Recommendations for Assessment of Social, Emotional, and Behavioral Health for the National Children's Study

The Social Emotional Behavioral (SEB) Team of the National Children's Study (NCS) was tasked with making recommendations for assessment of important aspects of social-emotional health and function in children. This paper describes the constructs recommended for assessment along with the rationale for their assessment. These constructs, representing aspects of Social Relationships, Social Capital, Temperament, Negative Affect, Externalizing Behavior, Social Competence, Self-efficacy, Self-image, Psychological well-being, Ethnic/racial Socialization, Perceived Discrimination, Sexual Orientation, Religiosity, and Perceived Stress and Resilience were identified as being critical to the understanding of children's health and development from birth to age 21.

Longitudinal Effect of Ambient Air Pollution and Pollen Exposure on Asthma Control: The Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric Asthma Study

OBJECTIVE

Although exposure to air pollution and pollen is associated with asthma exacerbation and increased health care use, longitudinal effects of fine particulate matter 2.5 (PM_2.5), ozone (O₃), and pollen exposure on asthma control status in pediatric patients are understudied. This study investigated effects of exposure to PM_2.5, O₃, and pollen on asthma control status among pediatric patients with asthma.

METHODS

A total of 229 dyads of pediatric patients with asthma and their parents were followed for 15 months. The Asthma Control and Communication Instrument was used to measure asthma control, which was reported weekly by parents during a 26-week period. PM_2.5 and O₃ data were collected from the US Environmental Protection Agency Air Quality System. Pollen data were obtained from Intercontinental Marketing Services Health. Mean air pollutant and pollen exposures within 7 days before the reporting of asthma control were used to estimate weekly exposures for each participant. Linear mixed-effects models were performed to test associations of PM_2.5, O₃, and pollen exposure with asthma control status. Sensitivity analyses were performed to evaluate the robustness of findings by different exposure monitoring days per week and distances between monitoring sites and participants' residences.

RESULTS

Elevated PM_2.5 concentration and pollen severity were associated with poorer asthma control status (P < .05), yet elevated O₃ concentration was marginally associated with better asthma control (P < .1).

CONCLUSIONS

Poorer asthma control status was associated with elevated PM_2.5 and pollen severity. Reducing harmful outdoor environmental ambient exposure may improve asthma outcomes in children and adolescents.

Assessing responsiveness over time of the PROMIS® pediatric symptom and function measures in cancer, nephrotic syndrome, and sickle cell disease

PURPOSE

Previous studies provided evidence for the validity of the PROMIS Pediatric measures in cross-sectional studies. This study evaluated the ability of the PROMIS Pediatric measures to detect change over time in children and adolescents with cancer, nephrotic syndrome (NS), or sickle cell disease (SCD).

METHODS

Participants (8-17 years) completed measures of fatigue, pain interference, anger, anxiety, depressive symptoms, mobility, upper extremity, and peer relationships at three or four time points (T1-T4). Between T1 and T2, children with cancer received chemotherapy and children with SCD experienced a pain exacerbation. Children with NS were first assessed during active disease (T2), with T3 and T4 conducted at disease remission. For the primary analysis of responsiveness, we expected better scores at T3 (recovery) compared to T2 (event) for all diseases. T1 and T4 are also expected to have better scores than T2. Linear mixed models were used and adjusted for time, gender, age, race/ethnicity, education, comorbid conditions, and disease.

RESULTS

Enrolled were 96 children with cancer, 121 children with SCD, and 127 children with NS. Fatigue, pain interference, mobility, and upper extremity scores worsened from T1 (baseline) to T2 (event) (p < 0.01), and significantly improved from T2 to T3 and T4 (p < 0.01). Similarly, anxiety and depressive symptoms significantly improved from T2 to T3 and T4 (p < 0.01).

CONCLUSIONS

This study provides evidence for the responsiveness of seven PROMIS Pediatric measures to clinical disease state in three chronic illnesses. The findings support use of PROMIS Pediatric measures in clinical research.

