Four-dimensional hierarchical structure of love constructs in a cross-cultural perspective

Abstract

This article reports new methodology for cross-cultural exploration of psychometric properties of a four-dimensional hierarchical love scale. We collected data from 2831 participants from nine regional locations from six countries and assessed their responses to the love scale as well as several other love feelings. We applied a new methodological approach using recently advanced statistical methods to the comparison of forty love attitudes underscoring four distinct latent attitudes associated with love to another person in romantic relationships across these samples. The results demonstrate the importance of measurement invariance tests for cross-cultural comparison of scores on love scales. To properly assess measurement invariance, we suggest five statistical procedures, which we investigated in this study: (1) making corrections for acquiescence and extreme response biases; (2) taking into consideration cultural uniqueness in how participants respond to the measures, which may contribute to poor model fit; (3) accounting for such cultural uniqueness to make cross-cultural comparisons more valid; (4) removing items, which substantially contribute to poor model fit; and (5) shortening the subscales when scoring and analyzing the data. The results of the studies propose two shortened versions (33 and 30 items) of the love scale as two cross-culturally valid and invariant alternatives to the original 40-item scale.
