Abstract
PURPOSE The purposes of this study were to examine the relationships among maternal and environmental variables in the first 6 months postpartum and toddler health status, and to identify predictors of toddler health. DESIGN AND METHODS A secondary analysis was conducted on an existing dataset of a longitudinal parent-child survey. RESULTS Maternal stress predicted 8% of the variance in child health status at 18 months of age. Children in nonparental care more than 20 hr per week were perceived as less healthy. PRACTICE IMPLICATIONS Pediatric nurses should assess levels of maternal stress in the early months postpartum and anticipate poorer health status in toddlers who spend more than 20 hr per week in nonparental care.

Effect of dexamethasone on quality of life in children with acute lymphoblastic leukaemia: a prospective observational study. Health Qual Life Outcomes 2008; 6:103. [PMID: 19036151 PMCID: PMC2640370 DOI: 10.1186/1477-7525-6-103] [Citation(s) in RCA: 37] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2008] [Accepted: 11/26/2008] [Indexed: 11/30/2022] Open
Abstract
Background Glucocorticoids are important in the treatment of childhood acute lymphoblastic leukaemia (ALL). However, cyclic administration of high dose glucocorticoids may cause rapid and substantial changes in quality of life (QoL). The maintenance phase of the Dutch ALL-9 protocol consisted of alternating two weeks on and five weeks off dexamethasone (6 mg/m2/day). The present study was performed to assess the effect of dexamethasone on QoL during treatment for ALL according to this protocol. Methods In a multicentre prospective cohort study, QoL was assessed halfway (T1) and at the end of the two-year treatment (T2). A generic (Child Health Questionnaire) and disease specific (PedsQL™ cancer version) QoL questionnaire were used to assess QoL in two periods: on and off dexamethasone, respectively. Results 41 children (56% males) were evaluated, mean age at diagnosis was 5.6 years. The CHQ physical and psychosocial summary scores were significantly lower than population norms. At T1 and T2, overall QoL showed no significant change. However, regarding specific domains (pain, cognitive functioning, emotion/behaviour and physical functioning) QoL decreased over time. QoL was significantly more impaired during periods on dexamethasone. Conclusion Dexamethasone was associated with decreased QoL. At the end of treatment, reported QoL during dexamethasone deteriorated even more on certain scales (pain, cognitive functioning, emotion/behaviour and physical functioning). Knowledge of the specific aspects of QoL is essential to improve counselling and coping in paediatric oncology. Adverse effects of specific drugs on QoL should be taken into account when designing treatment protocols.

Abstract
BACKGROUND The objective of this analysis was to evaluate the psychometric properties of a brief scale developed to assess the degree of difficulties in children with Attention-Deficit/Hyperactivity Disorder (ADHD). The Global Impression of Perceived Difficulties (GIPD) scale reflects overall impairment, psychosocial functioning and Quality of Life (QoL) as rated by patient, parents and physician at various times of the day. METHODS In two open-label studies, ADHD-patients aged 6-17 years were treated with atomoxetine (target-dose 0.5-1.2 mg/kg/day). ADHD-related difficulties were assessed up to week 24 using the GIPD. Data from both studies were combined to validate the scale. RESULTS Overall, 421 patients received atomoxetine. GIPD scores improved over time. All three GIPD-versions (patient, parent, physician) were internally consistent; all items showed at least moderate item-total correlation. The scale showed good test-retest reliability over a two-week period from all three perspectives. Good convergent and discriminant validity was shown. CONCLUSION GIPD is an internally consistent, reliable and valid measure to assess difficulties in children with ADHD at various times of the day and can be used as indicator for psychosocial impairment and QoL. The scale is sensitive to treatment-related change.

Abstract
Outcomes are, simply put, why a surgeon comes to work each day. For decades, surgeons have insisted on a regular self-examination of outcomes to ensure the optimal treatment of our patients. Clinical research in pediatric surgery has largely subsisted on outcome analysis as it relates to the rudimentary end-result of an operation, utilizing variables such as mortality, operative time, specific complication rates, and hospital length of stay to name a few. Recently, outcomes research has become a more complex endeavor. This issue of Seminars in Pediatric Surgery addresses a wide array of these newfound complexities in contemporary outcomes research. The purpose of this review is to assist the pediatric surgeon in understanding the tools that are used in contemporary outcomes research and to be able to use this information to ask new questions of our patients and ourselves as we continue to strive for excellence in caring for sick infants and children.

Abstract
OBJECTIVE Our objective was to review measures of health-related quality of life (HRQL) for long-term follow up in children after major trauma and to determine the measures that are suitable for a large age range, reliable and valid, and cover a substantial amount of the domains of functioning using the International Classification of Functioning, Disability, and Health (ICF) of the World Health Organization (WHO). METHODS The Medline and EMBASE databases were searched in all years up to October 2007 for generic HRQL measures suitable for children aged 5-18 years old and validated in English or Dutch. Measures were reviewed with respect to the age range for which the measure was suitable and reliability, validity, and content related to the ICF. RESULTS The search resulted in 1,235 hits and 21 related articles. Seventy-nine papers met the inclusion criteria, describing in total 14 measures: Child Health and Illness Profile Adolescent and Child Edition (CHIP-AE/CE), Child Health Questionnaire Child and Parent Forms (CHQ-CF87/PF50/PF28), DISABKIDS, Functional Status II (FS II)(R), Health Utilities Index Mark 2 (HUI 2), KIDSCREEN 52/27, KINDL, Pediatric Quality of Life Inventory (PedsQL), TNO Institute of Prevention and Health and the Leiden University Hospital (TNO-AZL), TNO-AZL Children's Quality Of Life (TACQOL), and Youth Quality of Life Instrument--Research Version (YQOL-R). Measures that were suitable for a large age range were CHQ-PF50/PF28, DISABKIDS, FS II(R), HUI 2, KIDSCREEN, PedsQL, and TACQOL. All measures had moderate to good psychometric properties, except for CHQ-PF50/PF28, KINDL, and TACQOL, which had either low internal consistency or bad test-retest reliability. The measures that covered more than six chapters of the ICF domains were CHIP-AE/CE, CHQ-CF87/PF50, DISABKIDS, KIDSCREEN-52, PedsQL, and TACQOL. CONCLUSIONS DISABKIDS, KIDSCREEN 52, and PedsQL are suitable for long-term follow-up measurement of HRQL in children after major trauma. They cover a large age range, have good psychometric properties, and cover the ICF substantially.

