested between parent factors and adolescent headache were not statistically significant. CONCLUSION: Findings suggest that family-based psychological interventions targeting modifiable adolescent and parent factors may lead to improvements in adolescent headache-related disability and reductions in adolescent headache frequency.

Challenges to successful research careers in neurology: How gender differences may play a role.

There has been a substantial rise in the number of women pursuing careers in neurology. However, research has shown that women in neurology have high rates of burnout with gender disparities in burnout and attrition in the field. Recently, there was a call from the NIH, including the National Institute of Neurological Disorders and Stroke, asking for input on factors that may limit or discourage grant applications from women. As the recipients of the highly coveted NIH career mentored awards (K awards) in headache medicine, we applaud the NIH for asking for gender-specific feedback and for raising awareness of research showing that female faculty on the Research Track are at an increased risk of departure. Using the NIH model for the Responsible Conduct of Research and the tenant of Nurturing the Fertile Environment, we discuss specific challenges in academic research that may contribute to gender differences in neurology research success. Although the rate of women conducting NIH-funded migraine research increased from 23% to 41% over the last 10 years, more women are currently in training compared with independence, with 6/6 of the NIH training grants but only 12/36 of the NIH research-level grants, held by women in fiscal years 2017-2019. We suggest concrete solutions to these challenges to ensure the success of women in research reaching independence.

Development and Validation of the Adolescent Insomnia Questionnaire.

OBJECTIVE: Insomnia is a highly prevalent sleep disorder that is particularly common among adolescents with health conditions. We aimed to develop and validate a brief screening measure of insomnia in adolescents that can be used across clinical and community samples. We hypothesized that we would identify evidence supporting reliability, convergent/discriminant validity, and that we would determine preliminary clinical cutoff scores. METHODS: A team of experts in behavioral sleep medicine developed a 13-item brief screening measure of insomnia in adolescents (Adolescent Insomnia Questionnaire [AIQ]). We evaluated the psychometric properties of the AIQ in a sample of 315 youth (11-18 years old, Mean = 14.90, SD = 2.02; 64% female) who had chronic pain (n = 37), headache (n = 170), insomnia diagnosed by a sleep specialist (n = 22), or were otherwise healthy (n = 86). RESULTS: Using Exploratory and Confirmatory Factor Analysis, we identified three subscales consistent with major diagnostic criteria of insomnia. As expected, the measure showed strong reliability through high internal consistency (α =.91). We also found strong convergent validity through expected positive relationships between the AIQ and self-report measures of sleep disturbance, and divergent validity via weak relationships with parent-report of snoring. Results of receiver operating characteristic (ROC) identified a clinical cutoff score that may assist in clinical decision making. CONCLUSIONS: We found that the AIQ has sound psychometric properties in a large heterogeneous sample of treatment-seeking youth and youth from the community. The AIQ can quickly screen adolescent insomnia and could address an important clinical need in identifying youth in need of insomnia treatment in pediatric practice settings.

The Interrelationship between Sleep and Chronic Pain in Adolescents.

Over half of youth with chronic pain report sleep deficiency including difficulties falling asleep, maintaining sleep, feeling unrested, and experiencing short sleep duration. Sleep deficiency has been shown to play a causal role in the development or worsening of chronic pain, and is associated with a variety of negative consequences for youth with chronic pain. The purpose of this review is to provide a summary of the literature on the interrelationship of sleep and chronic pain in adolescents. We review the impact and prevalence of sleep disturbances, conceptual models of the interrelationship of sleep and pain, biobehavioral mechanisms and risk factors, sleep assessment, and treatment of sleep deficiency and chronic pain in adolescents. Our recommendations for future research include understanding biobehavioral mechanisms that underlie the link between chronic pain and sleep deficiency to help guide development and testing of treatments for co-occurring pain and sleep disturbance in adolescents.

Economic Impact of Headache and Psychiatric Comorbidities on Healthcare Expenditures Among Children in the United States: A Retrospective Cross-Sectional Study.

