Pre-intention Mediators within the Theory of Planned Behaviour Applied to Dietary Practices among Type II diabetics: What is the Position of Perceived Dietary Knowledge?
並列摘要
In this study we formulated and applied planned behaviour knowledge theory in predicting dietary behavior among Type 2 diabetics. The study was conducted for three months within the diabetic clinic at Kisii Hospital in Nyanza Province in Kenya and adopted sequential mixed methods design combing both qualitative and quantitative phases. The initial data collection process began with Focus Group Discussions and ended with structured questionnaire interviews among of 237 Type 2 diabetic patients. Qualitative data was analyzed using constant comparative approach in grounded theory analysis and specific used to develop structures questionnaire. Structural equation modeling using maximum likelihood was used to analyze quantitative data. The results based on the common fit indices revealed that the planned behaviour knowledge theory fits the data acceptably well among the Type 2 diabetes and within dietary behavior {x^2=256.7, df=121, p=0.07, x^2/df=2.12; TLI=0.95; CFI=0.93; RMSEA (90CI)=0.075 (0.003, 0.077)} and was superior w ithin dietary behaviour (PBK: x^2/df=2.12; p=0.07 against TPB: x^2/df=2.53, p=0.02) compared to the traditional theory of planned behaviour. This implies that perceived knowledge is an important preliminary locus of control when considering use of the theory of planned behaviour as a reference framework for promoting healthy dietary practice among Type 2 diabetics.
