OBJECTIVE: To translate, culturally adapt, and validate the psychometric characteristics of the Italian version of the Dance Functional Outcome Survey (DFOS-IT) in adult dancers. DESIGN: Clinical measurement study. METHODS: The DFOS-IT was forward translated, reconciled, backward translated, and reviewed by an expert committee to establish optimal correspondence with the original English DFOS. We examined test-retest reliability in 58 dancers within a 10-day period, using intraclass correlation coefficients (ICC2,1). In a sample of 265 healthy and injured dancers, the following were examined: 1) construct validity, comparing the DFOS-IT to SF-36 using Pearson correlations; 2) exploratory factor analysis and internal consistency; and 3) sensitivity, by generating receiver operating characteristic curves and determining area under the curve (AUC). In a subgroup of 44 dancers, we determined internal responsiveness across three time-points using repeated measures ANOVA (p<0.05). Injured dancers’ scores were analyzed for floor and ceiling effects. RESULTS: The DFOS-IT demonstrated very high test-retest reliability (ICC=0.98). Single-factor loading in exploratory factor analysis supported unidimensionality of the scale, with high internal consistency (a=0.93). DFOS-IT total, activities of daily living (ADL), and Dance Technique scores had strong construct validity compared with scores on the SF-36 PCS (r=0.71). There was excellent sensitivity, with high AUC values (AUC=0.80). There were significant differences across time for DFOS-IT scores (p<0.001), demonstrating responsiveness to change, and no floor or ceiling effects. CONCLUSION: The DFOS-IT is a valid, reliable, and responsive tool that can be used as an outcome and screening measure for Italian adult ballet and modern dancers following lower extremity or low back injury.

Introduction Several general hand functional assessment tools for Dupuytren’s disease have been reported, but none of the patient-reported-outcome measures specific to Dupuytren’s disease-associated disabilities are available in the Italian language. The purpose of this study was to culturally adapt the Unité Rhumatologique des Affections de la Main (URAM) into Italian (URAM-I) and determine its measurement properties. Methods Cross-cultural adaptation was performed according to the current guidelines. Construct validity (convergent and divergent validity) was measured by comparing the URAM-I with the Pain-Rated Wrist/Hand Evaluation (PRWHE-I), Short-Form 36 (SF-36-I) scale and finger range of motion, respectively. Factor analysis was used to investigate the URAM-I’s internal structure. Reliability was assessed by internal consistency (Cronbach’s alpha) and test-retest reliability by Intra-Class Correlation Coefficient (ICC). Results This study included 96 patients (males = 85%, age = 66.8 ± 9.3). Due to the cultural adaptation, we divided the original item #1 into two separate items, thus generating the URAM-I(10). Convergent validity analysis showed a strong positive (r = 0.67), significant (p < 0.01) Pearson’s correlation with the PRWHE-I. Divergent validity analysis showed a weak, negative (r < 0.3) and not significant correlation with the SF-36-I subscales, except for the physical pain subscale (r = −0.21, p < 0.05). Factor analysis revealed a 2-factor, 4-item solution that explained 76% of the total variance. The URAM-I(10) demonstrated high internal consistency (α = 0.94) and high test-retest reliability (ICC = 0.97). Conclusion The URAM-I(10) demonstrates moderate construct validity, high internal consistency and test-retest reliability, and showed a 2-factor internal structure. Its evaluative use can be suggested for the Italian Dupuytren’s population.

Background: Curiosity is a personality characteristic, which fits with wellbeing and positive functioning. The objective of this study was to assess the construct validity of the Curiosity and Exploration Inventory II (CEI-II) in Indonesia.Design and Methods: The study included 256 undergraduate students who lived in Indonesia, mean age 19.8 years old. The CEI-II measures stretching and embracing using 11 items. The English version of CEI-II was translated into Bahasa. The Cronbach’s alpha coefficient and intraclass correlation coefficient (ICC) were addressed to examine internal consistency reliability and the test-retest reliability. To evaluate construct validity, exploratory factor analysis (EFA) was used to assess factor structure and confirmatory factor analysis (CFA) was used to evaluate the structural model fit of the CEI-II Indonesia version.Results: The study showed Cronbach’s alpha for the internal consistency of the overall CEI-II Indonesia version was 0.77. The ICC for the test-retest reliability ranged between 0.753-0.829. EFA showed adequate with the Kaiser-Meyer-Olkin value of 0.86 and the Bartlett’s test of sphericity was statistically significant. CFA tested the second-order model with two-order factors and showed a model fit.Conclusions: The CEI-II Indonesia version indicated acceptable construct validity to evaluate curiosity in Indonesia.

