This study was carried out to find out the factors that influence the level of problem drinking of public aid recipients. The sample of this study consisted of 195 public aid recipients living in D and G cities. It was found that drinking is serious among the public aid recipients of which one third are in the state of problem drinking, alcohol abuse, or alcohol dependent. The hierarchical regression analysis revealed that first-drinking under the age of 19, self-esteem, religion, depression, and sex are the factors affecting the problem drinking of public aid recipients. Accordingly, it is necessary to develop a program considering these factors to prevent problem drinking of public aid recipients.
