Final answer:
The definition of 'deviation from mental health' as a marker of abnormality tends to neglect cultural diversity, failing to consider how different societies conceptualize and deal with mental health.
Step-by-step explanation:
One implication and development (I+D) present in "deviation from mental health" as a definition of abnormality is that it neglects cultural diversity. This concept of abnormality based on mental health standards often considers behaviors, thoughts, and feelings as abnormal if they deviate from the society's norms without accounting for cultural variations and unique conceptualizations of distress across different societies. The inclusion of cultural concepts of distress (CCD) in manuals like the DSM-5 represents an ongoing effort to better understand and characterize mental health issues within a cultural context, emphasizing that interpretations of abnormality may vary significantly across cultures.
