Adolescent predictors of substance use in young adulthood among individuals with childhood-onset chronic pain: A follow-up study.

BACKGROUND: Adolescent chronic pain is a substantial public health problem, and pain symptoms often persist into adulthood. Young adults with chronic pain are at elevated risk for more frequent tobacco, alcohol and cannabis use, and cross-sectional research highlights the importance of psychosocial vulnerability factors. Limited research has examined how adolescent predictors, including mental health symptoms, pain, sleep and family functioning, impact later, young adult substance use. METHODS: A prospective cohort of 229 young adults (77.3% female; Mage = 21.0, SD = 1.6) with childhood-onset chronic pain completed measurements in adolescence and a follow-up assessment in young adulthood of past 3-month substance use frequency. RESULTS: Adolescent sleep quality and male sex were associated with more frequent tobacco use; adolescent depression was associated with more frequent alcohol use, and adolescent pain severity was associated with less frequent, and male sex was associated with more frequent cannabis use. CONCLUSIONS: Adolescent predictors of young adult substance use among youth with childhood-onset chronic pain represent important factors that may inform assessment, prevention and treatment of substance use in this population. Identifying and testing psychological interventions that target these vulnerability factors may reduce overall substance use risk in young adulthood. SIGNIFICANCE: This prospective observational study of young adults with childhood-onset chronic pain identified adolescent depression and sleep quality as vulnerability factors associated with substance use. Given the increasing risk for substance use during adolescence and young adulthood, these findings highlight the potential importance of early intervention to reduce substance use among young adults with childhood-onset chronic pain.

Protocol for a randomized controlled trial of an internet-based prevention intervention for young children at-risk for functional abdominal pain.

BACKGROUND: Chronic pain often clusters in families, where parents and their offspring both experience chronic pain conditions. Young children of parents with irritable bowel syndrome (IBS) represent an at-risk group for the development of abdominal pain, disability, and excess health care visits in later childhood. Parental solicitous responses to children's expressions of discomfort and maternal modeling of their own illness behavior contribute to a greater focus on somatic sensations, leading to illness behaviors in children. This randomized controlled trial will test the effectiveness of an early preventive web-based psychosocial intervention (REACH)[TM] vs. an educational web-based safety comparison condition delivered to parents with IBS to alter parental responses and lead to improved child health and decreased health care costs. METHODS: Parents with IBS who have children ages 4-7 years are recruited via community-based approaches (e.g., social media advertisements, school electronic distribution, research networks) and health care providers. The target sample is 460 parents randomized to REACH, a web-based social learning and cognitive behavior therapy (SLCBT) intervention or an educational web-based safety comparison condition (EC). Participants will be assessed at baseline, 6-week (immediate post-intervention), 6-month, 12-month, and 18-month follow-up periods (months post-completion of intervention). The primary outcome is change in parental solicitous/protective behaviors. Secondary outcomes include parent risk and protective factors, child health and symptom outcomes, and health care utilization and cost savings. DISCUSSION: This study adapts a validated, parent-delivered intervention to treat chronic pain in children to a web-based application designed to prevent the development of chronic pain in very young, high-risk children. If successful, this strategy can both prevent adverse sequelae of this condition from developing as well as be widely accessible. Furthermore, the availability of a prevention model for parent training could result in significant short- and long-term health benefits across a broad spectrum of conditions.

Prevalence, pain trajectories, and presurgical predictors for chronic postsurgical pain in a pediatric sample in Spain with a 24-month follow-up.

