Project description:Half of children admitted after surgery experience intense pain in hospital, and many experience continued pain and delayed functional recovery at home. However, there is a gap in tools available to measure acute functional ability in pediatric postsurgical settings. We aimed to validate the Youth Acute Pain Functional Ability Questionnaire (YAPFAQ) in a large inpatient pediatric surgical population, evaluate its responsiveness to expected functional recovery, and develop a short form for broad clinical implementation. The YAPFAQ is a self-report measure assessing acute functional ability, developed in children admitted for acute sickle cell pain. We evaluated psychometric properties of the measure in 564 children ages 8 to 18 years admitted after surgery. A sample of 54 participants completed the YAPFAQ daily for 3 days after major surgery to assess responsiveness. The measure showed good reliability (Cronbach ? = .96) and construct validity, with expected relationships with physical health-related quality of life (r = -.53, P < .001) and pain intensity (r = .42, P < .001). YAPFAQ scores decreased over time showing good responsiveness to expected recovery. A 3-item short form of the YAPFAQ showed promising psychometric properties. Early assessment of functioning after surgery may identify children at risk for poor functional outcomes and allow targeting of therapies to improve postsurgical recovery. PERSPECTIVE:The YAPFAQ showed promising psychometric properties in a pediatric postsurgical population. This study addresses a gap in tools available to monitor functional recovery during hospitalization after pediatric surgery. Early detection of problems with recovery may enable targeted therapies to improve postsurgical outcomes.

Project description:ObjectiveTo design and validate a literature-derived, population-based Children's Dietary Inflammatory Index (C-DII)TM.DesignThe C-DII was developed based on a review of literature through 2010. Dietary data obtained from children in 16 different countries were used to create a reference database for computing C-DII scores based on consumption of macronutrients, vitamins, minerals, and whole foods. Construct validation was performed using quantile regression to assess the association between C-reactive protein (CRP) concentrations and C-DII scores.Data sourcesAll data used for construct validation were obtained from children between six and 14 years of age (n = 3300) who participated in the U.S. National Health and Nutrition Examination Survey (NHANES) (2005⁻2010).ResultsThe C-DII was successfully validated with blood CRP concentrations in this heterogeneous sample of 3300 children from NHANES (52% male; 29% African American, 25% Mexican American; mean age 11 years). The final model was adjusted for sex, age, race, asthma, body mass index (BMI), and infections. Children in level 3 (i.e., quartiles 3 and 4 combined) of the C-DII (i.e., children with the most pro-inflammatory diets) had a CRP value 0.097 mg/dL higher than that in level 1 (i.e., quartile 1) for CRP values at the 75th percentile of CRP using quantile regression (p < 0.05).ConclusionThe C-DII predicted blood CRP concentrations among children 6⁻14 years in the NHANES. Further construct validation with CRP and other inflammatory markers is required to deepen understanding of the relationship between the C-DII and markers of inflammation in children.

