A systematic review of users experiences of using digital interventions within psychosis: a thematic synthesis of qualitative research.

PURPOSE: Although the development of digital mental health support for people with psychosis has been increasing, the development and opportunities to access this have been more limited compared to other mental health conditions. Qualitative research exploring the experiences of using digital interventions amongst people with psychosis is even less well developed; however, such research is crucial in capturing the experiences of using digital interventions to ensure they are meeting the needs of people with psychosis. This paper aimed to synthesise qualitative data related to the experiences of people with psychosis who have used digital interventions. METHODS: A systematic literature search was conducted of articles published between 1992 and October 2023 using PubMed, MBase, PsycINFO, & OVID Medline. Two reviewers independently reviewed and screened 268 papers. Papers that met inclusion criteria were quality assessed using The Critical Appraisal Skills Programme (CASP) qualitative studies checklist. The Enhancing Transparency in Reporting the Synthesis of Qualitative Research (ENTREQ) checklist was used to guide the structure of the report. RESULTS: A thematic synthesis of 19 studies revealed six overarching themes which related to different aspects and features of the digital interventions: participants' relationship with technology; the accessibility of the interventions; how the interventions could impact on individuals' awareness and management of mental health; enhanced communication and relationships; and opportunities for reflection. CONCLUSIONS: Benefits of using digital interventions are discussed. Areas for development and improvements are highlighted. Finally, recommendations for stakeholders who develop and implement digital interventions for psychosis are made.

Participants' experiences of AVATAR therapy for distressing voices: a thematic qualitative evaluation.

BACKGROUND: AVATAR therapy is an innovative therapy designed to support people with distressing voices. Voice hearers co-create a digital representation of their voice and engage in dialogue with it. Although it has been successfully tested in a powered randomised controlled trial (ISRCTN65314790), the participants' experience of this therapy has not been yet evaluated. We aimed to explore enablers and barriers to engagement with the therapy and potential for real-world impact on distressing voices. METHODS: Thirty per cent of those who completed AVATAR therapy (15 people in total) and 5 who dropped out from therapy within the main AVATAR RCT were invited to participate in a semi-structured interview, which was audio-recorded and subsequently transcribed. RESULTS: Fourteen therapy completers (28% of the full sample) and one person who dropped out of therapy after 1 active session, were interviewed. Thematic analysis was used to explore the interviews. A total of 1276 references were coded, and five overarching themes identified: AVATAR therapy set-up; voice embodiment and associated emotions; working in a safe space (supported by the therapist); learning new ways of relating to the voices; impact of therapy on everyday life. Overall, the therapy set-up, with its digital components and its distinctive features as compared with common face-to-face talking therapies, was satisfactory. The inclusion of technology was well accepted as both a means to deliver the therapy and a tool to create a digital representation of the person's distressing voice. The co-creation of the avatar and the enactment of the relationship between the person and the voice were perceived as a very helpful process to promote the therapeutical dialogue. Participants reported engaging well with the therapist and feeling supported and identified specific learnt strategies to deal with the voices and how they have had an impact on everyday life. CONCLUSIONS: AVATAR therapy is acceptable and provides benefit for participants with psychosis. Our results highlighted the enablers and challenges of working dialogically with distressing voices using a digital representation and dealing with highly demanding emotional, cognitive, and relational processes linked to the experience. Our analysis also identified the core strategies learnt by participants and how these were generalised to their daily life resulting into a positive change in different domains, and in particular broader social relationships.

The impact of Patient and Public Involvement in the SlowMo study: Reflections on peer innovation.

BACKGROUND: The SlowMo study demonstrated the effects of SlowMo, an eight-session digitally supported reasoning intervention, on paranoia in a large-scale randomized-controlled trial with 362 participants with schizophrenia-spectrum psychosis. AIM: The current evaluation aimed to investigate the impact of Patient and Public Involvement (PPI) in the SlowMo study. METHOD: PPI members were six women and three men from Sussex, Oxford and London with experience of using mental health services for psychosis. They received training and met at least 3-monthly throughout the project. The impact of PPI was captured quantitatively and qualitatively through (i) a PPI log of recommendations and implementation; (ii) written subjective experiences of PPI members; (iii) meeting minutes; and (iv) outputs produced. RESULTS: The PPI log revealed 107 recommendations arising from PPI meetings, of which 87 (81%) were implemented. Implementation was greater for recruitment-, data collection- and organization-related actions than for dissemination and emergent innovations. Qualitative feedback revealed impacts on study recruitment, data collection, PPI participants' confidence, knowledge, career aspirations and society more widely. Outputs produced included a film about psychosis that aired on BBC primetime television, novel webpages and journal articles. Barriers to PPI impact included geography, travel, funding, co-ordination and well-being. DISCUSSION: A future challenge for PPI impact will be the extent to which peer innovation (innovative PPI-led ideas) can be supported within research study delivery. PATIENT AND PUBLIC CONTRIBUTION: Planned Patient and Public Contribution in SlowMo comprised consultation and collaboration in (i) design, (ii) recruitment, (iii) qualitative interviews and analysis of service users' experiences of SlowMo therapy and (iv) dissemination.

