Academic Diligence Task

The Academic Diligence Task (ADT) was designed to mirror a real-world choice students must confront when completing homework: the choice to remain engaged in tedious, but important assignments, and/or browse the Internet to play video games. Specifically, the task consists of a split-screen interface with the choice to complete single-digit subtraction problems (“Do Work”) or play games (“Play games”).

A sample version of the task can be found here:


If you’d like to use the task in your own study, please contact us.

The task runs using HTML5. The files need to be saved on a web server that you control.  The task is compatible with most browsers, as well as most smartphones and tablets.

The ADT is free for research purposes, with the stipulation that Galla et al. (2014) is cited:

Short-Form Five Facet Mindfulness Questionnaire (FFMQ) for Adolescents

Our lab validated a 15-item short-form FFMQ for high school-age youth.

The questionnaire is freely available for research purposes in Abujaradeh et al. (2020):

Appearance-Related Social Media Consciousness Scale

Our lab participated in a validation study of a short scale for adolescent youth designed to measure the extent to which individuals’ thoughts and behaviors reflect ongoing awareness of whether they might look attractive to a social media audience.

The questionnaire is freely available for research purposes in Choukas-Bradley et al. (2020):
