In the context of social work, which of the following is a guideline for employing confrontation effectively?​

A) ​Use confrontation when clients are experiencing extreme emotional strain.
B) ​Use confrontation as often as possible.
C) ​Expect immediate change after confrontation.
D) ​Encourage self-confrontation whenever possible.

Encouraging self-confrontation whenever possible is a guideline for employing confrontation effectively in social work. This approach empowers clients to examine their behavior and motivations, leading to lasting change. Using confrontation when clients are experiencing extreme emotional strain may not be helpful, as it can increase stress and resistance. Using confrontation as often as possible can cause clients to become defensive and resistant to change. Expecting immediate change after confrontation is unrealistic and can undermine the trust between the client and social worker.
