Validation of the Chinese version of the Pediatric Quality of Life Inventory (PedsQL) Cancer Module

Validation of the Chinese version of PedsQL™ brain tumor module

Background

The study introduced the Pediatric Quality of Life Inventory™ (PedsQL™) brain tumor module for the first time in China. Further, the Chinese version of the PedsQL™ brain tumor module was developed and its feasibility, reliability, and validity were investigated.

Methods

A total 129 cases completed the assessment. Feasibility was evaluated according to the percentage of missing items and the time required to complete the questionnaire. Internal consistency, retest reliability, and split-half reliability were tested to confirm reliability. We evaluated validity by testing content validity, construct validity, and criterion-related validity. The consistency between the child-self and parent-proxy reports was analyzed by calculating the correlation coefficient (r value) between them.

Results

The Cronbach's alpha values for all subscales were above 0.7 and many subscales scored more than 0.9. The intra-class correlation coefficients of retest reliability were higher than 0.9. The split-half reliability scores for all subscales were higher than 0.6. The factor-item correlations ranged between 0.575-0.922 in the child report and 0.492-0.949 in the parent report. Exploratory factor analyses produced five factors corresponding to each subscale in the child report and six factors in the parent report.

Conclusion

The feasibility, reliability, and validity of the Chinese PedsQL™ brain tumor module were ascertained through this study. This module can be used to effectively monitor children with brain tumors and conduct descriptive or exploratory studies to determine the risk factors affecting their quality of life. This would help develop a new basis for formulating measures to improve patient prognosis and quality of life.

A critical evaluation of the content validity of patient-reported outcome measures assessing health-related quality of life in children with cancer: a systematic review

BACKGROUND

With increasing survival rates in pediatric oncology, the need to monitor health-related quality of life (HRQOL) is becoming even more important. However, available patient-reported outcome measures (PROMs) have been criticized. This review aims to systematically evaluate the content validity of PROMs for HRQOL in children with cancer.

METHODS

In December 2021, a systematic literature search was conducted in PubMed. PROMs were included if they were used to assess HRQOL in children with cancer and had a lower age-limit between 8 and 12 years and an upper age-limit below 21 years. The COSMIN methodology for assessing the content validity of PROMs was applied to grade evidence for relevance, comprehensiveness, and comprehensibility based on quality ratings of development studies (i.e., studies related to concept elicitation and cognitive interviews for newly developed questionnaires) and content validity studies (i.e., qualitative studies in new samples to evaluate the content validity of existing questionnaires).

RESULTS

Twelve PROMs were included. Due to insufficient patient involvement and/or poor reporting, the quality of most development studies was rated 'doubtful' or 'inadequate'. Few content validity studies were available, and these were mostly 'inadequate'. Following the COSMIN methodology, evidence for content validity was 'low' or 'very low' for almost all PROMs. Only the PROMIS Pediatric Profile had 'moderate' evidence. In general, the results indicated that the PROMs covered relevant issues, while results for comprehensiveness and comprehensibility were partly inconsistent or insufficient.

DISCUSSION

Following the COSMIN methodology, there is scarce evidence for the content validity of available PROMs for HRQOL in children with cancer. Most instruments were developed before the publication of milestone guidelines and therefore were not able to fulfill all requirements. Efforts are needed to catch up with methodological progress made during the last decade. Further research should adhere to recent guidelines to develop new instruments and to strengthen the evidence for existing PROMs.

Associating sleep quality, quality of life and child poly-victimization

BACKGROUND

The role of sleep deprivation in the relationship between child poly-victimization and pediatric quality of life (PedsQL) has received little attention.

OBJECTIVE

This study aims to provide a profile of the association between child victimization and poly-victimization and PedsQL among children, examining the role of sleep quality patterns in these relationships.

PARTICIPANTS AND SETTING

We conducted a cross-sectional school survey study of family structure and child victimization among families in Hong Kong in 2016-17 with two-stage stratified sampling. The final sample consisted of 5, 567 students recruited from a representative sample of 107 kindergartens, primary schools, and secondary schools in all districts of Hong Kong.

METHODS

Multi-phase regression analysis and simple slope analysis were conducted to examine the moderating effects of sleep quality between child victimization and PedsQL.

RESULTS

The findings showed that children who experienced four or more types of victimization were more likely to show parasomnia and daytime dysfunction symptoms than those experiencing one to three types of victimization and non-victims. It also revealed significant relationships between child poly-victimization and lower levels of PedsQL, which were moderated by parasomnia and daytime dysfunction.

CONCLUSIONS

This study has implications for clinicians in targeting the pattern of sleep changes combined with holistic screening in outpatient services for early detection of child poly-victims.

Cross-Cultural Validation of Health and Quality of Life Measures for Children in Hong Kong

Objective

The Pediatric Quality of Life Inventory (PedsQL™) 4.0 is a health-related quality of life (HRQOL) measure designed for clinical practice and research, health policy evaluation, and general population surveys. There is a dearth of instruments measuring quality of life in children which are available in Chinese and validated for Chinese populations. Therefore, this study attempted to establish the Hong Kong populations' norms for the Chinese version of PedsQL™ and examined the psychometric properties of the measure for this population.

