The purpose of this research was to thoroughly study the psychometric properties of the Love Bank Inventory (LBI) with married participants. The LBI is a 21-item Likert-type English survey developed to measure romantic love for a partner. Two studies were conducted with independent data sets (Study 1: n = 143; Study 2: n = 142) that represented 22- to 62-year-old heterosexual, nondyadic married respondents with multicultural citizenship. The results of the two studies provide support for (a) a single-factor model, (b) convergent validity with a positive correlation with the statement about romantic love (rs = .67 - .68) and construct criterion validity with a positive correlation with the Locke-Wallace Marital Adjustment Test (r = .76 - .80), (c) internal consistency of LBI statements (? = .95 - .96,), and (d) test-retest reliability (r = .88). These two studies provide support for the use of the LBI as a free tool to assess romantic love in marriage education development and applied settings.
