One of the most popular posts I’ve written on this blog concerns ‘faking’ or ‘malingering’. I’m curious about this, because even though I have been asked many times whether I have had patients that are ‘faking’, I don’t think about it very often myself. I suppose it is a subject that is dear to the heart of anyone who is concerned about ‘motivation’ – especially where entitlements to payment or other benefits are dependent on the authenticity of the person’s claim to be unable to function.
So, time to unpack the whole topic again I think.
Last time I posted I had trouble finding relevant literature – the main problem being that in academic publications where pain is being discussed, the concept of faking has been superceded by research into areas we can work with clinically. The role of determining whether malingering or faking is not one for clinicians: it properly lives within the realm of private investigators – and even then, findings are up for challenge when a person is observed behaving in one way in one setting and another in a different setting. There are so many things that influence behaviour that it’s simplistic to decide that motivation to intentionally deceive is the primary reason.
If we start with the idea that pain itself is an experience – something we can’t share with each other, in the same way we can’t share whether we see the colour blue in the same way as each other, or the taste of banana! So you and I can’t tell just how much pain any person is in.
What we depend on is behaviour – what the person actually does behaviourally when they experience pain. And you and I know that we do different things in different places even when we experience the same pain! Take the example of stubbing your toe – in your garage you’ll probably swear loudly and jump up and down. In a very quiet church? Well, we probably won’t be able to hear your swearing and your jumping might be replaced with a wince…
In another example: if someone asked you to run 200m, you might take off at a bit of a gallop, but I’ll bet that if you knew there was a large and very angry bull coming after you, you might just move a little faster!
So we know that the social environment influences pain behaviour, and we also know that beliefs about the consequences of action also influence behaviour. We know too that what people understand about the significance of their pain is also a factor that changes behaviour. If you are unaware that the tickling feeling down your leg is actually a large and venomous spider biting you, you may well ignore it, if you think the vaguely tender lump under your armpit is cancer you’ll probably pay good attention to it and ask for a medical opinion. And your reaction to this lump might be even greater if you’ve had a history of cancer in your family.
In the compensation situation, there is no doubt that the security of receiving a weekly payment can be very helpful in the initial stages of recovery from an injury. That security can become problematic when the person is being asked to undertake the relatively risky business of returning to work – What if returning to work fails? What if my pain gets so bad that I can’t keep going? What if I let my employer down?
Some of these very realistic fears can interfere with the readiness for someone to return to work – and yes, compensation means it can easier to remain in status quo than to attempt to return to work. Does this equal malingering? Is the person faking? Or would you and I feel very much the same, and be quite hesitant to risk our health and livelihood too?
Can we as health professionals ‘tell’ whether someone is intentionally faking?
The short answer is no – humans are very poor at telling whether someone is lying. That’s why movies are so successful – even though we know the people are ‘actors’!

and the truth?
For another good article on deception – if a bit cognitive – this newly published article review the latest and greatest on the art of detecting deception. It’s just too early to apply this to pain and malingering.