Methods

Sixty-nine children (aged 7 to 12 years) and their parents completed the child self-report and the parent proxy report, respectively, of the PedsQL™ 4.0 Generic Module. To evaluate construct validity, a group comparison of children with special educational needs (SEN) (n = 21) and those with typical development (TD) (n = 48) was conducted. Differences based on age group and gender and parent–child agreement on the perception of the child's HRQOL were also examined.

Results

Children with SEN had a lower quality of life perception than those with TD in the physical, social, and schooling domains. No significant differences in emotional health were found between the two groups. The differences between the children with SEN and with TD varied based on age group and gender. The differences between the parents' and children's perceptions of the children's HRQOL were insignificant in this sample.

Conclusion

Norms for the Chinese version of the PedsQL™ 4.0 Generic Module for the Hong Kong population were established in the study, and both the child self-report and parent proxy report were found to be reliable and valid for this population.

The Reliability of the Thai version of Health-Related Quality of Life Questionnaire: PedsQL 3.0 Cancer Module

Assessing the health-related quality of life (HRQOL) is highly recommended as a standard of care for children with cancer in conjunction with medical treatment. The Pediatric Quality of Life Inventory (PedsQL) Cancer Module is a standard tool designed to assess the HRQOL among pediatric oncology patients. This study aimed to evaluate the reliability and correlation of the PedsQL 3.0 Cancer Module in Thai version between child and parent reports. A cross-sectional study was conducted on 85 Thai children with cancer and their families. Excellent internal consistency of the PedsQL 3.0 Cancer Module of the Thai version was addressed among child and parent reports (0.92 and 0.94, respectively). Overall positive correlations were also found between child and parent reports ( r = 0.61, P < .001). However, the statistically significant differences of HRQOL scores between child and parent reports were determined on procedural anxiety (70.05 ± 26.67 vs 60.03 ± 25.6, P = .003), treatment anxiety (88.15 ± 17.37 vs 76.82 ± 26.7, P = .001), worry (66.67 ± 25.59 vs 55.34 ± 30.37, P = .003) and the total score (74.37 ± 15.7 vs 70.42 ± 17.15, P = .034). This study demonstrated desirable internal reliability with positive correlations between child and parent reports of the PedsQL 3.0 Cancer Module in Thai version, although possible differences between child and parent HRQOL scores should be considered.

Evaluation of Patient-Reported Outcome Measures of Positive Psychosocial Constructs in Children and Adolescent/Young Adults with Cancer: A Systematic Review of Measurement Properties

Introduction: Children, adolescents, and young adults with cancer are a vulnerable population in whom improvements in psycho-oncology care would be valuable. We previously published a scoping review exploring what is known about positive psychological constructs in this population. A key finding was that evidence-based patient-reported outcome measures (PROMs) were needed to standardize psycho-oncology research. Methods: We undertook a systematic review of measurement properties focused on PROMs in the pediatric and adolescent/young adults (AYAs) with cancer populations. We searched for PROMs that measured at least 1 of 15 previously identified, key positive constructs. This systematic review followed COSMIN guidelines, considered the gold standard manual for systematic reviews of measurement properties. Results: We identified 20 (22 if proxy reports are counted separately) unique PROMs that met inclusion criteria. Of those, only five were recommended for use given the current evidence. The remainder may be used if no alternative exists. Only eight PROMs had any evidence of content validity, considered the most important psychometric property by COSMIN. Many studies were at risk of bias owing to incomplete or suboptimal methods. Discussion: Five PROMs are considered reliable for the pediatric and AYA with cancer populations. A number of PROMs require additional research to ensure their items and instructions are comprehensive, relevant, and comprehensible to children and AYAs. Given the overall lack of research, this review may be considered a starting point for the future refinement of a core set of PROMs to measure positive psychological constructs.

Problems, Stressors and Needs of Children and Adolescents with Cancer

BACKGROUND

Cancer diseases in children and adolescents are considered to be one of the most serious health problems in the world. It is estimated that about 151,435 cases are diagnosed in children annually. Children with cancer experience many comorbid symptoms related to diagnosis and treatment that can profoundly affect their lives. They experience physical and emotional suffering, which affects their well-being and physical fitness, influencing the prognosis and deteriorating their physical, mental and social functioning. Given the limited data, an attempt was made to assess the problems of the biopsychosocial sphere of need and stressors among children and adolescents treated for cancer. Accurate symptom assessment is essential to ensure high-quality care and effective treatment.

PATIENTS AND METHODS

The qualitative study was conducted in pediatric oncology of hospitals in Poland. Children diagnosed with cancer were invited to participate in the study to assess their problems, stressors and needs.

RESULTS

The study included 520 people, where female sex constituted 48% and male 52%. The mean age of the children is 13.2 SD = 2.5. Negative experiences related to the disease are experienced by 82% of children. Among the surveyed children, the most experienced were anxiety (61%). The conducted research shows that as many as 69% of all respondents experienced states that indicate severe depression. The most common somatic problems reported by children were pain (58%). The most dominant areas of life that had a negative impact was body image (85%).

CONCLUSIONS

Children and adolescents diagnosed with neoplastic disease experience many problems and stressors in every sphere of life, which undoubtedly affects a high level of unmet needs. The main category of needs concerning the challenges faced by children with cancer was psychological and care problems. In the youth group, the needs were mainly related to education and social support.

