Usability, acceptability and safety analysis of a computer-tailored web-based exercise intervention (ExerciseGuide) for individuals with metastatic prostate cancer: A multi-methods lab-based study.
ABSTRACT
Background:
Digital health interventions such as tailored websites are emerging as valuable tools to provide individualised exercise and behavioural change information for individuals diagnosed with cancer.
Objective:
The purpose of this research was to investigate and iteratively refine the acceptability and usability of a web-based exercise intervention (ExerciseGuide) for men with metastatic prostate cancer and determine how well individuals can replicate the video-based exercise prescription.
Methods:
A laboratory-based mixed-methods design was employed, incorporating questionnaires, think-aloud tests, interviews, and movement screening among eleven men aged 63 to 82 with metastatic prostate cancer. Nine participants were undergoing androgen deprivation therapy, and two were completing chemotherapy. Data was collected in two waves with changes made for quality improvement after participant five.
Results:
The intervention's usability score was deemed moderate overall but improved after modifications (from 60.0 ± 2.9 to 69.6 ± 2.2 out of 100). After wave one, website navigation videos were added, medical terminology was simplified, and a telehealth component was included to aid participant support. Participants found the intervention acceptable, with scores improving from wave 1 (24.2 ± 1.1 out of 30) to wave 2 (26.3 ± 2.1 out of 30). The personalised multi-modal exercise prescription and computer-tailored education seen as valuable. The inclusion of expert telehealth support was considered of high importance. The Participants could replicate the resistance exercise videos to a satisfactory level as judged by the movement screen; however, additional technique cueing within the videos is recommended to address safety concerns.
Conclusions:
The acceptability and usability of ExerciseGuide was deemed satisfactory but could be enhanced by expert telehealth support. This research has optimised the ExerciseGuide intervention for further investigation in this population. Clinical Trial: Trial registration: ANZCTR, ACTRN12618001978257
