Computer-based treatment for adolescent anxiety shows promising results
For adolescents diagnosed with an anxiety disorder, a simple computer-based program known as attention training may offer relief, according to a new Yale-led study.
In a promising finding, researchers discovered major reductions in anxiety among 64 youths after just four twice-weekly sessions of the attention training program. All the youths had diagnosed anxiety disorders and had completed cognitive behavior therapy (CBT) — the standard treatment for adolescent anxiety — without improvement. After attention training, half the participants no longer met the criteria for an anxiety diagnosis, and the benefits remained at the two-month follow-up.
Although experts consider CBT the strongest evidence-based treatment for children and adolescents with anxiety disorders, up to 50% of youth with anxiety disorders do not respond to CBT.
“The fact that we could show in a hard-to-treat sample that half of participants did respond suggests that attention training is working through a different mechanism than CBT that is beneficial to these children,” said Yale’s Wendy Silverman, the Alfred A. Messer Professor of Child Psychiatry and director of the Anxiety and Mood Disorders Program at the Yale Child Study Center.
The researchers are currently enrolling participants (ages 10-14 years) for a much larger two-site treatment study at Yale and Florida International University. Researchers hope to confirm the efficacy of attention training, and to better understand the underlying mechanisms.
In the attention training program, participants sit alone in a room with a computer. Two faces flash on the screen: one threatening, one non-threatening. Milliseconds later, another pair of faces appear. And another. Participants are instructed to click on the arrow that always points to the non-threatening face. The images change so rapidly that participants are not consciously aware as they click of the varying facial expressions. But as they click, their brains are being trained to turn away from the threatening stimuli to which they have become hyper-attuned.
“People with anxiety problems — their attention goes immediately to threatening stimuli,” Silverman said. “We are training the brain to look away from the threat.”
Shantia Rooplal’s 12-year-old daughter, Krysila, began exhibiting anxious behaviors in second grade — obsessively biting her nails and responding negatively to teachers and social situations. It was years, Shantia said, before she understood that something was wrong.
“I saw the same pattern in classroom after classroom,” she said. “Lots of social issues, especially at school. Always negative things about the playground, the teachers.”
Rooplal said her daughter would regularly come home from school upset and out of control, yelling and screaming in full-blown tantrums.
Following an assessment for anxiety at the Yale Child Study Center, Krysila completed the four-week attention training. Her mother said the difference was remarkable.
“Before, she would be just really, really angry and upset in a disturbing way. After the treatment, I never see that behavior,” she said.
There are real advantages to using a computer-based program for kids with anxiety, particularly social anxiety, Silverman said.
In CBT sessions, adolescents have to do a number of tasks they find challenging — talking to people, ordering food, making phone calls — in addition to long talks with a therapist.
“Children, adolescents, and adults with social anxiety are easily embarrassed and concerned about what other people think,” she said. “Engaging them in verbal forms of therapy can often be very difficult. And studies show that youth with social anxiety respond less well to CBT compared to those with other anxiety disorders.
Researchers hope attention training can serve as a new, efficient tool for helping these kids manage their hard-to-treat anxiety with limited discomfort.
What’s more, said Silverman, the treatment could easily be used in “step care,” preventing early signs of anxiety from becoming a more full-fledged disorder.
Adolescents ages 10-14 with social anxiety may be eligible for participation in the study. For further information, call the Yale Child Study Center’s Anxiety and Mood Disorders Program at 203-737-4644.
