BACKGROUND: To date the Neck OutcOme Score (NOOS) was not cross-culturally adapted, validated or available in the Arabic language, although it was available in other languages. OBJECTIVE: To translate and cross-culturally adapt the Arabic version of the Neck OutcOme Score (NOOS-Ar) and study its psychometric properties. METHODS: A sample of 146 subjects with chronic neck pain filled in the NOOS-Ar questionnaire to determine the Cronbach’s alpha (α) for internal consistency, test-retest reliability by intraclass correlation coefficients(2,1) [ICC(2,1)], inter-item correlation, measurement error by coefficient of variance and minimal detectable change, ceiling and floor effects, convergent construct validity with visual analog scale (VAS) by Spearman’s rank correlation coefficient (ρ) and factor analysis to calculate and determine its psychometric properties. RESULTS: Excellent internal consistency (Cronbach’s α> 0.9) and test-retest reliability [ICC(2,1)> 0.9] were observed in NOOS-Ar. None of the five subscales of the NOOS-Ar showed a floor or ceiling effect. The coefficient of variance was generally high, but the minimal detectable change was within the acceptable range (< 30%). The ‘everyday activity and pain’ and ‘symptoms’ subscales of the NOOS-Ar, showed a moderate correlation with VAS. CONCLUSION: The NOOS-Ar is highly reliable and has a moderate to good degree of convergent construct validity with VAS with no floor or ceiling effects.

The purpose of this study was to create a valid and reliable instrument to evaluate theory-basedbeliefs towards physical activity among clergy members. Data were collected from 174 clergy that par-ticipated in a 15-item online and paper-based survey. Psychometric properties of the instrument includedconfirmatory factor analysis (construct validity), and cronbach’s alpha (internal consistency reliability).In addition, the stability (test-retest reliability) of each subscale was evaluated with a sub-sample of 30participants. Results show the instrument was both valid and reliable, and will be useful in future studiestargeting this population. Future implications are discussed.

e24027 Background: The ongoing two-part phase 2/3 RESILIENT study (NCT03088813) is investigating the efficacy and safety of liposomal irinotecan monotherapy in patients with SCLC who have progressed on or after first line platinum-based chemotherapy. This exploratory analysis from RESILIENT part 1 was conducted to confirm the psychometric properties of established PRO instruments that had not previously been validated in patients with SCLC. Methods: Patients completed the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ) Core 30 (C30) and the EORTC QLQ Lung Cancer 13 (LC13) before treatment assignment (baseline), every 6 weeks thereafter, at treatment discontinuation and at the 30-day follow-up visit. Psychometric methods included descriptive statistics (items and scales), correlations (item-to-item and item-to-total), internal consistency (Cronbach’s α), test-retest reliability (intraclass correlation coefficient [ICC], two-way random effects model), construct validity and sensitivity to change. The analysis included patients who received at least one dose of study drug and completed at least one PRO assessment. Results: Thirty patients were enrolled in RESILIENT part 1 and included in the analysis. At baseline, 68% of patients reported ‘not severe’ or ‘mild’ symptoms. Floor effects (i.e. more than 25% of responses of ‘not at all’) were observed for several of the functioning/impact and symptom scales of the EORTC QLQ C30 and LC13. Moderate to strong correlations were found among most questionnaire items within their respective scales. Acceptable evidence for internal consistency and good test-retest reliability were observed. Selected results for the EORTC QLQ LC13, including dyspnea scales, are shown in the Table. The magnitude of correlations among PRO instruments supported evidence for convergent validity in this sample. Conclusions: In RESILIENT part 1, patients experienced low and tolerable symptoms at enrollment, limiting the potential for further improvement. Overall, these PRO instruments had acceptable psychometric properties (e.g. construct validity, reliability and ability to detect change) in this sample. However, these analyses should be repeated in a larger sample using data from RESILIENT part 2. Clinical trial information: NCT03088813. [Table: see text]

