Abstract

CASSEPP-BORGES, Vicente  and  PASQUALI, Luiz. The item reduction as an alternative to Triangular Love Scale. Psicologia [online]. 2014, vol.28, n.2, pp.11-20. ISSN 0874-2049.

The aim of this study was to assess the psychometric properties of Reduced Sternberg's Triangular Love scale (STLS-R). 1523 subjects of 13 Brazilian states responded the scale. The results indicated that the short version has good precision and items with high loads on a single factor. Confirmatory Factorial Analysis showed invariance of the factor structure of STLS-R for sex and region, but not for relationship type. The Item Response Theory suggests that the STLS-R is informative. Items are discriminatory, but relatively easy. The results suggest that the STLS-R is an excellent measurement instrument. However, it’s not recommended to leave the STLS full version.
