About this trial
The investigators aim to test the preliminary efficacy as well as the acceptability and feasibility of paradoxical intention, which is a psychotherapeutic technique, for improving insomnia symptoms in adults. Previous research has tested this technique for insomnia and found overall positive results. However, during the last decades very few studies have examined paradoxical intention. Therefore the investigators wish to conduct a pilot study examining the effects in a modern context.