Abstract
BACKGROUND Information regarding changes in the health-related quality of life (HRQL) of children during chemotherapy is scarce. Furthermore, there exists a general lack of consensus as to which measures are best suited to assess changes in HRQL in this population. The purpose of this study is to compare the responsiveness of 3 pediatric HRQL measures: the Pediatric Quality of Life Inventory (PedsQL), the Child's Health Questionnaire (CHQ), and the Health Utilities Index (HUI). METHODS Consecutive pediatric oncology patients and their parents completed the questionnaires at 1-week intervals for a total of 4 weeks, starting on the third day of the patient's chemotherapy treatment cycle. RESULTS Twenty-nine patients were enrolled with the majority (62%) having a diagnosis of leukemia with an average age of 9 years. The parent proxy reports from time 1 to 4 showed a mean change in the PedsQL of 17 for the generic core scale and 12 for the cancer specific module. The mean change in CHQ physical functioning scale was 6, while the psychosocial scale was only 2, while the HUI 2 was 3 (x100), and HUI 3 was 4 (x100). There was significantly more change in the PedsQL generic scores when compared with the HUI 2 and 3 and the CHQ psychosocial scale (P<0.01). CONCLUSIONS When measuring HRQL repeatedly in a heterogeneous population, the PedsQL is the measure most responsive to change.

Abstract
OBJECTIVE To assess health consequences and health-related quality of life (HR-QoL) in children with meningococcal septic shock up to 2 yrs after discharge from the pediatric intensive care unit and to assess their parents. To determine major predictors of that outcome. PATIENTS AND METHODS A prospective cohort study. Follow-up of all consecutive children with septic shock and purpura requiring intensive care treatment between 2001 and 2005, and their parents. HR-QoL was assessed with the Child Health Questionnaire (children) and Medical Outcomes Study 36-item Short-Form Health Survey (parents). RESULTS Of 53 eligible families, 47 participated (28 boys/19 girls; median age at the time of pediatric intensive care unit admission, 3.7 yrs; median Pediatric Risk of Mortality score, 21). A total of 26 children (55%) had scars as a result of skin necrosis; two (4%) had amputation of a digit or digits. In 21 children (45%), chronic complaints were reported. Children with and without chronic complaints did not differ significantly with regard to severity of illness and age at the time of pediatric intensive care unit admission. Significantly lower scores were found on HR-QoL scales concerning mainly physical functioning and health perception in comparison with normative data. There was a significant negative association between severity of illness and the HR-QoL scale concerning physical functioning. Children with chronic complaints had significantly lower scores on the HR-QoL scale concerning pain. Eight of 47 mothers (17%) at the time of the study had anxiety or depression requiring professional help. Mothers with and without these problems differed significantly with regard to age of their child at the time of pediatric intensive care unit admission. Parents showed significantly higher scores on HR-QoL scales concerning physical functioning and bodily pain in comparison with normative data. There was a significantly negative association between the presence of emotional problems and HR-QoL scores in mothers. CONCLUSIONS Up to 2 yrs after discharge from the pediatric intensive care unit, there is still a considerable effect on health and HR-QoL in children, especially on the physical scales. Severity of illness and chronic complaints negatively affected HR-QoL scales in children. Quite a few mothers suffered from emotional problems.

Abstract
Background This study was designed to develop a diabetes-specific questionnaire on parents' quality of life and satisfaction with their child's diabetes treatment, the WEll-being and Satisfaction of CAREgivers of Children with Diabetes Questionnaire, and to conduct psychometric validation of the WE-CARE. Methods Parents of 116 children aged 6 to 11 years were enrolled in the United States. Children had type 1 diabetes mellitus for > 1 year, had been treated with subcutaneous insulin for ≥ 2 months, and had a recent glycosylated hemoglobin (HbA1C) measurement. Recruiting clinicians provided clinical information on the children. Over a two-week period, parents completed WE-CARE (initial 68 items) and two other questionnaires (the 36-item Short Form of the Medical Outcomes Study and the 50-item Child Health Questionnaire-Parent Form) twice. Results A literature review and one-on-one interview with caregivers and pediatricians led to the development of a draft questionnaire consisting of 68 items. Factor analysis suggested retention of 37 of the 68 initial items grouped into four multi-item scales (Psychosocial Well-being, Ease of Insulin Use, Treatment Satisfaction, and Acceptance of Insulin Administration as well as a Total Score). The four multi-item domains of WE-CARE were found to be psychometrically robust – they had negligible floor and ceiling effects, excellent internal consistency and test-retest reliability, high item-discriminant validity and good concurrent, divergent, known-group and clinical validity. Moderate interscale correlations among the four WE-CARE domains indicated that the concepts they measure were related but distinct. Conclusion These data suggest that WE-CARE provides a reliable and valid measure of parents' well-being and treatment satisfaction related to their child's diabetes. While these results show promise, additional validation of WE-CARE is warranted.

Abstract
Rotavirus is the most common cause of gastroenteritis in children aged <5 years old, two new vaccines have recently been developed which can prevent associated morbidity and mortality. While apparently safe and efficacious, it is also important to establish whether rotavirus immunization is cost effective. A decision analytical model which employs data from a review of published evidence is used to determine the cost effectiveness of a rotavirus vaccine. The results suggest that some of the health sector costs, and all of the societal costs, of rotavirus gastroenteritis in children can be avoided by an immunization programme. The additional cost to the health sector may be considered worthwhile if there is a sufficient improvement in the quality-of-life of children and parents affected by gastroenteritis; this study did not find any evidence of research which has measured the utility gains from vaccination.

Abstract
OBJECTIVE To examine differences in health-related quality of life (HRQL) of children living in different socio-economic contexts in Australia. METHODS Parental reports describing the HRQL and socio-economic status of a random national sample of 3,597 school-age children were obtained using the Child Health Questionnaire (CHQ) and a standardised socio-economic interview. Response rate was 70%. RESULTS Children in families of higher income, whose parents had more years of schooling and were employed and children who lived in two-parent, original families had significantly higher HRQL across a range of domains assessed by the CHQ. CONCLUSION Children from lower socio-economic backgrounds in Australia have a significantly more negative experience of health and wellness. Such differences may well increase unless deliberate political attention is given to addressing the widening differences in relative wealth in Australia.

Abstract
In order to arrive at population-based estimates on the prevalence and characteristics of children and adolescents with specific health care needs (CSHCN), screening instruments focussing on the consequences of physical, mental and behavioral problems rather than on medical diagnoses have been developed. One of the most feasible and widely tested instruments, the CSHCN screener was added to the self-administered questionnaire for parents of children participating in the German Health Interview and Examination Survey for Children and Adolescents (KiGGS). The overall weighted prevalence of CSHCN was 16.0% among boys and 11.4% among girls. Children at kindergarten or school age were more than 2-3 times more likely to screen positive compared to toddlers. Up to 14 years, the sex difference persisted through all age groups and was most pronounced between the ages of 3 and 10 years. Children with a migrant background had significantly lower rates of CSHCN compared to non-migrants. This was particularly true for boys (8.0% vs. 17.1%). CSHCN status was not related to social status, urbanization or residence in former West vs. former East Germany. Except for the lack of association with social status, these results are in good accordance with observations from the US National Survey of CSHCN.

