6 根據緩衝假設（buffering hypothesis），社會支持的保護效果發生在下列何種情形？
(A)低壓力情境
(B)中壓力情境
(C)高壓力情境
(D)與壓力無關

Cohen 與 Will（1985）曾指出社會支持影響心理健康的兩項作用在於： 

1.「直接效果假說」（direct effects hypothesis）：透過接納、服務和情緒支持，且藉由個人需求（如：安全感、自尊、歸屬感、情感及社會肯定等）的滿足，感受到充分之支持及有自我價值感，而直接提升個人的身心健康及幸福感，並減輕壓力對個人所造成的負面影響。
2.「緩衝假說」（buffering hypothesis）：對於身處壓力情境的個人，經由社會支持的獲得，以減緩壓力對個人所造成的衝擊，間接對個人的身心健康及生活產生正面的效果。

The buffering hypothesis suggests that under some conditions social support protects (or “buffers”) individuals from the harmful effects of stressful situations. Two important conditions must be satisfied to demonstrate the buffering effect:

(1) individuals must experience relatively high levels of stress in response to a stressful situation

(2) social support is defined in terms of the availability of interpersonal resources that can potentially offset needs occasioned by the stressful event.
