The interactive effect of event centrality and maladaptive metacognitive beliefs on posttraumatic stress symptoms and posttraumatic growth.

OBJECTIVE

Event centrality, the extent to which a traumatic event becomes a reference point for understanding the world and one's role in it, is related to both posttraumatic stress (PTS) symptoms and posttraumatic growth (PTG). Given that higher event centrality is associated with both of these seemingly disparate postevent trajectories, research on potential moderators of these relationships is needed to better understand the conditions under which event centrality relates to one or both outcomes. Maladaptive metacognitive beliefs (i.e., beliefs about thinking, Wells & Matthews, 1994, 1996) might be one individual difference factor that influences the degree to which event centrality is related to PTS symptoms and PTG.

METHOD

In a laboratory session, undergraduate students ( = 149) completed self-report measures of event centrality, maladaptive metacognitive beliefs (negative and positive), PTS symptoms, and PTG. Analyses were conducted using structural equation modeling in order to account for shared variance between PTS symptoms and PTG.

RESULTS

As predicted, the positive relationship between event centrality and PTS symptoms became increasingly stronger as maladaptive metacognitive beliefs increased (i.e., both positive and negative metacognitive beliefs). The positive relationship between event centrality and PTG was stronger as maldaptive negative, but not positive, metacognitive beliefs decreased.

CONCLUSIONS

Study findings suggest that treatments designed to reduce maladaptive metacognitive beliefs could lead to reductions in PTS symptoms and increased opportunity for PTG among those with highly central traumatic events. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
