30 思覺失調症患者常出現妄想，下列那一項理論主張患者執著於其妄想的內容是為了因應或緩 解幻覺所引發的焦慮或壓力？
(A)妄想的缺損理論（deficit view of delusion）
(B)妄想的動機理論（motivational view of delusion）
(C)妄想的社會距離理論（social distant view of delusion）
(D)妄想的刻版化理論（stereotypical view of delusion）

（A）Deficit approaches,  view delusions as the consequence of defects in the normal functioning of belief mechanisms, underpinned by neuroanatomical or neurophysiological abnormalities. 
（B）Motivational approaches view delusions as extreme instances of self-deception; as defensive attempts to relieve pain and distress. 把妄想當作極端的自欺欺人的例子

另外兩個如果我查到再補充吧QQ
