摘要：BAT-7, TEA ABILITIES BATTERY: DESCRIPTION AND PSYCHOMETRIC PROPERTIESBAT-7 is a new psychometric tool for assessing three intellectual domains, general factor (g), fluid intelligence (Gf) and crystallized intelligence (Gc), and eight cognitive abilities: Verbal (V), Spatial (E), Attention (A) and Concentration (CON), Reasoning (R), Numerical (N), Mechanical (M) and Orthography (O). It consists of three forms of increasing difficulty (E, M and S) and it is focused on the assessment of school and college students, as well as adults with different educational background. The present study aims to provide a description of the BAT-7 development and the main features of it, and a summary of its psychometric properties, mainly its reliability and validity. BAT-7 was administered to a Spanish standardization sample of 4,263 students (age between 12 and 18) and 1,507 adults. Reliability was studied with ordinal alpha, Cronbach’s alpha and tests information functions. Validity was explored by multigroup CFA. 3P IRT model showed a statistical fit for all items. Ordinal alpha ranged from .79 to .91 for test scores and from .91 to .97 for composite scores. The model based on CHC theory showed a good fit to the observed data (RMSEA=.034; SRMR=.026; CFI=.981). The results, in terms of TRI model fitting, reliability and validity, suggest that the BAT-7 is a useful, flexible and highly reliable test for assessing the cognitive abilities, and provide evidences supporting the use of the battery for the assessment of intellectual abilities in children and adults. An estimate of general ability (g), fluid intelligence (Gf) and crystallized intelligence (Gc) also can be obtained by applying the BAT-7.
