698.4 - DSM 5 - Skin Picking Disorder
Conditions
Interventions
Group 1: The SPD patients are randomly assigned to the ‘Soft Touch Training’ (STT
daily training à 15 min for 4 weeks). Before and after the 4-week STT/PMR, an fMRI experiment with slow and fast brushing of the skin will be conducted.
Group 2: The SPD patients are randomly assigned
daily training (à 15 min) for 4 weeks). Before and after the 4-week STT/PMR, an fMRI experiment with slow and fast brushing of the skin will be conducted.
Group 3: Controls undergo slow/fast/no brushi

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is predicted that the touch training will reduce symptom severity of SPD (self-report) and will lead to increased neural activity and connectivity (insula, somatosensory cortex, striatum, prefrontal regions, thalamus) during soft brushing (functional magnetic resonance imaging). Assessment: directly after termination of the 4-week training; comparison with pre-training assessment | — |
Secondary
| Measure | Time frame |
|---|---|
| Exploratory studies will be conducted to investigate whether tactile training leads to changes in the volume of grey matter in the regions of interest (magnetic resonance imaging; voxel-based morphometry). Assessment: directly after termination of the 4-week training; comparison with pre-traiining assessment | — |
