Analyses were conducted in two stages, including race, childhood trauma, and a race by childhood trauma interaction term in the first model. In the second step, dichotomously coded indicators of SES and continuous variables representing neighborhood factors were added and interaction terms representing race and childhood trauma by each of the SES and neighborhood variables were tested one at a time. Statistically significant interaction terms and all main effects were retained in the final models.