OBJECTIVE: To examine the annual healthcare expenditures associated with childhood headache in the United States, and to evaluate whether psychiatric comorbidities increase the impact of headache on expenditures. BACKGROUND: Headache is prevalent in childhood and co-occurs with anxiety disorders, depressive disorders, and attention deficit/hyperactivity disorder (ADHD), which may increase cost of illness. METHODS: We conducted a secondary data analysis using a nationally representative sample of 34,633 children ages 2-17 from the 2012-2015 Medical Expenditure Panel Surveys (MEPS), of which 779 (weighted 2.6%) were identified as having headache based on health service use associated with headache. Using a comprehensive cost-of-illness approach, we assessed the incremental expenditures associated with headache and determined excess expenditures associated with psychiatric comorbidities using standard adjusted 2-part expenditure models. RESULTS: Annual total healthcare expenditures were estimated to be 24.3% higher, 95% CI [1,55], in our headache group ($3036, 95% CI [2374,3699] vs $2350, 95% CI [2140,2559]). Total national expenditures associated with pediatric headache in the United States were estimated at $1.1 billion annually, 95% CI [.04, 2.2 billion]. Depression and ADHD were associated with higher incremental expenditures for the headache group (depression: $1815, 95% CI[676,2953] vs $1409, 95% CI[697,2112]; ADHD: $4742, 95% CI[1659,7825] vs $2935, 95% CI[1977,3894]); however, interactions between psychiatric comorbidities and headache did not reach statistical significance. CONCLUSION: Youth with headache exert a considerable economic burden on families, healthcare systems, and society. Due to the limitations in methods used to classify youth with headache in MEPS, our findings may underestimate the true prevalence and cost of pediatric headache in the United States. Further research with larger sample sizes is needed to understand the impact of psychiatric comorbidities on healthcare expenditures in this population.

Screening Family and Psychosocial Risk in Pediatric Migraine and Tension-Type Headache: Validation of the Psychosocial Assessment Tool (PAT).

OBJECTIVE: To present data on psychometric properties of the Psychosocial Assessment Tool 2.0_General (PAT), a brief screener for psychosocial risk in families of youth with medical conditions, in youth with headache. BACKGROUND: Emotional and behavioral disturbances, parent distress, and poor family functioning are common among youth with recurrent migraine and tension-type headache; however, tools to comprehensively screen family and psychosocial risk in youth with headache are not currently available. The PAT could address an important gap by facilitating identification of psychosocial treatment needs among youth with headache. DESIGN AND METHODS: Youth with recurrent migraine (with and without aura; chronic migraine) or tension-type headache (episodic and chronic) completed the PAT and validated measures of adolescent emotional and behavioral functioning, parent emotional functioning, and family functioning at baseline (n = 239; 157 from neurology clinic, 82 from the community) and 6-month follow-up (n = 221; 146 from neurology clinic, 75 from the community). RESULTS: Internal consistency for the PAT Total score was strong (α = .88). At baseline, the PAT Total score was significantly associated in the expected direction with established measures of child emotional and behavioral functioning (r = .62), parent anxiety and depressive symptoms (r = .49; r = .53, respectively), and family functioning (r = .21). Predictive validity was demonstrated by a significant association between PAT Total scores at baseline with child emotional and behavioral functioning (r = .64), parent anxiety (r = .37), parent depression (r = .42), and family functioning (r = .26) at 6-month follow-up. CONCLUSIONS: The PAT is a promising tool for screening psychosocial risk that could facilitate identification of psychosocial treatment needs among youth with recurrent headache at risk for poor outcomes.

Understanding User Experience: Exploring Participants' Messages With a Web-Based Behavioral Health Intervention for Adolescents With Chronic Pain.

