Trial Outcomes & Findings for Mobile Attention Retraining in Overweight Female Adolescents (NCT NCT02977403)

NCT ID: NCT02977403

Last Updated: 2025-05-31

Results Overview

AB was obtained for each stimulus pairing (High-Palatability Food \[HPF\] minus Non-Food \[NF\] image, Low-Palatability Food \[LPF\] minus NF image, HPF minus LPF image). Trials where the probe appeared behind the more food-salient cue (e.g., a HPF image, or LPF vs NF image) were considered congruent trials. Trials where the probe appeared behind the less salient cue (e.g., NF image, or LPF image when the other image was a HPF image) were considered incongruent trials. The average reaction time during incongruent trials was subtracted from reaction time during during congruent trials. Positive scores represent a quicker reaction time for (and bias towards) the more palatable stimulus, and negative scores represent a slower reaction time for (and bias away from) the more palatable stimulus. A difference score of 0 represents no bias towards or away from the more palatable stimulus. Only trials with correct responses for the direction of the probe were included in computations.

PRIMARY outcome

Timeframe: 2-weeks

Population: Computer failures led to missing data for many participants. There were interruptions in data recording during magnetoencephalography sessions that were not predictable due to equipment failures.

AB was obtained for each stimulus pairing (High-Palatability Food \[HPF\] minus Non-Food \[NF\] image, Low-Palatability Food \[LPF\] minus NF image, HPF minus LPF image). Trials where the probe appeared behind the more food-salient cue (e.g., a HPF image, or LPF vs NF image) were considered congruent trials. Trials where the probe appeared behind the less salient cue (e.g., NF image, or LPF image when the other image was a HPF image) were considered incongruent trials. The average reaction time during incongruent trials was subtracted from reaction time during during congruent trials. Positive scores represent a quicker reaction time for (and bias towards) the more palatable stimulus, and negative scores represent a slower reaction time for (and bias away from) the more palatable stimulus. A difference score of 0 represents no bias towards or away from the more palatable stimulus. Only trials with correct responses for the direction of the probe were included in computations.

Population: Equipment failure meant many participants did not have data for this analysis

Change in beta band (13-35 Hz) oscillatory power at the caudate left hemisphere during attention capture (0-250ms following stimulus). Oscillatory power was normalized as per NeuroImage 39 (2008) pp 1788-1802, by estimating noise power as ρθ = WθTΣWθ (where Wθ is a (M × 1) column vector of weighting parameters that are tuned specifically to the location and orientation represented by θ, Σ represents the noise covariance matrix and ρθ is the beamformer-projected sensor noise power at the location and orientation θ). Within each stimuli-pairing and attention phase, oscillatory power during the incongruent trials was divided by oscillatory power during the congruent trials, then log transformed. Given a ratio was used, the oscillator power outcomes are unitless. Change in power (post-intervention minus pre-intervention) was calculated. Positive changes represent an increase in oscillatory power from pre- to post intervention.
