Objective: Survey research suggests that there are few, if any, gender
differences in the types and frequency of informal drunk-driving inte
rvention. This contrasts sharply with laboratory studies of helping be
havior which report that men are more likely to help than are women. T
he present study examined the frequency and success rate of several di
fferent types of informal drunk-driving intervention for women and men
. The influence of the gender of the intervenor and the intoxicated in
dividual and the intervenor's familiarity with the individual on the u
se and success of the different interventions were also examined. Meth
od: Students (N = 388) at a major West Coast university completed a dr
inking and driving questionnaire. Of these subjects 303 (78%) reported
having been in a DUI situation within the last year, and 68% of these
students (n = 206) who reported having intervened at least once in th
e past year were used in the present study. Results: Women were just a
s likely as men to intervene. There were few gender differences in the
frequency and success rates of the different types of intervention ex
amined. Familiarity with the intoxicated individual increased the freq
uency and success of intervention. However, intervention with stranger
s occurred under certain circumstances. Conclusions: These data indica
te that there are few gender differences in the use and success rate o
f different types of informal drunk-driving intervention. However, sin
ce the interventions examined in this study were determined a priori,
gender differences may still be operative. There is some research evid
ence that suggests that men and women approach potential drunk drivers
differently. Furthermore, the role of familiarity in drunk-driving in
tervention needs to be further examined.
