Relationship between sensation seeking, alcohol problems and bulimic symptoms: a community-based, longitudinal study.

PURPOSE: The association of bulimic symptoms with sensation seeking is uncertain; however, both behaviors have been linked to alcohol problems. We assessed in a longitudinal, community-based setting whether sensation seeking in adolescence is associated with bulimic symptoms in early adulthood, also accounting for alcohol problems.

METHODS

Finnish men (N = 2000) and women (N = 2467) born between 1974-1979 completed Zuckerman's sensation seeking scale (SSS) at age 18. Alcohol problems (Malmö-modified Michigan alcoholism screening test (Mm-MAST) and bulimic symptoms [eating disorder inventory-2, bulimia subscale (EDI-Bulimia), population and clinical scoring systems] were defined at age 22-27. We examined relationships between SSS, Mm-MAST, and EDI-Bulimia using Pearson's correlation coefficient (r) and linear regression.

RESULTS

Alcohol problems were moderately correlated with sensation seeking and bulimic symptoms (population scoring) among women and men (r = 0.21-0.31). The correlation between sensation seeking and bulimic symptoms (population scoring) was weak among men (r = 0.06, p = 0.006) and even weaker and non-significant among women (r = 0.03, p = 0.214). Adjustment for alcohol problems removed the association between sensation seeking and bulimic symptoms among men. Furthermore, there were no significant correlations between sensation seeking and bulimic symptoms when assessing EDI-Bulimia clinical scoring.

CONCLUSION

Sensation seeking and bulimic symptoms were not associated among women. The association between sensation seeking and bulimic symptoms among men was entirely attributable to increased alcohol problems among those with higher sensation seeking. While this association may be important on the population level, its clinical significance may be minor.

LEVEL OF EVIDENCE: Level III, well-designed cohort study.
