Moment-to-moment affective dynamics in schizophrenia and bipolar disorder.

Background: Affective disturbances in schizophrenia and bipolar disorder may represent a transdiagnostic etiological process as well as a target of intervention. Hypotheses on similarities and differences in various parameters of affective dynamics (intensity, successive/acute changes, variability, and reactivity to stress) between the two disorders were tested.

Methods: Experience sampling method was used to assess dynamics of positive and negative affect, 10 times a day over 6 consecutive days.

A randomised controlled trial of metacognitive training for psychosis, depression, and belief flexibility.

Background: Metacognitive training (MCT) has been shown to be effective in reducing psychotic symptoms, including delusions. However, less is known on whether MCT, or its specific modules, are effective in ameliorating reasoning biases e.g.

Moment-to-moment dynamics between auditory verbal hallucinations and negative affect and the role of beliefs about voices.

Background: Negative affect (NA) has been suggested to be both an antecedent and a consequence of auditory verbal hallucinations (AVH). Furthermore, negative appraisals of voices have been theorized to contribute to the maintenance of AVH. Using the experience sampling method (ESM), this study examined the bi-directional relationship between NA and AVH, and the moderating effect of negative beliefs about voices.
