Feasibility and usability of a holistic assessment questionnaire to assess cancer-related fatigue after breast cancer.

PURPOSE: Cancer-related fatigue (CRF) is a major burden for cancer survivors, limiting their functioning in society. Due to the complexity of CRF, a holistic perspective is required to provide treatment advice that aligns with the experience and perpetuating factors of CRF. A holistic assessment of CRF (HA-CRF) questionnaire was developed previously. This study evaluates the feasibility and usability of the HA-CRF questionnaire in daily life to gain insight into the barriers and facilitators for successful implementation into clinical practice.

METHODS

The HA-CRF questionnaire was implemented in an app and used every other week for four weeks by breast cancer survivors (BCS). Feasibility was assessed by adherence to and completion of the HA-CRF questionnaire (compliance), and acceptability was assessed using a questionnaire based on the Unified Theory of Acceptance and Use of Technology model. Usability was assessed during a group interview.

RESULTS

Nineteen BCS participated, of whom eleven also participated in the group interview. While completion rates were high (>75%), adherence to the strict monitoring schedule was low (21%). Acceptability varied. BCS provided suggestions to improve usability, including an overview of the HA-CRF questionnaire use, remembering log-in details, and notifications. BCS suggested personalizing the frequency to their individual situation and a figure to display results.

CONCLUSION

Feasibility and usability were suboptimal although BCS were involved in the development and validation. For optimal use, suggested improvement could resolve the barriers. The HA-CRF questionnaire could aid specialized nurses and BCS as a practical tool to assess and manage CRF.