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.

Need for care, adversity exposure and perceived stress in clinical and healthy voice-hearers.

OBJECTIVES: Psychosis, and in particular auditory verbal hallucinations (AVHs), are associated with adversity exposure. However, AVHs also occur in populations with no need for care or distress. AIMS: This study investigated whether adversity exposure would differentiate clinical and healthy voice-hearers within the context of a 'three-hit' model of vulnerability and stress exposure. METHODS: Samples of 57 clinical and 45 healthy voice-hearers were compared on the three 'hits': familial risk; adversity exposure in childhood and in adolescence/adulthood. RESULTS: Clinical voice-hearers showed greater familial risk than healthy voice-hearers, with more family members with a history of psychosis, but not with other mental disorders. The two groups did not differ in their exposure to adversity in childhood [sexual and non-sexual, victimisation; discrimination and socio-economic status (SES)]. Contrary to expectations, clinical voice-hearers did not differ from healthy voice-hearers in their exposure to victimisation (sexual/non-sexual) and discrimination in adolescence/adulthood, but reported more cannabis and substance misuse, and lower SES. CONCLUSIONS: The current study found no evidence that clinical and healthy voice-hearers differ in lifetime victimisation exposure, suggesting victimisation may be linked to the emergence of AVHs generally, rather than need-for-care. Familial risk, substance misuse and lower SES may be additional risk factors involved in the emergence of need-for-care and distress.

Elucidating negative symptoms in the daily life of individuals in the early stages of psychosis.

BACKGROUND: It remains poorly understood how negative symptoms are experienced in the daily lives of individuals in the early stages of psychosis. We aimed to investigate whether altered affective experience, anhedonia, social anhedonia, and asociality were more pronounced in individuals with an at-risk mental state for psychosis (ARMS) and individuals with first-episode psychosis (FEP) than in controls. METHODS: We used the experience sampling methodology (ESM) to assess negative symptoms, as they occurred in the daily life of 51 individuals with FEP and 46 ARMS, compared with 53 controls. RESULTS: Multilevel linear regression analyses showed no overall evidence for a blunting of affective experience. There was some evidence for anhedonia in FEP but not in ARMS, as shown by a smaller increase of positive affect (BΔat-risk v. FEP = 0.08, p = 0.006) as the pleasantness of activities increased. Against our expectations, no evidence was found for greater social anhedonia in any group. FEP were more often alone (57%) than ARMS (38%) and controls (35%) but appraisals of the social situation did not point to asociality. CONCLUSIONS: Overall, altered affective experience, anhedonia, social anhedonia and asociality seem to play less of a role in the daily life of individuals in the early stages of psychosis than previously assumed. With the experience of affect and pleasure in daily life being largely intact, changing social situations and appraisals thereof should be further investigated to prevent development or deterioration of negative symptoms.

Virtual reality-based assessment and treatment of social functioning impairments in psychosis: a systematic review.

People with psychosis can experience social functioning impairments. Virtual reality (VR) has been used to assess and treat these difficulties. This systematic review (Prospero CRD42015026288) provides an evaluation of these VR applications. PsycINFO, MEDLINE, Embase, Web of Science, Cochrane Library, and Scopus were searched until May 2020. The Effective Public Health Practice Project (EPHPP) Quality Assessment Tool was used to assess studies. Database searching identified 3810 titles. Fifty-eight studies (published 2005-2020; N = 2,853), comprising twenty-six head-mounted display studies (20 assessment, 6 treatment) and thirty-two immersive 2D screen studies (23 assessment, 9 treatment), were included. There were forty-eight observational studies and ten randomised controlled trials, with 1570 participants (of which, 185 were at ultra-high risk of psychosis) in VR test groups. Nearly half the studies were published since 2016. Assessments targeted cognitive and behavioural indicators of social functioning, e.g. paranoia, eye gaze, or interpersonal distance. Treatments promoted cognitive-behavioural social skills or job interview training. Studies indicate feasibility, acceptability, and effectiveness of VR for social functioning impairments in psychosis. Limitations of studies include the narrow scope of social functioning, small sample sizes, and limited randomised controlled trials and standardised interventions. Findings suggest VR has potential to be integrated with existing psychological approaches.

