Health-Related Quality of Life and Cognitive Functioning from the Perspective of Parents of School-Aged Children with Asperger’s Syndrome Utilizing the PedsQL™

Physician and informal care use explained by the Pediatric Quality of Life Inventory (PedsQL) in children with suspected genetic disorders

PURPOSE

To examine associations between Pediatric Quality of Life Inventory (PedsQL) 4.0 Generic Core Scales and PedsQL Infant Scales with formal health care resource utilization (HCRU) and informal caregiver burden.

METHODS

We studied a pediatric cohort of 837 patients (median age: 8.4 years) with suspected genetic disorders enrolled January 2019 through July 2021 in the NYCKidSeq program for diagnostic sequencing. Using linked ~ nine-month longitudinal survey and physician claims data collected through May 2022, we modeled the association between baseline PedsQL scores and post-baseline HCRU (median follow-up: 21.1 months) and informal care. We also assessed the longitudinal change in PedsQL scores with physician services using linear mixed-effects models.

RESULTS

Lower PedsQL total and physical health scores were independently associated with increases in 18-month physician services, encounters, and weekly informal care. Comparing low vs. median total scores, increases were 10.6 services (95% CI: 1.0-24.6), 3.3 encounters (95% CI: 0.5-6.8), and $668 (95% CI: $350-965), respectively. For the psychosocial domain, higher scores were associated with decreased informal care. Based on adjusted linear mixed-effects modeling, every additional ten physician services was associated with diminished improvement in longitudinal PedsQL total score trajectories by 1.1 point (95% confidence interval: 0.6-1.6) on average. Similar trends were observed in the physical and psychosocial domains.

CONCLUSION

PedsQL scores were independently associated with higher utilization of physician services and informal care. Moreover, longitudinal trajectories of PedsQL scores became less favorable with increased physician services. Adding PedsQL survey instruments to conventional measures for improved risk stratification should be evaluated in further research.

Cross-cultural adaptation, reliability, and validity of the Turkish Pediatric Quality of Life Inventory-Cognitive Functioning Scale (PedsQLTM-CFS) in children with cancer

The Pediatric Quality of Life Inventory-Cognitive Functioning Scale (PedsQLTM-CFS) was developed as a brief, general, symptom-specific tool to measure cognitive function. The 6-item PedsQL™ Cognitive Functioning Scale and PedsQL 3.0 Cancer Module answered 369 parents and 330 children with 5-18 years. Parents also completed Behavior Rating Inventory of Executive Function (BRIEF). The PedsQL™ Cognitive Functioning Scale evidenced excellent reliability (parent proxy-report α = 0.980/Fleiss Kappa: 0.794; children self-report α = 0.963/Fleiss Kappa: 0.790). Both child self-report and parent proxy-report PedsQL™ Cognitive Functioning Scale scores exhibited significant correlations with all parent-report BRIEF summary and subscale scores (p < .05). Both child self-report and parent proxy-report PedsQL™ Cognitive Functioning Scale scores exhibited significant correlations with PedsQL 3.0 Cancer Module total score and subscale scores (p < .05). The PedsQLTM-CFS can be used in high-risk populations with substantial to perfect reliability, both in regards to total/subcategory scores as well as in children with cancer.

Perceptions of Parents/Caregivers About the Impact of Oral Conditions on the Quality of Life of Children and Adolescents with Autism Spectrum Disorder

PURPOSE

To investigate the perceptions of parents/caregivers about the impact of oral conditions on the oral health-related quality of life (OHRQoL) of children/adolescents with autism spectrum disorder (ASD) compared to the perceptions of parents/caregivers of children/adolescents without ASD.

METHODS

A comparative cross-sectional study was conducted involving 80 children/adolescents with ASD three to 16 years of age matched by sex and age with 80 children/adolescents without ASD and their parents/caregivers. Clinical examinations were performed for the diagnosis of dental caries experience (DMFT/dmft), clinical consequences of untreated dental caries (PUFA/pufa), visible plaque (VPI), bleeding on probing (BPI), malocclusion and traumatic dental injury (TDI). Parents/caregivers answered a questionnaire addressing sociodemographic characteristics and the Brazilian version of the Parental-Caregiver Perceptions Questionnaire (P-CPQ), which measures OHRQoL from the perspective of parents/caregivers. Data analysis involved the Wilcoxon test, chi-squared test and Poisson regression.

RESULTS

Dental caries experience impacted OHRQoL in the group with ASD regarding the total P-CPQ score (p < 0.001) as well as the "oral symptoms" (p = 0.011) and "wellbeing" (p < 0.011) domains. No differences were found between the perceptions of parents/caregivers of children/adolescents with ASD and perceptions of parents/caregivers of children/adolescents without ASD (p = 0.721).

CONCLUSION

Dental caries experience can have a negative impact on the OHRQoL of children/adolescents with ASD.

Convergent Validity of Myheartsmap: A Pediatric Psychosocial Health Screening Tool

Recognition of pediatric mental health concerns often depends on assessment by parents, educators, and primary care professionals. Therefore, a psychosocial screening instrument suitable for routine use in schools and primary care is needed. The Pediatric Quality of Life (PedsQL) and the Strengths and Difficulties Questionnaire (SDQ) are widely used for screening but lack adolescent-specific mental health measures. MyHEARTSMAP is an instrument assessing aspects of youth psychosocial health via four domains: Psychiatry, Function, Social, and Youth Health. We evaluated MyHEARTSMAP convergent validity with PedsQL and SDQ among 122 child-parent dyads participating in a larger concussion study. Convergent validity was assessed via correlations: MyHEARTSMAP Psychiatry and Function domains correlated strongly (r ≥ 0.44) and Social domain correlated weakly (r ≤ 0.25) to corresponding PedsQL and SDQ subscales, while Youth Health domain correlated moderately (r ≥ 0.31) to the tools' total scales. In conclusion, MyHEARTSMAP converges with PedsQL and SDQ, and benefits from the inclusion of adolescent-specific psychosocial measures.

A Psychometric Evaluation of the Quality of Life for Children with Autism Spectrum Disorder Scale

Our purpose in this study was to validate the Quality of Life for Children with Autism Spectrum Disorder scale. We first conducted an exploratory factor analysis to examine the factor structure. Results suggested that a three-factor model (Interpersonal Relationships, Self-Determination, and Emotional Well-Being) should be retained. Next, we conducted a confirmatory factor analysis to compare a higher-order factor model and additional models. Results showed acceptable model fit for the higher-order factor model. The scale had excellent reliability (α = .90) for the overall scale and for the three subscales (Interpersonal Relationships, α = .87; Self-Determination, α = .81; and Emotional Well-Being, α = .66). The 16-item scale showed convergent and divergent validity. Implications for future research and practice are discussed.

