Reactivity to smartphone-based ecological momentary assessment of depressive symptoms (MoodMonitor):protocol of a randomised controlled trial

BACKGROUND: Ecological momentary assessment (EMA) of mental health symptoms may influence the symptoms that it measures, i.e. assessment reactivity. In the field of depression, EMA reactivity has received little attention. We aim to investigate whether EMA of depressive symptoms induces assessment reactivity. Reactivity will be operationalised as an effect of EMA on depressive symptoms measured by a retrospective questionnaire, and, secondly, as a change in response rate and variance of the EMA ratings. METHODS: This study is a 12-week randomised controlled trial comprising three groups: group... Mehr ...