Abstract
OBJECTIVE The goal was to determine the clinical effectiveness of prolonged outpatient treatment with trimethoprim/sulfamethoxazole for children with chronic active otitis media. METHODS We performed a randomized, placebo-controlled trial with 101 children (1-12 years of age) with chronic active otitis media (defined as otorrhea for > or =12 weeks). In addition to a short course of steroid and antibiotic eardrops, children were assigned randomly to receive 6 to 12 weeks of orally administered trimethoprim/sulfamethoxazole (18 mg/kg, 2 times per day) or placebo and were monitored for 1 year. RESULTS At 6 weeks, 28% of children in the trimethoprim/sulfamethoxazole group and 53% of children in the placebo group had otomicroscopic signs of otorrhea. At 12 weeks, these values were 32% and 47%, respectively. At 1 year, the numbers of children with otorrhea were similar in the 2 groups (25% and 20%, respectively). One child in the trimethoprim/sulfamethoxazole group developed a skin rash. Vomiting or diarrhea was reported for 9% of the trimethoprim/sulfamethoxazole group and 2% of the placebo group. Pure-tone hearing levels and health-related quality of life improved during the study but did not differ between the trimethoprim/sulfamethoxazole group and the placebo group. Pseudomonas aeruginosa was the most frequently isolated bacteria in the otorrhea samples from both groups. CONCLUSIONS A 6- to 12-week course of high-dose, orally administered trimethoprim/sulfamethoxazole therapy is beneficial for children with chronic active otitis media. The treatment effect is most pronounced with the shorter course and disappears if administration of the medication is discontinued.

Abstract
OBJECTIVE To evaluate feasibility, internal consistency, test-retest reliability, and concurrent and discriminative validity of the Infant and Toddler Quality of Life Questionnaire (ITQOL) for parents of pre-school children with 12 scales (103-items) covering physical and psychosocial domains and impact of child health on parents, in comparison with the TNO-AZL Pre-school Children Quality of Life Questionnaire (TAPQOL). METHODS Parents of children from a random general population sample (2 months-4 years old; n = 500) and of an outpatient clinic sample of children with respiratory disease (5 months-[Formula: see text] years old; n = 217) were mailed ITQOL and TAPQOL questionnaires; a retest was sent after two weeks. RESULTS Feasibility: The response was >or=80% with few missing and non-unique ITQOL-answers (<2%) in both study populations. Some ITQOL-scales (3-4 scales) showed a ceiling effect (>25% at maximum score). Internal consistency: All Cronbach's alpha >0.70. Test-retest Intraclass Correlation Coefficients (ICCs) were moderate or adequate (>or=0.50; p < 0.01) for 10 ITQOL-scales. VALIDITY ITQOL-scales, with a few exceptions, correlated better with predefined parallel TAPQOL scales than with non-parallel scales. Five to eight ITQOL-scales discriminated clearly between children with few and with many parent-reported chronic conditions, between children with and without doctor-diagnosed respiratory disease and with a low and a high parent-reported medical consumption (p < 0.05). CONCLUSIONS This study supported the evidence that the ITQOL is a feasible instrument with adequate psychometric properties. The study provided reference ITQOL scores for gender/age subgroups. We recommend repeated evaluations of the ITQOL in varied populations, especially among very young children, including repeated assessments of test-retest characteristics and evaluations of responsiveness to change. We recommend developing and evaluating a shortened ITQOL version.

Abstract
BACKGROUND Scientific knowledge on functional outcome after injury is limited. During the past decade, a variety of measures have been used at various moments in different study populations. Guidelines are needed to increase comparability between studies. METHODS A working group of the European Consumer Safety Association conducted a literature review of empirical studies into injury-related disability (1995-2005). We included injury from all levels of severity and selected studies using generic health status measures with both short-term and long-term follow up. The results were used as input for a consensus procedure toward the development of guidelines for defining the study populations, selecting the health status measures, selecting the timings of the assessments, and data collection procedures. RESULTS The group reached consensus on a common core of health status measures and assessment moments. The group advises to use a combination of EuroQol-5D and Health Utilities Mark III in all studies on injury-related disability. This combination covers all relevant health domains, is applicable in all kinds of injury populations and in widely different age ranges, provides a link with utility scores, and has several practical advantages (e.g., brevity, availability in different languages). For specific types of injury, the common core may be supplemented by injury-specific measures. The group advises a common core of assessments at 1, 2, 4, and 12 months after injury. CONCLUSIONS Our guidelines should be tested and may lead to improved and more consistent epidemiologic data on the incidence, severity, and duration of injury-related disability.

ANIMALS 108 dogs with chronic degenerative joint disease and 26 healthy dogs. PROCEDURES Questionnaire responses were subjected to factor analysis (FA) and questionnaire scores to discriminant analysis to evaluate construct validity. Questionnaire scores were used to explore the potential of this instrument for minimizing respondent bias and for evaluative purposes. RESULTS FA results revealed a sensible factor structure accounting for 65% of the variance in data, with factors identifiable as domains of HRQL in dogs affected by chronic pain. Further evidence for construct validity was provided when questionnaire scores were used to discriminate, on the basis of 218 questionnaires, between dogs with clinician-awarded pain scores of 0 and dogs with pain scores >or= 1 (88% discrimination, with 95% of no-pain group dogs and 87% of some-pain group dogs correctly categorized). Use of the questionnaire provided minimized respondent bias. CONCLUSIONS AND CLINICAL RELEVANCE Validation of the questionnaire as an instrument for discriminative and evaluative measurements of orthopedic chronic pain through its impact on HRQL in dogs was provided. Use of the questionnaire, with further testing and refinement, may support improved clinical decision making, facilitate development of evidence-based therapeutic options for chronic diseases, and help veterinarians and owners define humane end points in dogs. IMPACT FOR HUMAN MEDICINE Information gained here may provide improved measurements of clinical change in animal studies that use dogs with naturally occurring chronic pain to evaluate novel human treatment protocols.

Abstract
INTRODUCTION Assessing outcomes in the paediatric trauma population is important. Identifying suitable instruments can be problematic. This article highlights the commonly used outcome measures for assessing functional status and health related quality of life in paediatric trauma patients. Child specific characteristics which impact upon instrument development and selection are reviewed. METHODS An electronic database search was conducted to identify suitable English language measures used for outcome assessment in paediatric trauma patients from 1966 to present. RESULTS Nine suitable instruments were identified, the child health questionnaire (CHQ), Glasgow outcome scale (GOS), paediatric overall performance category (POPC), PedsQL 4.0 generic core scales, paediatric evaluation of disability inventory (PEDI), functional independence measure (FIM), WeeFIM and an unnamed paediatric trauma specific measure [Gofin R, Hass T, Adler B, The development of disability scales for childhood and adolescent injuries. J Clin Epidemiol 1995;48:977-84]. Each instrument was found to have advantages and disadvantages for assessing outcomes in a paediatric trauma population. CONCLUSION The PedsQL 4.0 generic core scale could be feasible for administration as a routine outcome measure for paediatric trauma groups. For very young children an additional measure such as that proposed by Gofin et al. [Gofin R, Hass T, Adler B, The development of disability scales for childhood and adolescent injuries. J Clin Epidemiol 1995;48:977-84] may be indicated. Future use of these instruments in the paediatric population would benefit from further psychometric evaluation.