Background There is little evidence for the measurement properties of instruments commonly used for women with pelvic girdle pain. Objective The aim of this study was to examine the internal consistency, test-retest reliability, and construct validity of instruments used for women with pelvic girdle pain. Design This was a cross-sectional methodology study, including test-retest reliability assessment. Methods Women with pelvic girdle pain in pregnancy and after delivery participated in a postal survey that included the Pelvic Girdle Questionnaire (PGQ), Oswestry Disability Index (ODI), Disability Rating Index (DRI), Fear-Avoidance Beliefs Questionnaire (FABQ), Pain Catastrophizing Scale (PCS), and 8-item version of the Medical Outcomes Study 36-Item Short-Form Health Survey questionnaire (SF-36). Test-retest reliability was assessed with a random subsample 1 week later. Internal consistency was assessed with the Cronbach alpha, and test-retest reliability was assessed with the intraclass correlation coefficient (ICC) and minimal detectable change (MDC). Construct validity based on hypotheses was assessed by correlation analysis. Discriminant validity was assessed with the area under the receiver operating characteristic curve. Results All participants responded to the main (N=87) and test-retest (n=42) surveys. Cronbach alpha values ranged from .88 to .94, and ICCs ranged from .78 to .94. The MDC at the individual level constituted about 7% to 14% of total scores for the 8-item version of the SF-36, ODI, and PGQ activity subscale; about 18% to 22% for the DRI, PGQ symptom subscale, and PCS; and about 25% for the FABQ. Hypotheses were mostly confirmed by correlations between the instruments. The PGQ was the only instrument that significantly discriminated participants who were pregnant from participants who were not pregnant as well as pain locations. Limitations A comparison of responsiveness to change of the various instruments used in this study was not undertaken, but will be carried out in a future study. Conclusions Self-report instruments for assessing health showed good internal consistency, test-retest reliability, and construct validity for women with pelvic girdle pain. The PGQ was the only instrument with satisfactory discriminant validity, thus, it is recommended for evaluating symptoms and disability in patients with pelvic girdle pain.

Background Adequate muscle strength, power, and endurance are important in children's daily activities and sports. Various instruments have been developed for the assessment of muscle function; each measures different aspects. The Functional Strength Measurement (FSM) was developed to measure performance in activities in which strength is required. Objective The study objective was to establish the test-retest reliability and structural and construct validity of the FSM. Design A cross-sectional descriptive study was conducted. Methods The performance of 474 children with typical development on the FSM was examined. Test-retest reliability (n=47) was calculated with the intraclass correlation coefficient (2.1A) for agreement. Structural validity was examined with exploratory factor analysis, and internal consistency was established with the Cronbach alpha. Construct validity was determined by calculating correlations between FSM scores and scores obtained with a handheld dynamometer (HHD) (n=252) (convergent validity) and between FSM scores and scores on the Movement Assessment Battery for Children–2 (MABC-2) (n=77) (discriminant validity). Results The test-retest reliability of the FSM total score ranged from .91 to .94. The structural validity revealed one dimension, containing all 8 FSM items. The Cronbach alpha was .74. The convergent validity with the HHD ranged from .42 to .74. The discriminant validity with MABC-2 items revealed correlations that were generally lower than .39, and most of the correlations were not significant. Exploratory factor analysis of a combined data set (FSM, HHD, and MABC-2; n=77) revealed 2 factors: muscle strength/power and muscle endurance with an agility component. Limitations Discriminant validity was measured only in children aged 4 to 6 years. Conclusions The FSM, a norm-referenced test for measuring functional strength in children aged 4 to 10 years, has good test-retest reliability and good construct validity.

