Abstract

CONTEXT:

Treating high-risk substance abusers who are members of minority groups may require varied protocols depending on differences among minority groups.

OBJECTIVES:

To explore cocaine abuse (CA)/ dependence with physiological dependence (CDPD) and posttraumatic stress disorder (PTSD) diagnosis differences between out-of-treatment Hispanic and African American adults, in order to identify cultural differences in how experiences and attitudes affect cocaine use behaviors.

DESIGN, SETTING, AND PARTICIPANTS:

This study uses data collected between February and November 2000, as part of a three-year longitudinal study. A cohort of 347 out-of-treatment, Hispanic and African American cocaine-using adults from the Houston metropolitan area were interviewed to measure differences between cocaine users who are dually diagnosed and those that are not.

MAIN OUTCOME MEASURES:

Meeting the Diagnostic and Statistical Manual of Mental Disorders, 4th ed. criteria for dual diagnoses of CA/PTSD or CDPD/PTSD.

RESULTS:

For the dual diagnoses categories, 102 (29%) participants met the requirements for CA/PTSD or CDPD/PTSD. Logistic regression models were used, with CA/PTSD and CDPD/PTSD as the dependent variables. Age, race, gender, and income were used as the independent variables. Results indicate that individuals with higher income have a greater probability of developing CA/PTSD (beta = 0.919, p < 0.05). For both dual diagnoses categories of CA/PTSD and CDPD/ PTSD, results indicate that being female increases the likelihood of developing both of these dual diagnoses, (beta = 2.106, p < 0.05) or (beta = 2.510, p < 0.05). However, being an older female decreases the probability that an individual would develop these dual diagnoses (beta = -2.227, p < 0.05) (beta = -2.577, p < 0.05).

CONCLUSIONS:

No differences were found for race/ethnicity among the dually diagnosed Hispanics and African Americans, however, gender differences were found. Being female increases an individual's probability of developing a dual diagnosis of CA/PTSD or CDPD/PTSD. In addition to being female, being a young female further increases an individual's probability of being dually diagnosed.
