查询词典 underrepresentation

The limitations of the study include underrepresentation of homeless, institutionalized, and non–English-speaking older adults; possible issue with stigma, whereby older adults with mental illness might be less inclined to participate in a mental health survey; and a lay-administered interview rather than a clinically administered assessment.
