PTSD therapy: computerized text analysis

I liked this presentation's direction.
2 things I would do:
1) Instead of theorizing which linguistic components might predict therapy outcome, just let the system find them. Search engine technology can do much more than just spot future tense and first person, for example, analyzing the semantics to determine the subjects in the text.
2) Effect measurement is not clear. I did not read the full article, but since it is not specified I assume nothing new. I would try to measure the results online - to see a timeline interaction between writing of the texts and well being, and also measure them in indirect ways such as biofeedback and response time to stroop tasks, since self report may interact with personal writing. Even if I am wrong, self report should be crossed with implicit measures.

So cool :)

Result based psychotherapy



Soon I will post a few literature reviews that describes the state of the art in diagnosis and treatment of sexual assault related PTSD. The review aim is to examine the viability of a results oriented therapy method for the disorder. Results oriented management is a business practice that gives preference to efficacy over any specific process, no matter how deep and meaningful that process may sound. Or in other words: "why should I talk about my mother now???"


Result oriented therapy requires a well established construction of sexual assault related PTSD and its definition as an object of therapy, representative measures of therapy effect that can be applied continuously through the process of therapy, and a variety of therapeutic methods and technologies that can be applied alternately according to ongoing efficacy feedback from measured results. The underlying assumption is that clinician time is the bottleneck in the therapeutic process, and that methods and technologies that use clinician time more efficiently can increase therapy effect within therapy and in making therapy affordable to more potential patients.


So when a patients asks why talk about mom, while the current answer is "it's a process, it could help", a therapist with any measures of efficacy can answer: "it helps you".

TeleHealth protocol: treating PTSD with PE via Skype

I like this approach. I am thinking about Therapy on Demand channels,  iphone apps etc...

2 quote from the article:

method:
"when patients had difficulty beginning in vivo exercises on their own, it was helpful for the patients to complete the exercise while talking to the clinician on a cell phone."

conclusions:
"Prolonged Exposure therapy via telehealth technology was associated with large reductions in symptoms of  PTSD and depression for veterans diagnosed with combat-related PTSD. In the current sample, telehealth PE treatment was safe and pragmatically viable. Treatment noncompletion rates, although higher than average for our clinic, were in the acceptable range."

(Tuerk et al., Journal of Traumatic Stress, Vol. 23, No. 1, February 2010, pp. 116–123)

Looks like people are doing it. skype therapy I mean...

Could prolonged exposure therapy (PE) have saved Hemingway from suicide?

I explained to Ernest that the best way to get over his traumatic injury is to focus on it with full detail until the anxiety loses potency, and he gets used to the things he so far avoided. He first did not understand how this is different from his compulsion to write prose about his distress, but he was willing to try, as the seemingly brave approach seemed appropriate to him.

When first asked to rank his fears, he could not admit any fear. Later he was willing to write a list of "things he'd rather not have to face". On the bottom of the list he wrote things like sleeping with the lights off, in the middle of the list he wrote things like being trapped in a prison cell, and at the top he wrote he feared physical torture and severe injury. These things kept him anxious and awake at nights.

Explaining treatment rational took up most of the next two meetings and Ernest did not perform his homework for them. We discussed this as avoidance on his part, and agreed to move very slowly up his list of things he'd rather not face. We also agreed to start first in the therapy room, and only later at home when he was alone. 

Ernest sat in the dark without screaming after two very gradual training sessions. After three sessions I even left the room for a few minutes and found him dozing in the dark, as he was exhausted with lack of sleep. At home, he changed his working schedule from writing before dawn to writing in the late morning, and he began to catch some sleep in the dawn hours.

Therapy continued, and Ernest's most major in vivo was swimming in the deep sea, where he used to fear he would be torn to shreds by sharks. He said that being in the water cooled him even better than a Mojito. He could sleep, he was much less edgy, being more calm allowed him to function sexually and enjoy his wife's support and warmth. After 6 months follow-up he was bellow clinical level for PTSD, however, changing his working schedule to daytime made him more distracted and he did not publish additional prose.

Another disturbing image - Hemingway drinking while ready to shoot sharks:




Could cognitive processing therapy (CPT) have saved Hemingway from suicide?

