<p>Hajj Instrument (HAJI) was developed to determine hajj pilgrim’s wellness. This study used Rasch measurement to evaluate the psychometric properties including validity and reliability of the HAJI. The respondents involved in this study were 300 comprised of Malaysian hajj pilgrims. HAJI consists of eight constructs namely physical care, physical activity, healthy eating, knowledge, mental toughness, intrapersonal, interpersonal and relationship with Creator and natures. Validity of each construct and content was determined through dimensionality, item fit and item polarity while the reliability was achieved by administered person and item separation. The results showed that the reliability for both item and person were 0.99 and 0.96 respectively. Besides, there were no items need to be dropped based on PTMEA CORR and INFIT MNSQ results. The study revealed that the items of HAJI fit the Rasch model as well as able to measure hajj pilgrim’s wellness. </p>

Objective: To identify self-reported outcome measures specific to the foot and ankle in patients with rheumatoid arthritis and to investigate the methodological quality and psychometric properties of these measures. Method: A systematic review focusing on patients with rheumatoid arthritis. Setting: The search was conducted in the PubMed, SCOPUS, CINAHL, PEDro and Google Scholar databases, based on the following inclusion criteria: population (with rheumatoid arthritis) > 18 years; psychometric or clinimetric validation studies of patient-reported outcomes specific to the foot and ankle, in different languages, with no time limit. Two of the present authors independently assessed the quality of the studies located and extracted the relevant data. Terwee’s criteria and the COSMIN checklist were employed to ensure adequate methodological quality. Results: Of the initial 431 studies considered, 14 met the inclusion criteria, representing 7,793 patients (56.8 years). These instruments were grouped into three dimensions (pain, perceived health status and quality of life and disability). The time to complete any of the PROMs varies around 15 minutes. PROMs criterias with the worst scores by COSMIN, 92.85% and 85.71% were criterion validity, measurement error, internal consistency and responsiveness. 28.57% of PROMs were compared with the measurement properties. Conclusion: the Self-Reported Foot and Ankle Score achieved the highest number of positive criteria (according to Terwee and COSMIN), and is currently the most appropriate for patients with Rheumatoid arthritis.

Abstract. Mindfulness-based interventions are found beneficial to improving well-being and alleviating symptoms of psychological distress, although accurate measurement of the psychological construct of mindfulness remains a challenge. Theoretical work has highlighted characteristics of mindfulness, which can be assessed comprehensively by the recently developed eight-factor Comprehensive Inventory of Mindfulness Experiences (CHIME). While the instrument has demonstrated acceptable psychometric properties, its ability to discriminate precisely across individual mindfulness levels has not been rigorously investigated. The current study subjected responses of 443 participants to Rasch analysis to investigate and enhance the psychometric properties of the CHIME. The best fit to the Rasch model was achieved for every individual subscale with only minor modifications that involved combining some locally dependent items into a testlet. The total scale was then fitted to the Rasch model with individual subscales treated as testlets, and the best model fit was attained after two correlated subscales were treated as a single testlet, χ2(63) = 70.76, p = .23. Therefore, it was possible to generate ordinal-to-interval conversion tables for individual subscales and the total scale scores, which increase the instrument’s precision. The results support internal construct validity and enhance psychometric properties of the CHIME.

SummaryInstruments developed to measure anhedonia are reviewed and their psychometric properties and conceptual framework discussed. Most instruments were designed considering anhedonia to be a symptom either of schizophrenia or of depression. Only the Physical and Social Anhedonia Scales of Chapman et al, designed to measure a lifelong pleasure deficiency, considered to be related to schizophrenia, and, to a lesser extent, the Pleasure Scale of Fawcett et al, designed to evaluate a state dependent deficit, considered to identify a subtype of depression, have been psychometrically extensively investigated. Since we were interested in studying anhedonia in depression, we made a Dutch translation of the Fawcett-Clark Pleasure Scale and report here on the psychometric properties of this translated version. Using the Rasch model for testing the homogeneity and transferability of the scale, we demonstrated that the original scale did not fit the model. A subscale of 14 items was constructed which did.

Category: Ankle Introduction/Purpose: The evaluation process is essential to optimize the management of patients with foot and ankle pathologies and disorders. The study aimed to translate and culturally adapt the four scoring systems of the American Orthopaedic Foot & Ankle Society Score (AOFAS) into Arabic and explore related psychometric properties. Methods: A multicenter observational design was used, following the forward-backward translation method. One hundred and twenty patients with foot and ankle problems were included. Construct validity and test-retest reliability were analyzed using Intra-class correlation coefficients; internal consistency was analyzed with Cronbach’s alpha, and the responsiveness was analyzed using a paired-sample test. Results: The validity ranged from 0.303-0.542 and from 0.018-0.753 when correlated to the SF-12 physical and mental component scores, respectively. Test-retest reliability ranged from 0.727-0.974; from 0.826-0.983 for internal consistency and from 0.001-0.182 for sensitivity. Conclusion: The AOFAS’s four systems were successfully translated and culturally adapted into Arabic with sufficient psychometric properties.

Abstract Background Reliable and valid measurement is the foundation of evidence-based practice. The self-administered Foot Health Assessment Instrument (S-FHAI) was recently developed to measure patients’ evaluations of their own foot health. Evidence regarding the psychometric properties of the S-FHAI is limited. The aim of this study was to investigate those properties by using a Rasch analysis. Methods This methodological study analysed secondary data that was collected from nurses (n = 411) in 2015. The psychometric properties of the S-FHAI were evaluated using the Rasch model. Unidimensionality was analysed first, followed by item functioning, person misfit and differential item functioning (DIF). Results The S-FHAI demonstrated evidence of unidimensionality, with an acceptable item fit according to the Rasch model. Person fit and person separation were low, however, indicating restricted separation among different respondents. Item separation was high, demonstrating clear discrimination between the items. No DIF was detected in relation to gender, but significant DIF was demonstrated in relation to age for 6 of the 25 items. Conclusions The S-FHAI has potential for use in investigating self-reported foot health. The Rasch analysis revealed that the psychometric properties of the instrument were acceptable, although some issues should be addressed to improve the scale. In future, it may be beneficial to analyse the sensitivity of the items and to test the S-FHAI in more diverse patient populations.