ABSTRACT: Pediatric chronic pain, particularly chronic postsurgical pain (CPSP), poses a significant public health challenge, impacting 20% of pediatric populations. While several presurgical predictors have been identified, there is a scarcity of data on long-term outcomes, especially beyond 1 to 2 years postsurgery. Previous research primarily focuses on North American children, creating gaps in understanding CPSP outcomes in diverse health systems, such as in Spain. This study, registered as NCT04735211, investigates CPSP in 159 children and adolescents (mean age = 12.4 years, 37.1% girls, retention rate = 65%) undergoing various surgeries in Spain. The objectives include examining CPSP prevalence (Numerical Rating Scale ≥ 4) at 3, 6, 12, and 24 months, exploring postsurgical pain trajectories through group-based trajectory modeling, and identifying potential presurgical predictors for CPSP (pain intensity, pain catastrophizing, pain anxiety, fear of pain, kinesiophobia, health-related quality of life, pain interference, and physical activity), using multiple logistic regressions. Results show a CPSP prevalence of 41% at 3 months, decreasing to 14% at 24 months. Presurgical factors including pain intensity (adjusted odds ratio [aOR] = 1.25, 95% confidence interval [CI] = 1.02-1.53), pain catastrophizing (aOR = 1.06, 95% CI = 1.00-1.13), and pain anxiety (aOR = 1.06, 95% CI = 1.02-1.11) were associated with CPSP at 3 months. Group-based trajectory modeling revealed 3 postsurgical pain trajectories: Low Pain with Rapid Recovery Group (30.2%), Moderate Pain with Recovery Group (53.5%), and High Pain with Slow Recovery Group (16.3%), with group differences in presurgical predictors, excluding physical activity. This study contributes valuable insights into CPSP, emphasizing the need for long-term follow-up. The findings could inform the implementation of preventive programs for CPSP into diverse health systems.

TikTok and teen mental health: an analysis of user-generated content and engagement.

BACKGROUND: TikTok is a social media mobile application that is widely used by adolescents, and has the potential to serve as a revolutionary platform for public and mental health discourse, education, and intervention. OBJECTIVE: Our study aimed to describe the content and engagement metrics of the hashtag #teenmentalhealth on TikTok. METHODS: In this study, we: (a) conducted a directed content analysis of the Top 100 TikTok videos tagged with #teenmentalhealth, and (b) collected data on video engagements (views, likes, saves, and shares) and computed view-based engagement rates. RESULTS: The videos collectively garnered 144,320,591 views; 28,289,655 likes; 219,780 comments; 1,971,492 saves; and 478,696 shares. Most of the generated content were from teens and therapists. Engagement metrics revealed strong user engagement rates across user types. The most prevalent content categories represented across videos were personal experience, coping techniques or treatment, humor, interpersonal relationships, and health campaign. The content categories with the highest engagement rates were relatable media representation, health campaign, social isolation, and humor. Only a single video incorporated evidence-based treatment content. CONCLUSION: TikTok facilitates communication and information dissemination on teen mental health. Future research should focus on improving the quality and credibility of digital content while maintaining engagement through creativity, self-expression, and relatability. Use of popular social media platforms and community-engaged research to disseminate evidence-based content may help bridge the translational research gap.

Mobile App Promoting Resilience in Stress Management for Adolescents and Young Adults With Cancer: Protocol for a Pilot Randomized Controlled Trial.

BACKGROUND: Adolescents and young adults (AYAs) with cancer are at risk of poor psychosocial outcomes. AYAs grew up with the internet and digital technology, and mobile Health (mHealth) psychosocial interventions have the potential to overcome care access barriers. OBJECTIVE: This pilot randomized controlled trial (RCT) aimed to establish the feasibility, acceptability, and preliminary efficacy of a fully automated mobile app version of the Promoting Resilience in Stress Management intervention (mPRISM). Promoting Resilience in Stress Management is an evidence-based intervention developed in collaboration with AYAs, based on stress and coping theory, resilience theory, and evidence-based coping strategies. We hypothesized that mPRISM would be feasible, acceptable, and appropriate. METHODS: This is a parallel, 2-arm, single-site pilot RCT with a waitlist control design. The study will recruit 80 AYAs with cancer from a clinic. Eligible AYAs are aged 12 to 25 years, within 12 months of a new cancer diagnosis, receiving chemotherapy or radiation therapy, speak, read, or write in English, and are cognitively able to participate in study procedures. Recruitment by clinical research coordinators will occur remotely by phone, video, or text. Participants will be randomized to psychosocial usual care (UC) alone or UC plus mPRISM for an 8-week intervention period, and will remain unblinded to study condition. Enrolled participants will complete surveys at baseline before randomization, 8 weeks, and 3-month follow-up. Using a waitlist design, the UC arm will receive mPRISM upon completion of 3-month follow-up surveys. Those in the UC arm will complete 2 additional measurement points at immediate posttreatment and 3 months later. The primary outcomes of interest are feasibility, defined as ≥60% enrollment and ≥70% retention (ie, percentage of participants who completed the study), and "feasibility, acceptability, and appropriateness" as defined by cut-off scores ≥4/5 on 3 brief validated implementation outcome measures (feasibility of implementation measure, acceptability of intervention measure [AIM], intervention appropriateness measure [IAM]). We will apply top-box scoring for the implementation measures. Exploratory outcomes of interest include patient-reported health-related quality of life, resilience, distress, anxiety, depression, pain, and sleep. We will conduct an intention-to-treat analysis to compare the outcomes of the mPRISM arm versus the control arm with covariate-adjusted regression models. We will summarize individual digital usage metrics using descriptive statistics. RESULTS: Since September 2023, we have enrolled 20 participants and recruitment is ongoing. CONCLUSIONS: Although our previous work suggests AYAs with cancer are interested in mHealth psychosocial interventions, such interventions have not yet been sufficiently evaluated or implemented among AYA oncology patients. mPRISM may serve as a potential mHealth intervention to fill this gap. In this study, we will test the feasibility, acceptability, and preliminary efficacy of mPRISM. This work will inform future larger-scale RCTs powered for efficacy outcomes.