BACKGROUND: Delivery of behavioral health interventions on the internet offers many benefits, including accessibility, cost-effectiveness, convenience, and anonymity. In recent years, an increased number of internet interventions have been developed, targeting a range of conditions and behaviors, including depression, pain, anxiety, sleep disturbance, and eating disorders. Human support (coaching) is a common component of internet interventions that is intended to boost engagement; however, little is known about how participants interact with coaches and how this may relate to their experience with the intervention. By examining the data that participants produce during an intervention, we can characterize their interaction patterns and refine treatments to address different needs. OBJECTIVE: In this study, we employed text mining and visual analytics techniques to analyze messages exchanged between coaches and participants in an internet-delivered pain management intervention for adolescents with chronic pain and their parents. METHODS: We explored the main themes in coaches' and participants' messages using an automated textual analysis method, topic modeling. We then clustered participants' messages to identify subgroups of participants with similar engagement patterns. RESULTS: First, we performed topic modeling on coaches' messages. The themes in coaches' messages fell into 3 categories: Treatment Content, Administrative and Technical, and Rapport Building. Next, we employed topic modeling to identify topics from participants' message histories. Similar to the coaches' topics, these were subsumed under 3 high-level categories: Health Management and Treatment Content, Questions and Concerns, and Activities and Interests. Finally, the cluster analysis identified 4 clusters, each with a distinguishing characteristic: Assignment-Focused, Short Message Histories, Pain-Focused, and Activity-Focused. The name of each cluster exemplifies the main engagement patterns of that cluster. CONCLUSIONS: In this secondary data analysis, we demonstrated how automated text analysis techniques could be used to identify messages of interest, such as questions and concerns from users. In addition, we demonstrated how cluster analysis could be used to identify subgroups of individuals who share communication and engagement patterns, and in turn facilitate personalization of interventions for different subgroups of patients. This work makes 2 key methodological contributions. First, this study is innovative in its use of topic modeling to provide a rich characterization of the textual content produced by coaches and participants in an internet-delivered behavioral health intervention. Second, to our knowledge, this is the first example of the use of a visual analysis method to cluster participants and identify similar patterns of behavior based on intervention message content.

Evaluating the psychometric properties of the Widespread Pain Index and the Symptom Severity scale in youth with painful conditions.

BACKGROUND: Assessing features of centralized pain may prove to be clinically meaningful in pediatric populations. However, we are currently limited by the lack of validated pediatric measures. AIM: We examined the psychometric properties of the Widespread Pain Index (WPI) and Symptom Severity (SS) scale, to assess features of centralized pain, in youth with painful conditions from three clinical samples: (1) musculoskeletal surgery, (2) headache, and (3) chronic pain. METHODS: Participants were 240 youth aged 10-18 years (Mage=14.8, SD=1.9) who completed the WPI and SS scale. Subsets of participants also completed additional measures of pain region, pain intensity, quality of life, pain interference and physical function. RESULTS: Increased features of centralized pain by age were seen for the WPI (r=0.27, p<0.01) and SS scale (r=0.29, p<0.01). Expected differences in sex were seen for the WPI (sex:t132=-3.62, p<0.01), but not the SS scale (sex:t223=-1.73, p=0.09). Reliability for the SS scale was adequate (α=.70). Construct validity was demonstrated through relationships between the WPI and pain regions (r=.57, p<0.01), and between the SS scale and quality of life (r=-.59, p<0.01) and pain interference (r=.56, p<0.01). Criterion validity was demonstrated by differences on the WPI between the surgery sample and the headache and chronic pain samples (F2,237=17.55, p<0.001). Comprehension of the SS scale items was problematic for some youth. CONCLUSIONS: The WPI showed adequate psychometric properties in youth; however the SS scale may need to be modified. Our findings support the need to develop psychometrically sound instruments for comprehensive assessment of pain in pediatric samples.

Associations Between Adolescent Chronic Pain and Prescription Opioid Misuse in Adulthood.

Prescription opioid misuse is a serious public health concern, yet antecedent factors are poorly described. Using data from the National Longitudinal Study of Adolescent to Adult Health (N = 14,784), we examined the longitudinal relationship between a history of adolescent chronic pain and the odds of misusing prescription opioids in adulthood. The primary predictor variable was chronic pain status during adolescence. The primary outcome variables were prescription opioid misuse during early adulthood and adulthood. Multivariate models controlled for known risk factors of opioid misuse, including sociodemographics (sex, race, and ethnicity), adolescent mental health symptoms (anxiety, depression), adolescent self-reported physical health status, adolescent substance use/abuse, childhood trauma, and adult legitimate opioid use. We found that adults with a history of adolescent chronic pain were more likely to misuse opioids than those without history of chronic pain, even after controlling for other known risk factors. Further, we found that among individuals with history of adolescent chronic pain that race (white), other substance use, and exposure to trauma were risk factors for later opioid misuse. Longitudinal associations between adolescent chronic pain and subsequent adult prescription opioid misuse highlight the need for early targeted screening and prevention efforts that may reduce later opioid misuse. Perspective: Using a large, nationally representative sample, we found that chronic pain during adolescence was an independent risk factor for opioid misuse in adulthood, over and above other known risk factors. Furthermore, among those individuals with adolescent chronic pain, substance use, exposure to trauma, and race were associated with opioid misuse.
