Purpose: To describe the development of pediatric family relationships measures, with versions for child self-report (8-17 years) and parent-report for children 5-17 years old. Measures were created for integration into the Patient Reported Outcomes Measurement Information System (PROMIS®).Methods: Semi-structured interviews with 10 experts, 24 children, and 8 parents were conducted to elicit and clarify essential elements of family relationships. A systematic literature review was conducted to identify item concepts representative of each element. The concepts were transformed into items that were iteratively revised based on cognitive interviews (n = 43 children) and item translatability review. Psychometric studies involving 2846 children and 2262 parents were conducted to further refine and validate the instruments.Results: Qualitative procedures supported the development of content valid Family Relationships item banks. Final child- and parent-report item banks each contain 47 items. Unidimensional item banks were calibrated using IRT-modeling to estimate item parameters representative of the US population and to enable computerized adaptive test administration. Four- and eight-item short forms were constructed for standard fixed format administration. All instruments have strong internal consistency, retest-reliability, and provide precise estimates of various levels of family relationship quality. Preliminary evidence of the instruments' validity was provided by known-group comparisons and convergence with legacy measures.Conclusion: The PROMIS pediatric Family Relationships measures can be applied in research focused on determinants, outcomes, and the protective effects of children's subjective family relationship experiences.

Purpose: To derive and evaluate a shorter self-report Child Health Questionnaire (CHQ) legacy measure for use in research and clinical trials/care.Methods: Stepwise regression, factor analysis, and item scaling principles were used to derive and guide item selection, using data from a large general sample in the Netherlands (n = 933). Feasibility was assessed in a school sample (n = 114) and item internal consistency, discriminant validity, floor, and ceiling effects were evaluated using an external larger validation sample in the US (n = 1468). Reliabilities were estimated using Cronbach's alpha. Relative precision (RP), the ability to distinguish between clinical subgroups, was computed by comparing the proportion of variance explained by the short-form scales vs. respective full-length scales.Results: The CHQ-CF was reduced from 87 to 45 items. The median alpha coefficient was 0.89. Ninety-seven to 100% scaling successes for item discriminant validity were observed. Floor effects were not observed; some ceiling effects were detected. RP estimates ranged from 0.73 to 1.37.Conclusion: The CHQ-SF45 is reliable and valid and exceeds item level scaling criteria. [ABSTRACT FROM AUTHOR]

Objective Evaluate the feasibility and psychometric properties of the Infant Toddler Quality of Life (ITQOL) questionnaire as a measure of health-related quality of life (HRQOL) in a sample of Chinese infants. Methods The linguistically validated Simplified Chinese version of the ITQOL was used in a multicenter, observational study of healthy, term infants (N = 427), age 6 weeks at enrollment, in China. At Days 1 and 48, parents/guardians completed the ITQOL, the Short Form Health Survey (SF-12v2) and the Infant Gastrointestinal Symptom Questionnaire (IGSQ). ITQOL feasibility, reliability, ceiling/floor effects, concurrent validity and discriminatory validity were evaluated. Results Feasibility of administering the ITQOL was supported by strong response rates (> 97%) with < 1% missing items for all scales except physical abilities. Reliability was acceptable (Cronbach’s alpha > 0.70) for all scales except Day 1 General Health (0.67). Floor effects were minimal (< 2%), except Day 1 physical abilities (7%). Ceiling effects increased from Days 1 to 48 across all scales. Concurrent validity was demonstrated by correlations between ITQOL infant-focused scales and IGSQ score (r = −0.20 to − 0.34, p < 0.001) and between parent-focused scales and SF-12v2 mental health composite (MCS) scores (r = 0.29-0.46, p < 0.001). ITQOL scales discriminated between infant subgroups based on illness-related outcomes (sick visits, adverse events) and between parent subgroups based on SF-12v2 MCS scores. Conclusion The Simplified Chinese version of the ITQOL performed well in a community-based sample of Chinese infants, with evidence supporting the instrument’s feasibility, reliability, and validity. These data support the ITQOL as a valuable tool to assess HRQOL in Chinese infants. [ABSTRACT FROM AUTHOR]

