Validation and reliability of The Childhood Executive Function Inventory (CHEXI) in Spanish primary school students

Given the enormous influence of executive functions in school and life success, it is necessary to identify EF levels and address them in a reliable way with tools accessible to practitioners. Two studies were conducted. In study 1, the psychometric properties of the Spanish version Children’s Executive Functioning Inventory (CHEXI) in a representative sample of 1230 primary school students from 9 to 12 years old was investigated. According to Barkley’s hybrid model, CHEXI showed good fit indices on the two subscales: working memory and inhibition (Χ² =949.32, p < 0.001, CFI = 0.98, TLI = 0.98, SRMR = 0.06, RMSEA = 0.05), as well as excellent internal consistency (ω ≥ 0.84–0.91; α ≥ 0.84–0.91). In study 2, the efficacy of the CHEXI for the observation of EF deficits related to ADHD symptoms in children was analysed. Significant differences in parent-reported scores were observed between typically developing students and students diagnosed with ADHD (p = < 0.001, η2partial = 0.09 – 0.10). The results showed that the CHEXI is a reliable instrument for measuring EF in Spanish children, and, it could be a useful tool for the identification of ADHD in these ages
