Dr Aaron Frost looks at the psychological impact that media exposure may have on the Lindt Cafe siege survivors.


Usually I take reality TV with a grain of salt; just because I am not interested in seeing adults get drunk and compete in egg and spoon races it doesn’t mean there isn’t a market for it, and that some people find great pleasure in watching.


I feel the same about that other branch of reality TV, current affairs shows.  They tend to evoke the same response in me: “The killer lurking in your kitchen that every parent must know about” doesn’t interest me, and I generally assume that if there is something genuinely dangerous I need to know about, someone with actual qualifications will tell me about it. I try not to take my parenting advice from journalists, especially those who have risen to the heady heights of chasing down shonky plumbers required to be part of A Current Affair.


However last night I saw an advert for this week’s coming episode of 60 Minutes and was so angry that my usual indifference to these shenanigans wouldn’t cut it.


For those of you who haven’t seen the advert, Liz Hayes of 60 Minutes has gathered together the survivors of the Lindt Café siege for an interview.


While I recognize there is a legitimate public interest in sharing the stories of these people, where is the concern for their psychological welfare? Let me state this once and categorically;


Group interviews of trauma survivors increase the likelihood of developing Post Traumatic Stress Disorder (PTSD).


In the 1980’s and 1990’s it became very fashionable in psychological circles to offer “Critical Incident Stress Debriefing" (CISD). Lot of counselors and mental health professionals made a living going from one disaster to the next and providing debriefing services. The idea was that by talking about the trauma straight afterwards, you reduce the risk of developing PTSD.


Great idea, but it doesn’t work. Actually, the latest research suggests that CISD actually increases the risk of people developing PTSD. Seeing a mental health professional for debriefing after a trauma makes you more likely to develop PTSD.


There are two main reasons for this. The first is that one of the most powerful human defense mechanisms is forgetting. Most of us remember what we had for breakfast today, most of us don’t remember what we had for breakfast this day last year. We forget things. Trauma is the same, we might never forget the trauma itself, but over time there is a natural process for most people whereby the trauma becomes less raw and gradually becomes just another memory.


Most people who are exposed to severe trauma do not develop PTSD. Blindly stumbling in and getting people to recount the horror when actually they should be learning to forget about it is harmful.


The second reasons why debriefing is harmful is the bit that made me so angry when watching the 60 Minutes interview; they interviewed them as a group and exposed people to things they didn’t already know.


When something as complex as a siege happens, no one has a full perspective of the events. Some things are hidden by the fact that we were forced to face the ground, other things are hidden because we were overwhelmed by emotion and not processing things, while other things are just hidden in the mêlée.


The single biggest predictor of who develops PTSD and who does not, is when a person realizes they are going to die. People who think they are living their last seconds or minutes are at a far higher likelihood of developing trauma. Similarly, people who realise after the event that they could have died are more likely to develop delayed trauma.


When you have processed an event and dealt with it, and then suddenly someone presents a new fact that means you were much more likely to have died, the incidence of PTSD increase dramatically.


This is exactly what Hayes appears to be doing in her interview. She is deliberately asking siege survivors to fill each other in on the details they did not know.


If you are exposed to a severe trauma, there are things that a skilled mental health professional can do to help you, if you have PTSD, you can absolutely benefit from treatment. But the package of interventions available is highly nuanced and depending on individual circumstances. A skilled clinician will have read the 200 page Guidelines for Treatment of PTSD developed by the experts from the Australian Centre for Post Traumatic Mental Health, and they will know how to help.


I am assuming Liz Hayes is not a trained mental health clinician, and I assume she did not read the latest research on how best to help people with PTSD. I don’t mind that she is not helping, I mind that she is likely to harm them.


Under normal circumstances we can assume that approximately 3 of the people from the Lindt Café will develop PTSD. Thanks to this interview, it is likely that an additional survivor will also develop PTSD. To that person, when you sue Channel 9 for damages, please feel free to contact me to put your legal team in touch with the latest research to help your case.  I also hope you get awarded a payout that far exceeds the additional advertising revenue received by Channel 9 associated with the increased ratings this story will surely garner.
