Background: As the use of everyday technology is increasingly important for participation in daily activities, more in-depth knowledge of everyday technology use in relation to diagnosis and gender is needed. The purpose of this study was to investigate the stability of the perceived challenge of a variety of everyday technologies across different samples of varying diagnoses including both males and females.

 

Methods: This cross-sectional study used 643 data records from clinical and research samples, including persons with dementia or related disorders, acquired brain injury, intellectual disability, various mental or medical disorders, and adults without known diagnoses. The Everyday Technology Use Questionnaire, comprising 93 everyday technology artifacts and services (items) measuring the level of everyday technology challenge and relevance of and perceived ability to use these was used for data gathering. A two-faceted Rasch model in combination with differential item functioning (DIF) analyses were used for comparing item hierarchies across samples.

 

Results: Only three items (3.2%) demonstrated a clinically relevant DIF by gender, and nine items (9.7%) by diagnosis.

 

Discussion: The findings support a stable hierarchy of everyday technology challenge in home and community that can facilitate planning of an accessible and inclusive society from a technological departure point

The intersection of disability and food security: Perspectives of health and humanitarian aid workers

QUARMBY, Candice A.
PILLAY, Mershen

Expand view

Background: Most people with disabilities the world over can be found in the Majority (or ‘economically developing’) World. This is also where most of the world’s hungry and malnourished are found. We argue that the intersectionality between disability and nutrition may best be understood through a food security framework, and we position all people living with disability, including those experiencing feeding and swallowing disabilities, as at risk for food insecurity, especially those living in humanitarian emergency contexts.

 

Objectives: This study aimed to explore and describe the knowledge and experience of humanitarian aid workers (HAWs) and health care professionals (HCPs) in food assistance contexts with regard to the nutrition and food security of people living with disabilities.

 

Method: In this exploratory, descriptive study, 16 participants with experience in sub-Saharan Africa and Southern Asia participated in an online survey. Three survey participants with extensive experience were also interviewed. Data analysis involved descriptive statistics and thematic content analysis.

 

Results: Results revealed that participants had generally low levels of exposure to and experience with disability, including swallowing and feeding disorders.

 

Conclusions: Reduced knowledge of HAWs and HCPs regarding disability and the lack of professionals such as speech–language therapists, who manage disability-specific issues such as feeding and swallowing disorders, may affect the food security of people living with disabilities in food assistance contexts.

Hearing children of Deaf parents: Gender and birth order in the delegation of the interpreter role in culturally Deaf families

MOROE, Nomfundo F.
ANDRADE, Victor de
2018

Expand view

Background: Culturally, hearing children born to Deaf parents may have to mediate two different positions within the hearing and Deaf cultures. However, there appears to be little written about the experiences of hearing children born to Deaf parents in the South African context.

 

Objective: This study sought to investigate the roles of children of Deaf adults (CODAs) as interpreters in Deaf-parented families, more specifically, the influence of gender and birth order in language brokering.

 

Method: Two male and eight female participants between the ages of 21 and 40 years were recruited through purposive and snowball sampling strategies. A qualitative design was employed and data were collected using a semi-structured, open-ended interview format. Themes which emerged were analysed using thematic analysis.

 

Results: The findings indicated that there was no formal assignment of the interpreter role; however, female children tended to assume the role of interpreter more often than the male children. Also, it appeared as though the older children shifted the responsibility for interpreting to younger siblings. The participants in this study indicated that they interpreted in situations where they felt they were not developmentally or emotionally ready, or in situations which they felt were better suited for older siblings or for siblings of another gender.

 

Conclusion: This study highlights a need for the formalisation of interpreting services for Deaf people in South Africa in the form of professional interpreters rather than the reliance on hearing children as interpreters in order to mediate between Deaf and hearing cultures.

Purpose: To (A) develop a method for measuring compliance with standards, and (B) implementation of the method in 12 rehabilitation centers in six low and middle-income countries (LMICs).

 

Methods: In part A, existing standards were compiled and operationalized into scores, organized into 5 ‘scorecards’ and 15 ‘sub-scorecards’, then tested and refined in an iterative process. In part B, 12 rehabilitation centers in 6 countries implemented the standards using the new method, revealing relative performance between centers, and across different standards. Internal consistency of scores within domains was computed using Chronbach’s alpha.

