This study was designed to examine the effects of deliberate suppression of trauma-related thoughts in 44 individuals who were diagnosed with posttraumatic stress disorder (PTSD+) and 26 individuals who were not (PTSD–) following a motor vehicle accident (MVA). In an effort to resolve discrepancies in the literature, the PTSD– group was selected from the same help-seeking population as the patient group. Measures included the percentage of MVA-related thoughts, mood, perceived controllability of thoughts, and physiological arousal (heart rate, skin conductance, and two measures of facial EMG). Contrary to hypothesis, both PTSD+ and PTSD– groups showed a rebound in trauma-related thoughts following deliberate thought suppression. This rebound was associated with increases in negative affect, anxiety, and distress and diminished perceptions of controllability over thoughts. Examination of the physiological measures did not mirror the pattern noted for trauma-related thoughts, although the data suggest that suppression was associated with higher levels of frontalis EMG. The current study indicates that help-seeking individuals who are distressed about their psychological state following a serious MVA will show a rebound in MVA-related thoughts, irrespective of PTSD diagnosis. Implications for the study of thought suppression as a potential maintaining factor for trauma-related problems are discussed, with suggestions for future research.

Examination of the percent MVA-related thoughts revealed a significant phase effect, F(2, 136) = 31.09, p < .0001, partial η2 = .31, and a significant group effect, F(1, 68) = 10.7, p < .002, partial η2 = .14. The Group × Phase interaction term was not significant, contrary to hypothesis (see Figure 1). Follow-up of the significant phase effect indicated that participants showed significantly lower levels of MVA-related thoughts during the Suppression phase (mean 12.1%, SD 22.06) relative to the Monitor 1 phase (mean 20.5%, SD 30.04, p < .05). Participants showed a rebound in MVA-related thoughts during the Monitor 2 phase (mean 46.1%, SD 33.30), which was significantly different from both the Suppression and Monitor 1 phases (p < .05). Thus, participants appeared to suppress MVA-related thoughts during the Suppression phase, which was followed by a rebound in these thoughts during the Monitor 2 phase. Follow-up of the significant group effect indicated that the PTSD+ group reported a higher percentage of MVA thoughts overall (mean 31.9%, SD 31.11), relative to the PTSD– group (mean 16.6%, SD 19.24, p < .05). 3
