Schizophrenia is a complex psychiatric disorder with a characteristic disease course and heterogeneous etiology. While substance use disorders and a family history of psychosis have individually been identified as risk factors for schizophrenia, it is less well understood if and how these factors are related. To address this deficiency, we examined the relationship between substance use disorde...

Latent Classes of Substance Use in Adolescent Cannabis Users: Predictors and Subsequent Substance-Related Harm

Cannabis use is highly prevalent in late adolescence, but not all users experience significant negative consequences. Little information is available to identify the substance use patterns and risk factors of users who are at greater risk of experiencing negative consequences. In this prospective study, we aimed to empirically identify latent classes of substance use in adolescent cannabis user...

Adolescent substance use.

Using latent class and latent transition analysis to examine the transtheoretical model staging algorithm and sequential stage transition in adolescent smoking.

Data on stage of change was collected between 1997-1999 on 4125 adolescent nonsmokers and smokers from central England who completed two versions of the stage of change algorithm for smoking acquisition and cessation. The fit of the latent variable defined by the spiral of change to adolescents' responses to the staging questions was examined using latent class analysis. Whether a model of sequ...