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 theoretical relevance of responses to analogues of psychotic experiences in people with psychotic experiences with and without a need-for-care: an experimental study.

BACKGROUND: Certain ways of responding to psychotic experiences (PEs) appear more commonly associated with clinical distress (e.g. avoidance) and other ways with benign or positive outcomes (e.g. reappraisal and acceptance). Past research has largely been limited to retrospective self-report. We aimed to compare clinical and non-clinical individuals on experimental analogues of anomalous experiences. METHOD: Response styles of two groups with persistent PEs (clinical n = 84; non-clinical n = 92) and a control group without PEs (n = 83) were compared following experimental analogues of thought interference (Cards Task, Telepath) and hearing voices (Virtual Acoustic Space Paradigm). RESULTS: The non-clinical group with PEs were less likely to endorse unhelpful response styles, such as passive responding or attempts to avoid, suppress, worry about or control mental experiences, compared with the clinical group on all three tasks. The clinical group were more likely to endorse unhelpful response styles compared with controls on two out of three tasks (Cards Task and Telepath). The non-clinical group performed similarly to controls on unhelpful responding across all tasks. There were no group differences for helpful response styles, such as cognitive reappraisal or mindful acceptance of experiences. CONCLUSIONS: In line with cognitive models of psychosis, the findings suggest that the way in which individuals respond to unusual experiences may be an important factor in understanding clinical distress, supporting the therapeutic rationale of targeting potentially unhelpful patterns of response.

Subjective experience of paranoid ideation in a virtual reality social environment: A mixed methods cross-sectional study.

Virtual reality-assisted cognitive-behavioural therapy (VR-CBT) has potential to support people who experience paranoid ideation in social settings. However, virtual reality (VR) research using overt social environments is limited, and lack of qualitative studies on paranoid ideation in VR restricts understanding. This study aimed to use predominantly qualitative methods to investigate subjective experience of paranoia in VR and identify target domains for VR-CBT. Participants (N = 36) were non-clinical adults with high trait paranoia, who entered an interactive VR bar-room environment. After VR, they participated in brief audiotaped semi-structured interviews designed for measuring persecutory ideation in virtual environments. Researchers scored transcripts on the Comprehensive Assessment of At-Risk Mental States Non-Bizarre Ideas Global Rating Scale to rate the state paranoia represented by interview content. Thematic analysis of interviews employed superordinate themes of Social Evaluative Concerns, Ideas of Reference, and Ideas of Persecution to investigate participants' experience of paranoia. Mean score on the Non-Bizarre Ideas scale was 3.06 (standard deviation 1.24, range 1-6), indicating "moderate" attenuated-paranoid experiences. Nearly all participants reported Social Evaluative Concerns (N = 35) and Ideas of Reference (N = 32); half reported Ideas of Persecution (N = 19). Twelve subthemes were identified. Notably, participants believed they did not belong in the environment (N = 31), that they were the object of discussion (N = 20), and that they felt avatars were unfriendly (N = 27) and intentionally rejected them (N = 13). Subthemes reflect interpersonal and social processes that may constitute target areas for VR-CBT, for example, cognitive appraisals and social skills. Identification of these domains indicates how personalized VR-CBT may be operationalized.

The relationship between depressive symptoms and negative symptoms in people with non-affective psychosis: a meta-analysis.

