Research summary
People with advanced dementia often lose the ability to communicate using speech. Research suggests that these individuals retain the desire to connect with others (Ellis and Zeedyk, 2014). Reduced ability to do so is known to create frustration (Stokes, 2000). Adaptive Interaction is a non-verbal communication technique which enables caregivers to interact with people with advanced dementia in a way that is meaningful to both parties. It involves mirroring the sounds and gestures of the individual with advanced dementia (Ellis and Astell, 2011). Behavioural research has shown that Adaptive Interaction can engage people with advanced dementia in social interactions and increase the amount and the range of their social behaviours (Ellis and Astell, 2008).
The aim of this project is to measure hormone levels to determine a link between Adaptive Interaction and physiological markers that could show reduced stress responses and increased feelings of connectedness. Cortisol and oxytocin levels will be measured as cortisol is the main stress hormone in humans (McEwen, 1998) and oxytocin is important in mediating social communication and interaction (Gimpl & Fahrenholz, 2001).
Participants will receive 20 minutes of one of the following 'interactions': Adaptive Interaction, closed questioning (caregivers often communicate with people with advanced dementia in this way), sitting with the person without communication or leaving the person alone (as they would often be in the home setting). Saliva samples will be taken at three different times to measure levels of cortisol and oxytocin: before the interaction (baseline); after the condition to test for immediate effects and four hours later to test for prolonged effects.
If Adaptive Interaction reduces stress and facilitates social communication or recognition then we predict that we will find reduced cortisol and increased levels of oxytocin in patients undergoing the Adaptive Interaction condition compared to the other conditions.
