2-factor correlated model: cognitive impairment (items 1–8) and functional impairment (items 9–13)	205.33/64 = 3.21	0.936	0.922	0.085 (0.072; 0.099)	0.047	16,496.321
3-factor correlated model: intrusive symptoms (items 1–4), reflections on CA (items 5–8) and functional impairment (items 9–13)	135.078/62 = 2.18	0.968	0.959	0.062 (0.048; 0.076)	0.040	16,355.976
