Care, the Section of Physiotherapy Science. I would like to thank Helse Førde, Indre Sogn District of psychiatric centre and the municipality of Sogndal, for granting me a leave of absence. The Norwegian Fund for Postgraduate training in Physiotherapy supported the study financially. I appreciate their engagement in and attention to my work. Dr. Philos. Målfrid Råheim was my supervisor and co-author during the whole project. I am grateful for her valuable contributions to all parts of the research process. She showed me endless patience and encouragement. Dr. Med. Sissel Steihaug was also my supervisor, and co-author. Her clinical knowledge, as well as her previous research experience that included the management of large amounts of data, was of great help. She guided me to stay on the main track, not drown in details, and to try to complete in due time. Dr. Philos. Synnøve Iversen, my supervisor and co-author, inspired me to start this work. During challenging periods she helped me to see new possibilities by discussing and making sketches from a meta-perspective. Dr. Med. Per Stensland, also one of my co-authors, guided me through the first steps of the writing-process. I want to thank my colleagues at the Section of Physiotherapy Science, and the head of the section, Professor Anne Elisabeth Ljunggren, for taking good care of me and for always including me, although I part of the time stayed in Sogndal. Particularly, I want to thank Tove Dragesund, Anne Brit Sørsdahl, and Kjersti Thulin Wilhelmsen, the participants of the paper support group, for their helpful comments on unfinished drafts of different papers. Further, I want to express my gratitude to Ansgar Espeland iv and Kirsti Malterud for the opportunity to participate in their inspiring qualitative research group at the Section of General Practice. Further, I want to express my gratitude to Forum of qualitative research, at Centre for Child and Adolescent Mental Health. The core members of the group, Per Einar Binder, Marit Hafting, John Nessa, Per Stensland, as well as other colleagues, contributed to my understanding of qualitative research by commenting on different parts of my project and sharing ideas and advice. I also want to thank Svanhildur Gudmundsdottir, Oline Kolbotn, and Inger Johanne Solheim for our regular discussions and reflections about knowledge. My dear friend, Elisabeth Ravn Omdal, contributed with her language skills in paper II. Finally, I want to thank my dear family, my husband Per, my children Synne, Ane and Andreas for always believing in me and supporting me. They helped me to keep in touch with the important events of daily life. Per and Andreas read and commented the final drafts of this thesis.
