简要总结
TARA is a Digital Behaviour Change Intervention (DBCI) for Individuals with COPD (IwCOPD), which has been designed using a Human-Centred Design (HCD) methodology. HCD involves, among other elements, members of the target audience in evaluations at multiple stages within the design process.
This feasibility study is primarily designed to assess the acceptability of the DBCI test asset to the target audience. Acceptability as defined for the purpose of this study includes usability of the system, and perceived value and desirability to the end-user audience. As such, engagement in this context is deemed to mean the degree to which the test asset provides a usable, acceptable, desirable and valuable experience to its users during a time-limited trial.

结局指标
主要结局
Patient interaction with TARA (engagement via usage data)
时间窗: up to 3 weeks
Data sourced from individual and amalgamated usage analytics. Data points collected from TARA Patient database / usage analytics, recording the completion with time and date stamps by the users of key sections of the TARA program. An overall score for perceived ease-of-use will be generated using the System Usability Scale (SUS) participant questionnaire
Assessment of usability issues
时间窗: up to 3 weeks
Qualitative assessment of participant's feedback on any usability issues, areas of confusion or lack of clarity whilst using TARA working prototype (version 2). Data sourced from participant's reports, emails and exit interviews.
Assessment of motivation and perception
时间窗: up to 3 weeks
Qualitative assessment of data sourced through the prototype and via discussion in the exit interview
