PROMIS® Parent Proxy Report Scales: an item response theory analysis of the parent proxy report item banks

Cross-sectional and longitudinal changes in body composition, anxiety, and depression in a clinical sample of adolescents with anorexia nervosa

OBJECTIVE

Eating disorders among children and adolescents have increased in prevalence, and mortality rates for anorexia nervosa are among the highest for any psychiatric disorder. Our current study aimed to (a) examine the cross-sectional relationship between body composition and anxiety/depressive symptoms among 97 adolescents and young adults who have been diagnosed with anorexia nervosa, (b) examine the longitudinal changes in body composition and anxiety/depressive symptoms over three months (from baseline to follow-up visit), and (c) examine the longitudinal relationship between change in body composition and change in anxiety/depression over three months.

METHOD

A retrospective chart review was conducted within an interdisciplinary eating disorder clinic between August 2019 and December 2021. In total, 97 adolescents aged 11-20 years old with diagnoses of anorexia nervosa were included in the analyses. Body composition data were collected at each visit along with parent- and youth-report measures of symptoms of anxiety/depression symptoms.

RESULTS

Findings indicated adolescents demonstrated some improvement in body composition, as well as parent-reported reductions in anxiety/depression symptoms. Based on parent reports, increased BMI percentile was associated with improvements in anxiety/depression symptoms. On the other hand, youth did not report significant changes in anxiety/depressive symptoms. Additionally, there were no associated improvements with body composition measures, which may be associated with continued body dissatisfaction or symptoms of anxiety and depression predating the eating disorder.

CONCLUSIONS

These results suggest the importance of including interventions addressing depression, anxiety, and body image as part of treatment.

Exploring Mental Health in a Pediatric Paradoxical Vocal Fold Motion Sample Using Patient-Reported Outcomes

OBJECTIVE

Paradoxical vocal fold motion (PVFM) is characterized by inappropriate adduction of vocal folds during inspiration causing dyspnea. While anxiety is suspected to be a predisposing factor, incidence has been understudied.

STUDY DESIGNS

Retrospective review.

SETTING

Multidisciplinary PVFM hospital clinic.

METHODS

We used patient-reported outcome measures to examine anxiety and depression in consecutive patients aged 10 to 17 years using Pediatric SFv1.1 Anxiety 8b and Level 2-Depression inventories (parents completed proxy forms). T-scores were classified as normal (none to slight <55) or elevated (mild 55-59.9, moderate 60-69.9, severe >70).

RESULTS

Twenty-three pediatric patients and 20 parents completed surveys. Mean age was 13.74 years. For anxiety, 69.6% of patients and 40% of parents identified elevated levels. For depression, 30.4% of patients and 15% of parents identified elevated levels. Therapy need for the sample was 65.2% (34.8% active in services and 30.4% referred). Child anxiety scores were significantly higher in the therapy need group, U = 17, P = .004.

CONCLUSION

This study of adolescents with PVFM confirmed elevated anxiety and depression scores in 2/3 of the participants. Anxiety likely precedes diagnosis and is a predisposing factor. Referral for individualized intervention targeting anxiety and depression is indicated.

Psychometric properties of the GAD-7 and PROMIS-Anxiety-4a among youth with depression and suicidality: Results from the Texas youth depression and suicide research network

There is a tremendous need for brief, valid, and free assessments of anxiety in child mental healthcare. The goal of this study was to determine the psychometric properties of two such measures, the GAD-7 and PROMIS-Anxiety-4a, in 1000 children, adolescents, and young adults (8-20 years-old) with depression and/or suicidality. The GAD-7, the PROMIS-Anxiety-4a, and other validated assessments of anxiety, physical functioning, and psychiatric diagnoses were completed. Confirmatory factor analyses showed an acceptable fit for a single factor in both measures via all indices but the RMSEA. They demonstrated measurement invariance across pre-adolescents (8-12 years-old) and adolescents and emerging adults (13-20 years-old), though scalar invariance was not observed for the GAD-7. Both measures showed strong convergent validity, GAD-7: r = 0.68; PROMIS-Anxiety-4a: r = 0.75, divergent validity with a measure of physical function, GAD-7: r = -0.24; PROMIS-Anxiety-4a: r = -0.28, good internal consistency, ω = 0.89 for both, and high test-retest reliability, GAD-7: r = 0.69; PROMIS-Anxiety-4a: r = 0.71. Both measures also showed acceptable sensitivity and specificity in detecting the presence of any anxiety disorder, GAD-7 cut-off score of 10: AUC = 0.75; PROMIS-Anxiety-4a cutoff score of 12: AUC = 0.79. The GAD-7 correlated similarly with the Screen for Child Anxiety Related Disorders total score and generalized anxiety subscale, and also showed similar diagnostic sensitivity and specificity when used to detect the presence of any anxiety disorder vs. generalized anxiety disorder specifically. Results suggest that both of these brief, publicly available instruments are valid and reliable assessments of anxiety among youth in treatment for depression and/or suicidality.

Administering selected subscales of patient-reported outcome questionnaires to reduce patient burden and increase relevance: a position statement on a modular approach

Patient-reported outcome (PRO) questionnaires considered in this paper contain multiple subscales, although not all subscales are equally relevant for administration in all target patient populations. A group of measurement experts, developers, license holders, and other scientific-, regulatory-, payer-, and patient-focused stakeholders participated in a panel to discuss the benefits and challenges of a modular approach, defined here as administering a subset of subscales out of a multi-scaled PRO measure. This paper supports the position that it is acceptable, and sometimes preferable, to take a modular approach when administering PRO questionnaires, provided that certain conditions have been met and a rigorous selection process performed. Based on the experiences and perspectives of all stakeholders, using a modular approach can reduce patient burden and increase the relevancy of the items administered, and thereby improve measurement precision and eliminate wasted data without sacrificing the scientific validity and utility of the instrument. The panelists agreed that implementing a modular approach is not expected to have a meaningful impact on item responses, subscale scores, variability, reliability, validity, and effect size estimates; however, collecting additional evidence for the impact of context may be desirable. It is also important to recognize that adequate rationale and evidence (e.g., of fit-for-purpose status and relevance to patients) and a robust consensus process that includes patient perspectives are required to inform selection of subscales, as in any other measurement circumstance, is expected. We believe that the considerations discussed within (content validity, administration context, and psychometric factors) are relevant across multiple therapeutic areas.

Codesign of remote data collection for chronic management of pediatric home mechanical ventilation

INTRODUCTION

Outpatient monitoring of children using invasive home mechanical ventilation (IHMV) is recommended, but access to care can be difficult. This study tested if remote (home-based) data collection was feasible and acceptable in chronic IHMV management.

METHODS

A codesign study was conducted with an IHMV program, home nurses, and English- and Spanish-speaking parent-guardians of children using IHMV (0-17 years; n = 19). After prototyping, parents used a remote patient monitoring (RPM) bundle to collect patient heart rate, respiratory rate (RR), oxygen saturation, end-tidal carbon dioxide (EtCO2 ), and ventilator pressure/volume over 8 weeks. User feedback was analyzed using qualitative methods and the System Usability Scale (SUS). Expected marginal mean differences within patient measures when awake, asleep, or after a break were calculated using mixed effects models.