Responsiveness of the PROMIS® measures to changes in disease status among pediatric nephrotic syndrome patients: a Midwest pediatric nephrology consortium study

BACKGROUND

Nephrotic syndrome represents a condition in pediatric nephrology typified by a relapsing and remitting course, proteinuria and the presence of edema. The PROMIS measures have previously been studied and validated in cross-sectional studies of children with nephrotic syndrome. This study was designed to longitudinally validate the PROMIS measures in pediatric nephrotic syndrome.

METHODS

One hundred twenty seven children with nephrotic syndrome between the ages of 8 and 17 years participated in this prospective cohort study. Patients completed a baseline assessment while their nephrotic syndrome was active, a follow-up assessment at the time of their first complete proteinuria remission or study month 3 if no remission occurred, and a final assessment at study month 12. Participants completed six PROMIS measures (Mobility, Fatigue, Pain Interference, Depressive Symptoms, Anxiety, and Peer Relationships), the PedsQL version 4.0, and two global assessment of change items.

RESULTS

Disease status was classified at each assessment: nephrotic syndrome active in 100% at baseline, 33% at month 3, and 46% at month 12. The PROMIS domains of Mobility, Fatigue, Pain Interference, Depressive Symptoms, and Anxiety each showed a significant overall improvement over time (p < 0.001). When the PROMIS measures were compared to the patients' global assessment of change, the domains of Mobility, Fatigue, Pain Interference, and Anxiety consistently changed in an expected fashion. With the exception of Pain Interference, change in PROMIS domain scores did not correlate with changes in disease activity. PROMIS domain scores were moderately correlated with analogous PedsQL domain scores.

CONCLUSION

This study demonstrates that the PROMIS Mobility, Fatigue, Pain Interference, and Anxiety domains are sensitive to self-reported changes in disease and overall health status over time in children with nephrotic syndrome. The lack of significant anchoring to clinically defined nephrotic syndrome disease active and remission status may highlight an opportunity to improve the measurement of HRQOL in children with nephrotic syndrome through the development of a nephrotic syndrome disease-specific HRQOL measure.

Voices of children and adolescents on phase 1 or phase 2 cancer trials: A new trial endpoint?

BACKGROUND

Pediatric participants on phase 1 or phase 2 clinical trials for incurable cancer are at risk of experiencing toxicities (adverse events [AEs]) related to trial participation. Multiple AEs are subjective; thus, the real impact of trial treatment cannot be known unless patient subjective reports are solicited.

METHODS

The authors assessed the feasibility and acceptability of soliciting symptom, function, and quality of life (QOL) reports from participants aged 8 to 18 years who were enrolled on phase 1/2 clinical trials at 4 cancer centers during the first course of chemotherapy. The authors also assessed the reliability and validity of 6 self-report Patient-Reported Outcomes Measurement Information System (PROMIS) pediatric measures and 4 open-ended interview questions at 2 time points (at the time of trial enrollment [T1] and 3 to 4 weeks later [T2]).

RESULTS

The enrollment rate of 75.9% (20 participants) exceeded the feasibility criterion, and missingness of measures by person, measure, and items at T1 and T2 were lower than the acceptability criteria. New QOL themes were limited to the impact of treatment on families and being away from home, family, and friends for treatment. All but one measure at T1 met the reliability criterion and all measures did so at T2. Validity support was limited however because as theorized, mobility decreased and fatigue increased as AEs increased.

CONCLUSIONS

Soliciting and documenting symptom, function, and QOL reports from patients aged 8 to 18 years who are enrolled on a phase 1/2 clinical trial is feasible and acceptable to participants, particularly when embedded in trials. Reliable and valid findings can result, making patient self-reported outcomes a possible new trial endpoint. Cancer 2017;123:3799-3806. © 2017 American Cancer Society.

Determinants of longitudinal health-related quality-of-life change in children with asthma from low-income families: a report from the PROMIS® Pediatric Asthma Study

BACKGROUND

How the longitudinal asthma control status and other socio-demographic factors influence the changes of health-related quality of life (HRQOL) among asthmatic children, especially from low-income families, has not been fully investigated.

OBJECTIVES

This study aimed to describe the trajectories of asthma-specific HRQOL over 15 months and examine the effect of asthma control status on HRQOL by taking socio-demographic factors into consideration.

