Data were collected using the Loneliness Scale (UCLA), Love Attitudes Scale (LAS), Satisfaction with Love Life Scale (SWLLS) and a Demographic Information Form. Analyses showed that there were no gender differences in loneliness. Significant gender differences were found on ludic, males were more in their love styles than were females. Loneliness was negatively associated with Eros, Storge and Pragma love styles, and with satisfaction with love life.
