PROMIS® Parent Proxy Report Scales for children ages 5-7 years: an item response theory analysis of differential item functioning across age groups

Association of mental health-related patient reported outcomes with blood pressure in adults and children with primary proteinuric glomerulopathies

INTRODUCTION

The prevalence of mental health disorders including anxiety and depression is increasing and is linked to hypertension in healthy individuals. However, the relationship of psychosocial patient-reported outcomes on blood pressure (BP) in primary proteinuric glomerulopathies is not well characterized. This study explored longitudinal relationships between psychosocial patient-reported outcomes and BP status among individuals with proteinuric glomerulopathies.

METHODS

An observational cohort study was performed using data from 745 adults and children enrolled in the Nephrotic Syndrome Study Network (NEPTUNE). General Estimating Equations for linear regression and binary logistic analysis for odds ratios were performed to analyze relationships between the exposures, longitudinal Patient-Reported Outcome Measurement Information System (PROMIS) measures and BP and hypertension status as outcomes.

RESULTS

In adults, more anxiety was longitudinally associated with higher systolic and hypertensive BP. In children, fatigue was longitudinally associated with increased odds of hypertensive BP regardless of the PROMIS report method. More stress, anxiety, and depression were longitudinally associated with higher systolic BP index, higher diastolic BP index, and increased odds of hypertensive BP index in children with parent-proxy patient-reported outcomes.

DISCUSSION/CONCLUSION

Chronically poor psychosocial patient-reported outcomes may be significantly associated with higher BP and hypertension in adults and children with primary proteinuric glomerulopathies. This interaction appears strong in children but should be interpreted with caution, as multiple confounders related to glomerular disease may influence both mental health and BP independently. That said, access to mental health resources may help control BP, and proper disease and BP management may improve overall mental health.

Simplified Chinese version of the PROMIS Pediatric-25 profile: A validation study among cancer children

PURPOSE

Pediatric cancer is a significant health concern in China, and evaluating the impact of cancer and its treatment on the well-being of young patients is essential for both clinical care and research purposes. This study aimed to psychometrically validate the Patient-reported Outcomes Measurement Information System Pediatric-25 Profile (PROMIS-Pediatric-25) among Chinese children with cancer.

DESIGN AND METHODS

We enrolled a group of 114 children living with cancer between the ages of 8 and 17. Each participant completed questionnaires that covered sociodemographic and clinical information and the PROMIS-Pediatric-25. The floor and ceiling effect was examined. Cronbach's alpha and split-half coefficient were examined to determine the reliability. Factor structure was explored by factor analysis. Three assumptions of Rasch model-based item response theory (IRT) were assessed. Differential item functioning (DIF) was investigated concerning factors of gender, diagnosis, and treatment stage.

RESULTS

The floor or ceiling effects were detected for six domains. The reliability was found to be excellent. Furthermore, the factor structure of these six domains was validated. Our analysis confirmed that the assumptions required for IRT were met with acceptable unidimensionality, local independence, and good monotonicity. Additionally, we observed measurement equivalence, with outstanding levels of DIF across factors such as gender, diagnosis, and treatment stage.

CONCLUSION

PROMIS-Pediatric 25 is a highly reliable and valid instrument for evaluating key domains of health-related quality of life in Chinese pediatric cancer patients.

PRACTICE IMPLICATION

Nursing practice could engage the PROMIS-Pediatric 25 for accurate and quick children symptom and function assessment.

Functional Independence of Children With Arthrogryposis

BACKGROUND

Arthrogryposis (AMC) is a descriptive term to characterize a child born with multiple joint contractures. Treatment aims to improve functional independence, yet the literature objectively describing functional independence in this population is scarce. This study aimed to describe the functional independence of children with AMC through the lens of the Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT) and observational activities of daily living (ADL) tasks.

METHODS

Patients with AMC between the ages of 3 and 12 years participated in this prospective study. Parents completed the PEDI-CAT while a trained occupational therapist observed children as they completed a checklist of functional ADL tasks. Patients were grouped according to developmental age groups: "preschoolers" (3 to 5 y), "early school-age" (6 to 9 y), and "late school-age" (10 to 12 y). Patient's PEDI-CAT normative scores were described, comparing the study population to typically developing children, and differences in each domain were examined between developmental age groups. The observed ADL tasks completed were also described, and differences in scores were examined between developmental age groups.

RESULTS

Forty-four patients (mean age of 7±2.86 y) were enrolled. The distribution between age groups was nearly even. Mean daily activities T -score for patients with AMC was 25.80±11.98 and the mean mobility T -score was 17.39±9.77. Late school-age children scored significantly lower than preschool-age children in both of these domains ( P <0.01). Observed ADL tasks demonstrated a high level of required assistance for patients (range: 27.3% to 61.4%), although older school-age children did show greater independence with tested activities than preschool-age children ( P =0.05).

CONCLUSION

Children with AMC are significantly limited in functional independence, particularly regarding age-appropriate daily activities and mobility. Outcomes from this study provide a reference to help gauge the results of nonoperative and surgical treatment toward improving functional independence in this population.

Reducing Stress after Trauma (ReSeT): study protocol for a randomized, controlled trial of an online psychoeducational program and video therapy sessions for children hospitalized after trauma

BACKGROUND

Post-traumatic stress symptoms develop in a quarter to half of injured children affecting their longer-term psychologic and physical health. Evidence-based care exists for post-traumatic stress; however, it is not readily available in some communities. We have developed an eHealth program consisting of online, interactive educational modules and telehealth therapist support based in trauma-focused cognitive behavioral therapy, the Reducing Stress after Trauma (ReSeT) program. We hypothesize that children with post-traumatic stress who participate in ReSeT will have fewer symptoms compared to the usual care control group.

METHODS

This is a randomized controlled trial to test the effectiveness of the ReSeT intervention in reducing symptoms of post-traumatic stress compared to a usual care control group. One hundred and six children ages 8-17 years, who were admitted to hospital following an injury, with post-traumatic stress symptoms at 4 weeks post-injury, will be recruited and randomized from the four participating trauma centers. The outcomes compared across groups will be post-traumatic stress symptoms at 10 weeks (primary outcome) controlling for baseline symptoms and at 6 months post-randomization (secondary outcome).

DISCUSSION

ReSeT is an evidence-based program designed to reduce post-traumatic stress symptoms among injured children using an eHealth platform. Currently, the American College of Surgeons standards suggest that trauma programs identify and treat patients at high risk for mental health needs in the trauma system. If effectiveness is demonstrated, ReSeT could help increase access to evidence-based care for children with post-traumatic stress within the trauma system.

Challenges and Opportunities for the Use of Patient-Reported Outcome Measures in Orthopaedic Pediatric and Sports Medicine Surgery

Patient-reported outcome measures (PROMs) are essential tools in assessing treatment response, informing clinical decision making, driving healthcare policy, and providing important prognostic data regarding patient health status change. These tools become essential in orthopaedic disciplines, such as pediatrics and sports medicine, given the diversity of patient populations and procedures. However, the creation and routine administration of standard PROMs alone do not suffice to appropriately facilitate the aforementioned functions. Indeed, both the interpretation and optimal application of PROMs are essential to provide to achieve greatest clinical benefit. Contemporary developments and technologies surrounding PROMs may help augment this benefit, including the application of artificial intelligence, novel PROM structure with improved interpretability and validity, and PROM delivery methods that provide increased access to patients resulting in greater compliance and data acquisition yields. Despite these exciting innovations, several challenges remain in this realm that must be addressed to continue to advance the clinical usefulness and subsequent benefit of PROMs. This review will highlight the opportunities and challenges surrounding contemporary PROM use in the orthopaedic subspecialties of pediatrics and sports medicine.

Natural History of Pediatric Hand and Wrist Ganglion Cysts: Longitudinal Follow-Up of a Prospective, Dual-Center Cohort

PURPOSE

This investigation describes the outcomes of pediatric ganglion cysts in a prospective cohort that elected not to undergo cyst aspiration or surgical treatment. Our primary aim was to investigate the rate of spontaneous resolution over time among the subset of patients who did not undergo specific treatments.

METHODS

Children (aged ≤18 years) who presented to the clinic with ganglion cysts of the hand or wrist were enrolled in a prospective two-center registry between 2017 and 2021. Enrolled subjects who never elected to undergo cyst aspiration or surgical treatment were analyzed. The data collected included age, sex, cyst location and laterality, hand dominance, Wong-Baker pain scale scores, and Patient-Reported Outcome Measurement Information System upper-extremity scores. Follow-up surveys were completed for up to 5 years.

RESULTS

A total of 157 cysts in 154 children, with an average age of 9.4 years and a female-to-male ratio of 1.4:1, were eligible. The most common ganglion location was dorsal wrist (67/157, 42.7%), followed by volar wrist (49/157, 31.2%), the flexor tendon sheath (29/157, 18.5%), and the extensor tendon synovial lining (8/157, 5.1%). The average follow-up duration was 2.5 years after initial presentation to the clinic, and 63.1% (99/157) of the patients responded to follow-up surveys. Among them, 62.6% (62/99) of cysts spontaneously resolved; the resolution rates ranged from 51.9% of volar wrist ganglions to 81% of flexor tendon sheath cysts, with an average time to resolution of 14.1 months after cyst presentation. Cysts were more likely to resolve in the hand than in the wrist (84.0% vs 55.4%, respectively). Cysts present for >12 months at initial evaluation were less likely to resolve spontaneously (41.2% vs 67.1%).

CONCLUSIONS

Of children who elected not to undergo aspiration or surgical treatment, approximately two-thirds of families reported that their child's ganglion cyst resolved spontaneously. Cysts that resolve spontaneously usually do so within 2 years of presentation.