METHODS

A total of 229 dyads of asthmatic children and their parents enroled in public insurance programs were recruited for assessing asthma control status and HRQOL over four time points of assessment. Asthma control status was measured using the Asthma Control and Communication Instrument, and asthma-specific HRQOL was assessed using the Patient-Reported Outcomes Measurement Information System's Pediatric Asthma Impact Scale. Latent growth models (LGMs) were applied to examine the trajectory of HRQOL and the factors contributing to the changes of HRQOL.

RESULTS

Unconditional LGM revealed that HRQOL was improved over time. Conditional LGM suggested that accounting for asthma control and participants' socio-demographic factors, the variation in the initial level of HRQOL was significant, yet the rate of change was not. Conditional LGM also revealed that poorly controlled asthma status was associated with poor HRQOL at each time point (P's < 0.05). Lower parental education was associated with lower baseline HRQOL (P < 0.05). Hispanic children had a larger increase in HRQOL over time (P < 0.01) than non-Hispanic White children.

CONCLUSIONS

Vulnerable socio-demographic characteristics and poorly controlled asthma status affect HRQOL in children. This finding encourages interventions to improve asthma control status and HRQOL in minority children.

Responsiveness of PROMIS® Pediatric Measures to Hospitalizations for Sickle Pain and Subsequent Recovery

BACKGROUND

The Patient-Reported Outcomes Measurement Information System(®) (PROMIS(®) ) created pediatric self-report scales measuring a variety of health attributes (domains), but their responsiveness to changes in health status has not yet been determined in children with sickle cell disease (SCD).

PROCEDURE

A convenience cohort of symptomatic SCD children, aged 8-17 years, was asked to complete PROMIS pediatric scales at an initial clinic visit, at the end of a subsequent hospitalization for sickle pain, at a subsequent clinic visit or at home 2-3 weeks after hospitalization, and at a clinic visit 1-2 years after their initial assessment.

RESULTS

A total of 121 participants (mean age 12.5 ± 3.1 years, 56.2% female) participated in the study. Pain interference and fatigue domain scores were elevated at baseline, increased substantially during hospitalization, and largely returned to baseline by the recovery period, whereas the depressive symptoms, anger, and anxiety domain scores displayed a less pronounced elevation during hospitalizations and a slower return to baseline levels. The two physical functioning scales showed a substantial decline in response to hospitalization, but only modest improvements at the recovery assessment, likely representing incomplete recovery.

CONCLUSIONS

Several PROMIS pediatric measures were responsive to changes in health status associated with occurrence and resolution of acute vaso-occlusive pain requiring hospitalization. The substantial differences in these domains during SCD-related pain exacerbations support their potential usefulness in clinical research or in clinical practice. Further studies to characterize variations in symptom patterns over time may provide insights into strategies for more effective management of sickle pain.

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.

Responsiveness to Change in PROMIS(®) Measures among Children with Asthma: A Report from the PROMIS(®) Pediatric Asthma Study

OBJECTIVE

To compare the responsiveness to change of the Patient-Reported Outcomes Measurement Information System (PROMIS(®)) asthma impact, pain interference, fatigue, depressive symptoms, mobility, and peer relationship scales to a legacy scale, the Paediatric Asthma Quality of Life Questionnaire (PAQLQ).

METHODS

Two hundred and twenty-nine child-parent dyads from public insurance programs were enrolled. PROMIS pediatric short forms (SFs) and the PAQLQ were used to measure health-related quality of life across four time points (T1-T4) over 2 years. The Asthma Control and Communication Instrument was used to measure the change in asthma control, and the Global Rating of Change (GRC) Index for breathing problems and overall health was used to measure the change in health status. Responsiveness was tested by comparing the changes in health-related quality of life with the changes in asthma control and health status over time using t tests, generalized estimating equations, and relative validity approaches. Magnitudes of the responsiveness between the Pediatric PROMIS and PAQLQ were assessed through statistical significance, Cohen's d effect size (ES), and standardized response mean (SRM).