Modifiable Factors for the Trajectory of Health-Related Quality of Life among Youth Growing Up in Poverty: A Prospective Cohort Study

Poverty is a decisive risk factor for poor health and well-being, and its negative consequences could be more severe and substantial among children. Understanding the factors associated with improvement in well-being is vital to design interventions. This is a prospective cohort study of 546 youth growing up in families in poverty in Hong Kong. All participants were assessed twice, in 2016 and 2019, in regard to their physical and mental health, as well as for different economic, social, and psychological variables. The results show that approximately 41% experienced an improvement in their health-related quality of life (HRQoL). Findings from the logistic regression analyses suggest that the health and development of youth in poverty may be restored by promoting social support, a sense of hope, future orientation, job stability, and money management practices, such as savings, during childhood and adolescence. The findings shed light on future policy making and forms of service development that could help to end the vicious cycle of poverty and hampered health.

Validity and reliability of the Italian version of the cardiac quality of life questionnaire for pediatric patients with heart disease (PedsQLTM)

Background

Congenital heart disease (CHD) accounts for nearly a third of all major congenital anomalies. Advances in pediatric cardiology shifted attention from mortality to morbidity and health-related quality of life (HRQOL) of patients with CHD and impact on their families. The purposes of this study were to assess the validity and reliability of the Italian version of the Pediatric Quality of Life (PedsQL) Cardiac Module and to create normative data for the Italian population.

Methods

This was an observational cross-sectional study of pediatric patients (aged 2–18 years) with congenital or acquired Heart Disease (HD) and their parents. Families were asked to complete the cardiac pediatric health-related quality of life questionnaire (the Italian PedsQL™ 3.0 Cardiac Module) and the generic pediatric health-related quality of life questionnaire (PedsQL™ 4.0 Generic Core Scales). The sequential validation procedure of the original United States version of the PedsQL™ 3.0 Cardiac Module was carried out under the instruction of the MAPI Research Institute.

To assess construct validity, Pearson’s correlation coefficients were assessed between scores on the Cardiac Module scales and scores on the scales of the General Module. To determine agreement between patient self-report and parent proxy-report, we used intraclass correlation coefficients (ICCs). To evaluate Internal consistency of items, we used Cronbach’s alpha Coefficient.

Results

The study enrolled 400 patients. Construct validity is good between PedsQL Cardiac Module total scores and PedsQL total scores (p < 0.001). The recommended standard value of 0.7 was reached on the Cardiac and General Module core scales. Intercorrelations between PedsQL Cardiac module and PedsQL scores revealed medium to large correlations. In general, correlations between Patient self-reports are poorer than Parent-proxy ones.

Conclusions

Cardiac PedsQL scores are valid and reliable for pediatric patients with congenital and acquired HD and may be useful for future research and clinical management.

Associations Between Child Maltreatment and Adolescents' Health-Related Quality of Life and Emotional and Social Problems in Low-Income Families, and the Moderating Role of Social Support

This study aimed to examine the associations between different types of child maltreatment and health-related quality of life (HRQoL) and emotional and social problems in adolescents, and to examine the moderating effect of social support on those associations. A cross-sectional survey was conducted between January and June 2016 in Hong Kong. The sample comprised 351 parent and adolescent dyads from low-income families. The parents reported on child maltreatment (physical abuse, psychological aggression, and neglect), and the adolescents reported on their HRQoL, emotional problems, and social problems. The adolescents' perceived social support was included as a potential moderator. Results of the study show that child physical abuse was strongly associated with emotional and social problems (B = 0.91-1.45, p < .05). Lower overall HRQoL was associated with psychological aggression (B = -3.96, p < .05) and neglect (B = -4.14, p < .05). Physical functioning was affected by psychological aggression (B = -3.16, p < .05), and emotional functioning was affected by neglect (B = -4.82, p < .05). Social functioning was impacted by all three types of maltreatment (B = -9.16 to -5.26, p < .05). This study extends previous literature by showing the varying effects of different types of child maltreatment on children's health in the context of low-income families. The findings of this study also support that peer social support may buffer the effects of child physical abuse on adolescents' emotional and social problems.

Quality of life in paediatric solid tumours: a randomised study of metronomic chemotherapy versus placebo

OBJECTIVE

Health-related quality of life (HRQoL) is an important outcome for paediatric cancer studies. We compared the HRQoL between patients of progressive paediatric solid tumours randomised to metronomic chemotherapy versus placebo.

METHODS

In this double-blinded, placebo-controlled randomised study of 108 children with progressive malignancies, HRQoL was evaluated using the PedsQOL Cancer module V.3 at baseline (A1), A2 (9 weeks or earlier if progressed) or A3 (18 weeks or earlier if progressed).

RESULTS

There was no statistically significant difference in the change in quality of life produced by each arm from A1 to A2 in either mean total scores or individual domain scores, reported by children or their parents. On analysing the response according to the minimal clinically important difference, defined as an improvement by 4.5 points, we found no significant differences, be it among bone-sarcomas, other tumours, responders (those who received ≥9 weeks of treatment) or non-responders.

CONCLUSIONS

The present study concludes that there was no significant difference in HRQoL, between the patients in the two arms at second and later assessments. This is consistent with the other survival endpoints in the study.

A Child Development Fund Program, Emotional Development, and Poverty Reduction

OBJECTIVES

We aim to examine the effects of the Child Development Fund (CDF) program on the long-term psychological, health, social, and financial development of children in poverty.

