Lindsay Lohan's Failed Intervention: What May Have Gone Wrong (PHOTOS)

Earlier this week, it was reported that Lindsay Lohan's father and entire management team staged an intervention for the perpetually troubled actress.

According to TMZ, Michael Lohan and several others showed up at Lindsay's house, because they believed she had fallen off the wagon and returned to her old habits. The intervention wasn't a success, as the cops arrived after someone called to report trespassers at her home.

TMZ later reported that Lindsay's father attempted to recruit "Celebrity Rehab" personality Dr. Drew Pinsky to run the intervention, but Drew declined, as he believed that his presence wouldn't help the situation. According to Michael, Pinsky believed Lindsay needed someone with a lower profile, and Michael ended up enlisting the services of an unnamed interventionist recommended by Lindsay's lawyer.

Despite the team's planning, Lindsay was not willing to listen and it may have been because not everyone was truly on board -- namely the actress's mother, Dina Lohan, who did not participate in the intervention.

According to John Southworth, a board-registered interventionist, who is often featured on A&Es "Intervention," having everyone committed to confronting an addict is crucial.

"Especially with a high profile person, if you don't have the agents, and mom, and dad, and everyone else, [it won't work] because the only reason they will go [get treatment] is because of consequences," he told The Huffington Post. "If you don't have everyone on board, it's all in vain."

Lindsay has already done five stints in rehab, but her father believes she's still abusing drugs and alcohol. In an email from Michael Lohan to Lindsay's lawyers, he claimed that he had been informed by several people that the actress was "drinking between a bottle and a bottle and a half of vodka per day" adding, "I have seen the empty bottles and even cocaine in her room at Chateau."

Lohan last checked into rehab at the Betty Ford Center in Rancho Mirage, Calif, in October 2010, but rehab is the smallest part of kicking an addiction according to Southworth, a former addict himself, who, like Lohan, went to treatment multiple times before he was able to get sober more than 20 years ago.

"Seamless, continued care for a minimum of five years," is the key to beating an addiction he said. "The problem is that people don't hang on for five years. As soon as they start looking good, and decide they don't need the [post-rehab programs] they relapse."

Lohan is far from the first public figure whose struggles with addiction have led friends and family members to step in and insist on a change. As the slideshow below shows, some of these interventions have failed -- but others have been life-saving.
