The relationship between personality character and sexual desire of Methadone Replacement Therapy in heroin dependence subjects

The relationship between personality character and sexual desire of Methadone Replacement Therapy in heroin dependence subjects

It is well known that heroin addiction has many impacts on the patient in the physical and psycho-social aspects. The main purpose of this research is trying to understand whether or not methadone replacement therapy has differing effects on the demographics and personalities in the population of heroin users. Furthermore, we discuss the effect of methadone replacement therapy on sexual desire. 

Methods: In this purposive sampling study, we included the descriptive research method and case control study. Data was collected for Eysenck Personality Questionnaire (EPQ) and Sexual Desire Inventory (SDI).

Results: The sample population consisted of 139 male and 27 female subjects. 65 male and 10 female subjects were then followed monthly for three months for further analysis of changes in sexual desire. The research showed a moderately direct correlation between extroverts of the EPQ scale and sexual desire (p < .05). Further analysis showed the frequency of sexual needs, sexual desire, level of education, and paternal care to be predicting factors for the factors of re-enrolment in the study. Moreover, upon using generalized linear regression analysis (GEE) on cases who received methadone treatment, a direct and improving correlation was found in sexual desire of cases pre and post treatment with statistical significance (p = 0.018). Furthermore, the results showed that sexual desire is affected by gender and level of education (p = 0.01), years of usage (p = 0.002), and frequency of drug injection (p = 0.001).

Conclusion: Therefore, we can predict that the issue of decreased sexual desire experienced by heroin users may be improved after methadone treatment; moreover, after carrying out clinical evaluations and primary methadone treatments, we have reached the preliminary conclusion that, in the future, efficacious treatment may be anticipated in such patients without neurotic personality and for heroin users experiencing sexual desire problems.
