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 Idiographic study of Cognitive function, Affect, and Sleep in Early Alzheimer (i-CASE)
Investigators Dr. Marij Zuidersma, Prof. Richard Oude Voshaar
Date February 2014 – June 2019
Purpose 1) Evaluate the temporal dynamics between sleep disturbances, depression and cognitive function within elderly individuals with cognitive impairments and depression.2) Evaluate whether other (time-varying and time-stable) variables, such as the circadian rhythm, the presence of somatic diseases and physical activity affect the temporal relationship between sleep disturbances, depression and cognitive function within the individual3) Evaluate whether giving feedback on personal triggers for cognitive impairments, depression and sleep disturbances to patients gives insight to these patients and is helpful for them
Participants 20 Patients with mild cognitive impairments of mild dementia due to Alzheimer’s disease, and with depression (according to MINI or GDS>=4).
Study NESDA diary study
Investigators Dr H. Riese, Prof Dr R.A. Schoevers, Dr F. Lamers, Dr L. Boschloo, Prof Dr P. de Jonge
Date 2014 – 2017
Purpose The main aim of this study is to provide new insights into the nature of daily mood fluctuations that can explain the differences in severity and nature of mood disorder beyond the traditional DSM classifications.
Participants 400 patients with mood disorders, their sibs and healthy controls
Study Simvastatine-study
Investigators Prof. Dr. I.E.C. Sommer, Prof. W. Veling, Prof. R. Bruggeman, Dr. M. Begemann, Dr. S Schuite-Koops, S.Gangadin, M. Bak, E. van ’t Hag
Date September 2013 – December 2019
Purpose To evaluate whether simvastatin addition improves symptoms, cognition, metabolic syndrome and movement disorders in patients with recent-onset psychotic disorder.
Participants 121 patients with psychotic disorder
Study TRENSS 2
Investigators Drs. C. Kos, Prof. Dr. A. Aleman
Date September 2012- May 2018
Purpose The main objective is to investigate whether treatment using neurostimulation (tDCS or rTMS) targeting the rDLPFC reduces apathy in schizophrenia patients by activating the targeted brain region and whether tDCS is equally effective as rTMS. A secondary aim is to evaluate if a psychosocial intervention, in the form of BAT, in addition to a biological intervention, TMS, further reduces the level of apathy.
Participants 125 schizophrenia patients
Study Blues Clues
Investigators Dr. M. aan het Rot, K. Hogenelst, M.Sc., Prof. Dr. R.A. Schoevers
Date April 2012 – August 2014

Study Trichotillomanics
Investigators S.D.M. van Dijk, Dr. E.H. Bos
Date February 2012
Purpose To investigate the usefulness of the Psymate as an intervention tool in Trichotillomanics
Participants 1 patient with trichotillomanics
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.
