Symptom scores were standardized to a mean of 0 and variance of 1.
Based on a multivariate logistic regression model with the four symptom counts predicting the presence versus absence of dissociative symptoms among respondents with 12-month DSM-IV/CIDI PTSD.
Significant difference between mean number of symptoms of re-experiences, avoidance, numbing, and hyperarousal among respondents with versus without dissociative symptoms at the .05 level, two-sided test.
Significant association between the predictor and presence versus absence of dissociative symptoms at the .05 level, two-sided test.
