Theoretical background
The ADEXI is a rating scale that measures everyday executive functioning in adults. It measures two executive functions (working memory and inhibition) that are relevant to the regulation of behavior and the adaptative response to various environmental demands. The everyday executive functions rating scales (e.g., CHEXI, ADEXI, TEXI, and BRIEF) show a collinear relationship with measures of behavior exhibited by children, adolescents, and adults in different contexts. Studies demonstrated that ADEXI has adequate psychometric properties, it is useful for the understanding of adults' executive functioning, and it has adequate diagnostic accuracy in Attention Deficit/Hyperactivity Disorder (ADHD).
Description
Assessment domain: Executive functions. Psychological assessment.
Type of instrument: Self-report and informant-report.
Number of items: 14 items, Likert scale with a 5-point scale (ranging from “Definitely not true” to “Definitely true”).
Administration: Individual or group, 5 minutes.
Population: Adults (self-report and informant forms).
Dimensions
The ADEXI consists of 14 items organized into two factors: Working Memory (9 items) and Inhibition (5 items).
Studies
The ADEXI is translated and/or validated in several countries (e.g., China, Spain, Hungary, England, Iran, Poland, Portugal, and Sweden). The results obtained with healthy adults and clinical samples (e.g., ADHD) confirm the robustness of its psychometric properties. Studies with adults with ADHD demonstrate the usefulness of the ADEXI in identifying executive function deficits and their accuracy in discriminating ADHD.
Future Research
Future studies with ADEXI will include factorial, convergent, and discriminant validity analysis. The Portuguese version of ADEXI can be used in clinical evaluations and for research.
