A Randomized Experimental Investigation of Reasoning Training for People With Delusions

The present study aimed to investigate whether a brief reasoning training module changes the “jumping to conclusions” data gathering bias in people with delusions. A secondary aim was to examine whether improvements in reasoning would lead to greater flexibility in thinking about delusions. It was found that people with delusions and a diagnosis of schizophrenia (n = 34) requested less information on a reasoning task compared with a nonclinical control group (n = 34). The clinical group was then randomly allocated to a session of reasoning training or to an attention control condition. Following training, participants showed a significant increase in data gathering, and a small number reported more flexibility and less conviction in their delusions, although this finding was not significant. The presence at baseline of an extreme reasoning bias moderated the effect of training. The study provides further confirmation of the jumping to conclusions bias and shows that data gathering can be improved, though the severest form of the bias is resistant to change. It is recommended that lengthier, delusion-related reasoning packages be developed and evaluated

Effective elements of cognitive behaviour therapy for psychosis: results of a novel type of subgroup analysis based on principal stratification

Background. Meta-analyses show that cognitive behaviour therapy for psychosis (CBT-P) improves distressing positive symptoms. However, it is a complex intervention involving a range of techniques. No previous study has assessed the delivery of the different elements of treatment and their effect on outcome. Our aim was to assess the differential effect of type of treatment delivered on the effectiveness of CBT-P, using novel statistical methodology. Method. The Psychological Prevention of Relapse in Psychosis (PRP) trial was a multi-centre randomized controlled trial (RCT) that compared CBT-P with treatment as usual (TAU). Therapy was manualized, and detailed evaluations of therapy delivery and client engagement were made. Follow-up assessments were made at 12 and 24 months. In a planned analysis, we applied principal stratification (involving structural equation modelling with finite mixtures) to estimate intention-to-treat (ITT) effects for subgroups of participants, defined by qualitative and quantitative differences in receipt of therapy, while maintaining the constraints of randomization. Results. Consistent delivery of full therapy, including specific cognitive and behavioural techniques, was associated with clinically and statistically significant increases in months in remission, and decreases in psychotic and affective symptoms. Delivery of partial therapy involving engagement and assessment was not effective. Conclusions. Our analyses suggest that CBT-P is of significant benefit on multiple outcomes to patients able to engage in the full range of therapy procedures. The novel statistical methods illustrated in this report have general application to the evaluation of heterogeneity in the effects of treatment

Paranoid thinking, cognitive bias and dangerous neighbourhoods: implications for perception of threat and expectation of victimisation

Background: Paranoid thinking is prevalent in the non-clinical population and cognitive mechanisms of heuristic reasoning and jumping to conclusions bias contributes to its formation and maintenance. Aims: This study investigated the degree to which paranoia, perceived environmental risk, heuristic reasoning and jumping to conclusions bias (measured with the beads task) contribute to misinterpretation of neutral stimuli, and whether this informed judgements regarding vulnerability to threat and crime. It is also investigated whether impulsiveness is a confounding factor on the beads task. Methods: Two hundred participants were recruited using a snowball-sampling method for a quantitative cross-sectional study. Participants reported demographic information, three psychometric questionnaires and two experimental tasks via an online paradigm hosted by the Bristol Online Survey tool. Results: Participants with high paranoia scores perceived their environment to be more dangerous than those with low scores. Participants with high paranoia scores also overestimated threat in neutral stimuli and had high expectations of future victimisation. Jumping to conclusions on the beads task did not predict fear of crime outcomes, but was predicted by impulsivity. Conclusion: Participants who demonstrated paranoid thinking were more likely to reside in perceived dangerous neighbourhoods and overestimate threat. While this could indicate a paranoid heuristic, it is a potentially rational response to prior experiences of crime and victimisation. Implications and suggestions for future research are discussed

Orbitofrontal cortex, emotional decision-making and response to cognitive behavioural therapy for psychosis

