a
Two-sided P values less than .05 were considered statistically significant; analyses used analysis of variance for continuous variables and χ2 tests for categorical variables. GAD-7 = Generalized Anxiety Disorder 7-Item Scale, higher score indicates greater anxiety; IES = Impact of Events Scale, higher score indicates greater intrusive thoughts; PHQ-2 = Patient Health Questionnaire 2 item, higher score indicates greater depressive symptoms; PHQ-9 = Patient Health Questionnaire 9 item, higher score indicates greater depressive symptoms.
b
P for 0 vs 1, 2, 3.
c
P for currently vs not.