The objective of this study was to assess the impact of health-related quality of life (HRQOL) across prevalent chronic conditions, individually and comorbid, in school-aged children in the Netherlands. 5301 children aged 4–11 years from the Dutch Health Interview Survey were included. Parents completed questionnaires regarding child and parental characteristics. HRQOL of children was measured using the Child Health Questionnaire Parent Form 28 (CHQ-PF28). Independent-t tests were used to assess differences in the mean scores of the CHQ-PF28 summary scales and profile scales between children with a prevalent chronic condition (excluding or including children with multiple chronic conditions) and children without a chronic condition. Cohen’s effect sizes (d) were calculated to assess the clinical significance of difference. The mean age of children was 7.55 (SD 2.30) years; 50.0% were boys. In children without any chronic condition, the mean score of physical summary scale (PhS) was 58.53 (SD 4.28) and mean score of the psychosocial summary scale (PsS) was 53.86 (SD 5.87). Generally, PhS and/or PsS scores in children with only one condition were lower (p<0.05) than for children without chronic conditions. When children with multiple conditions were included, mean scores of CHQ-PF28 summary and profile scales were generally lower than when they were excluded. The present study shows important information regarding the impact of prevalent chronic conditions on HRQOL in a representative population-based sample of school-aged children in the Netherlands. The information could be used for developing a more holistic approach to patient care and a surveillance framework for health promotion. [ABSTRACT FROM AUTHOR]

Background: Health related quality of life is the functional effect of a medical condition and/or its therapy upon a patient, and as such is particularly suitable for describing the general health of children. The objective of this study was to identify and confirm potential determinants of health-related quality of life in children aged 4-11 years in the general population in the Netherlands. Understanding such determinants may provide insights into more targeted public health policy. Methods: As part of a population based cross sectional study, the Child Health Questionnaire (CHQ) Parental Form 28 was used to measure health-related quality of life in school-aged children in a general population sample. Parents of 10,651 children aged 4-11 years were interviewed from January 2001 to December 2009. Results: Multivariate and regression analyses demonstrated a declined CHQ Physical Summary score for children who had >1 conditions, disorders or acute health complaints and who were greater consumers of healthcare; children with a non-western immigrant background; and children whose parents did not work. Lower CHQ Psychosocial Summary score was reported for children who had >1 conditions, disorders or acute health complaints, boys, children of single parents and obese children. Conclusion: The best predictors of health-related quality of life are variables that describe use of health care and the number of disorders and health complaints. Nonetheless, a number of demographic, socio-economic and family/environmental determinants contribute to a child’s health-related quality of life as well. [ABSTRACT FROM AUTHOR]

Purpose: The present study investigated the higher-order summary factor structure of the Child Health Questionnaire Parent Form-50 (CHQ) in a sample of children with new-onset epilepsy. The secondary aim was to identify risk factors predicting health-related quality of life (HRQL) 24 months post-diagnosis. Methods: Data came from the Health-related Quality of Life in Children with Epilepsy Study (HERQULES, N = 374), a multi-site study documenting HRQL among children with epilepsy from diagnosis through 24 months. Confirmatory factor analysis was used to determine goodness of fit between the original structure of the CHQ and HERQULES data. Multiple regression was used to identify risk factors at diagnosis for HRQL at 24 months. Results: The models demonstrated good fit: baseline: CFI = 0.945; TLI = 0.941; WRMR = 1.461; RMSEA = 0.058; 24 months: CFI = 0.957; TLI = 0.954; WRMR = 1.393; RMSEA = 0.055. Factor loadings were high and no cross-loadings observed (first order: λ = 0.27–0.99, 0.24–0.98; second order: λ = 0.69–0.86, 0.54–0.92; p < 0.001 for all). Controlling for HRQL at diagnosis, predictors for better 24-month HRQL were as follows: physical health: fewer cognitive problems ( p = 0.023) and parents with fewer depressive symptoms ( p = 0.049); psychosocial health: older parent age ( p = 0.043), fewer behavior problems ( p = 0.004), and families with better functioning ( p = 0.008) and fewer demands ( p = 0.009). Conclusions: The CHQ higher-order summary factor structure was replicated in a sample of children with new-onset epilepsy, and child and family risk factors at diagnosis were found to predict HRQL 24 months post-diagnosis. These findings suggest it is possible to identify at-risk children early in the illness process and provide impetus for adopting family-centered care practices. [ABSTRACT FROM AUTHOR]