Ecological momentary assessment of sleep, pain, and opioid use among adolescents following surgery.

Background: Opioids are effective for acute pain management following surgery among adolescents, yet are associated with significant negative consequences, including respiratory depression and opioid misuse. Sleep deficiency is common following surgery and extant research indicates strong cross-sectional associations between sleep deficiency and increased problematic opioid use. Objective: This study examined longitudinal associations between postsurgical sleep deficiency and opioid use among adolescents undergoing outpatient surgery. We also examined daily pain and mood as mechanisms linking previous night's sleep deficiency and next day prescription opioid use. Methods: This prospective, observational study enrolled 106 adolescents (11-19 years) who underwent orthopedic outpatient surgery and collected pre-surgery and longitudinal measurements. Participants were 52% female, African-American (7%), American Indian/Alaska Native (7%), Hispanic (9%), Native Hawaiian or Other Pacific Islander (4%), or white, non-Hispanic (66%). Using ecological momentary assessment methods, participants reported sleep, pain, and mood in real time over the first 14 days following surgery. Postsurgical opioid use was measured using an electronic medication cap monitoring device, eCAPTM. Associations between variables were measured using multilevel structural equation modeling. Results: Using multi-level mediation models, pain, but not mood-mediated associations between postsurgical sleep deficiency (sleep quality, total sleep time, sleep onset latency, and wake after sleep onset) and opioid use, at both the within-person and between-person levels. Results highlight that greater previous night's sleep deficiency (both generally and greater than a person's mean level) was associated with higher next day pain (both generally and greater than a person's mean level), which, in turn, was associated with higher opioid use. Furthermore, between-person total effect models provide support for sleep deficiency predicting higher opioid use. Conclusions: Our findings should be considered preliminary yet underscore the need for a comprehensive and personalized approach to postsurgical pain management and opioid use, potentially implementing interventions targeting sleep quality and quantity to reduce pain and opioid use.

Adolescent predictors of young adult pain and health outcomes: results from a 6-year prospective follow-up study.

ABSTRACT: Adolescent chronic pain may lead to persistent disability and long-term health impairments in adulthood. However, our understanding of which youth are more likely to experience adverse outcomes remains limited. To address this gap, this longitudinal cohort study examined adolescent predictors of various dimensions of young adult health and functioning, including pain, physical health, depression, anxiety, social isolation, and sleep disturbance. As part of a previous clinical trial, we recruited a cohort of adolescents (ages 11-17 years, M age = 14 years) with non-disease-related chronic pain from 15 tertiary pain clinics in North America. Approximately 6 years later, 229 of the original 273 individuals (81% participation rate) completed a follow-up survey as young adults (ages 18-25 years, M age = 21 years). At the young adult follow-up, 73% reported continued chronic pain, with two-thirds experiencing moderate-to-severe pain interference. Youth reported several adverse health outcomes, including below-average physical health (37%), clinically elevated depression (42%), clinically elevated anxiety (48%), and sleep disturbances (77%). Multivariate regression analyses controlling for sociodemographic characteristics revealed that higher pain intensity, more pain locations, lower sleep quality, and greater anxiety symptoms in adolescence predicted worse pain outcomes in young adulthood. Moreover, lower sleep quality, greater anxiety symptoms, and worse family functioning predicted worse physical and psychosocial health in adulthood. These findings represent an important first step toward identifying ways to optimize psychological pain interventions. Tailored psychological pain interventions can directly target adolescent vulnerabilities, including mood, sleep, and family risk factors, with the potential to disrupt a lifelong trajectory of pain and suffering.