Validation of the simplified Chinese version of PROMIS Parent Proxy-25 Profile in parents of children with cancer

PURPOSE

To determine the psychometric properties of the Patient-reported Outcomes Measurement Information System Parent Proxy-25 Profile (PROMIS-25) in a sample of Chinese parents of children with cancer.

DESIGN AND METHODS

A cross-sectional sample (N = 148) of parents with children aged 5-17 years living with cancer was recruited. Each participant completed sociodemographic and clinical questionnaires and PROMIS-25. The flooring and ceiling effects were calculated. Reliability was determined by the Cronbach's alpha and split-half coefficient. Factor structure was examined by factor analysis. Model fit and graphical plots were assessed to test the assumptions of Rasch model-based item response theory (IRT). Differential item functioning (DIF) was assessed in terms of gender, age, and treatment stage.

RESULTS

PROMIS-25 demonstrated some flooring and ceiling effect, excellent reliability (Cronbach's α > 0.7 for all six domains), and the six-domain factor structure was supported. The IRT assumptions were met in terms of unidimensionality, local independence, monotonicity, and measurement equivalence with acceptable DIF in terms of gender, age, diagnosis, and treatment stage.

CONCLUSION

PROMIS-25 is a highly reliable and valid instrument for evaluating children with cancer that assesses important health-related quality of life domains of child cancer.

PRACTICE IMPLICATION

Chinese parents of children with cancer and healthcare providers could use PROMIS-25 to assess the symptoms of children.

Chronic pain interference assessment tools for children and adults who are unable to self-report: A systematic review of psychometric properties

AIM

To identify and evaluate psychometric properties of assessment tools for assessing pain interference in children, adolescents, and adults with chronic pain and the inability to self-report.

METHOD

The protocol was registered with PROSPERO (CRD42022310102). A search was run in MEDLINE, Embase, and PsycInfo (29th March 2022) to identify articles reporting psychometric properties of pain interference assessment tools for children, adolescents, and adults with chronic pain and the inability to objectively self-report pain. Retrieved studies were reviewed by two authors (MGS, LCF) and study quality was assessed using COSMIN.

RESULTS

Psychometric properties of 10 pain interference tools were assessed from 33 studies. The Paediatric Pain Profile (PPP) had low-quality evidence for content validity and internal consistency with children and adolescents who are unable to self-report. No tools for adults had evidence for content validity and internal consistency. No tool had evidence for all nine psychometric properties.

INTERPRETATION

The PPP is recommended for pain interference assessment in children and adolescents with chronic pain and the inability to self-report. Few tools are available for adults. Three tools for children (Patient-Reported Outcome Measurement Information System Pediatric Proxy Pain Interference Scale; Bath Adolescent Pain Questionnaire for Parents; modified Brief Pain Inventory-Proxy [mBPI]) and three tools for adults (Doloplus-2; Patient-Reported Outcome Measurement Information System Pain Interference Scale-proxy; Brief Pain Inventory-proxy) are promising but require further investigation.

Patient-Reported Outcome Measurement and Minimal Clinically Important Difference for Hand Surgeons

Patient-reported outcome measurement (PROM) tools are used to evaluate health status and response to treatment and have been integral in the effort to improve the quality of care provided. Patient reported outcomes (PROs) have garnered additional attention since becoming a priority of the National Institutes of Health in the early part of this century, and their use in both clinical practice and research has subsequently increased. In the upper extremity, a variety of PRO instruments exist that can assist physicians in their ability to track and/or prognosticate outcomes, make comparisons between treatments as well as strengthen research methodologies, and help determine the value of care. A more complete interpretation of the clinical significance of patient-reported outcome measurements is informed by parameters such as minimal clinically important difference, substantial clinical benefit and patient acceptable symptom state.

Relations among parent-reported physical activity and interoception in children

BACKGROUND

Interoception is the sense of one's internal body and emotional state; it plays a critical role in guiding self-regulatory behaviors. Physical activity (PA) can support interoceptive processes, but limited research has examined the association in children. This study explored the relations among parent-reported PA and several interoceptive domains in children aged 3 - 10 years old.

METHODS

Baseline data were analyzed from a cluster-randomized controlled study examining a yoga intervention (N = 122). Parents completed a questionnaire that included the Caregiver Questionnaire for Interoceptive Awareness, Second Edition (CQIA-2) and two measures of PA, the PROMIS Parent-Proxy Short Form (PROMIS-PA) and the adapted Burdette Proxy Report (aBPR-PA). Psychometrics of the CQIA-2 subscales were assessed and then used in subsequent analyses to examine the association between PA and interoceptive sensibility.

RESULTS

Seventy percent of the surveys were completed by mothers (30% by fathers), and their children (56% female, M_age = 5.81 ± 1.7 years) were predominately white. Across all children, PA had a significant positive relationship with interoceptive domains related to emotion and physical energy (p < 0.01). Children who met the PROMIS-PA "good" cutoff had a clearer sense of emotion and physical energy (F(2,115) = 4.30, p = 0.016, R² = 0.070), compared to children who did not. Children's age predicted interoceptive sensibility of illness and toileting needs (F(1,116) = 14.16, p < 0.001, R² = 0.109).

CONCLUSION

Children with higher PA levels were perceived to have better interoceptive sensibility of emotion and physical energy. Children's age was predictive of interoceptive domains representing the awareness of illness and toileting needs. Future work should consider incorporating direct measures of PA and child-reported interoceptive sensibility. A better understanding of their relationship will likely help guide the design of more effective interventions for health behavior development.

PROMIS Utilization in Pediatric Orthopaedics: A Scoping Review

BACKGROUND

The lack of a common patient-reported outcome metric used among the orthopaedic population is a problem that has been previously identified by the American Academy of Orthopaedic Surgeons. The Patient-Reported Outcomes Measurement Information System (PROMIS) was developed by the National Institute of Health with the goal of creating a precise and efficient measurement tool for patient-reported symptoms, functioning, and health-related quality of life to be used in clinical research. A study summarizing its use in the pediatric orthopaedic population has not been previously performed.

METHODS

We performed a literature search of Ovid Medline, Embase, Scopus, and the Cochrane Central Register of Controlled Trials from 2010 to August 2021. There were 1961 unique citations included after the removal of 1756 duplicates. After initial screening, 183 studies were screened under full-text review leaving a final number of 51 studies included in this scoping review.

RESULTS

Pediatric PROMIS studies were grouped by body part or sub-speciality: "Hand and Upper Extremity" (25.5%, n=13), "Sports" (23.5%, n=12), "Spine" (13.7%, n=7), "Trauma" (13.7%, n=7), "General Pediatric Orthopaedics" (11.8%, n=6), "Lower Extremity" (9.8%, n=5), and "Orthopaedic Oncology" (2%, n=1). An increase in studies utilizing PROMIS was seen throughout the study period with only 3 studies published from 2013 to 2016 to 39 in 2020 and 2021 alone. The 3 most frequently used pediatric PROMIS domains were Pain Interference (76.5%, n=39/51), Mobility (60.8%, n=31/51), and Upper Extremity (54.9%, n=28/51). 64.3% (n=9/14) of the included studies which reported on the floor effects of Pain Interference exhibited a significant floor effect. In all, 77.8% (n=7/9) of the included studies which reported on ceiling effects of Upper Extremity exhibited a significant ceiling effect.

CONCLUSION

The use of PROMIS increased significantly since the first publication in 2013 suggesting orthopaedic providers have increasingly utilized PROMIS in their day-to-day practice as an outcome measure. Ceiling and floor effects were prominent in several of the included domains (Pain Interference and Upper Extremity). Overall, PROMIS measures are efficient, reliable, and effective to use.

Patient-reported Outcomes for Children With Unilateral Congenital Below Elbow Deficiency

BACKGROUND

The Patient Reported Outcomes Measurement Information System (PROMIS ® ) is a validated tool used to evaluate different domains of function in patients with chronic health conditions. This tool has not been validated in children with unilateral congenital below elbow deficiency (UCBED). The purpose of this study was to determine whether PROMIS discerns functional impairment for children with UCBED and whether children with UCBED differ from the general population with respect to PROMIS outcomes. We hypothesized that children with UCBED report mild impairment in upper extremity function but normal mobility, pain interference and peer relations.

METHODS

A retrospective chart review of children aged 5 to 17 years with a diagnosis of UCBED who completed a PROMIS questionnaire at their clinic visit at the [blinded locations] was conducted between April 1, 2017 and March 31, 2020. The mean PROMIS scores of UCBED patients were compared with that of the general reference population. Mann Whitney and ANOVA tests were used to explore the differences across the PROMIS upper extremity function domain by arm length and prosthesis use.

RESULTS

Fifty-five children (28 boys) with a mean age of 11±3.6 years met the inclusion criteria. Children with UCBED had similar PROMIS scores as the reference population in mobility (51.9±6.2), peer relations (53.5±9.4), and pain interference (40.1±7.2), with mild impairment in the upper extremity function (44.3±10.7). Compared with the 8 to 17-year-old cohort, the parent-proxy (5 to 7-year-old group) reported significantly more upper extremity function impairment (31.3±5.9) vs (48.0±8.8) ( P =0.000). The two age groups did not differ with respect to mobility, pain interference and peer relations.

CONCLUSIONS

Our study confirms previous findings that children with UCBED report upper extremity function, peer relationships, pain interference, and mobility, similar to the reference population. In addition, parents of younger children with UCBED report more upper extremity functional impairment than is self-reported by older children with UCBED.

Translation and linguistic validation of the DISABKIDS chronic generic module into simplified Chinese (DCGM-37) for use among children with cancer

PURPOSE

To develop a simplified Chinese version of the DISABKIDS chronic generic module-37 (DCGM-37), and to test the translated measures in children with cancer by employing a cognitive interviewing technique.