Purpose: Examine the health-related quality of life of 5-6-year-old underweight, overweight and obese children. Methods: Our cross-sectional study included 3,227 parent-child dyads from the 'Be active, eat right' study. Parents completed questionnaires regarding child and parental characteristics. Health-related quality of life of the child was measured using the Child Health Questionnaire Parent Form 28. Children were classified normal weight, overweight, obese, severely obese, and underweight according to the international age and gender BMI cutoff points. Bootstrap analyses were performed for general linear models corrected for potential confounding variables. Results: Severely obese children (β, −2.60; 95 % CI, −4.80 to −0.57, p < 0.01) and underweight children (β, −1.11; 95 % CI, −1.85 to −0.39, p < 0.01) had lower parent-reported scores on the physical summary scale. On the physical functioning profile scale parents of overweight and severely obese children also reported statistically significant lower scores ( p < 0.05 and p < 0.01, respectively).There were no significant differences regarding the psychosocial summary scale scores between the different weight categories. Conclusion: Underweight and overweight children experience impaired health-related quality of life on the physical functioning domain. Physicians, teachers and parents should be aware of the possible negative impact on health-related quality of life in underweight and overweight 5-6-year-old children. [ABSTRACT FROM AUTHOR]

Purpose: To derive and evaluate a shorter infant/toddler quality of life questionnaire (ITQOL) for use in clinical care. Methods: Stepwise regression, factor analysis, and item-scaling principles were used to derive and guide item selection using data from a large general sample in the Netherlands ( n = 5,211) and a 'wheezing illness' sample ( n = 138). Item internal consistency, discriminant validity, and floor and ceiling effects were evaluated using a general Dutch sample (Salland Region n = 410) and two clinical samples: Functional abdominal pain (FAP, n = 81) and Burn ( n = 194). Reliabilities were estimated using Cronbach's alpha. Relative precision (RP), the ability to distinguish between clinical subgroups, was computed by comparing the proportion of variance explained by the short-form scales versus respective full-length scales. Results: The ITQOL was reduced from 97 to 47 items. Median alpha coefficients were 0.77 Salland sample, 0.76 (FAP), and 0.84 (Burn). Ninety-one to 100 % scaling successes for item discriminant validity were observed for 21 of 24 tests (8 scales, 3 samples). Floor effects were not observed; some ceiling effects were detected. RP estimates in the Salland sample ranged from 2.40 (physical abilities) to 0.58 (temperament and moods). RP estimates in the FAP sample were 0.85 (bodily pain), 1.36 (temperament and moods) and 1.62 (parental-impact emotional) and for Burn, 1.51 (temperament and moods) and 0.59 (general health perceptions). Conclusion: The ITQOL-SF47 is reliable and valid and exceeds item-level scaling criteria. [ABSTRACT FROM AUTHOR]

Purpose: To assess whether the health-related quality of life of infants from ethnic minority groups differs from the health-related quality of life of native Dutch infants and to evaluate whether infant health and family characteristics explain the potential differences. Methods: We included 4,506 infants participating in the Generation R Study, a longitudinal birth cohort. When the child was 12 months, parents completed the Infant Toddler Quality of Life Questionnaire (ITQOL); ITQOL scale scores in each ethnic subgroup were compared with scores in the Dutch reference population. Influence of infant health and family characteristics on ITQOL scale scores were evaluated using multivariate regression models. Results: Infants from ethnic minority groups presented significantly lower ITQOL scale scores compared to the Dutch subgroup (e.g., Temperament and Moods scale: median score of Turkish subgroup, 70.8 (IQR, 15.3); median score of Dutch subgroup, 80.6 (IQR, 13.9; P < 0.001)). Infant health and family characteristics mediated an important part of the association between the ethnic minority status and infant health-related quality of life. However, these factors could not fully explain all the differences in the ITQOL scale scores. Conclusions: Parent-reported health-related quality of life is lower in infants from ethnic minority groups compared to native Dutch infants, which could partly be explained by infant health and by family characteristics.

