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 {χ2= 256.7, df = 121, p = 0.07,
χ2/df = 2.12; TLI = 0.95; CFI = 0.93; RMSEA (90CI) = 0.075 (0.003, 0.077)} and w as superior w ithin dietary
behaviour (PBK: χ2/df = 2.12; p = 0.07 against TPB: χ2/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.