 

Results: A standardized method for scoring compliance with standards for rehabilitation was developed. The method evaluated compliance with standards in five domains of practice: user focused approach, service outputs, finances, staff, and general management. Multiple standards within domains were strongly related, with Chronbach’s alpha >0.80 for all but the equipment and supplies domain. Overall, in the 12 rehabilitation centers examined, 36% of standards were met or exceeded. Compliance within each scoring domain was 56% (user-focused approach), 38% (service outputs), 27% (financial management), 30% (staff management), and 33% (general management). Two out of 12 (17%) of centers met more than two-thirds of the standards, 3 (25%) met more than one-third of standards, while the remaining 7 (58%) met less than one-third of standards.

 

Conclusions: A new, standardized method for measuring performance of rehabilitation services in LMICs was developed. The method examines standards in five rehabilitation practice domains, and can be used to understand barriers to quality performance, particularly in resource-constrained settings. Implementation of the method demonstrated that current compliance with standards is modest. Ongoing interest in new standards for rehabilitation practice should be accompanied by measures to ensure they are used to strengthen quality in an emerging rehabilitation sector.

Background: Inclusive education requires that the framework within which education is delivered should be broad enough to accommodate equally the needs and circumstances of every learner in the society. This includes learners with disabilities like dyslexia who have been excluded from the formal education system. This article reports the findings of a qualitative study that explored and described the dyslexic learners’ experiences with their peers and teachers in special and public schools in North-West Province of South Africa.


Methods: The study adopted a qualitative methodology and used a phenomenology research design. The sample was purposively selected and comprised nine dyslexic learners. All the learners were in public schools previously and were later moved to a special school after being diagnosed as dyslexic. The participants were aged 9–12 years. The researchers conducted one-on-one interviews with the participants and content-analysed the data.


Findings: The findings revealed that in public schools the dyslexic learners were exposed to ill-treatment by other learners who despised, ridiculed, bullied and undermined them. The findings further revealed that teachers in public schools were not patient with dyslexic learners, did not give them extra attention and that some teachers used negative comments that embarrassed them.


Conclusion: The article spells out the barriers experienced by dyslexic learners in public schools and also recommends training of teachers so that they know how to deal with dyslexic learners, thereby eliminating the barriers. The study further recommended awareness campaigns among the student body about dyslexia.

‘How deep are your pockets?’ Autoethnographic reflections on the cost of raising a child with autism

Background: In this article, we reflected on our experience of the cost of parenting a child with autism, including our ongoing search for educational and therapeutic intervention.


Objectives: We aimed to give an academic insight into the state of autism education and care in South Africa as seen by us, with special attention to its cost and sustainability.


Methods: Using evocative autoethnography as storied scholarship together with critical autism studies, we reflected on stories of the past 5 years since our son’s diagnosis.


Results: Our experiences agree with international studies that establish autism as the most expensive disability. In addition to the high costs of diagnosis, existing intervention and support approaches are unaffordable for the majority of South Africans. We recommend that teachers should be trained to participate in early screening and diagnosis, as well as co-therapists, to strengthen the implementation of inclusive education.


Conclusion: The kind of autism intervention currently offered in South Africa is financially and socially unsustainable. Instead of positioning autism as an individual or family dilemma, it should be addressed as an educational and societal issue. Future research should explore cost-effective options for a developing country context, while promoting best practice within inclusive settings.

‘I felt pain. Deep pain…’: Experiences of primary caregivers of stroke survivors with aphasia in a South African township

MASUKU, Khetsiwe P.

Background: Aphasia is an acquired impairment in language and in the cognitive processes that underlie language. Aphasia affects the quality of life of the person with aphasia (PWA) and his or her families in various ways in diverse contexts and cultures. It is therefore important that speech language therapists understand how different contextual and cultural factors may mediate experiences.


Purpose: The aim of the study was to describe the caregiving experience of female caregivers of PWA residing in Tembisa, a township situated in the east of Johannesburg.


