Objective: This study describes the development and validation of the Sorokin Psychosocial Love Inventory (SPSLI) measuring love actions toward a former spouse. Method: Classical measurement theory and confirmatory factor analysis (CFA) were utilized with an a priori theory and factor model to validate the SPSLI. Results: A 15-item scale containing five subscales (intensity, extensity, purity, adequacy, and duration) showed good fit, statistically significant factor loadings, good reliability, and validity. Multigroup CFA indicated both measurement equivalence and structural equivalence between males and females. Discussion: The SPSLI supports Sorokin's multidimensional theory of love and provides clinicians a method to measure love actions of divorcing individuals. Implications for practice and future research are discussed. (Contains 1 figure and 8 tables.)
