The relation of attitude towards technology and mastery experience after an app-guided physical exercise intervention: a randomized crossover trial (Preprint)
BACKGROUND Physical exercise has been found to assert a positive impact on many muscular conditions. Exercise under face-to-face supervision is the gold standard, but access to it is limited for instance for economic reasons. App-guided therapy is an intervention that is more affordable and easier accessible. However, attitude towards technology is a key predictor for media adoption and is therefore expected to shape user-experience during app-guided therapy. This might be of particular importance for mastery experience, which are crucial for promoting exercise-related self-efficacy and perceived usefulness of the interaction. Both should empower patients to continuously exercise. OBJECTIVE This study sought to test whether attitudes towards technology predict mastery experience and perceived usefulness of the interaction after an app-versus a physiotherapist-guided treatment. We expect that attitudes towards technology positively predicts both outcomes in case of the app-guided but not in case of the physiotherapist-guided treatment. METHODS Patients (N = 54) with clinically diagnosed hip osteoarthritis participated in two training sessions with the same exercise intervention, once guided by an app on a tablet computer and once guided by a physiotherapist in a German university hospital. The order of the sessions was randomized. Attitude towards technology was assessed as predictor before the first session, mastery experience and the global perceived usefulness of interaction as self-reported outcomes after each session. RESULTS In line with our hypotheses, attitude towards technology predicted mastery experience (b = .16, SE = .07, P = .02) and usefulness of interaction (b = .17, SE = .06, P = .01) after the app-based training but not after the training delivered by a physiotherapist (Ps > .3). Mastery experience was lower for the app-based training but reached a very similar level as the physiotherapist-guided training for those holding a very positive attitude towards technology. CONCLUSIONS The attitude towards technology predicts the extent of mastery experience after app-guided exercise therapy. As mastery experience are highly important for self-efficacy and future exercise behavior, attitudes towards technology should be considered when delivering app-guided exercise treatments.
