Cross-cultural adaptation, validity and reliability of the Persian version of Fremantle Knee Awareness Questionnaire

Translation, cross-cultural adaptation, and analysis of the measurement properties of the Fremantle Knee Awareness Questionnaire (FreKAQ) into Brazilian Portuguese for individuals with knee osteoarthritis

OBJECTIVE

This study aimed to translate and cross-culturally adapt the Fremantle Knee Awareness Questionnaire (FreKAQ) into Brazilian Portuguese and evaluate the measurement properties, including internal consistency, construct validity, reliability, and ceiling and floor effects in individuals with knee osteoarthritis (KOA).

METHODS

Translation, cross-cultural adaptation, and analysis of measurement properties were performed according to international recommendations. One hundred thirty-four individuals diagnosed with KOA participated in the study. Of these, 30 participated in the validation process of the pre-final version of the FreKAQ. One hundred four were evaluated with the FreKAQ, the Numeric Pain Rating Scale (NPRS), the Pain Catastrophizing Scale (PCS), the International Knee Documentation Committee (IKDC), and the 36-item short-form survey (SF-36). The construct validity was tested using Spearman's correlation coefficient, and ceiling and floor effects were calculated. A subsample of 54 participants participated in the reproducibility assessment. Internal consistency was calculated using Cronbach's alpha. Reproducibility was assessed using the test-retest model using the intraclass correlation coefficient (ICC), standard error of measurement (SEM), and minimum detectable change (MDC).

RESULTS

the FreKAQ showed a favorable correlation with the construct's intensity and catastrophizing related to pain and activities of daily living (p < 0.01). It also had the functional capacity, pain, social aspects, and emotional aspects of the SF-36 (p < 0.05). Additionally, it presented excellent ICC (0.91) and adequate internal consistency (0.91) with the SEM and MDC scores, respectively, 2.86 and 7.94. There were no ceiling or floor effects.

CONCLUSION

The FreKAQ showed adequate measurement properties in individuals with KOA, indicating its use as an evaluative measure of body perception of the knee.

Self-reported questionnaires assessing body perception disturbances in adults with chronic non-cancer pain: a scoping review

Introduction

Body perception disturbances (BPD) are well documented in certain chronic pain populations [e.g., complex regional pain syndrome (CRPS)], while being far less studied in chronic pain as a general condition. The aims of this scoping review are to identify the self-reported questionnaires used to assess BPD in individuals with chronic non-cancer pain and to refine the definition of the BPD construct as used in these questionnaires.

Methods

A search strategy focusing on the concepts of "chronic pain", "body perception" and "questionnaire" was used across four databases. Each record was screened for eligibility by two independent reviewers, and data extraction was performed by one reviewer and validated by a second reviewer.

Results

Eighty-seven studies were included, comprising 18 different questionnaires-either directly related to BPD or containing relevant items. The three most commonly used questionnaires were the Bath Body Perception Disturbance Scale, the Fremantle Back Awareness Questionnaire, and the Neurobehavioral Questionnaire. Appraisal of the construct derived from the questionnaire items identified five main facets: size, shape, cognitive neglect-like symptoms, proprioceptive awareness, and agency, along with 11 other less frequently addressed facets. The most represented clinical populations were CRPS (40 studies) and chronic low-back pain (20 studies).

Discussion

A variety of self-reported questionnaires are available to assess BPD, but most are diagnosis- or body-region specific. To better assess BPD in individuals with chronic non-cancer pain, a consensus on the general definition and the key facets of the construct is needed.

Reliability and validity of the Chinese version of the instrument of health literacy competencies for health professionals

AIMS

This study aimed to evaluate the reliability and validity of the Chinese version of an instrument of health literacy competencies for health professionals.

DESIGN

This study utilized a cross-sectional design.

METHODS

Authorization was obtained from the authors of the original scale to translate the scale and perform cross-cultural debugging. From August 2020 to November 2020, 573 health professionals were randomly selected from primary, secondary and tertiary hospitals in Huzhou to examine the reliability and validity of the Chinese version of an instrument of health literacy competencies for health professionals.

RESULTS

The Chinese version of the scale contains 49 items. The internal consistency Cronbach's α was 0.958 for the total scale and 0.791-0.956 for each dimension. The test-retest reliability was 0.973. Confirmatory factor analysis showed that the fitness degree of the model is good (χ² /df = 1.347, IFI = 0.924, TLI = 0.913, CFI = 0.922, GFI = 0.841, AGFI = 0.815, RMR = 0.011, RMSEA = 0.035).

CONCLUSION

The Chinese version of an instrument of health literacy competencies is reliable and valid, which is a credible and effective tool to assess the level of health literacy competencies in Chinese health professionals.

PATIENT OR PUBLIC CONTRIBUTION

Health professionals with good health literacy competencies can provide patient-specific treatment and guidance to promote healthy outcomes for patients.
