Many factors affect interpersonal attractions. According to Social psychological studies, pleasant and
unpleasant odors of individuals and environment, could be one of them. This study aimed to explore the impact of
pleasant and unpleasant odors on interpersonal and social attractions. In addition, different situations in which these
influences might be stronger, and the differences between men and women, also were examined. Odor Awareness
Scale (OAS) was used in this research. Its validity and reliability were measured for the first time in Iran. Also,
demographic questionnaire was used. The research population was university of Isfahan students in 2013. A sample
of 155(73 men) was chosen by simple random sampling method. Data were analyzed by t-Test and correlation. The
OAS's social and interpersonal relations items were analyzed. All items of the scale were significantly correlated with
the scale's total sum( P < 0.001 ) The gender differences were significant, only in positive sub-scale's items( P < 0.05 )
but, no significant difference was found between men and women in negative sub-scale's items. Pleasant odor would
increase interpersonal attraction and unpleasant odor would decrease it. Interestingly, attraction reduction due to
unpleasant odors are more than attraction increases while pleasant odors are present. Pleasant odors have more
influence on women, but the effects of unpleasant odors, are the same for both sexes.
