PTSD Diagnosis → Intercept | 16.039 | 2.178 | 2.296 | .022 |
PTSD Diagnosis → Growth | 2.779 | 7.794 | .357 | .721 |
Alcohol → Intercept | 2.826 | 4.779 | .591 | .554 |
Alcohol → Growth | 5.865 | 5.352 | 1.096 | .273 |
Cocaine → Intercept | .902 | 5.235 | .172 | .863 |
Cocaine → Growth | 2.059 | 5.862 | .351 | .725 |
Note: PTSD Diagnosis = dichotomously coded variable (1 = met diagnostic criteria for PTSD at first assessment, 0 = did not meet criteria for PTSD at first assessment). Alcohol = dichotomously coded dummy variable representing substance of withdrawal (alcohol = 1, cocaine or cocaine/alcohol = 0). Cocaine = dichotomously coded dummy variable representing substance of withdrawal (cocaine = 1, alcohol or cocaine/alcohol = 0). Together the Alcohol and Cocaine variables represent the 3 drug withdrawal categories (cocaine only, alcohol only, and alcohol and cocaine). Intercept = latent variable representing baseline MPSS score. Growth = latent variable representing change in MPSS scores over time. SE = Standard Error.
