Individual differences in the paradoxical thought rebound effect (incr
eased thought expression following attempted thought suppression) were
examined in two studies. In these two studies, the majority of Ss did
not evidence thought rebound and, in both studies, it war found that
a measure of thought rebound was correlated with other variables. In S
tudy 1, a four-factor regression model predicted thought rebound (R(2)
= 0.1477). The significant predictors were: (1) ACT Composite (higher
ACT predicted more rebound); (2) gender; (3) thought intrusion freque
ncy during suppression; and (4) the interaction of gender and thought
intrusion frequency (for male Ss only, more thought intrusions during
suppression predicted more rebound). In Study 2, a replication regress
ion model (R(2) = 0.1408) cross-validated the ACT effect observed in S
tudy 1. A Study 2 extension model (R(2) = 0.2154) found the following
significant predictors of thought rebound: (1) obsessionality (less ob
sessionality predicted more rebound); (2) trait anxiety (less anxiety
predicted more rebound); (3) race (whites rebounded more than blacks);
(4) gender; (5) 16 PF independence; and (6) the interaction of gender
and 16 PF independence (for male Ss only, more independence predicted
more rebound). The implications of these results for thought rebound
theory are discussed. Copyright (C) 1996 Elsevier Science Ltd.