Project description:IntroductionEating behavior is often established during the first years of life. Therefore, it is important to make a research on it to understand the relationships that children have with food and how this can contribute to prevent the development of childhood obesity. An appropriate assessment of eating behavior can be achieved using the "Child Eating Behavior Questionnaire" (CEBQ). This questionnaire has been validated in several populations and languages, but it has never been translated, adapted, and validated for Spanish children.AimTo evaluate the reliability and internal consistency of the CEBQ questionnaire, culturally adapted and translated into Spanish (Spain), in Spanish families with children aged 3 to 6 years, as well as its association with children's body mass index (BMI) to test its construct validity.Materials and methodsChildren between 3 and 6 years old were recruited from the ongoing MELI-POP randomized controlled clinical trial, as well as from public schools located in middle class neighborhoods of Zaragoza, Spain, to complete the sample. Sociodemographic characteristics and anthropometric measures were obtained according to standardized methods. The 35-item CEBQ questionnaire was completed twice with a time difference of 3 weeks between each response. Statistical analyses included the evaluation of internal consistency and reliability of the questionnaire, a confirmatory factor analysis, and the association between the different CEBQ scales and the children's BMI.ResultsA total of 197 children completed variables; 97 of them were boys (49.2%) and 100 girls (50.8%). Mean age of the total sample was 4.7 ± 0.9 years. There was a high test-re-test reliability of the questionnaire with values close to 1, with an average of 0.66 and a good internal consistency (Cronbach alpha with values above 0.7), so that a high reliability is established between the items in each scale. A gradual positive association was found between the score of different "pro-intake" scales of the CEBQ: "Food Responsiveness," "Emotional Overeating," and "Enjoyment of food" and the children's BMI; at the opposite, negative associations were observed between BMI and the score of anti-intake scales "Satiety Responsiveness," "Slowness in Eating," and "Emotional Undereating."ConclusionThe Spanish version of the CEBQ is a useful tool to assess the eating behavior of Spanish children because the high reliability and internal validity. There is a significant association between eating behavior and BMI in Spanish children.

Project description:The Amblyopia Treatment Index (ATI) is a parental questionnaire that has been used to assess the impact of patching or atropine treatment on the child and family in several amblyopia treatment studies. The 18-item parental questionnaire was designed with versions for treatment with patching or atropine. We pooled data across studies to further evaluate the validity of the ATI, to further assess the presence or absence of factors (subscales).A parent or guardian completed the ATI for 794 children who participated in 1 of 4 randomized clinical trials. Internal consistency reliability was assessed with Cronbach's alpha, and factor analysis was performed.The ATI demonstrated high internal consistency reliability, with a Cronbach's alpha of 0.88 (95% CL = 0.87, 0.89). Factor analysis revealed the same 3 minimally overlapping factors found in the original validation study, which were again labeled "adverse effects," "treatment compliance," and "social stigma." Two of the 18 items did not load with any factor and could reasonably be omitted from future ATI administrations.The ATI is a useful instrument for assessing the impact of patching or atropine treatment on the child and family.

Project description:BACKGROUND:Standard care for HIV clinical practice has started focusing on age-related problems, but despite this recent change physicians involved in HIV care do not often screen HIV patients for frailty. Our aim was to construct three indexes from an HIV clinical database (i.e. Frailty Index, (FI), HIV Index, (HIVI), and Protective Index (PI)) and to assess levels of frailty, HIV severity and demographic and protective lifestyle factors among HIV patients. METHODS AND FINDINGS:We included data from 1612 patients who attended an Italian HIV clinic between September 2016 and December2017 (mean±SD age: 53.1±8 years, 73.9% men).We used 92 routine variables collected by physicians and other health care professionals to construct three indexes: a 72-item FI (biometric, psychiatric, blood test, daily life activities, geriatric syndromes and nutrition data), a 10-item HIVI (immunological, viral and therapeutics) and a 10-item PI (income, education, social engagement, and lifestyle habits data)(the lower the FI and HIVI scores, and the higher the PI scores, the lower the risk for participants).The FI, HIVI and PI scores were 0.19±0.08, 0.48±0.17 and 0.62±0.13, respectively. Men had higher FI (0.19±0.08 vs 0.18±0.08; p = 0.010) and lower HIVI (0.47±0.18 vs 0.50±0.15; p = 0.038) scores than women. FI and HIVI scores both increased 1.9% per year of age (p < 0.001), whereas the PI decreased 0.2% per year (p<0.050). In addition, the FI score increased 1.6% and the PI score decreased 0.5% per year of HIV infection (p < 0.001). CONCLUSION:It is feasible to assess levels of frailty, HIV severity and protective lifestyle factors in HIV patients using data from a clinical database. Frailty levels are high among HIV patients and even higher among older patients and those with a long duration of HIV. Future studies need to examine the ability of the three indices to predict adverse health outcomes such as hospitalization and mortality.

