Which basic principle of Alcoholics Anonymous (AA) should a client with alcohol use disorder follow?

The correct answer is that amends must be made to each person who has been harmed. This principle is reflected in the eighth step of the 12 steps of AA, which involves making a list of all persons harmed and being willing to make amends to them. It is a fundamental principle of AA to address past harms and seek to rectify them. Choice A is incorrect because spouses attending Al-Anon meetings is not a basic principle of AA; it is a support group for family members of individuals with alcohol use disorder. Choice B is incorrect because while focusing on long-term goals can be beneficial, AA emphasizes taking one day at a time rather than committing to long-term goals. Choice D is incorrect because AA teaches that individuals struggling with alcoholism are powerless over their addiction and need to rely on a higher power rather than solely their willpower to overcome it.