RESULTS

The PROMIS asthma impact scale and all PAQLQ scales exhibited significant responsiveness (p's<0.05) and small to medium ES/SRM when anchored to asthma control, GRC breathing problems, and overall health. Relative validity, especially related to change in asthma control status and GRC breathing problems, was equivalent. PROMIS pain interference, fatigue, and mobility SFs also indicated adequate responsiveness.

CONCLUSIONS

The PROMIS asthma impact SF indicated similar responsiveness to the PAQLQ scales. Due to its brevity and responsiveness, the PROMIS asthma impact SF is useful for clinical practice or research.

Longitudinal associations among asthma control, sleep problems, and health-related quality of life in children with asthma: a report from the PROMIS(®) Pediatric Asthma Study

OBJECTIVES

Few studies have investigated the complex relationship among asthma control, sleep problems, and health-related quality of life (HRQOL) among children with asthma. This study aimed to test the longitudinal effect of asthma control status on asthma-specific HRQOL through the mechanism of nighttime sleep quality and daytime sleepiness.

METHODS

The Patient-Reported Outcomes Measurement Information System (PROMIS(®)) Pediatric Asthma Study included 229 dyads of asthmatic children and their parents with two years of follow-up for assessing the change in asthma control, sleep problems, and asthma-specific HRQOL. The Asthma Control and Communication Instrument was used to measure asthma control status. Nighttime sleep quality assessment was based on difficulty falling asleep and getting up, and sleep disturbance. The Iowa Pediatric Daytime Sleeping Scale was used to assess daytime sleepiness. The PROMIS Asthma Impact Scale was used to measure asthma-specific HRQOL. Multilevel structural equation modeling was performed to quantify the direct and indirect effects of asthma control status on asthma-specific HRQOL through nighttime sleep quality and daytime sleepiness.

RESULTS

Poorer asthma control status was directly associated with lower asthma-specific HRQOL at within-subject and between-subject levels (p < 0.05); however, effects of asthma control on asthma-specific HRQOL were indirectly influenced through daytime sleepiness at the within-subject level (p < 0.05), and through nighttime sleep quality and daytime sleepiness at the between-subject level (p < 0.05).

CONCLUSIONS

Asthma control status is associated with asthma-specific HRQOL, and this association is mediated by nighttime sleep quality and daytime sleepiness. Clinicians should address sleep problems related to asthma control to improve HRQOL for asthmatic children.

Mode effects between computer self-administration and telephone interviewer-administration of the PROMIS(®) pediatric measures, self- and proxy report

OBJECTIVE

To test equivalence of scores obtained with the PROMIS(®) pediatric Depressive Symptoms, Fatigue, and Mobility measures across two modes of administration: computer self-administration and telephone interviewer-administration. If mode effects are found, to estimate the magnitude and direction of the mode effects.

METHODS

Respondents from an internet survey panel completed the child self-report and parent proxy-report versions of the PROMIS(®) pediatric Depressive Symptoms, Fatigue, and Mobility measures using both computer self-administration and telephone interviewer-administration in a crossed counterbalanced design. Pearson correlations and multivariate analysis of variance were used to examine the effects of mode of administration as well as order and form effects.

RESULTS

Correlations between scores obtained with the two modes of administration were high. Scores were generally comparable across modes of administration, but there were some small significant effects involving mode of administration; significant differences in scores between the two modes ranged from 1.24 to 4.36 points.

CONCLUSIONS

Scores for these pediatric PROMIS measures are generally comparable across modes of administration. Studies planning to use multiple modes (e.g., self-administration and interviewer-administration) should exercise good study design principles to minimize possible confounding effects from mixed modes.

The impact of disease duration on quality of life in children with nephrotic syndrome: a Midwest Pediatric Nephrology Consortium study

BACKGROUND

The Patient Reported Outcomes Measurement Information System (PROMIS) II is a prospective study that evaluates patient reported outcomes in pediatric chronic diseases as a measure of health-related quality of life (HRQOL). We have evaluated the influence of disease duration on HRQOL and, for the first time, compared the findings of the PROMIS measures to those of the PedsQL™ 4.0 Generic Scales (PedsQL) from the PROMIS II nephrotic syndrome (NS) longitudinal cohort.

