CBT has been used effectively for a variety of problems, including the following:
Voices
Sometimes people can hear someone, or a number of people, speaking or shouting, but nobody else seems to hear them. “Voices” like these can be very upsetting: they may say abusive things about the person or tell them to do unpleasant things. CBT can help them better understand why these voices are happening and what to do about them. Understanding them is important in reducing the fear and anxiety they cause. CBT also teaches people a variety of techniques which can help them to better cope with the voices and maybe even to reduce them. This can give people a better sense of control over the voices, so that they can do what they want with their life and not let the voices keep them down anymore.
Other difficult experiences
CBT can also help with experiences that cause stress and get in the way of life; for example, when people believe they are being followed or plotted against or that someone or something is interfering with their brain or body. On the surface these thoughts may seem reasonable, but it could be that the fears have gotten out of proportion or things have been taken too personally. It might be possible with CBT to look at the situation differently and get a new perspective. It may be that there is a different explanation that is less upsetting and less stressful. For example, anxiety can cause all sorts of strange feelings like numbness or tingling, pain or breathing problems, but these can sometimes be misinterpreted as electric shocks or physical attacks by an outside force.
Posttraumatic stress
People who have experienced traumatic life events like life-threatening accidents, combat, and abuse often struggle with depression, anxiety, insomnia, voices, and other difficult experiences. CBT can help a person recover from their trauma in a few ways. It can help the person to make sense of what happened to them and better understand how the experience has affected their life. It can help them to let go of unhelpful ways of thinking, like blaming themselves for something that wasn’t really their fault. And it can support them to feel the emotions they need to feel in order to heal from the trauma.
Depression and anxiety
CBT works on depression and anxiety by helping the person discover unhelpful and unbalanced ways of thinking, like thinking they are a bad person (in depression) or that terrible things are going to happen and they won’t be able to handle it (in anxiety). The therapy helps them correct their thinking so that they feel better, but also encourages them to try doing things to help their mood. For example, a person with depression might schedule daily activities that give them joy and a sense of accomplishment, and someone with anxiety might practice breathing techniques to reduce their anxiety and break large, scary tasks into small steps so they’re easier to accomplish.
