A summary of the article is shown below:

The adaptation of individually administered psychological tests from paper to app-based administration formats can present unique threats to the construct and raw-score equivalence of the paper and digital formats. We discuss these potential threats and describe a study evaluating the equivalence of paper and digital versions of the Wechsler Intelligence Scale for Children, fifth edition (WISC-V), which has been adapted to an app-based testing platform called Q-interactive. The present study (N = 350) used an equivalent-groups design to assess the raw-score equivalence of 18 WISC-V subtests that were designed with the intent of minimizing format effect. Effect sizes in standard deviation units were small, ranging from -0.20 to 0.20 (mean absolute value = 0.09), and format effects were unrelated to ability level, age, sex, or parent education. These results suggest that when tests are designed or adapted with digital-paper equivalence as a goal, digital-paper raw-score equivalence can be achieved across a variety of construct domains.
