MULTIDIMENSIONAL EVALUATION OF THE GENERAL AND SPECIFIC FACTORS OF ADHD IN CHILDREN POPULATION WITH THE BIFACTOR-ESEM APPROACH
Nine ESEM and CFA first-order and bifactor models of attention deficit hyperactivity disorder (ADHD) were estimated using confirmatory factor analysis (ICM-CFA) and exploratory structural equation models (ESEM) to study its factorial structure according to the evaluations of the parents through the Inventory of Child and Adolescent Behavior: version for parents (CABI) on the behaviour of 632 children from 6 to 16 years old (M = 10.46, SD = 2.35) from the city of Talca (Chile). The bifactor ESEM model of three specific factors (deficit of attention, hyperactivity and impulsivity) showed the best fit and interpretability. There was a strict invariance between the sexes. In addition, the bifactor model provided a solution to the inconsistencies found earlier in the factorial models of ADHD. However, the low reliability of the specific factor’s casts doubts on the utility of the subscales for the measurement of ADHD.
