Probability of endorsing comorbid conditions by latent class
| Latent Class 1 | Latent Class 2 | Latent Class 3 | |
|---|---|---|---|
| N = 660 (54%) | N = 234 (19%) | N = 325 (27%) | |
| Alcohol dependence | .05 (SE = .02) | .02 (SE = .03) | .83 (SE = .06) |
| Substance dependence | .04 (SE = .01) | .08 (SE = .03) | .37 (SE = .03) |
| Cannabis abuse | .03 (SE = .02) | .82 (SE = .06) | .69 (SE = .05) |
| Alcohol abuse | .10 (SE = .02) | .70 (SE = .07) | .02 (SE = .01) |
| Substance abuse | < .01 (SE = .01) | .44 (SE = .05) | .01 (SE = .01) |
| Major depressive disorder1 | .23 (SE = .02) | .19 (SE = .03) | .21 (SE = .03) |
The probability of endorsing indicator variables differed from class to class. Individuals in Latent Class 1 had the highest probability of endorsing symptoms of depression. Individuals in Latent Class 2 had the highest probability of endorsing illegal substance and alcohol abuse, whereas individuals in Latent Class 3 endorsed disorders of drug and alcohol dependence. The probability of endorsing cannabis abuse was high in Latent Class 2 and in Latent Class 3.
