  7. Why are diagnostic manuals such as the DSM periodically revised?

    • Decreasing patient numbers

    • Reduce sample size
    • Increase reliability
    • Eliminate cultural norms
    • Replace classification manuals

  17. What is a key drawback of using culture-specific diagnostic criteria?
