Health-related quality of life (HRQoL) information from children facing rare and/or life-threatening disease serves important clinical functions. Longitudinal HRQoL ratings from 222 child-parent dyads collected at four time points during the first 16 weeks of cancer treatment are presented. Patient and parent HRQoL reports at the domain level, based on the Pediatric Quality of Life Inventory™ 4.0 Generic Core Scales, were compared over time, and variation in child/parent agreement by age, treatment intensity, and time on treatment was explored.
Analyses included consideration of missingness, differences between child and parent group mean domain scores averaged over assessments, agreement between individual child and parent, compared to group averages, and within-subject changes between assessments.
Children consistently reported higher functioning than their parents with differences varying by child age and HRQoL domain and diminishing over time. No differences were found by intensity of treatment. The between-subject correlation ranged from 0.61 (social functioning) to 0.86 (physical functioning) across time. Agreement within groups, defined by age, treatment intensity, and time were generally similar.
Results indicate moderate-to-good child/parent agreement with variability by domain of HRQoL. Findings underscore the complexity of self- and proxy-based report and support the use of information from both raters.
"Information variance could occur when the parent and child receive different information about clinical events, while criterion variance could occur when they weigh and respond to available information differently. These rater differences illustrate the importance of collecting pediatric HRQL data from both the parent and the child . In addition, we found that fathers rated their adolescent child’s global HRQL higher than mothers. "
[Show abstract][Hide abstract] ABSTRACT: Background
Pediatric health-related quality of life (HRQL) measures explore multiple domains of HRQL. To ease administration, burden, and implementation, we created a 7-item unidimensional global HRQL scale for children. This paper evaluates the psychometric properties of the global HRQL scale in children undergoing hematopoietic stem cell transplant (HSCT) and describes the trajectory of global HRQL scores over the 12-month course following HSCT.
As part of two longitudinal HSCT studies, HRQL was collected on 312 parent–child dyads using the Child Health Ratings Inventories. Parents of children aged 5–18 completed the pediatric global HRQL scale about their child and 117 adolescents completed the scale themselves. Psychometric properties were compared across both raters. Two repeated measures models were built to describe trajectories of (1) global HRQL for all children based on parent proxy report and (2) global HRQL for adolescents based on adolescent self-report and parent proxy report.
Internal consistency reliability was high for parent proxy report and adolescent self-report (Cronbach’s alpha 0.9, 0.8, respectively). Unidimensionality was verified using principal components analysis. Both models indicated decreased global HRQL in the presence of early complications related to HSCT and Model 1 further indicated decreased HRQL in the presence of later complications. Model 2 showed that parent proxies reported lower global HRQL scores than adolescent self-report.
This study has demonstrated the unidimensionality and strong psychometric properties of a 7-item global HRQL scale in a sample of children undergoing HSCT. Despite its brevity, scale scores vary in clinically meaningful ways. Future applications of this scale are encouraged.

[Show abstract][Hide abstract] ABSTRACT: Little is known regarding the health-related quality of life (HRQL) trajectory of children with sickle cell disease or thalassemia ("hemoglobinopathies") following hematopoietic stem cell transplantation (HSCT).
We serially evaluated the HRQL of 13 children with hemoglobinopathies who received HSCT during two prospective multi-center studies using the Child Health Ratings Inventories (CHRIs). The HRQL scores among children with hemoglobinopathies, as reported separately by the children and their parents were compared using repeated measures models to scores of a comparison group of children receiving HSCT for malignancies or severe aplastic anemia.
The sample included 13 children with hemoglobinopathies (median age: 8 years, range 5-18) and 268 children in the comparison group (median age: 11 years, range 5-18). There were similar rates of early infection, chronic graft versus host disease, and all-cause mortality between the two groups. There was no significant difference in recovery to baseline scores for physical, emotional, and role functioning by 3 months for either group. Children with hemoglobinopathies had higher HRQL scores for physical (beta = 12, se = 5.5, P = 0.01) and baseline emotional functioning (beta = 11.6, se = 5.5, P = 0.03) than the comparison group. For all domains for both groups, parent reports demonstrated a nadir at 45 days with recovery to baseline by 3 months following transplant. Children's ratings were higher than those of their parents in both diagnostic groups.
Children with hemoglobinopathies had higher physical and emotional functioning scores prior to HSCT and experienced a similar pattern of recovery to their baseline functioning by 3 months post-HSCT when compared to children receiving HSCT for acquired conditions.
[Show abstract][Hide abstract] ABSTRACT: With the improved survival of childhood acute lymphoblastic leukemia (ALL), the effect of treatment on psychosocial well-being becomes increasingly relevant. Literature on sleep and fatigue during treatment is emerging. However, information on these subjects after treatment is sparse. This cross-sectional study examined sleep and fatigue in relation to depression and quality of life (QoL) after treatment for childhood ALL.
Sleep, fatigue, depression, and QoL were evaluated by parent proxy and/or child self-reports of the Children's Sleep Habits Questionnaire, the PedsQL™ multidimensional fatigue scale, the Children's Depression Inventory and the Child Health Questionnaire. All total scores were compared to Dutch norm references.
Sixty-two children were included, being 36 (interquartile range 22–62) months after finishing treatment. Parents rated the ALL survivors as having more disturbed sleep, more fatigue and poorer physical QoL compared to the Dutch norm. ALL survivors themselves reported less sleep problems, less depressive symptoms, and better psychosocial QoL than the Dutch norm. More sleep disturbances and fatigue correlated with more symptoms of depression and a worse QoL.
Differences in parental and self-reports, including worse parental ratings, might be explained by worried parents and/or the adaptive style of the children. Impaired sleep and fatigue correlated with more depressive symptoms and a worse QoL. Pediatr Blood Cancer 2013; 60: 479–485.