Grey matter volume (GMV) in the orbitofrontal cortex (OFC) may relate to better response to cognitive behavioural therapy for psychosis (CBTp) because of the region's role in emotional decision-making and cognitive flexibility. This study aimed to determine the relation between pre-therapy OFC GMV or asymmetry and CBTp responsiveness and emotional decision-making as measured by the Iowa Gambling Task (IGT). Thirty patients received CBTp + standard care (CBTp+SC; 25 completers) for 6-8 months. All patients (before receiving CBTp) and 25 healthy participants underwent structural magnetic resonance imaging and performed the IGT. Patients' symptoms were assessed before and after therapy. Pre-therapy OFC GMV, measured using a region-of-interest approach, and IGT performance, measured as overall learning, attention to reward, memory for past outcomes and choice consistency, were comparable between patient and healthy groups. In the CBTp+SC group, greater OFC GMV was correlated with positive symptom improvement, specifically hallucinations and persecution. Greater rightward OFC asymmetry correlated with improvement in several negative and general psychopathology symptoms. Greater left OFC GMV was associated with lower IGT attention to reward. The findings suggest that greater OFC volume and rightward asymmetry, which maintain the OFC's function in emotional decision-making and cognitive flexibility, are beneficial for CBTp responsiveness

Relating behaviours and therapeutic actions during AVATAR therapy dialogue: an observational study

OBJECTIVES: AVATAR therapy is a novel relational approach to working with distressing voices by engaging individuals in direct dialogue with a digital representation of their persecutory voice (the avatar). Critical to this approach is the avatar transition from abusive to conciliatory during the course of therapy. To date, no observational study has examined the moment-to-moment dialogical exchanges of this innovative therapy. We aim to (1) map relating behaviours between participants and their created avatars and (2) examine therapeutic actions delivered within AVATAR dialogue. METHOD: Twenty-five of the fifty-three AVATAR therapy completers were randomly selected from a randomized controlled trial (Craig et al. The Lancet Psychiatry, 5, 2018 and 31). Seventy-five audio recordings of active dialogue from sessions 1 and 4 and the last session were transcribed and analysed using a newly developed coding frame. Inter-rater reliability was good to excellent. RESULTS: Fine-grained analysis of 4,642 observations revealed nuanced communication around relational power and therapeutic activity. Early assertiveness work, reinforced by the therapist, focussed on increasing power and distancing. Participants’ submissive behaviours reduced during therapy, but the shift was gradual. Once the transition to a more conciliatory tone took place, the dialogue primarily involved direct communication between participant and avatar, focussing on sense of self and developmental and relational understanding of voices. CONCLUSIONS: AVATAR therapy supports voice-hearers in becoming more assertive towards a digital representation of their abusive voice. Direct dialogue with carefully characterized avatars aims to build the voice-hearers’ positive sense of self, supporting the person to make sense of their experiences. PRACTITIONER POINTS: AVATAR therapy enables voice-hearers to engage in face-to-face dialogue with a digital representation (‘avatar’) of their persecutory voice. Fine-grained analyses showed how relating behaviours and therapeutic actions evolve during active AVATAR therapy dialogue. Carefully characterized avatars and direct therapist input help voice-hearers become more assertive over the avatar, enhance positive sense of self, and support individuals to make sense of their experiences

Clinical and service implications of a cognitive analytic therapy model of psychosis

Cognitive analytic therapy (CAT) is an integrative, interpersonal model of therapy predicated on a radically social concept of self, developed over recent years in the UK by Anthony Ryle. A CAT-based model of psychotic disorder has been developed much more recently based on encouraging early experience in this area. The model describes and accounts for many psychotic experiences and symptoms in terms of distorted, amplified or muddled enactments of normal or ‘neurotic’ reciprocal role procedures (RRPs) and of damage at a meta-procedural level to the structures of the self. Reciprocal role procedures are understood in CAT to represent the outcome of the process of internalization of early, sign-mediated, interpersonal experience and to constitute the basis for all mental activity, normal or otherwise. Enactments of maladaptive RRPs generated by early interpersonal stress are seen in this model to constitute a form of ‘internal expressed emotion’. Joint description of these RRPs and their enactments (both internally and externally) and their subsequent revision is central to the practice of CAT during which they are mapped out through written and diagrammatic reformulations. This model may usefully complement and extend existing approaches, notably recent CBT-based interventions, particularly with ‘difficult’ patients, and generate meaningful and helpful understandings of these disorders for both patients and their treating teams. We suggest that use of a coherent and robust model such as CAT could have important clinical and service implications in terms of developing and researching models of these disorders as well as for the training of multidisciplinary teams in their effective treatment

