Objective

We aim to evaluate the attachment style, sexual orientation and biological sex in their relationship with the gender role, i.e., masculinity and femininity.

Methods

We recruited a convenience sample of 344 (females=207; males=137; mean age=26.33±6.59) subjects and we administered them a psychometric protocol composed of Bem Sex Role Inventory (BEM), Attachment Style Questionnaire (ASQ) and the Kinsey Scale to categorize the sexual orientation. We performed a further bi-categorization based on the first two points of Kinsey Scale (heterosexuality) and the other six points (non-heterosexuality).

Results

According to our categorization, we found that 38 individuals declared to be non-heterosexuals and 306 heterosexuals. We found no statistically significant differences in the scores referred to attachment styles and gender role between heterosexuals and non-heterosexuals. Regression analysis revealed that confidence and relationship as secondary of ASQ have a predictive role towards a higher score of masculinity (β=.201; p=.000 and β=.209; p=.000, respectively), while need of approval has a negative role on it (β=-.232; p=.001). Moreover, we found that to be a male is predictive for masculinity (β=.206; p=.0000). Also, femininity is predicted by confidence scale of ASQ (β=.170; p=.002), and need of approval (β=.154; p=.03). Instead, relationship as secondary plays a negative role on femininity (β=-.194; p=.0001). None association between non-heterosexual orientation and gender role was found.
