Trial Outcomes & Findings for Mobile-Based Application "MyChoices" (NCT NCT03179319)

NCT ID: NCT03179319

Last Updated: 2020-12-16

Results Overview

System Usability Scale: a validated scale that assesses subjective usability of a system, or, in this case, an app. The System Usability Scale consists of a 10 item questionnaire with five response options; from Strongly agree to Strongly disagree. The items scores are converted into a score from 0 (negative) to 100 (positive). A score of ≥50 indicates that the app is acceptable, and a score above 68 is considered above average.

PRIMARY outcome

Timeframe: 3 months

Population: Given that this measure is directly related to the MyChoices app, only those who were randomized to the MyChoices app arm were eligible to respond to this outcome; One person had missing data for this item.

SECONDARY outcome

Timeframe: 3 months

Population: Given that this measure is directly related to the MyChoices app, only those who were randomized to the MyChoices app arm were eligible to respond to this outcome. Due to data collection error in the app (which was subsequently fixed), we are missing data from 7 participants.

The total number of times that participants selected distinct components (e.g., testing plan, ordering, FAQs) of the app were summed
