Abstract

Longitudinal studies of cognition are necessary to estimate individual developmental trajectories and to link these trajectories with neurodevelopment. Short task batteries, if psychometrically sound, may have benefits over lengthy assessments. This paper focuses on the assessment of cognition in the Adolescent Brain Cognitive Development™ (ABCD) Study. Previously, we performed a Bayesian Probabilistic Principal Components Analysis (BPPCA) on ABCD’s baseline data, extracting components representing general ability, executive function and learning/memory. Because ABCD’s cognitive assessments changed over time, a strategy is needed to evaluate the longitudinal stability of these component scores based on the modified batteries, changes in scores over time, and associations with external variables. The current analyses address these gaps using available data from the ABCD baseline, year 2 and year 4 assessments. We extracted components from the modified task batteries, aligning them with those described by Thompson et al. (2019) at baseline. When the battery is reduced from 9 to 7 variables (baseline to year 2) and from 7 to 5 variables (year 2 to year 4), a three-component structure remains a good fit with task loadings similar to those observed for the full baseline battery. There are strong intercorrelations among component scores across 5, 7, and 9 subtest solutions. Using components derived from the 5-subtest solution, age- and practice-related changes are longitudinally evident; longitudinal component scores also differentially associate with psychopathology indices and working-memory task-related MRI imaging activation. Researchers may wish to leverage this approach to assess how cognition relates to neurodevelopment and other sources of individual variation.

Code

No file of the authors' code could be read here: it is described below, and read at its source.

Tracing map

Proposed by the machine: these links were found in the paper and verified at the source, without human review. The map will receive a Zenodo DOI once one of the paper's authors has validated it with their ORCID.

What the map holds:

• 1 repository of the authors' code, each at its verified commit, with its license and how the link was found in the paper;
• 0 scripts, each with its path and the digest of its content;
• no match between paragraphs and code yet;
• neither the text of the paper nor the code itself.

Its JSON (tracing-map.json) is deposited on Zenodo with its DOI once the map is validated.
