Definitions:

Specifiers

Further descriptors of a patient’s condition that capture the natural variation in the expression of affective disturbances, and therefore increase the specificity of diagnoses by conveying important information about salient features that might be otherwise overlooked. For example, one specifier used in conjunction with a diagnosis of major depressive disorder is “with melancholic features.”

Specific Phobia