METHODS

The current study was a 4-year follow-up survey study (the follow-up study) of a nonrandomized controlled trial (the first study), conducted in 2019 and 2015, respectively, in Hong Kong. Subjects were 902 young adults who were from families living in poverty and receiving financial assistance from the government and who had completed the first study. Approximately 61% of the subjects (N = 546) completed the current follow-up study.

RESULTS

Of the 546 subjects (46% male), 335 (61%; CDF participants) completed the CDF program between 2011 and 2015, and 211 (39%; CDF nonparticipants) were matched controls in the first study. The mean age was 20.64 years (SD = 2.72). After adjustments of covariates, the CDF participants reported fewer behavioral problems, higher levels of study motivation, higher levels of hope, and more positive attitudes toward their future education. The CDF participants also perceived greater social support from significant others and reported greater amounts of money saved every month. After further adjustments, CDF participants showed greater improvements in health-related quality of life related to emotional functioning. A considerable number of families of the CDF participants who were working for a living were no longer reliant on financial assistance from the government.

CONCLUSIONS

The positive effects of the CDF program on children in poverty could be sustained throughout adolescence to young adulthood. Findings warrant the promotion of the program to reach more children.

The reliability of the health related quality of life questionnaire PedsQL 3.0 cancer module in a sample of Swedish children

Background

The Pediatric Quality of Life Inventory (PedsQL) is a modular instrument, designed to integrate generic and disease specific measures, and includes both self- and proxy-reports. The aim of the study was to assess the reliability and limited validity of the Swedish version of the disease specific Pediatric Quality of Life Inventory 3.0 Cancer Module Scales (PedsQL 3.0), in a sample of Swedish children diagnosed with cancer.

Method

A total of 94 families at The Queen Silvia Children’s Hospital, Sahlgrenska University participated in the study. The Pediatric Quality of Life Inventory 4.0 Generic Core Scales (PedsQL 4.0) and the PedsQL 3.0 were administered to 63 children (aged 5–18 years) with cancer and to 94 parents of children with cancer aged 2–18 years.

Results

The internal consistency of the PedsQL 3.0, reached or exceeded Cronbach’s alpha values of 0.70 for both -self- and proxy-reports. The PedsQL 4.0 and PedsQL 3.0 were highly correlated (r = 0.94 for proxy-reports and r = 0.91 for self-reports), indicating convergent validity.

Conclusion

PedsQL 3.0 Cancer Module Scales can be used as a valuable tool for measuring cancer-specific HRQOL in child populations, both in research and in clinical practice.

Symptom Experience of Children With Cancer Younger Than Eight Years of Age: An Integrative Review

CONTEXT

Children with cancer endure multiple symptoms during treatment. However, there remains a lack of systematic approaches to capture the whole picture of the symptom experience of children with cancer younger than eight years of age.

OBJECTIVE

The purpose of this study was to conduct an integrative review to explore symptom experience of children with cancer younger than eight years of age.

METHODS

A literature search of PubMed, CINAHL, Web of Science, PsycINFO, Cochrane databases, and four Chinese databases was performed to identify empirical studies, followed by an evaluation of empirical quality and data extraction and synthesis.

RESULTS

Twelve articles covering 11 symptoms met the inclusion criteria. Children with cancer under the age of eight years experienced multiple intense symptoms, especially pain, worry, and anxiety. PedsQL™ Cancer Module (for age five to seven years) was the most commonly used instruments. There were limited data on these children's symptom quality, timing, and distress. Discordance between a child's age and symptom intensity was noted. Inconsistent concordance existed between children and their proxy symptom reports.

CONCLUSION

Children with cancer younger than eight years of age experience multiple symptoms. There is a need to investigate the full symptom profiles of these young children in consideration of their developmental nuances; to examine the concordance among different symptom reporters; and to conduct more qualitative studies to explore their symptom experience.

Disability-Specific Associations with Child Health and Functioning

This study examined the health profile of children with different types of disabilities and explored the disability-specific associations with various types of health and functioning using a large nonclinical sample of children. A cross-sectional school survey was conducted during 2016 and 2017. A total of 4114 children (aged 6⁻18 years) receiving primary or secondary education, or their proxy, in Hong Kong participated in the study. Disabilities were categorized as (a) physical disabilities; (b) learning and developmental disabilities; (c) intellectual disabilities; (d) internalizing disorders or mental illness; and (e) autism spectrum disorder. Health-related quality of life (QoL), sleep-related QoL, activities of daily living (ADL), emotional functioning, and social functioning were assessed and compared between children with disabilities and those without. The results showed that children with disabilities showed poorer physical functioning, health-related QoL, and emotional and social functioning than their counterparts without disabilities. Disability-specific associations with health were found: (a) physical disabilities and intellectual disabilities were associated with greater difficulties in ADL; (b) language impairment and Attention deficit/ hyperactivity disorder (ADHD) were negatively associated with sleep-related QoL; (c) all types of disabilities but hearing impairment were negatively associated with health-related QoL (HRQoL); and (d) language impairment, ADHD, internalizing disorder, as well as autism spectrum disorder were associated with greater abnormal behavioral difficulties. The findings warrant the development of tailor-made intervention programs and give insights to effective resource allocation for the children in need.

