“…The BRIEF consists of eight scales (inhibit, shift, emotional control, initiate, working memory, plan/organize, organization of materials, monitor), which comprise two broad indices: Behavioral Regulation , profiling the ability to shift and modulate emotions and behavior via appropriate inhibitory control; and Metacognition , referring to the ability to cognitively self‐manage tasks and monitor performance. Among children, adolescents, and adults with ASD without intellectual disability, metacognitive EF is consistently highlighted as most closely related to children's communication, daily living, and social skills [Gilotty, Kenworthy, Sirian, Black, & Wagner, ; McLean, Harrison, Zimak, Joseph, & Morrow, , Peterson, Noggle, Thompson, & Davis, ; Pugliese et al, ; Wallace et al, ], though Pugliese et al [] also found that behavior regulation significantly predicted socialization skills. Fewer studies have investigated the contribution of BRIEF scales comprising the summative indices.…”
