This study aimed to adapt the Tetrangular Love Scale (TLS) to the Brazilian context, gathering evidence of its factorial validity and reliability, in addition to factorial invariance with respect to participants' gender. The participants were 200 undergraduate students from João Pessoa (PB), with a mean age of 25 years old (104 women and 96 men), most of them single (76.9%). They answered demographic questions and filled the ETA, which consists of 20 items rated on a 5-points scale. Three different models were tested: uni- (all items loading on a single factor), tri- (in line with Sternberg's model), and tetrafactorial (Yela's model: commitment, intimacy, erotic passion, and romantic passion). This last model was more appropriate, and its corresponding four factors showed Cronbach's alphas above 0.70. Evidence was also gathered for the factorial invariance of this measure in groups of women and men. In conclusion, these findings support the psychometric adequacy of the ETA, indicating that it may be used in future studies to know the correlates of the love factors.
