Reliability, validity, and minimal clinically important differences for the Thai-version of the Aberdeen Varicose Vein Questionnaire (AVVQ-Thai) in patients with chronic venous disease.

Background: Patient-reported outcome measures (PROMs) are essential for assessing the health of patients with chronic venous disease (CVD). Therefore, we aimed to translate the Aberdeen Varicose Vein Questionnaire into Thai language (AVVQ-Thai) and evaluate its reliability and validity. Minimal clinically important differences (MCID) of the AVVQ-Thai also be estimated.

Use of EQ-5D-5L for Assessing Patient-Reported Outcomes in a National Register for Specialized Rehabilitation.

Objective: To compare problems reported on EQ-5D-5L dimensions, index, and EQ visual analog scale (VAS) scores in patients receiving specialized rehabilitation in Norway with general population norms.

Design: Multicenter observational study.

Setting: Five specialist rehabilitation facilities participating in a national rehabilitation register between March 11, 2020, and April 20, 2022.

Evaluation of the Norwegian version of the Dyspnoea-12 questionnaire in patients with COPD.

Background: The Dyspnoea-12 (D-12) questionnaire is widely used and tested in patients with breathing difficulties. The objective of this study was to translate and undertake the first evaluation of the measurement properties of the Norwegian version of the D-12 in patients with chronic obstructive pulmonary disease (COPD) attending a 4-week inpatient pulmonary rehabilitation programme.

Methods: Confirmatory factor analysis was used to assess structural validity.

Norwegian population norms for the EQ-5D-5L: results from a general population survey.

Purpose: To provide the first Norwegian EQ-5D-5L and EQ VAS population norms for the adult general population.

Methods: Postal survey of a random sample of 12,790 Norwegians identified through the National Registry of the Norwegian Tax Administration. Norms, weighted for Norwegian general population characteristics, are shown for the five EQ-5D-5L dimensions, EQ-5D index, and EQ VAS scores for seven age categories, females, males, and education level.

The Nordic Patient Experiences Questionnaire (NORPEQ): cross-national comparison of data quality, internal consistency and validity in four Nordic countries.

Objectives: To evaluate the Nordic Patient Experiences Questionnaire (NORPEQ) for data quality, reliability and validity following surveys of patients in Finland, Norway, Sweden and the Faroe Islands. DESIGN, METHODS AND PARTICIPANTS: The NORPEQ was mailed to 500 patients randomly selected after receiving inpatient treatment in Finland, Norway and Sweden. The NORPEQ was also included in a national survey in Norway and in the Faroe Islands.

Assessing burden of illness following acute deep vein thrombosis: data quality, reliability and validity of the Norwegian version of VEINES-QOL/Sym, a disease-specific questionnaire.

The data quality, reliability and validity of the Norwegian version of VEINES-QOL/Sym were assessed in 74 patients with deep vein thrombosis (DVT). This patient-reported questionnaire produces two scale scores of venous disease-specific quality of life and venous symptoms. Items had low levels of missing data.