METHODS

This was a prospective study in which 127 children (age range 8-17 years) with active NS from 14 centers were enrolled. Children with active NS defined as the presence of nephrotic range proteinuria (>2+ urinalysis and edema or urine protein/creatinine ratio >2 g/g) were eligible. Comparisons were made between children with prevalent (N = 67) and incident (N = 60) disease at the study enrollment visit.

RESULTS

The PROMIS scores were worse in prevalent patients in the domains of peer relationship (p = 0.01) and pain interference (p < 0.01). The PedsQL showed worse scores in prevalent patients for social functioning (p < 0.01) and school functioning (p = 0.03). Multivariable analyses showed that prevalent patients had worse scores in PROMIS pain interference (p = 0.02) and PedsQL social functioning (p < 0.01).

CONCLUSION

The PROMIS measures detected a significant impact of disease duration on HRQOL in children, such that peer relationships were worse and pain interfered with daily life to a greater degree among those with longer disease duration. These findings were in agreement with those for similar domains in the PedsQL legacy instrument.

Using item response theory to enrich and expand the PROMIS® pediatric self report banks

Background

The primary objective was to enhance the content coverage of some of the pediatric self-report item banks for ages 8–17 years from the National Institutes of Health (NIH) Patient Reported Outcomes Measurement Information System (PROMIS^®), and extend the range of precise measurement to higher levels of physical functioning.

Methods

Data from 1,419 pediatric patients with cancer, chronic kidney disease, obesity, rehabilitation needs, rheumatic disease, and sickle cell disease were combined with item responses from the original standardization sample of 3,048 children to calibrate new items for the pediatric PROMIS Anger, Anxiety, Depressive Symptoms, Pain Interference, Fatigue, and physical functioning Upper Extremity and Mobility scales. Simultaneous or concurrent calibration using the graded item response theory model placed all of the items on the same scale.

Results

Twenty-two of 28 potential new items were added across the seven scales. A recommended short form was proposed for the Anger scale, and the recommended short forms for the Anxiety and Depressive Symptoms scales were revised. Unfortunately, we were not particularly successful at extending the range of measurement for the physical functioning banks.

Conclusions

The present study expanded PROMIS pediatric item banks to add new content and to increase the range of measurement. Using item response theory, the banks were revised and expanded without changing the underlying scale of measurement. For Anger, Anxiety, and Depressive Symptoms, we successfully added new content that may render those banks more robust and flexible.

Acoustic and aerodynamic measures of the voice during pregnancy

BACKGROUND

Known influences of sex hormones on the voice would suggest pregnancy hormones could have an effect, yet studies using acoustic measures have not indicated changes. Additionally, no examination of the voice before the third trimester has been reported. Effect of pregnancy on the voice is relatively unexplored yet could be quite relevant to female speakers and singers.

OBJECTIVES/HYPOTHESIS

It is possible that spectral and aerodynamic measures would be more sensitive to tissue-level changes caused by pregnancy hormones.

DESIGN/METHODS

In this first longitudinal study of a 32-year-old woman's pregnancy, weekly voice samples were analyzed for acoustic (fundamental frequency, perturbation ratios of shimmer and jitter, Harmonic-to-Noise Ratio, spectral measures, and maximum phonation time) and aerodynamic (average airflow, peak flow, AC/DC ratio, open quotient, and speed quotient) parameters.

RESULTS

All measures appeared generally stable during weeks 11-39 of pregnancy compared with 21 weeks postpartum. Slight decrease in minimum airflow and open speed quotient may reflect suspected vocal fold tissue changes.

CONCLUSIONS

It is recommended that future studies monitor and test correlations among hormone levels, visual analyses of vocal fold mucosa, aerodynamic function, and glottal efficiency.

PROMIS Pediatric Peer Relationships Scale: development of a peer relationships item bank as part of social health measurement

OBJECTIVE

This study's objective was to develop a measure of social health using item response theory as part of the Patient Reported Outcomes Measurement Information System (PROMIS).

METHODS

After candidate items were generated from review of prior literature, focus groups, expert input, and cognitive interviews, items were administered to youth aged 8-17 as part of the PROMIS pediatric large scale testing. Exploratory and confirmatory factor analyses were used to assess dimensionality and to identify instances of local dependence. Items that met the unidimensionality criteria were subsequently calibrated using Samejima's Graded Response Model. Differential item functioning was examined by gender and age.