Adolescent Girls' Musculoskeletal Pain is More Affected by Insomnia Than Boys, and Through Different Psychological Pathways.

Prior research has established that insomnia is predictive of pain in adolescents and that psychological mechanisms have a crucial role in this relationship. Adolescent girls report more insomnia and pain than boys, yet little is known of gender differences in how insomnia influences pain. This study assessed gender differences in levels and trajectories of insomnia and pain during adolescence, and whether rumination and negative mood mediated the effect of insomnia on pain. Longitudinal survey data measured on 5 annual occasions (Nbaseline = 2,767) were analyzed in a multigroup longitudinal serial mediation model. A final model was generated with insomnia as the predictor, rumination and depressed mood as mediators, pain as the outcome, and gender as the grouping variable. The results showed that insomnia predicted pain in adolescents, with an effect 3.5 times larger in girls than boys. Depressed mood was the main mediator in boys. In girls, rumination was the only significant mediator. There were significant gender differences in the effects of insomnia on rumination and pain, and in the effects of rumination on depressed mood and pain, with stronger effects in girls. These results highlight that girls and boys should be considered separately when studying the relationship between insomnia and pain. PERSPECTIVE: Levels of insomnia and pain are progressively higher in adolescent girls than boys, across adolescence. The predictive strength of insomnia symptoms for future pain is 3.5 times greater in girls, with distinct gender-specific underlying pathways: rumination partially mediates this effect in girls, while depressed mood does so in boys.

Influence of chronotype on pain incidence during early adolescence.

ABSTRACT: During adolescence major shifts in sleep and circadian systems occur with a notable circadian phase delay. Yet, the circadian influence on pain during early adolescence is largely unknown. Using 2 years of data from the Adolescent Brain Cognitive Development study, we investigated the impact of chronotype on pain incidence, moderate-to-severe pain, and multiregion pain 1 year later in U.S. adolescents. Based on the Munich ChronoType Questionnaire, chronotype was calculated as the midpoint between sleep onset and offset on free days, corrected for sleep debt over the week. Adolescents reported pain presence over the past month, and if present, rated pain intensity (0-10 numerical rating scale; ≥ 4 defined as moderate-to-severe pain) and body site locations (Collaborative Health Outcomes Information Registry Body Map; ≥2 regions defined as multiregion pain). Three-level random intercept logistic regression models were specified for each pain outcome, adjusting for baseline sociodemographic and developmental characteristics. Among 5991 initially pain-free adolescents (mean age 12.0 years, SD 0.7), the mean chronotype was 3:59 am (SD 97 minutes), and the 1-year incidence of pain, moderate-to-severe pain, and multiregion pain was 24.4%, 15.2%, and 13.5%, respectively. Each hour later chronotype at baseline was associated with higher odds of developing any pain (odds ratio [OR] = 1.06, 95% confidence interval [CI] = 1.01, 1.11), moderate-to-severe pain (OR = 1.10, 95% CI = 1.05-1.17), and multiregion pain (OR = 1.08, 95% CI = 1.02-1.14) during 1-year follow-up. In this diverse U.S. adolescent sample, later chronotype predicted higher incidence of new-onset pain.

Sleep deficiency and symptoms of pain, fatigue, and depressed mood in youth with and without childhood systemic lupus erythematosus.

