The AG has as its target group people with different forms of dementia in all phases of their illness. It develops and evaluates nursing support services for all available settings that involve, encourage, inform, educate and relieve professional or non-professional participants. The focus is on researching the entire range of psychosocial interventions that support everyday life in order to promote and maintain the quality of life of people with disabilities and to improve how they deal with challenging behaviour. These interventions are to be developed to accompany people with disabilities and, above all, their effectiveness is to be assessed.

  1. The promotion and maintenance of quality of life is understood in particular to mean the quality of life specific to dementia.
  2. Improving the handling of challenging behaviour means, depending on the aim of the intervention, preventing and reducing behaviour and its negative consequences. The negative consequences include aspects that affect the person with dementia and aspects that affect the carer.

The development and evaluation of methods are an integral part of intervention research, which includes research designs, development and testing of instruments and analytical aspects which have the potential to do justice to the subject matter of intervention research within the working group.

In the working group “care interventions”, intervention research means all phases of  development and evaluation of complex  interventions. They contain:

  1. identification, description and quantification of relevant health care problems and phenomena
  2. Identification and evaluation of evidence of existing interventions
  3. Theoretically guided development of new interventions and adaptation of nationally and internationally existing interventions
  4. Modelling and piloting of interventions
  5. Evaluation of the effectiveness of interventions
  6. Process evaluations of the implementation of interventions in the daily routine
