Imagery re-scripting for PTSD: session content and its relation to symptom improvement.

Imagery rescripting (ImRs) is a therapy technique that, unlike traditional re-living techniques, focuses less on exposure and verbal challenging of cognitions and instead encourages patients to directly transform the intrusive imagery to change the depicted course of events in a more desired direction. However, a comprehensive account of how and in what circumstances ImRs brings about therapeutic change is required if treatment is to be optimised, and this is yet to be developed. The present study reports on the development of a coding scheme of ImRs psychotherapy elements identified in the literature as potential ImRs mechanisms. The codes were assessed in relation to short-term outcomes of 27 individuals undergoing ImRs for post-traumatic stress disorder. The timing of the change in the image, degree of activation of the new image and associated cognitive, emotional and physiological processes, self-guided rescripting, rescript believability, narrative coherence and cognitive and emotional shift were identified as being related to symptom change and so are potentially important factors for the re-scripting process.

Survivor Guilt: A Cognitive Approach.

Survivor guilt is a common experience following traumatic events in which others have died. However, little research has addressed the phenomenology of survivor guilt, nor has the issue been conceptualised using contemporary psychological models which would help guide clinicians in effective treatment approaches for this distressing problem. This paper summarises the current survivor guilt research literature and psychological models from related areas, such as posttraumatic stress disorder, moral injury and traumatic bereavement. Based on this literature, a preliminary cognitive approach to survivor guilt is proposed. A cognitive conceptualisation is described, and used as a basis to suggest potential treatment interventions for survivor guilt. Both the model and treatment strategies require further detailed study and empirical validation, but provide testable hypotheses to stimulate further research in this area.

Treatment of survivor guilt after trauma using imagery rescripting: a proof-of-concept study.

Survivor guilt can arise after surviving a trauma in which others die. No studies have systematically investigated psychological treatment for survivor guilt. The present study was a proof-of-concept investigation of treatment of survivor guilt using imagery rescripting. Thirteen participants with post-traumatic stress disorder and self-reported survivor guilt attended two consecutive imagery therapy sessions, to first elaborate and then rescript related imagery. Significant improvements were observed on idiographic process measures of cognitons, emotions and distress related to survivor guilt following the rescripting session. The study provides preliminary evidence that imagery rescripting can be used as an experiential technique to treat survivor guilt.

Evaluating an early intervention in psychosis service for 'high-risk' adolescents: symptomatic and social recovery outcomes.

AIM: This study presents client characteristics and treatment outcomes for a group of young people seen by Central Norfolk Early Intervention Team (CNEIT). The team offers an intensive outreach model of treatment to young people with complex co-morbid emotional, behavioural and social problems, as well as the presence of psychotic symptoms. METHODS: Outcomes include both client self-report and clinician-rated measures. Data are routinely collected at acceptance into service, after 12 months of service and at point of discharge. RESULTS: Data show that clients seen by the CNEIT youth team are a group of young people at high risk of developing long-term mental illness and social disability. Outcomes show significant reductions in not only psychotic symptomatology, but also co-morbid anxiety and depression, as well as improvements in social recovery. At the end of their time with the service, the majority of clients are discharged back to the care of their general practitioner, which indicates that the team successfully managed to reduce the complexity of needs and difficulties associated with this client group. CONCLUSIONS: Outcomes support the use of an intensive outreach approach for young people at high risk of developing psychotic disorders. It has been suggested that this model may be successfully broadened to young people with other emerging, potentially severe or complex mental disorders. Norfolk and Suffolk NHS Foundation Trust has built on the success of its youth early intervention team and innovatively redesigned its services in line with this model by developing a specific youth mental health service.

Jumping to the wrong conclusions? An investigation of the mechanisms of reasoning errors in delusions.

Understanding how people with delusions arrive at false conclusions is central to the refinement of cognitive behavioural interventions. Making hasty decisions based on limited data ('jumping to conclusions', JTC) is one potential causal mechanism, but reasoning errors may also result from other processes. In this study, we investigated the correlates of reasoning errors under differing task conditions in 204 participants with schizophrenia spectrum psychosis who completed three probabilistic reasoning tasks. Psychotic symptoms, affect, and IQ were also evaluated. We found that hasty decision makers were more likely to draw false conclusions, but only 37% of their reasoning errors were consistent with the limited data they had gathered. The remainder directly contradicted all the presented evidence. Reasoning errors showed task-dependent associations with IQ, affect, and psychotic symptoms. We conclude that limited data-gathering contributes to false conclusions but is not the only mechanism involved. Delusions may also be maintained by a tendency to disregard evidence. Low IQ and emotional biases may contribute to reasoning errors in more complex situations. Cognitive strategies to reduce reasoning errors should therefore extend beyond encouragement to gather more data, and incorporate interventions focused directly on these difficulties.

Identifying cognitive remediation change through computational modelling--effects on reinforcement learning in schizophrenia.

OBJECTIVE: Converging research suggests that individuals with schizophrenia show a marked impairment in reinforcement learning, particularly in tasks requiring flexibility and adaptation. The problem has been associated with dopamine reward systems. This study explores, for the first time, the characteristics of this impairment and how it is affected by a behavioral intervention-cognitive remediation. METHOD: Using computational modelling, 3 reinforcement learning parameters based on the Wisconsin Card Sorting Test (WCST) trial-by-trial performance were estimated: R (reward sensitivity), P (punishment sensitivity), and D (choice consistency). In Study 1 the parameters were compared between a group of individuals with schizophrenia (n = 100) and a healthy control group (n = 50). In Study 2 the effect of cognitive remediation therapy (CRT) on these parameters was assessed in 2 groups of individuals with schizophrenia, one receiving CRT (n = 37) and the other receiving treatment as usual (TAU, n = 34). RESULTS: In Study 1 individuals with schizophrenia showed impairment in the R and P parameters compared with healthy controls. Study 2 demonstrated that sensitivity to negative feedback (P) and reward (R) improved in the CRT group after therapy compared with the TAU group. R and P parameter change correlated with WCST outputs. Improvements in R and P after CRT were associated with working memory gains and reduction of negative symptoms, respectively. CONCLUSION: Schizophrenia reinforcement learning difficulties negatively influence performance in shift learning tasks. CRT can improve sensitivity to reward and punishment. Identifying parameters that show change may be useful in experimental medicine studies to identify cognitive domains susceptible to improvement.