RESULTS

The sample included 3,048 youth who completed the questionnaire (51.8% female, 60% white, and 22.7% with chronic illness). The initial conceptualization of social function and sociability did not yield unidimensional item banks. Rather, factor analysis revealed dimensions contrasting peer relationships and adult relationships. The analysis also identified dimensions formed by responses to positively versus negatively worded items. The resulting 15-item bank measures quality of peer relationships and has strong psychometric characteristics as a full bank or an 8-item short form.

CONCLUSIONS

The PROMIS pediatric peer relationships scale demonstrates good psychometric characteristics and addresses an important aspect of child health.

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

OBJECTIVE

The objective of the present study is to describe the extension of the National Institutes of Health Patient-Reported Outcomes Measurement Information System (PROMIS(®)) pediatric parent proxy-report item banks for parents of children ages 5-7 years, and to investigate differential item functioning (DIF) between the data obtained from parents of 5-7-year-old children with the data obtained from parents of 8-17 year-old children in the original construction of the scales.

METHODS

Item response theory (IRT) analyses of DIF were conducted comparing data from the 5-7 age group with data from the established scales for ages 8-17 across 5 generic health domains (physical functioning, pain, fatigue, emotional health, and social health) and asthma.

RESULTS

IRT DIF analyses revealed that the majority of the items functioned similarly with responses from parents of younger and older children. A small number of items were removed from the item bank for younger children, and a few items that exhibited statistical DIF were retained in the pools with the caveat that they should not be used in studies that involve comparisons of younger children with older children.

CONCLUSIONS

The study confirms that most of the items in the PROMIS parent proxy-report item banks can be used with parents of children ages 5-7. It is anticipated that these new scales will have application for younger pediatric populations when pediatric self-report is not feasible.

Gaining the PROMIS perspective from children with nephrotic syndrome: a Midwest pediatric nephrology consortium study

Background and objectives

Nephrotic syndrome (NS) represents a common disease in pediatric nephrology typified by a relapsing and remitting course and characterized by the presence of edema that can significantly affect the health-related quality of life in children and adolescents. The PROMIS pediatric measures were constructed to be publically available, efficient, precise, and valid across a variety of diseases to assess patient reports of symptoms and quality of life. This study was designed to evaluate the ability of children and adolescents with NS to complete the PROMIS assessment via computer and to initiate validity assessments of the short forms and full item banks in pediatric NS. Successful measurement of patient reported outcomes will contribute to our understanding of the impact of NS on children and adolescents.

Design

This cross-sectional study included 151 children and adolescents 8-17 years old with NS from 16 participating institutions in North America. The children completed the PROMIS pediatric depression, anxiety, social-peer relationships, pain interference, fatigue, mobility and upper extremity functioning measures using a web-based interface. Responses were compared between patients experiencing active NS (n = 53) defined by the presence of edema and patients with inactive NS (n = 96) defined by the absence of edema.

Results

All 151 children and adolescents were successfully able to complete the PROMIS assessment via computer. As hypothesized, the children and adolescents with active NS were significantly different on 4 self-reported measures (anxiety, pain interference, fatigue, and mobility). Depression, peer relationships, and upper extremity functioning were not different between children with active vs. inactive NS. Multivariate analysis showed that the PROMIS instruments remained sensitive to NS disease activity after adjusting for demographic characteristics.

Conclusions

Children and adolescents with NS were able to successfully complete the PROMIS instrument using a web-based interface. The computer based pediatric PROMIS measurement effectively discriminated between children and adolescents with active and inactive NS. The domain scores found in this study are consistent with previous reports investigating the health-related quality of life in children and adolescents with NS. This study establishes known-group validity and feasibility for PROMIS pediatric measures in children and adolescents with NS.

PROMIS pediatric measures in pediatric oncology: valid and clinically feasible indicators of patient-reported outcomes

BACKGROUND

Establishing the ability of children and adolescents with cancer to complete the NIH-sponsored PROMIS pediatric measures electronically and the preliminary validity estimates of the measures (both full item banks and short forms) in pediatric oncology will contribute to our knowledge of the impact of cancer treatment on these young patients.