Abstract
OBJECTIVE The goal was to measure, by using the Health Utilities Index, the health status of children 6 months after admission to PICUs in the United Kingdom. METHODS All PICUs in the United Kingdom were invited to participate. Children who were > or = 6 months of age at admission and were discharged alive from participating units during a 1-year period were eligible for this study. Children with completed consent forms who had survived to 6 months after admission received the Health Utilities Index questionnaire. RESULTS Admission data on 7214 admissions to 22 units were collected between March 2001 and February 2002. Of those patients, 6786 survived to unit discharge, and consent for follow-up contact was obtained for 2642. At 6 months after admission, the mortality rate was estimated at 11.1% and 2034 children were still alive and contactable. Of those children, Health Utilities Index questionnaires were returned by 1455. No impairment was indicated for 767, 951, 940, 919, 962, and 939 children with respect to the Health Utilities Index sensation, cognition, emotion, pain, mobility, and self-care attributes, respectively. The mean +/- SE Health Utilities Index utility score was 0.73 +/- 0.01, with 397 children (27.3%) in full health. CONCLUSIONS Death after pediatric intensive care in the United Kingdom is uncommon, making assessment of health status important. At 6 months after admission, there is significant morbidity. To assess the impact of strategies to improve or to optimize care on longer-term outcomes, standardized collection of data on preexisting comorbidities and illness severity is required.

Abstract
The American Burn Association/Shriners Hospital for Children Burn Outcomes Questionnaire (BOQ) is a self-administered questionnaire to monitor functional outcome after burns in children and adolescents. This study aimed to assess feasibility, reliability, and validity of the Dutch BOQ. The BOQ was adapted into Dutch and tested in a population of children and adolescents aged 5 to 15 years who were primary admissions to a Dutch or Belgian burn center (n = 6) during the period of March 2001 through February 2004. To assess validity, the Child Health Questionnaire (CHQ) and the EuroQol-5D (EQ-5D) were included. Response rate was 53% among parents (n = 145) and 48% among adolescents (n = 52). Internal consistency of the BOQ scales was good (Cronbach's alpha >0.7 in all but one scale). Test and retest results were similar; there were no significant differences between parents and adolescents in this respect. Expected high correlations between BOQ scales and conceptually equivalent CHQ and EQ-5D scales were found in eight of 12 comparisons. Eleven scales showed significant differences in the expected direction between children with a long length of stay versus those with a short length of stay. The Dutch BOQ can be used to evaluate functional outcome after burns in children aged 5 years and older. Our study showed that the Dutch BOQ is a feasible instrument with good reliability and validity.

Abstract
Pre-school children are frequently affected by wheezing illness, with substantial influences on their health-related quality of life (HRQL). The Infant/Toddler Quality of Life Questionnaire (ITQOL) is the only generic health status measure for children aged 2 months up to 5 years. In this present study we evaluated the impact of wheezing illness in pre-school children on the HRQL, using the ITQOL. A questionnaire including the ITQOL and ISAAC questions on frequency and severity of respiratory complaints were sent to parents of patients aged 6 months-5 years visiting the outpatient department with wheezing illness. Scale scores of ITQOL of the included children were compared with general population scores. Using multivariate analysis, the influence of general and clinical characteristics on ITQOL scale scores was evaluated. Results are based on 138 children, 59% male, mean age 34 months. Children with wheezing illness scored differently to the general population sample on 8 of the 11 ITQOL scales. Age, comorbidity and employment of the respondent affected scales on child's physical and emotional functioning and parental functioning. Severity of dyspnoea and wheezing, presence of cough, corticosteroid use, and number of GP visits negatively affected scales on the child's physical and emotional functioning. In conclusion, the HRQL as measured by the ITQOL was lower in a group of Dutch pre-school children with wheezing illness compared to a general population sample. The scale scores were sensitive to age, co morbidity, socio-economic situation, and disease severity.

Abstract
PURPOSE This article investigates the meaning of subjective health assessments for younger respondents by examining the temporal stability of self-rated health (SRH) among adolescents. Two competing understandings of SRH are tested: SRH as a spontaneous health assessment or as an enduring self-concept. METHODS Using data from two waves of the National Longitudinal Study of Adolescent Health (n = 13,511), an intra-class correlation coefficient and a weighted Kappa estimate are calculated to assess the test-retest reliability for SRH. Self-rated health (T2) is then modeled as a function of SRH (T1), physical health (T1), and mental health (T1), and changes in physical and mental health (T2-T1). RESULTS SRH is found to be moderately stable over repeated observations (K = .40; rho = .55) among adolescents. Findings from multivariate analyses suggest that SRH (T2) is largely determined by SRH (T1) and less so by changes in physical or psychological health status (T2-T1). CONCLUSIONS SRH among adolescents is in part a spontaneous health assessment but it is best understood as an enduring self-concept.

Abstract
AIMS To date there have not been any generic or continence-specific measurement tools that allow clinicians to investigate quality of life in children with bladder dysfunction. The aim of this research was to create a cross-cultural tool to assess and measure the wider psychosocial impact of current and new interventions for bladder dysfunction in children. MATERIALS AND METHODS The study was conducted in three parts: expert consultation with continence clinicians; design and administration of a child-completed international questionnaire; item analysis, validity and reliability testing, and design of a new tool. RESULTS The need for a pediatric incontinence QoL measure evaluation was strongly endorsed by clinicians. Data from 156 child-completed questionnaires collected in 10 countries was analyzed for item characteristics and found to be free of item correlation and ceiling and floor effects. Factor analysis revealed 2 factors, which were labeled intrinsic and extrinsic. Rasch analyses showed the internal validity of both subscales was reasonable good. Cronbach's alpha for each factor was 0.91 and 0.72. After analysis, items were selected for the new tool, PinQ, and evaluated for ambiguity, clarity, comprehension level required, choice of words and phrases, and age-appropriate concepts. Twenty-one items were finally selected and randomly positioned within the tool. CONCLUSIONS A cross-cultural tool that quantifies the holistic effect of bladder dysfunction in children has been designed and tested for validity.

Abstract
The health-related quality of life (HR-QOL) of children and adolescents is increasingly considered a relevant topic for research. Instruments to assess quality of life in children and adolescents of a generic as well as disease- or condition-specific nature are being developed and applied in epidemiological surveys, clinical studies, quality assurance and health economics. This paper attempts to give an overview on the state of the art of HR-QOL assessment in children as it relates to methodological and conceptual challenges. Instruments available in international or cross-cultural research to assess HR-QOL in generic terms were identified and described according to psychometric data provided and the width of application. In an initial literature search, several challenges in the assessment of child and adolescent HR-QOL were identified, ranging from conceptual and methodological to practical aspects. Seven specific major issues were considered: (i) What are the dimensions of HR-QOL relevant for children and adolescents, and do suitable instruments for their measurement exist? (ii) Can these dimensions be collected in a cross-culturally comparable way? (iii) What advantages and disadvantages do self-rated versus externally evaluated HR-QOL measurements of children and adolescents have? (iv) How can HR-QOL be assessed in an age-appropriate way? (v) What are the advantages and disadvantages of disease-specific and generic data collection? (vi) What advantages and disadvantages do profile and index instruments have? (vii) How can HR-QOL be connected with utility- preference values? In a second literature search we identified nine generic HR-QOL instruments and four utility health state classification systems that complied with the prespecified inclusion criteria. It was concluded that (i) HR-QOL instruments are available to assess the dimensions of the construct relevant to children and adolescents; (ii) provided that an instrument was constructed in an appropriate way, the dimensions of HR-QOL can be measured in an interculturally comparable manner; (iii) the HR-QOL of children and adolescents can and should be ascertained by self-rating; (iv) the measurement instruments used have to consider maturity and cognitive development; (v) only generic quality-of-life instruments allow for an assessment of HR-QOL in both healthy and chronically ill children and adolescents; (vi) the representation of HR-QOL achieved through a singular index value is connected to strict psychometric conditions: the index instrument has to be tailored to these psychometric conditions; (vii) how far utility measures are employable with children and adolescents has to be investigated in further studies. The problem aspects identified indicate the necessity for further research. Nevertheless, instruments for assessing the HR-QOL of children and adolescents can be identified that meet the requirements mentioned above.