DESIGN AND METHODS

The English version of DCGM-37 was translated forward and backward into simplified Chinese by bilingual translators, following the guidelines from its copyright holders, which also involved a cultural adaptation component. Twelve Chinese children aged 8-18 years and eight parents were cognitively interviewed.

RESULTS

The findings support the relevance, comprehensibility, and efficacy of the Chinese version. Consideration was given, and improvements were made, to the language, cultural concerns, and content, which improved functionality and increased validation. The patients/caregivers understood the instructions, questions, and answer choices. Some revisions, however, were made to address patient/caregiver feedback obtained through cognitive interviews. Conceptually and semantically, the simplified Chinese version of the DCGM-37 version was identical to the original. Conclusions The simplified Chinese version of the DCGM-37 was semantically and conceptually equivalent to the English version. Chinese children aged 8 to 18 years were able to comprehend this instrument.

CONCLUSIONS

The simplified Chinese version of the DCGM-37 was semantically and conceptually equivalent to the English version. Chinese children aged 8 to 18 years were able to comprehend this instrument and express their experiences and feelings about their life.

PRACTICE IMPLICATIONS

The simplified Chinese version of the DCGM-37 was translated, and cross-cultural adaptation and validation were performed. Chinese children found the tool easy to use and were able to express their experiences and feelings about their health-related quality of life.

Moderate Weightbearing Restrictions Are Associated with Worse Depressive Symptoms and Anxiety in Children Aged 5 to 7 Years with Perthes Disease

BACKGROUND

Perthes disease most commonly affects children 5 to 7 years old, and nonoperative management, such as weightbearing and activity restrictions, is generally recommended. In earlier research in children aged 8 to 14 years who had Perthes disease, we found that the restrictions were associated with worse mobility, but mental health or social health measures were not linked. However, Perthes disease most commonly affects children 5 to 7 years old who are more emotionally and cognitively immature. Children in this age group are beginning school and organized sports experiences while developing meaningful social relationships for the first time. Because of such different life experiences, it is important to understand the psychosocial consequences of weightbearing and activity restrictions on this specific age group, as they may help guide choices about weightbearing restrictions and mental health support.

QUESTIONS/PURPOSES

In patients aged 5 to 7 years with Perthes disease, we asked: (1) Are weightbearing and activity restrictions associated with worse mental health, evaluated with the Patient-reported Outcome Measurement Information System (PROMIS) depressive symptoms, anxiety, and anger questionnaires? (2) Are weightbearing and activity restrictions associated with worse social health (PROMIS peer relationships measure)? (3) Are weightbearing and activity restrictions associated with worse physical health measures (PROMIS mobility, pain interference, and fatigue measures)? (4) What other factors are associated with mental, social, and physical health measures in these patients?

METHODS

Data were collected from 97 patients with a diagnosis of Perthes disease. Inclusion criteria were age 5 to 7 years at the time the PROMIS was completed, English-speaking patients and parents, in the active stage of Perthes disease (Waldenstrom Stages I, II, or III) who were recommended weightbearing and activity restrictions because of worsening hip pain, poor hip ROM, femoral head deformity, as a postoperative regimen, or if there was substantial femoral head involvement on MRI [23]. Based on their weightbearing and activity restriction regimen, patients were categorized into one of four activity restriction groups (no, mild, moderate, and severe restriction). The following pediatric parent-proxy PROMIS measures were obtained: depressive symptoms, anxiety, anger, peer relationships, mobility, pain interference, and fatigue. We excluded five patients who did not meet the inclusion criteria. Of the remaining 92 patients, 21 were in the no restriction group, 21 were in the mild restriction group, 28 were in the moderate restriction group, and 22 were in the severe restriction group at the time of PROMIS administration. ANOVA was used to compare differences between the mean PROMIS T-scores of these four groups. T-scores are computed from PROMIS survey responses, and a T-score of 50 represents the age-appropriate mean of the US population with an SD of 10. A higher T-score means more of that measure is being experienced and a lower score means less of that measure is being experienced. To address the possibility of confounding variables such as Waldenstrom stage, gender, age at diagnosis, and history of major surgery, we performed a multivariable analysis to compare the association of different weightbearing regimens and the seven PROMIS measures. This allowed us to answer the question of whether weightbearing and activity restrictions are associated with worse physical, mental, and social health measures in Perthes patients aged 5 to 7 years, while minimizing the possible confounding of the variables listed above.

RESULTS

After controlling for confounding variables such as Waldenstrom stage, gender, age at diagnosis, and history of major surgery, we found that moderate activity restriction was associated with worse depressive symptoms (β regression coefficient = 6 [95% CI 0.3 to 12]; p = 0.04) and anxiety (β = 8 [95% CI 1 to 15]; p = 0.02) T-scores than no restrictions. The mild (β = -7 [95% CI -12 to -1]; p = 0.02), moderate (β = -15 [95% CI -20 to -10]; p < 0.001), and severe (β = -23 [95% CI -28 to -18]; p < 0.001), restriction groups had worse mobility T-scores than the no restriction group. Weightbearing and activity restrictions were not associated with anger, peer relationships, pain interference, and fatigue measures. Waldenstrom Stage II disease was associated with worse pain interference than Waldenstrom Stage III (β = 7 [95% CI 0.4 to 13]; p = 0.04). A history of major surgery was associated with worse anger scores (β = 18 [95% CI 3 to 33]; p = 0.02). The child's gender and age at diagnosis had no association with any of the seven PROMIS measures.

CONCLUSION

Moderate weightbearing and activity restrictions are associated with worse depressive symptoms and anxiety in patients with Perthes disease aged 5 to 7 years, after controlling for Waldenstrom stage, gender, age at the time of diagnosis, and history of surgery. Considering the discoveries in this study and in our previous study, for patients 5 to 7 years old, we recommend that providers discuss the potential for mental health changes with moderate weightbearing restrictions with patients and their families. Furthermore, providers should monitor for worsening mental health symptoms at each follow-up visit and refer patients to a clinical child psychologist for support when appropriate. Future studies are needed to assess the effects of these restrictions on mental health over time and after patients are allowed to return to normal activities.

Incorporating patient-centered quality-of-life measures for outcome assessment after Chiari malformation type I decompression in a pediatric population: a pilot study

OBJECTIVE

Optimal management of pediatric Chiari malformation type I (CM-I) is much debated, chiefly due to the lack of validated tools for outcome assessment, with very few tools incorporating patient-centered measures of health-related quality of life (HRQOL). Although posterior fossa decompression (PFD) benefits a subset of patients, prediction of its impact across patients is challenging. The primary aim of this study was to investigate the role of patient-centered HRQOL measures in the assessment and prediction of outcomes after PFD.

METHODS

The authors collected HRQOL data from a cohort of 20 pediatric CM-I patients before and after PFD. The surveys included assessments of selected Patient-Reported Outcomes Measurement Information System (PROMIS) health domains and were used to generate the PROMIS preference (PROPr) score, which is a measure of HRQOL. PROMIS is a reliable standardized measure of HRQOL domains such as pain, fatigue, depression, and physical function, which are all relevant to CM-I. The authors then compared the PROPr scores with Chicago Chiari Outcome Scale (CCOS) scores derived from time-matched clinical documentation. Finally, the authors used the PROPr scores as an outcome measure to predict postsurgical HRQOL improvement at 1 year on the basis of patient demographic characteristics, comorbidities, and radiological and physical findings. The Wilcoxon signed-rank test, Mann-Whitney U-test, and Kendall's correlation were used for statistical analysis.

RESULTS

Aggregate analysis revealed improvement of pain severity after PFD (p = 0.007) in anatomical patterns characteristic of CM-I. Most PROMIS domain scores trended toward improvement after surgery, with anxiety and pain interference reaching statistical significance (p < 0.002 and p < 0.03, respectively). PROPr scores also significantly improved after PFD (p < 0.008). Of the baseline patient characteristics, preexisting scoliosis was the most accurate negative predictor of HRQOL improvement after PFD (median -0.095 vs 0.106, p < 0.001). A correlation with modest magnitude (Kendall's tau range 0.19-0.47) was detected between the patient-centered measures and CCOS score.

CONCLUSIONS

The authors observed moderate improvement of HRQOL, when measured using a modified panel of PROMIS question banks, in this pilot cohort of pediatric CM-I patients after PFD. Further investigations are necessary to validate this tool for children with CM-I and to determine whether these scores correlate with clinical and radiographic findings.

Development of a Parent-Reported Outcome Measure for Febrile Infants ≤60 Days Old

OBJECTIVE

We aimed to develop a parent-reported outcome measure for febrile infants 60 days or younger evaluated in the emergency department.

METHODS

We conducted a 3-part study: (1) individual, semistructured interviews with parents of febrile infants 60 days or younger to generate potential items for the measure; (2) expert review with pediatric emergency medicine physicians and member checking with parents, who rated each item's clarity and relevance using 4-point scales; and (3) cognitive interviews with a new sample of parents, who gave feedback and rated the measure's ease of use on a 4-point scale. The measure was iteratively revised during each part of the development process.

RESULTS

In part 1, we interviewed 24 parents of 21 infants. Interviews revealed several themes: parents' experiences with medical care, communication, and decision making; parents' emotions, particularly worry, fear, and stress; the infant's outcomes valued by parents; and the impact of the infant's illness on the family. From these themes, we identified 22 potential items for inclusion in the measure. In part 2, 10 items were revised for clarity based on feedback from physicians and parents, primarily under the domains of parents' emotions and the infant's outcomes. In part 3, we further revised the measure for clarity and added an item. The final measure included 23 items and was rated as excellent in its ease of use.

CONCLUSIONS

The 23-item parent-reported outcome measure includes the experiences and outcomes important to parents. Further studies are needed to evaluate the measure's psychometric properties.