The negative symptoms of psychosis and depressive symptomatology share several features, e.g. low motivation, apathy and reduced activity. Understanding the associations between these two sets of symptoms will support improved assessment and the development of interventions targeting these difficulties in people with psychosis. This is the first large systematic review and meta-analysis to quantify the relationship between these two categories of symptoms, as measured in studies to date. PsycInfo, Embase and Medline were systematically searched to identify eligible studies. Inclusion criteria ensured the studies measured both depression and negative symptoms using validated measures in a sample of over 8000 participants with non-affective psychosis diagnoses. The search led to 2020 records being screened and 56 included in the meta-analysis and review. Both meta-analyses and meta-regressions were conducted to explore the main effect and potential moderating variables. A clear pattern emerges showing that higher ratings of negative symptoms are associated with higher levels of depressive symptoms, with a small effect [standardised effect size = 0.19, p < 0.05). This did not vary greatly with the measures used (SES = 0.19-0.26) and was not moderated by demographic variables or quality ratings. Interestingly, higher depressive symptoms predict a significant relationship with co-occurring negative symptoms. However, higher negative symptoms predict that it is less likely there will be a relationship with co-occurring depressive symptoms. Heterogeneity was high across these analyses. The findings support the adoption of a symptom-specific approach to understanding the interplay between negative and depressive symptoms in psychosis, to improve assessment and intervention.

Overgeneral autobiographical memory bias in clinical and non-clinical voice hearers.

BACKGROUND: Hearing voices can be a distressing and disabling experience for some, whilst it is a valued experience for others, so-called 'healthy voice-hearers'. Cognitive models of psychosis highlight the role of memory, appraisal and cognitive biases in determining emotional and behavioural responses to voices. A memory bias potentially associated with distressing voices is the overgeneral memory bias (OGM), namely the tendency to recall a summary of events rather than specific occasions. It may limit access to autobiographical information that could be helpful in re-appraising distressing experiences, including voices. METHODS: We investigated the possible links between OGM and distressing voices in psychosis by comparing three groups: (1) clinical voice-hearers (N = 39), (2) non-clinical voice-hearers (N = 35) and (3) controls without voices (N = 77) on a standard version of the autobiographical memory test (AMT). Clinical and non-clinical voice-hearers also completed a newly adapted version of the task, designed to assess voices-related memories (vAMT). RESULTS: As hypothesised, the clinical group displayed an OGM bias by retrieving fewer specific autobiographical memories on the AMT compared with both the non-clinical and control groups, who did not differ from each other. The clinical group also showed an OGM bias in recall of voice-related memories on the vAMT, compared with the non-clinical group. CONCLUSIONS: Clinical voice-hearers display an OGM bias when compared with non-clinical voice-hearers on both general and voices-specific recall tasks. These findings have implications for the refinement and targeting of psychological interventions for psychosis.

Interpersonal processes in paranoia: a systematic review.

Paranoid ideation is a core feature of psychosis, and models of paranoia have long proposed that it arises in the context of disturbances in the perception of the self. However, to develop targeted interventions, there is a benefit in clarifying further, which aspects of self-perception are implicated. Interpersonal sensitivity is a personality trait which has been associated with the risk of paranoid thinking in the general population. However, not all studies have found this link. We aimed to review the empirical literature assessing the association between interpersonal sensitivity and paranoia in both general population and clinical samples; and to explore if associations found differed depending on whether state or trait paranoia was assessed. The review followed PRISMA guidelines. Articles were identified through a literature search in OVID (PsychINFO, MEDLINE) and Web of Science up to December 2016. Fourteen studies with a total of 12 138 participants were included. All studies were of 'fair' or 'good' quality. A robust association was found between interpersonal sensitivity and paranoia in clinical and general population samples alike, regardless of the method of assessment of both paranoia and interpersonal sensitivity. Although this finding was more pronounced in studies of trait paranoia, it is likely that differences in study purpose, measurement, and power explain these differences. Findings from this review support the hypothesis that feelings of personal vulnerability and exaggerated socially evaluative concerns are central for both onset and maintenance of paranoid symptoms, suggesting avenues for future research in targeted interventions.

Moment-to-moment associations between negative affect, aberrant salience, and paranoia.

INTRODUCTION: There is an ongoing debate about whether negative affect are consequences or triggers of paranoid thinking. It has also been suggested that aberrant salience is central to the development of delusions. This study modelled the moment-to-moment relationships between negative affect, aberrant salience, and paranoia in acute inpatients with psychosis. METHODS: Participants with active paranoid delusions were assessed using clinical rating scales and experience sampling method (ESM) over 14 days. ESM data were analysed using time-lagged multilevel regression modelling. RESULTS: Both negative affect and aberrant salience predicted an increase in paranoia at the next time point. Conversely, the level of paranoia did not predict subsequent changes in negative affect or aberrant salience. Negative affect predicted an increase in aberrant salience at the next time point, and vice versa. CONCLUSIONS: Negative affect and aberrant salience appear to drive and exacerbate paranoia, rather than being merely the sequelae of the symptom. Our results suggest both direct and indirect (via aberrant salience) pathways from negative affect to paranoia.

