THE NEGATIVE CONSEQUENCES OF HEAVY DRINKING AND ASSOCIATED DISRUPTIVE BEHAVIORS FOR SIBLING RELATIONSHIP PERFORMANCE

This study is designed to extend the sociological research on alcohol use and family relationships. We focus specifically on how heavy drinking by a sibling erodes the sibling relationship performance. Using survey data gathered from 339 college students attending a large Southern University, the results indicate that siblings who are heavy drinkers exhibit substantially poorer sibling relationship performance than nondrinking siblings. However, the data also indicate that there is an important factor mediating this link. Once a measure of disruptive behaviors often associated with heavy drinking is controlled, sibling drinking is no longer a significant predictor of sibling relationship performance. Hence, the inverse relationship between sibling drinking and sibling relationship performance is actually accounted for by an underlying association between disruptive behaviors associated with heavy drinking and poor sibling relationship performance. We conclude with a discussion of the limitations of the study and the theoretical implications of the findings, including suggestions for future research in this area.
