Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main outcome measures are the Quick Inventory of Depressive Symptoms (QIDS-SR), the Hamilton Depression Rating Scale (HDRS), the Remission from Depression Questionnaire (RDQ) and change in AA between frontal cortical regions. • The QIDS-SR is a 16-item self-rating scale to assess symptom severity of MDD and will be administered prior to each NF session (3 times a week). • The HDRS is a 17-item clinician-rated scale for estimating severity of depression during the past week. It will be administered once a week by a trained research assistant during the 6-week study period. • The RDQ is a 41-item self-rating scale that measures symptomatic and functional remission from depression. It will be administrated once a week during the 6-week study period. • AA in frontal regions (F3-F4) will be calculated as described in the intervention paragraph above. Based on results from our studies in healthy volunteers and depressed participants, no changes in AA in the sham-condition can be expected as opposed to significant decreases in AA in the active condition. | — |
