From this point of view, the aim of the study is to examine the effect of family climate and attachment style on the prediction of adults' relationship role expectations.The sample of the study consists of 256 women and 103 men who are legally of age living in Turkey. Based on the purpose of the research, the data were collected with the Personal Information Form, Marriage Role Expectation Scale, the Family Climate Scale and the Three-Dimensional Attachment Styles Scale. Correlations between variables were examined and multiple regression analysis was performed. According to the results of the research, relationship role expectations showed correlations with individuals' age, gender, number of siblings, family type, marital status, cohabitants and romantic relationship status. It was seen that the only variable predicting egalitarian role expectation was gender.