Associations between domains of health-related quality of life and comorbid emotional and behavioral problems in youth with autism spectrum disorder

BACKGROUND

Health-related quality of life (HRQoL) can be used as a measure of the impact of a particular disorder on one's daily functioning. Previous studies have found that comorbid psychiatric disorders in children and adolescents with autism spectrum disorder (ASD) are associated with poorer HRQoL than ASD alone. Less is known about potential associations between specific symptoms of comorbid psychopathology (i.e., emotional and behavioral problems) and domains of functioning or HRQoL in youth with ASD.

METHOD

Participants were 470 children with ASD 2-14 years old recruited from one of three sites. Hierarchical multiple regressions were conducted with Pediatric Quality of Life Inventory 4.0 (PedsQL; Varni et al., 2001) HRQoL domains of physical functioning, emotional functioning, school functioning, and social functioning as the dependent variables. Covariates were entered at step 1, followed by the independent variables of interest at step 2: irritability, social withdrawal, stereotypic behavior, hyperactivity/noncompliance, and inappropriate speech.

RESULTS

The study found that increased irritability was associated with poorer emotional and physical functioning and that greater social withdrawal was associated with worse social functioning. Furthermore, findings showed that more hyperactivity/noncompliance was associated with worse school functioning.

CONCLUSIONS

Results demonstrated that certain emotional and behavioral symptoms are differentially associated with domains of HRQoL. This indicates that comorbid emotional and behavioral problems should be considered when measuring HRQoL in children with ASD. It also suggests that treating comorbid emotional/behavioral problems could improve HRQoL and functioning in certain domains for this population.

Quality of Life Changes during the COVID-19 Pandemic for Caregivers of Children with ADHD and/or ASD

The COVID-19 pandemic has presented many challenges to caregivers of children. Families with children with attention-deficit/hyperactivity disorder (ADHD) and/or autism spectrum disorder (ASD) are an understudied but potentially vulnerable population to changes during the outbreak. As such, the aim of this study was to contrast quality of life for caregivers of children with ADHD and/or ASD, before and during the pandemic, compared to caregivers of neurotypical (NT) children. Total, Parent Health-Related Quality of Life, and Family Functioning Summary Scores from the Family Impact Module of the Pediatric Quality of Life InventoryTM were contrasted among caregivers of children with ADHD, ASD, comorbid ADHD and ASD, and NT development. For all scores, caregivers of ADHD and/or ASD children reported lower quality of life, both before and during the pandemic, in comparison to caregivers of NT children. For all diagnoses, quality of life decreased during the pandemic, but caregivers of children with ADHD and/or ASD reported a greater decrease in quality of life than caregivers for NT children. There are limitations to this study in terms of the composition of the sample and the survey methodology, but we are able to conclude that caregivers of children with ADHD and/or ASD have been disproportionately affected by the pandemic, and it is imperative that these families receive additional resources and support to improve their quality of life.

P-COSCA (Pediatric Core Outcome Set for Cardiac Arrest) in Children: An Advisory Statement From the International Liaison Committee on Resuscitation

Studies of pediatric cardiac arrest use inconsistent outcomes, including return of spontaneous circulation and short-term survival, and basic assessments of functional and neurological status. In 2018, the International Liaison Committee on Resuscitation sponsored the COSCA initiative (Core Outcome Set After Cardiac Arrest) to improve consistency in reported outcomes of clinical trials of adult cardiac arrest survivors and supported this P-COSCA initiative (Pediatric COSCA). The P-COSCA Steering Committee generated a list of potential survival, life impact, and economic impact outcomes and assessment time points that were prioritized by a multidisciplinary group of healthcare providers, researchers, and parents/caregivers of children who survived cardiac arrest. Then expert panel discussions achieved consensus on the core outcomes, the methods to measure those core outcomes, and the timing of the measurements. The P-COSCA includes assessment of survival, brain function, cognitive function, physical function, and basic daily life skills. Survival and brain function are assessed at discharge or 30 days (or both if possible) and between 6 and 12 months after arrest. Cognitive function, physical function, and basic daily life skills are assessed between 6 and 12 months after cardiac arrest. Because many children have prearrest comorbidities, the P-COSCA also includes documentation of baseline (ie, prearrest) brain function and calculation of changes after cardiac arrest. Supplementary outcomes of survival, brain function, cognitive function, physical function, and basic daily life skills are assessed at 3 months and beyond 1 year after cardiac arrest if resources are available.

Cognitive functioning, patient health communication, and worry mediate pain predictive effects on health-related quality of life in youth with sickle cell disease

OBJECTIVES

The objective was to investigate the serial mediating effects of perceived cognitive functioning, patient health communication, and disease-specific worry in the relationship between pain and overall generic health-related quality of life (HRQOL) in youth with sickle cell disease (SCD) from the patient perspective.

METHODS

The pain, cognitive functioning, communication and worry scales from the Pediatric Quality of Life Inventory (PedsQL) Sickle Cell Disease Module and the PedsQL Multidimensional Fatigue Scale, and the PedsQL 4.0 Generic Core Scales were completed in a multisite national study by 233 youth with SCD of ages 5-18. Hierarchical multiple regression and serial multiple mediator model analyses were conducted to test the mediating effects of perceived cognitive functioning, health communication, and disease-specific worry as intervening variables in the association between the pain predictor variable and overall generic HRQOL.

RESULTS

Pain predictive effects on overall generic HRQOL were serially mediated by cognitive functioning, health communication, and disease-specific worry. In predictive analytics models utilizing hierarchical multiple regression analyses with age and gender demographic covariates, pain, cognitive functioning, health communication, and worry accounted for 65% of the variance in patient-reported overall generic HRQOL (P < .001), representing a large effect size.

CONCLUSIONS

Perceived cognitive functioning, patient health communication, and disease-specific worry explain in part the mechanism of pain predictive effects on overall generic HRQOL in youth with SCD. Identifying SCD-specific pain, perceived cognitive functioning, health communication, and disease-specific worry as predictor variables of overall generic HRQOL from the patient perspective may inform clinical interventions and future patient-centered clinical research.

