Trial Outcomes & Findings for Promoting Resilience to Food Commercials Decreases Susceptibility to Unhealthy Food Decision-Making (NCT NCT04905498)
NCT ID: NCT04905498
Last Updated: 2023-03-30
Results Overview
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.

Control
Children were exposed to food commercials without narratives.
Control: 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.
|
Intervention
Children were exposed to narrative statements that were shown and read aloud in between commercials played.
Commercial Advertising Literacy Training: 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."

PRIMARY outcome
Timeframe: Pre (day 0) and post intervention (day 7-10).Population: The experimenter assigned children to one of two groups using a random assignment of drawing cell numbers pre-assigned for each group.
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.

PRIMARY outcome
Timeframe: Pre (day 0) and post intervention (day 7-10).Population: The experimenter assigned children to one of two groups using a random assignment of drawing cell numbers pre-assigned for each group.
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.

SECONDARY outcome
Timeframe: Children completed this item at the baseline visit (pre intervention).Population: The experimenter assigned children to one of two groups using a random assignment of drawing cell numbers pre-assigned for each group.
Children completed the 36-item self-control scale. Each item is rated on a 5-point Likert scale from 1 (not at all like me) to 5 (very much like me). A total score (i.e., 36 response scores were summed) was computed for each child. The total score ranged between 36 (minimum) and 180 (maximum). The higher total score represented higher (better) perceived self-control. No subscales were used.
