 The improvement of mental disorders may have an effect on multiple domains of an individual's life which could be captured only through a comprehensive measurement.For example, the treatment of a phobia may reduce fear (mental health index), which could lead to the improvement of social relations (social relations index) and, in turn, performance at work, resulting in an increase in salary (financial index).Hence, in order to detect all implications of a treatment (e.g., for a phobia), a comprehensive measurement across multiple domains of an individual's life is needed.
