The project is a cooperation between the University of Heidelberg, the German Cancer Research Center, the University Hospital Heidelberg and the National Center of Tumor Diseases.

Funding: Deutsche Krebshilfe
Term: 01.03.2015 – 28.02.2018


Principal Investigators: Prof. Dr. Monika Sieverding, Prof. Dr. Karen Steindorf, Dr. Joachim Wiskemann

Brief description

Dealing with a cancer disease varies substantially between affected persons. A lot of cancer patients perceive it as helpful to use additional actions and strategies besides the medical treatment. Within the Momentum Project, we investigate which strategies are used and also recommended for a better coping with the disease. This can relate to nutritional strategies, physical activity, psychological support, self-help groups or natural medicine. We are interested in the point of view and experience of affected persons, physicians and nurses.

Main goal of the survey is to find out more about the attitude of affected persons towards different additional actions and strategies and which ones they are using themselves. In addition, we are interested if and to what extent these strategies are part of the consultations with their physicians or nurses.

From physicians and nurses we want to know which additional actions and strategies they believe are helpful and which recommendations they are providing. 

Furthermore, different factors are analyzed that affect the use and the promotion of additional actions and strategies, such as patient characteristics, side effects of the therapy or structural factors.

The project comprises surveys with HCP (specialized practitioners and general practitioners, N=600, oncology nurses, N=300) and cancer patients (N=1200, 400 patients each with breast, prostate or colorectal cancer) with a cross-sectional research design. Additionally, a follow-up-study with a sub-sample of cancer patients (N=180), who are at the beginning of primary or palliative cancer therapy, will be conducted with measurement points immediately before or shorty after treatment initiation (t0, baseline), during treatment (t1, after 4 week), and 3 months after the initiation of treatment (t2).

Order of study

For cross-sectional study participants, participation includes a one-time completion of a questionnaire. For cancer patients, it involves questions concerning different behavioral measures. Physicians and nurses are asked which recommendations they are providing towards cancer patients during therapy. Both groups are additionally surveyed regarding their attitudes and other social-cognitive variables. Important sociodemographic and medical variables are controlled. In the sub-sample of patients in the follow-up-study, objective behavioral outcomes are gathered with an accelerometer.

Current status

Our survey among physicians and nurses is completed and includes 552 physicians and 404 oncology nurses.

With regard to both surveys we have already outnumbered our study aim. 1413 patients took part in the cross-sectional survey.

In addition, 134 couples of physicians and their treating patients were gathered, offering us the possibility to match their data.

For our longitudinal study among cancer patients, we recruited 138 participants. The first scientific papers have been written by our project members: four of them have already been published in scientific journals; two more have been submitted and are currently being reviewed.
