Final answer:
Defining psychopathology based on failure to function adequately is subjective and fails to recognize individual experiences, which can lead to underdiagnosis or misdiagnosis.
Step-by-step explanation:
One limitation of failure to function adequately as a definition of psychopathology is that this criterion is highly subjective. What may be considered a dysfunctional behavior or failure to cope in one culture or society can be quite normal in another. Also, some individuals may function effectively in society despite experiencing a high level of psychological distress; for instance, high-functioning individuals with depression or anxiety may still manage to fulfill their roles at work and at home. Judging psychopathology based on this criterion alone may fail to recognize the internal experiences of an individual and could lead to underdiagnosis or misdiagnosis.