Quality of Life in School-Aged Youth Referred to an Autism Specialty Clinic: A Latent Profile Analysis

We examined whether different profiles of quality of life (QoL) existed among youth referred to an autism spectrum disorder (ASD) specialty clinic and, if present, determined if these groups were associated with different characteristics. Data were from parental report of 5-17 year-old youth (N = 476) who were scheduled to receive an evaluation at an ASD clinic. Parents completed questionnaires, including the Pediatric Quality of Life Inventory, assessing child and family functioning; providers reported diagnostic impressions. A latent profile analysis found five distinct groups: Low Risk, School Problems, Only Social Emotional Problems, and two Physical/Social Emotional Problems. The groups differed on clinical characteristics and family functioning. These findings have implications for more efficient and effective evaluations in service delivery systems serving complex patients.

Interventions based on early intensive applied behaviour analysis for autistic children: a systematic review and cost-effectiveness analysis

BACKGROUND

Early intensive applied behaviour analysis-based interventions are intensive interventions for autistic children that are often delivered on a one-to-one basis for 20-50 hours per week.

OBJECTIVES

To evaluate the clinical effectiveness and cost-effectiveness of early intensive applied behaviour analysis-based interventions for autistic children, based on current evidence.

METHODS

A systematic review and individual participant data meta-analysis were conducted to evaluate the clinical effectiveness of an early intensive applied behaviour analysis-based intervention for autistic children. An economic analysis included a review of existing analyses and the development of a new model.

RESULTS

Twenty studies were included in the clinical review. Individual participant data were retrieved from 15 of these studies. Results favoured the interventions when assessing adaptive behaviour after 2 years compared with treatment as usual/eclectic interventions (mean difference 7.00, 95% confidence interval 1.95 to 12.06). In analyses of cognitive ability (intelligence quotient), results favoured the interventions by approximately 10 points after 1 year (mean difference 9.16, 95% confidence interval 4.38 to 13.93) and 2 years (mean difference 14.13, 95% confidence interval 9.16 to 19.10). Evidence for other outcomes was limited and meta-analyses were generally inconclusive. There was no evidence that the effect of the interventions varied with characteristics of the children, but data were limited. Adopting a £30,000 per quality-adjusted life-year threshold, the results of the cost-effectiveness analysis indicate that early intensive applied behaviour analysis-based interventions would need to generate larger benefits or cost savings to be cost-effective. Adopting a public sector perspective and making pessimistic assumptions about long-term effects, the incremental cost-effectiveness ratio for early intensive applied behaviour analysis-based therapy compared with treatment as usual is £189,122 per quality-adjusted life-year. When optimistic assumptions are made, the incremental cost-effectiveness ratio is £46,768 per quality-adjusted life-year. Scenario analyses indicated that these interventions can potentially be cost-effective if long-term improvements persist into adulthood, or if they have significant impact on educational placement. Care should be taken when interpreting these scenarios owing to the limited data.

LIMITATIONS

All included studies were at risk of bias, there was substantial heterogeneity and effects varied considerably across studies. The effect of intervention on autism symptom severity, language development and school placement remains uncertain because of the limited data. The long-term effects are unclear owing to a lack of follow-up data.

CONCLUSIONS

This review found limited evidence that early intensive applied behaviour analysis-based interventions may improve cognitive ability and adaptive behaviour, but the long-term impact of the interventions remains unknown. The economic analysis is constrained by the limited effectiveness evidence, but suggests that these interventions are unlikely to be cost-effective unless clear long-term benefits, or a substantial change in which schools children attend, can be identified.

FUTURE WORK

Further studies into the effectiveness of early intensive applied behaviour analysis-based interventions may be warranted if they include well-defined, alternative interventions as comparators and collect relevant outcomes. Consideration should be given to future studies that not only address whether or not early intensive applied behaviour analysis-based interventions are clinically effective, but also aim to identify which components of early intensive applied behaviour analysis-based interventions might drive effectiveness.

Pediatric Quality of Life Inventory (PedsQL) in Fragile X Syndrome

To date, health related quality of life (QoL) has not been systematically evaluated in youth with fragile X syndrome (FXS), the most common single gene cause of autism and the most common inherited form of developmental disability. We describe QoL data gathered using the Pediatric Quality of Life Inventory (PedsQL) completed online by 364 parents of youth with FXS. Parents consistently reported across all gender and age groups that their children experienced the highest QoL in Physical functioning and the lowest QoL in Cognitive functioning. Overall, older children with FXS had increase QoL ratings in the domains of School and Cognitive function.

PedsQL™ Cognitive Functioning Scale in youth with epilepsy: Reliability and validity

OBJECTIVE

The objective of the study was to report on the internal consistency reliability and discriminant, concurrent and construct validity of the Pediatric Quality of Life Inventory™ (PedsQL™) Cognitive Functioning Scale as a brief generic cognitive functioning measure in youth with epilepsy.

METHODS

The 6-item PedsQL™ Cognitive Functioning Scale and 23-item PedsQL™ 4.0 Generic Core Scales were completed by 221 pediatric patients ages 5-18 years with epilepsy and 336 parents of patients ages 2-18 years in a national field test study for the PedsQL™ Epilepsy Module. Parents also completed the 86-item Behavior Rating Inventory of Executive Function (BRIEF), a widely validated measure of executive functioning.

RESULTS

The PedsQL™ Cognitive Functioning Scale evidenced excellent reliability (patient self-report α = 0.88; parent proxy-report α = 0.96), distinguished between youth with epilepsy and an age, gender, and race/ethnicity-matched healthy sample supporting discriminant validity with large effect sizes (~20-30 point score differences, P < 0.001), and demonstrated concurrent and construct validity, respectively, through large effect size intercorrelations with the BRIEF (Behavioral Regulation Index, Metacognition Index, Global Executive Composite Summary Scores rs = 0.43-0.67, P < 0.001) and the PedsQL™ Generic Core Scales (Total Scale Scores rs = 0.67-0.74, P < 0.001). Minimal clinically important difference (MCID) scores ranged from 5.92 to 8.80.

CONCLUSIONS

The PedsQL™ Cognitive Functioning Scale demonstrated excellent internal consistency reliability, discriminant, concurrent, and construct validity in youth with epilepsy and may be suitable as a brief generic patient-reported outcome (PRO) measure for clinical research, clinical trials, and routine clinical practice in pediatric epilepsy.

"Quality of life": parent and neonatologist perspectives

OBJECTIVE

To assess how physicians and families understand quality of life (QOL) for NICU patients, and to explore the feasibility of developing a standardized definition for QOL.