Purpose: This study compares HRQOL among subgroups of infants with asthma-like symptoms to a subgroup without such symptoms and examines independent associations between asthma-like symptoms during the first year of life and HRQOL at age 12 months.Methods: Our study sample included 5,000 infants participating in the Generation R study. Their parents completed structured questionnaires to obtain information on asthma-like symptoms, HRQOL, infants', and maternal characteristics. Asthma-like symptoms were defined according to the number of positive answers to 12 items on lower respiratory symptoms. HRQOL was measured using the ITQOL. Higher scores indicated better HRQOL.Results: Infants with asthma-like symptoms had significantly lower HRQOL scores for all ITQOL scales. Among the subgroup with severe symptoms (4% of the infants), relevant deficits in HRQOL were observed for most ITQOL scales, particularly for General Health, Bodily Pain, and Family Activities (effect sizes ≥ 0.8). In multivariate linear models, asthma-like symptoms were independently associated with 6 ITQOL scales. The population attributable risks were especially high for Family Activities, General Health, Parental Emotional, and Parental Time.Conclusions: Asthma-like symptoms during the first year of life are associated with impaired quality of life at age 12 months. At population level, asthma-like symptoms were associated with lower HRQOL, regardless of symptom severity. [ABSTRACT FROM AUTHOR]

im: The aim of this paper is to describe the Generation R study as a template that enables candidate gene study and genome-wide association study regarding health-related quality of life (HRQOL) of mothers and their young children. Methods: Generation R is a population-based prospective cohort study from fetal life onwards in Rotterdam, The Netherlands. Children were born in 2002-2006. Blood from mothers and placenta cord blood were sampled. Mothers' HRQOL was measured 5 times during pregnancy and after birth using SF-12 and EQ-5D. Children's HRQOL was measured 5 times between age 1 and 5/6 years using Infant-Toddler Quality Of Life questionnaire (ITQOL), Health Status Classification System PreSchool (HSCS-PS) and Child Health Questionnaire Parent Form 28 items (CHQ-PF28), respectively. Results: DNA is available for 8,055 mothers and 5,908 children. Genotyping of various candidate genes and a genome-wide association (GWA) scan (Illumina 610K) of child DNA were done. A template for gene-HRQOL analyses is provided. We start with candidate gene study on HRQOL of mothers and children. Gene-environment interaction and interaction with medical indicators of health status will be explored. Next, GWA study on HRQOL will be performed. Conclusions: Gaining insight into the determinants of HRQOL is essential to assisting efforts in health policy and clinical application to improve well-being and health. In the future, it might be possible to complement HRQOL assessments by examinations of genetic markers. Strengths and weaknesses of the Generation R study are discussed. [ABSTRACT FROM AUTHOR]

This is the first study to evaluate ADHD hyperactive/ impulsive subtype in a large clinical sample of adults with ADHD. The Quality of Life, Effectiveness, Safety and Tolerability (QuEST) study included 725 adults who received clinician diagnoses of any ADHD subtype. Cross-sectional baseline data from 691 patients diagnosed with the hyperactive/impulsive (HI), inattentive (IA) and combined subtypes were used to compare the groups on the clinician administered ADHD-RS, clinical features and health-related quality of life. A consistent pattern of differences was found between the ADHD-I and combined subtypes, with the combined subtype being more likely to be diagnosed in childhood, more severe symptom severity and lower HRQL. Twenty-three patients out of the total sample of 691 patients (3%) received a clinician diagnosis of ADHD - hyperactive/impulsive subtype. Review of the ratings on the ADHD-RS-IV demonstrated, however, that this group had ratings of inattention comparable to the inattentive group. There were no significant differences found between the ADHD-HI and the other subtypes in symptom severity, functioning or quality of life. The hyperactive/impulsive subtype group identified by clinicians in this study was not significantly different from the rest of the sample. By contrast, significant differences were found between the inattentive and combined types. This suggests that in adults, hyperactive hyperactivity declines and inattention remains significant, making the hyperactive/impulsive subtype as defined by childhood criteria a very rare condition and raising questions as to the validity of the HI subtype in adults.

