Attributional style in psychosis--the role of affect and belief type

People holding persecutory beliefs have been hypothesised to show a self-serving attributional style, which functions to protect self-esteem Bentall, Corcoran, Howard, Blackwood, and Kinderman (2001). Experimental support for this has been mixed. Freeman et al. (1998) suggested depressed and grandiose subgroups of those with persecutory beliefs might explain events differently. In this study, 71 participants completed measures of delusional beliefs, depression and attributional style. We hypothesised that those with persecutory beliefs would form grandiose and depressed subgroups, and that a self-serving attributional style would characterise only the grandiose subgroup. Hypotheses were partially confirmed. Clear subgroups were evident and only those with both persecutory and grandiose beliefs showed an externalising attributional style for negative events. Depression, irrespective of co-occurring persecutory beliefs, was related to a reduced self-serving bias and an externalising attributional style for positive events. On their own, persecutory beliefs were not related to any particular attributional style. Depressed and grandiose subgroups of those with persecutory beliefs might account for some of the inconsistencies in the attribution literature. Even within a single symptom group, care should be taken in both research and therapy to consider individual symptom patterns.     

Acting on persecutory delusions: the importance of safety seeking

OBJECTIVE: Acting on delusions is a significant clinical issue. The concept of safety behaviours--actions carried out with the intention of reducing perceived threat--provides a new way of understanding acting on delusions. A study was conducted with the aim of examining the prevalence and correlates of safety behaviours related to persecutory delusions. METHOD: One hundred patients with persecutory delusions were assessed for safety behaviours, acting on delusions, anxiety, depression, and psychotic symptoms. Case note data were collected on instances of serious violence or suicide attempts. RESULTS: Ninety-six patients had used safety behaviours in the last month. Greater use of safety behaviours was associated with higher levels of distress. A history of violence or suicide attempts was associated with greater use of safety behaviours. Safety behaviours were significantly associated with acting on delusions, but not with the negative symptoms of psychosis. CONCLUSION: Safety behaviours are a common form of acting on persecutory delusions. These behaviours have the consequence that they are likely to prevent the processing of disconfirmatory evidence and will therefore contribute to delusion persistence.     

Persecutory delusions and catastrophic worry in psychosis: developing the understanding of delusion distress and persistence

In a recent theoretical account of persecutory delusions, it is suggested that anxiety and worry are important factors in paranoid experience [Freeman, D., Garety, P. A., Kuipers, E., Fowler, D., & Bebbington, P. E. (2002). A cognitive model of persecutory delusions. British Journal of Clinical Psychology, 41(4), 331-347]. In emotional disorders worry has been understood in terms of catastrophising. In the current study, the concept of catastrophising is applied for the first time with persecutory delusions. Thirty individuals with current persecutory delusions and 30 non-clinical controls participated in a cross-sectional study. The group with persecutory delusions was also followed up at 3 months to assess predictors of delusion persistence. At its most severe, 21% of individuals with persecutory delusions had clinical worry, 68% had levels of worry comparable with treatment seeking GAD patients. Further, high levels of anxiety, worry and catastrophising were associated with high levels of persecutory delusion distress and with the persistence of delusions over 3 months. If future research replicates these findings, worry reduction interventions for individuals with persecutory delusions may be warranted.     

Posttraumatic Growth Following Trauma: Is Growth Accelerated or a Reflection of Cognitive Maturation?

Over the past two decades, there has been an exponential increase in studies investigating posttraumatic growth (PTG) in samples exposed to various traumatic experiences. The prevalence of PTG following trauma has been variable, and mixed findings have emerged pertaining to factors associated with PTG. To date, however, there has been a notable paucity of research that has considered the PTG phenomenon in relation to lifespan developmental, cognitive, and humanistic theories. The objective of this review is to evaluate the prominent theory of PTG proposed by Tedeschi and Calhoun (1996 Tedeschi, R. G. & Calhoun, L. G. (1996). The posttraumatic growth inventory: Measuring the positive legacy of trauma. Journal of Traumatic Stress, 9, 455–471.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) in context of the theories of Erikson and Maslow, as well as Frankl's theory of meaning-making postadversity. Methodological issues are also considered to inform the advancement of future research in this field.     

