These conclusions are based a number of recent studies which were reviewed in the article and presented at the Science Festival. These included:
- A 2008 study (published in Neuropsychological Rehabilitation) of stroke sufferers. This showed that being able to maintain valued group memberships played as important a role in positive recovery as an ability to overcome cognitive difficulties (e.g., problems with memory and language). After their stroke, people's life satisfaction increased by 12% for every group membership that they were able to retain.
- A 2009 study (in press at Ageing and Society) of residents entering a new care home. This showed that those who participated as a group in decisions related to the decoration of communal areas used those areas 57% more over the next month and were far happier as a result. In contrast, the use of space by residents in a control group declined by 60%. Moreover, these differences were still apparent three months later.
- Another 2009 study (under review at Psychology and Aging) looked at the impact of group interventions on the health and well-being of 73 people residing in care. After a period of six weeks the researchers found that people who took part in a reminiscence group showed a 12% increase in their memory performance, while those who received individual reminiscence or a control intervention showed no change.
- Another 2009 study (in press at the Journal of Clinical and Experimental Neuropsychology) also studied nursing home residents and looked at the relationship between their sense of identity and well-being and the severity of their dementia. The study's key finding was that a strong sense of identity associated with perceived membership of social groups, was a much better predictor of residents' well-being than their level of dementia.
