PIP: This article explores the introduction of a unified theory for HIV/AIDS counseling. Counseling intervention adopted by the WHO Global Program on AIDS was guided and informed by the behavioral theory of counseling. This approach was aimed at preventing the spread of infection and providing psychosocial support to those who are already sick. It is argued that counseling based on behavioral theory provides a limited therapeutic intervention and fails to meet all the needs that are associated with HIV/AIDS issues. Thus, other theoretical sources were explored which resulted to a unified theory of counseling that drew upon three main sources including behavioral, psychoanalytic, and humanistic theories. It is argued that future counseling interventions should be redirected from a disease-centered approach to a person-centered approach. Introduction of the unified theory can be facilitated by the use of the self-concept model. In conclusion, the unified theory provides the therapeutic foundation upon which a comprehensive counseling intervention can be based.
