Abstract

General life satisfaction is often measured by a single item, but psychometric characteristics of this form of measurement are rarely verified. The main goal of this research is the verification of reliability and validity of single-item life satisfaction measurement by comparing single-item measurement with the Satisfaction with Life Scale (SWLS). The research was conducted on three independent convenience samples of students and adults. The reliability of single-item life satisfaction measurement was evaluated using two evaluation methods (using the correction for attenuation formula and factor analysis). Both methods indicate satisfactory reliability of a single item in all three independent samples. Single-item life satisfaction measurement showed appropriate criterion validity. In order to verify construct validity, the correlation between two life satisfaction measurements and general psychological distress measurements (CORE-10, CORE-OM, and DASS-21) was utilized. The results indicate satisfactory construct validity of single-item life satisfaction measurement, which implies that this measurement is more strongly associated with measurements of general psychological distress.
