Is a Specific Subtype of Childhood Trauma Driving the Association Between Childhood Trauma and Clinical Characteristics?
Multilevel regression analyses were performed to investigate whether specific underlying childhood trauma subtypes were driving the associations with clinical characteristics (Table 3). Only sexual abuse and emotional abuse were independently associated with earlier age at onset. Moreover, as shown in step 2, this association was still significant after gender was added into the model. Emotional and sexual abuse were independently associated with increased frequency of a history of suicide attempt and remained so after gender and duration of illness were introduced into the model. Sexual abuse was the only statistically significant predictor of rapid cycling. Sexual abuse was still associated with rapid cycling after gender and duration of illness were added into the model.