STUDY DESIGN

Surveys were developed and administered to neonatologists and eligible families. Quantitative analysis was conducted using standard statistical methods. Qualitative analysis was conducted using NVivo software. Focus groups were conducted with the same groups, and audio recordings were obtained and analyzed for recurring themes.

RESULTS

Both parents and physicians value QOL as a metric for guiding care in the NICU. Parents were more likely to accept higher levels of disability, while neonatologists were more likely to accept higher levels of dependence on medical equipment. In relation to infant QOL, predominant themes expressed in the parent focus groups were stress levels in the NICU, advocating as parents, and the way in which long-term outcomes were presented by the medical team; in the physician focus group, the ambiguity of predicting outcomes and thus QOL was the main theme.

CONCLUSIONS

Both parents and physicians recognize the importance of QOL in the decision-making process for critically ill infants, but the two groups differ in their assessment of what QOL means in this context. These data suggest that QOL cannot be adequately defined for standardized use in a clinical context, and as such, should be used thoughtfully by neonatologists in discussions of end- of-life care.

Effectiveness of a Multisystem Aquatic Therapy for Children with Autism Spectrum Disorders

Aquatic therapy improves motor skills of persons with Autism Spectrum Disorders (ASD), but its usefulness for treating functional difficulties needs to be verified yet. We tested effectiveness of a multisystem aquatic therapy on behavioural, emotional, social and swimming skills of children with ASD. Multisystem aquatic therapy was divided in three phases (emotional adaptation, swimming adaptation and social integration) implemented in a 10-months-programme. At post-treatment, the aquatic therapy group showed significant improvements relative to controls on functional adaptation (Vineland Adaptive Behavior Scales), emotional response, adaptation to change and on activity level (Childhood Autism Rating Scale). Swimming skills learning was also demonstrated. Multisystem aquatic therapy is useful for ameliorating functional impairments of children with ASD, going well beyond a swimming training.

Associations of Gross Motor Delay, Behavior, and Quality of Life in Young Children With Autism Spectrum Disorder

BACKGROUND

Young children with autism spectrum disorder (ASD) often have gross motor delays that may accentuate problem daytime behavior and health-related quality of life (QoL).

OBJECTIVE

The objective of this study was to describe the degree of gross motor delays in young children with ASD and associations of gross motor delays with problem daytime behavior and QoL. The primary hypothesis was that Gross motor delays significantly modifies the associations between internalizing or externalizing problem daytime behavior and QoL.

DESIGN

This study used a cross-sectional, retrospective analysis.

METHODS

Data from 3253 children who were 2 to 6 years old and who had ASD were obtained from the Autism Speaks Autism Treatment Network and analyzed using unadjusted and adjusted linear regression. Measures included the Vineland Adaptive Behavior Scales, 2nd edition, gross motor v-scale score (VABS-GM) (for Gross motor delays), the Child Behavior Checklist (CBCL) (for Problem daytime behavior), and the Pediatric Quality of Life Inventory (PedsQL) (for QoL).

RESULTS

The mean VABS-GM was 12.12 (SD = 2.2), representing performance at or below the 16th percentile. After adjustment for covariates, the internalizing CBCL t score decreased with increasing VABS-GM (β = - 0.64 SE = 0.12). Total and subscale PedsQL scores increased with increasing VABS-GM (for total score: β = 1.79 SE = 0.17; for subscale score: β = 0.9-2.66 SE = 0.17-0.25). CBCL internalizing and externalizing t scores decreased with increasing PedsQL total score (β = - 0.39 SE = 0.01; β = - 0.36 SE = 0.01). The associations between CBCL internalizing or externalizing t scores and PedsQL were significantly modified by VABSGM (β = - 0.026 SE = 0.005]; β = - 0.019 SE = 0.007).

LIMITATIONS

The study lacked ethnic and socioeconomic diversity. Measures were collected via parent report without accompanying clinical assessment.

CONCLUSIONS

Cross motor delay was independently associated with Problem daytime behavior and QoL in children with ASD. Gross motor delay modified the association between Problem daytime behavior and QoL. Children with ASD and co-occurring internalizing Problem daytime behavior had greater Gross motor delays than children without internalizing Problem daytime behavior; therefore, these children may be most appropriate for early physical therapist evaluation.

The comparison of perceived health-related quality of life between Australian children with severe specific language impairment to age and gender-matched peers

BACKGROUND

Children with specific language impairment often present with multiple comorbidities, which may adversely affect both participation in play and academic performance, potentially impacting a child's health-related quality of life. This study 1) explored the suitability of the Pediatric Quality of Life Inventory™ Version 4.0 Generic Core Scales (PedsQL™) for use with a typically developing Australian control group, and 2) compared the health-related quality of life between a control group and Australian children with severe specific language impairment.

METHODS

Health-related quality of life data collected as part of a broader study of 43 children with severe specific language impairment (males = 35, age range 5-16, mean age = 8.79+/- 2.92) enrolled at a special school were used to explore previously unreported findings. Typically developing gender and age matched (+/- 3 months) peers were recruited from local schools. The PedsQL™ child self-report and proxy-report were individually or interviewer-administered to the control group as required, and then compared to the group with specific language impairment.

RESULTS

The PedsQL™ was reliable and feasible for use with the control group (N = 43, males = 35, age range = 5-16 years, mean age = 8.74+/- 2.94 years). Control group performance was as expected as per the manual. Parents of the control group scored their children significantly higher than did the children themselves on all scales except the emotional functioning scale. Both the control group children and their parents scored themselves significantly higher on all scales, compared to children with severe specific language impairment and their parents.

CONCLUSIONS

The PedsQL™ was suitable for use with the control group. Further, the recruitment of a control group provided additional clarity on the extent a severe specific language impairment impacts on an Australian child's perceived health-related quality of life, compared to the manual cut-off scores. Severe specific language impairment significantly impacts negatively on the health-related quality of life of Australian children across all domains, particularly when compared to an age and gender-matched group of peers. These results warrant the inclusion of health-related quality of life evaluations in the assessment of these children along with a multidisciplinary approach.

Health-related quality of life in congenital heart disease surgery patients in Pakistan: protocol for a mixed-methods study

INTRODUCTION

Reduced health-related quality of life (HRQOL) has been reported in postoperative patients with congenital heart disease (CHD). However, there is a paucity of data from low-income and middle-income countries (LMIC). Differences in sociodemographics and sociocultural contexts may influence HRQOL. This protocol paper describes a study exploring HRQOL in surgical patients with CHD from a tertiary hospital in Pakistan. The study findings will assist development of strategies to improve HRQOL in a resource-constrained context.

