Background: In people who experience auditory verbal hallucinations, beliefs the person holds about their voices appear to be clinically important as mediators of associated distress and disability. Whilst such beliefs are thought to be influenced by broader schematic representations the person holds about themselves and other people, there has been little empirical examination of this, in particular in relation to beliefs about voice intent and the personal meaning of the voice experience. Method: Thirty-four voice hearers with a diagnosis of schizophrenia or schizoaffective disorder completed the Psychotic Symptom Rating Scales and measures of beliefs about voices (Revised Beliefs About Voices Questionnaire, Interpretation of Voices Inventory) and schemas (Brief Core Schema Scales). Results: Beliefs about voices were correlated with both negative voice content and schemas. After controlling for negative voice content, schemas were estimated to predict between 9% and 35% of variance in the six beliefs about voices that were measured. Negative-self schemas were the strongest predictors, and positive-self and negative-other schemas also showed potential relationships with beliefs about voices. Conclusions: Schemas, particularly those regarding the self, are potentially important in the formation of a range of clinically-relevant beliefs about voices. [ABSTRACT FROM PUBLISHER]

Abstract: Command hallucinations represent a special problem for the clinical management of psychosis. While compliance with both non-harmful and harmful commands can be problematic, sometimes in the extreme, active efforts to resist commands may also contribute to their malignancy. Previous research suggests Cognitive Behaviour Therapy (CBT) to be a useful treatment for reducing compliance with harmful command hallucinations. The purpose of this trial was to evaluate whether CBT augmented with acceptance-based strategies from Acceptance and Commitment Therapy could more broadly reduce the negative impact of command hallucinations. Forty-three participants with problematic command hallucinations were randomized to receive 15 sessions of the intervention “TORCH” (Treatment of Resistant Command Hallucinations) or the control, Befriending, then followed up for 6 months. A sub-sample of 17 participants was randomized to a waitlist control before being allocated to TORCH or Befriending. Participants engaged equally well with both treatments. Despite TORCH participants subjectively reporting greater improvement in command hallucinations compared to Befriending participants, the study found no significant group differences in primary and secondary outcome measures based on blinded assessment data. Within-group analyses and comparisons between the combined treatments and waitlist suggested, however, that both treatments were beneficial with a differential pattern of outcomes observed across the two conditions.

Background: The treatment of persisting psychotic symptoms with cognitive behavioural therapy (CBTp) is now established as an evidence-based treatment; however its availability remains limited. We piloted a novel CBTp skills-based group training program for carers. The aim was to reduce service users’ auditory hallucinations severity through carers’ use of basic CBTp methods in their regular interactions. Method: Eight carer-service user dyads and one carer-carer-service user triad participated. Carers attended the 10-week (25-hour) program, and completed measures of subjective burden and expressed emotion (EE) over a 30-week period that included a baseline phase prior to the training and implementation phase. Service users completed weekly interviews assessing voice symptomatology. Analyses were conducted for each dyad using time-series methods. Results: The training program was rated highly. Improvements in symptoms and carer burden ranged from none to clinically significant across different dyads. Carer implementation of strategies was related to reduced symptoms in one dyad; reductions in EE were related to symptom improvements in two dyads. Conclusions: There may be benefits in training carers in behavioural and cognitive management of persisting hallucinations. Possible mechanisms for improvements in voice symptomatology include reduction in carers’ EE, and carer implementation of strategies taught. [ABSTRACT FROM PUBLISHER]

Background: Cognitive behavioural therapy has been established as an effective treatment for residual psychotic symptoms but a substantial proportion of people do not benefit from this treatment. There has been little direct study of predictors of outcome, particularly in treatment targeting auditory hallucinations. Method: The Psychotic Symptom Rating Scales (PSYRATS) and Positive and Negative Syndrome Scale (PANSS) were administered pre- and post-therapy to 33 people with schizophrenia-related disorders receiving CBT for auditory hallucinations in a specialist clinic. Outcome was compared with pre-therapy measures of insight, beliefs about the origin of hallucinations, negative symptoms and cognitive disorganization. Results: There were significant improvements post-treatment on the PSYRATS and PANSS Positive and General Scales. Improvement on the PSYRATS was associated with lower levels of negative symptoms, but was unrelated to overall insight, delusional conviction regarding the origins of hallucinations, or levels of cognitive disorganization. Conclusions: Lack of insight and presence of formal thought disorder do not preclude effective cognitive-behavioural treatment of auditory hallucinations. There is a need to further understand why negative symptoms may present a barrier to therapy. [ABSTRACT FROM AUTHOR]

