Note 1: SD: standard deviation, ADL: activities of daily living, SE: self-efficacy for dietary restrictions, CE: control expectancy for dietary restrictions, SS: social support for dietary restrictions, and DRs: dietary restrictions.
Note 2: means and correlations were calculated using the full-information maximum likelihood method.
Note 3: means and standard deviations represent values before the variables were standardized.
Note 4: objective dietary restrictions represent a dependent and categorical variable; we did not calculate its correlations with the independent variables.
Note 5: < .05, < .01, and < .001.
