This study looked at using Self Management Technique (SMT) to promote self-disclosure of Sero status in Kwara State, Nigeria. A pre-test, post-test and control group quasi experimental design using a 2x2x2 factorial matrix was adopted. Sixty participants were sampled by balloting from two HIV/AIDS screening centres. Four instruments were used such as Demographic data of the participants, Multidimensional AIDS Anxiety Questionnaire (MAAQ), Self-disclosure Subscale (SDSC) and Eysenck Personality Questionnaire (EPQ). The data were analyzed using ANCOVA and t-test at 0.05 level of significance. The results showed that SMT was effective in enhancing self-disclosure of HIV positive individuals and extroverted personality individuals benefited more in the psychotherapy than introverted persons while male participants benefited more than their female counterparts. Based on the results, it's then recommended that psychotherapists should be freely disposed to the use of this therapy to enhance social relationship/interaction between their clients/patients.
