Experimental Group: Women looking after a relative with alzheimers (they wanted to see if psychological stressors can cause damage to the immune system)
Control Group: Women matched in age and family income to the carers
- The carers scored highest on the perceived stress scale
- Then, a small wound was created in the arms of all participants
- They measure the healing by photographing the wound reglary and observing the response to hydrogen peroxide - absence of foaming indicated healing
- The caregiver's wounds took the longest to heal: 48.7 days
EVALUATIONS
- Natural study
- Ethical issue: Protection from harm - small wounds involve pain so full informed consent and approval from ethics committee is required