STUDY OBJECTIVES: To describe and compare sleep deficiency and symptoms of pain, fatigue, and depressed mood in youth with childhood Systemic lupus erythematosus (cSLE) to a healthy comparison group of youth; and to test the associations between sleep and symptoms of pain, fatigue, and depressed mood in youth with cSLE. METHODS: Forty-three youth (23 youth with cSLE; 20 age, sex-matched healthy youth) wore actigraphs and completed sleep diaries for 10 days, and completed self-report questionnaires on sleep quality, pain, fatigue, and depressed mood. RESULTS: On average, both groups had a total sleep time of less than 7 hours. Youth with cSLE had worse sleep efficiency (73.3%) and sleep regularity index scores (55.4) compared to the healthy comparison group of youth (79.2%, 60.1, respectively). Youth with cSLE had worse pain (p = .03) and fatigue (p = .004) compared to the healthy comparison group. Negative associations were found among self-reported sleep quality, sleep satisfaction, and symptoms of pain, fatigue, and depressed mood in youth with cSLE and wake after sleep onset was positively associated with fatigue. CONCLUSIONS: Poor sleep efficiency and sleep irregularity accompanied by symptoms of pain, fatigue, and depressed mood was prevalent in youth with cSLE. Youth with lupus should be encouraged to maintain a regular sleep schedule. Since, this is the first study to incorporate objective sleep and sleep regularity measures in youth with cSLE, additional studies with objective and self-report sleep measures are needed to replicate our findings.

Pain Catastrophizing Moderates the Relationship Between Pain Sensitivity and Clinical Pain in Adolescents With Functional Abdominal Pain.

Pain catastrophizing has been linked to amplified pain sensitivity assessed using quantitative sensory testing (QST) in adults; pediatric data are limited, particularly in youth with functional abdominal pain (FAP). With increasing use of QST to evaluate somatosensory function and predict pain outcomes, we examined the associations between QST and clinical pain in adolescents with FAP and tested the moderating effects of pain catastrophizing. Seventy-seven adolescents (mean age 16.6 years, 85.7% female, 72.7% White, 90.8% non-Hispanic) who fulfilled diagnostic criteria for FAP completed QST assessment (pressure pain threshold and tolerance, heat pain threshold, conditioned pain modulation) and measures of abdominal pain intensity, pain interference, and pain catastrophizing. Adjusting for age and sex, only higher heat pain threshold was associated with higher abdominal pain intensity (Beta per 1-standard deviation = .54, P = .026). Contrary to hypothesis, for youth with higher pain catastrophizing, higher pressure pain tolerance was associated with greater abdominal pain intensity, but associations were not significant for youth with lower catastrophizing (P = .049). Similarly, for those with higher pain catastrophizing (in contrast to lower pain catastrophizing), higher pressure pain thresholds and tolerance were associated with higher pain interference (P = .039, .004, respectively). Results highlight the need to investigate the influence of pain catastrophizing on QST. PERSPECTIVE: This study demonstrated unexpected findings of pain catastrophizing moderating the relationships between pressure pain threshold and tolerance, and clinical pain in adolescents with FAP. This raised questions regarding our understanding of psychological contributions to QST findings in pediatric populations with chronic pain.

Interventions for Pancreatitis-New Approaches, Knowledge Gaps, and Research Opportunities: Summary of a National Institute of Diabetes and Digestive and Kidney Diseases Workshop.

ABSTRACT: There exists no cure for acute, recurrent acute or chronic pancreatitis and treatments to date have been focused on managing symptoms. A recent workshop held by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) focused on interventions that might disrupt or perhaps even reverse the natural course of this heterogenous disease, aiming to identify knowledge gaps and research opportunities that might inform future funding initiatives for NIDDK. The breadth and variety of identified active or planned clinical trials traverses the spectrum of the disease and was conceptually grouped for the workshop into behavioral, nutritional, pharmacologic and biologic, and mechanical interventions. Cognitive and other behavioral therapies are proven interventions for pain and addiction, but barriers exist to their use. Whilst a disease specific instrument quantifying pain is now validated, an equivalent is lacking for nutrition - and both face challenges in ease and frequency of administration. Multiple pharmacologic agents hold promise. Ongoing development of Patient Reported Outcome (PRO) measurements can satisfy Investigative New Drug (IND) regulatory assessments. Despite multiple randomized clinical trials demonstrating benefit, great uncertainty remains regarding patient selection, timing of intervention, and type of mechanical intervention (endoscopic versus surgery). Challenges and opportunities to establish beneficial interventions for patients were identified.

Sexual Orientation/Gender Identity Discrimination and Chronic Pain in Children: A National Study.

