The 'Mean Girls' actress has been advised by doctors at Cliffside treatment facility in Malibu, California, to have three 50-minute sessions a week with a psychiatrist for the next 16 months to avoid a serious relapse into alcohol and drug abuse.
The 27-year-old star left rehab on Tuesday following a 90-day court-ordered stint, and medical staff are worried her resolutions won't hold in the outside world.
In a letter to the judge, Cliffside explained that while Lindsay has "successfully completed her court-ordered course of treatment at the center", they believe therapy is "critical" to her recovery.
According to People.com, it reads: "Our entire clinical team is in unanimous agreement that if these sessions are not required by the court and attendance verified once a month to ensure accountability, it is a set up for almost certain failure."
Richard Taite, Cliffside Malibu's founder and CEO, added that the therapy "should be done face to face while she is in town, and via Skype or phone session if she is out of town."
Lindsay's lawyer Shawn Holley announced she is determined to stay out of trouble and will stay with a sober coach in Los Angeles for the next few days.
She told E! News: "It was [Lindsay's] idea to have a sober coach with her. She is doing well. She is so positive and [wants to get] her life on the right track."
