Translation, cross-cultural adaptation, and validation of a Gujarati version of a theory of planned behavior questionnaire that assesses walking treatment beliefs in people with intermittent claudication.

BACKGROUND: Walking as a treatment is recommended for people with intermittent claudication (IC), but participation tends to be poor. Walking treatment beliefs, as defined by the Theory of Planned Behaviour (TPB) are associated with walking behavior, so assessing and designing interventions targeting walking treatment beliefs are crucial. To assess walking treatment beliefs in people with IC in Gujarat, a translated, culturally adapted questionnaire that assesses the four TPB constructs (attitude, subjective normative beliefs, perceived behavioral control beliefs, and intention to walk) is required. AIM: To translate and cross-culturally assess the content validity and face validity of a Gujarati version of a TPB questionnaire that assesses walking treatment beliefs. MATERIALS AND METHODS: A forward-backward translation of the 12-item TPB questionnaire was applied using a standardized approach. The translated versions were compared with the original questionnaire, and ten experts, rated each item according to: clarity, semantic, appropriateness, and cultural relevance. Content Validity Index (CVI), item level content validity (I-CVI), Scale -content validity index (S-CVI/Ave), and universal agreement (UA) were computed to summarize the overall content validity of the questionnaire as well as a proportion of agreement with content experts. Face validity was assessed using a think-aloud approach with ten patients with IC. This cognitive interviewing approach (think-aloud approach) asked participants to describe their thoughts whilst completing the questionnaire. Responses were analyzed thematically. RESULTS: There was complete agreement between experts for 9/12 items (I-CVI=1.00), leading to an overall agreement (S-CVI/Ave) of 0.98. For face validation, at least 50% of the participants had no significant problems with any question in the questionnaire. Most problems participants encountered were straightforward, such as re-reading some questions or considering the questions carefully before answering. CONCLUSION: The Gujarati TPB questionnaire had excellent content validity and was comprehensible and answerable by the majority of our participants with IC and, therefore, had good face validity; this will enable walking treatment beliefs to be assessed in people with IC.

Gujarati translation, validity and reliability of Walking Impairment Questionnaire in people with intermittent claudication due to peripheral artery disease.

INTRODUCTION: The Walking Impairment Questionnaire (WIQ) is a common and easy-to-use assessment of walking incapacity in people with claudication due to peripheral artery disease (PAD). It has four subscales: pain severity, walking distance, walking speed, and ability to climb stairs. It has not been translated into Gujarati, which limits its use in Indian subjects. AIM: This study aims to translate and assess the validity and reliability of a Gujarati version of WIQ. MATERIALS AND METHODS: This study had three phases: 1. Forward and backward translation and Cultural adaptation of WIQ into the Gujarati language by two independent translators, 2. Face and content validation by six clinical reviewers and 10 participants with PAD and Type II diabetes, 3. Concurrent and construct validity, test-retest reliability, and internal consistency of Gujarati, the WIQ was assessed on 160 participants with PAD and Type II diabetes who had a mean Ankle Brachial Index (standard deviation) <0.40 (0.1). The concurrent and construct validity of the WIQ was analyzed by correlating the WIQ distance and speed score with 6-minute walk distance (6MWD) and speed and WIQ total score with the Medical Outcome Study Questionnaire Short Form 36 (SF-36) score using Pearson's correlation coefficient. Test-retest reliability was analyzed using an intraclass correlation coefficient (ICC) with a seven-day interval between two questionnaire applications. Internal consistency of the total WIQ score was determined using Cronbach's alpha. RESULTS: Following translation, the Gujarati WIQ was considered acceptable and understandable by people with PAD. There was excellent correlation between the WIQ distance score and 6-minute walk test distance (r = 0.95, P < .05)) , the WIQ speed score and 6-minute walk test speed score (r = 0.89, P < .05)) and the Gujarati WIQ total score and total score of physical functioning domain of SF- 36 (r = 0.99, P < .05). There was excellent test-retest reliability over 7 days for total WIQ score (ICC = 0.94). The Cronbach's alpha for internal consistency of 0.97 for total WIQ score were excellent. This demonstrates the sufficient homogeneity of the total questionnaire. CONCLUSION: The Gujarati version of the WIQ is reliable and valid and can be used to assess self-reported walking impairment in Gujarati-speaking people with PAD and Type II Diabetes.

Inequity in exercise-based interventions for adults with rheumatoid arthritis: a systematic review.

Objectives: This systematic review describes the extent to which PROGRESS-Plus equity factors were considered in the eligibility criteria of trials of exercise interventions for adults with RA. Methods: Electronic databases were searched for published (Cinahl, Embase, Medline, Physiotherapy Evidence Database), unpublished (Opengrey) and registered ongoing (International Standard Randomized Controlled Trial Number registry) randomized controlled trials (RCTs) of exercise interventions for adults with RA. Two authors independently performed study selection and quality assessment (Cochrane risk of bias tool). Results: A total of 9696 records were identified. After screening, 50 trials were included. All trials had either some concerns or high risk of bias and reported at least one PROGRESS-Plus equity factor within the eligibility criteria; this included place of residence, personal characteristics (age and disability), language, sex, social capital, time-dependent factors or features of relationship factors. Where reported, this equated to exclusion of 457 of 1337 potential participants (34%) based on equity factors. Conclusion: This review identified the exclusion of potential participants within exercise-based interventions for people with RA based on equity factors that might affect health-care opportunities and outcomes. This limits the generalizability of results, and yet this evidence is used to inform management and service design. Trials need to optimize participation, particularly for people with cardiovascular conditions, older adults and those with cognitive impairments. Reasons for exclusions need to be justified. Further research needs to address health inequalities to improve treatment accessibility and the generalizability of research findings. PROSPERO registration: CRD42021260941.

Inequity in exercise-based interventions for adults with intermittent claudication due to peripheral arterial disease: a systematic review.

PURPOSE: To determine the equity in access to trials of exercise interventions for adults with intermittent claudication due to peripheral arterial disease. METHODS: Systematic electronic database searches of MEDLINE, Embase, CINAHL, Cochrane Central Register of Controlled Clinical Trials, PEDRO, Opengrey, ISRCTN and ClinincalTrials.gov for randomised controlled trials of exercise interventions for adults with intermittent claudication were conducted. Data extraction was informed by Cochrane's PROGRESS-Plus framework. RESULTS: Searches identified 6412 records. Following the screening of 262 full texts, 49 trials including 3695 participants were included. All trials excluded potential participants on at least one equity factor. This comprised place of residence, language, sex, personal characteristics (e.g., age and disability), features of relationships (e.g., familial risk factors) and time-dependent factors, (e.g., time since revascularisation). Overall, 1839 of 7567 potential participants (24.3%) were excluded based on equity factors. Disability was the most frequently reported factor for exclusions. CONCLUSION: Trialists endeavour to enrol a representative sample in exercise trials whilst preserving the safety profile of the intervention. This review highlights that these efforts can inadvertently lead to inequities in access as all trials excluded potential participants on at least one equity factor. Future exercise trials should optimise participation to maximise generalisability of findings. PROSPERO registration no.
