INTRODUCTION:

Although impairment in the quality of life is common among cocaine dependent patients, there are but a few researches about the interaction between addiction and quality of life.

OBJECTIVE:

To study different parameters of quality of life in a sample of cocaine dependent patients and to compare patients with or without dual diagnosis. Also, to promote the importance of subjectivity in the quality of life and to propose to incorporate patients' self-perception into their treatment.

METHOD:

Three diagnostic interviews were administered (SCID-I, SCID-II and PRISM) and a quality of life questionnaire (SF-36) was applied between two different patient groups: Group I (cocaine dependent patients) and Group II (cocaine dependent patients with other mental disorder).

RESULTS:

Patients diagnosed with dual disorders (Group II) showed broader differences in perceptions of their quality of life in comparison with their clinicians. The perception of quality of life may vary depending on the presence and severity of mental disorders, and these different appreciations may explain the difficulties that clinicians face in understanding their patients' expectations and motivations.

DISCUSSION AND CONCLUSION:

A systematic evaluation of the subjective quality of life should be included in the management of cocaine dependent patients in order to more accurately understand the patients' perception of their treatment, motivations and expectations.
