Randomized Controlled Trial to Test the Efficacy of an Unguided Online Intervention with Automated Feedback for the Treatment of Insomnia.

Background: Insomnia has become a major public health concern.

Aims: The study examined the efficacy of a web-based unguided self-help programme with automated feedback. The programme was based on cognitive behaviour therapy for insomnia (CBT-I).

Rumination in PTSD as well as in traumatized and non-traumatized depressed patients: a cross-sectional clinical study.

Background: Although rumination is a key process in the onset and maintenance of depressive symptoms and a powerful predictor of persistent posttraumatic stress disorder (PTSD), little is known about the differences and similarities of rumination in these conditions. Previous research has not always differentiated between rumination and intrusive images.

Aims: We sought to systematically evaluate rumination and to gather more information about the content and associated emotions in three patient groups (PTSD, and depressed with and without trauma; n = 65).

Intrusive images in PTSD and in traumatised and non-traumatised depressed patients: a cross-sectional clinical study.

Although intrusive images are a hallmark of post-traumatic stress disorder (PTSD) and also occur in depression, little is known about the differences and similarities of such images in these conditions. Our study focuses on the qualities and triggers of intrusive images and responses to them in three groups--patients with PTSD, and depressed patients with and without trauma (n=65)-to highlight the diagnostic specificity of intrusive images for PTSD and depression. We distinguished intrusive images from verbal intrusive cognitions such as rumination and intrusive (brief) lexical thoughts.
