    The main purpose of the present study is to investigate the capacity of schizotypy and alexithymia traits, in combination with affectivity to predict facial emotion recognition capability in a sample of nonclinical adults. Consecutive healthy participants (N= 98) were investigated using the Toronto Alexithymia Scale-20 (TAS-20), the Oxford-Liverpool Inventory of Feelings and Experiences-Reduced Version (O-LIFE-R), and the Positive and NA Schedule (PANAS). A set of validated photographs (static images) and virtual faces (dynamic images) for presenting the basic emotions was used to assess emotion recognition. Pearson correlations were applied to investigate the relationship between the study variables; the amount of variance in emotion recognition capability predicted by OLIFE-R, TAS-20 and PANAS was calculated by using the linear regression model. Results showed that alexithymia was strongly associated with schizotypy and NA; furthermore, alexithymia and NA made a significant contribution to the prediction of emotion recognition capability. The predictive model was fitted for two types of presentations (photographs and virtual reality). The inclusion of virtual faces emerges as a response to the need to consider computer characters as new assessment and treatment material for research and therapy in psychologyEl objetivo principal del presente estudio es investigar la capacidad de predicción de los rasgos de esquizotípia y alexitímia, en combinación con la afectividad, de la habilidad de reconocimiento de emociones en una muestra de adultos sanos. Noventa y ocho pacientes sanos (N =98) fueron evaluados mediante la Escala de Alexitímia Toronto-20 (TAS-20), el Inventario de Sentimientos y Experiencias Oxford-Liverpool-Versión Reducida (O-LIFE-R), y la Escala de Afecto Positivo y Negativo (PANAS). Para la evaluación de la capacidad de reconocimiento de emociones a nivel facial, se utilizó un set validado de fotografías (imágenes estáticas) y caras en realidad virtual (imágenes dinámicas). Para el análisis correlacional de las variables de estudio se aplicó la prueba de correlación de Pearson; para el análisis de predicción de la capacidad de reconocimiento emocional se utilizó un modelo de regresión lineal en el que se incluyeron las variables derivadas de las escalas OLIFE-R, TAS-20 y PANAS. Los resultados mostraron la existencia de una relación significativa entre alexitímia, esquizotípia y afecto negativo; el modelo de regresión reveló una aportación significativa de la alexitímia y el afecto negativo en la predicción de los errores cometidos en la tarea de reconocimiento facial. El modelo predictivo propuesto fue válido para ambos tipos de presentación de las emociones (fotografías y caras virtuales). La inclusión de las caras virtuales surge como respuesta a la necesidad de considerar los personajes computarizados como nuevo material de evaluación y tratamiento para la investigación y psicoterapia en psicología

    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

    IMPORTANCE: Persistent paranoia is common among patients with psychosis. Cognitive-behavioral therapy for psychosis can be effective. However, challenges in engagement and effectiveness remain. OBJECTIVE: To investigate the effects on paranoia and mechanisms of action of SlowMo, a digitally supported reasoning intervention, plus usual care compared with usual care only. DESIGN, SETTING, AND PARTICIPANTS: This parallel-arm, assessor-blinded, randomized clinical trial recruited participants at UK community health services from May 1, 2017, to May 14, 2019. Eligible participants consisted of a referral sample with schizophrenia-spectrum psychosis and distressing, persistent (≥3 months) paranoia. INTERVENTIONS: Individuals were randomized 1:1 to SlowMo, consisting of 8 digitally supported face-to-face sessions and a mobile app, plus usual care (n = 181) and usual care only (n = 181). MAIN OUTCOMES AND MEASURES: The primary outcome was paranoia, measured by the Green et al Paranoid Thoughts Scale (GPTS) total score at 24 weeks. Secondary outcomes included GPTS total score at 12 weeks and GPTS Part A (reference) and Part B (persecutory) scores, the Psychotic Symptom Rating Scales (PSYRATS Delusion subscale), reasoning (belief flexibility, possibility of being mistaken [Maudsley Assessment of Delusions, rated 0%-100%]), and jumping to conclusions (Beads Task). RESULTS: A total of 361 participants were included in intention-to-treat analysis, of whom 252 (69.8%) were male and 249 (69.0%) were White; the mean (SD) age was 42.6 (11.6) years. At 24 weeks, 332 participants (92.0%) provided primary outcome data. Of 181 participants in the SlowMo group, 145 (80.1%) completed therapy. SlowMo plus usual care was not associated with greater reductions than usual care in GPTS total score at 24 weeks (Cohen d, 0.20; 95% CI, −0.02 to 0.40; P = .06). There were significant effects on secondary paranoia outcomes at 12 weeks, including GPTS total score (Cohen d, 0.30; 95% CI, 0.09-0.51; P = .005), Part A score (Cohen d, 0.22; 95% CI, 0.06-0.39; P = .009), and Part B score (Cohen d, 0.32; 95% CI, 0.08-0.56; P = .009), and at 24 weeks, including Part B score (Cohen d, 0.25; 95% CI, 0.01-0.49; P = .04) but not Part A score (Cohen d, 0.12; 95% CI, −0.05 to 0.28; P = .18). Improvements were observed in an observer-rated measure of persecutory delusions (PSYRATS delusion) at 12 weeks (Cohen d, 0.47; 95% CI, 0.17-0.78; P = .002) and 24 weeks (Cohen d, 0.50; 95% CI, 0.20-0.80; P = .001) and belief flexibility at 12 weeks (Cohen d, 0.29; 95% CI, 0.09-0.49; P = .004) and 24 weeks (Cohen d, 0.28; 95% CI, 0.08-0.49; P = .005). There were no significant effects on jumping to conclusions. Improved belief flexibility and worry mediated paranoia change (range mediated, 36%-56%). CONCLUSIONS AND RELEVANCE: SlowMo did not demonstrate significant improvements in the primary measure of paranoia at 24 weeks; however, a beneficial effect of SlowMo on paranoia was indicated by the results on the primary measure at an earlier point and on observer-rated paranoia and self-reported persecution at 12 and 24 weeks. Further work to optimize SlowMo’s effects is warranted. TRIAL REGISTRATION: isrctn.org Identifier: ISRCTN 3244867