A Study Protocol for the Management of Children With Juvenile Idiopathic Arthritis Based on ePROs

BACKGROUND

Juvenile idiopathic arthritis (JIA) is a common chronic rheumatic disease with no known cures, affecting children with the age of onset under 16 years. Patient-reported outcome (PRO) measures are an important basis for evaluating the impact of JIA and associated therapies, however, which is particular challenge in the pediatric setting. At present, no randomized controlled studies have investigated the effect and usability of ePROs symptom management for children with JIA.

METHODS

This longitudinal, randomized, controlled trial will be carried out at outpatient and pediatric wards of the Shanghai Children's Medical Center affiliated to Shanghai Jiao Tong University School of Medicine. A total of one hundred children with JIA diagnosed according to the International League of Associations for Rheumatology (ILAR) patients are randomized to receive individualized symptom management based on ePROs or routine management. The primary outcome is the mean C-Ped-PROMIS T-scores of patients in the ePROs-based group and the control group. The secondary outcomes are the trajectories of C-Ped-PROMIS T-scores and HRQOL scores, and changing relationship between them. Data were collected at 5 time points: at enrollment ("baseline") and at the time of follow-up visits scheduled at 1, 3, 6, and 12 months.

DISCUSSION

The findings are expected to conclude that the symptom management based on ePROs for children with JIA can improve the symptom of JIA, and it is a feasible and effective way to monitor and intervene children with JIA.

Pediatric lymphoma patients in Malawi present with poor health-related quality of life at diagnosis and improve throughout treatment and follow-up across all Pediatric PROMIS-25 domains

BACKGROUND

Patient-reportedoutcomes (PROs) that assess health-related quality of life (HRQoL) are increasingly important components of cancer care and research that are infrequently used in sub-Saharan Africa (SSA).

METHODS

We administered the Chichewa Pediatric Patient-Reported Outcome Measurement Information System Pediatric (PROMIS)-25 at diagnosis, active treatment, and follow-up among pediatric lymphoma patients in Lilongwe, Malawi. Mean scores were calculated for the six PROMIS-25 HRQoL domains (Mobility, Anxiety, Depressive Symptoms, Fatigue, Peer Relationships, Pain Interference). Differences in HRQoL throughout treatment were compared using the minimally important difference (MID) and an ANOVA analysis. Kaplan-Meier survival estimates and Cox hazard ratios for mortality are reported.

RESULTS

Seventy-five children completed PROMIS-25 surveys at diagnosis, 35 (47%) during active treatment, and 24 (32%) at follow-up. The majority of patients died (n = 37, 49%) or were lost to follow-up (n = 6, 8%). Most (n = 51, 68%) were male, median age was 10 (interquartile range [IQR] 8-12), 48/73 (66%) presented with advanced stage III/IV, 61 (81%) were diagnosed with Burkitt lymphoma and 14 (19%) Hodgkin lymphoma. At diagnosis, HRQoL was poor across all domains, except for Peer Relationships. Improvements in HRQoL during active treatment and follow-up exceeded the MID. On exploratory analysis, fair-poor PROMIS Mobility <40 and severe Pain Intensity = 10 at diagnosis were associated with increased mortality risk and worse survival, but were not statistically significant.

CONCLUSIONS

Pediatric lymphoma patients in Malawi present with poor HRQoL that improves throughout treatment and survivorship. Baseline PROMIS scores may provide important prognostic information. PROs offer an opportunity to include patient voices and prioritize holistic patient-centered care in low-resource settings.

Anxiety and Depressive Symptoms in Juvenile Idiopathic Arthritis Correlate with Pain and Stress Using PROMIS Measures

OBJECTIVE

Describe anxiety and depressive symptoms in children with juvenile idiopathic arthritis (JIA) using Patient-Reported Outcome Measurement Information System (PROMIS) measures and evaluate potential correlations with disease manifestations.

METHODS

We performed a cross-sectional study of children with JIA and a parent-proxy who completed PROMIS measures on depression, anxiety, stress, and pain. The Childhood Health Assessment Questionnaire (CHAQ) measured mobility, and the clinical juvenile arthritis disease activity score (cJADAS10) measured disease activity.

RESULTS

84 patients completed the study. Demographic median values included: age 14 years, disease duration 4.73 years, CHAQ score 0, total active joint count 0, and cJADAS10 score 2. Using cJADAS10, 57 patients (68%) had inactive or low disease activity. Mean PROMIS T-scores for depressive and anxiety symptoms were lower in children with JIA compared to the reference population (p<0.0001). Nineteen patients (23%) had moderate to severe symptoms of anxiety and/or depression. Age and CHAQ score (mobility) correlated with depressive symptoms (r=0.36, p=0.0008; r=0.32, p=0.0029, respectively) but not anxiety. Depressive and anxiety symptoms correlated with pain (r=0.64 and r=0.47 respectively; p<0.0001) and stress (r=0.79 and r=0.75 respectively; p<0.0001) but not with gender, JIA subtype, disease duration, or disease activity.

CONCLUSION

Approximately one-quarter of children with JIA reported moderate to severe symptoms of anxiety and depression. These symptoms are associated with pain and stress, but they are not associated with other disease manifestations. Understanding how mental health symptoms and JIA impact one another is necessary in order to improve patient outcomes and provide well-rounded care.

Patient-reported Outcomes Measurement Information System (PROMIS) Scores for Children With Brachial Plexus Birth Injury

BACKGROUND

Patient-reported Outcomes Measurement Information System (PROMIS) for pediatrics is a validated patient-reported or parent-proxy-reported outcomes assessment tool used to evaluate health-related quality of life in children and adolescents with chronic medical conditions. The health-related quality of life of children with brachial plexus birth injury (BPBI) as measured by PROMIS is not well understood. We hypothesized that children with BPBI would report impaired upper extremity (UE) function but normal mobility, pain interference, and peer relationships compared with a reference pediatric population, and that UE function PROMIS scores would be associated with BPBI severity and patient age.

METHODS

This is a retrospective cohort study of 180 children with BPBI ages 5 to 17 years old who responded to 4 pediatric PROMIS domains (mobility, pain interference, peer relationships, and UE function) between April 2017 and April 2019. Responses were converted to a T score, which allows comparison with a reference pediatric population (mean reference score=50). Multivariable linear regression was used to quantify the association between PROMIS scores and age, sex, Narakas type, and composite Mallet score.

RESULTS

Children with BPBI had normal PROMIS mobility (49.6±8.5), pain interference (44.6±9.7), and peer relationships (52.4±10.6) scores, but reported mild impairment in UE function (40.8±12.1). Age (P<0.0001) and Narakas type (P=0.02) were associated with PROMIS UE function scores, but sex and composite Mallet scores were not. There were no significant associations between the other PROMIS domains and age, sex, Narakas Type, or composite Mallet scores.

CONCLUSIONS

Children with BPBI reported PROMIS scores for mobility, pain interference, and peer relationships similar to the reference population but impairment in UE function. Reported UE function decreased with increasing disease severity and increased with age. These PROMIS domains seem to be useful tools for the clinician to evaluate children with BPBI and better understand the challenges they face. Further study is needed to assess their utility in measuring the effects of treatment interventions.

Outcomes of Pediatric and Adolescent Carpal Tunnel Release

PURPOSE

To investigate carpal tunnel syndrome (CTS) presentation and long-term outcomes of carpal tunnel release (CTR) in children and adolescents.

METHODS

All pediatric and adolescent patients who underwent CTR between February 2003 and June 2018 were identified. Patients were grouped by etiology: lysosomal storage disease (11 hands), idiopathic (6 hands), acute traumatic (7 hands), delayed traumatic (5 hands) and tumorous (2 hands). Medical records were reviewed for presenting symptoms and preoperative treatments. Final outcomes were assessed via phone interviews, chart review, the Boston Carpal Tunnel Questionnaire (BCTQ), and Patient-Reported Outcomes Measurement Information System (PROMIS) scores.

RESULTS

All 25 patients (31 hands) identified were included in the study; median age at surgery was 12.7 years (range, 2.5-23.3 years). Eighteen patients completed surveys at a median of 4.7 years after surgery (range, 8 months-16 years). Common presenting symptoms in lysosomal storage disease were numbness/tingling (7 hands); pain was only reported in 1 hand. The most frequent indication for acute traumatic CTR (7 hands) was palmar hand swelling at the carpal tunnel (4 hands). Delayed traumatic and idiopathic CTS most often presented with numbness/tingling (4 hands and 6 hands, respectively) and pain (3 hands, 4 hands, respectively). Of the original 4 lysosomal storage disease surgeries included in long-term follow-up, all experienced gradual recurrence of symptoms after years of relief (range, 3-14 years). Two patients underwent revision CTR and were symptom-free at follow-up. All patients with acute traumatic and tumorous etiologies had full resolution of symptoms. Delayed traumatic and idiopathic etiologies frequently experienced recurrent or recalcitrant symptoms (4 of 5 and 3 of 6 surgeries, respectively).

CONCLUSIONS

Carpal tunnel release often alleviates symptoms in children with lysosomal storage disease for years to decades. Carpal tunnel release successfully relieves symptoms in acute traumatic cases, but is not always sufficient to relieve symptoms associated with delayed traumatic etiologies. Approximately half of patients with idiopathic CTS experience recalcitrant or recurrent symptoms.

Considerations to Support Use of Patient-Reported Outcomes Measurement Information System Pediatric Measures in Ambulatory Clinics

OBJECTIVE

To identify challenges to the use of Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric measures in the ambulatory pediatric setting and possible solutions to these challenges.

STUDY DESIGN

Eighteen semistructured telephone interviews of health system leaders, measurement implementers, and ambulatory pediatric clinicians were conducted. Five coders used applied thematic analysis to iteratively identify and refine themes in interview data.