Abstract
This study addressed the comparability of data obtained from a student-based and parent-based asthma and respiratory health survey. Our goal was to ascertain whether there were meaningful and systematic differences in asthma classification based on symptom and diagnosis reports obtained separately from students and their parents. A brief, written survey, based on the International Study of Asthma and Allergy in Children questionnaire, was administered to 6th through 10th grade students in two schools in Oakland, CA, USA. Students who reported asthma-like indicators for the previous 12-month period were defined as positive and a more extensive questionnaire was mailed home to those parents. A more refined classification of asthma based on parent report of indicators was compared with student report. Forty-four percent of 1298 students were classified as positive for current asthma-like symptoms and 50% of parent surveys were returned. For the positive students with parent surveys, 59% were classified as 'probable' for asthma based on the parent survey. Overall, the agreement between parent and students' classification was 70%, and 83% for students with a parent report of physician diagnosis of asthma. Students who were discordant with parents for physician diagnosis of asthma were more likely to be male, and more likely to have a parent report of unscheduled Emergency Department visit for wheezing or trouble breathing. Findings indicated that with the exception of medication, students reported asthma indicators more frequently that parents, independent of classification. Student report of physician diagnosis with a 12-month report of an asthma symptom was determined to be a good indicator of probable current asthma. Inclusion of or reliance on a parental questionnaire is not likely to improve the reliability of a school-based asthma surveillance program in our population.

Abstract
OBJECTIVES To assess the impact of obesity on quality of life (QOL) in black and white adolescents. STUDY DESIGN One hundred ten overweight (body mass index [BMI], 41.7 +/- 8.9 kg/m2) and 34 nonoverweight adolescents (BMI, 20.6 +/- 2.9 kg/m2) and their parents completed measures of QOL. RESULTS Overweight was associated with poorer adolescent-reported QOL and parent reports of their children's QOL. Examining groups by weight status and race, overweight whites reported the greatest impairment on Social/Interpersonal, Self-Esteem, and Physical Appearance QOL (all P < .01), whereas parents of overweight blacks reported the poorest General Health Perceptions scores regarding their children. Interactions between BMI z-score and race were detected for Social/Interpersonal, Self-esteem, Daily Living, Self-Efficacy, Self-regard, and Physical Appearance QOL (all P < .05): Higher BMI in whites was associated with greater impairments in QOL than in blacks. Parents reported similar relations for their children. CONCLUSIONS According to adolescent and parent reports, overweight is associated with poorer QOL in adolescence, regardless of race; however, compared with overweight white adolescents, blacks report less impairment in QOL. Future research is required to determine whether differences in QOL are predictive of treatment success.

Abstract
The objectives of this study were to describe health-related quality of life of postmeningitic children and to examine the association between academic and/or behavioral limitations and health-related quality of life. One hundred and eighty-two children (mean age 9.7 years; range 5.3-14.2) were selected randomly from a cohort of 674 school-age children who recovered from non-Haemophilus influenzae type B bacterial meningitis. These children had neither meningitis with 'complex onset', nor prior cognitive or behavioral problems, nor severe disease sequelae. On average 7.4 years after meningitis, they were evaluated using an 'Academic Achievement Test' and their parents filled in the Child Behavior Checklist, the Child Health Questionnaire, and the Health Utilities Index. The long-term incidence of academic and/or behavioral limitations was 32%. Overall health-related quality of life of the postmeningitic children was decreased in comparison with that of a reference population of schoolchildren. The group of postmeningitic children with academic and/or behavioral limitations showed the most marked decrease in quality of life, especially concerning psychosocial health, cognition and family life. The negative effects on quality of life were not significantly influenced by age, gender, causative pathogen, presence of minor neurological impairment, or presence of hearing impairment. In conclusion, health-related quality of life of postmeningitic children is decreased, particularly of those with academic and/or behavioral limitations.

Abstract
AIMS To describe and quantify impairment in an outpatient population of children with chronic pain of unknown origin (UCP). METHODS A total of 149 children who presented with pain of at least three months' duration and without a satisfactory explanation at presentation were studied. Number of somatic complaints (Children's Somatisation Inventory, CSI), pain intensity (VAS, 0-10 cm), functional disability (Child Health Questionnaire (CHQ-CF) and clinical history), and general health perceptions (CHQ) were determined. RESULTS Mean age of the children was 11.8 years; 73% were girls. Overall, 72% suffered impairment in sports activities, 51% reported absence from school, 40% experienced limitations in social functioning, and 34% had problems with sleeping. Mean number of somatic symptoms differed significantly between boys (8.4) and girls (10.7). The CHQ-CF scores for physical functioning, role/social functioning, and general health perceptions were 76.4, 70.7, and 57.5, respectively, indicating substantial impairment on all domains. The mean pain intensity was 4.7 for current and 7.1 for worst pain. Children solely evaluated by a general practitioner prior to referral reported less, though still substantial, impairment. Low general health perceptions, impaired role/social functioning, high pain intensity, and having headache or musculoskeletal pain were independent predictors of having significant impairment. CONCLUSIONS Referred children with UCP show substantial impairment on multiple domains in daily life.

Abstract
BACKGROUND Indications for extracorporeal membrane oxygenation therapy have expanded to include cardiopulmonary arrest and support after congenital heart surgery. Data from a national registry have reported that cardiac patients have the poorest survival of all extracorporeal membrane oxygenation recipients. Concerns have been raised about the appropriateness of such an aggressive strategy, especially in light of the high costs and potential for long-term neurologic disability. We reviewed our experience with salvage cardiac extracorporeal membrane oxygenation to determine the cost-utility, which accounts for both costs and quality of life. METHODS Medical records of patients with congenital heart disease receiving salvage cardiac extracorporeal membrane oxygenation between January 2000 and May 2004 were reviewed. Charges for all medical care after the institution of extracorporeal membrane oxygenation were determined and converted to costs by published standards. The quality-of-life status of survivors was determined with the Health Utilities Index Mark II. RESULTS Salvage cardiac extracorporeal membrane oxygenation was instituted in 32 patients (18 for cardiopulmonary arrest and 14 for cardiac failure after heart surgery) at a median age of 2.0 months (range, 4 days to 5.1 years). Congenital heart disease was present in 27 (84%). The mean duration of extracorporeal membrane oxygenation support was 5.1 +/- 4.1 days. Survival to hospital discharge was 50%, including 1 patient bridged to heart transplantation. Survival to 1 year was 47%. The mean score of the Health Utilities Index for the survivors was 0.75 +/- 0.19 (range, 0.41-1.0). The median cost for hospital stay after the institution of extracorporeal membrane oxygenation was USD 156,324 per patient. The calculated cost-utility for salvage extracorporeal membrane oxygenation in this population was USD 24,386 per quality-adjusted life-year saved, which would be considered within the range of accepted cost-efficacy (< USD 50,000 per quality-adjusted life-year saved). CONCLUSIONS Salvage cardiac extracorporeal membrane oxygenation results in reasonable survival and is justified on a cost-utility basis.