METHODS AND ANALYSIS

This prospective, concurrent triangulation, mixed-methods study aims to compare HRQOL of postsurgery patients with CHD with age-matched healthy siblings and to identify HRQOL predictors. A qualitative component aims to further understand HRQOL data by exploring the experiences related to CHD surgery for patients and parents. Participants include patients with CHD (a minimum of n~95) with at least 1-year postsurgery follow-up and no chromosomal abnormality, their parents and age-matched, healthy siblings. PedsQL 4.0 Generic Core Scales, PedsQL Cognitive Functioning Scale and PedsQL 3.0 Cardiac Module will measure HRQOL. Clinical/surgical data will be retrieved from patients' medical files. Student's t-test will be used to compare the difference in the means of HRQOL between CHD and siblings. Multiple regression will identify HRQOL predictors. A subsample of enrolled patients (n~20) and parents (n~20) from the quantitative arm will be engaged in semistructured qualitative interviews, which will be analysed using directed content analysis. Anticipated challenges include patient recruitment due to irregular follow-up compliance. Translation of data collection tools to the Urdu language and back-translation of interviews increases the study complexity.

ETHICS AND DISSEMINATION

Ethics approval has been obtained from The Aga Khan University, Pakistan (3737-Ped-ERC-15). Study findings will be published in peer-reviewed journals and presented at national and international conferences.

Associations of quality of life with health-related characteristics among children with autism

We examine whether behavioral, mental health, and physical health characteristics of children with autism are associated with baseline and change in health-related quality of life. We measured health-related quality of life with the Pediatric Quality of Life Inventory 4.0 total scores from children enrolled in the Autism Treatment Network. We used linear mixed model regressions with random slopes. Predictors of lower health-related quality of life at baseline included demographic and insurance characteristics, diagnosis, higher Child Behavior Checklist internalizing and externalizing scores, sleep problems by Children's Sleep Habits Questionnaire, seizures, gastrointestinal problems, and mental health problems. Several characteristics had different associations over time. This study demonstrates that in addition to behavioral and autism-related characteristics, physical and mental health conditions are associated with health-related quality of life in children with autism.

A comparison of children and adolescent's self-report and parental report of the PedsQL among those with and without autism spectrum disorder

PURPOSE

Children and adolescents with autism spectrum disorders (ASD) are understood to experience a reduced quality of life compared to typically developing (TD) peers. The evidence to support this has largely been derived from proxy reports, in turn which have been evaluated by Cronbach's alpha and interrater reliability, neither of which demonstrate unidimensionality of scales, or that raters use the instruments consistently. To redress this, we undertook an evaluation of the Pediatric Quality of Life Inventory™ (PedsQL), a widely used measure of children's quality of life. Three questions were explored: (1). do TD children or adolescents and their parents use the PedsQL differently; (2). do children or adolescents with ASD and their parents use the PedsQL differently, and (3). do children or adolescents with ASD and TD children or adolescents use the PedsQL differently? By using the scales differently, we mean whether respondents endorse items differently contingent by group.

METHODS

We recruited 229 children and adolescents with ASD who had an IQ greater than 70, and one of their parents, as well as 74 TD children or adolescents and one of their parents. Children and adolescents with ASD (aged 6-20 years) were recruited from special primary and secondary schools in the Amsterdam region. Children and adolescents were included based on an independent clinical diagnosis established prior to recruitment according to DSM-IV-TR criteria by psychiatrists and/or psychologists, qualified to make the diagnosis. Children or adolescents and parents completed their respective version of the PedsQL.

RESULTS

Data were analysed for unidimensionality and for differential item functioning (DIF) across respondent for TD children and adolescents and their parents, for children and adolescents with ASD and their parents, and then last, children and adolescents with ASD were compared to TD children and adolescents for DIF. Following recoding the data, the unidimensional model was found to fit all groups. We found that parents of and TD children and adolescents do not use the PedsQL differently ([Formula: see text] = 64.86, p = ns), consistent with the literature that children and adolescents with ASD and TD children and adolescents use the PedsQL similarly ([Formula: see text] = 92.22, p = ns), though their score levels may differ. However, children and adolescents with ASD and their parents respond to the PedsQL differently ([Formula: see text] = 190.22, p < 0.001) and contingently upon features of the child or adolescent.

CONCLUSIONS

We suggest this is due to children or adolescents with ASD being less forthcoming with their parents about their lives. This, however, will require additional research to confirm. Consequently, we conclude that parents of high-functioning children with ASD are unable to act as reliable proxies for their children with ASD.

Measurement properties of multidimensional patient-reported outcome measures in neurodisability: a systematic review of evaluation studies

AIM

To identify and appraise the quality of studies that primarily assessed the measurement properties of English language versions of multidimensional patient-reported outcome measures (PROMs) when evaluated with children with neurodisability, and to summarize this evidence.

METHOD

MEDLINE, Embase, PsycINFO, CINAHL, AMED, and the National Health Service Economic Evaluation Database were searched. The methodological quality of the papers was assessed using the COnsensus-based Standards for selection of health Measurement INstruments checklist. Evidence of content validity, construct validity, internal consistency, test-retest reliability, proxy reliability, responsiveness, and precision was extracted and judged against standardized reference criteria.

RESULTS

We identified 48 studies of mostly fair to good methodological quality: 37 papers for seven generic PROMs (CHIP, CHQ, CQoL, KIDSCREEN, PedsQL, SLSS, and YQOL), seven papers for two chronic-generic PROMs (DISABKIDS and Neuro-QOL), and four papers for three preference-based measures (HUI, EQ-5D-Y, and CHSCS-PS).

INTERPRETATION

On the basis of this appraisal, the DISABKIDS appears to have more supportive evidence in samples of children with neurodisability. The overall lack of evidence for responsiveness and measurement error is a concern when using these instruments to measure change, or to interpret the findings of studies in which these PROMs have been used to assess change.

Health-related quality of life from the perspective of children with severe specific language impairment

BACKGROUND

This study aimed to evaluate the feasibility and reliability of the Pediatric Quality of Life Inventory(™) 4.0 Generic Core Scales (PedsQL(™)) for use by children with severe specific language impairment (SLI) and their parent, and to explore the health-related quality of life of children with severe SLI. We hypothesized that the PedsQL(™) would be a suitable measure, and identify lower health-related quality of life compared to the healthy population sample, particularly in school and social functioning.

