Abstract: A screening tool according to the present invention is utilized to evaluate a subject for the presence of a mental disorder. The subject is requested to rate various aspects or categories of their mood, preferably within the range from zero to ten. A total score is determined based on the responses and applied to a color coded chart having particular colors associated with various numeric ranges. The color associated with the numeric range encompassing the total score provides an indication and/or severity of the disorder. The tool may be utilized for various disorders (e.g., depression, attention deficit disorder, dementia, etc.), where the tool may include particular aspects, scales and/or questions corresponding to a particular disorder. The tool may be further utilized at periodic or other intervals to determine subject progress with respect to the disorder in response to medication, therapy and/or other treatment.