    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

    SlowMo, a digital therapy targeting reasoning in paranoia, versus treatment as usual in the treatment of people who fear harm from others: study protocol for a randomised controlled trial

    Background: Paranoia is one of the most common symptoms of schizophrenia-spectrum disorders, and is associated with significant distress and disruption to the person’s life. Developing more effective and accessible psychological interventions for paranoia is a clinical priority. Our research team has approached this challenge in two main ways: firstly, by adopting an interventionist causal approach to increase effectiveness and secondly, by incorporating user-centred inclusive design methods to enhance accessibility and usability. Our resultant new digital intervention, SlowMo, intensively targets a reasoning style associated with paranoia, fast thinking, characterised by jumping to conclusions and belief inflexibility. It consists of an easy-to-use, enjoyable and memorable digital interface. An interactive web-based app facilitates delivery of face-to-face meetings which is then synchronised with an innovative mobile app for use in daily life. Methods/Design: We aim to test the clinical efficacy of SlowMo over 24 weeks to determine the mechanisms through which it reduces paranoia, and to identify participant characteristics that moderate its effectiveness. In a parallel-group randomised controlled trial, with 1:1 allocation, 360 participants with distressing persecutory beliefs will be independently randomised to receive either the SlowMo intervention added to treatment as usual (TAU) or TAU, using randomly varying permuted blocks, stratified by paranoia severity and site. Research workers will be blind to therapy allocation. The primary outcome is paranoia severity over 24 weeks; our hypothesised mechanism of change is reasoning; moderators include negative symptoms and working memory; and secondary outcomes include wellbeing, quality of life, and service use. The accessibility, usability and acceptability of the digital platform will be assessed. Discussion: SlowMo has been developed as the first blended digital therapy to target fears of harm from others through an inclusive design approach. In addition to testing its efficacy, this trial will add to our understanding of psychological mechanisms in paranoia. The study will examine the usability and adherence of a novel digital therapy, including an app for self-management, in a large sample of people affected by severe mental health difficulties

    Purpose In the last decade researchers have embraced virtual reality to explore the psychological processes and mechanisms that are involved in the onset and maintenance of psychosis. A systematic review was conducted to synthesise the evidence of using virtual reality to investigate these mechanisms. Methods Web of Science, PsycINFO, Embase, and Medline were searched. Reference lists of collected paperswere also visually inspected to locate any relevant cited journal articles. In total 6001 articles were potentially eligible for inclusion; of these, 16 studies were included in the review. Results The review identified studies investigating the effect of interpersonal sensitivity, childhood bullying victimisation, physical assault, perceived ethnic discrimination, social defeat, population density and ethnic density on the real-time appraisal of VR social situations. Further studies demonstrated the potential of VR to investigate paranoid ideation, anomalous experiences, self-confidence, self-comparison, physiological activation and behavioural response. Conclusions The reviewed studies suggest that VR can be used to investigate psychological processes and mechanisms associated with psychosis. Implications for further experimental research, as well as for assessment and clinical practise are discussed. The present review has been registered in the PROSPERO register: CRD42016038085.</p

However, their implementation in the clinical setting as well as in treatment protocols of patients with psychosis has not been fully achieved yet. With the increasing deinstitutionalization of patients, family has begun to assume the role of care performed by psychiatric hospitals, with a high emotional cost for caregivers as well as the recognition of burden experiences. Families have been the substitute in the face of the scarcity of therapeutic, occupational, and residential resources. For this reason, the viability of patients&rsquo; care by their families has become a challenge. This article aims to discuss the most important aspects of family interventions, their impact on families, and the most important challenges that need to be overcome in order to achieve well-being and recovery in both patients and caregivers.