Abstract
BACKGROUND AND OBJECTIVES The use of complementary and alternative medicines (CAM) is becoming increasingly popular. Although considered beneficial by users, the potential for interaction or substitution with conventional treatment should not be overlooked by health care professionals. It is therefore important to gain insight into the prevalence and the factors related to the use of CAM. To establish the prevalence of use of CAM among children with cancer treated in a large pediatric hospital, describe the profile of use and factors related with use. As a secondary objective we aimed at measuring quality of life of the children aged 5 or more and compare the scores between users and non-users. METHODS The study is a cross-sectional survey of parents whose child was treated at the oncology clinic or ward of Sainte-Justine Hospital, a large pediatric hospital in Montreal. Data on socio-demographic variables, the use of CAM and the quality of life was collected through a self-administered questionnaire. Quality of life was measured with the Child Health Questionnaire CHQ-PF50, while clinical data was collected from medical records. RESULTS A total of 115 patients were recruited and 92 parents completed and returned the questionnaire, resulting in a 80% response rate. According to this survey, 49% of the children used at least one type of CAM and 20% used herbal remedies/homeopathy/vitamins in the 2 months preceding the survey. Most popular CAM were spiritual/mental and physical strategies used by 35 and 33% of children under study, respectively. Only one parent reported having delayed a conventional treatment because of CAM. Although quality of life results must be interpreted with caution, they tend to favor non-users. CONCLUSIONS CAM is likely to be used by a wide variety of people. In our study, we found that about half of the children with cancer has used CAM in the 2 preceding months. No specific profile of CAM users emerged from this study. The high prevalence of CAM warrants further studies to better understand the reasons and consequences of CAM use particularly on quality of life.

Abstract
STUDY OBJECTIVES This study assessed the feasibility, reliability, and validity of the 28 item short child health questionnaire parent form (CHQ-PF28) containing the same 13 scales, but only a subset of the items in the widely used 50 item CHQ-PF50. DESIGN Questionnaires were sent to a random regional sample of 2040 parents of schoolchildren (4-13 years); in a random subgroup test-retest reliability was assessed (n = 234). Additionally, the study assessed CHQ-PF28 score distributions and internal consistencies in a nationwide general population sample of (parents of) children aged 4-11 (n = 2474) from Statistics Netherlands. MAIN RESULTS Response was 70%. In the school and general population samples seven scales showed ceiling effects. Both CHQ summary measures and one multi-item scale showed adequate internal consistency in both samples (Cronbach's alpha>0.70). One summary measure and one scale showed excellent test-retest reliability (intraclass correlation coefficient >0.70); seven scales showed moderate test-retest reliability (intraclass correlation coefficient 0.50-0.70). The CHQ could discriminate between a subgroup with no parent reported chronic conditions (n = 954) and subgroups with asthma (n = 134), frequent headaches (n = 42), and with problems with hearing (n = 38) (Cohen's effect sizes 0.12-0.92; p<0.05 for 39 of 42 comparisons). CONCLUSIONS This study showed that the CHQ-PF28 resulted in score distributions, and discriminative validity that are comparable to its longer counterpart, but that the internal consistency of most individual scales was low. In community health applications, the CHQ-PF28 may be an acceptable alternative for the longer CHQ-PF50 if the summary measures suffice and reliable estimates of each separate CHQ scale are not required.

Abstract
OBJECTIVE To assess the health-related quality of life (HRQoL) in children 1-2 years after they had sustained an injury. METHODS Parents of all children who were identified by the Queensland Trauma Registry during their admission to either of the two paediatric specialty hospitals in Brisbane, Australia, for the treatment of an injury, were invited to participate in this study. Parents who consented to participation received a copy of the Child Health Questionnaire (CHQ) that required them to provide information regarding their child's HRQoL following injury. The CHQ scores for the study respondents were compared with those of the Australian norms. This study was approved by the relevant ethics committees. RESULTS Two hundred and forty-one completed questionnaires were returned. The majority of cases were male (65%) and there was even representation across all age groups. The majority of injuries were considered to be minor (81%) and were predominantly the result of falls and cycling accidents causing mainly fractures and intracranial injury. On the majority of subscales of the CHQ, study participants recorded scores that were statistically significantly below those of the Australian norms. None of the relevant variables collected by the Queensland Trauma Registry were found to predict scores on the CHQ in this study (for those children hospitalized for > 24 h). CONCLUSION Injured children are worse off than their Australian counterparts in terms of HRQoL even up to 2 years following an injury. Further research needs to be undertaken to identify factors that predict lower HRQoL in order to reduce the burden of injury on children and their families.

Abstract
OBJECTIVE To conduct separate exploratory factor analyses (EFA) and confirmatory factor analyses (CFA) of the Child Health Questionnaire-Parent Form 50 (CHQ-PF-50) with a sample of children and adolescents with chronic conditions and physically healthy children seen in a pediatric setting. METHOD Parents of 329 children with chronic conditions including cancer, epilepsy, recurrent headache, inflammatory bowel disease (IBD), juvenile rheumatoid arthritis (JRA), sickle cell disease (SCD), and recurrent sleep disturbance and 332 physically healthy children completed CHQ-PF-50. RESULTS The EFA yielded a 27-item measure with seven factors for children with chronic conditions and a 28-item measure with eight factors for physically healthy children. Structural equation modeling procedures were used to conduct a second order CFA, which yielded the secondary factors of physical health and psychosocial health. A CFA yielded an excellent fit to the data for each group, but the models were different for each group. CONCLUSIONS CFA-derived models of the CHQ-PF-50 demonstrated construct validity for measuring the latent constructs of physical and psychosocial health in children and adolescents with chronic conditions and physically healthy children and adolescents. However, somewhat different factor solutions emerged for each group, suggesting that the specific domains assessed by the CHQ-PF-50 were not equivalent across groups. Findings have implications for applications of the CHQ-PF-50.

