Stress of conscience seriously influence the quality of care and the wellbeing of the care providers in care for older people. It is therefore of great importance to take measures to address, and relieve but preferably prevent stress related to troubled conscience. In our participatory action research studies, we have used troubled conscience as a driving force to relieve care providers’ burden and to increase quality of care. The aim with this paper is to present our experiences of using a further developed participatory action research process in practice to deal with care providers' troubled conscience in residential care for older people. The contribution to participatory action research practice in our studies is a support to the participatory action research process through using a modified model of problem processing, an approach which we found fruitful. In the paper, we describe our experiences and discuss them in relation to relevant literature and theory. Our experiences are that in participatory action research it is crucial to build a trusting relationship and striving to create a fruitful dialogue between the researchers and the participants. In our studies, we found that participatory action research is an easy approach to adapt as a problem-solving process in clinical practice and in nursing research.
