Satisfaction with Love Life and Satisfaction with Life: Shortened Three-Item Versions Scales Among Brazilian College Students

Abstract

Satisfaction with Love Life Scale (SWLLS) and Satisfaction with Life Scale (SWLS) are cognitive measures of subjective well-being (SWB). This paper intended to scrutinize the psychometric characteristics and validity of the shortened 3-item forms of Satisfaction with Love Life Scale (SWLLS-3) and Satisfaction with Life Scale (SWLS-3) among Brazilian college students. The sample comprised 248 college students with an average age of 21.47 years. Confirmatory factor analysis (CFA) indicated that the two-dimensional model of the SWLLS-3 and the SWLS-3 presented good fit indices. The internal consistency of both measures was high. These scales demonstrated adequate convergent, and discriminant validity. As expected, the SWLLS-3 and the SWLS-3 scores correlated positively with constructs such as self-esteem and body appreciation, and negatively with loneliness. The associations between the shortened 3-item scales and well-being-related variables closely resembled those of the original 5-item versions. The shortened forms of the SWLLS and SWLS appear to be valid and reliable measurement instruments. In future research, it would be convenient to study psychometric properties in larger samples and other countries.
