Effects of Induced Mindfulness at Night on Repetitive Negative Thinking: Ecological Momentary Assessment Study.

Background: Repetitive negative thinking (RNT) is a cognitive risk factor for various disorders. Although brief mindfulness-based interventions (MBIs; lasting 20-30 minutes or shorter) are effective tools to reduce RNT, the effect of a minimal (5-minute) MBI remains largely unknown.

Objective: We investigated the acute changes in RNT induced by a 10-day minimal MBI (body scan before sleeping) using an ecological momentary assessment (EMA) administered during the MBI training phase.

Positive Emotion Dysregulation in Posttraumatic Stress Disorder.

Although PTSD is associated with both emotion regulation (ER) difficulties and persistent difficulties experiencing positive emotions, research concerning positive ER in PTSD is still scarce. We aimed to clarify whether PTSD patients show dysfunctional responses to positive emotions and whether positive ER is associated with PTSD symptom severity. PTSD patients (N = 59) were compared to healthy controls (HC, N = 58) with respect to their self-reported regulation of positive and negative emotions.