METHODS

Forty-three out of 61 children with severe SLI enrolled at a dedicated school from February 2010 until September 2011 agreed to participate. Children and parents completed the PedsQL(™) separately with support as required.

RESULTS

The PedsQL(™) proved to be suitable for this cohort. Children perceived themselves to be at risk of impaired social and physical functioning, rendering the total score below the population mean. Parents rated social and emotional functioning at risk of impairment, with the psychosocial and total summary score consequently below the population mean. Physical functioning had the largest child/parent difference, with children rating themselves below the cut-off score, and parents rating their children above the cut-off score.

CONCLUSIONS

This measure can be used with this group. Our group of children with severe SLI reported lower health-related quality of life than the healthy population mean as perceived by both the child and the parent. Health professionals working with children who have SLI need to consider not only a child's impairment, but also their wellbeing and participation by incorporating self- and proxy-reports into assessment in order to promote meaningful therapeutic outcomes that impact positively on a child's life.

Reliability and Validity of the Pediatric Quality of Life Inventory With Individuals With Intellectual and Developmental Disabilities

The Pediatric Quality of Life Inventory (PedsQL) measures health-related quality of life, a growing area of research, particularly among individuals with disabilities. This research is necessary to fully understand the varied needs of the population and, ultimately, ensure that those needs are being met. The current study assessed the reliability and validity of the PedsQL in individuals with intellectual and developmental disabilities, including individuals with autism spectrum disorder. Participants included 359 caregivers of children, youth, and young adults with IDD. Caregivers completed the PedsQL 4.0 Generic Core Scales questions regarding the individual's physical health and the Strengths and Difficulties Questionnaire. The PedsQL achieved excellent reliability across scales, and distinguished healthy individuals from those with chronic health conditions, as well as individuals with ASD from those without. Factor analysis confirmed a 5-factor model, with moderate to high criterion validity. The PedsQL shows sound psychometric properties and may be a useful tool to measure psychosocial functioning in this population.

Effects of equine assisted activities on autism spectrum disorder

Quality of life assessments were used in this study to determine the behavioral changes of children diagnosed with autism spectrum disorder (ASD) who participated in equine assisted activities. Behavioral changes of children with ASD participating in 9 weeks of equines assisted activities (EAA) (N = 10) were compared to behavioral changes of children who participated in a non-equine intervention (N = 8). Parents noted significant improvements in their child's physical, emotional and social functioning following the first 6 weeks of EAA. The children participating in the non-equine program also demonstrated improvement in behavior, but to a lesser degree. The favorable outcome of this study lends support for continuation of programs utilizing EAA in the treatment of children with ASD.

Informing the NHS Outcomes Framework: evaluating meaningful health outcomes for children with neurodisability using multiple methods including systematic review, qualitative research, Delphi survey and consensus meeting

Background

The identification of suitable outcome measures will improve the evaluation of integrated NHS care for the large number of children affected by neurodisability, and has the potential to encourage the provision of more appropriate and effective health care. This research sought to appraise the potential of patient-reported outcome measures (PROMs) for children and young people with neurodisability.

Aim

This research aimed (i) to identify key outcomes of health care for children with neurodisability, beyond morbidity and mortality, from the perspectives of children, parents and professionals; (ii) to critically appraise existing generic multidimensional PROMs; and (iii) to examine whether or not the key outcomes might be measured by existing PROMs. We also sought agreement on a definition of neurodisability.

Methods

Data were gathered in three main ways, (i) a systematic review identified eligible generic multidimensional PROMs and peer-reviewed studies evaluating psychometric performance using English-language questionnaires. Studies were appraised for methodological quality and psychometric performance was appraised using standard criteria. (ii) Focus groups and interviews with children and young people with neurodisability, and separately with parents, sought to identify important outcomes of NHS care, and their feedback on example PROM questionnaires. (iii) An online Delphi survey was conducted with a multidisciplinary sample of health professionals to seek agreement on appropriate NHS outcomes. In addition, we convened a consensus meeting with a small nominal group of young people, parents and professionals; the group sought agreement on a core set of important health outcomes.

Results

From the systematic review, we identified 126 papers that reported eligible evidence regarding the psychometric performance of 25 PROMs. Evidence of psychometric robustness was more favourable for a small number of PROMs: KIDSCREEN (generic), DISABKIDS (chronic-generic) and Child Health Utility 9D (preference-based measure). The Pediatric Quality of Life Inventory and KINDL offer both self-report and a proxy report version for a range of age bands, but evidence of their psychometric performance was weaker. Evidence was lacking in one or more respects for all candidate PROMs, in both general populations and those with neurodisability. Proxy reporting was found generally to be poorly correlated with self-report. Focus groups and interviews included 54 children and young people, and 53 parents. The more important health outcomes were felt to be communication, emotional well-being, pain, mobility, independence/self-care, worry/mental health, social activities and sleep. In addition, parents of children with intellectual impairment identified behaviour, toileting and safety as important outcomes. Participants suggested problems with the face validity of example PROM questionnaires for measuring NHS care. In the Delphi survey, 276 clinicians from a wide range of professions contributed to at least one of four rounds. Professionals rated pain, hearing, seeing, sleep, toileting, mobility and communication as key goals for the NHS but also identified treating neurological symptoms as important. Professionals in the Delphi survey and parents working with the research team agreed a proposed definition for neurodisability. The consensus meeting confirmed overlap between the outcomes identified as important by young people, parents and professionals, but not complete agreement.

Conclusions

There was agreement between young people, parents and professionals regarding a core suite of more important health outcomes: communication, emotional well-being, pain, mobility, independence/self-care, worry/mental health, social activities and sleep. In addition, behaviour, toileting and safety were identified as important by parents. This research suggests that it would be appropriate to measure these constructs using PROMs to assess health care. None of the candidate PROMs in the review adequately captures all of the identified constructs, and there is inadequate evidence that candidate PROMs are psychometrically robust for use across children with neurodisability. Further consultation with young people, families and professionals is warranted to support the use of PROMs to measure NHS outcomes. Research to test potential PROMs with different age groups and conditions would be valuable.