Oral Impacts

Background/Aim. Among numerous sociodental indicators the Oral Impacts on Daily Performance (OIPD) is one of the most broadly applied. The aim of this study was to develop and test psychometric properties of a Croatian version of OIDP scale. Methods. The OIDP instrument was translated from English to Croatian in a forward-backward method. The Croatian version was tested for reliability, construct validity and responsiveness on a sample of 702 participants (255 men), aged 18-86 years. Results. Internal consistency of Croatian version of the OIDP was acceptable (alpha = 0.80) and 69.4% of the examinees had oral impacts relating to one or several performances. The most frequently affected performance was eating (53.7%). The test-retest reliability was high (r = 0.99; 95% CI: 0.97-0.99), the mean difference between the OIDP summary scores in two-week interval was not statistically significant. In construct validity testing there was statistically significant correlation between OIDP and self-assessed general and oral health, somatisation, depression and Oral Health Impact Profile ranging from 0.157 to 0.516. Responsiveness was confirmed by a significant reduction of oral impacts on daily performances in subjects before and after treatment of acute dental pain (p < 0.001). Conclusion. The Croatian OIDP index showed good psychometric properties in terms of construct validity, internal consistency, test-retest reliability and responsiveness confirming its appropriateness for use among Croatian population.

Stressor Scale

The lack of a suitable assessment tool may limit optimal stress management and impair the health-related quality of life of patients undergoing hemodialysis. The purpose of the study was to examine latent constructs and psychometric properties of the Vietnamese Hemodialysis Stressor Scale (HSS-V). In total, 180 patients receiving hemodialysis were recruited. Psychometric properties of the HSS-V, including the construct validity, internal consistency, and test–retest reliability, were tested after the instrument translation. The exploratory factor analysis resulted in a 24-item HSS-V with four extracted factors, which explained 58.32% of the total variance. The construct validity was confirmed by significant negative correlations between scores on the HSS-V and Vietnamese-version Short Form-36. The internal consistency (Cronbach’s α = .82-.91) and test–retest reliability (intra-class correlations coefficient = .91-.94) of the 24-item HSS-V were satisfactory. A simple structure and preliminary acceptable psychometric properties of the HSS-V were established and can serve as a basis for further studies.

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. 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 Anxiety and depression are common in children and adolescents. These disorders can be detected via self-report screening questionnaires in a non-clinical setting like the school environment. Two short versions of the Revised Child Anxiety and Depression Scale (i.e., RCADS-25 and RCADS-20) seem to be feasible for administering in schools. However, it should be examined whether its promising psychometric properties can be replicated and whether knowledge on remaining psychometric properties can be added. This study evaluates the psychometric properties of the RCADS-25 and RCADS-20 used as screening instruments for anxiety and depression in schoolchildren and adolescents. Methods The RCADS-25 was completed by 69,487 schoolchildren and adolescents age 8 to 18 years. The RCADS-25/RCADS-20 broad anxiety scale (15 items), the RCADS-25 major depressive disorder (MDD) scale (10 items), and the RCADS-20 MDD scale (5 items) were assessed on construct validity (structural validity and hypotheses testing), reliability (internal consistency and test-retest reliability), and criterion validity in conformance with internationally consensus-based COSMIN definitions, taxonomy and quality criteria. Results The RCADS-25/RCADS-20 broad anxiety scale demonstrated a sufficient structural validity (CFI = 0.98, TLI = 0.99, RMSEA = 0.03, SRMR = 0.03), internal consistency (alpha = 0.82), test-retest reliability (ICC = 0.73), criterion validity (AUC = 0.79), and all four hypotheses concerning construct validity were confirmed. The RCADS-25 MDD scale demonstrated a sufficient test-retest reliability (ICC=0.70), and three out of four hypotheses testing construct validity were confirmed, but its structural validity was suspect (CFI = 0.89, TLI = 0.94, RMSEA = 0.09, SRMR = 0.06). The RCADS-20 MDD scale demonstrated a sufficient structural validity (CFI = 0.97, TLI = 0.97, RMSEA = 0.08, SRMR = 0.04) and internal consistency (alpha = 0.72), but two out of four hypotheses concerning construct validity were confirmed, while the test-retest reliability (ICC = 0.60) seemed insufficient. Conclusions The RCADS-25/RCADS-20 broad anxiety scale seems valid and reliable for screening schoolchildren and adolescents, but the RCADS-25 and RCADS-20 MDD scales show shortcomings. An MDD scale of seven items that showed acceptable psychometric properties is recommended.

