A recent study says “yes”!

Online therapy is an active and growing area of research in clinical psychology. In fact, there was a symposium devoted to the subject at the recent World Congress of CBT in Lima, Peru (which I was honoured to be a part of – to be covered in a future blog). Perhaps the most important question that researchers are trying to answer is: “Does online work as well as face to face therapy?”

This is a difficult question to answer since there are so many hidden variables. In fact, there is no universal answer, since it depends on the particular online system being examined, and the skill level of the therapists involved in the study. A better questions is “Can online therapy work as well as face to face therapy?” In other words, are there any online systems that can match the results of live therapists for a specific problem? According to a recent publication, the answer is “yes”!

A team of researchers from the University of Zurich published the following paper:

Birgit Wagner, Andrea B. Horn, Andreas Maercker. Internet-based versus face-to-face cognitive-behavioral intervention for depression: A randomized controlled non-inferiority trial. Journal of Affective Disorders. July 23, 2013. (see this link for more information)

The authors conducted a study involving 62 people with moderate depression. Half of the patients were treated using traditional CBT in-person techniques, and the other half were treated online. The authors found that at a three month follow up, the patients who were treated online had fewer symptoms of depression than the control group. In other words, the online treatment program actually performed better than the face to face therapy.

Advantages of online therapy

I have discussed some of the advantages of online therapy on this blog and in my publications. These include:

Clients can progress at their own pace
Clients have a complete record of their treatment, which they can revisit at any time
“Therapist drift” is a known phenomenon, where therapists move away from the best practices of a particular treatment over time. With online treatments, it is easier to enforce a consistent treatment, with the correct “dose” of clinical content delivered during each session.

Of course, online therapies have challenges of their own. In particular, it is more difficult to adapt the treatment towards the individual symptoms and needs of the users without therapist involvement. In fact, it is this problem of individual personalization that AI-Therapy’s social anxiety program attempts to address.

More studies are needed to fully investigate the strengths and weaknesses of online therapy. However, the study above adds to a growing body of evidence that online therapy has tremendous potential, and will play an important role in the future of mental health treatment.

Earlier this year I presented the Overcome Social Anxiety treatment program to my colleagues in the Department of Psychiatry at the University of Oxford. One of the questions from the audience was: How do you diagnose social anxiety in order to treat individuals? My answer: I don’t.

In the last blog I discussed the controversy around the new DSM-5. The goal of the DSM is to define the criteria for a formal diagnosis. In other words, it helps a practitioner determine whether or not person X has condition Y. I pointed out the shortcomings of this approach. In particular, the severity of a mental disorder is best measured using a continuous scale, rather than a binary classification.

A DSM diagnosis is important in a situation where a patient may be prescribed medication (recall that the DSM is published by the American Psychiatric Association). Most drugs have negative side effects, and they carry the risk of addiction. Therefore, taking medication for mild or moderate cases may not be a good idea. In this case, the DSM plays a vital role in determining who receives treatment. The DSM also plays a crucial role for clinical psychologists, as it guides the diagnosis and treatment of patients.

The situation for online self-help is different. For example, consider our Overcome Social Anxiety program. At the start of the program each user completes a series of standardized questionnaires (e.g. the “Fear of Negative Evaluation Scale” and the “Depression, Stress and Anxiety Scale”). The goal of this assessment is not a diagnosis. Rather, the goal is to determine where the user falls on the social anxiety spectrum prior to treatment. After the user completes the treatment program, they fill out the same questionnaires. The results are compared to the user’s pre-treatment results to see if their symptoms have improved.

We don’t require a diagnosis to use the program since people from along the whole social anxiety spectrum, from mild to severe, can benefit from treatment. The program uses online cognitive behavior therapy (CBT), which is known to be helpful in a wide range of cases. CBT involves revisiting thinking styles and behaviors. Unlike drugs, there are no negative side effects of CBT. Therefore, it can help everyone make better choices in their day to day life. This typically leads to an overall improvement in happiness and confidence, regardless of a DSM diagnosis.

How are social anxiety and depression related?

Social anxiety and depression often occur together, and research has shown that targeting social anxiety can lead to an overall increase in mood and happiness. In this blog we look at an example of how the two can be connected.