PROCEDURES

A total of 203 8- to 17-year olds were administered eight PROMIS pediatric measures in a cross-sectional study design to establish known-group validity. Of the 200 who completed all or most of the items, a slight majority were male (55.5%) and white (54%). Patients were either undergoing treatment for cancer (n = 93) or in survivorship following treatment for cancer (n = 107). Measures were completed using computer interface during an in-person interaction with researchers.

RESULTS

Only 3 of 203 participants did not complete the PROMIS pediatric measures. As hypothesized, participants in treatment were significantly different (worse) on parent-reported clinical indicators (blood counts, fatigue, and appetite) and on seven self-reported measures (depression, anxiety, peer relationships, pain interference, fatigue, upper extremity function, and mobility) from participants in survivorship. Females reported worse fatigue, anger, and pain interference than males. Worse patient-reported outcomes for patients in active treatment persisted after adjusting for potential confounding variables.

CONCLUSIONS

Children and adolescents in treatment for cancer or in survivorship and ranging from 8 to 17 years of age can complete multiple PROMIS pediatric measures using a computer interface during an outpatient clinic visit or inpatient admission. Findings establish known-group validity for PROMIS pediatric measures in pediatric oncology.

Promising insights into the health related quality of life for children with severe obesity

BACKGROUND

Childhood obesity is a growing health concern known to adversely affect quality of life in children and adolescents. The Patient Reported Outcomes Measurement Information System (PROMIS) pediatric measures were developed to capture child self-reports across a variety of health conditions experienced by children and adolescents. The purpose of this study is to begin the process of validation of the PROMIS pediatric measures in children and adolescents affected by obesity.

METHODS

The pediatric PROMIS instruments were administered to 138 children and adolescents in a cross-sectional study of patient reported outcomes in children aged 8-17 years with age-adjusted body mass index (BMI) greater than the 85th percentile in a design to establish known-group validity. The children completed the depressive symptoms, anxiety, anger, peer relationships, pain interference, fatigue, upper extremity, and mobility PROMIS domains utilizing a computer interface. PROMIS domains and individual items were administered in random order and included a total of 95 items. Patient responses were compared between patients with BMI 85 to<99th percentile versus ≥99th percentile.

RESULTS

136 participants were recruited and had all necessary clinical data for analysis. Of the 136 participants, 5% ended the survey early resulting in missing domain scores at the end of survey administration. In multivariate analysis, patients with BMI ≥ 99th percentile had worse scores for depressive symptoms, anger, fatigue, and mobility (p<0.05). Parent-reported exercise was associated with better scores for depressive symptoms, anxiety, and fatigue (p<0.05).

CONCLUSIONS

Children and adolescents ranging from overweight to severely obese can complete multiple PROMIS pediatric measures using a computer interface in the outpatient setting. In the 5% with missing domain scores, the missing scores were consistently found in the domains administered last, suggesting the length of the assessment is important. The differences in domain scores found in this study are consistent with previous reports investigating the quality of life in children and adolescents with obesity. We show that the PROMIS instrument represents a feasible and potentially valuable instrument for the future study of the effect of pediatric obesity on quality of life.

Development of six PROMIS pediatrics proxy-report item banks

Background

Pediatric self-report should be considered the standard for measuring patient reported outcomes (PRO) among children. However, circumstances exist when the child is too young, cognitively impaired, or too ill to complete a PRO instrument and a proxy-report is needed. This paper describes the development process including the proxy cognitive interviews and large-field-test survey methods and sample characteristics employed to produce item parameters for the Patient Reported Outcomes Measurement Information System (PROMIS) pediatric proxy-report item banks.