Abstract Background The Michigan Hand Questionnaire (MHQ) is widely used to assess the hand/wrist conditions. We translated the original version into Thai (Thai MHQ) and evaluated its psychometric properties. Methods After receiving permission, the original MHQ was translated and cross-culturally adapted to Thai following standard guidelines. Two hundred and seventeen patients who had hand/wrist injuries or disorders were included in the study. Internal consistency was evaluated using Cronbach’s alpha. Test-retest reliability was analyzed using the intraclass correlation coefficient (ICC). Spearman’s rank correlation among the subscales of Thai MHQ, Thai DASH and Thai EQ-5D-5L and also confirmatory factor analysis (CFA) were used to explore construct validity. The standardized response mean (SRM) was used to evaluate the responsiveness of the Thai MHQ. Results All subscales showed an acceptable Cronbach’s alpha (0.79–0.98). The test-retest reliability of each subscale was good (ICC = 0.83–0.95). In related dimensions, strong correlation was demonstrated between the Activities of daily living subscale of the Thai MHQ and the Common activities subscale in the Thai DASH (r = 0.77, P < 0.0001). For unrelated dimensions, a weak correlation was found between the Aesthetics subscale in the Thai MHQ and the Mobility subscale in the Thai EQ-5D-5L (r = − 0.13, P = 0.05). The Thai MHQ had strong correlation with Thai DASH (r = − 0.79, P < 0.0001) and Thai EQ-5D-5L (r = 0.63, P < 0.0001). CFA showed that the 6-factor model demonstrated an acceptable fit to the data. The SRM of the Thai MHQ was 0.78, indicating relatively large responsiveness. The MIC of Thai MHQ using distribution methods (SEM) was 5.2. Conclusions The Thai MHQ provides adequate internal consistency in all subscales as well as good construct validity and reliability for Thai patients and a relatively large standardized response mean at 2 months after treatment.

Background: The Copenhagen Burnout Inventory (CBI) is a commonly used tool for evaluation of job burnout in three (personal, work-related and client-related) domains. The aims of this study were to translate and investigate the psychometric properties of the Iranian (Persian) CBI. Methods: A total of 750 employees of different occupations (from educational centres, healthcare, industrial settings, and social services) participated in this descriptive methodological study. Aforward-backward procedure was applied and content validity was evaluated by a panel of10 experts. Exploratory and confirmatory factor analyses were used for construct validity. The internal consistency (using Cronbach’s alpha), test-retest reliability (using intraclass correlation coefficient – ICC), and feasibility (using ceiling and floor effect) were also assessed for this tool. Results: Content validity of the Persian CBI was established. Three-factor structure of the PersianCBI was supported by the factor analysis, and this confirmed the construct validity of the instrument. The internal consistency (Cronbach’s alpha ranged from 0.82 to 0.90) and test-retest reliability (ICC ranged from 0.85 to 0.95) were excellent and there was no ceiling or floor effect. Conclusion: The Persian CBI is a valid and reliable measurement tool for burnout in the Iranian context.

Abstract Background Hemodialysis is considered a major therapeutic method for patients with chronic kidney disease. Pruritus is a common complaint of hemodialysis patients. The 5-D pruritus scale is amongst the most common tools to evaluate several dimensions of itch. Psychometric properties of the 5-D scale have not been evaluated in Persian speaking population with hemodialysis; hence, the objective of this study was to assess reliability and validity of the Persian version of the scale. Methods Ninety hemodialysis patients (men: 50, women: 40, mean age: 54.4 years) participated in this cross-sectional study. The final Persian version of 5-D scale was given to the participants. Tests Compared: One-third of the participants completed the scale twice within 3–7 days apart to evaluate test- retest reliability. Other psychometric properties including internal consistency, absolute reliability, convergent, discriminative and construct validity, floor/ceiling effects were also evaluated. Results The Persian 5-D scale has strong test-retest reliability (ICC= 0.98) and internal consistency (Cronbach’s alpha= 0.99). Standard error of measurement and minimal detectable change were 0.33 and 0.91, respectively. Regarding convergent validity, the scale had moderate correlation with numeric rating scale (r =0.67) and quality of life questionnaire related to itch (r = 0.59). Exploratory factor analysis revealed two factors within the scale. No floor or ceiling effect was found for the scale. Conclusion The Persian version of 5-D the itching scale is a brief instrument with acceptable reliability and validity. Therefore, the scale could be used by experts, nurses, and other health service providers to evaluate pruritus among Persian speaking hemodialysis patients.