A thought pattern that can be a contributing factor to depression is rumination. Let’s consider the following scenario: you’ve been to an evening party, and the first thought that pops into your head the next morning is “Oh no, did I really say that? I wish I hadn’t – I may have offended someone.” You continue to dwell on the thought, and over time your feelings of anxiety amplify. Eventually, you convince yourself that it was a terrible scene, and you become angry and upset.

Rumination following social situations is a common symptom of social anxiety. The social anxiety is leading you to (a) set unrealistic expectations for yourself, and (b) over-analyze the event after the fact. By targeting social anxiety, you will be less likely to ruminate, and therefore spend less time being self-critical.

As a side note, this is consistent with the results that we are observing with our social anxiety program. In particular, there is a (statistically significant) decrease in symptoms of low mood for those who complete the program. Dealing with social anxiety can have follow-on effects that lead to a happier, more fulfilling life.

There is a well known 2011 study that looks at the brains of London taxi drivers. The map of London is complex, and taxi drivers are required to memorize the complete layout and pass a difficult exam before being given their taxi license. The study found that the hippocampus region of the brain, which plays an important role in memory, actually grows (in a physical sense) while the prospective drivers are studying for the exam. This is an interesting result since it clearly shows that our actions can make real, measurable changes to our brains.

Can you change your brain with therapy?

In short, yes.

Some people view psychological treatments as “softer” than using medication, since drugs can directly target neurochemical aspects of the brain. However, this view is unjustified, since there is mounting evidence that therapy can make very real structural changes to the brain. A great example is CBT.

Cognitive behavior therapy (CBT) is an evidence-based approach to tackling mental health problems, such as anxiety or depression. CBT has been subject to countless clinical trials, and has even been shown to be more effective than medication in some long-term studies. CBT works by targeting the thoughts and behaviours that are maintaining the problem (more information about CBT, and how it can be administered online, can be found here). For example, consider someone who has social anxiety and would like to ask their boss for a raise or promotion. This would be extremely stressful situation for them, and they would likely put it off indefinitely. CBT treatment would examine the thoughts that are leading to this avoidance, and would challenge them through a series of exercises. In much the same way that physical exercise changes the body, these mental exercises can make changes to the structure of your brain!

How does CBT change the brain?

The fact that CBT changes the brain is not a particularly new result. However, neuroscience journals tend to announce findings with headlines like “The neurobiological role of the dorsolateral prefrontal cortex in…”. The details are complex, but the general idea is understandable in surprisingly basic terms.

The brain is divided into different regions or modules, each of which is specialized to perform a certain type of task. For example, the visual cortex is the region of the brain that processes the sensory input from the eyes. There are some brain structures that deal with emotions such as stress and fear, and collectively these are sometimes known as the “emotional brain”. These are very “old” areas of the brain, in the sense that we share them with our distant ancestors. When a socially anxious person is nervous when thinking about asking for a raise, it is the emotional brain that is becoming active.

There are higher order brain structures that deal with planning, logic and reasoning. These are sometimes known as the “logical brain”. These brain areas, such as the prefrontal cortex, are “newer” in the sense that they are much larger in primates than in other species. There are two key points:

The logical brain is able to override the emotional brain. For example, our socially anxious person can take a rational look at the situation, and realize that he or she is exaggerating the potential risks. He or she might come to the conclusion “the worst case scenario is that the boss says no – that’s not the end of the world!” This thought will help them calm down, and build the confidence to actually ask for the raise.
–
Every time the logical brain overrides the emotional brain, the logical brain “muscle” becomes stronger and stronger. In other words, through CBT training the brain actually reinforces the neural pathways, so it becomes easier and easier to deal with future stressful situations.

This is good news: by changing our thinking and behaviour using CBT, we are making positive, long term, hard coded changes to our brains!

Blushing

Question: When I blush, is my face as red as I think it is?

Answer: Probably not!

During my postgraduate training at Murdoch University in Perth, Western Australia, I was lucky to be involved with a fascinating research project related to blushing and worry about blushing. The team was led by Professor Peter Drummond, one of the leading authorities in blushing research. ABC Science in Australia published a great article about the work: Fear of blushing brings blush on itself.

For the project I was involved in [1], we looked at the actual physiological changes in people who had fear of blushing, and compared this to a control group. This involved measuring changes in blood flow in subject’s faces while they performed embarrassing or stressful tasks, such as delivering a speech and listening to it afterwards. The results demonstrated that people with a fear of blushing tended to overestimate the extent of their actual physiological change. As Professor Drummond concludes in the article above “it turned out there was very little connection between how strongly people blush and how much they thought they were blushing”. This is good news for people who are worried about blushing, as it suggests that their faces are not as red as they think.

