Questions & Answers

About Untire

  • CRF is characterized by feelings of tiredness, weakness and a lack of energy related to cancer or cancer therapy. CRF impacts daily living and reduces the quality of life with social and economic consequences. Many physical problems can become intertwined with psychological factors. People become worried, desolated, stressed, pessimistic, etc. In fact, these factors can sustain the fatigue or even make it worse. Untire offers a step-by-step approach to reducing CRF and addresses all factors that may contribute to the issue.

  • The Untire App is based on many years of experience in face-to-face group therapy and online therapy with hundreds of (former) cancer patients suffering from extreme fatigue. We use theories and techniques from scientifically proven cognitive behavior therapy, mindfulness-based cognitive therapy, positive psychology and physical exercise interventions. Scientific research has shown that the results of these treatments are extremely good.

  • Untire is an easy to use step-by-step program that starts with a basic introduction to the various elements of the program. After completing the Basics, you will fill in a weekly evaluation as to how you are doing. After that, you enter a program that you can follow daily. This program consists of four main elements: stress-reduction exercises, a physical activity program, educational topics (Fatigue, Anxiety, Worry, Boundaries, Sleep, Self-Care and Nutrition) and daily tips.

    You set the pace. You can always decide in what order you want to go through the elements. You can also decide how often and how long you want to use the Untire app, because you’re the only one who can evaluate your progress.

  • Tired of Cancer B.V., founder of the Untire App, and the University of Groningen partnered together in a large study focused on cancer-related fatigue (CRF). The effectiveness of Tired of Cancer’s Untire App was studied in an international scientific study lead by Profs. Robbert Sanderman and Mariët Hagedoorn.

    At baseline, the intervention group and the control group did not statistically significantly differ with regard to demographic and health characteristics. Average age was 55,5 years (± 9,8) and average fatigue 6,8 (± 1,6). Compared to participants in the control group participants in the intervention group experienced a significant larger reduction in fatigue severity from baseline to 12 weeks (interaction time*condition: F(3, 1933) = 4.440, p = .004) as well as a significant increase in Quality of Life on average (interaction time*condition: F(3, 1918) = 4.407, p = .004). The effect sizes were small to medium. Analyses show that the intervention effects did not depend on demographic or health characteristics.

  • It may take some time (weeks) before any positive results can be noticed. So, try to keep going and use the app’s education, exercises and tips regularly because the more you practice the more likely you are to see results.

  • There is no indication that using Untire is harmful under any circumstance. Approximately 1-4% of all people may feel more tired in the beginning because they become more aware of their feelings, behavior and body. That disappears after they have been using the app for a while.

    We advise you to consult your doctor before using the app to treat medical causes of the fatigue, if that is the case. If you suffer from serious psychological problems (e.g. depression, psychosis), then those problems must be addressed first.
