In this psychometric research, the validity and reliability of the 45-item Sternberg Triangular Love Scale (STLS) was analyzed in a sample of 296 people from the city of Arequipa (located in southern Peru). 56.1% were women and 43.9% were men with an average age of 40.7 years. The STLS has three components: Intimacy, Commitment and Passion. For statistical processing, confirmatory factor analysis was applied to analyze the internal structure and the ordinal alpha test to estimate reliability. It was found that the STLS has a three-factor structure, after eliminating 11 items because they loaded on two or more factors. The scale was reduced to 34 items, with adequate goodness-of-fit indexes and reliability with indexes greater than .93 in each of its three factors.

Keywords : Love; Intimacy; Passion; Commitment; Sternberg; Validity; Reliability.