Experiences of outcome monitoring in service users with psychosis: Findings from an Improving Access to Psychological Therapies for people with Severe Mental Illness (IAPT-SMI) demonstration site.

OBJECTIVES: Psychological therapy services are increasingly required to instate routine outcome monitoring (ROM), to demonstrate the clinical and economic impact of interventions. Professionals' views of ROM are an acknowledged barrier to implementation. Service user perspectives have rarely been examined, but acceptability and perceptions of ROM are critical to successful implementation. We investigated service users' experiences of ROM in an Improving Access to Psychological Therapies for people with Severe Mental Illness psychosis demonstration site. DESIGN: ROM comprised a periodic assessment battery completed at baseline, mid-therapy, and end-of-therapy and a single measure completed session-by-session. Qualitative and quantitative feedback were sought at each periodic ROM administration, and, for sessional ROM, at mid-therapy and end-of-therapy. Demographic and clinical correlates of satisfaction were examined cross-sectionally at baseline. Consistency of satisfaction over time and associations of satisfaction with engagement were examined longitudinally. METHODS: Service users rated baseline (n = 281/289), mid-therapy (n = 114/121), end-of-therapy (n = 124/154), and session-by-session (mid-therapy n = 63/87 and end-of-therapy n = 90/123) ROM from 0 ('extremely unhelpful') to 10 ('extremely helpful') and gave qualitative feedback. RESULTS: Service users predominantly found ROM helpful (score 6-10; 64-72%) or neutral (score 5; 19-29%). Finding ROM less helpful was associated with younger age and poorer general outcomes, but not with psychotic symptoms or therapy dropout. Emerging qualitative themes included feeling understood, valuing opportunities to reflect, expressing feelings, and tracking progress towards goals. Shorter batteries would be preferable, particularly for younger respondents, and those with poorer outcomes. CONCLUSIONS: ROM is acceptable for people with psychosis. Tailoring assessments to specific subgroups should be considered. PRACTITIONER POINTS: Routine outcome monitoring for psychological therapy is acceptable to people with psychosis. Most respondents experienced outcome monitoring as an opportunity to feel understood. Younger people and those with poorer functioning and well-being might be at higher risk of dissatisfaction. Short assessment batteries and less frequent outcome monitoring might be preferable for some service users. Limitations of the study Feedback about session-by-session outcome monitoring was not contemporaneous with completion and may be subject to memory or other biases. Only two-thirds of service users provided feedback about session-by-session ROM (compared to >94% for periodic ROM) so findings may not be fully representative. Feedback about measures was not provided anonymously, and it is possible that service users were reluctant to express criticism about ROM to the assessor.

Targeting Recovery in Persistent Persecutory Delusions: A Proof of Principle Study of a New Translational Psychological Treatment (the Feeling Safe Programme).

BACKGROUND: Many patients do not respond adequately to current pharmacological or psychological treatments for psychosis. Persistent persecutory delusions are common in clinical services, and cause considerable patient distress and impairment. Our aim has been to build a new translational personalized treatment, with the potential for wide use, that leads to high rates of recovery in persistent persecutory delusions. We have been developing, and evaluating individually, brief modular interventions, each targeting a key causal factor identified from our cognitive model. These modules are now combined in "The Feeling Safe Programme". AIMS: To test the feasibility of a new translational modular treatment for persistent persecutory delusions and provide initial efficacy data. METHOD: 12 patients with persistent persecutory delusions in the context of non-affective psychosis were offered the 6-month Feeling Safe Programme. After assessment, patients chose from a personalized menu of treatment options. Four weekly baseline assessments were carried out, followed by monthly assessments. Recovery in the delusion was defined as conviction falling below 50% (greater doubt than certainty). RESULTS: 11 patients completed the intervention. One patient withdrew before the first monthly assessment due to physical health problems. An average of 20 sessions (SD = 4.4) were received. Posttreatment, 7 out of 11 (64%) patients had recovery in their persistent delusions. Satisfaction ratings were high. CONCLUSIONS: The Feeling Safe Programme is feasible to use and was associated with large clinical benefits. To our knowledge this is the first treatment report focused on delusion recovery. The treatment will be tested in a randomized controlled trial.

