Study Questions Effectiveness of Therapy for Suicidal Teenagers

Most adolescents who plan or attempt suicide have already received at least some mental health treatment, raising questions about the effectiveness of current approaches to helping troubled youths, according to the largest in-depth analysis to date of suicidal behaviors in American teenagers.

[Matt Nock, a professor of psychology at Harvard and the lead author of a study on the mental health treatment of troubled young people, said his research showed that “we’ve got a long way to go to do this right.” The study found that 55 percent of adolescents who plan or attempt suicide have already received some therapy.]

The study, in the journal JAMA Psychiatry, found that 55 percent of suicidal teenagers had received some therapy before they thought about suicide, planned it or tried to kill themselves, contradicting the widely held belief that suicide is due in part to a lack of access to treatment.

The findings, based on interviews with a nationwide sample of more than 6,000 teenagers and at least one parent of each, linked suicidal behavior to complex combinations of mood disorders like depression and behavior problems like attention-deficit and eating disorders, as well as alcohol and drug abuse.

The study found that about one in eight teenagers had persistent suicidal thoughts at some point, and that about a third of those who had suicidal thoughts had made an attempt, usually within a year of having the idea.

Previous studies have had similar findings, based on smaller, regional samples. But the new study is the first to suggest, in a large nationwide sample, that access to treatment does not make a big difference.

The study suggests that effective treatment for severely suicidal teenagers must address not just mood disorders, but also behavior problems that can lead to impulsive acts, experts said. According to the Centers for Disease Control and Prevention, 1,386 people between the ages of 13 and 18 committed suicide in 2010, the latest year for which numbers are available.

“I think one of the take-aways here is that treatment for depression may be necessary but not sufficient to prevent kids from attempting suicide,” said Dr. David Brent, a professor of psychiatry at the University of Pittsburgh, who was not involved in the study. “We simply do not have empirically validated treatments for recurrent suicidal behavior.”

The report said nothing about whether the therapies given were state of the art or carefully done, said Matt Nock, a professor of psychology at Harvard and the lead author, and it is possible that some of the treatments prevented suicide attempts. “But it’s telling us we’ve got a long way to go to do this right,” Dr. Nock said. His co-authors included Ronald C. Kessler of Harvard and researchers from Boston University and Children’s Hospital Boston.

Margaret McConnell, a consultant in Alexandria, Va., said her daughter Alice, who killed herself in 2006 at the age of 17, was getting treatment at the time. “I think there might have been some carelessness in the way the treatment was done,” Ms. McConnell said, “and I was trusting a 17-year-old to manage her own medication. We found out after we lost her that she wasn’t taking it regularly.”

In the study, researchers surveyed 6,483 adolescents from the ages of 13 to 18 and found that 9 percent of male teenagers and 15 percent of female teenagers experienced some stretch of having persistent suicidal thoughts. Among girls, 5 percent made suicide plans and 6 percent made at least one attempt (some were unplanned).

Among boys, 3 percent made plans and 2 percent carried out attempts, which tended to be more lethal than girls’ attempts.

(Suicidal thinking or behavior was virtually unheard-of before age 10.)

Over all, about one-third of teenagers with persistent suicidal thoughts went on to make an attempt to take their own lives.

Almost all of the suicidal adolescents in the study qualified for some psychiatric diagnosis, whether depression, phobias or generalized anxiety disorder. Those with an added behavior problem — attention-deficit disorder, substance abuse, explosive anger — were more likely to act on thoughts of self-harm, the study found.

Doctors have tested a range of therapies to prevent or reduce recurrent suicidal behaviors, with mixed success. Medications can ease depression, but in some cases they can increase suicidal thinking. Talk therapy can contain some behavior problems, but not all.

One approach, called dialectical behavior therapy, has proved effective in reducing hospitalizations and suicide attempts in, among others, people with borderline personality disorder, who are highly prone to self-harm.

But suicidal teenagers who have a mixture of mood and behavior issues are difficult to reach. In one 2011 study, researchers at George Mason University reduced suicide attempts, hospitalizations, drinking and drug use among suicidal adolescent substance abusers. The study found that a combination of intensive treatments — talk therapy for mood problems, family-based therapy for behavior issues and patient-led reduction in drug use — was more effective than regular therapies.

“But that’s just one study, and it’s small,” said Dr. Brent of the University of Pittsburgh. “We can treat components of the overall problem, but that’s about all.”

Ms. McConnell said that her daughter’s depression had seemed mild and that there was no warning that she would take her life. “I think therapy does help a lot of people, if it’s handled right,” she said.

Patients who use anti-depressants are more likely to suffer relapse, researcher finds

Science Daily
July 19, 2011

Patients who use anti-depressants are much more likely to suffer relapses of major depression than those who use no medication at all, concludes a McMaster researcher.

In a paper that is likely to ignite new controversy in the hotly debated field of depression and medication, evolutionary psychologist Paul Andrews concludes that patients who have used anti-depressant medications can be nearly twice as susceptible to future episodes of major depression.

Andrews, an assistant professor in the Department of Psychology, Neuroscience & Behaviour, is the lead author of a new paper in the journal Frontiers of Psychology.

The meta-analysis suggests that people who have not been taking any medication are at a 25 per cent risk of relapse, compared to 42 per cent or higher for those who have taken and gone off an anti-depressant.

Andrews and his colleagues studied dozens of previously published studies to compare outcomes for patients who used anti-depressants compared to those who used placebos.

They analyzed research on subjects who started on medications and were switched to placebos, subjects who were administered placebos throughout their treatment, and subjects who continued to take medication throughout their course of treatment.

Andrews says anti-depressants interfere with the brain's natural self-regulation of serotonin and other neurotransmitters, and that the brain can overcorrect once medication is suspended, triggering new depression.

Though there are several forms of anti-depressants, all of them disturb the brain's natural regulatory mechanisms, which he compares to putting a weight on a spring. The brain, like the spring, pushes back against the weight. Going off antidepressant drugs is like removing the weight from the spring, leaving the person at increased risk of depression when the brain, like the compressed spring, shoots out before retracting to its resting state.

"We found that the more these drugs affect serotonin and other neurotransmitters in your brain -- and that's what they're supposed to do -- the greater your risk of relapse once you stop taking them," Andrews says. "All these drugs do reduce symptoms, probably to some degree, in the short-term. The trick is what happens in the long term. Our results suggest that when you try to go off the drugs, depression will bounce back. This can leave people stuck in a cycle where they need to keep taking anti-depressants to prevent a return of symptoms."

Andrews believes depression may actually be a natural and beneficial -- though painful -- state in which the brain is working to cope with stress.

"There's a lot of debate about whether or not depression is truly a disorder, as most clinicians and the majority of the psychiatric establishment believe, or whether it's an evolved adaptation that does something useful," he says.

Longitudinal studies cited in the paper show that more than 40 per cent of the population may experience major depression at some point in their lives.

Most depressive episodes are triggered by traumatic events such as the death of a loved one, the end of a relationship or the loss of a job. Andrews says the brain may blunt other functions such as appetite, sex drive, sleep and social connectivity, to focus its effort on coping with the traumatic event.

Just as the body uses fever to fight infection, he believes the brain may also be using depression to fight unusual stress.

Not every case is the same, and severe cases can reach the point where they are clearly not beneficial, he emphasizes.
