Table 5 The relationships between quartile-divided general self-efficacy and posttraumatic stress reactions

From: General self-efficacy and posttraumatic stress after a natural disaster: a longitudinal study

  IES-R at 6 months Mean (SD) IES-R at 2 years Mean (SD) Changes in IES-R (2 years – 6 months) Mean (SD)a
1st quartile GPSES (n = 130) 1.48 (0.96) 1.33 (0.94) −0.15 (0.68)
2nd quartile GPSES (n = 166) 1.22 (0.79) 1.21 (0.79) −0.01 (0.58)
3rd quartile GPSES (n = 156) 1.06 (0.74) 1.01 (0.77) −0.05 (0.50)
4th quartile GPSES (n = 165) 0.85 (0.74) 0.77 (0.72) −0.08 (0.51)
Sign test F (3, 613) = 15.85, p < .001 F (3, 613) = 13.56, p < .001 F (3, 613) = 1.57, p = .20
Post hoc 1 > 2, 3 and 4 1 > 3 and 4 None
2 > 4 2 and 3 > 4
  1. Significant differences between quartiles were tested with one-way ANOVAs based on multiple imputed data. The Bonferroni test was used post hoc to investigate which quartiles were significantly different from each other
  2. GPSES General Perceived Self-Efficacy Scale, IES-R Impact of Event Scale-Revised
  3. aNegative figures indicate a decrease in posttraumatic stress reactions from 6 months to 2 years post-disaster
