Individual cognitive-behavior therapy in the treatment of hallucinations and delusions: a review

Defining Dementia Subtypes Through Neuropsychiatric Symptom-Linked Brain Connectivity Patterns

BACKGROUND

Dementia is highly heterogeneous, with pronounced individual differences in neuropsychiatric symptoms (NPS) and neuroimaging findings. Understanding the heterogeneity of NPS and associated brain abnormalities is essential for effective management and treatment of dementia.

METHODS

Using large-scale neuroimaging data from the Open Access Series of Imaging Studies (OASIS-3), we conducted a multivariate sparse canonical correlation analysis to identify functional connectivity-informed symptom dimensions. Subsequently, we performed a clustering analysis on the obtained latent connectivity profiles to reveal neurophysiological subtypes and examined differences in abnormal connectivity and phenotypic profiles between subtypes.

RESULTS

We identified two reliable neuropsychiatric subsyndromes - behavioral and anxiety in the connectivity-NPS linked latent space. The behavioral subsyndrome was characterized by the connections predominantly involving the default mode and somatomotor networks and neuropsychiatric symptoms involving nighttime behavior disturbance, agitation, and apathy. The anxiety subsyndrome was mainly contributed by connections involving the visual network and the anxiety neuropsychiatric symptom. By clustering individuals along these two subsyndromes-linked connectivity latent features, we uncovered three subtypes encompassing both dementia patients and healthy controls. Dementia in one subtype exhibited similar brain connectivity and cognitive-behavior patterns to healthy individuals. However, dementia in the other two subtypes showed different dysfunctional connectivity profiles involving the default mode, frontoparietal control, somatomotor, and ventral attention networks, compared to healthy individuals. These dysfunctional connectivity patterns were associated with differences in baseline dementia severity and longitudinal progression of cognitive impairment and behavioral dysfunction.

CONCLUSIONS

Our findings shed valuable insights into disentangling the neuropsychiatric and brain functional heterogeneity of dementia, offering a promising avenue to improve clinical management and facilitate the development of timely and targeted interventions for dementia patients.

Psychosis, symbol, affectivity 1: etiopathogenesis and treatment through analytical psychology

This is the first of two papers concerning our study into an integrated approach to psychotic disorders, conducted at the University of Palermo's Psychiatry Unit Polyclinic over approximately 15 years. Here we will explore and reflect upon the acute psychotic condition mainly from a theoretical and conceptual perspective, while in the second paper we will explore the clinical perspective. From the point of view of psychopathology, and in the light of C.G. Jung's conceptualization of analytical psychology, as well as calling on contributions from other authors from the systemic-relational and post-psychoanalytic field, we will clarify the ideas developed over these last few years by our team. From a more speculative perspective we will advance new interpretive hypotheses in an attempt to thoroughly understand the nature of the psychotic condition, both on a psychodynamic relational and a neuroscientific level. The paper describes how we revised our understanding of psychosis from a brain disease to a process aimed at the rearrangement of psychic functioning, as anticipated by John Weir Perry nearly 40 years ago.

Change in the Neural Response to Auditory Deviance Following Cognitive Therapy for Hallucinations in Patients With Schizophrenia

Adjunctive psychotherapeutic approaches recommended for patients with schizophrenia (SZ) who are fully or partially resistant to pharmacotherapy have rarely utilized biomarkers to enhance the understanding of treatment-effective mechanisms. As SZ patients with persistent auditory verbal hallucinations (AVH) frequently evidence reduced neural responsiveness to external auditory stimulation, which may impact cognitive and functional outcomes, this study examined the effects of cognitive behavioral therapy for voices (CBTv) on clinical and AVH symptoms and the sensory processing of auditory deviants as measured with the electroencephalographically derived mismatch negativity (MMN) response. Twenty-four patients with SZ and AVH were randomly assigned to group CBTv treatment or a treatment as usual (TAU) condition. Patients in the group CBTv condition received treatment for 5 months while the matched control patients received TAU for the same period, followed by 5 months of group CBTv. Assessments were conducted at baseline and at the end of treatment. Although not showing consistent changes in the frequency of AVHs, CBTv (vs. TAU) improved patients' appraisal (p = 0.001) of and behavioral/emotional responses to AVHs, and increased both MMN generation (p = 0.001) and auditory cortex current density (p = 0.002) in response to tone pitch deviants. Improvements in AVH symptoms were correlated with change in pitch deviant MMN and current density in left primary auditory cortex. These findings of improved auditory information processing and symptom-response attributable to CBTv suggest potential clinical and functional benefits of psychotherapeutical approaches for patients with persistent AVHs.

