The current study aims to compare the expectations and purpose of marriage of women and girls in Shiraz. In this study, 180 participants (90 women and 90 girls) were selected to participate from the available population. The instruments to collect data were questionnaires and a structured interview. The participants completed the Socio-Demographic Characteristics Form and the Marital Attitude and Expectation Scale (36-item). To analyze the data, independent t-test and chi square were used. The analysis revealed statistically significant differences between groups in terms of marital expectations and its three main subscales including Intent to Marry, General Attitudes towards Marriage, and Aspects of Marriage. In sub-scales, the difference between married women and single girls in negative attitudes toward marriage, fear/doubts and love was significant. However, significant differences in the other subscales such as respect, trust, finances, meaning and physical intimacy weren't found. Moreover, significant differences were found in the purpose of marriage of women and girls, in emotional, religious, sociocultural, financial, and idealistic purposes (P<0.01), but the difference wasn't significant in sexual purpose. The overall result of this study suggests that women tend to have higher expectations of marriage than girls and the married women and girls' purposes of marriage were different.
