What is คำเตือนกระทบจิตใจ / หมายเหตุเนื้อหา?

They’re often used interchangeably. A trigger warning tends to emphasize potential trauma triggers (e.g., sexual violence), while a content note can be broader and more neutral (e.g., themes of grief). In practice, use clear, neutral wording that informs without sensationalizing.

Be specific about the type of material (e.g., 'contains depictions of sexual assault' rather than vague labels like 'may be upsetting') but avoid describing plot details or outcomes that would ruin surprises. Keep it short, factual, and placed before the content.

Not necessarily. Use notes for material likely to cause strong distress or re-traumatization (violence, sexual coercion, detailed self-harm). Routine mature themes or consensual adult sex can be signaled by rating systems and age checks rather than a trigger warning.