RESULTS

Patients were a median 2.9 years old and 11 (58%) took breaks off the ventilator. RPM data were entered on a mean of 83.7% (SD ± 29.1%) weeks. SUS scores were 84.8 (SD ± 10.5) for nurses and 91.8 (SD ± 10.1) for parents. Over 90% of parents agreed/strongly agreed that RPM data collection was feasible and relevant to their child's care. Within-patient comparisons revealed that EtCO2 (break-vs-asleep 2.55 mmHg, d = 0.79 [0.42-1.15], p < .001; awake-vs-break 1.48, d = -0.49 [0.13-0.84], p = .02) and RR (break-vs-asleep 16.14, d = 2.12 [1.71-2.53], p < .001; awake-vs-break 3.44, d = 0.45 [0.10-0.04], p = .03) were significantly higher during ventilator breaks.

CONCLUSIONS

RPM data collection in children with IHMV was feasible, acceptable, and captured clinically meaningful vital sign changes during ventilator breaks, supporting the clinical utility of RPM in IHMV management.

The Burden of Sickle Cell Disease on Children and Their Caregivers: Caregiver Reports of Children's Health-Related Quality of Life and School Experiences, Caregiver Burden, and Their Association with Frequency of Vaso-Occlusive Crises

Background

Children with sickle cell disease (SCD) experience a multiplex of disease-related symptoms and complications, including vaso-occlusive crises (VOCs), episodes characterized by extreme pain.

Methods

A cross-sectional observational survey examined the health-related quality of life (HRQoL) and school experiences of children with SCD 2 months-11 years, burden experienced by their caregivers, and associations between these outcomes and VOC frequency. Caregivers (N=167) of children with SCD in the US completed the Infant-Toddler Quality of Life-Short Form 47 (ITQoL-SF47) for children 2 months-4 years, the Child Health Questionnaire-Parent Form 50 (CHQ-PF50) and PROMIS Pain Interference and Sleep Disturbance Parent Proxy short forms for children 5-11 years, and a study-specific survey of school experiences.

Results

Children with SCD 2 months-4 years had lower ITQoL-SF47 scores (ie, worse HRQoL, p<0.001) than a normative sample of children; across domains, differences ranged from 18.73-45.03 points and exceeded minimal important difference (MID) thresholds. Except for the behavior domain, children with SCD 5-11 years had lower scores on all CHQ-PF50 domains than the normative sample (p<0.001); differences ranged from 6.78-36.37 points and exceeded MID thresholds. Children with more frequent VOCs had lower HRQoL and worse school experiences than children with less frequent VOCs (p<0.05, except for behavior domains). The largest differences based on VOC frequency were observed for overall health and bodily pain/discomfort among children 2 months-4 years (differences=40.88 and 32.50 points, respectively), and bodily pain and role/social limitations due to physical health among children 5-11 years (differences=38.99 and 37.80, respectively). Caregivers of children with more frequent VOCs experienced greater burden than caregivers of children with less frequent VOCs, though specific areas of impact (eg, caregiver emotions, time) differed across child age groups.

Conclusion

VOC frequency is negatively associated with HRQoL, highlighting the burden experienced by children with SCD and their caregivers.

Development of the Nighttime Parenting Scale: Differentiating nighttime versus general parenting practices and their impact on youth sleep health

OBJECTIVES

The current study provides a novel method of assessing the impact of nighttime parenting practices on youth sleep health during the sensitive transition from childhood to adolescence (ie., peri-puberty). Specifically, we aimed to advance the measurement of nighttime parenting by developing a conceptually driven questionnaire for use in research and clinical settings.

METHOD

A total of 625 parents (67.9% mothers) of peripubertal youth (age M=11.6, SD=1.31) were recruited online and completed self-report questionnaires. The sample was primarily White (67.4%), followed by 16.5% Black, 13.1% Latinx, and 9.6% Asian. Factor structure was examined through four empirically-driven stages (ie, exploratory factor analyses, confirmatory factor analyses, examining internal and test-retest reliability, and indices of validity). Furthermore, the current study sought to validate nighttime parenting as a unique construct by exploring associations with peripubertal youth sleep health.

RESULTS

A factor structure consisting of six dimensions of nighttime parenting was established (ie, nighttime supportiveness, hostility, physical control, limit-setting, media monitoring, and co-sleeping behaviors). Furthermore, the current measure demonstrated strong psychometric properties. Finally, the established dimensions were cross-sectionally associated with youth sleep health indices.

CONCLUSIONS

This study extends previous research by examining the influence of distinct domains of parenting practices that specifically occur at nighttime and how these differentially relate to youth sleep health. Results suggest that intervention and/or prevention programs targeting sleep should place emphasis on fostering positive parenting at nighttime as a strategy for creating an evening environment that is conducive to optimizing youth sleep health.

Patient-Reported Outcomes Over 24 Months in Pediatric CKD: Findings From the MyKidneyHealth Cohort Study

RATIONALE & OBJECTIVE

The lived experience of children with chronic kidney disease (CKD) is poorly characterized. We examined the associations between patient-reported outcome (PRO) scores measuring their fatigue, sleep health, psychological distress, family relationships, and global health with clinical outcomes over time in children, adolescents, and younger adults with CKD and investigated how the PRO scores of this group compare with those of other children, adolescents, and younger adults.

STUDY DESIGN

Prospective cohort study.

SETTING & PARTICIPANTS

212 children, adolescentss, and adults aged 8 to 21 years with CKD and their parents recruited from 16 nephrology programs across North America.

PREDICTORS

CKD stage, disease etiology, and sociodemographic and clinical variables.

OUTCOME

PRO scores over 2 years.

ANALYTICAL APPROACH

We compared PRO scores in the CKD sample with a nationally representative general pediatric population (ages 8 to 17 years). Change of PROs over time and association of sociodemographic and clinical variables with PROs were assessed using multivariable regression models.

RESULTS

For all time points, 84% of the parents and 77% of the children, adolescents, and younger adults completed PRO surveys . The baseline PRO scores for the participants with CKD revealed a higher burden of fatigue, sleep-related impairment, psychological distress, impaired global health, and poorer family relationships compared with the general pediatric population, with median score differences≥1 SD for fatigue and global health. The baseline PRO scores did not differ by CKD stage or glomerular versus nonglomerular etiology. Over 2 years, PROs were stable with a<1-point annual change on average on each measure and intraclass correlation coefficients ranging from 0.53 to 0.79, indicating high stability. Hospitalization and parent-reported sleep problems were associated with worse fatigue, psychological health, and global health scores (all P<0.04).

LIMITATIONS

We were unable to assess responsiveness to change with dialysis or transplant.

CONCLUSIONS

Children with CKD experience a high yet stable burden of impairment across numerous PRO measures, especially fatigue and global health, independent of disease severity. These findings underscore the importance of assessing PROs, including fatigue and sleep measures, in this vulnerable population.

PLAIN-LANGUAGE SUMMARY

Children with chronic kidney disease (CKD) have many treatment demands and experience many systemic effects. How CKD impacts the daily life of a child is poorly understood. We surveyed 212 children, adolescents, and younger adults with CKD and their parents over 24 months to assess the participants' well-being over time. Among children, adolescents, and younger adults with CKD we found a very high and persistent burden of psychological distress that did not differ by degree of CKD or type of kidney disease. The participants with CKD endorsed greater impairment in fatigue and global health compared with healthy children, adolescents, and younger adults, and parent-reported sleep problems were associated with poorer patient-reported outcome (PRO) scores across all domains. These findings emphasize the importance of including PRO measures, including fatigue and sleep measures, into routine clinical care to optimize the lived experience of children with CKD.

