Computer-aided learning in disadvantaged communities in the Southern Cape and Karoo - A nutrition education initiative

Abstract

Objective: To evaluate the efficacy of a computer-aided learning (CAL) nutrition module. Design: A pre-test/post-test (immediate and follow-up posttesting) design was used to evaluate the impact of the CAL nutrition module, using validated multiple-choice questionnaires. The module consisted of five interactive submodules each covering a single concept of nutrition (5 - 10 minutes in duration). Setting and subjects: The total sample included 141 lowincome Afrikaans-speaking clients with low literacy levels attending clinics involved in the literacy programme in the Southern Cape and Karoo. Outcome measures: To evaluate the impact of the CAL nutrition module regarding knowledge, attitude and behaviour using differences between pre- and post-test scores. A one-tailed z-test for comparison of knowledge and attitude scores and a χ2-test for responses to behaviour questionnaires were used for statistical analysis. Results: The improvement in acquired and retained mean knowledge and attitude scores was highly significant (P = 0.002). Behaviour improved significantly and was retained for at least a month regarding more meals (P = 0.005), milk intake (P = 0.005) and legume intake (P = 0.01). Conclusions: The use of the interactive CAL nutrition module resulted in knowledge being acquired and retained and positive changes in attitude and behaviour. This has led to it being translated into English and Xhosa as well as additional modules being added.