Method: Qualitative, semi-structured interviews were conducted with primary caregivers of PWA. Purposive sampling was used to recruit 14 primary caregivers of PWA who were daughters, daughters-in-law or wives of the PWA. The interviews were conducted in participants’ first language and analysed by the researcher, who is proficient in isiZulu. Data were analysed according to the principles of thematic analysis.


Results: Findings indicated that caregivers are unfamiliar with aphasia and the support available to them. Participants experienced frustration and found communication to be challenging owing to their lack of communication strategies. The participants’ experiences reflected their context-specific experiences, such as feminisation of caregiving, barriers to healthcare, the influence of low health literacy and contextual perspectives on stroke and aphasia.


Conclusions: Contextual factors of caregivers in Tembisa have an influence on the experiences between caregivers and PWA, the feelings of individuals and families and health-seeking behaviours of individuals and families.

Background: Workforce factors present a significant barrier to the development of rehabilitation services for people with communication disabilities in sub-Saharan Africa (SSA). Exploring how the work of speech and language therapists (SLTs) in the region is organised and delivered can provide insight into existing services, areas for future workforce development and improved rehabilitation access for people with communication disability.


Objectives: This paper describes the employment and service provision patterns and work roles of a sample of SLTs in SSA.


Method: A broad, purpose-designed, mixed-methods survey was designed to collect data from SLTs living in Anglophone countries of SSA. Descriptive statistics and qualitative content analysis were undertaken. This paper reports on a subset of data from the wider survey.


Results: A description of the employment and work roles of the 33 respondents to the survey and characteristics of their service users is presented. SLTs were commonly employed within private and not-for-profit sectors and frequently worked in temporary jobs. SLTs engaged in a range of work roles, including capacity building and training others. Services were provided by SLTs across age ranges, health conditions and settings, with paediatric, urban services commonly reported. Costs for service users and urban-centred services give indications of barriers to service access.


Conclusion: Knowledge of the way in which speech and language therapy services are organised and provided has the potential to shape the development of communication disability rehabilitation in SSA. This research has identified a range of issues requiring consideration as the profession develops and grows.

Part 2: The feasibility of utilising photovoice method and the World Health Organization Quality of Life instrument in evaluating the Community-Based Rehabilitation programme in Namibia: A pilot study

Background: Evaluation of Community-Based Rehabilitation (CBR) programmes in Namibia has been primarily quantitative, focusing mainly on outputs, including numbers of persons with disabilities served, referrals made and activities implemented. Little or no evidence is available on experiences and quality of life of persons with disabilities, despite the CBR programme being operational for more than 20 years. The 2011 World Report on Disability recommended the use of appropriate tools to fill the research gap by integrating the experiences of persons with disabilities and their quality of life.

 

Objectives: The overall objective of the larger cohort study is to develop a monitoring and evaluation tool that can measure and integrate the experiences of persons with disabilities and their quality of life within the context of the CBR Programme in Namibia.

 

Method: An adapted photovoice process was conducted with six purposively selected participants over a period of 1 month. The World Health Organization Community-Based Rehabilitation (WHO CBR) Matrix was used to identify the themes and subthemes. Participants were requested to complete the World Health Organization Quality of Life (abbreviated version) (WHOQOL-BREF) instrument at the end of the photovoice process to determine their quality of life.

 

Results: Administering the WHOQOL-BREF instrument at the end of the photovoice process measured both the quality of life of persons with disabilities and at the same time indicated the convergence and divergence in the two data collection methods. The study demonstrated a stronger convergence than divergence of the two methods. A feasibility criterion was mapped for future studies.

 

Conclusion: This study demonstrated that photovoice is a flexible method that can be used with a variety of disabilities and has the potential of being combined with the WHOQOL-BREF assessment form. A larger cohort study may consider implementing photovoice and WHOQOL-BREF on multiple study sites and be able to compare results, considering geographical and demographic variables. The feasibility of utilising each method alone and in combination offered valuable insights on future conceptual framing of CBR programme evaluation. This conceptual framing will allow CBR practitioners to appreciate how these two methods contribute to a rigorous process of CBR programme evaluation.

