The effect of the light therapy is evaluated by means of the Self-Rated Quick Inventory of Depressive Symptoms (QIDS-SR). Further treatment strategy is determined on the basis of these results:~* If the patient has achieved remission (QIDS-SR \< 6), BLT has been successful and the patient can continue with PE and IMCT.~* If there is insufficient or no response (QIDS-SR of 6 or higher), BLT is extended with five more sessions the following week.~* If necessary, a third week is optional.~Week 2-4: Psycho Education will follow, 1 session.~Week 3/4-9/10: ImCT will follow, 6 sessions."
