|---|---|---|---|---|
| Primary | Verbal Working Memory | One week before the intervention | Verbal working memory will be assessed using the backward digit spans subtest from the third edition of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III). | ClinicalTrials.gov |

| Primary | Inhibition | One week before the intervention | The Stroop color and word test is a widely used assessment for measuring inhibition. In this test, participants will be presented with colour words printed in mismatched ink colors (for example, the word "red" written in blue ink). They will be instructed to quickly name the ink colour of each word while ignoring the word's meaning. This effort to suppress the meaning of the word to identify the ink colour consistently leads to longer response times compared to naming the colour of congruent stimuli (such as "red" printed in red ink). | ClinicalTrials.gov |

| Primary | Attentional Control and Cognitive Flexibility | One week before the intervention | The contingency naming test will assess attentional control and cognitive flexibility through four rules of increasing difficulty, using a stimulus set that includes nine practice items and 27 test items. Each stimulus will consist of an outer shape (circle, triangle, or square) in various colors (blue, yellow, or red), along with a smaller independent shape (circle, triangle, or square) inside the outer shape. Some stimuli will feature a backward arrow positioned directly above the outer shape. Participants will be instructed to name the stimuli based on the rule level within a set time limit. | ClinicalTrials.gov |

| Primary | School Satisfaction | One week before the intervention | School satisfaction will be assessed using six items derived from the Longitudinal Study of Australian Children. Respondents will rate each item on a four-point Likert scale ranging from strongly agree to strongly disagree. | ClinicalTrials.gov |

| Primary | Executive Function | One week before the intervention | A short form of the Behavior Rating Inventory of Executive Function (BRIEF) includes questionnaires for both parents and teachers aimed at evaluating EF in home and school settings. The BRIEF contains 24 items, which produce eight scales: Initiate, working memory, plan/organise, organisation of materials, monitor, inhibit, shift, and emotional control. Parents and teachers will rate their child or student's behaviour on a 3-point Likert scale, ranging from 1 (never) to 3 (often). | ClinicalTrials.gov |

| Primary | Social Participation | One week before the intervention | The Social Participation Questionnaire consists of 24 statements distributed across four subscales: Friendships/relationships (five items), contacts/interactions (nine items), student's social self-perception (five items), and acceptance by classmates (five items). Class teachers will complete the SPQ for the students by responding to the statements on a 5-point Likert-type scale, with options ranging from 1 (this does not apply at all) to 5 (this strongly applies). | ClinicalTrials.gov |

| Primary | Severity of Disability | One week before the intervention | The severity of disability will be measured based on the seven domains of life: material well-being, health, safety, productive activity, place in community, intimacy, and emotional well-being. The seven items will be rated on a 5-point Likert scale, ranging from 1 (not at all affected) to 5 (extremely affected). | ClinicalTrials.gov |