Abstract Background The patient self-report section of the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASESp) is one of the most validated and reliable assessment tools. This study aimed to establish a validated Chinese version of ASESp (ASESp-CH). Methods A clinical prospective study was performed (ClinicalTrials.gov Identifier: NCT04755049; registered on 2021/02/11). Following the guidelines of forward-backward translation and cross-cultural adaptation, a Chinese version of ASESp was established. Patients older than 18 years with shoulder disorders were included. Patients who could not complete test-retest questionnaires within the interval of 7–30 days and patients who received interventions were excluded. Intraclass correlation (ICC) was calculated for test- retest reliability, whereas internal consistency was determined by Cronbach value. Construct validity was evaluated by comparing the corresponding domains between the ASESp-CH and a validated Chinese version of 36-Item Short Form Health Survey (SF-36). Results A total of 86 patients were included with a mean test-retest interval of 12 ± 5.4 days. Test-retest reliability was excellent with an ICC of 0.94. Good internal consistency was found, with a Cronbach alpha of 0.86. Construct validity of the ASESp-CH questionnaire was good. The major domains of the ASESp-CH were significantly correlated with the respective domains in the SF-36 (p <  0.01), except for the domain of stability of ASESp-CH. Conclusions The Chinese version of ASESp questionnaire is a highly validated and reliable tool for shoulder disorder assessment.

Activity Enjoyment

Objective: The purposes of this paper were to (a) develop a new short, theory-driven, version of the physical activity enjoyment scale (PACES-S) using content analysis; and (b) subsequently to measure the psychometric properties (construct validity, internal consistency, test–retest reliability, and concurrent validity) of the PACES-S for adolescents. Methods: Six experts used a four-point Likert scale to assess the content validity of each of the 16 items of the physical activity enjoyment scale according to a provided definition of physical activity enjoyment. Based on the results, exploratory factor analysis was used to analyze survey data from a longitudinal study of 182 individuals (Measure 1 of Study 1: 15.75 ± 3.39 yrs; 56.6% boys, 43.4% girls), and confirmatory factor analysis (Measure 2 of Study 1: 15.69 ± 3.44 yrs; 56.3% boys, 43.7% girls) was used to analyze the survey data from a cross-sectional study of 3219 individuals (Study 2; 15.99 ± 3.10 yrs; 47.8% boys, 52.2% girls) to assess the construct validity of the new measure. To assess the reliability, test–retest reliability was assessed in Study 1 and internal consistency in Study 1 and 2. For the concurrent validity, correlations with self-reported and device-based physical activity behavior were assessed in both studies. Results: Four out of sixteen items were selected for PACES-S. Exploratory factor analysis and confirmatory factor analyses identified and supported its factorial validity (χ2 = 53.62, df = 2, p < 0.001; RMSEA = 0.073; CFI = 0.99; RFI = 0.96; NFI = 0.99; TLI = 0.96; IFI = 0.99). Results showed good test–retest reliability (r = 0.76) and internal consistency (a = 0.82 to 0.88). Regarding concurrent validity, the results showed positive correlations with a physical activity questionnaire (Study 1: r = 0.36), with a physical activity diary (Study 1: r = 0.44), and with accelerometer-recorded data (Study 1: r = 0.32; Study 2: r = 0.21). Conclusions: The results indicate that PACES-S is a reliable and valid instrument that may be particularly useful to measure physical activity enjoyment in large-scale studies. It shows comparable measurement properties as the long version of PACES.