Purpose: Determine the association of different social factors with Functional Capacity Evaluation (FCE) performance in adults.

 

Materials and methods: A systematic literature search was performed in MEDLINE, CINAHL, and PsycINFO electronic databases. Studies were eligible if they studied social factor’s association with the performance of adults undergoing FCE. Studies were assessed on methodological quality and quality of evidence. The review was performed using best-evidence synthesis methods.

 

Results: Thirteen studies were eligible and 11 social factors were studied. Considerable heterogeneity regarding measurements, populations, and methods existed among the studies. High quality of evidence was found for the association of FCE performance with the country of FCE and examiner’s fear behavior; moderate quality of evidence with previous job salary; and low or very low quality of evidence with compensation status, litigation status, type of instruction, time of day (workday), primary or mother language, and ethnicity. Other social factors were not studied.

 

Conclusions: Evidence for associations of various social factors with FCE performance was found, but robust conclusions about the strength of the associations cannot be made. Quality of evidence ranged from high to very low. Further research on social factors, also within a biopsychosocial context, is necessary to provide a better understanding of FCE performance.

Purpose: This study described how the Dutch and Canadian governments promote high performance sports, recreational sports, and physical activity (PA) among adults with disabilities on a national level.

 

Methods: An internet-based study was conducted to identify and select relevant documents and websites containing information about the national approach to promote disability sports and physical activities in the Netherlands and Canada.

 

Results: Both governments promote high performance sports in similar ways, but use different strategies to promote recreational sports and physical activities. The Dutch approach is characterized by using time-limited programs focusing on enhancement of sports infrastructure and inter-sector collaboration in which municipalities have key roles. The Canadian government promotes recreational sports in disabled populations by supporting programs via bilateral agreements with provinces and territories. Furthermore, the level of integration of disability sports into mainstream sports differs between countries.

 

Conclusions: The findings of this study may inspire policy makers from different countries to learn from one another’s policies in order to optimize national approaches to promote disability sports and PA on all levels.

Access to health care in an age of austerity: disabled people’s unmet needs in Greece

ROTAROU, Elena S
SAKELLARIOU, Dikaios

Since late 2009, Greece has been dealing with the effects of a debt crisis. The neoliberal principles embedded in the three structural adjustment programmes that the country accepted have required radical cuts in health care funding, which in turn have led to widening inequalities in health. This article focuses on access to health care for people with disabilities in Greece in the context of these structural adjustments. We investigate possible differences in unmet health care needs between people with and without disabilities, using de-identified cross-sectional data from the European Health Interview Survey. The sample included 5400 community- dwelling men and women aged 15 years and over. The results of the logistic regressions showed that people with disabilities report higher unmet health care needs, with cost, transportation, and long waiting lists being significant barriers; experience of all barriers was positively associated with low socio- economic status. These findings suggest that a section of the population who may have higher health care needs face greater barriers in accessing services. Austerity policies impact on access to health care in both direct and indirect ways, producing long-term disadvantage for disabled people. Social policies and comprehensive anti-discrimination legislation might help to address some of the barriers this population faces.

Background: There is need for ‘high-quality’ teachers who are equipped to meet the needs of all learners through provision of education for an inclusive society according to equal opportunities to all.


Objective: This paper investigates pockets of good practice in the adaptation of the curriculum for the inclusion of learners with special education needs (SEN) in selected primary schools in the Fort Beaufort District.


Method: The study adopted a qualitative research approach and employed a case study design. Eight teachers and 10 principals from 10 selected primary schools, 4 education district officials and 1 provincial official were interviewed. Purposive sampling was used to select the participants. Data were collected using document analysis and semi-structured interviews and were analysed thematically.


Result: The study established that teachers use methods relating to different teaching strategies, individual work, group work and extra work.


Conclusion: It was concluded that there are pockets of good practice of inclusion policy such as the use of different teaching strategies, individual work, group work and extra work for inclusion of learners with SEN in some of the selected primary schools in the poor rural context. The paper recommends adequate training for teachers in curriculum adaptation in order for all teachers to accommodate learners with SEN.