INTRODUCTION: This study provides national estimates of parental perceived child sexual orientation or gender minority (SGM) discrimination and examines associations between SGM discrimination and chronic pain in children. METHODS: Cross-sectional analysis of the 2020 and 2021 National Survey of Children's Health (N=47,213). Caregivers of children ages 6-17 years old reported whether their child had ever been treated or judged unfairly (i.e., discrimination) because of their SGM identity. Chronic pain in children was defined as frequent or chronic difficulty with repeated or chronic physical pain during the past 12 months, as reported by caregivers. Weighted prevalence estimates for discrimination were calculated for the whole sample and sociodemographic subgroups. Associations between SGM discrimination and chronic pain were estimated using multivariable Poisson regression models adjusting for sociodemographic factors. Analyses were conducted 2022-2023. RESULTS: Within this nationally representative sample, parents reported 1.4% (95% CI 1.2%-1.6%) of children have experienced SGM-related discrimination. The prevalence was higher among adolescents, females at birth, and those living in suburban areas. Children who experienced discrimination had a higher prevalence of chronic pain (20.2%) compared to those who did not (7.0%, p<0.0001), with an adjusted prevalence rate ratio of 2.0 (95% CI 1.5-2.5, p<0.0001). CONCLUSIONS: Based on parent report, about 0.6 million children in the U.S. have experienced SGM-based discrimination; these children are twice as likely to have chronic pain. Findings highlight the importance of assessment and intervention for chronic pain in children who may experience marginalization and discrimination due to their sexual orientation and gender identity.

Prescription Opioid Decision-making and Use Behaviors in Adolescents With Acute Pain: A Qualitative Study.

OBJECTIVES: Understanding adolescent perspectives on prescribed opioids in the context of medical care for acute pain is needed to prevent opioid-related adverse outcomes. We explored factors that may influence opioid decision-making and use behaviors among adolescents prescribed opioids for acute pain. METHODS: We conducted semistructured interviews with 19 adolescents (63% females, ages 12 to 17) prescribed opioids upon discharge from surgery or intensive care unit admission. Interview transcripts were coded using inductive thematic analysis. RESULTS: Five themes were identified: "Opioid use to reduce extreme pain and facilitate acute recovery"; "Familiarity with risks and negative effects of opioids"; "Assessment of opioid risk based on individual characteristics and use behaviors"; "Careful balance of risks, benefits, and symptoms when taking opioids"; "Importance of trusted adults for adolescent opioid management". Adolescents commonly believe opioids are only appropriate for severe pain that cannot be managed with other strategies. Most (but not all) adolescents were aware of addiction and other potential opioid harms and generally disapproved of misuse. However, a few adolescents would consider taking unprescribed opioids for severe pain. Adolescents wanted to be well informed for opioid decision-making, considering guidance from trusted adults. DISCUSSION: Adolescents often demonstrated active and sound participation in shared opioid decision-making, influenced by complex integration of inputs and self-reflection. Conversely, potential factors that could contribute to risky behaviors included low personal risk perceptions, uncertainty about what constitutes opioid misuse, and avoidance of prescribed opioids despite extreme pain. Future studies may explore associations of adolescents' opioid decision-making with longer-term pain and opioid-related outcomes.

A cognitive-behavioral digital health intervention for sickle cell disease pain in adolescents: a randomized, controlled, multicenter trial.

ABSTRACT: Severe acute and chronic pain are the most common complications of sickle cell disease (SCD). Pain results in disability, psychosocial distress, repeated clinic visits/hospitalizations, and significant healthcare costs. Psychosocial pain interventions that teach cognitive and behavioral strategies for managing pain have been effective in other adolescent populations when delivered in person or through digital technologies. Our aim was to conduct a multisite, randomized, controlled trial to improve pain and coping in youth aged 12 to 18 years with SCD using a digital cognitive-behavioral therapy program (iCanCope with Sickle Cell Disease; iCC-SCD) vs Education control. We enrolled 137 participants (ages 12-18 years, 59% female) and analyzed 111 adolescents (107 caregivers), 54 randomized to Education control and 57 randomized to iCC-SCD. Ninety-two percent of youth completed posttreatment assessments and 88% completed 6-month follow-up. There was a significant effect of treatment group (iCC-SCD vs Education) on reduction in average pain intensity from baseline to 6-month follow-up (b = -1.32, P = 0.009, 95% CI [-2.29, -0.34], d = 0.50), and for the number of days with pain, adolescents in the iCC-SCD group demonstrated fewer pain days compared with the Education group at 6-month follow-up (incident rate ratio = 0.63, P = 0.006, 95% CI [0.30, 0.95], d = 0.53). Treatment effects were also found for coping attempts, momentary mood, and fatigue. Several secondary outcomes did not change with intervention, including anxiety, depression, pain interference, and global impression of change. Future studies are needed to identify effective implementation strategies to bring evidence-based cognitive-behavioral therapy for sickle cell pain to SCD clinics and communities.