A pilot evaluation of therapist training in cognitive therapy for psychosis: therapy quality and clinical outcomes.

BACKGROUND: Historically, it has been difficult to demonstrate an impact of training in psychological interventions for people with psychosis on routine practice and on patient outcomes. A recent pilot evaluation suggested that postgraduate training in Cognitive Behavioural Therapy for Psychosis (CBTp) increased the delivery of competent therapy in routine services. In this study, we evaluated clinical outcomes for patients receiving therapy from therapists who successfully completed training, and their association with ratings of therapist competence and therapy content. AIMS: To characterize the therapy delivered during training and to inform both a calculation of effect size for its clinical impact, and the development of competence benchmarks to ensure that training standards are sufficient to deliver clinical improvement. METHOD: Paired patient-reported outcome measures (PROMS) were extracted from anonymized therapy case reports, and were matched with therapy ratings for each therapist. RESULTS: Twenty clients received a course of competent therapy, including a high frequency of active therapy techniques, from nine therapists. Pre-post effect size for change in psychotic symptoms was large (d = 1.0) and for affect, medium (d = 0.6), but improved outcomes were not associated with therapist competence or therapy content. CONCLUSIONS: Therapists trained to research trial standards of competence achieved excellent clinical outcomes. Therapy effect sizes suggest that training costs may be offset by clinical benefit. Larger, methodologically stringent evaluations of training are now required. Future research should assess the necessary and sufficient training required to achieve real-world clinical effectiveness, and the cost-effectiveness of training.

Training frontline mental health staff to deliver "low intensity" psychological therapy for psychosis: a qualitative analysis of therapist and service user views on the therapy and its future implementation.

BACKGROUND: Increasing access to evidence-based talking therapies for people with psychosis is a national health priority. We have piloted a new, "low intensity" (LI) CBT intervention specifically designed to be delivered by frontline mental health staff, following brief training, and with ongoing supervision and support. A pilot feasibility study has demonstrated significant improvement in service user outcomes. This study is a qualitative analysis of the experiences of the staff and service users taking part in the evaluation. AIMS: To evaluate the acceptability of the training protocol and the therapy, and to examine the factors promoting and restraining implementation. METHOD: All trained staff and service users completed a semi-structured interview that was transcribed and subjected to thematic analysis. RESULTS: Service users spoke about learning new skills and achieving their goals. Staff spoke about being able to use a brief, structured intervention to achieve positive outcomes for their clients. Both groups felt that longer, more sophisticated interventions were required to address more complex problems. The positive clinical outcomes motivated therapists to continue using the approach, despite organizational barriers. CONCLUSIONS: For both trained staff and service users, taking part in the study was a positive experience. Staff members' perceived skill development and positive reaction to seeing their clients improve should help to promote implementation. Work is needed to clarify whether and how more complex difficulties should be addressed by frontline staff.

Urbanicity, persecutory delusions, and clinical intervention: the development of a brief CBT module for helping patients with persecutory delusions enter social urban environments.

BACKGROUND: Substantial epidemiological research has shown that psychotic experiences are more common in densely populated areas. Many patients with persecutory delusions find it difficult to enter busy social urban settings. The stress and anxiety caused by being outside lead many patients to remain in-doors. We therefore developed a brief CBT intervention, based upon a formulation of the way urban environments cause stress and anxiety, to help patients with paranoid thoughts to feel less distressed when outside in busy streets. AIMS: The aim was to pilot the new intervention for feasibility and acceptability and gather preliminary outcome data. METHOD: Fifteen patients with persecutory delusions in the context of a schizophrenia diagnosis took part. All patients first went outside to test their reactions, received the intervention, and then went outside again. RESULTS: The intervention was considered useful by the patients. There was evidence that going outside after the intervention led to less paranoid responses than the initial exposure, but this was only statistically significant for levels of distress. CONCLUSIONS: Initial evidence was obtained that a brief CBT module specifically focused on helping patients with paranoia go outside is feasible, acceptable, and may have clinical benefits. However, it could not be determined from this small feasibility study that any observed improvements were due to the CBT intervention. Challenges in this area and future work required are outlined.