Project description:ObjectiveTo translate and validate the Child Three-Factor Eating Questionnaire (CTFEQr17), assessing cognitive restraint (CR), uncontrolled eating (UE) and emotional eating (EE), among French-speaking Canadian young individuals.DesignPhase 1 comprised a translation and the evaluation of the comprehension of the questionnaire. Phase 2 comprised a confirmatory factor analysis (CFA), the evaluation of internal consistency (Cronbach's α), test-retest reliability (intra-class correlation coefficients (ICC)) and construct validity, including correlations among the CTFEQr17 and Eating Attitudes Test (EAT-26), anthropometrics, dietary intake and diet quality.SettingPrimary and secondary schools, Québec City, Canada.ParticipantsPhases 1 and 2 included 20 (40 % boys, mean age 11·5 (sd 2·4) years) and 145 (48 % boys, mean age 11·0 (sd 1·9) years) participants, respectively.ResultsPhase 1 resulted in the questionnaire to be used in Phase 2. In Phase 2, the CFA revealed that the seventeen item, three-factor model (CTFEQr17) provided an excellent fit. Internal consistency was good (Cronbach's α: 0·81-0·90). Test-retest reliability was moderate to good (ICC = 0·59, (95 % CI 0·48, 0·70), ICC = 0·78, (95 % CI 0·70, 0·84), ICC = 0·50, (95 % CI 0·38, 0·62) for CR, UE and EE, respectively). CR correlated with EAT-26 score (r = 0·43, P < 0·0001). UE and EE correlated negatively with BMI Z-scores (r = -0;·26, P = 0·003; r = -0;·19, P = 0·03, respectively). CR correlated with the proportion of energy intake from protein and diet quality (r = 0·18, P = 0·04; r = 0·20, P = 0·02, respectively).ConclusionThe CTFEQr17 is suitable to use among French-speaking Canadian young individuals.

Project description:BACKGROUND:Relative to their application with adults there is currently little information about the application of preference-based health-related quality of life (HRQL) instruments among populations of young people. The Child Health Utility 9D (CHU9D) is a paediatric-specific generic preference-based HRQL instrument, recently translated and linguistically validated into Danish (CHU9D-DK). The purpose of this study was to investigate the construct validity of the CHU9D-DK in a sample of Danish high school students. METHODS:All students attending a Danish High School were invited to participate in a web-based survey in January 2018 (N?=?272). The survey included the CHU9D-DK, the young adult version of the Pediatric Quality of Life Inventory™ 4.0 Generic Core Scales (PedsQL), self-reported health status, presence/absence of disability/chronic diseases, life satisfaction, and socio-economic questions. CHU9D-DK utility scores were generated by employing the two scoring algorithms developed from adults in the UK and adolescents in Australia, respectively. Internal consistency, reliability and construct validity of the CHU9D-DK instrument were investigated. RESULTS:Two hundred and twenty-eight (84%) students consented to participate and completed the survey. The mean?±?(standard deviation) values of the CHU9D-DK utilities were 0.84 (0.11) when the UK adult algorithm was applied and 0.70 (0.22), when the Australian adolescent algorithm was applied. The mean PedsQL score was 82.32 (13.14). The CHU9D-DK showed good internal consistency reliability (Cronbach's alpha?=?0.803). Higher levels of health status and life satisfaction were significantly associated with higher CHU9D-DK utility scores regardless of which scoring algorithm was applied (p-values <?0.001). Students living with a disability/chronic disease exhibited significantly lower utility scores relative to their healthy peers (p-values <?0.05). Higher socio-economic status (approximated by financial situation and frequency of family vacations) was also associated with higher utility scores (p-values <?0.005). CONCLUSION:The CHU9D-DK demonstrated good psychometric performance overall and shows potential as a valid and reliable instrument for assessing the HRQL of Danish young people. TRIAL REGISTRATION:ClinicalTrials.gov identifier: NCT03391999, Registered 15 October 2017.