Objective: This prospective study evaluated the reliability and validity of the Infant and Toddler Child Quality of Life Questionnaire (ITQOL) by comparing quality of life (QOL) of two groups of children afflicted with early childhood dental caries with a caries-free group. Methods: A convenience sample of 150 children divided into three groups (mean age [months] 51 ± 15) was studied. Group I (OR) had extensive dental caries and were waiting for several months for treatment under general anesthesia. Group II were children who sought emergency services for acute odontogenic pain/abscess, and group III were children who were caries-free new patients. Parents/caretakers were administered the ITQOL, which assesses a child’s physical, emotional and social well being from the parent/guardian’s perspective. Results: The ITQOL had high success in item validity with good reliability. Significant differences in QOL were noted for scales of pain and discomfort, behavior and moods, global behavior, and impact on parental time ( P ≤ 0.05) among the three groups. No significant differences were noted for scales of growth and development, general health and impact on parents’ emotional and mental health. Conclusions: The ITQOL proved to be a useful instrument for characterizing QOL in this dental caries-afflicted sample. Overall, children with chronic and acute dental caries had a poorer QOL than caries-free children in areas of behavior, mood, pain and parental impact. [ABSTRACT FROM AUTHOR]

In this study we evaluated indicators of the feasibility, reliability, and validity of the Child Health Questionnaire-Child Form (CHQ-CF). We compared the results in a subgroup of adolescents who completed the standard paper version of the CHQ-CF with the results in another subgroup of adolescents who completed an internet version, i.e., an online, web-based CHQ-CF questionnaire. Under supervision at school, 1,071 adolescents were randomized to complete the CHQ-CF and items on chronic conditions by a paper questionnaire or by an internet administered questionnaire. The participation rate was 87%; age range 13–17 years. The internet administration resulted in fewer missing answers. All but one multi-item scale showed internal consistency reliability (Cronbach’s α > 0.70). All scales clearly discriminated between adolescents with no, a few, or many self-reported chronic conditions. The paper administration resulted in statistically significant, higher scores on 4 of 10 CHQ-CF scales compared with the internet administration ( P < 0.05), but Cohen’s effect sizes d were ≤ 0.21. Mode of administration interacted significantly with age ( P < 0.05) on four CHQ-CF scales, but Cohen’s effect sizes for these differences were also ≤ 0.21. This study supports the feasibility, internal consistency reliability of the scales, and construct validity of the CHQ-CF administered by either a paper questionnaire or online questionnaire. Given Cohen’s suggested guidelines for the interpretation of effect sizes, i.e., 0.20–0.50 indicates a small effect, differences in CHQ-CF scale scores between paper and internet administration can be considered as negligible or small.

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). 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– $${5\frac{1}{2}}$$ years old; n = 217) were mailed ITQOL and TAPQOL questionnaires; a retest was sent after two weeks. Feasibility: The response was ≥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 α >0.70. Test–retest Intraclass Correlation Coefficients (ICCs) were moderate or adequate (≥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). 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 FROM AUTHOR]

Objective To assess the functional and behavioral health of unaccompanied Sudanese refugee minors approximately 1 year after resettlement in the United States. Design A descriptive survey. Setting Local refugee foster care programs affiliated with the US Unaccompanied Refugee Minors Program. Participants A total of 304 Sudanese refugee minors enrolled in the US Unaccompanied Refugee Minors Program. Main Outcome Measures Health outcomes were assessed using the Harvard Trauma Questionnaire and the Child Health Questionnaire. Outcomes included the diagnosis of posttraumatic stress disorder and scores on all Child Health Questionnaire subscales and global single-item assessments. Results Twenty percent of the minors had a diagnosis of posttraumatic stress disorder and were more likely to have lower (worse) scores on all the Child Health Questionnaire subscales. Low functional and behavioral health scores were seen mainly in functioning in the home and in subjective health ratings. Social isolation and history of personal injury were associated with posttraumatic stress disorder. Conclusions Unaccompanied Sudanese minors have done well in general. The minors function well in school and in activities; however, behavioral and emotional problems manifest in their home lives and emotional states. The subset of children with traumatic symptoms had characteristics that may distinguish them from their peers and that may inform future resettlement services for unaccompanied minors in the United States.

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 α>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.

