Study Pilot TRANS-ID tapering: transitions in depressive symptoms during tapering of antidepressants
Investigators Prof. M. Wichers & Dr. E. Snippe
Date Nov 2015 – Jan 2017
Purpose The aim of this pilot study is to examine (1) whether monitoring of daily experiences during and after tapering of antidepressants gives personalized insights in warning signals preceding transitions in depression (2) whether individuals find it helpful to monitor their daily experiences during and after tapering of depressive symptoms. Furthermore, the feasibility of this intensive diary study will be examined and the diary questions included in the study will be evaluated with participants. This is a pilot for the larger TRANS-ID tapering study.
Participants Participants should meet all of the following criteria: – age ≥ 18 – a history of depressive symptoms – having made a shared decision with a mental health care provider to taper the current dose of antidepressant medication – having made a tapering scheme or plan with a mental health care provider

Study No Fun No Glory
Investigators Prof. Tineke Oldehinkel, Dr. Eeske van Roekel, Dr. Charlotte Vrijen, Drs. Vera Heininga, Drs. Maurits Masselink
Date 2015-2016
Purpose This exploratory intervention study is set out to examine effects of tailor-made lifestyle advice, based on observed individual temporal patterns of lifestyle factors and experienced pleasure, as a non-pharmacological means to restore the pleasure of everyday activities and accomplishments. In addition, we will explore whether exposure to tandem skydiving, an experience known to activate the dopamine system and to elicit strong emotions, can help to reboot the reward system and hence foster the recommended lifestyle changes.
