Adults (23) and children (20) with hemophilia, all on self-treatment, participated in the present study. They were interviewed as to how they perceive the effects of self-treatment upon various aspects of their life. The ability to treat themselves was perceived by patients as a great improvement over their previous treatment regimes for which they had had to go to hospital. Of the adult patients, 12 had participated in previous studies concerned with the social and psychological aspects of hemophilia. The analysis of the responses of these 12 patients showed that self-treatment is perceived so positively that some of the patients'' earlier perceptions were distorted to correspond with their present and more optimistic perceptions of their condition. The number and type of psychosomatic symptoms was unchanged by self-treatment and the unemployment rate has not decreased.
