Table 1
PCL-5 Individual Scores, Group Means, and RCI Analysis Values.
* All criteria met for positive screen for PTSD based on PCL-5 scoring (met minimum clinical criteria for each PTSD cluster and obtained a total score for >32).
Note: Veteran 5 did not meet the minimum clinical criteria for the PCL-5 cluster C at Time 1, cluster B or C at Time 2, cluster B, C, or E at Time 4, cluster B, C, or E at Time 5, and cluster B, C, D, or E at Time 6. Veteran 6 did not meet the criteria for cluster C at Time 3 and cluster B or C at Time 6. If the absolute value of the RCI is greater than 1.96, the difference in scores between the two intervals is statistically significant at a 95% confidence interval. RCI values signifying a significant increase in scores between given intervals are denoted by (**), and those signifying a significant decrease are denoted by (*).

Table 2
DUSI-R SU subscale individual scores, group means, and RCI analysis values.
Note: Range of scores that can be obtained is between 0 to 100%. DUSI-R scores reflect gradations of severity. As such, cut-off scores for evaluation are not provided. If the absolute value of the reliable change index (RCI) is greater than 1.96, the difference in scores between the two intervals is statistically significant at a 95% confidence interval. RCI values signifying a significant increase in scores between given intervals are denoted by (**), and those signifying a significant decrease are denoted by (*). Further, there was a negative average covariance for Time 5, possibly due to the small sample size or there truly was a negative covariance among the scale items.