Project description:Objective: Since the properties of health-related quality of life measures vary across samples, studies directly comparing the properties of different measures can be useful in understanding their relative strengths and limitations. We aimed to compare the psychometric properties of the Health Utilities Index Mark III (HUI3) and the Multiple Sclerosis Impact Scale-29 (MSIS-29). Methods: In Spring 2020, North American Research Committee on Multiple Sclerosis (NARCOMS) Registry participants completed the HUI3, MSIS-29, Patient Determined Disease Steps (PDDS) and SymptoMScreen. For the HUI3 and MSIS-29 we assessed floor and ceiling effects, construct validity, and internal consistency reliability. We used relative efficiency to compare the discriminating ability of the two measures with respect to disability. Results: We included 5,664 participants in the analysis, with mean (SD) age 63 (10.1) years; 4,579 (80.8%) were women. For the HUI3 the mean (SD) score was 0.44 (0.32), for the MSIS-29 physical it was 34.0 (24.2) and for the MSIS-29 psychological it was 25.9 (20.4). Neither of the measures had floor or ceiling effects, and internal consistency reliability was > 0.70 for both. The HUI3 and MSIS-29 physical were strongly correlated (r = -0.78; 95%CI:-0.79,-0.77). The correlation between the HUI3 and MSIS-29 psychological was weaker but remained moderately strong (r = -0.64; 95%CI:-0.66,-0.63). After adjusting for sociodemographic and clinical factors, relative efficiency to discriminate between disability (PDDS) groups was highest for the MSIS-29 physical scale, followed by the HUI3. Conclusion: Both measures had adequate validity and reliability. The MSIS-29 physical discriminated between disability groups better than the HUI3.

Project description:Background/Objective: Child-to-parent violence has generated great interest on the part of professionals and researchers in recent years. Consequently, there is a need to provide an assessment instrument that includes a wide range of child-to-parent violence behaviours and all of elements that define this type of violence. Thus, the purpose of the current study was to analyse the structure, reliability and validity of the CPV-Q, an instrument to assess child-to-parent violence behaviours, including the reasons for aggression against parents. Method: A total of 1,386 Spanish adolescents (55.2% females; M age = 14.7, SD = 1.7) were assessed using the CPV-Q. We obtained descriptive statistics of the items, the internal structure of the scale using both exploratory and confirmatory factor analysis, its reliability, and external evidence of its validity. Results: Data indicated a matrix of 4 factors with 14 parallel items (for the father and for the mother). Reasons for child-to-parent violence were grouped into instrumental and reactive reasons. Conclusion: The CPV-Q presents adequate psychometric properties; thus, it is proposed as a useful instrument to assess child-to-parent violence in both professional and research settings.

Project description:OBJECTIVES:To estimate the burden of illness from chronic disease and injury using a population based health survey, which contains both measures of chronic disease and a utility based health related quality of life (HRQOL) measure. DESIGN:An adapted Sullivan method was used to calculate cause deleted health adjusted life expectancies for chronic conditions. SETTING:Ontario, Canada, 1996/97. SUBJECTS:The 1996/97 Ontario Health Survey (n=35 527) was used to estimate the prevalence of chronic conditions. A cause deleted approach was used to estimate the impact of these conditions on the Health Utilities Index (HUI). Cause deleted probabilities of dying were derived with the cause eliminated life table technique and death data from vital statistics for Ontario 1996/97 (n=156 610). RESULTS:Eliminating cardiovascular disease and cancer will cause an "expansion of morbidity", while eliminating mental conditions and musculosketal disorders will result in a "contraction of morbidity". The HUI score varies depending on chronic condition, age, and sex-most of which were assumed not to vary in previous summary measures of population health. CONCLUSIONS:Health adjusted life expectancy estimated for chronic conditions using a utility based measure of health related quality of life from population health surveys addresses several limitations of previous studies that estimate the burden of disease using either a categorical measure of disability or expert opinion and related epidemiological evidence.
