(A)外顯逃避（overt avoidance）與無效安全信息（ineffective safety signals）
(B)外顯逃避（overt avoidance）與安全型行為（safety behavior）
(C)內隱逃避（covert avoidance）與安全型行為（safety behavior）

Key points
1. Two definite transdiagnostic processes have been identified: overt avoidance and safety behaviour.
2. One possible transdiagnostic process has been identified: ineffective safetysignals.

例子：
overt avoidance：避免出門、購物(for SAD)
safety behaviour：在社交場合緊握玻璃杯(for SAD)、戴頭盔(for 有被害妄想的psychosis)
ineffective safetysignals：重複檢查瓦斯爐是否關(for OCD)