Abstract
Although numerous paediatric-based health-related quality-of-life (HR-QOL) instruments are currently in use, there still remain conceptual, methodological and developmental issues to address. This paper provides an up-to-date critical review of the HR-QOL literature in paediatric medicine. Our analysis indicates that there is no consensus on how HR-QOL and overall QOL should be defined and measured in children. It is recommended that future studies focus on operationalising and distinguishing these constructs from each other and from traditional health-status measures. A clear empirical basis for generating instrument items and for prioritising specific domains must be described. Researchers should consider using the data gathered during their first interviews as a springboard from which to test their ideas of HR-QOL and QOL, reformulate concepts and subsequently retest their notions before developing instruments. Related to methodological challenges, consistency and agreement are still used interchangeably when comparing child and parent reports of children's HR-QOL. The Pearson correlation is a measure of co-variation in scores, and not a measure of agreement. We recommend that researchers focus on determining agreement as opposed to consistency. Few, if any, attempts have been made to account for the possibility that a response shift may have occurred in the evaluation of HR-QOL. Most studies have compared HR-QOL scores of children with illness with their healthy peers. As such, there is a dearth of knowledge regarding the normative process of adaptation within the context of illness. It is recommended that researchers focus on gathering data using a relative standard of comparison. We further recommend that researchers interpret HR-QOL data in line with their intended purpose. Regarding developmental consideration, particular attention ought to be paid to developing instruments that consider children's emerging sense of self, cognitive capacity and emotional awareness. Instruments that include items that are age appropriate are more likely to maximise reliability and validity of reports. The results of many HR-QOL instruments are applied in pharmacotherapeutic and pharmacoeconomic assessments. However, there has been relative infrequent application of economically valid HR-QOL tools (utility scales) and the use of HR-QOL scales as outcome measures in paediatric drug trials. As such, few cost-utility analyses have been performed to inform paediatric decision making. In addition, many of the concerns in the development of HR-QOL instruments should also be applied to the utility scales such that they reflect adequately children's preferences for health states.

Abstract
OBJECTIVE To assess the effectiveness of adenotonsillectomy in children with mild symptoms of throat infections or adenotonsillar hypertrophy. DESIGN Open, randomised controlled trial. SETTING 21 general hospitals and three academic centres in the Netherlands. PARTICIPANTS 300 children aged 2-8 years requiring adenotonsillectomy. INTERVENTION Adenotonsillectomy compared with watchful waiting. MAIN OUTCOME MEASURES Episodes of fever, throat infections, upper respiratory tract infections, and health related quality of life. RESULTS During the median follow up period of 22 months, children in the adenotonsillectomy group had 2.97 episodes of fever per person year compared with 3.18 in the watchful waiting group (difference -0.21, 95% confidence interval -0.54 to 0.12), 0.56 throat infections per person year compared with 0.77 (-0.21, -0.36 to -0.06), and 5.47 upper respiratory tract infections per person year compared with 6.00 (-0.53, -0.97 to -0.08). No clinically relevant differences were found for health related quality of life. Adenotonsillectomy was more effective in children with a history of three to six throat infections than in those with none to two. 12 children had complications related to surgery. CONCLUSION Adenotonsillectomy has no major clinical benefits over watchful waiting in children with mild symptoms of throat infections or adenotonsillar hypertrophy.

Abstract
BACKGROUND Reduction of the treatment-related side effects has become one of the main goals of the recent study protocols for brain tumor therapies. When the treatment burden is decreased in patients with good prognostic features, the potential increased risk of relapse has to be counterbalanced by a significantly improved cognitive outcome. This objective is always clearly stated but comprehensive data on the neuropsychological outcomes are seldom reported. PROCEDURES AND RESULTS The appropriate means to measure the long-term morbidity need to be clarified. Health Status and Quality of Life (QOL) questionnaires can be easily administered but these questionnaires represent usually a composite evaluation where cognition is analyzed along with other items such as mood or pain. However, none of these questionnaires has ever been used to measure a difference in cognitive outcome when comparing two different therapeutic strategies in children. Complete neuropsychological evaluations are time consuming, need specialized psychologists and most of the tests have not been rigourously validated. In this respect, Wechsler scales are, however, robust and objective methods to evaluate intelligence. Several studies have been able to show meaningful differences in IQ scores between treatments in children with posterior fossa tumors, even with small numbers of patients. CONCLUSIONS In order to evaluate any refinement in the treatment of these patients, widely accepted evaluation tools are needed. Ideally, these methods will have to be sensitive, reproducible, and widely applicable. None of the available tools fullfil all of these criteria but their development should be a major endeavour in modern neuro-oncology.

Abstract
OBJECTIVE To develop and evaluate a parent-completed questionnaire for use by clinicians as part of routine care to assess the burden of diurnal and nocturnal enuresis on children and their families. METHODS The questionnaire consisted of items that measure the impact on the child and his/her parent, the child's coping ability and commitment to treatment, previous treatment success, family frustration and overall cohesion, and parental attitudes about enuresis and its treatment. Questionnaires (n = 208) were completed by parents during the child's scheduled office visit for enuresis at 5 specialty clinics across the United States. Traditional criteria were used to assess reliability and validity of the questionnaire, including analysis of variance. RESULTS Success rates provide evidence that many of the items in the child scale (79%) and all items in the parent scale (100%) met stringent criteria. alpha values were.62 and.77, respectively. Statistically significant differences were observed for the scales across responses on all but 1 global item, the majority of parental attitude items, whether the child urinated at bedtime, and the number of pads used. These findings suggest that the child's coping ability and commitment and the family's overall cohesion and frustration with the problem influence parental perceptions about the impact of enuresis on the child and the family. CONCLUSIONS Findings about the performance of the new measure were satisfactory and suggest that, after further refinement, it should prove as a useful tool for clinicians treating enuresis in children.

Abstract
Neighbourhood objective socio-economic indicators and community-reported subjective measures of social capital were examined in relation to children's health-related quality of life in the Netherlands. Three different data-sources were used: (1) objective neighbourhood socio-economic indicators, (2) subjective neighbourhood data on social capital, and (3) individual data of a family cohort study, including questions on children's health-related quality of life, and family socio-economic status. Multilevel analyses were conducted using both neighbourhood level and individual level data. Neighbourhood socio-economic status and social capital were associated. Measures of socio-economic deprivation and social capital were both non-specifically associated with children's general health and satisfaction, independent of possible individual-level confounders. However, children's mental health and behaviour were specifically associated with one aspect of social capital, the degree of informal social control in the neighbourhood.

Abstract
Von Willebrand disease (VWD) is the commonest inherited disorder of hemostasis and the majority of women with this disorder experience excessive uterine bleeding. Yet very little information is available on the health-related quality of life (HRQL) in individuals with VWD. To test the a priori hypotheses that these individuals will have poorer HRQL than members of the general population, and that this burden of morbidity will correlate with the severity of VWD, a cross-sectional study was undertaken of a population-based cohort in a regional hemophilia program in Ontario, Canada. A survey was made of individuals over 13 years of age with VWD who self-reported their health status using a standard 15 item questionnaire. The responses were converted to levels in the Health Utilities Index Mark 2 (HUI2) and Mark 3 (HUI3) health status classification systems to form multi-element vectors from which single attribute morbidity and overall HRQL utility scores were determined. As a group, individuals with VWD were shown to have poorer HRQL than members of the general population and those with Type 2 disease carried a greater burden of overall morbidity than those with Type 1 disorder. Morbidity was evident mainly in the attributes of emotion, cognition with pain. A striking difference was observed between males and females, with the latter having overall HRQL utility scores similar to those reported previously for HIV positive, severe hemophiliacs. It is possible that this remarkable burden of morbidity reflects chronic iron deficiency associated with menorrhagia. A national study has been proposed to address this likelihood as it offers an opportunity for effective therapeutic intervention (iron supplementation) with a concomitant gain in health status and HRQL.

