The present study is a reliability-generalization meta-analysis of 5 commonly used measures of romantic love: Rubin’s Loving and Liking scales, the Love Attitudes Scale, the Love Attitudes Scale–Short Form, the Passionate Love Scale, and the Triangular Love Scale. Data from 127 studies representing 38,132 participants provided internal consistency reliability estimates. The studies provide information on the average score reliability across studies and the effect of sample characteristics on score reliability across measures. The reliability of scores from several measures proved to be susceptible to the influence of sample characteristics, most notably, the ethnicity of the sample. The discussion provides recommendations to researchers and focuses on the ramifications of score reliability on love research.