Treatment of Cognition in the Schizophrenia Spectrum: The Context of Psychiatric Rehabilitation

Evidence-based approaches and modalities for targeting and treating the cognitive impairments of schizophrenia have proliferated over the past 15 years. The impairments targeted are distributed across the cognitive spectrum, from elemental perception, attention, and memory, to complex executive and social-cognitive functioning. Cognitive treatment is most beneficial when embedded in comprehensive programs of psychiatric rehabilitation. To personalize comprehensive treatment and rehabilitation of schizophrenia spectrum disorders, practitioners and participants must select from a rapidly expanding array of particular modalities and apply them in the broad context of the participant's overall recovery. At present, no particular treatment, cognitive or otherwise, can be considered more important or primary than the context in which it is applied. Persistent difficulty in dissemination of new technology for severe and disabling mental illness compounds the significance of the context created by a full treatment array. In this article, a case-study of a mental health service system is described, showing the broad-ranging effects of degrading the rehabilitative context of treatments, obviating the benefits of cognitive treatment and other modalities. To realize the promise of cognitive treatment, the problems that prevent dissemination and maintenance of complete psychiatric rehabilitation programs have to be addressed.

Word use in first-person accounts of schizophrenia

BACKGROUND

Language use is often disrupted in patients with schizophrenia; novel computational approaches may provide new insights.

AIMS

To test word use patterns as markers of the perceptual, cognitive and social experiences characteristic of schizophrenia.

METHOD

Word counting software was applied to first-person accounts of schizophrenia and mood disorder.

RESULTS

More third-person plural pronouns ('they') and fewer first-person singular pronouns ('I') were used in schizophrenia than mood disorder accounts. Schizophrenia accounts included fewer words related to the body and ingestion, and more related to religion. Perceptual and causal language were negatively correlated in schizophrenia accounts but positively correlated in mood disorder accounts.

CONCLUSIONS

Differences in pronouns suggest decreased self-focus or perhaps even an understanding of self as other in schizophrenia. Differences in how perceptual and causal words are correlated suggest that long-held delusions represent a decreased coupling of explanations with sensory experience over time.

Training to recognise the early signs of recurrence in schizophrenia

BACKGROUND

Schizophrenia has a lifetime prevalence of less than one per cent. Studies have indicated that early symptoms that are idiosyncratic to the person with schizophrenia (early warning signs) often precede acute psychotic relapse. Early warning signs interventions propose that learning to detect and manage early warning signs of impending relapse might prevent or delay acute psychotic relapse.

OBJECTIVES

To compare the effectiveness of early warning signs interventions plus treatment as usual involving and not involving a psychological therapy on time to relapse, hospitalisation, functioning, negative and positive symptomatology.

SEARCH METHODS

Search databases included the Cochrane Schizophrenia Group Trials Register (July 2007 and May 2012) which is based on regular searches of BIOSIS, CENTRAL, CINAHL, EMBASE, MEDLINE and PsycINFO. References of all identified studies were reviewed for inclusion. We inspected the UK National Research Registe and contacted relevant pharmaceutical companies and authors of trials for additional information.

SELECTION CRITERIA

We included all randomised clinical trials (RCTs) comparing early warning signs interventions plus treatment as usual to treatment as usual for people with schizophrenia or other non-affective psychosis

DATA COLLECTION AND ANALYSIS

We assessed included studies for quality and extracted data. If more than 50% of participants were lost to follow-up, the study was excluded. For binary outcomes, we calculated standard estimates of risk ratio (RR) and the corresponding 95% confidence intervals (CI), for continuous outcomes, we calculated mean differences (MD) with standard errors estimated, and for time to event outcomes we calculated Cox proportional hazards ratios (HRs) and associated 95 % CI. We assessed risk of bias for included studies and assessed overall study quality using the GRADE approach.

MAIN RESULTS

Thirty-two RCTs and two cluster-RCTs that randomised 3554 people satisfied criteria for inclusion. Only one study examined the effects of early warning signs interventions without additional psychological interventions, and many of the outcomes for this review were not reported or poorly-reported. Significantly fewer people relapsed with early warning signs interventions than with usual care (23% versus 43%; RR 0.53, 95% CI 0.36 to 0.79; 15 RCTs, 1502 participants; very low quality evidence). Time to relapse did not significantly differ between intervention groups (6 RCTs, 550 participants; very low quality evidence). Risk of re-hospitalisation was significantly lower with early warning signs interventions compared to usual care (19% versus 39%; RR 0.48, 95% CI 0.35 to 0.66; 15 RCTS, 1457 participants; very low quality evidence). Time to re-hospitalisation did not significantly differ between intervention groups (6 RCTs; 1149 participants; very low quality evidence). Participants' satisfaction with care and economic costs were inconclusive because of a lack of evidence.

