Background & Aim: The "Theory of attachment" is one of the Contemporary theories for anticipating the mental health in adults. This study aimed to determine the relationship between adults’ attachment styles and attitudes of health behaviors in the city of Shoosh.

Material & Methods: This study was a descriptive correlation study. 300 employees working in shoosh city were selected by census sampling. The supplementary questionnaire of revised adult attachment (RASS) coefficient and self-made questionnaire of healthy attitude and behavior (a=0.75) were used for data collection.

Results: The results indicated that whereas 87% of the respondents showed a healthy attitude, majority of them were reported to have weak healthy behaviors. The frequency of attachment style in 64% of samples was safe and in 28.3% was unsafe. There was no significant relationship between attachment style of people and their healthy attitude and behavior, but a significant, negative relationship between the average values of healthy attitude and behavior with avoidance style was found. The results also showed a significant relationship between the styles of attachment with marital status and the age of samples (p=0.021).
