Development and Usability Testing of the ATOMIC Mobile App to Increase Physical Activity (PA) Levels in Children, Adolescent and Young Adults (AYA) Survivors of Childhood Cancer

Development and Usability Testing of the ATOMIC Mobile App to Increase Physical Activity (PA) Levels in Children, Adolescent and Young Adults (AYA) survivors of childhood cancer

Study Overview

Status

Active, not recruiting

Conditions

Intervention / Treatment

Detailed Description

The purpose of this program of research is to (1) determine the adaptations required of a pre-existing mobile fitness app to tailor it for childhood cancer survivors using a behavioral theory driven approach (Social Cognitive Theory) and (2) develop and evaluate the usability of the adapted mobile app using the Technology Assessment Model. The Technology Assessment Model (TAM), which theorizes the individuals' intentions to use information technology, is based on two driving factors: perceived usefulness and perceived ease of use. Future studies will evaluate the feasibility and effectiveness of this app.

  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Real life usability testing
B) "Real Life" Usability Testing. We will conduct a "real life" usability test in a sample of 6 pediatric cancer survivors. EX@HOME: Patients will perform an individualized aerobic and resistance exercise intervention, choosing from a list of PA, progressing from light to moderate-to-vigorous intensity totaling 30-45 min/d, 4-5 weekly/wk. for 4 weeks. The social-cognitive-theory-based mobile app will support the exercise intervention. One-on-one messaging chats with a PA coach through the mobile app will facilitate exercise goal establishment and attainment.
Other: Atomic app
Using the Atomic app to improve physical activity

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Ease of use and user errors will be documented for each individual during usability testing, by completing several tasks while navigating the mobile app platform
Time Frame: 1 year
The interviewers will record how well the participants are able to navigate the task by recording either "easy to find", "with prompting", or "unable to complete", representing completing the task completely on their own, with help from the interviewer, or unable to complete after prompting from the interviewer. The frequency of user errors will be calculated.
1 year
The Acceptability E-Scale is six-item tool that has been validated for assessing the usability, acceptability, and satisfaction of web based programs with statements ranked on a five point scale from very difficult to very easy
Time Frame: 1 year
Acceptability of a program has been proposed to be represented by obtaining a score of 24 or more.81 Good internal consistency (alpha = 0.76) as well as good initial validity has been reported. The acceptability E-scale will be administered at the completion of the "in laboratory" testing and "real-life" usability testing.
