Group-Based Worry Intervention for Persecutory Delusions: an Initial Feasibility Study.

Background: A one-to-one cognitive behavioural therapy intervention targeting worry significantly reduces both worry and persecutory delusions (Freeman et al., 2015).

Aim: To adapt this intervention for group delivery and conduct a feasibility trial within routine clinical practice.

Jumping to perceptions and to conclusions: specificity to hallucinations and delusions.

Background: There is evidence that people with psychosis display a "jump-to-conclusions" (JTC) reasoning style, and that this bias may be specific to delusions. A "jump-to-perceptions" (JTP) cognitive bias has also been found and is typically linked to hallucinations. However, there is some evidence for an association between JTP and delusions, and its specificity to hallucinations remains unclear.

Cognitive predictors of social functioning improvements following cognitive remediation for schizophrenia.

A greater understanding of the links between cognitive and social functioning changes is needed to refine cognitive treatments for schizophrenia. To date, studies have been cross-sectional, and few have investigated the impact of cognitive change. This single-blind randomized controlled trial explored the links between changes in executive/memory functions and social behavior, as well as the moderating effect of cognitive remediation therapy (CRT).