Effect of Generational Status on Child Well-Being: Mediating Effects of Social Support and Residential Instability

Children in migrant families often encounter difficulties that have great impacts on their health. However, there is a lack of research to examine generational status and child health-related quality of life (HRQoL). This study compared the HRQoL of children, aged 3 to 19 years, born in Hong Kong to mainland parents with second- and third-or-higher-generation children; and explores the mediating effects of residential instability and of social support on the association between generational status and HRQoL. A sample comprised 4807 reports on children (mean age = 7.47 years) in Hong Kong was analyzed. Significantly lower HRQoL related to physical functioning was observed among children in migrant families. Association between generational status and child HRQoL was mediated by commute time between home and school, frequency of moving home, and social support. Findings lend utility to addressing similar issues amongst other developmental immigrant populations.

The Longer-Term Psychosocial Development of Adolescents: Child Development Accounts and the Role of Mentoring

Objective: To examine the long-term development of adolescents who participated in the Child Development Fund (CDF), which was a community intervention that consisted of Child Development Accounts (CDAs) and mentorship components. Design: This was an evaluative study of the CDF community intervention and was conducted between January and June 2016 in Hong Kong. Participants: A total of 902 adolescents from low socioeconomic backgrounds participated in this study (552 in the CDF and 350 in the comparison group). All CDF participants completed the 3-year CDF program between 2011 and 2015. Main outcome measures: We assessed different developmental aspects of the adolescents, including health in terms of health-related quality of life; behavioral problems; attitude in terms of hope; cognitive capacity in terms of schooling; and social aspects in terms of social support. Results: Compared to the non-participants, the CDF participants appeared to have fewer behavioral problems, higher levels of perceived social support, higher levels of hope, better understanding of academic subjects, higher levels of motivation to study, fewer school withdrawal behaviors, and better quality of life related to social functioning. The male gender moderated the program's effect on hope. Results also show that higher levels of mentorship quality moderated the program's effect on social support, hope, self-perceived understanding of academic subjects, and motivation to study. Conclusion: Adolescents who participated in the CDF program appeared to perform better than the non-participants in regard to behavioral, academic, attitudinal, and social aspects. Good quality of mentorship had a positive influence on the program's effects. The CDF appears to be a promising program offering long-term and multi-dimensional benefits to participants.

Quality of life after living donor liver transplant for biliary atresia in Japan

BACKGROUND

Health-related quality of life (HRQOL) is an important outcome in solid organ transplantation. This study evaluated and explored the factors of generic and transplant-specific HRQOL in Japanese pediatric and adolescent patients with biliary atresia (BA) after living donor liver transplant (LDLT).

METHODS

A cross-sectional survey using anonymous questionnaires was completed between April and July 2015. Patient medical records were accessed. The Japanese version of Pediatric Quality of Life Inventory^TM Generic Core Scales and Transplant Modules (child self-report and parent proxy-report) was administered.

RESULTS

Participants consisted of 75 patients (mean age at survey, 9.6 years) and 74 parents. Japanese patients reported higher generic and transplant-specific HRQOL (total score) than that reported by US patients with BA after LT (US I; age at survey, 7.2 years) and by US patients after solid organ transplant (US II; age at survey, 11.3 years; LT, 53.8%; effect size, 0.55-0.96). Japanese parents, however, rated their children's generic HRQOL (total score) similar to that rated by the US I and II parents (0.13 and 0.30, respectively) and reported lower transplant-specific HRQOL (total score) than that reported by US II (0.26). Although the number of types of prescribed drugs was a common factor in HRQOL, most demographic and medical factors (e.g. child's age at survey and consultation frequency) varied with reporter (i.e. patients and parents).

CONCLUSIONS

The levels and factors of generic and transplant-specific HRQOL of Japanese pediatric and adolescent patients with BA after LDLT varied with reporter (i.e. patients or parents).

Can family structure and social support reduce the impact of child victimization on health-related quality of life?

This study aims at providing a profile of the association between different types of child victimization and polyvictimization and health-related quality of life (HRQoL) among school-aged children, and examining the impact of family structure and social support on the negative health consequences associated with violent victimization. We conducted a cross-sectional school survey in Hong Kong using a two-stage stratified sampling procedure. The final sample comprised 4139 children's self-reports and proxy-reports (boys=51.5%; mean age=6.3). The main outcome was HRQoL measured with the Pediatric Quality of Life Inventory (PedsQL). Family structure was represented by parents' marital status, major caregivers, number of siblings and the living arrangement of children. Child victimization, social support, and demographic characteristics were also measured. All types of child victimization were associated with compromised HRQoL, and the strength of association varied across different types of child victimization. Family structure (in particular the number of siblings and whether additional childcare was received from grandparents) and social support were associated with better HRQoL. The negative associations between child victimization and polyvictimization and HRQoL were reduced when there was an adjustment made for family structure and social support. Findings show that family structure and social support are related to a reduction in negative health consequences for child victimization. The varying strengths of negative associations between victimization and HRQoL highlight the possibility that the effects of child victimization on health might not be homogeneous.

Construct and Criterion Validity of the PedsQL™ 4.0 Instrument (Pediatric Quality of Life Inventory) in Colombia

BACKGROUND

This study aimed at determining the validity of the Pediatric Quality of Life Inventory 4.0 (PedsQL™ 4.0) for the measurement of health-related quality of life (HRQOL) in Colombian children.

