Validation of a new questionnaire to assess the impact of Whiplash Associated Disorders: The Whiplash Activity and participation List (WAL)

The Sociodemographic Factors Related to Disability of Applicants of Welfare Benefits in Greece: A Cross-Sectional Survey Based on the World Health Organization Disability Assessment Schedule (WHODAS) 2.0

INTRODUCTION

The aim of the present study was to report on the prevalence of disability and its association with sociodemographic factors among welfare benefit applicants in Greece. The study also compared the disability scores between different health conditions using the WHODAS 2.0 (12-item version), a biopsychosocial-model-based measure.

METHODS

The Greek WHODAS 2.0, 12-item version, was administered by interview. A three-member medical committee assessed the medical records of the applicants and assigned a disability percentage based on the biomedical measure of disability percentage determination (Barema scale).

RESULTS

The majority of the participants were female (56.65%). Certain health conditions were presented more frequently among welfare benefit applicants (mental health disorders and neoplasms). The domains with the highest rate of difficulty were the "participation" and "life activities" domains. Significant differences were found between WHODAS 2.0 and Barema scores for all eight different health condition categories. The factorial ANOVA (8x2) showed a significant interaction effect between health condition category and gender with respect to the WHODAS 2.0 score (F = 19.033, p <.001, η2 = 0.13). The WHODAS 2.0 score was negatively correlated to gender, years of studies, and marital status and positively correlated to age, working status, and the Barema score. The results revealed that male participants with a partner who were younger, had more studies, were actively working, and had a lower Barema score would have lower WHODAS scores.

CONCLUSION

Sociodemographic characteristics of welfare benefit applicants are associated with disability levels based on WHODAS 2.0. Certain health conditions, like mental health or neuromusculoskeletal conditions, are associated with higher disability scores. There are differences between the biopsychosocial and the biomedical approaches to disability assessment. The implementation of WHODAS 2.0 may contribute to a better understanding of the lived experience of patients and is a feasible and efficient tool. Combining biomedical and biopsychosocial approaches may enhance the procedures of disability assessment and help in the development of policies that support people with disabilities.

Clinimetric Properties of Self-reported Disability Scales for Whiplash: A Systematic Review for the Whiplash Core Outcome Set (CATWAD)

OBJECTIVES

A core outcomes set (COS) for whiplash-associated disorders (WADs) has been proposed to improve consistency of outcome reporting in clinical trials. Patient-reported disability was one outcome of interest within this COS. The aim of this review was to identify the most suitable tools for measuring self-reported disability in WAD based on clinimetric performance.

METHODS

Database searches took place in 2 stages. The first identified outcome measures used to assess self-reported disability in WAD, and the second identified studies assessing the clinimetric properties of these outcome measures in WAD. Data on the study, population and outcome measure characteristics were extracted, along with clinimetric data. Quality and clinimetric performance were assessed in accordance with the Consensus-based Standards for the Selection of Health Status Measurement Instruments (COSMIN).

RESULTS

Of 19,663 records identified in stage 1 searches, 32 were retained following stage 2 searches and screening. Both the Whiplash Disability Questionnaire and Neck Disability Index performed well in reliability (intraclass correlation coefficient=0.84 to 0.98), construct validity (74% to 82% of hypotheses accepted), and responsiveness (majority of correlations in accordance with hypotheses). Both received Category B recommendations due to a lack of evidence for content validity.

DISCUSSION

This review identified the Neck Disability Index and Whiplash Disability Questionnaire as the most appropriate patient-reported outcome measures (PROMs) for assessing self-reported disability in WAD based on moderate to high-quality evidence for sufficient reliability, construct validity and responsiveness. However, the content validity of these PROMs has yet to be established in WAD, and until this is undertaken, it is not possible to recommend 1 PROM over the other for inclusion in the WAD COS.

The Bournemouth Questionnaire for Neck Pain: Cross-cultural Adaptation, Reliability, and Validity of the Turkish Version

OBJECTIVE

The aim of this study was first to translate and culturally adapt the BQN, and then to investigate the validity and reliability of the Turkish version of the BQN in Turkish individuals with chronic neck pain.

METHODS

The English version of the BQN was translated into Turkish with permission from its authors. That translation was assessed using 85 participants with a mean age of 46.75 years who had chronic neck pain. At the same time, the participants were assessed sociodemographically and with the Neck Disability Index (NDI) and the Neck Pain and Disability Scale (NPAD). A test-retest procedure was performed with 62 participants who underwent a second assessment with the BQN within 24 hours of the first assessment, to test its reliability.

RESULTS

Internal consistency was strong and all Cronbach alpha values were between 0.97 and 0.99. The BQN showed high test-retest reliability (intraclass correlation coefficient ˃ 0.92) for all domains. The total mean (± standard deviation) scores for the 3 questionnaires were as follows: BQN, 30.9 (± 11.18); NPAD, 48.16 (± 12.93); NDI, 17.85 (± 6.29). The results of the Turkish version of the BQN illustrated adequate external construct validity and sensitivity. A Turkish translation of the test has not previously been available for chronic pain.

CONCLUSION

The BQN was successfully translated and culturally adapted into Turkish. The reliability and validity were tested against the NPAD and the NDI. The Turkish version of the BQN is multidimensional, short, practical, and suitable for use with individuals with neck pain.
