Using the Mobile Toolbox in child and adolescent samples: A feasibility study.

Cognitive research with developmental samples requires improved methods that support large‐scale, diverse, and open science. This paper offers initial evidence to support the Mobile Toolbox (MTB), a self‐administered remote smartphone‐based cognitive battery, in youth populations, from a pilot sample of 99 children (Mage = 11.79 years; 36% female; 53% White, 33% Black or African American, 9% Asian, and 15% Hispanic). Completion rates (95%–99%), practice performance (96%–100%), internal consistency (0.60–0.98), and correlations with similar NIHTB measures (0.55–0.77) provide the first evidence to support the MTB in a youth sample, although there were some inconsistencies across measures. Preliminary findings provide promising evidence of the MTB in developmental populations, and further studies are encouraged. [ABSTRACT FROM AUTHOR]