RESULTS

Most interviewees had roles in leadership or the implementation of patient-centered outcomes; 39% were clinicians. Some had experience using PROMIS clinically (44%) and 6% were considering this use. Analyses yielded 6 themes: (1) selection of PROMIS measures, (2) method of administration, (3) use of PROMIS Parent Proxy measures, (4) privacy and confidentiality of PROMIS responses, (5) interpretation of PROMIS scores, and (6) using PROMIS scores clinically. Within the themes, interviewees illuminated specific unique considerations for using PROMIS with children, including care transitions and privacy.

CONCLUSIONS

Real-world challenges continue to hamper PROMIS use. Ongoing efforts to disseminate information about the integration of PROMIS measures in clinical care is critical to impacting the health of children.

Social Deprivation and Congenital Upper Extremity Differences-An Assessment Using PROMIS

PURPOSE

Social deprivation, a measure of socioeconomic status, has been shown to negatively affect perceptions of orthopedic conditions and outcomes of treatment. The objective of this study was to assess whether social deprivation correlates with subjective assessment of function in pediatric patients with congenital hand differences.

METHODS

Patients enrolled in the Congenital Upper Limb Differences (CoULD) registry were assessed using the Patient-Reported Outcomes Measurement Information System (PROMIS). The PROMIS scores for Pain Interference, Peer Relations, Anxiety, Depression, and Upper Extremity (UE) function were obtained for all patients 5 years and older at initial presentation. Social deprivation was determined by the Area Deprivation Index (ADI); the index ranges from 0 to 100 with higher scores being the most deprived. The PROMIS scores were correlated with the ADI for all patients.

RESULTS

Three hundred seventy-five pediatric patients with congenital UE differences were evaluated. Average age was 11 years, 56% were female, and 55% had bilateral involvement. Overall, PROMIS scores were within 1 SD of normal for Peer Relations, Pain, Depression, and Anxiety. However, child-reported scores for UE function (39) were more than 1 SD below the national average (50). The mean ADI for the cohort was lower than the national average, indicative of less deprivation, with 14% of patients in the most deprived national quartile. Children in the highest ADI quartile reported PROMIS scores that reflected higher Pain Interference (41 vs 45), lower Peer Relations (55 vs 50), higher Anxiety (44 vs 49), and higher Depression (43 vs 47) than children in the lowest ADI quartile.

CONCLUSIONS

The PROMIS scores were normal for psychosocial measures in children with congenital hand differences when evaluated as an entire cohort. However, child self-reported PROMIS scores for Pain Interference, Peer Relations, Anxiety, and Depression were worse in more socially deprived areas, suggesting more psychosocial challenges in these children.

CLINICAL RELEVANCE

Pediatric patients with congenital upper extremity differences in areas of higher social deprivation report lower psychosocial well-being. The care of these individuals must be considered within the context of their environment because they may be more at risk for negative outcomes secondary to environmental and societal stressors.

Validation of the caregiver Pediatric Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events measure

BACKGROUND

Despite improvements in survival rates, cancer treatments have significant side effects that affect the quality of life of children and their families. When an ill child cannot self-report symptoms (eg, he or she is too ill), caregiver (parent) reporting becomes critical. This study evaluates the validity and reliability of the caregiver-reported Pediatric Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (Ped-PRO-CTCAE [Caregiver]) measure.

METHODS

A diverse sample of caregivers with children receiving treatment at 9 oncology centers completed the Ped-PRO-CTCAE [Caregiver] measure, the Patient-Reported Outcomes Measurement Information System^® (PROMIS^® ) Parent Proxy measures, the Lansky Play-Performance Scale (PPS), medication use questions, and Global Impressions of Change (GIC). Construct validity (including convergent, discriminant, and known groups validity and responsiveness over time) and reliability (stability) were examined.

RESULTS

A majority of the 473 caregivers were female (85%), non-Hispanic White (61%), and married (75%). Symptoms assessed with the Ped-PRO-CTCAE [Caregiver] and PROMIS Parent Proxy measures were strongly correlated (e.g., r for pain = 0.78; r for fatigue = 0.78; and r for depression = 0.83). Most of the Ped-PRO-CTCAE [Caregiver] item mean scores distinguished among PPS function levels and between children who did take medications for symptom control and children who did not. Changes in Ped-PRO-CTCAE [Caregiver] item mean scores were responsive to GIC over time. Test-retest evaluation found moderate to high agreement (57.8%-93.3%) over time.

CONCLUSIONS

This study found strong evidence for the convergent and discriminant validity, known groups validity, responsiveness, and stability of the Ped-PRO-CTCAE [Caregiver] measure in a large and diverse sample of caregivers. The caregiver perspective provides a valuable and unique insight into the experiences of children and adolescents undergoing cancer treatment.

LAY SUMMARY

Despite advances in cancer treatments, children and adolescents continue to suffer from treatment side effects, including pain, nausea, fatigue, and emotional distress, that can adversely affect quality of life for children and their families. Although it is best for children to report how they are feeling, there are times when a child may be too young or too ill to self-report. This study provides critical evidence for a new type of questionnaire that allows the caregiver or parent to report accurately what the child is experiencing. This measure can be used to improve adverse event reporting and child cancer care.

The relationship between parental factors, child symptom profile, and persistent postoperative pain interference and analgesic use in children

OBJECTIVES

Both parental and child factors have been previously associated with persistent or recurrent postoperative pain in children. Yet, little is known about the relative contribution of parent factors or whether child symptom factors might impact the association between parent factors and long-term pain. The aim of this study was to explore the associations between parent factors, child symptomology, and the child's long-term pain outcomes after surgery.

METHODS

This prospective, longitudinal study included parents and their children who were scheduled to undergo spinal fusion for underlying scoliosis. Parents completed baseline surveys about their pain history, pain relief preferences (ie, preference to relieve their child's pain vs avoid analgesic risks), and pain catastrophizing (ie, beliefs about their child's pain). Children were classified previously into high vs low symptom profiles at baseline based on their self-reported pain, catastrophizing, fatigue, depression, and anxiety. Children were assessed 1-year after surgery for their long-term pain interference scores and analgesic use. Serial regression modeling was used to explore whether associations between parent factors and the outcomes were changed when accounting for child factors.

RESULTS

Seventy-six parent/child dyads completed all surveys. Parental preferences and catastrophizing were atemporally associated with the child's baseline psychological-somatic symptom profile. Though parent and child factors were both associated with the long-term pain outcomes, when all three factors were accounted for, the associations between parent factors and long-term pain was fully attenuated by the child's profile.

DISCUSSION

These findings suggest that the relationship between parent factors and long-term postoperative pain outcomes may be dependent on the child's symptom profile at baseline. Since there may be bidirectional relationships between parent and child factors, interventions to mitigate long-term pain should address child symptoms as well as parental factors.

Agreement Between Child Self-report and Caregiver-Proxy Report for Symptoms and Functioning of Children Undergoing Cancer Treatment

IMPORTANCE

Adult patients are considered the best reporters of their own health-related quality of life (HRQOL). Self-report in pediatrics has been challenged by a limited array of valid measures. Caregiver report is therefore often used as a proxy for child report.

OBJECTIVES

To examine the degree of alignment between child and caregiver proxy report for Patient-Reported Outcomes Measurement Information System (PROMIS) HRQOL domains among children with cancer and to identify factors associated with better child and caregiver-proxy congruence.

DESIGN, SETTING, AND PARTICIPANTS

In this multicenter cohort study, children with a first cancer diagnosis and their caregivers completed surveys at 2 time points: within 72 hours preceding treatment initiation (T1) and during follow-up (T2), when symptom burden was expected to be higher (eg, 7-17 days later for chemotherapy). Data were collected from October 26, 2016, to October 5, 2018, at 9 pediatric oncology hospitals. Five hundred eighty children (aged 7-18 years) and their caregivers were approached; 482 child-caregiver dyads completed surveys at T1 (response rate 83%), and 403 completed surveys at T2 (84% of T1 participants). Data were analyzed from July 1, 2019, to April 22, 2020.

EXPOSURES

Participants received up-front cancer treatment, including chemotherapy and radiotherapy.

MAIN OUTCOMES AND MEASURES

Congruence between child self-report and caregiver-proxy report of PROMIS pediatric domains of mobility (physical functioning), pain interference, fatigue, depressive symptoms, anxiety, and psychological stress.

RESULTS

Of the 482 dyads included in the analysis, 262 children (54%) were male (mean [SD] age, 12.9 [3.4] years), 80 (17%) were Black, and 71 (15%) were Hispanic. Intraclass correlations between child self-report and caregiver proxy report showed moderate agreement for mobility (0.57 [95% CI, 0.50-0.63]) and poor agreement for symptoms (range, 0.32 [95% CI, 0.24-0.41] for fatigue to 0.42 [95% CI, 0.34-0.50] for psychological stress). Children reported lower symptom burden and higher mobility than caregivers reported. In a multivariable model adjusted for child and parent sociodemographic factors and the caregiver's own self-reported HRQOL, caregivers reported the child's mobility score 6.00 points worse than the child's self-report at T2 (95% CI, -7.45 to -4.51), exceeding the PROMIS minimally important difference of 3 points. Caregivers overestimated the child's self-reported symptom levels, ranging from 5.79 (95% CI, 3.99-7.60) points for psychological stress to 13.69 (95% CI, 11.60-15.78) points for fatigue. The caregiver's own self-reported HRQOL was associated with the magnitude of difference between child and caregiver scores for all domains except mobility; for example, for fatigue, the magnitude of difference between child and caregiver-proxy scores increased by 0.21 (95% CI, 0.13-0.30) points for each 1-point increase in the caregiver's own fatigue score.

CONCLUSIONS AND RELEVANCE

This study found that caregivers consistently overestimated symptoms and underestimated mobility relative to the children themselves. These results suggest that elicitation of the child's own report should be pursued whenever possible.