Mindfulness and cognitive emotion regulation in pediatric misophonia

Misophonia is characterized by decreased tolerance of ordinary human-generated trigger sounds and associated visual stimuli (e.g., chewing, sniffing, lip smacking), coupled with intense affective reactions. The disorder often begins during childhood or adolescence and is associated with impairment and distress in numerous life domains. Research has begun to examine the underlying psychological mechanisms of misophonia in adults, but studies in youth are limited. Trait mindfulness (i.e., nonjudgmental and nonavoidant present-moment awareness) and cognitive emotion regulation (i.e., cognitive processing, or responding to, emotionally arousing situations) are two proposed mechanisms that may underpin pediatric misophonia and associated functional impairment. In the present exploratory cross-sectional study, we examined trait mindfulness and cognitive emotion regulation and their relations with misophonia features and adaptive functioning in 102 youth with misophonia (Mage = 13.7; SD = 2.5; range = 8-17). More severe misophonia was significantly associated with decreased levels of both trait mindfulness and adaptive functioning across domains, in addition to deficits in certain facets of cognitive emotion regulation, particularly self-blame. Neither trait mindfulness nor facets of cognitive emotion regulation moderated the association between misophonia severity and adaptive functioning across domains, with the notable exception that difficulties with adaptive functioning in peer relationships was attenuated in those high in mindfulness. Findings suggest that trait mindfulness- and to a lesser extent cognitive emotion regulation- may be potentially relevant processes in pediatric misophonia. However, more research is needed to uncover the precise nature of these processes to aid future characterization and intervention efforts, especially in light of equivocal findings in the present study.

A case study of virtually delivered emotion-focused family therapy

Clinical psychologists and therapists are increasingly taking advantage of internet and mobile-based technologies to deliver mental health services for individuals and groups since the COVID-19 pandemic. However, there is a dearth of research evaluating the appropriateness of virtual platforms for family interventions. Further, no research has examined the effectiveness of weekly emotion-focused family therapy (EFFT). This case study presents a virtually delivered 8-week EFFT intervention, which supported caregivers to manage child symptoms of depression, anxiety, and anger, facilitate emotion processing, and strengthen relationships. Two parents from one family during a marital separation participated and completed brief measures of therapeutic alliance, family functioning, parental self-efficacy, and parental and child psychological distress at 12 time points as well as a posttreatment semistructured interview. A strong therapeutic alliance was formed, and general family functioning, parental self-efficacy, parent psychopathology, and child depression, anger, and anxiety symptoms improved over the course of therapy.

The Patient-Reported Outcomes Measurement Information System (PROMIS) pediatric and parent-proxy short forms for anxiety: Psychometric properties in the Kids FACE FEARS sample

There is tremendous need for brief and supported, non-commercial youth- and caregiver-report questionnaires of youth anxiety. The pediatric and parent proxy short forms of the Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety scale (8a v2.0) are free, brief, publicly accessible measures of youth- and caregiver-reported anxiety in children and adolescents. Despite increased use of the PROMIS, no study has evaluated performance of its anxiety scales in a sample of treatment-engaged anxious youth. Analyses were conducted on baseline data from the first 265 families (child M_Age=11.14 years, 70% racial/ethnic minoritized youth) to enroll in the Kids FACE FEARS trial, a multisite comparative effectiveness trial of therapist-led vs. self-administered treatment for elevated youth anxiety. Confirmatory factor analysis (CFA) examined factor structure; omega coefficients and regression models examined internal consistency, convergent validity, and cross-informant reliability. CFA supported adjusted single-factor solutions across youth and caregiver reports, and internal consistency was high. Convergent validity was supported by medium-to-large associations with anxiety-related impairment and severity. Moderate cross-informant reliability between reports was found. Results showcase the first psychometric study of the PROMIS Anxiety scale short forms among treatment-engaged youth with elevated anxiety. Findings highlight the PROMIS Anxiety scale's utility in typical care settings for youth anxiety.

German translation of the PROMIS® pediatric anxiety, anger, depressive symptoms, fatigue, pain interference and peer relationships item banks

BACKGROUND

The present study aimed at the translation and cross-cultural adaptation of six PROMIS^® pediatric self- and proxy- item banks and short forms to universal German: anxiety (ANX), anger (ANG), depressive symptoms (DEP), Fatigue (FAT), pain interference (P) and peer relationships (PR).

METHODS

Using standardized methodology approved by the PROMIS Statistical Center and in line with recommendations of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) PRO Translation Task Force, two translators for each German-speaking country (Germany, Austria, and Switzerland) commented on and rated the translation difficulty and provided forward translations, followed by a review and reconciliation phase. An independent translator performed back translations, which were reviewed and harmonized. The items were tested in cognitive interviews with 58 children and adolescents from Germany (16), Austria (22), and Switzerland (20) for the self-report and 42 parents and other caregivers (Germany (12), Austria (17), and Switzerland (13)) for the proxy-report.

RESULTS

Translators rated the translation difficulty of most items (95%) as easy or feasible. Pretesting showed that items of the universal German version were understood as they were intended, as only 14 out of 82 items of the self-report and 15 out of 82 items of the proxy-report versions required minor rewording. However, on average German translators rated the items more difficult to translate (M = 1.5, SD = 0.20) than the Austrian (M = 1.3, SD = 0.16) and the Swiss translators (M = 1.2, SD = 0.14) on a three-point Likert scale.

CONCLUSIONS

The translated German short forms are ready for use by researchers and clinicians ( https://www.healthmeasures.net/search-view-measures ).

Parental self-efficacy managing a child's medications and treatments: adaptation of a PROMIS measure

PURPOSE

Self-efficacy is important for managing chronic conditions; however, its measurement in pediatric healthcare settings remains rare. The goal of this project was to adapt an existing disease-agnostic adult self-efficacy patient reported outcome (PRO) measure to enhance suitability of items for measuring the self-efficacy of parents that manage their children's health conditions.

METHODS

We adapted the existing Patient-Reported Outcomes Measurement Information System® (PROMIS®) adult self-efficacy healthcare measure to parental voice. First, a targeted literature review informed rephrasing of the adult items and identification of new pediatric-specific content. The initial item pool was revised based on input from 12 multidisciplinary experts. Next cognitive interviews of adapted items were simultaneously conducted with English and Spanish-speaking parents of pediatric patients with a range of chronic and/or disabling conditions recruited from a Midwestern children's hospital to finalize the measure.

RESULTS

Findings resulted in an initial item pool of 33 pediatric-specific items which were narrowed to 31 draft items based on expert input. Parent cognitive interview findings (N = 26) informed further item reduction resulting in a final measure consisting of 30 items representing nine domains. Fourteen items are relevant to children regardless of condition severity (e.g., health care information/decision making; symptom identification/management) and 16 items are relevant to children with specific health care needs (e.g., medication usage, equipment).

CONCLUSION

We conducted a first step in developing a condition-agnostic, PRO measure of parental self-efficacy managing their children's chronic and/or disabling conditions that is acceptable and understandable to English and Spanish-speaking parents.

Pediatric Patient and Caregiver Agreement on Perioperative Expectations and Self-Reported Outcomes

INTRODUCTION

Alignment between pediatric patients and caregiver perspectives on patient-reported outcome (PRO) data is contingent upon context. We aimed to assess agreement between patient and caregiver responses to a series of perioperative domains.

METHODS

Agreement between pediatric patients and caregiver responses to preoperative and postoperative surveys about surgery preparedness, perioperative expectations, PRO Measurement Information System (PROMIS) measures for overall health and pain, and reaching milestones gathered as part of an ongoing clinical trial for children undergoing gastrointestinal surgery, was evaluated. Gwet's AC and Spearman's correlation coefficients were calculated, as appropriate, to assess agreement.

