BMC Psychology

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

	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
Post hoc	2 > 4	2 and 3 > 4	None

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