Evaluating Multiple Domains of Health in High School Athletes With Sport-Related Concussion

CONTEXT

Concussions are shown to hinder multiple health dimensions, including health-related quality of life (HRQOL), suggesting a need for a whole-person approach to assessment and treatment. Patient-reported outcome measures are one method to gather the patient's perspective regarding their HRQOL.

OBJECTIVE

To evaluate perceived HRQOL using the Patient-Reported Outcomes Measurement Information System Pediatric-25 subscale in patients throughout concussion recovery.

DESIGN

Prospective cohort, descriptive survey.

SETTING

There were 9 high school athletic training facilities.

PARTICIPANTS

A total of 70 patients with diagnosed concussions (51 males, 7 females, 12 unreported; age = 15.7 [0.9] y, height = 174.6 [8.4] cm, mass = 72.8 [14.8] kg, grade = 10.0 [0.9] level).

INTERVENTIONS

Patient-Reported Outcomes Measurement Information System Pediatric-25 was administered at 3 days, 10 days postconcussion, and return to play (RTP).

MAIN OUTCOME MEASURES

Patient-Reported Outcomes Measurement Information System Pediatric-25 subscale T scores and self-reported concussion history (yes/no).

RESULTS

A total of 70 patients completed the study. For the Pediatric-25 subscales, the severity of problems associated with Physical Function Mobility, Anxiety, Depression, Fatigue, and Pain Interference were highest 3 days postconcussion, decreasing at 10 days and RTP (all p < .05). No differences were found between days 3 and 10 for Peer Relationship scores, but improvements were identified at RTP (p < .05). Pediatric-25 subscale scores at the 3 measurements were not statistically associated with concussion history (all p > .05). Ceiling and floor effects were present in all subscales throughout each timepoint, except for Physical Function Mobility (14.7%), and pain interference (11.8%) at day 3 postinjury.

CONCLUSIONS

Patients who had suffered a concussion improved from day 3 through RTP on multiple health domains as demonstrated through the Pediatric-25 subscales. These findings highlight the need for health care professionals to serially monitor HRQOL and social factors that may affect the patient postconcussion as part of a multifactorial assessment. Ceiling effects in high functioning adolescent athletes were present; thus, efforts should be made to identify appropriate scales for use in managing recovery in athletic populations.

Use of PROMIS in Assessment of Children With Ponseti-treated Idiopathic Clubfoot: Better Scores With Greater Than 3 Years of Brace Use

BACKGROUND

Patient-Reported Outcomes Measurement Information System (PROMIS) is a well-validated tool used to measure health-related quality of life for children and adolescents with chronic medical conditions. The current study evaluates PROMIS scores in 3 domains for children with Ponseti-treated idiopathic clubfoot.

METHODS

This is a retrospective cohort study of 77 children, ages 5 to 16 years, treated by Ponseti protocol for idiopathic clubfoot. Three pediatric PROMIS domains (Mobility, Pain Interference, and Peer Relationships) were administered between April 2017 and June 2018. One-way analysis of variance with Bonferroni post hoc and independent sample t tests were performed to explore differences across PROMIS domain scores by sex, age, initial Dimeglio score, laterality, bracing duration, and whether the child underwent tibialis anterior transfer.

RESULTS

In the self-reported group (ages 8 to 16), mean T-scores for all 3 domains in both unilaterally and bilaterally affected groups were within the normal range, with respect to the general reference pediatric population. However, children with unilateral clubfoot had a significantly higher mean Mobility T-score (54.77) than children with bilateral clubfoot (47.81, P=0.005). Children with unilateral clubfoot also had significantly lower mean pain scores (39.16) than their bilateral counterparts (46.56, P=0.005). Children who had braced >36 months had a significantly higher mean Mobility T-score (53.68) than children who braced ≤36 months (46.28, P=0.004).In the proxy group (ages 5 to 7), mean T-scores for all 3 domains in both laterality groups were within the normal range, with respect to the reference population. Children who had braced >36 months had a significantly higher mean Mobility T-score (52.75 vs. 49.15, P=0.014) and lower Pain Interference score (43.04 vs. 49.15, P=0.020) than children who braced ≤36 months.

CONCLUSIONS

Children treated by Ponseti protocol for idiopathic clubfoot yielded PROMIS scores for Mobility, Pain Interference, and Peer Relationships domains similar to the reference population. Bracing duration >36 months and unilaterality were associated with less mobility impairment than their counterparts. These findings may help guide parent recommendations.

Upper Extremity Function, Peer Relationships, and Pain Interference: Evaluating the Biopsychosocial Model in a Pediatric Hand Surgery Population Using PROMIS

PURPOSE

The relationship between biopsychosocial factors and patient-reported function is less clear in pediatric than in adult hand surgery patients. Our primary hypothesis was that pain interference (PI) and peer relationships (PR) would demonstrate association with upper extremity function. Secondarily, we hypothesized that the magnitude of this effect would increase with age.

METHODS

Patients aged 5 to 17 years presenting to a tertiary academic clinic between October 2017 and January 2019 were included. The parent/guardian was administered the following instruments after indicating they, rather than the patient, were answering the questions on a tablet computer: Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE) Parent Proxy (PP) Computer Adaptive Test (CAT) v2.0, PROMIS PI PP CAT v2.0, and the PROMIS PR PP CAT v2.0. Ceiling/floor effects and Spearman correlations were calculated. Multivariable Tobit modeling was performed to determine whether biopsychosocial factors and upper extremity function were associated. Multivariable regression coefficients were compared between age cohorts using a separate multivariable model to evaluate the interaction between age and other predictors.

RESULTS

Of 139 included participants, the mean age was 11.7 ± 3.7 years and 50% were female. For patients 11 years of age or younger, UE was weakly correlated with PI (coefficient, -0.34; 95% confidence interval, -0.56 to -0.08) and was not correlated with PR. For patients older than 11 years, UE had moderate correlation with PI (coefficient, -0.60; 95% confidence interval, -0.72 to -0.45) and was not correlated with PR. Multivariable analysis demonstrated a significant negative association between PI and UE, with a significantly larger magnitude of effect for patients older than 11 years of age.

CONCLUSIONS

The biopsychosocial model applies to pediatric hand surgery patients. The association between greater pain interference and worse patient-reported upper extremity function, as assessed using parent proxy instruments, was significantly stronger for patients older than 11 years than those 11 years old or younger.

CLINICAL RELEVANCE

This study suggests that the biopsychosocial model applies to pediatric hand patients.

Identifying clinically meaningful severity categories for PROMIS pediatric measures of anxiety, mobility, fatigue, and depressive symptoms in juvenile idiopathic arthritis and childhood-onset systemic lupus erythematosus

PURPOSE

A key limitation to widespread adoption of patient-reported outcome (PRO) measures is the lack of interpretability of scores. We aim to identify clinical severity thresholds to distinguish categories of no problems, mild, moderate, and severe along the PROMIS® Pediatric T-score metric for measures of anxiety, mobility, fatigue, and depressive symptoms for use in populations with juvenile idiopathic arthritis (JIA) and childhood-onset systemic lupus erythematosus (cSLE).

METHODS

We used a modified standard setting methodology from educational testing to identify clinical severity thresholds (clinical cut scores). Using item response theory-based parameters from PROMIS item banks, we developed a series of clinical vignettes that represented different severity or ability levels along the PROMIS Pediatric T-score metric. In stakeholder workshops, participants worked individually and together to reach consensus on clinical cut scores. Median cut-score placements were taken when consensus was not reached. Focus groups were recorded and qualitative analysis was conducted to identify decision-making processes.

RESULTS

Nine adolescents (age 13-17 years) with JIA (33% female) and their caregivers, five adolescents (age 14-16 years) with cSLE (100% female) and their caregivers, and 12 pediatric rheumatologists (75% female) participated in bookmarking workshops. Placement of thresholds for bookmarks was highly similar across stakeholder groups (differences from 0 to 5 points on the PROMIS t-score metric) for all but one bookmark placement.

CONCLUSION

This study resulted in clinical thresholds for severity categories for PROMIS Pediatric measures of anxiety, mobility, fatigue, and depressive symptoms, providing greater interpretability of scores in JIA and cSLE populations.

Performance of Pediatric PROMIS CATs in Children With Upper Extremity Fractures

Background: This study was designed to quantify the performance of the pediatric Patient-Reported Outcome Measurement Information System (PROMIS) when delivered as part of routine care to children with upper extremity (UE) fractures. Methods: This cross-sectional study analyzed 964 new pediatric patients presenting with an UE fracture. All patients completed PROMIS computer adaptive tests for pain interference, peer relationships, UE function, and mobility domains at clinic registration. PROMIS was completed by parent-proxy (n = 418) for 5- to 7-year-olds and self-reported by 8- to 10-year-olds (n = 546). PROMIS score distributions were defined, and Pearson correlations assessed the interrelation between PROMIS domains. Student's t tests compared mean PROMIS scores between parent-proxy and self-completion groups. Results: UE scores indicated the greatest average impairment of all PROMIS domains. However, 13% of patients reached the UE score ceiling indicating maximal UE function. UE scores and mobility scores had a strong positive correlation while UE scores had a moderate negative correlation with pain interference. In all patients, peer relationships were, at most, very weakly correlated with any other PROMIS domain. After grouping by fracture type, parent-proxy completion estimated worse UE function, more pain interference, and worse peer relationship. Conclusions: Pediatric PROMIS UE function scores capture impairment from UE fractures but do have a strong positive correlation with pediatric PROMIS Mobility, which assesses lower extremity function. Among children with UE fractures, parent-proxy completion of pediatric PROMIS appears associated with worse scores on most PROMIS domains.

