This study examined dispositional and situative antecedents of vigilan
t and avoidant coping behavior. Seventy-two subjects were classified i
n coping style on the basis of their responses to the vigilance and co
gnitive avoidance scales of the Mainz Coping Inventory (MCI, Krohne, 1
989), and alternatively, on their trait anxiety and defensiveness scor
es (cf. Weinberger, Schwartz, & Davidson, 1979). In a subsequent labor
atory task, subjects were exposed to various conditions of predictabil
ity of an aversive event. In anticipation of an aversive loud tone, co
ping behavior was operationally defined as choosing to listen either t
o a warning channel (i.e., vigilance) or instead to music (i.e., avoid
ance). Probability of occurrence of a warning signal while listening t
o the warning channel varied across trials, being either 0%, 33%, 66%,
or 100%. Subjects were exposed to each level and were informed about
the respective probability in advance. In general, listening to the wa
rning channel increased with an increase in the probability of the war
ning signal. However, four groups of subjects who differed in their pa
ttern of coping behavior across trials were observed: rigid-avoidant c
opers (always listening to music), rigid-vigilant copers (always monit
oring the warning channel), flexible copers (switching from music to w
arning channel with increasing probability of warning), and inconsiste
nt copers (vacillating between music and warning channel regardless of
probability of warning). Coping style classifications did not show su
bstantial associations with coping behavior. However, subjects demonst
rating the inconsistent coping pattern scored high on trait anxiety.