Quality of life in autism across the lifespan: a meta-analysis

Autism is a lifelong neurodevelopmental disorder, with a known impact on quality of life. Yet the developmental trajectory of quality of life is not well understood. First, the effect of age on quality of life was studied with a meta-analysis. Our meta-analysis included 10 studies (published between 2004 and 2012) with a combined sample size of 486 people with autism and 17,776 controls. Second, as there were no studies on quality of life of the elderly with autism, we conducted an empirical study on quality of life of the elderly (age range 53-83) with autism (N = 24) and without autism (N = 24). The meta-analysis showed that quality of life is lower for people with autism compared to people without autism, and that the mean effect is large (Cohen's d = -0.96). Age did not have an effect on quality of life. The study concerning the elderly with autism showed that the difference in quality of life is similar in the elderly. Age, IQ and symptom severity did not predict quality of life in this sample. Across the lifespan, people with autism experience a much lower quality of life compared to people without autism. Hence, the quality of life seemed to be independent of someone's age.

Assessment of quality of life in children and youth with autism spectrum disorder: a critical review

PURPOSE

To review the use of quality of life (QOL) measures utilised in children and youth with autism spectrum disorder (ASD).

METHODS

Relevant articles were identified through database searches using MEDLINE, CINAHL Plus with Full Text and SPORTDiscus with Full Text via EBSCO Health Database, PsycINFO and ProQuest Health and Medicine (from 2000 to May 2013). Original research articles were included that measured QOL in children and youth with ASD aged 5-20 years. Searches were limited to articles from peer-reviewed journals, in English or German, and those available in full text.

RESULTS

The search identified 1,165 titles and 13 met the inclusion criteria. The review identified a number of QOL measures used in children and youth with ASD, with the most common one being the Pediatric Quality of Life Inventory™ (PedsQL). QOL measures using self-reports were uncommon, and the reliability and validity of QOL measures were not sufficiently reported for this population. Large discrepancies in QOL scores were found between self-reports and proxy-reports. Despite the differences in study design and methodological quality, there was consistency in the results among studies; children and youth with ASD provided lower QOL scores, particularly for social domains, compared to their healthy counterparts.

CONCLUSIONS

The PedsQL is likely to be an appropriate QOL measure for use in children and youth with ASD. Future research should focus on examining the appropriateness, reliability and validity of QOL self-reports for use in this population.

Health-related quality of life in children with high-functioning autism

The health-related quality of life of school-aged children with high-functioning autism is poorly understood. The objectives of this study were to compare the health-related quality of life of children with high-functioning autism to that of typically developing peers and to compare child-self and parent-proxy reports of health-related quality of life of children. A cross-sectional study of children with high-functioning autism ( n = 30) and peers ( n = 31) was conducted using the Pediatric Quality of Life Inventory 4.0 Generic Core Scales. Children with high-functioning autism had significantly poorer health-related quality of life than peers whether reported by themselves ( p < .001) or their parents ( p < .001), although disagreement (intra-class coefficient = −.075) between children and parental scores suggested variance in points of view. This study specifically investigated health-related quality of life in children with high-functioning autism as compared to a sample of peers, from the child’s perspective. It strengthens earlier findings that children with high-functioning autism experience poorer health-related quality of life than those without this disorder and points to the importance of clinicians working with families to identify areas in a child’s life that promote or hinder their sense of well-being.

Finding out what matters: validity of quality of life measurement in young people with ASD

BACKGROUND

  Compared with other conditions there has been a lack of focus on quality of life (QoL) as an outcome measure for children and young people with Autism Spectrum Disorder (ASD). This pilot study aimed to evaluate the validity of existing QoL questionnaires for use with children with ASD aged 8-12 years.

METHODS

  A literature review (1990-2011) identified the PedsQL (Pediatric Quality of Life Inventory) and Kidscreen as robust measures used with children with neurodevelopmental disorders. These measures were completed by 10 children and 11 parents. In addition semi-structured interviews were conducted with 10 parents and four children to explore their experience of completing the QoL questionnaires.

RESULTS

  Young people with ASD, and their parents, report lower child QoL compared with a normative sample. Framework analysis of the data highlighted six key themes which may affect the validity of generic QoL measures when administered within an ASD sample and which warrant further investigation.

CONCLUSIONS

  Our results indicate that a new condition-specific measure of QoL, grounded in ASD children's own perspectives of their lives, is needed and that such a measure should assess experiences of anxiety and access to special interests when measuring QoL of children with ASD. Active involvement of young people and their families is critical for the development of a theoretical framework for QoL within ASD, and any future development of an ASD-specific measure.

Agreement in quality of life assessment between adolescents with intellectual disability and their parents

Intellectual disability affects different aspects of functioning and quality of life, as well as the ability to independently assess the quality of life itself. The paper examines the agreement in the quality of life assessments made by adolescents with intellectual disability and their parents compared with assessments made by adolescents without intellectual disability and their parents. Participants included 67 adolescents with intellectual disability and the same number of their parents. Control group consisted of 122 typically developed adolescents and an equal number of their parents. In order to assess the quality of life we used The PedsQL 4.0 Generic Core Scale questionnaire, for adolescents aged between 13 and 18 and their parents. Agreement in assessing quality of life between adolescents and parents was analyzed using t-test, Kappa Statistics and Pearson correlation. The agreement between adolescents with intellectual disability and their parents was found to be acceptable (k=0.43), while the agreement between adolescent from control group and their parents was judged to be good (k=0.84). Correlations between adolescents with intellectual disability and their parents varied across subscales from weak (r=0.31) on the physical health subscale to moderate (r=0.56) on the social subscale. Adolescents with intellectual disability were less satisfied with their social functioning. The highest agreement, as well as the lowest means value was found on the social agreement scale. Assessment of the quality of life by both adolescents and their parents provides a comprehensive insight into functioning and different aspects of quality of life in these adolescents.

Autism spectrum disorders: a review of measures for clinical, health services and cost-effectiveness applications

Autism spectrum disorders (ASDs) are characterized by impairments in social interaction, communication and behavioral functioning that can affect the health-related quality-of-life outcomes of the affected child and the family. ASDs have increased in prevalence, leading to a demand for improved understanding of the comparative effectiveness of different pharmacologic, behavioral, medical and alternative treatments for children as well as systems for providing services. This review describes outcome instruments that can be used for clinical, health services and cost-effectiveness applications. There is a pressing need to identify the most appropriate instruments for measuring health-related quality-of-life outcomes in this population. Studies evaluating the cost-effectiveness of interventions or treatments for children with ASDs using the cost per quality-adjusted life year metric are lacking. Researchers have the potential to contribute greatly to the field of autism by quantifying outcomes that can inform optimal treatment strategies.

