Social Anxiety – There’s An App for That?

When I first heard about studies using smartphones to treat anxiety with cognitive therapy I was intrigued, to say the least. However, I had a misconception about what that actually meant. My assumption was that the smartphone app would be automating some basic cognitive therapy, a virtual therapist that could give some reflective feedback and also give basic cognitive tools to deal with anxiety. That sounded like it might be useful, at least for mild cases, and I hoped that the app was designed to refer severe cases to an actual therapist.

I had already been very interested in the concept of online, virtual, or computer-based therapy. It seems like this is coming, but of course it needs to be researched to see how it works and for which patients.

But that is not what the smartphone app is at all. Rather it has to do with a treatment technique called cognitive bias modification (CBM). This therapy is based on research that finds that those with social anxiety have a cognitive bias which makes them attend more than others to signs of threat or to negative emotions. Further, they have a cognitive bias to interpret ambiguous social cues as hostile or negative. This raises a cause and effect question – are they anxious because they have these cognitive biases, or does the anxiety make them attend to negative emotions and interpret emotions negatively. Perhaps it is both, in a reinforcing feedback loop.

Is Kava Safe?

Kava is a plant that grows in the western Pacific. It was traditionally prepared as a drink and used for its psychoactive properties, including sedation, relaxation, and relief of anxiety. It is intoxicating but not addictive.

It has become a popular supplement in the US, used to treat anxiety, depression, insomnia, stress, and menopausal symptoms. It has also been suspected of killing quite a few people.

The AAFP Recommends Kava

In August 2007 American Family Physician, the journal of the American Academy of Family Physicians, published an article on “Herbal and Dietary Supplements for Treatment of Anxiety Disorders.”

They concluded that

St. John’s wort, valerian, and omega-3 fatty acids have little therapeutic value for anxiety disorders, and their use should be discouraged.

But they recommended kava. Not only that, they gave it the highest quality-of-evidence rating: A. They said,

Short-term use of kava is recommended for patients with mild to moderate anxiety disorders who are not using alcohol or taking other medicines metabolized by the liver, but who wish to use “natural” remedies.
