Abstract
We sought to elucidate the causal effect of patients’ self-appraisal of their dietary regimen on their control beliefs among adults with type 2 diabetes. Data from 176 outpatients were assessed using a two-wave cross-lagged panel model. We found that a cross-lagged path connecting dietary appraisal at baseline to perceived control at one year (β = .30, p = .003) was larger than a path connecting perceived control at baseline to dietary appraisal at one year (β = —.16, p = .07). We conclude that dietary appraisal has a feedback effect on the future perceived control of type 2 diabetes.