METHODS

Validation study of measurement instruments. The PedsQL™ 4.0 was applied by convenience sampling to 375 pairs of children and adolescents between the ages of 5 and 17 and to their parents-caregivers, as well as to 125 parents-caregivers of children between the ages of 2 and 4 in five cities of Colombia (Bogota, Medellin, Cali, Barranquilla and Bucaramanga). Construct validity was assessed through the use of exploratory and confirmatory factor analysis, and criterion validity was assessed by correlations between the PedsQL™ 4.0 and the KIDSCREEN-27.

RESULTS

The instrument was applied to 375 children (ages 5-18) and 125 parents of children between the ages of 2 and 4. Factor analysis revealed four factors considered suitable for the sample in both the child and parent reports, whereas Bartlett's test of sphericity showed inter-correlation between variables. Scale and subscales showed proper indicators of internal consistency. It is recommended not to include or review some of the items in the Colombian version of the scale.

CONCLUSIONS

The Spanish version for Colombia of the PedsQL™ 4.0 displays suitable indicators of criterion and construct validity, therefore becoming a valuable tool for measuring HRQOL in children in our country. Some modifications are recommended for the Colombian version of the scale.

Development of the Japanese version of the Pediatric Quality of Life Inventory™ Transplant Module

BACKGROUND

Health-related quality of life (HRQOL) is an important outcome in pediatric solid organ transplantation. Considering the emerging problems after transplantation, an evaluation of transplant-specific aspects of HRQOL is essential, but no validated HRQOL measure is available in Japan. The aim of this study was therefore to develop the Japanese version of the Pediatric Quality of Life Inventory^™ (PedsQL) Transplant Module Child Self-Report and to investigate its feasibility, reliability, and validity.

METHODS

Based on the PedsQL linguistic validation process, the Japanese version of the PedsQL Transplant Module was developed through translation and cognitive interviews (patient testing). The scale's reliability and validity were investigated, using statistical analyses of field tests of the target population.

RESULTS

Eighty-seven pairs of pediatric liver-transplant recipients and their parents participated in the field test. The pediatric patients completed the measure in 3-7 min, and the rate of missing items was low (0.27%). Excellent internal consistency and test-retest reliability were confirmed. Known-groups validity, concurrent validity, and convergent and discriminant validity also were confirmed.

CONCLUSIONS

Excellent feasibility, reliability, and validity of this Japanese self-report version of the PedsQL Transplant Module Child Self-Report were verified. As a measure of transplant-specific aspects of HRQOL in Japanese pediatric patients who have undergone organ transplants, the Japanese version of the PedsQL Transplant Module is appropriate for use in clinical and research settings.

Reliability and Validity of the Turkish Version of the PedsQL 3.0 Cancer Module for 2- to 7-Year-Old and the PedsQL 4.0 Generic Core Scales for 5- to 7-Year-Old: The Hacettepe University Experience

Objective:

The aim of this study was to investigate the reliability and validity of the Turkish version of the Pediatric Quality of Life Inventory (PedsQL) 3.0 Cancer Module for 2- to 7-year-old and the PedsQL 4.0 Generic Core Scales for 5- to 7-year-old in childhood cancer.

Materials and Methods:

The PedsQL 3.0 Cancer Module and PedsQL 4.0 Generic Core Scales were administered to children with cancer and their parents at Hacettepe University. Internal consistency was determined by using Cronbach’s alpha and test-retest reliability was determined by using the intraclass correlation coefficient (ICC). Construct validity was assessed by comparing the results of the PedsQL 3.0 Cancer Module with those of the PedsQL 4.0 Generic Core Scales.

Results:

Cronbach’s alpha of the PedsQL 3.0 Cancer Module varied from 0.803 to 0.873 and that of the PedsQL 4.0 Generic Core Scales from 0.665 to 0.841. Test-retest ICC values of the PedsQL 3.0 Cancer Module varied from 0.877 to 0.949 and those of the PedsQL 4.0 Generic Core Scales from 0.681 to 0.824. The correlation of the PedsQL 3.0 Cancer Module with subscale scores of the PedsQL 4.0 Generic Core Scales showed that there were excellent to fair correlations between the two scales. The relationship between parent proxy-report and child self-report of the PedsQL 3.0 Cancer Module had very good correlation (r=0.694, p<0.001), as did the PedsQL 4.0 Generic Core Scales (r=0.540, p=0.002).

Conclusion:

This study demonstrated the reliability, validity, and feasibility of the Turkish version of the PedsQL 3.0 Cancer Module in 2- to 4-year-old and 5- to 7-year-old and the PedsQL 4.0 Generic Core Scales in 5- to 7-year-old in childhood cancer.

Psychometric study of the European Portuguese version of the PedsQL 3.0 Cancer Module

BACKGROUND

Health-related quality of life (HRQoL) is an important outcome to assess the impact of cancer. This article examines the psychometric properties of the European Portuguese self-report version of the Pediatric Quality of Life Inventory™ Cancer Module (PedsQL™ 3.0 Cancer Module) in children and adolescents with cancer.

METHODS

The participants, 332 children/adolescents diagnosed with cancer (8-18 years old), completed measures to assess HRQoL (PedsQL™ 3.0 Cancer Module and DISABKIDS Chronic Generic Measure; DCGM-12) and anxiety (Revised Children's Manifest Anxiety Scale - second edition; RCMAS-2). A subsample (n = 52) completed the PedsQL™ 3.0 Cancer Module a second time following one-week. The pediatric oncologists completed the Intensity of Treatment Rating Scale 3.0 (ITR 3.0).

