In this study, we developed Japanese versions of the measuring optimism in romantic relationships and the measuring perceptions of efficacy or control in romantic relationships (the relational optimism scale, the relational efficacy scale, respectively; Murray & Holmes, 1997). Also, we confirmed their factor structures, and further examined their reliabilities and validities. Participants were 332 undergraduates (167males, 165females). The results of factor analysis showed that the relational optimism scale was composed of 2 factors; “union expectancy” and “separation expectancy” and that the relational efficacy scale was a one-factor structure;“relational efficacy”. We found high Item-Total correlation coefficients and internal consistency of each factor. The results revealed that the scores on union expectancy and relational efficacy were the highest and the score on separation expectancy was the lowest in romantic relationships. In addition, the scores of each factor were correlated with other measures (e.g., GHQ12). These findings indicated that the translated scales were highly valid. Therefore, this study suggests that the relational optimism scale and the relational efficacy scale are applicable to Japanese samples.
