  • Please note that only significant mediations were reported (p<0.05).

  • Prop. Mediated=proportion of effect of the patient’s class on the Y variable that goes through the mediator (calculated as ACME/TE).

  • ACME, average causal mediation effect; ADE, average direct effect; DTS, Davidson Trauma Scale; GSI, Global Severity Index; PSDI, Positive Symptom Distress Index; TAO, turning against objects; TAS, turning against self; TE, total effect (direct+indirect).
