Addressing data deficiencies in assistive technology by using statistical matching methodology: a case study from Malawi.

PURPOSE: To address the data gap on efforts to assess use of assistive technology among children with disability in sub-Saharan Africa. Contribute towards efforts examining access to assistive technologies in sub-Saharan Africa. MATERIALS AND METHODS: The paper uses data from the 2017 survey on Living conditions among persons with disabilities in Malawi and the 2015-16 Malawi Demographic and Health survey to address the objective of the study. The two datasets were statistically matched through random hot deck technique, by integrating the two datasets using randomly selected units from a subset of all available data donors. RESULTS: Results indicate that statistical matching technique produces a composite dataset with an uncertainty value of 2.2%. An accuracy assessment test of the technique also indicates that the marginal distribution of use of assistive technology in the composite dataset is similar to that of the donor dataset with an Overlap index value of close to 1 (Overlap = 0.997). CONCLUSIONS: The statistical matching procedure does enable generation of good data in data constrained contexts. In the current study, this approach enabled measurement of access to assistive products among children with disabilities, in situations where the variables of interest have not been jointly observed. Such a technique can be valuable in mining secondary data, the collection of which may have been funded from different sources and for different purposes. This is of significance for the efficient use of current and future data sets, allowing new questions to be asked and addressed by locally based researchers in poor settings. Implications for RehabilitationIn resource-poor settings, the technique of statistical matching can be used to examine factors that predict the use of assistive technology among persons with disabilities.The statistical matching technique is of significance for the efficient use of current and future datasets, allowing new questions to be asked and addressed by locally based researchers.

Socio-Demographic Factors Influencing the Use of Assistive Technology among Children with Disabilities in Malawi.

This paper aims to address the information gap on the influence of socio-demographic factors on access and utilization of Assistive Technology (AT) among children with disabilities in Malawi. Thus, it contributes towards the realization of the recommendations of the UN Convention on the Rights of Persons with disabilities and the development of a framework for creating an effective national AT policy. The paper used two statistically matched datasets, namely, the 2017 survey on Living conditions among persons with disabilities in Malawi and the 2015-16 Malawi Demographic and Health survey. Logistic regression and structural equation modeling techniques were utilized to assess the influence of socio-demographic factors on the use of AT among children with disabilities. The results indicate that there is a high level of unmet need for AT among young children aged 2 to 9 and those living in urban areas. The results further indicate that children with multiple disabilities have lower odds (OR = 0.924) of using AT for personal mobility compared to children with a single functional difficulty. These results entail that AT needs for children with multiple disabilities are not adequately addressed. Therefore, when developing policies on AT, younger children and those with multiple disabilities need to be specifically targeted.