RESULTS

Of 209 enrolled patients, 65 (31.1%) dyads completed all three surveys and were included. For the domains of education, expectations, and comprehension, patients and caregivers had good agreement with Gwet AC1 with values of 0.80, 0.61, and 0.64, respectively. For milestones, patients and caregivers had very good agreement (Gwet AC1 of 0.95). Milestones measured whether patients achieved certain goals within a prespecified time, including enteral intake (Gwet AC1 0.91 and 0.92 respectively), transition to oral pain medication (Gwet AC1 0.94), ambulation (Gwet AC1 1.00), and return of bowel function (Gwet AC1 0.97). There was moderate to strong agreement between patients and caregivers on PROMIS pain questions (Spearman's correlation: 0.71 preoperatively and 0.51 postoperatively). On PROMIS global health questions, there was strong agreement (0.69 preoperatively and 0.65 postoperatively).

CONCLUSIONS

Pediatric patient and caregiver agreement on perioperative survey items ranged from moderate to strong. Caregivers' responses may be acceptable when some patient-level responses are not available.

Predictors of missed school days among military connected families: A feasibility study

BACKGROUND

There is a paucity of research specific to military children's health, especially those with special needs. This may be partly attributed to the difficulty in accessing military connected families as a population. Yet, given the recognized importance of military connected families to the national security agenda, a need exists for studies to explore factors underlying child and family health.

PURPOSE

We sought to identify factors among a sample of military children with special health care needs (CSHCN) predictive of missed school days, a commonly used measure of health and one used by NPs to monitor chronic conditions management success.

METHODOLOGY

We used a secondary data analysis design and multivariable logistic regression with a subsample of military connected families from the National Survey of CSHCN identified by their reported insurance type.

RESULTS

We identified 1,656 military CSHCN. According to the adjusted model, hours of care per week, family work hours change, and activity limitations for the child were positive predictors of ≥4 missed school days per year.

CONCLUSION/IMPLICATIONS

Our models identified important predictors of missed school days among military children that may inform assessments, interventions, and referrals by nurse practitioners caring for them. We identified a robust sample of military CSHCN from the National Survey of CSHCN by using self-reported insurance, a novel and simple approach to conducting a focused study of this population. Although feasible, this sampling approach was not without limitations. We advocate for including military connected families within sampling frameworks of national surveys to ensure that studies with this critical and unique population continue.

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.

Pacific Islands Cohort on Cardiometabolic Health Study: rationale and design

BACKGROUND

Pacific Islanders, including those residing in the US Affiliated Pacific Islands (USAPI), experience some of the highest mortality rates resulting from non-communicable diseases (NCDs) worldwide. The Pacific Island Health Officers' Association declared a Regional State of Health Emergency in 2010 due to the epidemic of NCDs in the USAPI. Obesity, a known risk factor for NCDs, has become an epidemic among both children and adults in Micronesia and other parts of the USAPI. There is some recent information about overweight and obesity (OWOB) among young children in the USAPI, but there is no data looking at the relationship between children and their biological parents. The Pacific Islands Cohort on Cardiometabolic Health (PICCAH) Study aims to collect data on NCD lifestyle factors from two generations of families (n = 600 child-parent dyads or 1,200 participants) living in Guam, Pohnpei, and Palau.

METHODS

The PICCAH Study is an epidemiological study using community-based convenience sampling to recruit participants in USAPI of Guam, Palau, and Pohnpei. The goal is to recruit participant dyads consisting of 1 child plus their biological parent in Guam (500 dyads or 1,000 participants), Pohnpei (50 dyads or 100 participants), and Palau (50 dyads or 100 participants). All participants are having the following information collected: demographic, health, and lifestyle information; anthropometry; diet; physical activity; sleep; acanthosis nigricans; blood pressure; and serum levels of fasting plasma glucose, fasting insulin, glycated hemoglobin, total cholesterol, triglycerides, LDL, and HDL.

DISCUSSION

The PICCAH Study is designed to establish the baseline of a generational epidemiologic cohort with an emphasis on cardiometabolic risk, and to better understand the extent of DM and CVD conditions and related risk factors of those living in the USAPI jurisdictions of Guam, Pohnpei, and Palau. This study also serves to further build research capacity in the underserved USAPI Region.

Irritability and Emotional Impulsivity as Core Feature of ADHD and ODD in Children

The categorical approach of diagnosing mental disorders entails the problem of frequently occurring comorbidities, suggesting a more parsimonious structure of psychopathology. In this study, we therefore aim to assess how affective dysregulation (AD) is associated with attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) in children. To assess AD in children aged 8–12 years (n = 391), we employed the parent version of a newly constructed parent rating scale. Following item reduction, we conducted exploratory and confirmatory factor analyses to establish a factorial structure of AD. One core dimension was identified, comprising irritability and emotional impulsivity, and two smaller dimensions, comprising positive emotionality and exuberance. Subsequently, we examined five different latent factor models – a unidimensional model, a first-order correlated factor model, a second-order correlated factor model, a traditional bifactor model, and a bifactor S-1 model, in which the first-order factor AD-Irritability/Emotional Impulsivity (II) was modeled as the general reference factor. A bifactor S-1 model with the a priori defined general reference domain AD-II provided the best fit to our data and was straightforward to interpret. This model showed excellent model fit and no anomalous factor loadings. This still held true, when comparing it to bifactor S-1 models with ADHD/ODD-related reference factors. Differential correlations with emotion regulation skills and the established Parent Proxy Anger Scale validate the interpretation of the different dimensions. Our results suggest that irritability/emotional impulsivity might be a common core feature of ADHD and ODD.

Systematic Review of Conceptual, Age, Measurement and Valuation Considerations for Generic Multidimensional Childhood Patient-Reported Outcome Measures

BACKGROUND AND AIMS

Patient-reported outcome measures (PROMs) for children (aged ≤ 18 years) present methodological challenges. PROMs can be categorised by their diverse underlying conceptual bases, including functional, disability and health (FDH) status; quality of life (QoL); and health-related quality of life (HRQoL). Some PROMs are designed to be accompanied by preference weights. PROMs should account for childhood developmental differences by incorporating age-appropriate health/QoL domains, guidance on respondent type(s) and design. This systematic review aims to identify generic multidimensional childhood PROMs and synthesise their characteristics by conceptual basis, target age, measurement considerations, and the preference-based value sets that accompany them.

METHODS

The study protocol was registered in the Prospective Register of Systematic Reviews (CRD42021230833), and reporting followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We conducted systematic database searches for generic multidimensional childhood PROMs covering the period 2012-2020, which we combined with published PROMs identified by an earlier systematic review that covered the period 1992-2011. A second systematic database search identified preference-based value sets for generic multidimensional PROMs. The PROMs were categorised by conceptual basis (FDH status, QoL and HRQoL) and by target age (namely infants and pre-schoolers aged < 5 years, pre-adolescents aged 5-11, adolescents aged 12-18 and multi-age group coverage). Descriptive statistics assessed how PROM characteristics (domain coverage, respondent type and design) varied by conceptual basis and age categories. Involvement of children in PROM development and testing was assessed to understand content validity. Characteristics of value sets available for the childhood generic multidimensional PROMs were identified and compared.

