Psychometric validation of the Italian translation of the gastrointestinal symptom-rating scale and quality of life in reflux and dyspepsia questionn…
2007
Background: Symptoms of heartburn and their impact on health-related quality of life (HR-QOL) are often evaluated in clinical trials. When a questionnaire is translated into a new language, a linguistic validation is necessary but not sufficient unless the psychometric characteristics have been verified. Objective: To document the psychometric characteristics of the Italian translation of the Gastrointestinal Symptom-Rating Scale (GSRS) and Quality of Life in Reflux and Dyspepsia (QOLRAD) questionnaire. Patients and methods: 152 consecutive patients with symptoms of heartburn (mean ±SD age 46.5 ± 16.2 years; 40.1% males) completed the Italian translation of GSRS, the heartburn version of QO…
HepaDisk – A new quality of life questionnaire for HCV patients
2019
Abstract Background Since most patients with hepatitis C virus (HCV) infection now receive treatment irrespective of liver disease severity, special attention to patient quality of life (QoL), including psycho-social aspects, is required. No QoL questionnaire is specific for patients with HCV. Aims To develop and validate a short Italian questionnaire (HepaDisk) assessing the QoL of patients affected by HCV with intuitive graphic results that is understandable by patients and physicians. Methods A questionnaire, drafted by a steering committee, underwent a Delphi survey. A multicenter, observational study was conducted to validate the developed HepaDisk versus other tools (CLDQ-I, SF-36, WP…
Expression of clec9a in the oral cancer microenvironment. A preliminary immunohistochemical pilot study
2021
Background The search for treatments to improve cancer survival has led to the emergence of immunotherapy and the study of the tumour microenvironment existing in neoplasms. This preliminary study aims to understand the clinical and pathological relationship of clec9a expression in oral cancer and to explore survival models for future studies. Material and methods: Immunohistochemical study that included 26 patients with a diagnosis of oral squamous cell carcinoma (OSCC) in mobile tongue and floor of the mouth. Clinical and histopathological variables were recorded, and the biomarkers clec9a for dendritic cells and CD8 and CD4 for lymphocytes were used. Results Clec9a was expressed in 58% o…
Short Sexual Well-Being Scale – a cross-sectional validation among transgender and cisgender people
2020
BackgroundSexual well-being is often mistakenly operationalized simply as sexual satisfaction. The concept of sexual well-being has been often used as an umbrella term for positive aspects of sexuality, apart from its negative spheres. A new concept of sexual well-being was proposed in line with the World Health Organization (WHO) definition of sexual health. The definition tried to enrich the concept of sexual well-being, but it did not solve the problem of its operationalization. The aim of this study was to verify the psychometric properties of the new scale measuring the concept of sexual well-being.Participants and procedureTwo separate studies were conducted for the psychometric valid…
Selected psychometric aspects of the Polish version of the Liverpool Self-efficacy Scale
2020
BackgroundSelf-efficacy expresses the individual’s belief in their ability to take up and continue actions in order to achieve a particular result and cope with various life events. For people with multiple sclerosis (MS), self-efficacy is an im-portant resource because it affects how they adapt to the disease, and influences their motivation, health-related behavior and physical activity. It also has a great impact on their quality of life. Because of the lack of tools for meas-uring self-efficacy in Polish patients with multiple sclerosis, the goal of the current study was to develop a Polish language version of the Liverpool Self-efficacy Scale (LSES) and assess its validity and reliabil…
An Evaluation of the Belief in Science Scale
2019
The Belief in Science Scale (BISS) is a unidimensional measure that assesses the degree to which science is valued as a source of superior knowledge. Due to increased academic interest in the concept of belief in science, the BISS has emerged as an important measurement instrument. Noting an absence of validation evidence, the present paper, via two studies, evaluated the scale’s factorial structure. Both studies drew on data collected from previous research. Study 1 (N = 686), using parallel analysis and exploratory factor analysis, identified a unidimensional solution accounting for 56.43% of the observed variance. Study 2 (N = 535), using an independent sample, tested the unidimensional …
