Partial correlations between cognitive domains and PTSD symptoms while controlling for duration of PTSD and depression status

	PTSD symptom severity measured with the PCL-5
Cognitive domain	Total score	Cluster B	Cluster C	Cluster D	Cluster E
Information processing speed	−.24	−.44*	−.52**	.18	−.15
Attention and working memory	−.38	−.51**	−.26	−.05	−.38
Executive functions	−.28	−.42*	−.30	>.01	−.23
Lexical access	.03	−.06	−.04	.23	−.07
Verbal learning	−.29	−.39	−.02	−.07	−.34
Verbal memory	−.07	−.19	.16	.03	−.11

The association is statistically significant, *p < .05. **p < .01; Cohen’s guidelines (1988) can be used to interpret the magnitude of these correlations (small: r = .10; medium: r = .30; large: r = .50)