Digitally supported CBT to reduce paranoia and improve reasoning for people with schizophrenia-spectrum psychosis: the SlowMo RCT

Background: Reasoning may play a causal role in paranoid delusions in psychosis. SlowMo, a new digitally supported cognitive–behavioural therapy, targets reasoning to reduce paranoia. Objectives: To examine the effectiveness of SlowMo therapy in reducing paranoia and in improving reasoning, quality of life and well-being, and to examine its mechanisms of action, moderators of effects and acceptability. Design: A parallel-arm, assessor-blind, randomised controlled trial comparing SlowMo plus treatment as usual with treatment as usual alone. An online independent system randomised eligible participants (1 : 1) using randomly varying permuted blocks, stratified by site and paranoia severity. Setting: Community mental health services in three NHS mental health trusts in England, plus patient identification centres. Participants: A total of 362 participants with schizophrenia-spectrum psychosis. Eligibility criteria comprised distressing and persistent (≥ 3 months) paranoia. Interventions: Eight face-to-face SlowMo sessions over 12 weeks plus treatment as usual, or treatment as usual alone (control group). Main outcome measures: The primary outcome measure was paranoia measured by the Green Paranoid Thoughts Scale and its revised version, together with observer-rated measures of persecutory delusions (The Psychotic Symptom Rating Scales delusion scale and delusion items from the Scale for the Assessment of Positive Symptoms). The secondary outcome measures were reasoning (measures of belief flexibility, jumping to conclusions, and fast and slow thinking), well-being, quality of life, schemas, service use and worry. Results: A total of 362 participants were recruited between 1 May 2017 and 14 May 2019: 181 in the SlowMo intervention group and 181 in the treatment-as-usual (control) group. One control participant subsequently withdrew. In total, 325 (90%) participants provided primary Green Paranoid Thoughts Scale outcome data at 12 weeks (SlowMo, n = 162; treatment as usual, n = 163). A total of 145 (80%) participants in the SlowMo group completed all eight therapy sessions. SlowMo was superior to treatment as usual in reducing paranoia on all three measures used: Green Paranoid Thoughts Scale total at 12 weeks (Cohen’s d = 0.30, 95% confidence interval 0.09 to 0.51; p = 0.005) and 24 weeks (Cohen’s d = 0.20, 95% confidence interval –0.02 to 0.40; p = 0.063); Psychotic Symptom Rating Scales delusions at 12 weeks (Cohen’s d = 0.47, 95% confidence interval 0.17 to 0.78; p = 0.002) and 24 weeks (Cohen’s d = 0.50, 95% confidence interval 0.20 to 0.80; p = 0.001); and Scale for the Assessment of Positive Symptoms persecutory delusions at 12 weeks (Cohen’s d = 0.43, 95% confidence interval 0.03 to 0.84; p = 0.035) and 24 weeks (Cohen’s d = 0.54, 95% confidence interval 0.14 to 0.94; p = 0.009). Reasoning (belief flexibility, possibility of being mistaken and Fast and Slow Thinking Questionnaire measure) improved, but jumping to conclusions did not improve. Worry, quality of life, well-being and self-concept also improved, improving most strongly at 24 weeks. Baseline characteristics did not moderate treatment effects. Changes in belief flexibility and worry mediated changes in paranoia. Peer researcher-led qualitative interviews confirmed positive experiences of the therapy and technology. Nineteen participants in the SlowMo group and 21 participants in the treatment-as-usual group reported 54 adverse events (51 serious events, no deaths). Limitations: The trial included treatment as usual as the comparator and, thus, the trial design did not control for the effects of time with a therapist. Conclusions To the best of our knowledge, this is the largest trial of a psychological therapy for paranoia in people with psychosis and the first trial using a brief targeted digitally supported therapy. High rates of therapy uptake demonstrated acceptability. It was effective for paranoia, comparable to longer therapy, and equally effective for people with different levels of negative symptoms and working memory. Mediators were improvements in belief flexibility and worry. Our results suggest that targeting reasoning helps paranoia. Future work: Further examination of SlowMo mechanisms of action and implementation

The role of characterisation in everyday voice engagement and AVATAR therapy dialogue

