In this study psychosocial markers of smoking were investigated. Psychosocial process includes changes in emotions, personality, identity and relations with others.  In the current study three-dimensional identity model, big five personality dimensions, family models of independence and interdependence, and attachment theory were focused. The purpose of the current study was to determine psychosocial markers (identity statuses, personality dimensions, self construals and attachment styles) of smoking.

Cross-sectional research design was used in this descriptive study. Participants were 400 youth aged between 17 and 22 years. In order to collect data Fagerstrom Test for Nicotine Dependence, Utrecht-Management of Identity Commitments Scale, Quick Big Five Personality Test, Autonomous-Related Self in Family Scales and finally The Inventory of Parent and Peer Attachment were used. Frequency and percentage values were used to analyze the demographic characteristics of participants. In order to determine relations between variables Pearson Correlation was used.