RESULTS

We identified 89 PROMs, including 110 versions: 52 FDH, 29 QoL, 12 HRQoL, nine QoL-FDH and eight HRQoL-FDH measures; 20 targeted infants and pre-schoolers, 29 pre-adolescents, 24 adolescents and 37 for multiple age groups. Domain coverage demonstrated development trajectories from observable FDH aspects in infancy through to personal independence and relationships during adolescence. PROMs targeting younger children relied more on informant report, were shorter and had fewer ordinal scale points. One-third of PROMs were developed following qualitative research or surveys with children or parents for concept elicitation. There were 21 preference-based value sets developed by 19 studies of ten generic multidimensional childhood PROMs: seven were based on adolescents' stated preferences, seven were from adults from the perspective of or on behalf of the child, and seven were from adults adopting an adult's perspective. Diverse preference elicitation methods were used to elicit values. Practices with respect to anchoring values on the utility scale also varied considerably. The range and distribution of values reflect these differences, resulting in value sets with notably different properties.

CONCLUSION

Identification and categorisation of generic multidimensional childhood PROMs and value sets by this review can aid the development, selection and interpretation of appropriate measures for clinical and population research and cost-effectiveness-based decision-making.

Brief, parent-led, transdiagnostic cognitive-behavioral teletherapy for youth with emotional problems related to the COVID-19 pandemic

BACKGROUND

The COVID-19 pandemic has led to increased stress, anxiety, and depression in children. A six-session, parent-led, transdiagnostic, cognitive-behavioral teletherapy program was adapted from an established protocol to help youth aged between 5 and 13 years manage emotional problems during the pandemic.

METHODS

One-hundred twenty-nine parents of youth struggling with emotional problems during the COVID-19 pandemic participated in the program. Parents reported on their children's psychosocial functioning before and after treatment using validated assessments. They also reported on treatment satisfaction. Clinician-rated global improvement was assessed at each session to determine clinically significant treatment response.

RESULTS

Significant improvements in parent proxy-reported anxiety (d = 0.56), depression (d = 0.69), stress (d = 0.61), anger (d = 0.69), family relationships (d = 0.32), and COVID-19-related distress (d = 1.08) were found, with 62% of participants who completed the program being classified as treatment responders. Parents reported high levels of satisfaction with the program.

LIMITATIONS

This study was limited by use of primarily parent-report assessments and a lack of a control group.

CONCLUSIONS

Brief, parent-led, transdiagnostic cognitive-behavioral teletherapy appeared to be an effective way to help youth cope with the pandemic and may be a scalable framework in response to large-scale mental health crises.

Interplay of disability, caregiver impact, and out-of-pocket expenditures in Duchenne muscular dystrophy: a cohort study

Background

Providing caregiving support to people with Duchenne muscular dystrophy (DMD) is challenging, beginning in early childhood, and continuing through the progression of multidimensional disability. This study addressed the interplay between caregiver impact, out-of-pocket expenditures, and DMD disability. To examine these interconnections, we investigated the association between caregiver impact domains and out-of-pocket expenditures; and the presence of clusters in caregivers on the basis of DMD-related disability domains in the patients for whom they provided caregiving support.

Methods

This web-based study recruited 566 DMD caregivers (140 males, 426 females; mean age 41.6 years, SD 8.8, range 21–72), examining caregiver impact using the DMD Caregiver Impact Measure, PROMIS-derived parent-proxy (PPP) measures of their child’s disability, and items tapping out-of-pocket expenditures related to home and vehicle accommodations and assistive devices. T-tests compared caregiver impact scores by out-of-pocket expenditures incurred. Latent Profile Analyses (LPA) were conducted to generate impact profiles related to child’s disability as reported by caregiver proxies.

Results

Higher out-of-pocket expenditures were generally associated with worse impact on the subscales, but several expenditures (e.g., kitchen, bathroom, scooter) were associated with lower impact. LPA indicated that the four-group solution provided the best relative fit and yielded good profile separation (entropy = 0.91). Caregivers with lowest impact reported the highest mobility, cognitive, and upper extremity functioning of their DMD care recipients, whereas the highest caregiver impact was driven by their care recipient’s negative affect and fatigue. The upper-middle impact group showed great variability in proxy-disability domains, whereas the lower-middle group had similar levels of disability across domains. Profiles were represented across all child ages.

Conclusion

Out-of-pocket expenditures were often associated with worse caregiver impact, but some associated with milder impact (i.e., bathroom or kitchen modification, investing in a ceiling lift or medical scooter). While their son’s level of disability and age were related to impact on the DMD caregiver, the domains giving rise to highest caregiver impact were not the most visible aspects of disability, such as mobility, but rather negative affect and fatigue. Other contextual attributes are likely implicated, and will be addressed in the companion paper.

Development and validation of the Modeling of Parental Anxiety Questionnaire

Parental anxious modeling is assumed to be a risk factor for child anxiety. Until now there has been no self-assessment scale available that measures parental modeling of anxiety in a comprehensive way. Our aim with this study was to bridge this gap by developing the Modeling of Parental Anxiety Questionnaire (MPAQ). To do this, we generated an item pool containing 51 statements covering different aspects of parental modeling of anxious and non-anxious behaviors. A sample of Swedish parents (N = 1092) of children aged 4-12, answered an online survey comprising the generated item pool, the Parental Overprotection Scale (OP) and the PROMIS Anxiety short forms (the adult version and the parent proxy report scale). A factor analysis of the items of parental modeling indicated a structure with four separate factors. These factors formed the final four subscales of MPAQ; (1) being curios and content, (2) being on guard, (3) displaying anxiety and avoidance, and (4) displaying stress. The Cronbach's alpha coefficients of the subscale scores ranged from moderate to good. Linear regression analysis showed that the displaying anxiety and avoidance-subscale had the strongest association with child anxiety symptoms. These findings show that MPAQ demonstrates adequate psychometric properties and has potential for being used in research and clinical settings, for example to identify potential targets for parenting interventions and to measure mediation effects.

Measuring Duchenne muscular dystrophy impact: development of a proxy-reported measure derived from PROMIS item banks

BACKGROUND

Person-reported outcomes measurement development for rare diseases has lagged behind that of more common diseases. In studies of caregivers of patients with rare diseases, one relies on proxy report to characterize this disability. It is important to measure the child's disability accurately and comprehensively because it affects caregiver burden. We aimed to create a condition-specific caregiver proxy-report measure for Duchenne Muscular Dystrophy (DMD) in order to understand the impact of DMD on the caregiver. Drawing on relevant item banks from the Patient-Reported Outcome Measurement Information System (PROMIS), we sought to confirm their reliability and validity in the target sample of DMD caregivers.

METHODS

This web-based study recruited DMD caregivers via Rare Patient Voice, patient-advocacy groups, and word of mouth. Recruitment was stratified by age of the caregiver's child with DMD, which broadly represents stages of DMD progression: 2-7, 8-12, 13-17, and > 18. Telephone interviews with DMD parent-caregivers pretested possible measures for content validity. The web-based study utilized an algorithm to categorize respondents' ambulatory status for tailored administration of PROMIS Parent-Proxy items as well as some new items developed based on caregiver interviews. Item response theory analyses were implemented.

RESULTS

The study sample included 521 DMD caregivers representing equally the four age strata. The proxy-report measure included the following domains: fatigue impact, strength impact, cognitive function, upper extremity function, positive affect, negative affect, sleep-device symptoms, and mobility. The first five domains had strong psychometric characteristics (unidimensionality; acceptable model fit; strong standardized factor loadings; high marginal reliability). Negative Affect, covering anger, anxiety, depressive symptoms, and psychological stress, fit a bifactor model with good model fit, high marginal reliability, and strong factor loadings. The Sleep-device symptoms domain was not unidimensional, and the mobility domain did not have a simple structure due to residual correlations among items at opposite end of the mobility-disability continuum. These two domain scores were retained as clinimetric indices (i.e., uncalibrated scales), to achieve the overall goal of having a content-valid DMD-specific measure across all stages of disease severity.

