Background: High-quality scales (HQS) suitable that measure symptoms and adaptive behaviors (AB) with proven validity and reliability are needed for different age groups of children with eosinophilic esophagitis (EoE).Objective: To develop a high-quality pediatric EoE symptoms and AB scale for different age groups. Methods: Children (7-11 years), teens (12-18 years), and parents of 2-18-year-old children with EoE were included. A HQS should have encompassed: the identification of domain and item generation; content validity (CnV) and field test for construct validity (CsV) and reliability. Convergent validity (CgV) was examined for CsV. Correlations between the Pediatric Eosinophilic Esophagitis Symptom Score, version 2.0 (PEESS v2.0) and Gazi University Eosinophilic Esophagitis Symptoms and Adaptive Behavior Scale (GaziESAS) version 2.0 (v2.0) were examined for CgV. Reliability was determined through internal consistency (Cronbachα) and test-retest reliability (intraclass correlation coefficients: ICC).Results: Nineteen children, 42 teens, and 82 parents completed the study. GaziESAS v2.0 was composed of 20 items with two main domains: symptoms (subdomains: dysphagia and nondysphagia) and AB. CnV indexes were excellent for all items. The CgV varied from good to excellent correlation (r = 0.6 to r = 0.9). GaziESAS v2.0 showed good reliability (Cronbachα >0.7 and ICC >0.6).Conclusion: GaziESAS v2.0 is the first pediatric HQS that measures the frequency of symptoms and AB in EoE within the last month with separate forms for children, teens, and parents.

“…After evaluating the measurement properties, Carreon et al[ 5 ] recommended refining their version of the SAQ to a 14-item questionnaire based on two domains (appearance and expectations) with less burden for the AIS patient. This two-domain version has been translated and cross-cultural adapted into multiple versions of the SAQ and their measurement properties were evaluated [ 5 – 9 ]. Since no validated Dutch version of the SAQ exists, this study aimed to translate and cross-culturally adapt the recommended short English version of the SAQ into Dutch and to evaluate its measurement properties in AIS patients in The Netherlands.…”

Purpose Adolescent idiopathic scoliosis (AIS) affects the appearance of spine and trunk. The Spinal Appearance Questionnaire (SAQ) assesses the perception of appearance in AIS patients. The aim of this study is to translate and culturally adapt the recommended short version of the SAQ into Dutch and to test its measurement properties. Methods A Dutch SAQ (14-item; appearance and expectations domains) was developed following guidelines for translation and cross-cultural adaptation. The COSMIN Study Design checklist was used for measurement properties evaluation. In this multicenter study, the Dutch SAQ, SRS-22R and NPRS (back pain) were administered to 113 AIS patients (aged 15.4 years [SD 2.2], 21.2% male). Floor and ceiling effects were evaluated for content analysis. For reliability, internal consistency (Cronbach’s alpha) and test–retest reliability (ICC; n = 34) were evaluated. Predefined hypotheses of relationships with other questionnaires and between subgroups based on scoliosis severity (radiological and clinical) were tested for construct validity. Exploratory factor analysis (EFA) was performed to investigate the validity of the underlying structure of this 14-item questionnaire. Results No floor and ceiling effects were found for domains and total scores. Cronbach’s alpha ranged from 0.84 to 0.89. ICCs varied from 0.76 to 0.77. For construct validity, 89% (8/9) of the predefined hypotheses were confirmed. Significant higher scores for the appearance domain were found for subgroups based on radiological (Cobb angle; > 25.0°) and clinical outcomes. (Angle of Trunk Rotation; > 9.0°). A two-factor structure was found (EV 5.13; 36.63% explained variance). Conclusion The Dutch SAQ is an adequate, valid and reliable instrument to evaluate patients’ perception of appearance in AIS. Level of evidence Level I—diagnostic studies.

Adolescent idiopathic scoliosis (AIS) and Scheuermann's kyphosis (SK) are the most common types of spinal deformities in adolescents, and both have substantial ramifications on health-related quality of life (HRQoL) parameters. Various questionnaires have been developed to assess HRQoL in age-group populations with spinal deformity. Nevertheless, there remains a lack of consensus across the literature as to which instrument is the most suitable for evaluating the HRQoL of this cohort. Thus, this literature review was conducted to present disease-specific questionnaires for children and adolescents with AIS and SK to provide their psychometric characteristics (validity, reliability, and responsiveness) across different languages. A literature search was performed in the Medline (PubMed), Scopus, EMBASE, and Google Scholar databases. Studies that outlined the development and application of questionnaires evaluating HRQoL of children and adolescents with spinal deformity were included, and data on their validity and reliability in different translated languages were collected. A total of 10 disease-specific questionnaires were identified. Except for one questionnaire that was a proxy-reported measure, the other questionnaires were self-reported.We determined that selecting the proper questionnaire for clinical and research purposes requires careful consideration of various factors including the type of treatment intervention planned as well as various patient demographic factors. For children with early-onset scoliosis, the ideal questionnaire to evaluate their HRQoL is the Early-Onset Scoliosis Questionnaire-24. For adolescents with AIS and SK who are potential candidates for surgical intervention, the use of