Sleep Quality and Quality of Life Among Healthy High School Athletes

We examined the association between sleep quality and quality of life (QOL) among uninjured high school athletes. Participants completed the Pittsburgh Sleep Quality Index (PSQI) and the Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric Profile 25 questionnaire. One hundred ten athletes reported poor sleep quality (mean PSQI: 6.6 ± 2.0; mean age: 15.3 ± 1.1; 62% female); 162 athletes reported good sleep quality (mean PSQI: 2.3 ± 1.3; mean age: 15.1 ± 1.7; 33% female). After adjusting for sex and age, worse sleep quality was associated with higher physical function/mobility (β = 0.034; 95% confidence interval [CI] = 0.007-0.060; P = .01), anxiety (β= 0.391; 95% CI = 0.263-0.520; P < .001), depressive symptom (β = 0.456; 95% CI = 0.346-0.565; P < .001), fatigue (β = 0.537; 95% CI = 0.438-0.636; P < .001), pain interference (β = 0.247; 95% CI = 0.119-0.375; P < .001), and pain intensity (β = 0.103; 95% CI = 0.029-0.177; P = .006) ratings. Poor self-reported sleep quality among adolescent athletes was associated with worse QOL ratings. Clinicians should consider assessing sleep hygiene to provide guidance on issues pertaining to reduced QOL.

"Asking Too Much?": Randomized N-of-1 Trial Exploring Patient Preferences and Measurement Reactivity to Frequent Use of Remote Multidimensional Pain Assessments in Children and Young People With Juvenile Idiopathic Arthritis

Background

Remote monitoring of pain using multidimensional mobile health (mHealth) assessment tools is increasingly being adopted in research and care. This assessment method is valuable because it is challenging to capture pain histories, particularly in children and young people in diseases where pain patterns can be complex, such as juvenile idiopathic arthritis (JIA). With the growth of mHealth measures and more frequent assessment, it is important to explore patient preferences for the timing and frequency of administration of such tools and consider whether certain administrative patterns can directly impact on children’s pain experiences.

Objective

This study aimed to explore the feasibility and influence (in terms of objective and subjective measurement reactivity) of several time sampling strategies in remote multidimensional pain reporting.

Methods

An N-of-1 trial was conducted in a subset of children and young people with JIA and their parents recruited to a UK cohort study. Children were allocated to 1 of 4 groups. Each group followed a different schedule of completion of MPT for 8 consecutive weeks. Each schedule included 2 blocks, each comprising 4 different randomized time sampling strategies, with each strategy occurring once within each 4-week block. Children completed MPT according to time sampling strategies: once-a-day, twice-a-day, once-a-week, and as-and-when pain was experienced. Adherence to each strategy was calculated. Participants completed the Patient-Reported Outcomes Measurement Information System Pain Interference Scale at the end of each week to explore objective reactivity. Differences in pain interference scores between time sampling strategies were assessed graphically and using Friedman tests. Children and young people and their parents took part in a semistructured interview about their preferences for different time sampling strategies and to explore subjective reactivity.

Results

A total of 14 children and young people (aged 7-16 years) and their parents participated. Adherence to pain reporting was higher in less intense time sampling strategies (once-a-week=63% [15/24]) compared with more intense time sampling strategies (twice-a-day=37.8% [127/336]). There were no statistically significant differences in pain interference scores between sampling strategies. Qualitative findings from interviews suggested that children preferred once-a-day (6/14, 43%) and as-and-when pain reporting (6/14, 43%). Creating routine was one of the most important factors for successful reporting, while still ensuring that comprehensive information about recent pain was captured.

Conclusions

Once-a-day pain reporting provides rich contextual information. Although patients were less adherent to this preferred sampling strategy, once-a-day reporting still provides more frequent assessment opportunities compared with other less intense or overburdensome schedules. Important issues for the design of studies and care incorporating momentary assessment techniques were identified. We demonstrate that patient reporting preferences are key to accommodate and are important where data capture quality is key. Our findings support frequent administration of such tools, using daily reporting methods where possible.

Convergent Validity of PODCI and PROMIS Domains in Congenital Upper Limb Anomalies

PURPOSE

This study evaluates the perceived functional and psychosocial impact of upper limb congenital anomalies prior to surgical intervention, utilizing the Pediatric Outcomes Data Collection Instrument (PODCI) and Patient-Reported Outcomes Measure Information System (PROMIS) domains. We hypothesized that scores will be in the normal range and that the 2 outcomes measures will have strong convergent validity.

METHODS

A multicenter prospectively collected database of congenital upper limb patients, the CoULD (Congenital Upper Limb Differences) study group, was utilized. Demographic information was collected, and anomalies were classified by the Oberg-Manske-Tonkin (OMT) classification. Scores for PODCI subscales of Upper Extremity (UE) function, Pain/comfort, and Happiness and PROMIS domain of UE function, Pain, Depression, Anxiety, and Peer relations were collected. Ceiling and floor effects and convergent validity for PODCI and PROMIS domains were calculated.

RESULTS

Three hundred fifty-nine patients, average age 10 years and 55% male, were included. Two hundred forty-one patients had a malformation of the entire limb and 231 had a hand plate malformation. Four patients had a deformation, 118 dysplasia, and 45 a syndrome. There was no difference between the PODCI and the PROMIS ceiling or floor effects for the UE domains. The ceiling effect for PROMIS Pain domain (46%) was similar to the floor effect of the PODCI Pain subscale and no difference was seen between the floor effect of PODCI Happiness and PROMIS Depression domains. Convergent validity was obtained for the UE and Pain domains, and also between PODCI Happiness and PROMIS Depression subscales.

CONCLUSIONS

The PROMIS domains for UE function, Pain, and Depression are comparable with PODCI scores in congenital upper extremity anomalies.

CLINICAL RELEVANCE

Given the large burden placed on patients with the lengthy PODCI questionnaire, consideration of replacing the PODCI with the more quickly obtained PROMIS scores may reduce patient burden and provide similar information in this population.

Affective dysregulation in childhood - optimizing prevention and treatment: protocol of three randomized controlled trials in the ADOPT study

BACKGROUND

The terms affective dysregulation (AD) and irritability describe transdiagnostic dimensions and are characterized by an excessive reactivity to negative emotional stimuli with an affective (anger) and a behavioral component (aggression). Due to early onset, high prevalence and persistence, as well as developmental comorbidity, AD in childhood is one of the most psychosocially impairing and cost-intensive mental health conditions. AD is especially prevalent in children in the youth welfare service. Despite continuous research, there remains a substantial need for diagnostic approaches and optimization of individualized treatment strategies in order to improve outcomes and reduce the subjective and economic burden.

METHODS

The ADOPT (Affective Dysregulation - Optimizing Prevention and Treatment) Consortium integrates internationally established, highly experienced and interdisciplinary research groups. The work program encompasses (a) epidemiology, including prevalence of symptoms and disorders, (b) development and evaluation of screening and assessment tools, (c) stepped care approaches for clinically useful personalized medicine, (d) evaluation of an easily accessible and cost-effective online intervention as indicated prevention (treatment effects, moderation/mediation analysis), and (e) evaluation of an intensive personalized modular outpatient treatment in a cohort of children with AD who live with their parents and in a cohort of children with AD who live in out-of-home care (treatment effects, moderation/mediation analysis).

DISCUSSION

The results will lead to significant recommendations for improving treatment within routine clinical care in two cohorts of children with AD and coexisting conditions, especially oppositional-defiant disorder, conduct disorder and disruptive mood dysregulation disorder.

Local Anesthesia With General Anesthesia for Pediatric Bone Marrow Procedures

BACKGROUND

Pediatric patients with cancer undergo repeated painful procedures, including bone marrow aspirations and biopsies (BMABs). Optimal management of procedure-related pain can reduce discomfort, anxiety, and distress.

METHODS

Children with neuroblastoma were randomly assigned to 1 of 2 arms on a prospective, single-blind, crossover trial conducted at Memorial Sloan Kettering Cancer Center from October 2016 to January 2018 (www.clinicaltrials.gov, identifier NCT02924324). Participants underwent 2 sequential BMABs: one with general anesthesia (GA) alone, the other with GA plus local anesthesia (LA) (GA + LA). The objective was to assess procedure-related pain and its interference with quality of life (QoL) with GA versus GA + LA. Primary outcome was percentage of participants requiring postprocedural opioids. Secondary outcomes were total opioid and nonopioid analgesics, pain scores, time to first analgesic, QoL, and toxicity. Management of postprocedural pain was standardized.

RESULTS

Of 56 participants randomly assigned (3-16.5 years old), 46 completed both procedures. There was no significant difference in percentage of participants requiring opioids with GA versus GA + LA (24% vs 20%, P = .5). Pain scores in the recovery room were significantly lower for GA + LA versus GA (median [IQR]: 0 [0-2] vs 2 [0-4], P = .002). There were no statistically significant differences in total opioid or nonopioid analgesic, 6- and 24-hour pain scores, median time to first analgesic, or pain interference. No adverse events occurred.

CONCLUSIONS

LA was associated with significant improvement in pain scores in the immediate recovery period. LA did not reduce postprocedural opioid use, nor did it improve QoL for patients undergoing BMAB with GA.

Development of a parents' short form survey of their children's oral health

BACKGROUND

Parents play an important role in their children's oral health behaviors, provide oral health access, initiate prevention, and coping strategies for health care.

AIM

This paper develops a short form (SF) to assist parents to evaluate their children's oral health status using Patient-Reported Outcome Measurement Information System (PROMIS) framework that conceptualized health as physical, mental, and social components.

DESIGN

Surveys of parents were conducted at dental clinics in Los Angeles County, together with an on-site clinical examination by dentists to determine clinical outcomes, Children's Oral Health Status Index (COHSI), and referral recommendations (RRs). Graded response models in item response theory were used to create the SF. A toolkit including SF, demographic information, and algorithms was developed to predict the COHSI and RRs.

