PTSD: post-traumatic stress disorder, OCD: obsessive compulsive disorder.
aMissing data: marital status (n = 5, 1 for dissociative), employment (n = 15, 4 dissociative) education (n = 10, 2 dissociative), income (n = 39, 11 dissociative), treatment (n = 4, 2 dissociative).
bThe numbers of total comorbid diagnoses exceed original sample size due to multiplicity.
