Periodic Reporting for period 1 - MENTAL IMAGERY (The power of imagination – Breaking through behavioural avoidance in depression with mental imagery)
Berichtszeitraum: 2016-04-01 bis 2018-03-31
Depression causes significant suffering for the person who is affected but also for those around them and the society at large. The costs associated with depression are substantial due to direct costs of the disorder (i.e. costs of treatment) as well as indirect costs (e.g. work absence). Developing innovative and accessible interventions for depression has the potential to have a significant impact on the well-being of patients and their significant others (societal impact) which can ultimately contribute to significant reductions in health care costs (economic impact).
The overall objective of this project was to develop and test innovative procedures that might have the potential to help individuals with depression to engage in enjoyable activities. Individuals with depression are often stuck in cycles of low mood, negative thinking and avoidance of activities. One goal of many treatments for depression is to help individuals with depression engage in enjoyable activities. However, a lack of energy, low motivation and a general loss of interest in activities are typical symptoms of depression which make it difficult to achieve this goal. One potential way forward is to develop procedures that more directly promote engagement in potentially enjoyable activities. Previous research has indicated that mentally simulating engagement in a wide range of activities (e.g. exercising) through mental imagery (i.e. seeing with the mind’s eye) can boost engagement in these activities. Testing if mental imagery of engaging in potentially enjoyable activities can increase motivation and engagement in these activities has potential implications for the treatment of depression where the aim is to help patients engage in enjoyable activities.
After having presented initial evidence that mental imagery of positive activities leads to increased behavioural activation in individuals with depression the next question was whether and under which conditions a specific behavioural activity can be promoted by positive mental imagery. We have started to explore this question during the fellowship. In an experimental study conducted under the fellowship, individuals with varying levels of depressive symptoms have selected and planned in six activities to engage in over the following week. Participants in a mental imagery condition simulated engagement in the selected activities and the associated positive emotional experiences. The study is currently under consideration for publication and results are promising in demonstrating positive effects of the mental imagery condition compared to control groups.