Jumping to conclusions, a lack of belief flexibility and delusional conviction in psychosis: a longitudinal investigation of the structure, frequency, and relatedness of reasoning biases

Two reasoning biases, jumping to conclusions (JTC) and belief inflexibility, have been found to be associated with delusions. We examined these biases and their relationship with delusional conviction in a longitudinal cohort of people with schizophrenia-spectrum psychosis. We hypothesized that JTC, lack of belief flexibility, and delusional conviction would form distinct factors, and that JTC and lack of belief flexibility would predict less change in delusional conviction over time. Two hundred seventy-three patients with delusions were assessed over twelve months of a treatment trial (Garety et al., 2008). Forty-one percent of the sample had 100% conviction in their delusions, 50% showed a JTC bias, and 50%-75% showed a lack of belief flexibility. Delusional conviction, JTC, and belief flexibility formed distinct factors although conviction was negatively correlated with belief flexibility. Conviction declined slightly over the year in this established psychosis group, whereas the reasoning biases were stable. There was little evidence that reasoning predicted the slight decline in conviction. The degree to which people believe their delusions, their ability to think that they may be mistaken and to consider alternative explanations, and their hastiness in decision making are three distinct processes although belief flexibility and conviction are related. In this established psychosis sample, reasoning biases changed little in response to medication or psychological therapy. Required now is examination of these processes in psychosis groups where there is greater change in delusion conviction, as well as tests of the effects on delusions when these reasoning biases are specifically targeted.     

Do young infants respond socially to human hands?

This study revealed that 4- and 6-month-old infants produced social-communicative behaviours only in response to faces, and not in response to hands. However, infants’ spontaneous responses to hands were unique in that they scanned the space above the hands, perhaps searching for a face.     

Negotiating Public and Professional Interests: A Rhetorical Analysis of the Debate Concerning the Regulation of Midwifery in Ontario, Canada

This article investigates the uneasy process of integrating midwifery's alternative, women-centered model of childbirth care within the medically-dominated healthcare system in Canada. It analyses the impure processes of rhetorical identification and differentiation that characterized the debate about how to regulate midwifery in Ontario by examining a selection of submissions from diverse health care groups with vested interest in the debate's outcome. In divergent ways, these groups strategically appeal to the value of the "public interest" in order to advance professional concerns. The study considers the implications of this rhetorical process for re-defining midwifery's distinctive professional identity in relation to other health professions, to the state, and to the women for whom midwives care. Likewise, it suggests the relevance of rhetorical analysis for understanding the discursive formation and re-formation of health models, values, and professions in Western culture.     

Reasoning, emotions, and delusional conviction in psychosis

The aim of the study was to elucidate the factors contributing to the severity and persistence of delusional conviction. One hundred participants with current delusions, recruited for a treatment trial of psychological therapy (PRP trial), were assessed at baseline on measures of reasoning, emotions, and dimensions of delusional experience. Reasoning biases (belief inflexibility, jumping to conclusions, and extreme responding) were found to be present in one half of the sample. The hypothesis was confirmed that reasoning biases would be related to delusional conviction. There was evidence that belief inflexibility mediated the relationship between jumping to conclusions and delusional conviction. Emotional states were not associated with the reasoning processes investigated. Anxiety, but not depression, made an independent contribution to delusional conviction.     

Increasing access to psychological therapies for people with psychosis: predictors of successful training

BackgroundCognitive behavioural therapy for psychosis (CBTp) is recommended for people with schizophrenia, but routine delivery remains limited. Obstacles to increasing access include inadequate training, organisational support and supervision, resulting in low levels of staff competence and confidence. This study is a preliminary evaluation of a CBTp training programme, designed to overcome these obstacles and to increase routine delivery of competent CBTp.MethodTraining outcomes for a pilot group and for the first three cohorts to complete training were analysed to identify predictors of successful completion and of therapy delivery after training.ResultsObjective competence was attained by 37 students (out of 58), who delivered therapy to over 160 service users. Successful completion was associated with previous CBT therapy experience. Delivery after one year was associated with working in a therapy rather than a care co-ordination role.ConclusionsThe programme succeeded in training therapists to deliver competent therapy. Our results suggest that preliminary training in CBT for other disorders may improve success rates in CBTp. Despite extensive service liaison, delivery remained problematic for care co-ordinators without role change and provision of dedicated time. The findings should inform future implementation strategies.
