Using addiction severity profiles to differentiate cocaine-dependent patients with and without comorbid major depression.

This study compared pretreatment addiction severity profiles of 339 abusers in three diagnostic groups: cocaine dependence only (CO), cocaine dependence with substance-induced major depression (SIMD), and cocaine dependence with independent major depression (IMD). Depressed subjects reported more severe problems than non-depressed subjects across numerous domains, regardless of diagnostic etiology. These findings support the need for specialized treatment approaches targeting depressive symptoms or life stress for cocaine-dependent patients with IMD or SIMD, though patients with IMD may require additional attention for chronic and comorbid psychiatric and medical problems.
