NCT05830318 | Completed Results

• 1 other identifier: 0901
• Study Type: observational
• Target: 178
• Locations: 1 country
• Sites: 1

Brief Summary

Assess the usability and acceptance of the P-STEP app, through allowing participants with specific chronic conditions to pilot the app for 12-weeks.

Conditions

Asthma; Interstitial Lung Disease; Coronary Heart Disease; Heart Failure; Type 2 Diabetes; Chronic Obstructive Pulmonary Disease

Keywords

Exercise; Pollution; Air Quality

Outcome Measures

Primary Outcomes (1)

• System Usability Scale

  the System Usability Scale (SUS) at 12 weeks. The SUS a validated scale and a popular instrument for assessing perceived usability. There are 10 items in total, 5 with a positive tone and 5 with a negative tone, the response of each ranging from strongly disagree to strongly agree. The participant's scores will be transformed onto a 0-100 scale. General guidance suggests a SUS score 68 and above to be considered above average and below 68 is below average. Scores range from 0-100, a higher score indicates higher usability.

Limitations and Caveats

This study did not appeal greatly to individuals in this cohort. There are a number of possible reasons for this. Firstly, there may be a reluctance in this cohort to take part in app studies for a number of reasons including confidence using technology and security concerns in testing an app in the investigational stages of development. The time of year of the study may have also affected take up. The study ran from September to January, bad weather
