Final answer:
The issue with 'failure to function adequately' as a definition of abnormality is that it does not address the role of societal norms, ignoring cultural relativity and unique societal standards on what is considered normal or abnormal.
Step-by-step explanation:
What is one more issue with "failure to function adequately" as a definition of abnormality? Among the options provided, the correct criticism is b. It does not address the role of societal norms. This definition of abnormality focuses on how an individual copes with everyday life and whether they can function without experiencing excessive distress or discomfort. However, it fails to consider how societal norms influence perceptions of what is considered adequate functioning. For instance, certain behaviors might be viewed as abnormal in one culture but completely normal in another. Therefore, not addressing the role of societal norms means that the definition may not fully account for the cultural relativity of abnormality.
Societal norms play a critical role in defining what is considered normal or abnormal within a community or society. Cultural concepts of distress (CCD) illustrate this by showing how different cultures experience and communicate mental health issues. Therefore, a comprehensive understanding of abnormality must consider societal and cultural norms to avoid imposing a universal standard that may not apply across different societies.