CONCLUSIONS

The present study derived a DMD-specific proxy-report measure from PROMIS item banks and supplemental items that could potentially be utilized in caregiver research across all stages of the care recipient's DMD. Future research will focus on assessing the responsiveness and validity of the measure over time and its comparison to DMD patient self-report.

Preliminary Validation of the Pain Burden Inventory in a Pediatric Chronic Pain Population

OBJECTIVE

To determine the preliminary reliability and validity of the Pain Burden Inventory-Youth (PBI-Y), a 7-item measure of the impact of chronic pain in adolescents with chronic pain that was, initially validated in youth with sickle cell disease.

MATERIALS AND METHODS

A retrospective chart review of 130 patients presenting to an interdisciplinary pain clinic were examined with 98 (mean age=14.49; 66% female) comprising the final sample. Demographic information as well as adolescent and parent self-reported measures were examined.

RESULTS

Youth reported a variety of pains including abdominal pain, headaches, back pain, and amplified musculoskeletal pain. The PBI-Y demonstrated strong internal reliability (α=0.792) and strong cross-informant concordance (r=0.822; P=0.000). Good construct validity was seen where higher scores on the PBI-Y were correlated with higher scores of (1) functional disability (r=0.689; P=0.000), (2) pain catastrophizing (r=0.494; P=0.000), (3) pain frequency days (r=0.526; P=0.000), (4) usual pain intensity (r=0.467; P=0.000), and (5) the worst pain intensity (r=0.485; P=0.000). Similar results were seen with caregiver assessments. Neither caregiver nor youth reports differed based on the sex or age of the child.

DISCUSSION

The results support the psychometric properties of a brief self-report measure of pain impact in a pediatric chronic pain population. This measure may have great utility for clinicians caring for youth with chronic pain.

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.

Assessing anger and irritability in children: psychometric evaluation and normative data for the German version of the PROMIS® Parent Proxy Anger Scale

Purpose

Anger and irritability are common and impairing symptoms in children. The PROMIS Anger scales assess self- and parent-reported irritable and angry mood over the past 7 days. The aim of this study was to evaluate the psychometric properties of the German version of the PROMIS Parent Proxy Short Form v1.0—Anger and to provide normative data.

Methods

To evaluate the psychometric properties, data from the study ADOPT Epidemiology were used. In this study, the PROMIS Anger Scale was administered to a population-based sample of n = 8746 parents of children aged 8–12 years. Psychometric analyses were carried out including the investigation of distribution characteristics, factor structure, model fit, internal consistency, and congruent validity. Normative data were calculated as percentile ranks and T-scores.

Results

The PROMIS Anger Scale demonstrated good psychometric properties, including satisfactory distribution characteristics, unidimensionality, good internal consistency as well as congruent validity. German normative data for the PROMIS Anger Scale are presented.

Conclusion

Based on first psychometric analyses, the German version of the PROMIS Anger Scale can be recommended for use in research and practice; however, further investigations using clinical data are needed. The normative data will allow researchers and clinicians an interpretation of the test scores in future applications.

Coping, Anxiety, and Health Care Transition Readiness in Youth with Chronic Conditions

PURPOSE

To explore the relationship between coping and health care transition readiness, and to examine whether anxiety is a mediator between coping and health care transition readiness.

DESIGN AND METHODS

A sample of 174 youths with various chronic conditions (age 13.03 ± 2.02 years, 48.3% male) attending the 2018 Victory Junction Camp and their parents participated. Youths and parents completed measures to assess coping (Kidcope Checklist), anxiety symptoms (PROMIS Anxiety scale), and transition readiness (STARx Questionnaire) through Qualtrics online surveys.

RESULTS

Positive coping was positively related to transition readiness in both youth and parent-proxy reports, while negative coping was negatively related to transition readiness in youth reports. Anxiety mediated the relationship of positive coping and transition readiness in parent-proxy reports, and the relationship of negative coping and transition readiness in both youth self-reports and parent-reports.

CONCLUSIONS

Coping is an important factor in transition readiness. Furthermore, anxiety is an important mediator, and may be more influential in the relationship of negative coping and transition readiness.

PRACTICE IMPLICATIONS

Practitioners and health care providers can use these findings to promote the use of positive coping and reduce the use of negative coping, which in turn may improve outcomes for youth with chronic health conditions who are transitioning to adult health care services.

Children's Beliefs about Pain: An Exploratory Analysis

Functional abdominal pain (FAP) is one of the most common childhood medical complaints, associated with significant distress and impairment. Little is known about how children understand their pain. Do they attribute it to personal weakness? Do they perceive pain as having global impact, affecting a variety of activities? How do they cope with pain? We explored the pain beliefs of 5- to 9-year-old children with FAP using a novel Teddy Bear Interview task in which children answered questions about a Teddy bear's pain. Responses were analyzed quantitatively and qualitatively. Results indicate that the majority of young children with FAP are optimistic about pain outcomes. Children generated many types of coping strategies for Teddy's pain and adjusted their calibration of Teddy's pain tolerance dependent on the activity being performed. Early warning signs also emerged: a subset of children were pessimistic about Teddy's pain, and several children identified coping strategies that, while developmentally appropriate, could lead to excessive help seeking if not intervened upon (e.g., physician consultation and shot). The Teddy Bear Interview allows children to externalize their pain, making it a useful tool to access cognitive pain constructs in younger children. Thus, these findings highlight the importance of early intervention for childhood FAP.

Social Support and Internalizing Psychopathology in Transgender Youth

Although increasing numbers of children have socially transitioned to live in line with their gender identities, little is known about factors associated with their wellbeing. This study examines the associations between parent-reported family, peer, and school support for a youth's gender identity, as well as an objective measure of state-level support, with parent-reported internalizing symptoms in 265 transgender youth (67.2% transgender girls, 32.8% transgender boys), ages 3-15 years (M = 9.41, SD = 2.62). Parents who reported higher levels of family, peer, and school support for their child's gender identity also reported fewer internalizing symptoms; the objective measure of state-level support was not related to internalizing symptoms. Additionally, peer and school support buffered against the association between gender-related victimization and internalizing symptoms, as reported by parents. This work demonstrates that even among transgender youth with families who supported their transitions, parents see better well-being in their children when they also see more support for the child's gender identity from family, peers, and schools.

Patient-Reported Quality of Life Following Laparotomy in a Resource-Limited Setting

INTRODUCTION

The burden of surgical diseases is high in sub-Saharan Africa. Despite limitations to surgical care access, health-related quality of life (HRQoL) data following surgical intervention are scarce.

METHODS

We performed a 3-month prospective observational study of adult patients undergoing an abdominal operation. We administered the Patient-Reported Outcome Measurement Information System (PROMIS)-25 and Index of Independence in Activities of Daily Living questionnaire preoperatively (to postoperative day [POD] #1), POD#7, and POD#30. PROMIS-25 HRQoL domains were measured and converted to standardized T-scores (median 50, minimal important clinical difference 3).