Abstract
PURPOSE OF REVIEW To review the results from recent studies that assessed the burden of allergic diseases on the patients' every-day life, or contributed to new advances in monitoring quality-of-life in allergic disorders. This review will not report the numerous clinical trials that included quality-of-life as an outcome. RECENT FINDINGS Quality-of-life impairment was investigated in patients with asthma, allergic rhinitis, atopic dermatitis or food allergy. A new questionnaire was validated for patients with yellow jacket allergy. At the same time, the properties of formerly developed questionnaires were further investigated and tools were developed to assess factors related to quality-of-life, such as work functioning, or perceived control of the disease. SUMMARY Allergic disorders are associated with a variety of limitations in the patients' daily life. The relative burden of concomitant disorders, however, has not been thoroughly investigated. When monitoring quality-of-life, investigators should ensure that the results are not biased by confounding factors that may affect quality-of-life. Moreover, the uncertainty around estimates of change in health status related to treatment and around standard thresholds for clinical significance should be taken into account before drawing inference as regards the treatment worthiness.

Abstract
The aim of the study was to evaluate the psychometric properties of the German translation of the Child Health Questionnaire (CHQ). Parents of two clinical samples were asked to rate the quality of life of their children using the German version of the CHQ. Item internal consistency (item-scale correlation) and internal consistency of scales were tested; quartiles and factor analysis were conducted. The results of the German clinical samples were compared with US clinical samples (t-test). The two clinical German sub-groups were compared using multivariate analysis (MANOVA). The psychometric testing of the CHQ showed good results. Internal consistency of the hypothesized scales were all higher than 0.70. The results of the factor analysis confirmed the results of the US norm sample: As expected, the subscales loaded on two factors explaining 57.4% of the total variance. The group comparison supported the discriminative properties of the CHQ. Preliminary psychometric findings support use of the German version of the CHQ. The next step will be the testing of healthy German samples and development of norm scores.

Abstract
The objective of this study was to evaluate the construct validity of two questionnaire-based measures of health-related quality of life (HRQL) in children undergoing cancer chemotherapy: the Health Utilities Index (HUI) and the Child Health Questionnaire (CHQ). Subjects were children hospitalised for chemotherapy. To examine construct validity: (1). a priori expected relations between CHQ concepts and HUI attributes were examined; (2). HUI and CHQ summary scores were compared to visual analogue scale (VAS) scores. Ease of completion was rated using a 5-point categorical scale and completion time was recorded. A total of 36 subjects were included. The maximum score was seen in 15 (47%) of HUI3 assessments. As predicted, CHQ body pain was moderately correlated with HUI3 pain (r=0.51), CHQ physical functioning was moderately correlated with HUI2 mobility (r=0.58) and CHQ mental health was moderately correlated with HUI2 emotion (r=0.53). Only the CHQ psychosocial subscale (and not HUI) was correlated with VAS (r=0.44). The CHQ and the HUI were both easy to use. The HUI questionnaires required less time to complete (mean=3.1, s.d.=1 min) compared with CHQ (mean=13.1, s.d.=3.4 min, P<0.0001). In conclusion, HUI and CHQ demonstrated construct validity in children undergoing cancer chemotherapy. The Health Utilities Index is subject to a ceiling effect whereas CHQ requires more time to complete.

Abstract
The goals of the present study were (1) to measure health-related quality of life (HRQOL) in pediatric liver transplantation (LT), (2) to identify demographic and clinical factors that correlate with HRQOL, and (3) to compare two instruments that have been used to measure HRQOL in children and adolescents. We conducted a single-center cross-sectional study of 77 pediatric LT recipients ages 5 to 18 years, all of whom had had LT at least 6 months previously. We used the Child Health Questionnaire Parent Form 50 (CHQPF50) and the PedsQL4.0 to determine measured dimensions of physical and psychosocial health from the parents' perspective. Individual scale scores range from 0 to 100, with higher scores reflecting better health. Data on demographics, clinical status at transplantation, posttransplantation clinical course, and graft function were collected to identify predictors of posttransplantation HRQOL. Fifty-three percent of the liver transplant recipients had biliary atresia, 78% were white, and 61% were female. The mean age at LT was 3.8 +/- 3.6 years, and the range of time since LT was 1 to 15 years. HRQOL in pediatric liver transplant recipients was lower than that reported for healthy children but similar to that for children with other chronic illness. Age at transplantation, the time elapsed since transplantation, hospitalizations within the previous year, maternal education, and race were significant predictors of physical health. Age at transplantation and maternal education predicted psychosocial function. HRQOL was decreased in a population of pediatric liver transplant recipients compared with the general population and similar to that for children with chronic illness. Prospective longitudinal studies will permit us to define predictors of HRQOL at different periods of time after transplantation. The information gained from this study will help us to better define expectations and the clinical course after liver transplantation to patients and their families.

Abstract
UNLABELLED Feasibility, reliability, and discriminative validity of the cross-culturally adapted Dutch version of the originally US child health questionnaire-child form (CHQ-CF87), an 87-item generic pediatric health-related quality of life instrument, were assessed. The success criterion in this first evaluation was the equivalence of psychometric properties of the adapted and the original CHQ. A total of 466 schoolchildren (9-17 years) were invited to complete the questionnaire in the classroom. Test-retest reliability was measured after 14 days in a subgroup (n = 71). Response was 96%. Four scales had ceiling effects (>50%), as was reported in an Australian study. Cronbach alpha-values were adequate (>0.70), except for 'physical functioning' (0.56). Test-retest correlations, not previously reported, were not statistically significant for two CHQ-scales, whereas average retest scores indicated better health for five scales (p < 0.01). The CHQ scales discriminated significantly (p < 0.01) between children without (n = 281) and children with two or more self-reported chronic diseases (n = 59). This is in correspondence with US and Australian reports. CONCLUSIONS The current data support application of the Dutch CHQ-CF in predominantly healthy populations, e.g. in school settings. Given the limitations of this study and some less favorable results (score distributions, internal consistency, test-retest reliability), further evaluation of the CHQ-CF is recommended, preferably by analyses of item performance and scale validity in international data sets that include varied clinical subgroups.

Abstract
Health status results from an individual's values placed on the interactions among a person's physical state, associated mental perceptions and emotions, resulting behaviors, and environment. Improving health-related quality of life is the goal of all disease treatment. This article reviews the components of health status, summarizes relevant studies in children with rheumatic and related diseases, and considers the role that future studies will play in improving care for children with rheumatic diseases.
