[Interpersonal psychotherapy in treatment of patients with primary insomnia--preliminary data of polysomnographic macro-analysis].

There has not been done much research on psychotherapeutic treatment of patients with primary insomnia. Interpersonal psychotherapy for insomnia (IPT-I) represents a new causal strategy in the treatment of insomnia, which has been evaluated in this study. 25 patients were treated in 12 single sessions either with IPT-I or with progressive relaxation training. Preliminary polysomnographic data show significant improvement of total sleep time, sleep efficiency and wake after sleep onset of the IPT-I-patients, while the PR-patients only improved slightly. IPT-I therefore was shown to be a promising strategy in the treatment of patients with primary insomnia.