Background: Voices are commonly experienced as communication with a personified ‘other’ with ascribed attitudes, intentionality and personality (their own ‘character’). Phenomenological work exploring voice characterisation informs a new wave of relational therapies. To date, no study has investigated the role of characterisation in behavioural engagement with voices or within psychological therapy for distressing voices. Methods: Baseline characterisation (the degree to which the voice is an identifiable and characterful entity) of the dominant voice was rated (high, medium or low) using a newly developed coding framework, for n = 60 people prior to starting AVATAR therapy. Associations between degree of characterisation and (i) everyday behavioural engagement with voices (The Beliefs about Voices Questionnaire-Revised; n = 60); and (ii) interaction within avatar dialogue [Session 4 Time in Conversation (participant–avatar); n = 45 therapy completers] were explored. Results: Thirty-three per cent reported high voice characterisation, 42% medium and 25% low. There was a significant association between characterisation and behavioural engagement [H(2) = 7.65, p = 0.022, ɛ2 = 0.130] and duration of participant–avatar conversation [F(2,42) = 6.483, p = 0.004, η2 = 0.236]. High characterisation was associated with increased behavioural engagement compared with medium (p = 0.004, r = 0.34; moderate effect) and low (p = 0.027, r = 0.25; small−moderate effect) with a similar pattern observed for the avatar dialogue [high v. medium: p = 0.008, Hedges’ g = 1.02 (large effect); high v. low: p = 0.023, Hedges' g = 1.03 (large effect)]. No differences were observed between medium and low characterisation. Discussion: Complex voice characterisation is associated with how individuals interact with their voice(s) in and out of therapy. Clinical implications and future directions for AVATAR therapy and other relational therapies are discussed

Psychological characteristics of religious delusions

Purpose Religious delusions are common and are considered to be particularly difficult to treat. In this study we investigated what psychological processes may underlie the reported treatment resistance. In particular, we focused on the perceptual, cognitive, affective and behavioural mechanisms held to maintain delusions in cognitive models of psychosis, as these form the key treatment targets in cognitive behavioural therapy. We compared religious delusions to delusions with other content. Methods Comprehensive measures of symptoms and psychological processes were completed by 383 adult participants with delusions and a schizophrenia spectrum diagnosis, drawn from two large studies of cognitive behavioural therapy for psychosis. Results Binary logistic regression showed that religious delusions were associated with higher levels of grandiosity (OR 7.5; 95 % CI 3.9–14.1), passivity experiences, having internal evidence for their delusion (anomalous experiences or mood states), and being willing to consider alternatives to their delusion (95 % CI for ORs 1.1–8.6). Levels of negative symptoms were lower. No differences were found in delusional conviction, insight or attitudes towards treatment. Conclusions Levels of positive symptoms, particularly anomalous experiences and grandiosity, were high, and may contribute to symptom persistence. However, contrary to previous reports, we found no evidence that people with religious delusions would be less likely to engage in any form of help. Higher levels of flexibility may make them particularly amenable to cognitive behavioural approaches, but particular care should be taken to preserve self-esteem and valued aspects of beliefs and experiences

AbstractPurposeEvidence for the recommendation to deliver Cognitive Behavioural Therapy (CBT) and Family Interventions (FI) to under-18s with psychosis derives from adult research, and no previous study has focused exclusively on an adolescent population. We evaluated adaptations of these therapies for adolescent inpatients with psychosis (CBTpA and FIpA), delivered as an adjunct to inpatient standard care (SC).Subjects and methodsThirty adolescent inpatients with psychotic symptoms on admission were sequentially allocated to receive CBTpA + SC (n = 10); FIpA + SC (n = 10) or SC alone (n = 10). Psychotic symptoms and functioning were measured at admission and discharge.ResultsGroup comparisons did not reach conventional significance, but effect sizes in this pilot study showed a promising impact of CBTpA compared to SC alone, in reducing symptoms (ES: d = 0.6), with smaller effect sizes for functioning (d = 0.2) and for FIpA (symptoms, d = 0.1 and functioning, d = 0.4). There was no advantage of either additional treatment in reducing length of stay, but self-report satisfaction ratings were higher for both psychological therapies.Discussion and conclusionsThe study is the first to focus on an exclusively adolescent population, using appropriately adapted therapy protocols. Findings suggest that the interventions are feasible, acceptable and helpful for adolescents with psychosis. Larger randomised controlled trials are now needed.</jats:sec
