In one study, people with obsessive-compulsive behaviors learned to relabel their compulsive thoughts (Schwartz et al., 1996). Feeling the urge to wash their hands again, they would tell themselves, “I’m having a compulsive urge,” and attribute it to their brain’s abnormal activity, as previously viewed in their PET scans. Instead of giving in to the urge, they would then spend 15 minutes in an enjoyable, alternative behavior, such as practicing an instrument, taking a walk, or gardening. This helped “unstick” the brain by shifting attention and engaging other brain areas. For two or three months, the weekly therapy sessions continued, with relabeling and refocusing practice at home. By the study’s end, most participants’ symptoms had diminished and their PET scans revealed normalized brain activity. Many other studies confirm cognitive-behavioral therapy’s effectiveness for those suffering anxiety, depression, or anorexia nervosa (Covin et al., 2008; Mitte, 2005; Norton & Price, 2007). Studies have also found that cognitive-behavioral skills can be effectively taught and therapy conducted over the Internet (Barak et al., 2008; Kessler et al., 2009; Marks & Cavanaugh, 2009; Stross, 2011).