RESULTS

For the whole sample, the PedsQL™ 3.0 Cancer Module demonstrated good item discrimination (rs = .30 to .54). The confirmatory factor analysis testing the presence of eight first-order factors loading significantly in a second-order factor revealed an acceptable fit (CFI = .91; RMSEA = .05). The correlation of PedsQL™ 3.0 Cancer Module with DCGM-12 (rs = .17 to .58), and with RCMAS-2 (rs = -.16 to-.51) attested convergent validity. This inventory demonstrated minimally acceptable to very good internal consistency (αs = .65 to .87) and temporal stability (ICCs = .61 to .81).

CONCLUSIONS

These findings demonstrate that the European Portuguese self-report version of the PedsQL™ 3.0 Cancer Module is a valid and reliable instrument for assessing HRQoL in pediatric cancer.

Quality of life of children and adolescents with cancer: revision of studies literature that used the Pediatric Quality Of Life Inventory

OBJECTIVE

To assess the quality of life of children and adolescents with cancer of studies that applied the Pediatric Quality of Life Inventory 3.0 Cancer Module.

METHODOLOGY

The study was carried out on the basis of data Scopus Web of Science, BIREME, EBSCO host and Psychoinfo of articles in Spanish, English and Portuguese, and published from 1998 to 2013 that used the Pediatric Quality of life Inventory 3.0 Cancer Module.

RESULTS

21 articles were selected, of which 47.6% were carried out in America, and 61.9% of editions comprehended from 2011 to 2013. The scores variation by dimensions and in general was probably related for the selection of comparison groups, as the diversity of inclusion criteria and variants may be observed for the analysis in each study. The existence of a standard dimension could not be verified either for children ́s /adolescents reports or for parents.

CONCLUSION

It is concluded that the scores averages by dimensions in general have not achieved values below 30 and the largest scores by dimension are above 80. It is suggested that the treatment anxiety dimension in children ́s and adolescents ́s reports may have obtained the largest scores within each study, that is lesser than the difficulty of the children and adolescents in face of the treatment and cancer. Nursing becomes a constant presence in the life of children and adolescents with cancer and it may provide a better quality of life for developing nursing activities and the team may demistify, clarify and help in all phases of the illness and treatment.

Psychometric properties of the Chinese version of the Pediatric Quality Of Life Inventory 4.0 Generic Core scales among pediatric cancer patients

BACKGROUND

The Pediatric Quality of Life Inventory (PedsQL) 4.0 Generic Core Scales are commonly used to assess health-related quality of life of healthy children and pediatric patients. Validation of the Generic Core Scales among Chinese pediatric cancer patients has not been reported in the literature. The scales can serve to measure different quality-of-life domains that are not captured by the PedsQL Cancer Module.

OBJECTIVE

Psychometric properties of the Chinese version of the PedsQL 4.0 among pediatric cancer patients and their caretakers were examined.

METHODS

The Generic Core Scales were administered to 335 pairs of pediatric cancer patients (aged 8-18 years) and their caretakers in Hong Kong.

RESULTS

A 5-factor structure (physical, emotional, social, school-related cognitive function, and missed school) was identified in the patient and proxy versions of the scales using confirmatory factor analysis. Both versions of the total scale reported Cronbach α's of .90 or greater, with almost all subscales reporting α's of .70 or greater. Test-retest reliability at 2 weeks was acceptable (intraclass correlations ≥0.60) for a majority of subscales. Agreement between patients' and caretakers' ratings was medium.

CONCLUSIONS

The scales demonstrated acceptable psychometric properties and construct validity.

IMPLICATIONS FOR PRACTICE

This study validated the Chinese version of the Generic Core Scales among pediatric cancer patients and their caretakers, which supports the future use of the scales in clinical settings. The Generic Core Scales can also be supplementary to the PedsQL Cancer Module for measuring multiple domains of quality of life in cancer population.

Measuring and valuing health-related quality of life among children and adolescents in mainland China--a pilot study

Background

The Child Health Utility 9D (CHU9D), a new generic preference-based health-related quality of life (HRQoL) instrument, has been validated for use in young people in both the UK and Australia. The main objectives of this study were to examine the feasibility of using a Chinese version of the CHU9D (CHU9D-CHN) to assess HRQoL and to investigate the association of physical activity, homework hours and sleep duration with HRQoL in children and adolescents in Mainland China.

Methods

Data were collected using a multi-stage sampling method from grades 4–12 students in May 2013 in Nanjing, China. Consenting participants (N = 815) completed a self-administered questionnaire including the CHU9D-CHN instrument and information on physical activity, homework and sleep duration, self-reported health status, and socio-demographic characteristics. Descriptive and multivariate linear regression analyses were undertaken. CHU9D-CHN utility scores were generated by employing two scoring algorithms currently available for the instrument, the first derived from UK adults utilising the standard gamble (SG) valuation method and the second derived from Australian adolescents utilising the best-worst scaling (BWS) method.