Methods

The PROMIS pediatric self-report items were converted into proxy-report items before undergoing cognitive interviews. These items covered six domains (physical function, emotional distress, social peer relationships, fatigue, pain interference, and asthma impact). Caregivers (n = 25) of children ages of 5 and 17 years provided qualitative feedback on proxy-report items to assess any major issues with these items. From May 2008 to March 2009, the large-scale survey enrolled children ages 8-17 years to complete the self-report version and caregivers to complete the proxy-report version of the survey (n = 1548 dyads). Caregivers of children ages 5 to 7 years completed the proxy report survey (n = 432). In addition, caregivers completed other proxy instruments, PedsQL™ 4.0 Generic Core Scales Parent Proxy-Report version, PedsQL™ Asthma Module Parent Proxy-Report version, and KIDSCREEN Parent-Proxy-52.

Results

Item content was well understood by proxies and did not require item revisions but some proxies clearly noted that determining an answer on behalf of their child was difficult for some items. Dyads and caregivers of children ages 5-17 years old were enrolled in the large-scale testing. The majority were female (85%), married (70%), Caucasian (64%) and had at least a high school education (94%). Approximately 50% had children with a chronic health condition, primarily asthma, which was diagnosed or treated within 6 months prior to the

interview. The PROMIS proxy sample scored similar or better on the other proxy instruments compared to normative samples.

Conclusions

The initial calibration data was provided by a diverse set of caregivers of children with a variety of common chronic illnesses and racial/ethnic backgrounds. The PROMIS pediatric proxy-report item banks include physical function (mobility n = 23; upper extremity n = 29), emotional distress (anxiety n = 15; depressive symptoms n = 14; anger n = 5), social peer relationships (n = 15), fatigue (n = 34), pain interference (n = 13), and asthma impact (n = 17).

Transactional processes in child disruptive behavior and maternal depression: a longitudinal study from early childhood to adolescence

Although much has been written about the utility of applying Sameroff and Chandler's transactional perspective to the study of child psychopathology, relatively few researchers have used such an approach to trace the emergence of child problem behavior from infancy to adolescence. Using a sample of 289 male toddlers from predominantly low-income families, the current study examined associations between various forms of early child disruptive behavior, subsequent trajectories of maternal depressive symptoms over the course of 8 years, and adolescent problem behavior. Results indicated that early child noncompliance was the most robust predictor of more chronic and elevated trajectories of maternal depression, which in turn discriminated teacher and youth reports of adolescent antisocial behavior but not internalizing symptoms. The findings were consistent with transactional perspectives of developmental psychopathology that have emphasized the dynamic interplay between child and parent characteristics.

Reciprocal models of child behavior and depressive symptoms in mothers and fathers in a sample of children at risk for early conduct problems

Although much has been written about transactional models in the study of parenting practices, relatively few researchers have used this approach to examine how child behavior might be related to parental well-being. This study used latent growth curve modeling to test transactional models of age 2 child noncompliance, parental depressive symptoms, and age 4 internalizing and externalizing behaviors using a subsample of families in the Early Steps Multisite Study. In unconditional models, maternal depressive symptoms showed a linear decrease from child ages 2 to 4, whereas paternal depression did not show significant change. Observed child noncompliance at age 2 showed significant associations with concurrent reports of maternal depressive symptoms and trend-level associations with paternal depressive symptoms. For both parents, higher levels of initial depressive symptoms were related to increased age 4 child internalizing behaviors. The findings provide support for reciprocal process models of parental depression and child behavior, and this study is one of the first to present empirical evidence that fathers' depressive symptoms have bidirectional associations with their children's behavior in early childhood.

Reciprocal associations between boys' externalizing problems and mothers' depressive symptoms

Although much has been written about the utility of applying transactional models to the study of parenting practices, relatively few researchers have used such an approach to examine how children influence maternal well-being throughout their development. Using a sample of males from predominantly low-income families, the current study explored reciprocal relations between boys' overt disruptive behavior (boys' ages 5 to 10 years) and maternal depressive symptoms. We then examined this model with youth-reported antisocial behaviors (ASB) and maternal depressive symptoms when the boys were older, ages 10 to 15. In middle childhood, evidence was found for both maternal and child effects from boys' ages 5 to 6 using both maternal and alternative caregiver report of child aggressive behavior. In the early adolescence model, consistent maternal effects were found, and child effects were evident during the transition to adolescence (boys' ages 11 to 12). The findings are discussed in reference to reciprocal models of child development and prevention efforts to reduce both maternal depression and the prevalence of child antisocial behavior.