Background: The purpose of this study was to explore the psychological well-being of adolescents with physical disabilities living in inclusive community settings of Makonde Urban in Zimbabwe. An inclusive community is one that aims to remove exclusionary practices within the community and promote community systems that accept all people irrespective of their difference. Inclusive communities on their own are not uniquely designed for people with disabilities, but most developing countries have adopted them as a basic strategy to influence and enhance psychological well-being of people with disabilities.


Methods: A constructivist lived experience perspective underpinned this research, in which multiple case studies were used to interact with the participants on inclusion and psychological well-being of adolescents with physical disabilities. Purposive sampling was used to select 14 participants (9 males and 5 females). Data were collected through face-to-face interviews and transcribed verbatim. Four themes emerged from the thematic analysis of data sources.


Results: It was found that participants who were adolescents with physical disabilities living in inclusive community settings of Makonde Urban in Zimbabwe were having high levels of autonomy and choice, purpose in life, positive relations with others and good personal growth and self-acceptance.


Conclusion: The findings of this study should enable inclusive communities’ policy-makers and researchers to better understand the psychological well-being of adolescents with physical disabilities living in inclusive communities.

Background: The World Health Organisation recommends that services accompany wheelchair distribution. This study examined the relationship of wheelchair service provision in Kenya and the Philippines and wheelchair-use–related outcomes.


Method: We surveyed 852 adult basic manual wheelchair users. Participants who had received services and those who had not were sought in equal numbers from wheelchair-distribution entities. Outcomes assessed were daily wheelchair use, falls, unassisted outdoor use and performance of activities of daily living (ADL). Descriptive, bivariate and multivariable regression model results are presented.


Results: Conditions that led to the need for a basic wheelchair were mainly spinal cord injury, polio/post-polio, and congenital conditions. Most Kenyans reported high daily wheelchair use (60%) and ADL performance (80%), while these practices were less frequent in the Philippine sample (42% and 74%, respectively). Having the wheelchair fit assessed while the user propelled the wheelchair was associated with greater odds of high ADL performance in Kenya (odds ratio [OR] 2.8, 95% confidence interval [CI] 1.6, 5.1) and the Philippines (OR 2.8, 95% CI 1.8, 4.5). Wheelchair-related training was associated with high ADL performance in Kenya (OR 3.2, 95% CI 1.3, 8.4). In the Philippines, training was associated with greater odds of high versus no daily wheelchair use but also odds of serious versus no falls (OR 2.5, 95% CI 1.4, 4.5).


Conclusion: Select services that were associated with some better wheelchair use outcomes and should be emphasised in service delivery. Service providers should be aware that increased mobility may lead to serious falls.
 

People with disabilities and income-related social protection measures in South Africa: Where is the gap?

HANASS-HANCOCK, Jill
MCKENZIE, Tamlyn C.
2017

Expand view

Background: People with disabilities are at increased risk of poverty, particularly in low-and middle-income countries. However, recent evidence suggests that this association is more nuanced than previously anticipated and that we need better data to understand the opportunity and out-of-pocket costs that diverse groups of people with disabilities may experience.


Objective: This paper discusses if disability is associated with opportunity cost and loss of income both on the individual and household level in South Africa, and if these costs differ depending on disability type and severity.


Methods: For this purpose, the paper analyses General Household Survey 2011 data (people between 15 and 59) using descriptive statistics disaggregated via disability type and severity. The paper also assesses if social grants counteract these costs and reduce economic vulnerability.


Results: The analysis of the data reveals that people with disabilities are affected by issues relating to multidimensional poverty such as lower educational attainment and fewer employment opportunities. In addition, households of people with disabilities (with the exception of milder visual problems) earn significantly less than households without people with disabilities, and this particularly applies to households with people with severe disabilities. This vulnerability also varies by disability type. The country’s social protection mechanisms, in terms of social grants, counteract economic vulnerability to some extent but do not consider the nuanced economic impact of diverse conditions nor the increased out-of-pocket costs related to disability.


Conclusions: This calls for more equitable social protection mechanisms that include accessible services, livelihood programmes and disability benefits.