RESULTS

Of the 117 laparotomy patients who were enrolled, 89 (76.1%) were male with a median age of 39 years (IQR 27-54). Operations were primarily for intestinal volvulus (n = 30, 28.3%) and intestinal perforation (n = 29, 27.4%). We completed a total of 80 (68.4%), 95 (81.2%), and 77 (65.8%) surveys preoperatively, at POD#7, and POD#30, respectively. Preoperatively patients showed high median levels of anxiety (56), depression (60), fatigue (63), and pain interference (62), which all improved postoperatively. Mobility was poor preoperatively (31) and showed improvement during recovery but remained poor [POD#7: 32, POD#30: 39]. Pain intensity was high (10/10) preoperatively and improved to 3/10 by POD#30. Patients with complications compared to those without had clinically significant worse HRQoL in all domains measured by POD#30.

DISCUSSION

Abdominal surgery patients in a resource-limited setting present with poor HRQoL, which improves postoperatively. Mobility remained poor throughout follow-up despite improved pain scores. Our findings highlight the need for improved HRQoL and pain control among surgical patients.

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.

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.

Agreement between proxy- and self-report scores on PROMIS health-related quality of life domains in pediatric burn survivors: a National Institute on Disability, Independent Living, and Rehabilitation Research Burn Model System Study

PURPOSE

To examine agreement between pediatric burn survivor self- and caregiver proxy-report on multiple PROMIS domains and examine factors associated with differences between self- and proxy-reports.

METHODS

Children 8-17 years of age and their caregivers completed PROMIS measures (physical function, depression, peer relationships, pain interference, and anger) between 6 months and 15 years after injury. Self- and proxy-report scores were compared using Wilcoxon sign rank test, Cohen's effect size, and intraclass correlation coefficients (ICC) and by agreement across severity of symptoms based on recommended cutoffs. Ordinary least squares regression analyses examined child- (self-report score, age, gender, and ethnicity) and proxy-related (relationship to child) factors associated with score differences.

RESULTS

Two hundred and seventy four child-caregiver pairs completed the PROMIS measures. Mean child age was 13.0 (SD:3) years. Caregivers reported significantly worse scores than the child on physical function, pain, and anger (all p ≤ 0.01). The effect sizes were small across all domains except physical function. Similarly, ICCs were all of moderate agreement. The percentage of dyads in agreement by severity groups was high with only 5%-9% of pairs discordant. Only higher self-report score was associated (all p < 0.05) with greater differences across all domains in regression analyses.

CONCLUSIONS

This study supports the use of pediatric proxy PROMIS depression, physical function, peer relationships, pain interference, and anger scales in pediatric burn patients. Although agreement was moderate to good, assessing proxy-report alone as a surrogate should only be considered when self-report is not possible or practical. Caregivers typically report slightly worse severity of symptoms than children across all domains.

Impact of pediatric hypophosphatasia on behavioral health and quality of life

BACKGROUND

Hypophosphatasia (HPP) is a rare genetic disorder caused by loss-of-function mutations in the ALPL gene encoding tissue nonspecific alkaline phosphatase. It is characterized by defective bone mineralization associated with low alkaline phosphatase activity. Clinical features of pediatric HPP are highly variable, and can include premature loss of teeth, musculoskeletal problems, and impaired mobility. The effects of pediatric HPP on sleep, mood, regulation of attention and behavior, and other aspects of behavioral health have not been comprehensively studied.

METHODS

Parents of 30 children with HPP (14 females, 16 males) between the ages of 3 and 16 years (mean age = 8.0 years) enrolled in this cross-sectional survey-based study. Molecular genetic and biochemical testing as well as clinical records were reviewed to verify diagnosis of HPP. The cohort included 15 patients with a more clinically severe presentation of HPP who had received treatment with enzyme replacement therapy (asfotase alfa) and 15 children with less severe HPP who were treatment-naïve. Parents provided information regarding psychopathological comorbidity, emotional and behavioral well-being, and quality of life.

RESULTS

Clinically significant behavioral health challenges were evident in 67% of children with HPP. The most common behavioral findings included sleep disturbance and symptoms of attention deficit hyperactivity disorder (ADHD), each of which were observed ≥ 50% of individuals. Sleep disturbance, pain interference, poor behavioral regulation, and mood/anxiety symptoms were associated with reduced physical and psychosocial quality of life. Behavioral concerns were evident among children with HPP receiving asfotase alfa treatment as well as among children with clinically less severe disease who had not initiated therapy. Although most children in the cohort (77%) had age-typical development of adaptive skills, emotional and behavioral challenges were associated with weaker adaptive function.

CONCLUSIONS

Children with HPP are at increased risk for ADHD symptoms and other behavioral health challenges. There is likely an under-recognition of these findings in clinical practice.

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.

Development of a proxy-reported scale to assess motor function in infants and young children with early-onset neuromuscular disorders

AIM

To develop a novel proxy-reported scale of motor function in infants and young children with early-onset neuromuscular disorders (NMD), entitled the Proxy Motor Outcome Measure (PMOM).

DESIGN

A mixed method design was employed, applying both qualitative and quantitative research.

METHODS

A framework technique using sensitivity analyses guided the development of the most appropriate and relevant subset of items, modelled after 30 neuromuscular disease instruments/scales. The PMOM was designed based on semi-structured interviews with 16 proxies; a focus group of 11 experts in neuromuscular diseases and scale development, 10 of whom also gave quantitative data using a two-round Delphi method survey; and cognitive interviews with five proxies. These processes were conducted between January 2014-March 2019.

RESULTS

Nine themes and 32 subthemes were derived from the semi-structured interviews. Five domains and three subdomains of potential items were identified by the focus group. An initial version of the PMOM scale was created with 121 items. Using the two-round Delphi method, 43 items met agreement on pre-defined requirements. The second version of the PMOM scale included these 43 and two additional items based on expert feedback. Proxies gave 114 suggestions on cognitive interviews, 99 of which were successfully addressed by the research team. The final version of the PMOM scale included 43 items.

CONCLUSION

We developed a preliminary proxy-reported instrument, the PMOM, to evaluate motor function in infants and young children with early-onset NMD.

IMPACT

Proxies hold a wealth of knowledge on their child's motor function during early development, which may complement clinic-based motor function testing. However, there is no validated measure of motor function that incorporates the observation of proxies of infants and young children with NMD. Future work will be focused on assessing the reliability, validity and responsiveness of the PMOM scale and implementing this tool in clinical studies.

Using nationally representative percentiles to interpret PROMIS pediatric measures

PURPOSE

This study's aim was to use a representative sample of the US pediatric population to estimate percentiles for several PROMIS pediatric measures: Anger, Anxiety, Depressive Symptoms, Family Relationships, Fatigue, Global Health, Life Satisfaction, Meaning and Purpose, Pain Behavior, Pain Interference, Physical Activity, Physical Function Mobility, Physical Function Upper Extremity, Physical Stress Experiences, Positive Affect, Psychological Stress Experiences, Sleep Disturbance, Sleep Impairment, and Peer Relationships.

METHODS

We used two separate, nationally representative samples of parents and children aged 5-17 years drawn in different years from the GfK Knowledge Panel, a dual-frame online probability panel.

RESULTS

All measures that were developed using a representative sample had a median at or near the expected value of 50. For the other measures, the 50th percentile was often 10 points or more from 50. Several domains had high floors or low ceilings. No domain's percentiles completely corresponded to the percentiles associated with a normal distribution with a mean of 50 and standard deviation of 10.

CONCLUSIONS

This work allows users to interpret a child's self-reported quality of life relative to children in the US general population. When attempting to evaluate whether a child falls above or below other children in the US, one should use the values presented in this study. In addition, we recommend that users should focus on whether a child's score falls into one of a few broad severity groups rather than on specific percentile scores.

