Conclusion:
Overall, the present study provided support for the utility of an
intervention informed by an integrated theoretical model, incorporating
aspects of both the TPB and the HAPA, targeting a critical behaviour
(i.e., carbohydrate counting) for a clinical population of individuals
with T2D. These results were encouraging not only in improving
cognitions and showing promise, especially for constructs in the
volitional phase of decision making, but also self-reported behaviour
and a biochemical outcome. The intervention did not support a change in
low-fat food consumption nor physical activity. Further research is
needed to assess the more prolonged-term effects of interventions with a
focus on carbohydrate counting and to attain generalized adherence to
key management behaviours among this at-risk group to reduce the
negative health consequences for people with a T2D diagnosis.
