Trial Outcomes & Findings for Trial on the Effect of Media Multi-tasking on Attention to Food Cues and Cued Overeating (NCT NCT03882957)

Last Updated: 2022-06-14

Results Overview

Eye-tracking will be used to measure the amount of time spent looking at static food cues while participants play a media game on the computer. The amount time spent looking at a food cue is a measure how much attention was given to the food cue. The longer the looking time, the greater amount of attention.

PRIMARY outcome

Timeframe: approximately 15 minutes post-intervention

Population: Cumulative fixation duration. Five children were excluded from the computation of these eye tracking metric because of unsuccessful eye tracking calibration.

PRIMARY outcome

Timeframe: approximately 10 minutes prior to the intervention

Participants reported on their usual media multitasking using the short form media multitasking index. This index asks about media multitasking with other print and digital media during four primary activities: 1) watching television or movies, 2) playing video games, 3) reading books or magazines (not assigned for school), and 4) doing homework. For each activity, participants reported the frequency with which they multitasked by engaging in the other activities by using a 5-point likert scale (i.e., 0=Never, 1=Rarely, 2=Sometimes, 3=Often, 4=Always). A usual media multitasking score was computed by taking the average of the Likert response. The score ranges from 0 to 4 with a higher score indicative of higher self-reported usual media multitasking.