Results

It was found that CHU9D utility scores discriminated well in relation to self-reported health status and that better health status was significantly associated with higher utility scores regardless of which scoring algorithm was employed (both p<0.001). The adjusted mean utilities were significantly higher for physically active than inactive students (0.023 by SG, 0.029 by BWS scoring methods, p<0.05). An additional hour of doing homework and sleep duration were, separately, associated with mean utilities of −0.019 and 0.032 based on SG, and −0.021 and 0.040 according to BWS scoring algorithms (p<0.01).

Conclusion

The CHU9D-CHN shows promise for measuring and valuing the HRQoL of children and adolescents in China. Levels of self-reported physical activity, homework and sleep time were important influencers of utility scores.

Considering quality of life for children with cancer: a systematic review of patient-reported outcome measures and the development of a conceptual model

OBJECTIVES

An appraisal of pediatric cancer-specific quality-of-life (QOL) instruments revealed a lack of clarity about what constitutes QOL in this population. This study addresses this concern by identifying the concepts that underpin the construct of QOL as determined by a content analysis of all patient-reported outcome (PRO) instruments used in childhood cancer research.

METHODS

A systematic review was performed of key databases (i.e., MEDLINE, CINAHL, PsychINFO) to identify studies of QOL in children with cancer. A content analysis process was used to code and categorize all items from generic and cancer-specified PRO instruments. Our objective was to provide clarification regarding the conceptual underpinnings of these instruments, as well as to help inform the development of theory and contribute to building a conceptual framework of QOL for children with cancer.

RESULTS

A total of 6,013 English language articles were screened, identifying 148 studies. Ten generic and ten cancer-specific PRO instruments provided 957 items. Content analysis led to the identification of four major domains of QOL (physical, psychological, social, and general health), with 11 subdomains covering 98 different concepts. While all instruments reflected items relating to the broader domains of QOL, there was substantial heterogeneity in terms of the content and variability in the distribution of items.

CONCLUSIONS

This systematic review and the proposed model represent a useful starting point in the critical appraisal of the conceptual underpinnings of PRO instruments used in pediatric oncology and contribute to the need to place such tools under a critical, yet reflective and analytical lens.

Health related quality of life assessment in Pakistani paediatric cancer patients using PedsQL™ 4.0 generic core scale and PedsQL™ cancer module

BACKGROUND

The purpose of the study was to evaluate and compare the HRQOL of paediatric cancer in comparison to the healthy children across age groups, using PedsQLTM 4.0 Generic Core Scales and the PedsQL™ Cancer Module.

METHOD

The PedsQLTM 4.0 Generic Core Scales and PedsQL Cancer Module 3.0 were administered on 56 children including 26 cancer patients and 30 healthy children while employing self and proxy report forms. Furthermore, the results were compared with their healthy comparison group.

RESULTS

The results indicated a significant relationship between HRQOL reports of cancer patients and their parents. However, the mean of paediatric cancer patients is significantly lower as compare to their healthy comparison group. The mean of proxy report is lower overall on both PedsQL and PedsQL cancer module reports.

CONCLUSION

Conclusively, overall HRQOL of cancer patients was lower than healthy children but it is quite similar to their parents' perception. Whereas, the parental mean on PedsQL and PedsQL 3.0 Cancer Module are significantly low. The study indicated a marked difference between cancer patients and healthy children's HRQOL perception and unfortunately in country like Pakistan where cancer is on increase, no significant work has yet been done to explore this area of research. The present study highlighted the need to focus on the particular psychological health services required to serve the physically challenged population.

Validation of the Japanese version of the Pediatric Quality of Life Inventory (PedsQL) Cancer Module

Background

The PedsQL 3.0 Cancer Module is a widely used instrument to measure pediatric cancer specific health-related quality of life (HRQOL) for children aged 2 to 18 years. We developed the Japanese version of the PedsQL Cancer Module and investigated its reliability and validity among Japanese children and their parents.

Methods

Participants were 212 children with cancer and 253 of their parents. Reliability was determined by internal consistency using Cronbach's coefficient alpha and test-retest reliability using intra-class correlation coefficient (ICC). Validity was assessed through factor validity, convergent and discriminant validity, concurrent validity, and clinical validity. Factor validity was examined by exploratory factor analysis. Convergent and discriminant validity were examined by multitrait scaling analysis. Concurrent validity was assessed using Spearman's correlation coefficients between the Cancer Module and Generic Core Scales, and the comparison of the scores of child self-reports with those of other self-rating depression scales for children. Clinical validity was assessed by comparing the on- and off- treatment scores using Kruskal-Wallis and Mann-Whitney U tests.

Results

Cronbach's coefficient alpha was over 0.70 for the total scale and over 0.60 for each subscale by age except for the 'pain and hurt' subscale for children aged 5 to 7 years. For test-retest reliability, the ICC exceeded 0.70 for the total scale for each age. Exploratory factor analysis demonstrated sufficient factorial validity. Multitrait scaling analysis showed high success rates. Strong correlations were found between the reports by children and their parents, and the scores of the Cancer Module and the Generic Core Scales except for 'treatment anxiety' subscales for child reports. The Depression Self-Rating Scale for Children (DSRS-C) scores were significantly correlated with emotional domains and the total score of the cancer module. Children who had been off treatment over 12 months demonstrated significantly higher scores than those on treatment.

Conclusions

The results demonstrate the reliability and validity of the Japanese version of the PedsQL Cancer Module among Japanese children.