Abstract Background Outcome measurement is an essential part of the evaluation of palliative care and the measurements need to be reliable, valid and adapted to the culture in which they are used. The Integrated Palliative Outcome Scale (IPOS) is a widely used tool for assessing outcomes in palliative care. The aim of this study was to provide Czech version of IPOS and asses its psychometric properties.Methods Patients receiving palliative care in hospice or hospitals completed IPOS and part of the sample also completed Edmonton Symptom Assessment System (ESAS) and Palliative Performance Scale (PPS). The reliability of Czech IPOS was tested with Cronbach alpha (internal consistency) and Intraclass correlation coefficient and Weighted Kappa (test-retest reliability). Construct validity was assessed with factor analysis (Exploratory Factor Analysis) and convergent validity was tested with correlation analysis (Spearman correlation).Results Sample consisted of 140 patients (mean age 72; 90 women; 81% oncologic disease). IPOS internal consistency was 0.789; ICC= 0.88. To study convergent validity, we assessed the correlations of IPOS with ESAS (R= 0.4) and PPS (R= -0.2), however, these results have to be considered preliminary due to the small sample size. Exploratory factor analysis revealed a 2-factor solution on our data. The first factor covers emotional and information needs and the second factor covers physical symptoms.Conclusion Czech IPOS has very good reliability regarding both internal consistency and test-retest reliability. Together with an item analysis results, we can conclude that the Czech adaptation of the tool was successful. The convergent validity needs to be assessed on the larger sample and the proposed 2-factor internal structure of the questionnaire has to be confirmed by using CFA.

Abstract Background. The aim of this study was to translate, culturally adapt and validate an Italian version of the Athlete Fear Avoidance Questionnaire (AFAQ-I).Methods. We conducted a cross-sectional evaluation of the psychometric properties of the AFAQ-I in athletes with musculoskeletal injuries, culturally adapting it in accordance with international standards. Psychometric evaluation included exploratory factor analysis, reliability (internal consistency [Cronbach’s alpha], inter-item correlation, and test–retest reliability [intra-class correlation coefficient]). To examine construct validity, we compared (Spearman rank correlation) the AFAQ-I with a numerical pain rating scale (NPRS), the Pain Catastrophizing Scale (PCS), and the Fear Avoidance Beliefs Questionnaire subscales (Physical Activity, FABQ-PA; and Work, FABQ-W). We evaluated sensitivity to change through the minimum detectable change (MDC).Results. The AFAQ-I was administered to 133 university athletes with musculoskeletal injuries (26 females, mean age 25.3 ± 5 years, mean average pain duration 5.6 ± 8.7 months), and resulted acceptable. Factor analysis revealed a 1-factor 10-item solution (explained variance: 53%). Internal consistency was 0.78; average inter-item correlation 0.27; test–retest reliability ICC(2,1) 0.95. As hypothesized a priori, construct validity showed moderate correlations of the AFAQ-I with NPRS (ρ = 0.42), PCS (ρ = 0.59), FABQ-PA (ρ = 0.40) and FABQ-W (ρ = 0.34). The MDC was 4.42 points.Conclusion. The AFAQ-I is a valid Italian translation of AFAQ and demonstrates acceptable psychometric properties. We can recommend its use for clinical and research purposes.

Abstract Background: Outcome measurement is an essential part of the evaluation of palliative care and the measurements need to be reliable, valid and adapted to the culture in which they are used. The Integrated Palliative Outcome Scale (IPOS) is a widely used tool for assessing personal-level outcomes in palliative care. The aim of this study was to provide Czech version of IPOS and asses its psychometric properties. Methods: Patients receiving palliative care in hospice or hospitals completed the IPOS. The reliability of Czech IPOS was tested with Cronbach alpha (for internal consistency), the intraclass correlation coefficient for total IPOS score and weighted Kappa (for test-retest reliability of individual items). Factor analysis was used for elucidating the construct (Exploratory Factor Analysis). Convergent validity was tested with correlation analysis (Spearman correlation) in a part of the sample, who completed also the Edmonton Symptom Assessment System (ESAS) and the Palliative Performance Scale (PPS). Results: The sample consisted of 140 patients (mean age 72; 90 women; 81 % oncological disease). The Cronbach alpha was 0.789; intraclass correlation was 0.88. The correlations of IPOS with ESAS was R= 0.4 and PPS R= -0.2. Exploratory factor analysis revealed a 2-factor solution on our data. The first factor covers emotional and information needs and the second factor covers physical symptoms. Conclusion: Czech IPOS has very good reliability regarding both internal consistency and test-retest reliability. Together with an item analysis results, we can conclude that the Czech adaptation of the tool was successful. The convergent validity needs to be assessed on the larger sample and the proposed 2-factor internal structure of the questionnaire has to be confirmed by using CFA.
