  1. a1 and a2 represent the effects of household violence and multiple ACEs on CSEs, compared to low ACEs; b represents the effect of CSEs on psychological distress; c1' and c2' represent the relative direct effects of household violence and multiple ACEs on psychological distress, relative to low ACEs; a1*b and a2*b represent the relative indirect effect on psychological distress through CSEs for household violence and multiple ACEs, compared to low ACEs
  2. CSEs current stressful events, ACEs adverse childhood experiences, CI confidence interval, SE standard error
