  1. The impact of computer-tailored feedback and iterative feedback on fat, fruit, and vegetable intake.

    Article - En anglais

    A randomized trial was conducted to study the impact of individualized computer-generated nutrition information and additional effects of iterative feedback on changes in intake of fat, fruits, and vegetables.

    Respondents in the experimental group received computer-generated feedback letters tailored to their dietary intake, intentions, attitudes, self-efficacy expectations, and self-rated behavior.

    After the first feedback letter, half of the experimental group received additional iterative feedback tailored to changes in behavior and intentions.

    The control group received a single general nutrition information letter in a format similar to the tailored letters.

    Computer-tailored feedback had a significantly greater impact on fat reduction and fruit and vegetable intake than did general information.

    Iterative computer-tailored feedback had an additional impact on fat intake.

    The results confirm that computer-generated individualized feedback can be effective in inducing recommended dietary changes and that iterative feedback can increase the longer term impact of computer-tailored nutrition education on fat reduction.