AUTHORS' CONCLUSIONS

This review indicates that early warning signs interventions may have a positive effect on the proportions of people re-hospitalised and on rates of relapse, but not on time to recurrence. However, the overall quality of the evidence was very low, indicating that we do not know if early warning signs interventions will have similar effects outside trials and that it is very likely that further research will alter these estimates. Moreover, the early warning signs interventions were used along side other psychological interventions, and we do not know if they would be effective on their own. They may be cost-effective due to reduced hospitalisation and relapse rates, but before mental health services consider routinely providing psychological interventions involving the early recognition and prompt management of early warning signs to adults with schizophrenia, further research is required to provide evidence of high or moderate quality regarding the efficacy of early warning signs interventions added to usual care without additional psychological interventions, or to clarify the kinds of additional psychological interventions that might aid its efficacy. Future RCTs should be adequately-powered, and designed to minimise the risk of bias and be transparently reported. They should also systematically evaluate resource costs and resource use, alongside efficacy outcomes and other outcomes that are important to people with serious mental illness and their carers.

Early interventions to prevent psychosis: systematic review and meta-analysis

OBJECTIVE

To determine whether any psychological, pharmacological, or nutritional interventions can prevent or delay transition to psychotic disorders for people at high risk.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Embase, Medline, PreMedline, PsycINFO, and CENTRAL were searched to November 2011 without restriction to publication status.

REVIEW METHODS

Randomised trials comparing any psychological, pharmacological, nutritional, or combined intervention with usual services or another treatment. Studies of participants with a formal diagnosis of schizophrenia or bipolar disorder were excluded. Studies were assessed for bias, and relevant limitations were considered in summarising the results.

RESULTS

11 trials including 1246 participants and eight comparisons were included. Median sample size of included trials was 81 (range 51-288). Meta-analyses were performed for transition to psychosis, symptoms of psychosis, depression, and mania; quality of life; weight; and discontinuation of treatment. Evidence of moderate quality showed an effect for cognitive behavioural therapy on reducing transition to psychosis at 12 months (risk ratio 0.54 (95% confidence interval 0.34 to 0.86); risk difference -0.07 (-0.14 to -0.01). Very low quality evidence for omega-3 fatty acids and low to very low quality evidence for integrated psychotherapy also indicated that these interventions were associated with reductions in transition to psychosis at 12 months.

CONCLUSIONS

Although evidence of benefits for any specific intervention is not conclusive, these findings suggest that it might be possible to delay or prevent transition to psychosis. Further research should be undertaken to establish conclusively the potential for benefit of psychological interventions in the treatment of people at high risk of psychosis.

Narrative enhancement and cognitive therapy: a new group-based treatment for internalized stigma among persons with severe mental illness

Internalized stigma has been suggested to play a major role in negative changes in identity in severe mental illness. Evidence suggests that roughly one-third of people with severe mental illness show elevated internalized stigma and that it is linked to compromised outcomes in both subjective and objective aspects of recovery. Despite substantial evidence for the impact of internalized stigma, few efforts have been made to develop professionally led treatment to address this issue. In this article, we discuss our development of a new group-based approach to the treatment of internalized stigma which we have termed "narrative enhancement and cognitive therapy (NECT)". We describe the treatment approach and offer an illustration of it by way of a case vignette.

Insights into hallucinations in schizophrenia: novel treatment approaches

Novel strategies are needed in the treatment of hallucinations as a subgroup of patients with pathological hallucinations (>30%) do not respond to antipsychotics or are not compliant with medication. We review recently developed biological and cognitive treatments. Repetitive transcranial magnetic stimulation concerns neuromodulation targeted at aberrant activity in regions shown to be hyperactive in neuroimaging studies. Repetitive transcranial magnetic stimulation has been shown to reduce auditory hallucinations in several studies. However, not all studies have confirmed such effects, and a number of questions remain. With regard to cognitive therapeutic approaches, new proposals include attention training, acceptance and commitment therapy, and competitive memory training. After a brief discussion of these approaches, we take stock of recent advances and discuss avenues for future research.

A two-year cross-sectional study on the information about schizophrenia divulged by a prestigious daily newspaper

Media is an important source of information about mental health for the public. The current study analyzed the information about schizophrenia divulged by the largest Brazilian newspaper. A content analysis examined articles on health and news involving affected individuals or suspected cases. The articles were rated against indicators of poor quality reporting and of effective health communication. The presence of myths was examined. The search identified 687 articles, 75 of which fulfilled the inclusion/exclusion criteria and were selected. The themes with the highest number of articles were mental disorders and violence, treatment, and etiology. Three articles described the social inclusion stories of affected individuals. The coverage addressed genetic factors, drug-induced psychosis risk, and antipsychotic benefits, which may contribute to stigma reduction toward treatment. However, the articles divulged stigmatizing messages, and the entire complexity of the disorder was not discussed. Dangerousness was a common theme, which may invalidate positive messages about social inclusion.

