The Behavior Rating Inventory of Executive Function questionnaire is completed by parents / carers. It contains 80 statements of everyday problem behaviours related a range of executive function difficulties that are rated for frequency over the past six months. T-scores are derived for eight subscales: Inhibit, Shift, Emotional control, Initiate, Working memory, Planning, Organisation and Monitor. Three composite scores are also derived: Metacognition, Behaviour Regulation and Global Executive Function. All raw scores are converted to T-scores (M = 50, SD=10). Please note that the scoring instructions and the wording of each item are subject to copyright and are therefore not available in the data release.
