Psychometric Properties of the Spanish Version of the Self-Report Teenage Executive Functioning Inventory (TEXI)

The purpose of the present study was to validate the Spanish version of the Teen Executive Functioning Inventory (TEXI) and to investigate its psychometric properties. The TEXI was translated and back-translated into Spanish, and administered by high schools to adolescents aged 14-18 years (N = 902). The findings presented a bifactor structure (inhibition, working memory, and the general factor of Executive Functioning) with adequate fit indexes (Comparative Fit Index = 0.94, Root Mean Square Error of Approximation = 0.07, Standardized Residual Mean Squared Ratio = 0.03), which confirmed the original structure of the test. Also, it showed good reliability for the general factor and its subscales (α/ω > 0.90). The invariance analysis indicated differences for the interpretation of the instrument based on gender. Specifically, girls significantly pointed out a worse scoring in most of the items of the TEXI (p < .05). In conclusion, the Spanish version of the TEXI is a short, valid, reliable, and easy-to-fulfill screening for measuring working memory, inhibition, and executive functions in Spanish adolescents.