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.

Youth Anxiety About Political News

This study assessed youth anxiety about political issues and associated characteristics. Caregivers (N = 374) were recruited through Amazon Mechanical Turk and reported on their child's anxiety about 15 voting issues covered in the media since the 2016 presidential election as well as their child's psychological functioning and their own trait anxiety. For the majority of voting issues, over 50% of caregivers indicated that their child experienced at least one related worry; worries about the environment and gun violence were most common. Youth empathy and intolerance of uncertainty were each positively associated with worry about political issues but did not predict such worry after accounting for the effect of youth trait anxiety. Youth with clinical levels of generalized anxiety experienced more severe worry about political issues than did youth with minimal/subthreshold anxiety. Future studies should identify strategies for mitigating the negative impact of political news on youth with anxiety disorders.

Understanding haemophilia caregiver burden: does appraisal buffer the impact of haemophilia on caregivers over time?

Objective: The present work investigated haemophilia caregiver and patient characteristics associated with change in negative and positive aspects of caregiving. Design: Web-based survey data were collected from haemophilia A or B caregivers at baseline and two years later. Main Outcome Measures: Outcomes included Burden Summary and Positive Emotions change scores from the Haemophilia Caregiver Impact measure. Results: The sample included 323 caregivers (71% response rate; mean age 40, 90% female). Brief Appraisal Inventory Principal Components Analysis with varimax rotation yielded five scores: Awareness of Challenges, Fulfillment and Growth, Stay Positive, Social Comparison, and Interpersonal Problem-Solving. Regression analyses revealed that caregivers with more health conditions, who care for patients with increased bleeds and worse pain, and who focused more on Awareness of Challenges, Social Comparisons, and Interpersonal Problem-Solving reported worsened burden over follow-up (Adj. R² = 0.37). Prioritisation of Stay[ing] Positive and reduced emphasis on Interpersonal Problem-Solving were associated with increased Positive Emotions (Adj. R² = 0.32). Conclusion: Caregivers who focused less on a life unfettered by caregiving, comparing themselves to others, and interpersonal problem-solving and more on staying positive reported reductions in burden and improvements in positive emotions. These findings could translate to multicomponent psychoeducational interventions to help caregivers buffer haemophilia's impact.

A survey of care pathway and health-related quality of life impact for children with central precocious puberty

Objective: To describe the timeline to diagnosis for children with central precocious puberty (CPP) and evaluate their psychosocial and health-related quality of life (HRQoL).Methods: A cross-sectional survey was used to prospectively collect data from caregivers, recruited via the MAGIC Foundation, of children with CPP. The control (non-CPP) group was recruited from a national panel of parents/caregivers. After completing a screening survey, respondents completed a burden of illness survey. Respondents in both groups completed the Pediatric Quality of Life Inventory (PedsQL) and Patient-Reported Outcomes Measurement Information System (PROMIS) peer relationship instruments.Results: Responses from 142 caregivers of children with and 300 without CPP were assessed. Mean time to treatment after a child's visit to the pediatric endocrinologist was 220 days and time from onset of symptoms to initiating treatment was approximately 2 years. Responses to HRQoL inventories were all lower in children with CPP versus non-CPP. Adjusted mean (± standard error) PedsQL total (65.3 ± 1.8 versus 75.7 ± 1.2), Psychosocial Health Summary (62.4 ± 1.8 versus 73.4 ± 1.2), and Physical Health Summary (70.7 ± 2.2 versus 79.9 ± 1.5) scores were significantly lower (p < .01) in CPP versus non-CPP group. PROMIS peer relationship T score (± standard error) was numerically lower for the CPP versus non-CPP group (45.4 ± 1.0 versus 47.4 ± 0.7, p = .11).Conclusions: In clinical practice, there is a longer than expected delay between CPP symptom onset and referral to an endocrinologist and ultimate treatment. Children with CPP experience a substantial disease burden with a significant impact on emotional, social, and physical functioning compared with children without CPP.

Item generation for a proxy health related quality of life measure in very young children

BACKGROUND AND AIMS

Very young children have a relatively high prevalence of morbidity and mortality. Health care and supportive technology has improved but may require difficult choices and decisions regarding the allocation of these resources in this age group. Cost-effective analysis (CEA) can inform these decisions and thus measurement of Health-Related Quality of Life (HRQoL) is becoming increasingly important. However, the components of HRQoL are likely to be specific to infants and young children. This study aimed to develop a bank of items to inform the possible development of a new proxy report instrument.

METHODS

A review of the literature was done to define the concepts, generate items and identify measures that might be an appropriate starting point of reference. The items generated from the cognitive interviews and systematic review were subsequently pruned by experts in the field of HRQoL and paediatrics over two rounds of a Delphi study.

RESULTS

Based on the input from the different sources, the greatest need for a new HRQoL measure was in the 0-3-year age group. The item pool identified from the literature consisted of 36 items which was increased to 53 items after the cognitive interviews. The ranking of items from the first round of the Delphi study pruned this pool to 28 items for consideration. The experts further reduced this pool to 15 items for consideration in the second round. The experts also recommended that items could be merged due to their similar nature or construct. This process allowed for further reduction of items to 11 items which showed content validity and no redundancy.

CONCLUSION

The need for an instrument to measure appropriate aspects of HRQoL in infants and young children became apparent as items included in existing measures did not cover the required spectrum. The identification of the final items was based on a sound conceptual model, acceptability to stakeholders and consideration of the observability of the item selected. The pruned item bank of 11 items needs to be subject to further testing with the target population to ensure validity and reliability before a new measure can be developed.

The Validity of Patient-reported Outcome Measurement Information System (PROMIS) Parent Proxy Instruments to Assess Function in Children With Talipes Equinovarus

BACKGROUND

Idiopathic talipes equinovarus (ITEV) is a prevalent structural deformity of the foot and ankle in children. The disease-specific instrument (DSI) has commonly been used as an outcomes metric in these patients. The Patient-Reported Outcomes Measurement Information System (PROMIS) was developed to examine the quality of life across various medical conditions. PROMIS has been validated for multiple conditions; however, no studies have evaluated the use of the PROMIS in children with ITEV.

METHODS

A prospective analysis was performed whereby the 2 questionnaires were mailed out to the parents of 91 patients, aged 5 to 17 years, with ITEV. Construct validity of the PROMIS Parent Proxy Profile short forms version was assessed by comparing its domains of Mobility, Fatigue, Pain Interference, and Pain Intensity to the DSI Function domain and PROMIS domains of Anxiety, Depressive Symptoms, Peer Relationships, and Pain Intensity to DSI Satisfaction domain.

RESULTS

Thirty-one complete responses (34% response rate) were returned. The patients' current mean age was 8.8 years, 7 were female individuals, and 12 had unilateral ITEV. Bivariate correlation analysis, using Spearman correlation coefficients, demonstrated a moderate positive correlation between the DSI Function domain and the PROMIS Mobility domain (rs=0.52) and a moderate negative correlation between the DSI Function domain and the PROMIS Pain Interference domain (rs=-0.56), as well as the PROMIS Pain Intensity domain (rs=-0.75). A fair negative correlation (rs=-0.38) with PROMIS Fatigue domain was found. Correlations between the DSI Satisfaction domain and the PROMIS domains were fair or had little relationship.

CONCLUSIONS

These results provide support for the validity of the PROMIS Mobility, Pain Interference, and Pain Intensity domains in this population, however there are no items in PROMIS that can assess overall satisfaction, as with the DSI.
