Multisite randomised controlled trial of a novel dialogical therapy in comparison to treatment as usual in adults with distressing and persistent auditory hallucinations: study protocol for the Talking With Voices (TWV-II) trial.
Article in Trials, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHearing voices ("auditory hallucinations") is associated with numerous negative outcomes, including hospitalisation, suicidality, and impaired functioning. Currently, the main treatment approaches are antipsychotic medication and cognitive behavioural therapy (CBT), yet both have variable effectiveness and are often unavailable to those without a schizophrenia diagnosis. Furthermore, CBT does not consistently address the role of trauma in voice onset and maintenance. In response to these unmet needs, a feasibility/acceptability trial of a new intervention, Talking With Voices (TWV), was conducted. TWV involves a therapist speaking to the voice(s) while the client repeats its response verbatim, with the aim of promoting recovery and reducing voice-related distress. This prior pilot study (N = 50) found excellent feasibility/acceptability data amongst participants with schizophrenia, and signals of positive change in measures of personal recovery and voice relating. The next step is to evaluate treatment mechanisms and clinical efficacy of TWV in a transdiagnostic population.
methodsWe aim to establish TWV's clinical efficacy in a multisite RCT for adults with serious mental health problems (SMHP) who hear persistent, distressing voices, and to assess whether improved measures of personal recovery and negative voice impact are mediated via key psychological mechanisms (improved relating to, and beliefs about, voices; and reductions in dissociation and negative self-beliefs). We aim to recruit 296 participants from psychiatric services across 4 UK sites (Manchester, London, Newcastle, and Oxford) who will be randomised to either treatment (TWV + treatment as usual [TAU]) or control (TAU only). The primary outcome is total score on the Questionnaire About the Process of Recovery. Secondary outcomes include overall voice severity and other relevant dimensions of voices and trauma sequalae, with mediational and outcome variables collected at baseline, 8 months (post-treatment), and 14 months. DISCUSSION: The study will investigate the clinical efficacy of a novel intervention deliverable within healthcare services, including hypothesised mechanisms of change to identify key psychological targets for ameliorating distressing voices in a transdiagnostic population. Potential benefits include improving the effectiveness and accessibility of evidence-based psychosocial interventions for SMHP.
