When many illnesses seem to occur at the same time; that is, a specific set of symptoms could qualify an individual for more than one diagnosis. This phenomenon is called
A) co-incidence.
B) dual diagnosis.
C) prevalence.
D) comorbidity.
Answer: D
Rationale: Comorbidity is the presence of two disorders simultaneously, or the presence of a second disorder that affects the one being treated. Comorbidity rates have led some psychologists to suggest that the DSM-IV identifies too many different types of disorders. The term dual diagnosis is used specifically to refer to a comorbid substance abuse problem.
