Background: The aim of this study was to estimate the prevalence of disability and its associated risk factors among adults aged 18 years and over in Bogra district, Bangladesh. Methods: The Rapid Assessment of Disability (RAD) survey was conducted using probability-proportional-to-size sampling to select 66 clusters each with 50 people aged 18 years and older in 2010. Households within clusters were selected through compact segment sampling. Disability was identified based on the responses to the self-assessment of functioning section of the RAD questionnaire. Descriptive and multivariate logistic regression analyses were performed to model the associations between risk factors and disability status. Results: Of 1855 adults who participated in the study, 195 (10.5 %) had disability. Age and gender adjusted prevalence of disability in Bogra district was 8.9 % (95 % CI: 7.7, 10.3). The highest prevalence of functional limitation was related to psychological distress (4.7 %; 95 % CI: 3.8, 5.7) followed by vision (4.4 %; 95 % CI: 3.6, 5.4), and hearing (2.3 %; 95 % CI: 1.7, 3.0) difficulties. The adjusted odds of disability increased with age with approximately eight-fold increase from 2.9 % (95 % CI: 1.6, 5.1) in 18-24 years to 24.5 % (95 % CI: 20.2, 29.4) in 55 years and above. People with poor socio-economic status (OR 1.90; 95 % CI: 1.1, 3.3) and who were unemployed (OR = 4.6; 95 % CI: 1.8, 11.6) were more like to have disability compared to the higher socio-economic status and those who have an occupation respectively. Conclusions: There is a significant need for promoting programs for health, well-being, and rehabilitation, and policies specifically targeting the older population, women, unemployed and poor people in Bangladesh.

Background: The Rapid Assessment of Disability (RAD) questionnaire measures the magnitude and impact of disability and aims to inform the design of disability inclusive development programs. This paper reports the psychometric evaluation of the RAD. Methods: The initial version of the RAD comprised five sections: 1) demographics, 2) functioning, 3) rights awareness, 4) well-being, and 5) access to the community. Item functioning and construct validity were assessed in a population-based study in Bangladesh. Data were analysed using descriptive statistics (sections 2 and 5) and Rasch modelling (sections 3 and 4). A subsequent case-control study in Fiji tested the refined questionnaire in a cross-cultural setting and assessed the sensitivity and specificity of the RAD section 2 to identify people with disability. Results: 2,057 adults took part in the study (1,855 in Bangladesh and 202 in Fiji). The prevalence of disability estimated using RAD section 2 in Bangladesh was 10.5% (95% CI 8.8-12.2), with satisfactory sensitivity and specificity (62.4% and 81.2%, respectively). Section 3 exhibited multidimensionality and poor differentiation between levels of rights awareness in both Bangladesh (person separation index [PSI] = 0.71) and Fiji (PSI = 0.0), and was unable to distinguish between people with and without disability (Bangladesh p = 0.786, Fiji p = 0.403). This section was subsequently removed from the questionnaire pending re-development. Section 4 had good ability to differentiate between levels of well-being (PSI = 0.82). In both countries, people with disability had significantly worse well-being scores than people without disability (p < 0.001) and also access to all sectors of community except legal assistance, drinking water and toilets (p < 0.001). Conclusions: Filed-testing in Bangladesh and Fiji confirmed the psychometric robustness of functioning, well-being, and community access sections of the RAD. Information from the questionnaire can be used to inform and evaluate disability inclusive development programs. [ABSTRACT FROM AUTHOR]

Purpose: The Rapid Assessment of Disability (RAD) questionnaire was developed to provide governments and development agencies with an appropriate instrument to determine the prevalence of people with disability within their target populations, and to design and evaluate the effectiveness of disability inclusive activities in addressing their priorities and needs. Method: The RAD questionnaire was developed using two conceptual frameworks: the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD), and the International Classification of Functioning, Disability and Health (ICF). Existing instruments were reviewed to inform the structure and content of the RAD questionnaire. The RAD questionnaire that was developed for field testing in Bangladesh comprised both a household questionnaire and a questionnaire for individuals within each household, with 5 sections: 1) Demographic information, 2) Assessment of functioning, 3) Awareness of rights of people with disability, 4) Well-being and quality of life, 5) Participation in the community. Prior to field-testing the RAD questionnaire in Bangladesh, a qualitative study was conducted to ensure the relevance of the questionnaire in the context of a developing country. In-depth interviews with 9 people with disability and a focus group of 8 parents of children with disability were conducted in Dhaka, Bangladesh. Results:Qualitative findings highlighted factors relevant to the lives of people with disability in Bangladesh, including discrepancies between the awareness and attainment of rights for people with disability, the wellbeing of people with disability and their families, as well as numerous barriers to full participation in their community. While the findings confirmed that the design and content of the questionnaire reflected all these aspects, some changes were made to the items in the questionnaire to ensure that it reflected the views of people with disability from the context of a developing country. Conclusion and Implications: This qualitative study was an important step in the development of the RAD questionnaire as it helped to achieve its aim -namely, to establish the prevalence of disability and to assist in the design and evaluation of disability inclusive interventions in the setting of a developing country.
