Method: Diagnostic questions were assessed by the DSM-IV checklist. Data were analyzed by the item response theory and the multiple indicators multiple causes method procedures. Results: Criterion symptoms of alcohol and marijuana dependences exhibited a high level of internal consistency. All individual symptoms showed good discrimination in distinguishing alcohol or marijuana users between high and low severity levels of the continuum. In both groups, "withdrawal" appeared to measure the most severe symptom of the dependence continuum. There was little evidence of measurement nonequivalence in assessing symptoms of dependence by gender, age, race/ethnicity, and educational level. Conclusions: These findings highlight the clinical utility of the DSM-IV checklist in assessing alcohol- and marijuana-dependence syndromes among treatment-seeking substance users.Citation DetailsTitle: An item response theory modeling of alcohol and marijuana dependences: a national drug abuse treatment clinical trials network study.(Clinical report)Author: Li-Tzy WuPublication: Journal of Studies on Alcohol and Drugs (Magazine/Journal)Date: May 1, 2009Publisher: Alcohol Research Documentation, Inc.Volume: 70 Issue: 3 Page: 414(12)Article Type: Clinical reportDistributed by Gale, a part of Cengage Learning |
