Mental health and functional consequences of meeting symptom criteria for PGD by temporal subtype.

Acute = meeting symptom criteria at 0–6 mo, but not at 6–12 mo, post-loss; Delayed = not meeting symptom criteria at 0–6 mo, but meeting symptom criteria at 6–12 mo post-loss; Persistent = meeting symptom criteria at 0–6 and 6–12 mo post-loss. aThe denominator included those assessed at both 0–6 and 6–12 mo post-loss. bThe denominator included all those assessed at 6–12 mo post-loss, regardless of the 0–6-mo post-loss assessment. cSample sizes (n) varied due to missing data. The first number in the parenthesis represents n for those assessed at both 0–6 and 6–12 mo post-loss, the second number after the colon represents n for those assessed at 6–12 mo post-loss regardless of the 0–6-mo post-loss assessment. *p<0.05; **p<0.01; ***p<0.001. CI, confidence interval; RR, relative risk.