PedsQL gastrointestinal symptoms module item development: qualitative methods

OBJECTIVES

The objective of the present qualitative study was to develop the items and support the content validity for the Pediatric Quality of Life Inventory (PedsQL) Gastrointestinal Symptoms Module for pediatric patients with functional gastrointestinal (GI) disorders and organic GI diseases, hereafter referred to as GI disorders.

METHODS

The iterative process included multiphase qualitative methods. A literature review of GI disorders was conducted to generate domains for the focus interviews. Six pediatric gastroenterologists with extensive clinical experience in GI disorders provided expert opinion regarding the conceptual framework. A total of 98 participants, 46 pediatric patients ages 5 to 18, and 52 parents of patients ages 2 to 18 with physician-diagnosed GI disorders (chronic constipation, functional abdominal pain, irritable bowel syndrome, inflammatory bowel disease [Crohn disease, ulcerative colitis], gastroesophageal reflux disease), participated in the focus interviews and cognitive interviewing phases, including think-aloud and cognitive debriefing protocols.

RESULTS

Eleven domains were derived from the qualitative methods involving patient and parent interviews and expert opinion, with content saturation achieved, resulting in 76 items. The 11 domains consisted of items measuring stomach pain, stomach upset, food and drink limits, trouble swallowing, heartburn and reflux, gas and bloating, constipation, diarrhea, worry, medicines, and communication.

CONCLUSIONS

Qualitative methods involving pediatric patients and their parents in the item generation process support the content validity for the new PedsQL Gastrointestinal Symptoms Module. The PedsQL Gastrointestinal Symptoms Module is undergoing national multisite field testing as the next iterative phase.

Quality of life of adolescents with autism spectrum disorders: comparison to adolescents with diabetes

Relationships are of great importance during adolescence. Because of their social, communication and behavioral impairments, adolescents with Asperger's syndrome (AS) or high functioning autism (HFA) probably suffer from considerable impairment of their quality of life when facing their peers in school. Nevertheless, only one recent study has been published on this subject, indicating a lower health-related quality of life in children and adolescents with autism spectrum disorders (ASD) than in healthy controls. The goals of our study were to clarify the consequences of autistic disorder without mental retardation on such adolescents' daily lives, and to consider them in comparison with the impact of a chronic somatic disease (diabetes) and with the period of adolescence itself, using the VSP-A questionnaire. Adolescents with diabetes were chosen as a comparison group because of the encumbrance of having a constant need for insulin supplementation, to be assimilated to the constant need for communicative adjustments in teenagers with ASD, and the consequences in daily life. The effects of social skill training and social support on quality of life and the appropriateness of using the VSP-A in this population were also studied. Twenty-six adolescents with AS and HFA, 44 diabetic adolescents, and 250 controls completed a self-administered and validated questionnaire on quality of life, the VSP-A. Scores for adolescents with ASD were significantly lower than those of the control and the diabetic adolescents, especially for friendships, leisure time, and affective and sexual relationships. On the other hand, better scores were obtained for the relationships with parents and teachers and for self-image. Social parameters affected the quality of life of subjects with ASD, such as having friends, regularly participating in a sport, and having the support of a school carer. For subjects with autistic spectrum disorders and without mental retardation, impairment of quality of life is significant in adolescence and young adulthood. Such adolescents are dissatisfied with their relationships, although they often have real motivation to succeed with them. Relevance of VSP-A questionnaire in these special individuals is discussed.

Health-related quality of life in children and adolescents with autism spectrum disorder

OBJECTIVE

This study evaluates self- and proxy-reported health-related quality of life (HRQOL) in children and adolescents with autism spectrum disorders (ASD). The study also compares HRQOL in ASD patients with a healthy control sample and a psychiatric reference sample.

METHOD

42 children and adolescents (39 male, mean age: 12.7 ± 2.6 years, mean IQ: 100.5 ± 20.7) with the diagnosis of autism spectrum disorder (ASD) and their parents completed the Inventory for the Assessment of Quality of Life in Children and Adolescents (ILK).

RESULTS

Mean ILK LQ 0-28 scores were 20.6 (± 4.6) (self-report version) and 18.2 (± 4.0) (proxy version). Compared to a reference sample, mean ILK scores from the ASD sample were at the 47th percentile (self-report) and the 33rd percentile (proxy). Compared to children and adolescents with psychiatric disorders, self-reported ILK scores correlated with the 69th percentile, and proxy-reported ILK scores correlated with the 67th percentile. Self-reported HRQOL was significantly higher than proxy-reported HRQOL. No significant correlation was found between HRQOL and age, IQ, or autistic symptoms.

CONCLUSIONS

HRQOL in children and adolescents with ASD seems to be better than in other psychiatric disorders, but lower than in healthy controls.

PedsQL™ Cognitive Functioning Scale in pediatric liver transplant recipients: feasibility, reliability, and validity

OBJECTIVE

The PedsQL™ (Pediatric Quality of Life Inventory™) is a modular instrument designed to measure health-related quality of life and disease-specific symptoms. The PedsQL™ Cognitive Functioning Scale was developed as a brief generic symptom-specific instrument to measure cognitive functioning. The objective of the present study was to determine the feasibility, reliability, and validity of the PedsQL™ Cognitive Functioning Scale in pediatric liver transplant recipients.

METHODS

The 6-item PedsQL™ Cognitive Functioning Scale and the PedsQL™ 4.0 Generic Core Scales were completed by pediatric liver transplant recipients ages 8-18 years (n = 215) and parents of pediatric liver transplant recipients ages 2-18 years (n = 502). Both patient self-report and parent proxy-report were available for 212 cases. The 72-item Behavior Rating Inventory of Executive Function (BRIEF), a widely validated measure of executive functioning, was completed by 100 parents and 56 teachers on a subset of patients.

RESULTS

The PedsQL™ Cognitive Functioning Scale demonstrated minimal missing responses (0.0%, child report, 0.67%, parent report), achieved excellent reliability (α = 0.88 child report, 0.94 parent report), distinguished between pediatric patients with liver transplants and healthy children supporting discriminant validity, and was significantly correlated with the PedsQL™ 4.0 Generic Core Scales and the BRIEF supporting construct and concurrent validity, respectively. Pediatric liver transplants recipients experienced cognitive functioning comparable to long-term pediatric cancer survivors.

CONCLUSIONS

The results demonstrate the feasibility, reliability, discriminant, construct, and concurrent validity of the PedsQL™ Cognitive Functioning Scale in pediatric liver transplant recipients.
