Abstract
The aim of the present study is to examine the internal structure of the Test Anxiety Inventory-Spanish version (TAI-S) and have a brief version. It was assessed of a sample of 376 Peruvian university students (73.1% women) between 16 and 55 years old (M = 20.71). The internal structure of TAI-S was analyzed by using structural equation modeling (factorial confirmatory analysis) and the short version was obtained on the basis of a Bifactoral model and conceptual approaches. Four models were evaluated: orthogonal, oblique, bifactor and one-dimensional. As the result, the TAI-S is constituted by a single dimension. Likewise, the short version shows robust indicators and based on the empirical evidence with the long version. Finally, the two versions showed reliability coefficient with high magnitudes. In conclusion, the two version studied show favorable psychometric properties that support its use in the Peruvian context.
Highlights
El Test Anxiety Inventory (TAI) posee una base teórica sólida (Spielberger, 1980a, 1980b; Spielberger & Vagg, 1995), y cuenta con múl ples estudios empíricos e instrumentales en población universitaria de diferentes contextos culturales
Algunos estudios instrumentales (Oktedalen & Hagtvet, 2011; Papantoniou et al, 2011; Ware & Galassi, 1990) no interpretan la elevada correlación interfactorial (φ = .800, φ = .906, φ = .883, respec vamente) como indicador de mul colinealidad (Arias, 2008) y fuente potencial de información redundante a causa de la presencia de un factor general más robusto e interpretable, en lugar de dos específicos
Finalmente, a fin de brindar más evidencias a favor de la unidimensionalidad del TAI-E, fue evaluado el ajuste de un modelo unifactorial (M4), obteniéndose índices de magnitudes aceptables: SB-χ2(152) = 354.192 (p < .001); CFI = .987; RMSEA (IC 90%) = .060 (.051, .068); SRMR =