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 FROM AUTHOR]

Background: Few measures of health related quality of life exist for use with preschool aged children. The objective of this study was to assess reliability and validity of a new multidimensional generic measure of health-related quality of life developed for use with preschool children. Methods: Cross-sectional survey sent to parents as their child turned 3 1/2 years of age. The setting was the province of British Columbia, Canada. Patients included all babies admitted to tertiary level neonatal intensive care units (NICU) at birth over a 16-month period, and a consecutive sample of healthy babies. The main outcome measure was a new full-length questionnaire consisting of 3 global items and 10 multi-item scales constructed to measure the physical and emotional well-being of toddlers and their families. Results: The response rate was 67.9%. 91% (NICU) and 84% (healthy baby) of items correlated with their own domain above the recommended standard (0.40). 97% (NICU) and 87% (healthy baby) of items correlated more highly (.≥ S.E.) with their hypothesized scale than with other scales. Cronbach's alpha coefficients varied between .80 and .96. Intra-class correlation coefficients were above .70. Correlations between scales in the new measure and other instruments were moderate to large, and were stronger than between non-related domains. Statistically significant differences in scale scores were observed between the NICU and healthy baby samples, as well as between those diagnosed with a health problem requiring medical attention in the past year versus those with no health problems. Conclusions: Preliminary results indicate the new measure demonstrates acceptable reliability and construct validity in a sample of children requiring NICU care and a sample of healthy children. However, further development work is warranted. [ABSTRACT FROM AUTHOR]

Objective: To psychometrically evaluate a new parent-completed questionnaire that measures the effect of attention-deficit/hyperactivity disorder (ADHD) on the everyday well-being of children and their families. Setting: Using a mail-out/mail-back method, the sample was drawn from the registry of an outpatient developmental and behavioral program of a large tertiary pediatric hospital. All children received medication for ADHD. Participants: Responses were received for 81 children of whom 60 (74%) were boys. An even split of questionnaires was returned for children with ADHD primarily inattentive (50%) and ADHD combined (50%). The condition of 70 patients (86%) had been diagnosed for 1 year or longer; 69 patients (89%) reported receiving medication. Main Outcome Measure: The ADHD Impact Module, HealthAct, Boston, Mass, developed with input from families, measures the effect of the disorder on the child's emotional–social well-being (Child Scale, 8 items) and the family (Home Scale, 10 items). Results: The scales exceeded standard criteria for item convergent and discriminant validity. No floor effects and minimal (2%) ceiling effects were observed. Cronbach α was 0.88 and 0.93 (Child and Home Scales), respectively. Raw scale scores are transformed on a 0 through 100 continuum; a higher score indicates more favorable findings. Statistically significant differences (P<.000) were observed for ADHD inattentive vs ADHD combined on both scales (Child, 65.26 vs 48.86; Home, 72.79 vs 51.26). Better "success at home" scores were reported by parents of ADHD inattentive children (Child Scale, 62.12 vs 47.36, P = .00; Home Scale, 70.58 vs 47.01, P = .000). Conclusions: The ADHD Impact Module meets stringent psychometric standards. Further validation is required, but current evidence suggests it is a promising new questionnaire. [ABSTRACT FROM AUTHOR]

Objectives: To report and quantify the health-related quality of life of children who require surgical intervention for chronic recurrent rhinosinusitis and to assess the perspective of the child vs that of the parent. Design: Prospective, observational. Patients and Intervention: Twenty-one of a consecutive sample of 35 children undergoing endoscopic sinus surgery for infectious indications completed, along with their parents, the Child Health Questionnaire. The Child Health Questionnaire measures in parallel both child and parent perceptions of health by means of separate parent proxy report (Child Health Questionnaire-Parent Form 50) and child self-report (Child Health Questionnaire-Child Form 87) questionnaires concerning physical and psychosocial functioning. Main Outcome Measures: Tabulated scores from both the Child Health Questionnaire-Parent Form 50 and Child Health Questionnaire-Child Form 87 were compared with published data from age-matched normative populations and several pediatric chronic disease groups. Results: Significant decrements in the general health of children with chronic recurrent rhinosinusitis compared with a normative sample were observed for both child- and parent-reported data, particularly in the physical domains. Children with rhinosinusitis were perceived by their parents to have significantly more bodily pain (P<.001)and to be more limited in their physical activities (P<.05)than children with asthma, juvenile rheumatoid arthritis, and other chronic disorders. Parent-child perceptions did vary, with parents reporting more pain and general behavioral effects relative to their children's reports in these areas. Conclusion: The health impact of chronic recurrent rhinosinusitis as reported by the subjective evaluations of pediatric patients and their parents is severe. [ABSTRACT FROM AUTHOR]
