Step-by-step explanation:
When attending Alcoholics Anonymous (AA) regularly, it is difficult to determine the exact percentage of people who 'improve' since improvement can be subjective and differs for each individual. However, research suggests that attending AA meetings can be beneficial for those struggling with alcohol addiction.
According to a study published in the journal Addiction, individuals who attended AA had a 20% higher likelihood of abstinence compared to those who did not attend any such meetings. It is important to note that improvement can be measured in various ways, including maintaining abstinence, reducing alcohol consumption, or experiencing social support.