Background: Premature failures of wheelchairs in less-resourced environments (LREs) may be because of shortcomings in product regulation and quality standards. The standards published by the International Organization for Standardization (ISO) specify wheelchair tests for durability, safety and performance, but their applicability to products used in the rugged conditions of LREs is unclear. Because of this, wheelchair-related guidelines published by the World Health Organization recommended developing more rigorous durability tests for wheelchairs.


Objectives: This study was performed to identify the additional tests needed for LREs.


Methods: First, a literature review of the development of ISO test standards, wheelchair standards testing studies and wheelchair evaluations in LREs was performed. Second, expert advice from members of the Standards Working Group of the International Society of Wheelchair Professionals (ISWP) was compiled and reviewed.


Results: A total of 35 articles were included in the literature review. Participation from LREs was not observed in the ISO standards development. As per wheelchair testing study evidence, wheelchair models delivered in LREs did not meet the minimum standards requirement. Multiple part failures and repairs were observed with reviewed field evaluation studies. ISWP experts noted that several testing factors responsible for premature failures with wheelchair parts are not included in the standards and accordingly provided advice for additional test development.


Conclusion: The study findings indicate the need to develop a wide range of tests, with specific tests for measuring corrosion resistance of the entire wheelchair, rolling resistance of castors and rear wheels, and durability of whole wheelchair and castor assemblies.

Test–retest reliability and construct validity of the Aspects of Wheelchair Mobility Test as a measure of the mobility of wheelchair users

RISPIN, Karen L.
HUFF, Kara
WEE, Joy
2017

Expand view

Background: The Aspects of Wheelchair Mobility Test (AWMT) was developed for use in a repeated measures format to provide comparative effectiveness data on mobility facilitated by different wheelchair types. It has been used in preliminary studies to compare the mobility of wheelchairs designed for low-resource areas and is intended to be simple and flexible enough so as to be used in low-technology settings. However, to reliably compare the impact of different types of wheelchairs on the mobility of users, a measure must first be a reliable and valid measure of mobility.


Methods: This study investigated the test–retest reliability and concurrent validity for the AWMT 2.0 as a measure of mobility. For reliability testing, participants in a low-resource setting completed the tests twice in their own wheelchairs at least one week apart. For concurrent validity, participants also completed the Wheelchair Skills Test Questionnaire (WST-Q), a related but not identical validated assessment tool.


Results: Concurrent validity was indicated by a significant positive correlation with an r value of 0.7 between the WST-Q capacity score and the AWMT 2.0 score. Test–retest reliability was confirmed by an intraclass correlation coefficient greater than 0.7 between the two trials.


Conclusion: Results support the preliminary reliability and validity of the AWMT 2.0, supporting its effectiveness in comparing the mobility provided by different wheelchair types. This information can be used to enable effective use of limited funds for wheelchair selection at individual and organisational scales.

Discriminatory validity of the Aspects of Wheelchair Mobility Test as demonstrated by a comparison of four wheelchair types designed for use in low-resource areas

RISPIN, Karen L.
HAMM, Elisa
WEE, Joy
2017

Expand view

Background: Comparative effectiveness research on wheelchairs available in low-resource areas is needed to enable effective use of limited funds. Mobility on commonly encountered rolling environments is a key aspect of function. High variation in capacity among wheelchair users can mask changes in mobility because of wheelchair design. A repeated measures protocol in which the participants use one type of wheelchair and then another minimises the impact of individual variation.


Objectives: The Aspects of Wheelchair Mobility Test (AWMT) was designed to be used in repeated measures studies in low-resource areas. It measures the impact of different wheelchair types on physical performance in commonly encountered rolling environments and provides an opportunity for qualitative and quantitative participant response. This study sought to confirm the ability of the AWMT to discern differences in mobility because of wheelchair design.


Method: Participants were wheelchair users at a boarding school for students with disabilities in a low-resource area. Each participant completed timed tests on measured tracks on rough and smooth surfaces, in tight spaces and over curbs. Four types of wheelchairs designed for use in low-resource areas were included.


Results: The protocol demonstrated the ability to discriminate changes in mobility of individuals because of wheelchair type.
Conclusion: Comparative effectiveness studies with this protocol can enable beneficial change. This is illustrated by design alterations by wheelchair manufacturers in response to results.
