This evidence theme on psychological interventions is a summary of one of the key topics identified by a scoping review of dementia research. If you need more information on this topic, try using the PubMed search below.
We found five systematic reviews that assessed the impact of psychological interventions for people living with dementia and/or their carers. These studies aimed to find out if psychological interventions reduced outcomes such as depression and anxiety, or improved outcomes such as quality of life, for both those living with dementia and those providing care.
Overall, some studies report the benefits of psychological interventions for persons living with dementia. For validation therapy, these include reductions in responsive behaviours and carer distress. [3]
For cognitive behaviour therapy, there was some evidence of benefit for people living with dementia. Benefits included improvements in:
- Depression [3]
- Quality of life. [3]
However, there was only limited improvement in self-esteem and cognitive functioning, and no change in people’s ability to manage their self-care. [3]
For person-centred counselling, there was evidence of improvement in cognition and mood for the person living with dementia, as well as carer attitudes. [3] There is inconclusive evidence that person-centred counselling improves depression. This is because some studies observed benefits while others did not. [3]
For group psychotherapy, there was evidence from one study for improvement in quality of life for the person living with dementia, and carer coping. [3]
There is inconclusive evidence that group psychotherapy reduces depressive symptoms for the person living with dementia. This is because some studies reported benefits while others did not. [3]
The evidence for functional analysis for managing responsive behaviours remains inconclusive but promising according to one review. [5]
A review that focused on psychological treatments, in general, reported an overall positive impact on depression. [2] There is inconclusive evidence that psychological treatments influence:
- Neuropsychiatric symptoms [2]
- Cognition [2]
- People’s ability to manage their self-care [2]
- Anxiety [2, 3]
- Carer self-rated depressive symptoms. [2]
This is because some studies reported that psychological treatment influenced these outcomes, and others did not.
Studies that have assessed the relationship between psychological interventions overall and quality of life for the person living with dementia found no benefit. [2] In our search, we did not find any reviews that focused on mindfulness.
Overall, psychological interventions are most effective when:
- They have multiple components [7]
- They incorporate technology [7]
- They combine individual and group sessions [7]
- They are personalised to the individual [7]
- Group interventions are focused on a common issue. [7]
