Outcome Measures

Primary Outcomes (3)

  • Food Choice Change

    Children rated on a 4-point Likert scale (1-Strong No, 2-No, 3-Yes, 4-Strong Yes) about whether they would choose to eat 60 different foods (30 unhealthy, 30 healthy) on a computer program. Higher values for unhealthy foods represented unhealthier food choices and higher values for healthy foods represented healthier food choices. The mean scores for unhealthy food choices were compared between pre- and post-intervention, and the mean scores for healthy food choices were compared between pre- and post-intervention.

    Pre (day 0) and post intervention (day 7-10).

  • Food Tastiness Change

    Children rated on a 4 point Likert scale (1-Very Bad, 2-Bad, 3-Good, 4-Very Good) about how tasty 60 different foods (30 unhealthy, 30 healthy) were on a computer program. A regression coefficient (beta) of food taste was estimated at an individual level by fitting a linear regression model where taste and health ratings predicted food choices for each child. Higher estimated regression coefficients represented higher decision weights of food taste attributes in food choices. The mean estimated regression coefficients were compared between pre- and post-intervention.

    Pre (day 0) and post intervention (day 7-10).

  • Food Health Change

    Children rated on a 4 point Likert scale (1-Very Unhealthy, 2-Unhealthy, 3-Healthy, 4-Very Healthy) about how healthy 60 different foods (30 unhealthy, 30 healthy) were on a computer program. A regression coefficient (beta) of food healthiness was estimated at an individual level by fitting a linear regression model where taste and health ratings predicted food choices for each child. Higher estimated regression coefficients represented higher decision weights of food healthiness attributes in food choices. The mean estimated regression coefficients were compared between pre- and post-intervention.

    Pre (day 0) and post intervention (day 7-10).

Secondary Outcomes (1)

  • Level of Self-Control, as Measured by the Self-Control Scale

    Children completed this item at the baseline visit (pre intervention).

Study Arms (2)

Control

PLACEBO COMPARATOR

Children were exposed to food commercials without narratives.

Behavioral: Control

Intervention

EXPERIMENTAL

Children were exposed to narrative statements that were shown and read aloud in between commercials played.

Behavioral: Commercial Advertising Literacy Training

Interventions

Children were shown food commercials and in between those commercials they saw and heard statements such as "These foods won't make you happy" and "Those foods are so unhealthy."

Intervention
ControlBEHAVIORAL

Children were shown food commercials that were the same length as the other group but did not receive any information about whether the content was truthful.
