Introduction:

Children and adolescents are a difficult-to-image population due their tendency to move during scanning sessions. Prior work demonstrates that neutral and positive movie stimuli reduce in-scanner movement for this population. Movies have also started to emerge as a disorder-relevant stimulus for probing threat- and anxiety-related neural dynamics. Yet, no study has examined how anxiety symptoms and movie-induced states of anxiety impact in-scanner motion among youth. One could imagine such anxiogenic media induce excessive movement, given the physiological responding it can elicit.

Methods:

We assessed: 1) the extent to which an anxiety-inducing movie clip altered in-scanner data quality (movement, censoring, and DVARS) in a pediatric sample with and without anxiety disorders (n=78); and 2) investigated interactions between anxiety symptoms and movie-attenuated motion in a highly powered, transdiagnostic pediatric sample (n=2058).

Results:

Our results suggest anxiogenic movie-watching in fact reduces in-scanner movement compared to resting-state (ps < .05), increasing the quantity/quality of data. In one measure, pathological anxiety appeared to impact movie-attenuated motion, but the effect was small.

Conclusions:

The present study demonstrated that anxiogenic movie-watching was associated with decreased in-scanner motion and increased signal quality compared to resting-state scanning. There was not sufficient evidence to suggest anxiety symptoms moderate this effect. Even if it does, the effect size of anxiety appears of a far lower magnitude compared to that of age and condition. In sum, our results encourage the use of movie-watching for studying induced- and pathological anxiety on methodological grounds, suggesting movie-watching may confer potential boosts to statistical power for developmental neuroimaging studies of anxiety via increases to data quality and quantity.

The Open Science Special Interest Group (OSSIG) is introducing a reproducibility challenge for OHBM 2025. This new initiative aims to enhance the reproducibility of scientific results and foster collaborations between labs. Teams will consist of a “source” party and a “reproducing” party, and will be evaluated on the success of their replication, the openness of the source work, and additional deliverables. Click here for more information. Propose your OHBM abstract(s) as source work for future OHBM meetings by selecting one of the following options:

I do not want to participate in the reproducibility challenge.
