Abstract
BACKGROUND Involving stakeholders and consumers throughout the content and study design ensures interventions are engaging and relevant for end users The aim of this paper is to present the content development process for a mHealth mobile phone and internet based cardiac rehabilitation CR exercise intervention METHODS An innovative mHealth intervention was developed with patient input using the following steps conceptualization formative research pre testing and pilot testing Conceptualization including theoretical and technical aspects was undertaken by experts For the formative component focus groups and interviews with cardiac patients were conducted to discuss their perceptions of a mHealth CR program A general inductive thematic approach identified common themes A preliminary library of text and video messages were then developed Participants were recruited from CR education sessions to pre test and provide feedback on the content using an online survey Common responses were extracted and compiled An iterative process was used to refine content prior to pilot testing and conduct of a randomized controlled trial RESULTS 38 CR patients and 3 CR nurses participated in the formative research and 20 CR patients participated in the content pre testing Participants perceived the mHealth program as an effective approach to inform and motivate patients to exercise For the qualitative study 100 n 41 of participants thought it to be a good idea and 11 of participants felt it might not be useful for them but would be for others Of the 20 participants who completed the online survey 17 out of 20 85 stated they would sign up to a program where they could receive information by video messages on a website and 12 out of 20 60 showed interest in a texting program Some older CR patients viewed technology as a potential barrier as they were unfamiliar with text messaging or did not have mobile phones Steps to instruct participants to receive texts and view the website were written into the study protocol Suggestions to improve videos and wording of texts were fed back to the content development team and refined CONCLUSIONS Most participants thought a mHealth exercise program was an effective way to deliver exercise based CR The results were used to develop an innovative multimedia exercise intervention A randomized controlled trial is currently underway TRIAL REGISTRATION ACTRN12611000117910