Social Anxiety and Blushing

Professor Drummond’s more recent work examines the relationship between social anxiety and blushing. The results show that social anxiety is one of the best predictors of blushing. Therefore, as the title of the article suggests, the fear of blushing can be a self-fulfilling prophecy. This finding is valuable as it has direct practical implications for the treatment of social anxiety. In particular, it suggests that targeting the fear of blushing (e.g. through CBT) may have wider benefits.

Arguably no other notable figure in history was so fantastically wrong about nearly every important thing he had to say. – Todd Dufresne on Sigmund Freud in a 2004 LA Times Article

Freud was strange. On one hand, he’s the most famous therapist in history, and I have to admit I was excited to visit his former clinic on vacation in Vienna last year:

On the other hand, his theories are at best unsupported by evidence, sometimes completely ridiculous (I’m looking at you, penis envy), and at worst harmful.

Freud invented a form of psychological treatment called psychoanalysis. One of the cornerstones of psychoanalysis is that our personalities are strongly dependent on events in our early childhood. Obviously, this is true to some degree. We are all shaped by both our genetics and personal history, and childhood experiences can be influential. However, Freud and modern evidence-based psychology differ on how we should go about dealing with our past.

Dealing with the past is a controversial and complex topic. To begin with, there are different types of negative past events. For example, being bullied as a child is quite distinct from a difficult breakup. Therefore, the specific treatment will depend on the individual and their circumstances. I will not attempt a full literature review of this active research area, but I will make two general comments.

1. We can’t change the past, but we can change the way we think about the past.

It is important to acknowledge the negative events of our past, but unlike psychoanalysis, we must realise that they do not determine “who we are”. We are capable of living happy lives if we learn to think in a more rational, positive way. How can we accomplish this? If you’re a regular reader of my blog you will know what I’m about to say: cognitive behaviour therapy (CBT). CBT does NOT adhere to “just get over it” attitude. Rather, the goal of CBT treatment is to identify and target the unhelpful thinking patterns in the present that are maintaining the problem. Ultimately, the aim is to get to the point where these memories no longer upset us. In a sense, CBT therapy really isn’t about the past at all.

2. Dwelling too much on the past is not good for our mental health. However, if not the past, what should we be thinking about? When are we happiest?

“Live in the moment” is common advice, and in this case, it seems to be right! There is some interesting research that shows we are happiest when we are absorbed in what we’re doing, not letting our minds wander. CBT also has strategies to help people accomplish this! I try to do this as much as possible, while taking the occasional break to plan my future using my nerdy excel method.

These two points have something in common: the present. Since Freud’s time, it seems we’ve learned that living in the present is the key to dealing with the past.

Parks and Recreation by Amy Poehler (a.k.a. Leslie Knope) is a hilarious show; it has me in tears every time. I’ve been told more than once that Leslie and I share some traits in common. I take this as a compliment, as her character is a great role model. In fact, sometimes I try to look at the world as if I was viewing it through Leslie’s eyes. Why? It makes boring and mundane situations much more lively. If she can have that much fun at a city council meeting, so can I!

Seeing the world through other people’s eyes is a common technique that is sometimes used in cognitive behavioural therapy (CBT). Obviously, that’s not all there is to CBT, but it can be a very beneficial exercise. Everyone knows someone (either fictional or real) who has a quirky way of seeing the world. They often have great stories to tell, and are generally content and happy people. Can we “borrow” their way of thinking? Would it have the potential to make us happier? Yes and yes.

The CBT tip of trying to “think like someone else” might sound a little strange, but it can be very beneficial. In fact, it can improve your mood considerably. I recently spent a day trying to think like Leslie Knope, and it was great. Who says you can’t have waffles with whipped cream for breakfast and lunch!

Here is your challenge (yes, you): Pick a person (e.g. a friend or a TV character) who has a great outlook on life. This should be someone who is relaxed and generally happy. Try “borrowing” their thinking style for a day. When you find yourself in a situation that would normally make you bored, angry, anxious, shy, etc., try to think like that other person. I would love to hear how it goes. Please send me an email (fjola@ai-therapy.com), use CBT tip in the subject line of the email, and have fun!
