| Abstract | Objectives: The aim of this study was to investigate the psychometric properties of Rusbult’s relationship investment scale based on the main components’ analysis, through varimax rotation, and obtaining a precise instrument for Iranian samples. Methods: The statistical population of this study consisted of all 1416 married students of Qazvin Payame Noor University in the academic year of 1396 to 1397, from which 302 subjects were selected by convenience sampling. The statistical population consisted of 300 Payame Noor University students in Qazvin, who were selected by convenience sampling. Overall 176 of the cases were female and the rest were male. Results: The results obtained from the main components’ analysis using varimax rotation based on four factors converged with the English version of relationship investment scale and only some subscales needed to be modified as follows: Satisfaction (including questions 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 21, 22, 23, 24, and 25), alternative relationships (including questions 26, 27, 28, 29, 30, 31, 32, 35, 36, and 37), investment (including questions 16, 17, 18, 19, 20, 33, and 34), and commitment (including questions 11, 12, 13, 14, and 15). Conclusions: The results of this study revealed that Rusbult’s relationship investment scale is a suitable instrument to assess the quality of relationship between couples in Iran’s society and since one of the effective variables in sustaining marital life is couples’ investment in this relationship, Rusbult’s relationship investment scale is an appropriate instrument to achieve this goal. | en |