RESULTS

The final SF questionnaire consists of eight items. The square root mean squared error for the prediction of COHSI is 7.6. The sensitivity and specificity of using SF to predict immediate treatment needs (binary RRs) are 85% and 31%.

CONCLUSIONS

The parent SF is an additional component of the oral health evaluation toolkit that can be used for oral health screening, surveillance program, policy planning, and research of school-aged children and adolescents from guardian perspectives.

Translation, psychometric validation, and baseline results of the Patient-Reported Outcomes Measurement Information System (PROMIS) pediatric measures to assess health-related quality of life of patients with pediatric lymphoma in Malawi

INTRODUCTION

Internationally validated tools to measure patient-reported health-related quality of life (HRQoL) are available, but efforts to translate and culturally validate such tools in sub-Saharan Africa (SSA) are scarce, particularly among children.

METHODS

The Patient-Reported Outcomes Measurement Information System 25-item pediatric short form (PROMIS-25) assesses six HRQoL domains-mobility, anxiety, depression, fatigue, peer relationships, and pain interference-by asking four questions per domain. There is a single-item pain intensity item. The PROMIS-25 was translated into Chichewa and validated for use in Malawi using mixed qualitative and quantitative methods. The validity and reliability of the PROMIS-25 was assessed.

RESULTS

Fifty-four pediatric patients with lymphoma completed the PROMIS-25. Structural validity was supported by interitem correlations and principal component analysis. Reliability of each scale was satisfactory (range alpha = 0.71-0.93). Known group validity testing showed that anemic children had worse fatigue (P = 0.016) and children with poor performance status had worse mobility (P < 0.001) and pain interference (P = 0.005). Compared to children with cancer in the United States, children from Malawi reported lower levels of mobility, higher anxiety, higher depressive symptoms, higher fatigue, better satisfaction with peer relationships, and higher pain interference.

CONCLUSION

Translation and cultural validation of the PROMIS-25 into Chichewa for Malawi was successful. Baseline HRQoL for patients with pediatric lymphoma in Malawi is poor for all domains except peer relationships. This emphasizes an urgent need to address HRQoL among children undergoing cancer treatment in SSA using self-reported instruments validated within the local context.

The Impact of Social Deprivation on Pediatric PROMIS Health Scores After Upper Extremity Fracture

PURPOSE

Although social deprivation is acknowledged to influence physical and mental health in adults, it is unclear if and how social deprivation influences perceived health in children. This study was conducted to evaluate the impact of social deprivation on Patient-Reported Outcomes Measurement Information System (PROMIS) scores in children presenting for treatment of upper extremity fractures.

METHODS

This cross-sectional evaluation analyzed data from 975 new pediatric patients (8-17 years old) with upper extremity fractures presenting to a tertiary orthopedic center between June 1, 2016, and June 1, 2017. They completed self-administered PROMIS Computer Adaptive Tests (CATs). The Area Deprivation Index was used to quantify social deprivation. Bivariate statistical analysis determined the effect of disparate area deprivation (based on most and least deprived national quartiles) for the entire population.

RESULTS

A total of 327 children (34%) lived in areas categorized as the most socially deprived quartile of the United States, whereas 202 (21%) arrived from homes in the least socially deprived quartile. Children in the most deprived quartile had significantly worse mean PROMIS Upper Extremity Function, Mobility, Pain Interference, and Peer Relations scores than those in the least deprived quartile. Significantly more children from the most socially deprived areas were black. Patient age, sex, and fracture type were not significantly different between patients from the least and the most socially deprived quartiles.

CONCLUSIONS

Children living in areas of greatest social deprivation report worse Upper Extremity Function, Mobility, Pain Interference, and Peer Relations scores on self-administered PROMIS CATs than children from areas of least social deprivation at presentation for care of upper extremity fractures. The impact of social deprivation on perceived health and function is evident before adulthood and, therefore, interventions to mitigate this effect should be offered to children as well as adults.

TYPE OF STUDY/LEVEL OF EVIDENCE

Prognostic II.

Design of a pragmatic trial in minority children presenting to the emergency department with uncontrolled asthma: The CHICAGO Plan

Among children with asthma, black children are two to four times as likely to have an emergency department (ED) visit and die from asthma, respectively, compared to white children in the United States. Despite the availability of evidence-based asthma management guidelines, minority children are less likely than white children to receive or use effective options for asthma care. The CHICAGO Plan is a three-arm multi-center randomized pragmatic trial of children 5 to 11years old presenting to the ED with uncontrolled asthma that compares: [1] an ED-focused intervention to improve the quality of care on discharge to home, [2] the same ED-focused intervention together with a home-based community health worker (CHW)-led intervention, and [3] enhanced usual care. All children receive spacers for the metered dose inhaler and teaching about its use. The Patient-Reported Outcomes Measurement Information System (PROMIS) Asthma Impact Scale and Satisfaction with Participation in Social Roles at 6months are the primary outcomes in children and in caregivers, respectively. Other patient-reported outcomes and indicators of healthcare utilization are assessed as secondary outcomes. Innovative features of the CHICAGO Plan include early and continuous engagement of children, caregivers, the Chicago Department of Public Health, and other stakeholders to inform the design and implementation of the study and a shared research infrastructure to coordinate study activities. The objective of this report is to describe the development of the CHICAGO Plan, including the methods and rationale for engaging stakeholders, the shared research infrastructure, and other features of the pragmatic clinical trial design.

Establishing clinical meaning and defining important differences for Patient-Reported Outcomes Measurement Information System (PROMIS®) measures in juvenile idiopathic arthritis using standard setting with patients, parents, and providers

BACKGROUND

Patient-Reported Outcomes Measurement Information System (PROMIS) measures are used increasingly in clinical care. However, for juvenile idiopathic arthritis (JIA), scores lack a framework for interpretation of clinical severity, and minimally important differences (MID) have not been established, which are necessary to evaluate the importance of change.

METHODS

We identified clinical severity thresholds for pediatric PROMIS measures of mobility, upper extremity function (UE), fatigue, and pain interference working with adolescents with JIA, parents of JIA patients, and clinicians, using a standard setting methodology modified from educational testing. Item parameters were used to develop clinical vignettes across a range of symptom severity. Vignettes were ordered by severity, and panelists identified adjacent vignettes considered to represent upper and lower boundaries separating category cut-points (i.e., from none/mild problems to moderate/severe). To define MIDs, panelists reviewed a full score report for the vignettes and indicated which items would need to change and by how much to represent "just enough improvement to make a difference."

RESULTS

For fatigue and UE, cut-points among panels were within 0.5 SD of each other. For mobility and pain interference, cut-scores among panels were more divergent, with parents setting the lowest cut-scores for increasing severity. The size of MIDs varied by stakeholders (parents estimated largest, followed by patients, then clinicians). MIDs also varied by severity classification of the symptom.

CONCLUSIONS

We estimated clinically relevant severity cut-points and MIDs for PROMIS measures for JIA from the perspectives of multiple stakeholders and found notable differences in perspectives.

Modeling and Testing Differential Item Functioning in Unidimensional Binary Item Response Models with a Single Continuous Covariate: A Functional Data Analysis Approach

Differential item functioning (DIF), referring to between-group variation in item characteristics above and beyond the group-level disparity in the latent variable of interest, has long been regarded as an important item-level diagnostic. The presence of DIF impairs the fit of the single-group item response model being used, and calls for either model modification or item deletion in practice, depending on the mode of analysis. Methods for testing DIF with continuous covariates, rather than categorical grouping variables, have been developed; however, they are restrictive in parametric forms, and thus are not sufficiently flexible to describe complex interaction among latent variables and covariates. In the current study, we formulate the probability of endorsing each test item as a general bivariate function of a unidimensional latent trait and a single covariate, which is then approximated by a two-dimensional smoothing spline. The accuracy and precision of the proposed procedure is evaluated via Monte Carlo simulations. If anchor items are available, we proposed an extended model that simultaneously estimates item characteristic functions (ICFs) for anchor items, ICFs conditional on the covariate for non-anchor items, and the latent variable density conditional on the covariate-all using regression splines. A permutation DIF test is developed, and its performance is compared to the conventional parametric approach in a simulation study. We also illustrate the proposed semiparametric DIF testing procedure with an empirical example.

Initial Evaluation of the Pediatric PROMIS® Health Domains in Children and Adolescents With Sickle Cell Disease

BACKGROUND

The Patient Reported Outcomes Measurement Information System (PROMIS®) has developed pediatric self-report scales measuring several unidimensional health attributes (domains) suitable for use in clinical research, but these measures have not yet been validated in sickle cell disease (SCD).

PROCEDURE

A convenience sample of SCD children, aged 8-17 years, from two sickle cell programs was recruited at routine clinic visits, including some for hydroxyurea monitoring or monthly transfusions. Children completed PROMIS pediatric items using an online data collection platform, the PROMIS Assessment Center Web site.

RESULTS

A total of 235 participants (mean age 12.5 ± 2.8 years, 49.8% female) participated in the study. Adolescents (ages 12-17 years) reported significantly higher pain interference and depressive symptoms, and worse lower extremity physical functioning domain scores compared to younger children (ages 8-11 years). Female participants reported significantly higher pain interference, fatigue, and depressive symptoms, and worse lower extremity physical functioning domain scores compared with their male counterparts. Participants with hip or joint problems that limited usual activities reported significantly higher pain, fatigue, and depressive symptoms scores, and worse upper/lower extremity physical functioning scores as did participants who had experienced sickle pain in the previous 7 days.

CONCLUSIONS

PROMIS pediatric measures are feasible in a research setting and identify expected differences in known group comparisons in a sample of SCD children. The large domain score differences between those with or without SCD-related complications suggest the potential usefulness of these measures in clinical research, but further validation studies are needed, particularly in clinical practice settings.
