DEVELOPMENT AND VALIDATION OF A CROSS-CULTURAL EORTC MEASURE OF SPIRITUAL WELLBEING (SWB) FOR PALLIATIVE CARE PATIENTS WITH CANCER
2014
Introduction Spiritual care and spiritual wellbeing (SWB) are central to palliative care, but no measures of SWB have yet been developed cross-culturally. Aim(s) and method(s) In 2002 the EORTC Quality of Life (QL) Group began international development of an SWB measure for palliative patients. Three domains of SWB were initially hypothesised, and items developed accordingly. Data for Phase IV field-testing and validation of the measure were collected from January 2012 to July 2013. Participants completed the 36-item provisional SWB measure and a structured debriefing interview. EORTC QLQ-C15-PAL, socio-demographic and clinical data were also collected, and a sub-set of test-retest data. Th…
A new questionnaire specifically designed for patients affected by chronic obstructive pulmonary disease
2006
Summary The aim of this study was to develop a specific and valid questionnaire for Italian COPD patients, living on the north or the south of Italy—which are two culturally distinct areas. The project consisted in three steps: (1) initial item set generation to identify items relevant to both genders, all ages and both regions; (2) item reduction including tests of regional specificity; (3) tests of internal validity using item-response theory using Rasch one-parameter modelling. Ninty-six COPD patients (mean aged 69 yr; 78 Male) completed the original set of 124 items of the Italian Health Status Questionnaire (IHSQ). Item reduction was carried out using an established standardised approa…
Structural Validity of the Foot and Ankle Outcome Score for Orthopaedic Pathologies with Rasch Measurement Theory
2022
Publisher Copyright: © 2021 The Authors A B S T R A C T Background: The Foot and Ankle Outcome Score (FAOS) is one of the most frequently used patient reported outcome measures for foot and ankle conditions. The aim is to test the structural validity of the Finnish version of the FAOS using Rasch Measurement Theory. Methods: FAOS scores were obtained from 218 consecutive patients who received operative treatment for foot and ankle conditions. The FAOS data were fitted into the Rasch model and person separation index (PSI) calculated. Results: All the five subscales provided good coverage and targeting. Three subscales presented unidimensional structure. Thirty-eight of the 42 items had orde…
INTERPRETING LARGE SCALE NATIONAL LEVEL ASSESSMENT DATA IN MATHEMATICS BY USING RASCH ANALYSIS
2020
Latvia is undergoing a nation-wide curriculum reform in general education, with an aim to help students to develop 21st century skills. In order to successfully implement reform, not only teacher performance in the classroom is important, but also the transformation of the school culture is of high priority. One of the key dimensions that is characteristic for a school as learning organization culture is whether it has data-driven culture and is using data on continuous basis to improve student achievement. Large scale national level assessment data is used for many different purposes, however, this data only rarely is recognised as useful data source for planning actions to improve student…
Translation, Adaption, and Psychometric Testing of the Myanmar Version of the Medical Outcomes Study Social Support Survey for People Living With HIV…
2021
Introduction: Valid and reliable instruments are crucial for measuring perceived social support among people living with HIV (PLHIV). We aimed to investigate the psychometric properties of the English version of the 19-item Medical Outcomes Study Social Support Survey (MOS-SSS) adapted for PLHIV in Myanmar.Methods: Based on a standard cross-cultural procedure, we adapted the MOS-SSS and formed a Myanmar version of the scale (MOS-SSS-M), and then tested its validity and reliability. A sample of 250 eligible PLHIV was collected from a closed Facebook group that included more than 10,000 Myanmars, most of whom were PLHIV.Results: The MOS-SSS-M achieved a Cronbach’s α of 0.82–0.95. Confirmatory…
Do personal characteristics affect the Rasch measures of perceived physical risk? A quantile regression approach
2012
This paper focuses on the measurement of the perception of healthy risk according to personal characteristics. The Physical Risk Assessment Inventory was adopted as measurement tool and it was administered to 551 students enrolled in the first and in the fifth classes of some high schools of Palermo. The analysis of the determinants of the perceived risk is based on its quantitative measures. Therefore the analysis has been developed into two tracks. First track is devoted to obtain a quantitative measure of the perceived risk: an Extended Logistic Rasch Model was used considering separately males and females. Results highlight the different perception of risk between males and females, alt…
Rasch Analysis of the Japanese Version of Teacher Efficacy for Inclusive Practices Scale: Scale Unidimensionality
2020
This study aimed to examine the construct validity of the Japanese version of the Teacher Efficacy for Inclusive Practices (TEIP) scale. The sample consisted of 250 teachers in Japan. Rasch analysis was used to examine the psychometric properties of the scale. Results did not support the 18-item Japanese version of the TEIP scale as a unidimensional scale for measuring TEIP. However, they do support the final 14-item Japanese version of the TEIP scale as a unidimensional scale for measuring TEIP. Four items were removed from the original 18-item scale (items 12, 8, 5, and 3) for violation of the local independency assumption. No item with differential item functioning (DIF) was detected. On…
Modeling Ordinal Item Responses via Binary GLMMs and Alternative Link Functions: An Application to Measurement of a Perceived Service Quality
2010
Evaluation of a service on the basis of consumer opinion is a widespread practice in many fields. The assessment of perceived quality [7] of a service is generally carried out through administration of a questionnaire, composed of several items with responses posed on an ordinal scale, whereby each item represents an important feature of the evaluated service [3, 7]. In this context, the aim is to evaluate something similar to the external effectiveness, that is the part of efficacy related to the satisfaction expressed by the service users for the provided service. A particular and important example of service users is represented by students’ responses measuring the perceived quality of s…
La soddisfazione degli utenti interni delle aziende ospedaliere: considerazioni su uno strumento di misura
2003
The paper proposes the application of two different methodologies, based on the Traditional Test Theory (TTT) and on the Modern Test Theory (IRT), to select the items of a questionnaire administered in the year 2000 to the personnel of the Hospital Firm “Careggi” in Florence, in order to analyse the satisfaction of “internal consumers”. Such methodologies provide very different results, depending on the assumptions of the different models used.
Studiare il bullismo nelle scuole. Metodi e strumenti per rilevare gli atteggiamenti degli insegnanti
2021
Lo studio degli atteggiamenti pone due problemi di fondo dai quali non si può prescindere. Il primo è di natura epistemologica e riguarda la definizione stessa dell'oggetto di studio e la sua osservabilità. L'atteggiamento, proprio per la sua natura di "costrutto ipotetico", di variabile "interveniente" o "di mediazione", di variabile "latente", non è direttamente osservabile ed è, in potenza, inferibile esclusivamente da un'espressione o da un comportamento manifesto, ossia si osserva a un livello più specifico per cogliere empiricamente un oggetto collocato a un livello di maggiore generalità. Il secondo è di natura metodologica ed è relativo ai nodi critici che caratterizzano la rilevazi…
