Alexithymia and Self-Esteem in a Sample of Opioid Dependent Males: a Controlled Study.

The aim of this study was to evaluate the prevalence of alexithymia in opioid dependents compared to the controls and to examine the relationship between alexithymia and depression, anxiety, and self-esteem in opioid dependents. Fifty male heroin-dependent outpatients who completed the detoxification process according to DSM-IV TR diagnostic criteria and 50 control subjects matched for age, gender, and education status who do not abuse heroin or any other substances were included in the study. Subjects were interviewed by using the Structured Clinical Interview for DSM-IV (SCID-I). Variables of interest were assessed according to Toronto Alexithymia Scale-20 (TAS-20), Rosenberg Self-Esteem Scale (RSES), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI). Forty-two percent of the opioid dependents were estimated as alexithymic according to the cut-off scores of TAS-20 (> 61), while this ratio was 10% for the control group. The mean TAS-20 score in the dependent group was significantly higher than in the control group. BDI, BAI, and RSES scores were also found to be significantly higher in the dependent group, particularly in the alexithymic opioid dependent group. There were significant positive correlations between TAS-20 and BDI, BAI, and RSES scores. Further studies are needed to understand the negative effects of alexithymia and lower self-esteem on opioid dependence. [ABSTRACT FROM AUTHOR]
