Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary end point of the study is the assessment of performance on neuropsychological task on emotion recognition and emotion regulation (correct responses (i.e., action or classification) and response time (i.e., in milliseconds)). Adolescents repeat three neuropsychological task to assess emotion processing and emotion regulation under tVNS and sham. Emotion recognition is measured by the participants’ capability to correctly recognize (Test 1) and rate the intensity (Test 2) of key facial expressions using computerized task. The task comprises sets of stimuli that are presented cross-randomized (tVNS vs. sham). Reaction time in milliseconds and correct classifications are measured as outcome. Changes in emotion regulation are assessed using the emotional Go/No-Go paradigm (Test 3). The paradigm involves a continuously presented series of faces of certain emotional valences (e.g., happy, angry) composed of frequent “Go” cues (i.e. angry faces) to which patients respond as rapidly as possible (pressing key on keyboard) and infrequent “No-Go” (i.e., happy faces) cues to which patients do not respond and inhibit their response. | — |
Secondary
| Measure | Time frame |
|---|---|
| A continous ECG is recorded to quantify changes in heart rate varaibility and functional near infrared spectroscopy (fNIRS) is used to quantify oxygenation of the prefrontal cortex as secondary endpoints of the trial. | — |
