Mixed-methods research: A tutorial for speech-language therapists and audiologists in South Africa

Background: Mixed-methods research (MMR) offers much to healthcare professions on clinical and research levels. Speech-language therapists and audiologists work in both educational and health settings where they deal with real-world problems. Through the nature of their work, they are confronted with multifaceted questions arising from their efforts to provide evidence-based services to individuals of all ages with communication disorders. MMR methods research is eminently suited to addressing such questions. Objective: The aim of this tutorial is to increase awareness of the value of MMR, especially for readers less familiar with this research approach. Method: A literature review was conducted to provide an overview of the key issues in MMR. The tutorial discusses the various issues to be considered in the critical appraisal of MMR, followed by an explanation of the process of conducting MMR. A critical review describes the strengths and challenges in MMR. Results: MMR is less commonly used or published in the fields of speech-language therapy and audiology. Conclusion: Researchers working in teams can draw on the strengths of different disciples and their research approaches. Such collaborative enterprises will contribute to capacity building. Researchers, SLTs and audiologists are encouraged to make use of MMR to address the complex research issues in the multicultural, multifaceted South African context. MMR makes an important contribution to the understanding of individuals with communication disorders, and in turn, researchers in the two disciplinary fields of speech-language therapy and audiology can contribute to the development of this research approach. MMR is well suited to the complexity of South African contexts and its populations, as it can provide multiple perspectives of a topic.

Communication characteristics of young children with HIV in South Africa as reported by some physicians

HIV has been shown to have significant effects on the development of a child. Currently, there is limited South African research regarding HIV and specific characteristics of communication development, and the treatment thereof, in the child infected with HIV. The objective of the research was to describe the communication characteristics of a group of children between the ages of 0 and 5 years infected with HIV at a hospital in Gauteng, South Africa. Clinic records of 203 children infected with HIV between the ages of 0 and 5 years were reviewed using a pre-designed checklist within the outreach clinic of a large regional hospital. A questionnaire was completed by four medical practitioners working with this population within the outreach clinic. A total of 91.62% of the infected children were diagnosed as being either in Stage III or IV of the disease (according to the WHO classification system of 2005), with all infants presenting with a CD4 count of ≤60. Most (75.37% of the total sample) were receiving Highly Active Antiretroviral Therapy (HAART) at the time the data were collected. According to their medical, social, communication and general development, almost all the children qualified for Early Communication Intervention (ECI) but were not recorded as being referred for such services. A large proportion of the target population presented with opportunistic infections and/or HIV associated conditions. The results highlight the developmental characteristics of children living with HIV, and identify the need for medical doctors and allied health professionals to be provided with relevant literature or training regarding the communication development of children infected with HIV. This will facilitate appropriate referrals for ECI services.