Objectives. The efficacy of cognitive behaviour therapies for psychosis (CBTp) has been sufficiently established for its inclusion in some national treatment guidelines. However, treatment efficacy does not guarantee effectiveness in routine practice, where clinician expertise and patient mix may be different. Thus, we evaluated the applicability, acceptability and effectiveness of CBTp when offered routinely in a public mental health service. Design. A prospectively recruited representative sample (N = 94) of patients with psychotic disorders from a geographic catchment area in Melbourne, Australia, was randomized to CBTp or treatment as usual. Method. The CBTp intervention included psychoeducation, positive symptom, and co-morbid problem components. Therapists collaboratively negotiated goals with patients and utilized treatment components from a manual. Intention-to-treat analyses used data at baseline, 9 months and 18 months. Results. Working alliance and client satisfaction measures indicated excellent acceptability. Both groups improved to a similar degree on the Positive And Negative Syndrome Scale, with no advantage for the CBTp group. The most frequent CBTp components implemented were co-morbid disorders/personal issues and personalized psychoeducation; working with persisting symptoms was the main focus in relatively few sessions. Conclusions. The lack of advantage for the CBTp group may be due to: the infrequent focus on positive symptoms (the most replicated outcome domain for CBTp); the unselected nature of the patients (rather than those with distressing symptoms or referred by clinicians); or, to insufficient therapist expertise.

Acceptance and mindfulness methods that emphasise the acceptance rather than control of symptoms are becoming more central to behavioural and cognitive therapies. Acceptance and Commitment Therapy (ACT) is the most developed of these methods; recent applications of ACT to psychosis suggest it to be a promising therapeutic approach. However, investigation of the mechanisms of therapy within this domain is difficult because there are no acceptance-based measures available specifically for psychotic symptoms. This paper describes the preliminary evaluation of a self-report instrument designed to assess acceptance-based attitudes and actions in relation to auditory and command hallucinations. Following initial scale development, a 56-item version of the Voices Acceptance and Action Scale (VAAS) was administered to 43 participants with command hallucinations as part of their baseline assessment in a larger trial. Measures of symptoms, quality of life, and depression were also administered. The scale was examined for reliability using corrected item total statistics. Based on this method, 31 items were retained. Internal consistency and test-retest reliability for the 31-item VAAS were acceptable. Subsequent examination of construct validity showed the VAAS to correlate significantly in the expected directions with depression, quality of life, and coping with command hallucinations. It also discriminated compliance from non-compliance with harmful command hallucinations. Although these results are preliminary and subject to a number of limitations, the VAAS shows promise as a useful aid in the assessment of the psychological impact of voices. © 2007 Wiley Periodicals, Inc.

Objective: This study aimed to better understand the implementation of cognitive behavioral therapy for psychosis (CBTp) by exploring the impact of clinicians' attitudes toward CBTp within the Theory of Planned Behavior framework (i.e., by considering attitudes, behaviors, intention, and social norms) as well as perceived obstacles and response to proposed solutions. Method: One hundred forty-two clinicians from 2 sites in Canada and 1 site in Australia answered an online survey involving both Likert scales and open-ended questions. The role of attitudes, social norms, and behavioral control (i.e., freedom to decide or act) on intention of offering CBTp delivering CBTp were analyzed using linear and logistic regressions. Sites were compared using analysis of variance. Reponses to perceived obstacles were thematically analyzed. Results: Results were similar across settings. Entered together in the model, attitudes, social norms, and behavioral control were significant in predicting the intention of offering CBTp, F(3, 125) = 38.49, p < .001, with 49% of the variance explained, although behavioral control did not significantly contribute to the model. CBTp training (odds ratio = 0.23, confidence interval = 0.06-0.58) and social norms (odds ratio = 0.79, confidence interval = 0.68-0.93) significantly predicted CBTp delivery. Six themes that emerged regarding perceived obstacles are provided. Training, supervision, and local support were the most frequently endorsed solutions. Brief or modular CBTp and group or online delivery were also positively endorsed. Conclusions and Implications for Practice: Clinicians' individual and collective attitudes should be targeted by more and better training to increase their delivery of CBTp. Given organizational barriers, CBTp-informed interventions warrant further investigation. [ABSTRACT FROM AUTHOR]
