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.

Abstract Background We provide a meta-analysis for clinicians and researchers regarding the psychometric properties of the WOMET as a patient-reported outcome measure (PROM) for patients with meniscal pathologies. Methods A comprehensive literature search identified 6 eligible papers evaluating WOMET measurement properties in patients with different meniscal injuries and meniscal treatments following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The quality of the included studies was evaluated using the four-point Consensus-based Standard for the selection of health Measurement Instruments (COSMIN) Checklist for good measurement properties. The checklist was specifically developed for studies on health-related PROMs. Results Our meta-analysis suggests that the WOMET can be used to evaluate patients with different meniscal injuries and meniscal treatments, especially acute or chronic meniscal injuries and traumatic or degenerative meniscal injuries treated operatively or conservatively. The WOMET shows satisfactory internal consistency, test-retest reliability, and construct validity. Due to limitations in both sample sizes and methodologies of the included studies, no conclusions can be drawn regarding the WOMET’s content validity, structure validity, cross-cultural validity, measurement error, or responsiveness. A further limitation of the studies included in this meta-analysis is the lack of cross-cultural validation, although recommended by the COSMIN Standards. Conclusions The first meta-analysis on measurement properties of the WOMET demonstrates satisfactory internal consistency, test-retest reliability, and construct validity. Further studies are needed, focusing on the methodological deficiencies highlighted in this meta-analysis. To ensure that the WOMET adequately reflects the symptoms, functions, and quality of life of patients with meniscal tears based on COSMIN criteria, it is necessary to assess the structural validity and content validity of this PROM.

Abstract Background and aim Growing attention is being given to utilising physical function measures to better understand and manage knee osteoarthritis (OA). The Fremantle Knee Awareness Questionnaire (FreKAQ), a self-reported measure of body-perception specific to the knee, has never been validated in Italian patients. The aims of this study were to culturally adapt and validate the Italian version of the FreKAQ (FreKAQ-I), to allow for its use with Italian-speaking patients with painful knee OA. Methods The FreKAQ-I was developed by means of forward–backward translation, a final review by an expert committee and a test of the pre-final version to evaluate its comprehensibility. The psychometric testing included: internal structural validity by Rasch analysis; construct validity by assessing hypotheses of FreKAQ correlations with the knee injury and osteoarthritis outcome score (KOOS), a pain intensity numerical rating scale (PI-NRS), the pain catastrophising scale (PCS), and the Hospital anxiety and depression score (HADS) (Pearson’s correlations); known-group validity by evaluating the ability of FreKAQ scores to discriminate between two groups of participants with different clinical profiles (Mann–Whitney U test); reliability by internal consistency (Cronbach’s alpha) and test–retest reliability (intraclass correlation coefficient, ICC2.1); and measurement error by calculating the minimum detectable change (MDC). Results It took one month to develop a consensus-based version of the FreKAQ-I. The questionnaire was administered to 102 subjects with painful knee OA and was well accepted. Internal structural validity confirmed the substantial unidimensionality of the FreKAQ-I: variance explained was 53.3%, the unexplained variance in the first contrast showed an eigenvalue of 1.8, and no local dependence was detected. Construct validity was good as all of the hypotheses were met; correlations: KOOS (rho = 0.38–0.51), PI-NRS (rho = 0.35–0.37), PCS (rho = 0.47) and HADS (Anxiety rho = 0.36; Depression rho = 0.43). Regarding known-groups validity, FreKAQ scores were significantly different between groups of participants demonstrating high and low levels of pain intensity, pain catastrophising, anxiety, depression and the four KOOS subscales (p ≤ 0.004). Internal consistency was acceptable (α = 0.74) and test–retest reliability was excellent (ICC = 0.92, CI 0.87–0.94). The MDC95 was 5.22 scale points. Conclusion The FreKAQ-I is unidimensional, reliable and valid in Italian patients with painful knee OA. Its use is recommended for clinical and research purposes.

This study analyzes the Children's Embedded Figures Test by examining its internal consistency, test-retest reliability, the order of difficulty of the items, and the change of scores with age. Among the sample 337 boys and 287 girls who were between the ages of 6 and 11 years and in the first five grades of primary school scores increased significantly. The test presented moderate internal consistency (.86), and the test-retest reliability after one year was .63. The order of difficulty of the items did not coincide with the order proposed by the test's authors and varied from grade to grade, i.e., in the Tent series Item 4 and in the House series Item 5 were among the most difficult.

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]

Abstract Background This study was focused on translation and cultural adaptation of the English Lequesne Algofunctional index (LAI) into Bengali for patients with primary knee osteoarthritis (OA) and testing reliability and validity of the Bengali version of the LAI. Methods This study was carried out in the Department of Rheumatology, BSM Medical University, Dhaka, Bangladesh. Using the forward–backward method the English LAI was translated into Bengali including cultural adaptation. For pretesting, A sample of 40 patients with primary knee osteoarthritis were screened using the Bengali version of LAI. Following the pretest, 130 consecutive patients with symptomatic knee OA completed the interviewer administered Bengali LAI, the validated Bengali version of SF-36, Visual Analogue Scale for Pain, Distance Walked and Activities of Daily Living. For the retest 60 randomly selected patients from the cohort were administered the Bengali LAI 7 days later. An item by item analysis was performed. Internal consistency was assessed by Cronbach’s alpha, test–retest reliability by intraclass correlation coefficient (ICC) and Kappa coefficient, construct validity was measured using the Spearman rank correlation coefficient. Results It took 3.25 ± 0.71 min to complete the Bengali LAI and the mean score was 9.23 ± 4.58. For the Bengali LAI Cronbach’s alpha score was 0.88, test–retest reliability assessed by ICC was 0.97. For construct validity, excellent convergent validity was achieved (ρ = 0.93) but the divergent validity was moderate (ρ = 0.43). Conclusions The Bengali LAI showed excellent convergent validity, internal consistency and test–retest reliability, only the divergent validity was moderate. So, the Bengali LAI can be applied as a HRQoL assessment tool for primary knee OA patients.
