Background: Considering Voluntary Function (VF), the purpose of the present study was to prognosticate the addiction potential (AP) among some members of the Iranian Red Crescent Society (IRCS) in Iran. To get the research done, we made use of both correlative and descriptive methods as research methods. Methods: The statistical population of the current study included all youths who have been members of the IRCS. We employed multistage cluster sampling as the sampling method. We recruited 620 active volunteers of the IRCS from 31 province and 175 cities of Iran (48.7% female and 50.1 Male mean age 23.27±3.32, range 14–31 years). Iranian Addiction Potential Scale (IAPS) and Voluntary Function Inventory (VFI) have assisted us in collecting research data. Results: Findings proved that there was a negative significant correlation between the AP and all measurements of VF such as protective enhancement, understanding, career, values, and motives; meaning that the more time youth spent on participating in voluntary activities, the less likely they sought to resort to misusing AP. Findings of the simultaneous-entry multiple regression has proved that volunteerism could prognosticate 15% of changes in the AP as a criterion variable. Conclusions: Due to its positive features, volunteerism played a key role in prognosticating and preventing the AP. Thus, it is incumbent to draw particular attention to this worthy factor.
