There is still little knowledge about how smartphone apps can improve the quality of life in prostate cancer patients. Hence, the investigators are interested in finding out whether the simplified access to information and planning of activities increases the perceived social support in prostate cancer patients and ultimately improves their quality of life.~The duration of the study is approximately three months per participant. The WINGS smartphone application can be used from home and questionnaires can be completed online. Participants are therefore not required to be present at the University Hospital Basel during the entire course of the present study.~The investigators plan to recruit a total of 30 prostate cancer patients at the University Hospital Basel and 0-10 supporters (family members and friends) per prostate cancer patient. All study participants will have access to the regular treatment services of the University Hospital Basel.
The goal of this pilot study is to assess the perceived usability of a smartphone application called WINGS targeting psychosocial distress and well-being in prostate cancer patients and their social network. The main questions it aims to answer are:~How do prostate cancer patients and their social network rate the usability of the technology-based social-support intervention program smartphone application?~Do symptoms of prostate cancer patients improve after using the WINGS smartphone application?~Does the burden of prostate cancer patients social network decrease after using the WINGS smartphone application? Participants will be asked to use the WINGS smartphone application over the period of eight to twelve weeks and fill in questionnaires before, during, and after this time.