Ernest is a 62 years old novel writer, suffering from PTSD (ante literam) and depression. He was wounded in his leg 40 years ago in WWI, during a bombardment of a medical evacuation point, and ever since he has suffered from many PTSD symptoms such as: insomnia and nightmares, obsessive preoccupations with death and suicide, vivid multi-sensory flashbacks, alcohol dependency, feelings of guilt and shame, and intimacy problems revolving around difficulty to trust his lovers. He came to my clinic depressed, saying that he was diagnosed with an acute liver disease caused by alcohol abuse, and that now being without alcohol, he could not escape the intensity of his war flashbacks. Although he did not believe in psychology, he felt he was unable to bare his intruding thoughts of death and suicide and came to ask for treatment.

Therapy strategy was mainly to get Ernest to talk and write about his emotions directly – stop emotional avoidance, and to move from third person fictional writing to personal writing – accept that the event occurred as it had occurred and that no alternative fictional scenarios can replace it. Ernest being a writer, he had very firm professional positions regarding these issues, and had difficulty to comply. His main subject of writing is his distress, but he only rarely writes about the traumatic event itself, and seldom writes about his emotions in intense situations. His position was that his writing should be clean of emotional import, and that laconic and concrete messages would better explain his experience than pathetic elaborations of what he felt.

On our first session I had to convince him that even though he has been writing about the subject on and on for 40 years, he has not yet processed his experience fully. What grabbed him was the explanation about synthesized emotions compared to natural emotions. He felt he had been synthesizing emotions, and that the natural ability to feel has left him, he was either numb or distressed. He wanted to continue therapy and investigate this issue.

In his first homework he wrote about the effects of his trauma. Everything he was, was described as a result from his trauma – his problematic relationships, his risk taking behaviors, his sexual difficulties. Reviewing his essay, he did not allow me to perform a therapeutic split between his healthy side and injured side.

To his second session he came after reading about blockage points, and said he acknowledges something about this. He feels that his injury wasn’t a real battle injury, that he was awarded a fake medal, he was making coffee in a shed, a kilometer behind the front when a stray shell landed near – he was no hero, so he was not really injured. He cried, and said he was pathetic. I felt this was too intense, too soon for him, so after he calmed down, I asked him only if this direction is good for him, he agreed, and we continued.

We worked on recognizing emotions. He could not mention a situation that brought up an emotion in him. We went over the cognitive model of emotions being based on interpretations of the world. He said the world was basically very hostile, and that emotions are pains he tries to burry deep inside. After elaboration, he accepted that burying deep inside, is fear.
Therapy continued, and Ernest also rephrased his intimacy issues as trust issues, and his trust issues as fear of abandonment, based on his feelings that he was "not man enough". After 12 sessions, Ernest could recognize the blocking effect of the trauma on his cognitions, and the way they jammed his emotions in a state of fear. He recognized that feeling like a fake hero lead him to feel pathetic, unmanly and undeserving of emotions, that his third person characters were made up to deserve more than he did. He got a chance to cry during therapy, and noted how this was much better than drinking, really. His PTSD symptoms inventory was bellow clinical level after 5 months follow-up, but his laconic realism was badly damaged and he could not write prose again.

Prozac?


I'm reading this book by Dr. Derbi and Prof. Resick about treating PTSD with Cognitive Processing Therapy (CPT). As a side note, the writers say that taking anti-depressants during therapy is ok, but with a notice that it may prevent success from being attributed correctly to the efforts of the patient. 

In my view, isolating variables is a sceintific practice, and not the way to happiness. If you're depressed and you do 10 things to treat yourself: prozac, psychotherapy, chocolate, yoga, walks in the park etc., and then you're not depressed anymore, you did a good job.

It is inefficient to do 10 things without isolating the one that works, but if we go there, psychotherapy probably won't come out as efficiency queen either. 

In the search for well-being, I think a blitzkrieg model more fitting. Do 20 things that you think will make you feel better, 50% of them will work, and you have no reason to ask which. Well-being based on one practice is very fragile. 

I could write more but a picture of Dumbo seems more to the point, meaning that placebos and coincidental pseudo-factors of well-being are welcomed.
