Giggle gauge: a self-report instrument for evaluating children's engagement with technology

The Giggle Gauge offers a quick and simple way for researchers to evaluate the engagement of systems designed for children. This self-report metric is based on prior work delineating the components of engagement and was designed to address the limitations of children's cognitive development (e.g., by focusing on simple language and rapid administration). Through a process of iterative design (N = 23, ages 4 -- 10) and co-design (N = 8, ages 7 -- 11), we refined the items of this metric to ensure children's comprehension. A validation study with 26 children, ages 4 -- 7, confirmed the validity and reliability of the Giggle Gauge through the assessment of three properties: known-groups validity, criterion validity, and test-retest reliability. We simultaneously developed a bifurcated response type, intended to reduce the cognitive load of traditional ordinal response, and show through participant quotes that it may decrease the cognitive load of self-report questions for children.