Longitudinal Pain Outcomes Following an Intensive Pediatric Pain Rehabilitation Program: Testing Potential Treatment Mechanisms.

OBJECTIVES: This study tested performance measures of physical functioning and pain-related psychosocial measures as potential mechanisms of improvements in outcomes following intensive outpatient interdisciplinary pain rehabilitation for adolescents. We hypothesized that improvements in performance measures of physical functioning, fear of pain, pain catastrophizing, and self-efficacy during treatment would be related to improvements in pain, functional disability, and depressive symptoms. METHODS: Seventy-seven adolescents, 10 to 18 years old, completed self-report measures before treatment, after the first week, at discharge, and at the 3-month follow-up. Participants completed physical performance measures of physical and exercise capacity and core strength on day 1, after the first week, and at discharge. Linear mixed models were used to examine the association between changes in potential mechanisms and changes in outcomes, adjusting for age, sex, pain duration, and baseline functional disability. RESULTS: Statistically significant improvement in functional disability, pain, and depressive symptoms was demonstrated across the 4 time points. Improvements were also demonstrated in physical performance measures, fear of pain, pain catastrophizing, and self-efficacy. Improvements in pain catastrophizing predicted improvements in functional disability, pain, and depressive symptoms. Improvements in self-efficacy predicted improvements in all outcome variables except depression. Improvements in physical performance measures predicted improvements in some aspects of functional disability and pain, but not depressive symptoms. DISCUSSION: This study contributes to the growing literature on the effectiveness of pediatric intensive interdisciplinary pain rehabilitation programs and mechanisms that influence improvements in outcomes, an area that is currently underexplored. Results are important to guide future research and inform clinical practice.

Recommendations for Patient-Reported Outcomes Measurement Information System pediatric measures in youth with chronic pain: a COnsensus-based Standards for the selection of health Measurement INstruments systematic review of measurement properties.

ABSTRACT: The Patient-Reported Outcome Measurement Information System (PROMIS) pediatric measures assess physical, emotional, and social health among children and adolescents. However, their measurement properties have not been systematically examined in youth with chronic pain. A systematic review applying the COnsensus based Standards for the selection of health Measurement INstruments (COSMIN) methodology was conducted to evaluate self-reported PROMIS pediatric measures in youth with chronic pain, assessing 8 measurement properties across all versions (item bank, short form, and computer adaptive testing) from 63 studies covering 25 measures. Moderate or high-quality evidence was most available for content validity, structural validity, internal consistency (measurement precision), and construct validity. Four short-form PROMIS pediatric measures-mobility, anxiety, depressive symptoms, and physical stress experiences-achieved recommendation for the use in chronic pain clinical trials; 7 approached recommendation and 14, including the commonly used PROMIS Pediatric Pain Interference Scale, would be recommended with further evidence. Recommendations were also provided for the use of each measure in observational studies. Overall, based on the existing evidence, a total of 11 self-reported PROMIS pediatric short-form measures, including pain intensity, pain behavior, mobility, sleep disturbance, sleep-related impairment, anxiety, depressive symptoms, psychological stress experiences, physical stress experiences, family relationships, and positive effect, are recommended or approaching recommendation for use in youth ages 8 to 19 years with chronic pain. Research is needed to further establish test-retest reliability, measurement errors, cross-cultural validity, and responsiveness. Future work should expand the evaluation of PROMIS pediatric measures in subpopulations of youth with chronic pain, particularly young children and those with neurodevelopmental disabilities.
