Pretreatment status variables and treatment implementation for cocaine misuse: a latent variable structural model

P Roldan-Vandervort

    Substance Use & Misuse
    |January 24, 1998
    PubMed
    Summary

    This study evaluated a structural equation model for cocaine misuse treatment outcomes. The model fit the data well, but discharge rates were not significantly linked to initial cocaine misuse severity.

    Area of Science:

    • Addiction research
    • Psychometrics
    • Treatment outcome studies

    Background:

    • Cocaine misuse poses significant public health challenges.
    • Effective treatment outcome research requires robust statistical models.
    • Latent variable structural equation modeling offers a sophisticated approach to analyzing complex treatment data.

    Purpose of the Study:

    • To assess the applicability of a latent variable structural equation covariance model in cocaine misuse treatment outcome research.
    • To evaluate the goodness-of-fit for three distinct structural models using real-world treatment data.
    • To explore relationships between various factors and treatment success in cocaine misusers.

    Main Methods:

    • A sample of 206 individuals receiving drug misuse treatment in Nevada was analyzed.

  • Fourteen variables were incorporated into structural equation models.
  • Goodness-of-fit indices, including Comparative Fit Index (CFI) and chi-squared tests, were used to evaluate model performance.

    • Main Results:

    • A structural equation model demonstrated adequate fit to the data (CFK = .956).
    • The chosen model indicated that discharge rates did not significantly vary based on the severity of cocaine misuse at the time of admission.
    • The statistical model provided a viable framework for analyzing cocaine misuse treatment data.

    Conclusions:

    • Latent variable structural equation modeling is a useful tool for cocaine misuse treatment outcome research.
    • Treatment effectiveness, as indicated by discharge rates, may not be solely determined by initial cocaine misuse severity.
    • Further research should explore other predictors of treatment success in cocaine misuse populations.