A pathway to personalization of integrated treatment: informatics and decision science in psychiatric rehabilitation

Personalization of treatment is a current strategic goal for improving health care. Integrated treatment approaches such as psychiatric rehabilitation benefit from personalization because they involve matching diverse arrays of treatment options to individually unique profiles of need. The need for personalization is evident in the heterogeneity of people with severe mental illness and in the findings of experimental psychopathology. One pathway to personalization lies in analysis of the judgments and decision making of human experts and other participants as they respond to complex circumstances in pursuit of treatment and rehabilitation goals. Such analysis is aided by computer simulation of human decision making, which in turn informs development of computerized clinical decision support systems. This inspires a research program involving concurrent development of databases, domain ontology, and problem-solving algorithms, toward the goal of personalizing psychiatric rehabilitation through human collaboration with intelligent cyber systems. The immediate hurdle is to demonstrate that clinical decisions beyond diagnosis really do affect outcome. This can be done by supporting the hypothesis that a human treatment team with access to a reasonably comprehensive clinical database that tracks patient status and treatment response over time achieves better outcome than a treatment team without such access, in a controlled experimental trial. Provided the hypothesis can be supported, the near future will see prototype systems that can construct an integrated assessment, formulation, and rehabilitation plan from clinical assessment data and contextual information. This will lead to advanced systems that collaborate with human decision makers to personalize psychiatric rehabilitation and optimize outcome.

Development of depressed mood predicts onset of psychotic disorder in individuals who report hallucinatory experiences

OBJECTIVES

Current psychological theories state that the clinical outcome of hallucinatory experiences is dependent on the degree of associated distress, anxiety, and depression. This study examined the hypothesis that the risk for onset of psychotic disorder in individuals with self-reported hallucinatory experiences would be higher in those who subsequently developed depressed mood than in those who did not.

DESIGN

A prospective cohort study of a general population sample.

METHODS

A sample of 4,670 individuals with no lifetime evidence of any psychotic disorder were interviewed with the Composite International Diagnostic Interview Schedule (CIDI) at baseline and 1 and 3 years later. At Year 3, individuals with CIDI evidence of psychotic symptoms were interviewed by clinicians to identify potential onset of psychotic disorder. Psychotic disorder was specified at three levels; two involving severity of positive symptoms of psychosis, and one using additional clinical judgment of need for care.

RESULTS

Given the presence of hallucinatory experiences at baseline, the increase in risk of having the psychosis outcome at Year 3 was higher in the group with depressed mood at Year 1 than in the group without depressed mood at Year 1 (any level of psychotic symptoms: risk difference 17.0%, 95% CI - 1.7, 35.7; severe level of psychotic symptoms: risk difference 21.7%, 95% CI 3.2, 40.2; needs-based diagnosis of psychotic disorder: risk difference 16.8%, 95% CI 0.4, 33.3).

CONCLUSION

The results are in line with current psychological models of psychosis that emphasize the role of secondary appraisals of psychotic experiences in the onset of clinical disorder.

Autobiography as tool to improve lifestyle, well being, and self-narrative in patients with mental disorders

The aims of the present study were to explore how the autobiographical process can lead to a transformation in psychiatric patients' lifestyle, well-being, and self-narrative. Nine participants, aged between 20 and 42 years and affected by axis I psychiatric disorders (DSM IV) were selected to participate in an autobiographical laboratory. Eight to 10 meetings took place, each lasting about an hour, during which autobiographical accounts were collected. At the beginning and end of the autobiographical laboratory, the medical staff completed the Social Functioning Scale to evaluate each patient across 6 dimensions: social engagement, interpersonal ability, prosocial activities, recreation, independence-competence, and independence-performance. The Language Inquiry and Word Count (Pennebaker and Francis, 1996) was used to analyze patients' autobiographical accounts. A comparison between the first and second compilation of the Social Functioning Scale showed significant positive changes across the 6 social dimensions. The analysis of language in the narratives collected in the first and seventh meeting showed how inpatients passed from a narrative that was more centered on the memory of the past to a narrative that was more similar to a conversation and enriched with "insight" terms and the use of verbs in the conjunctive form. The authors interpret these outcomes as being consistent with the improvement that was observed in inpatients' social functioning.

Randomized controlled trial of interventions for young people at ultra-high risk of psychosis: study design and baseline characteristics

OBJECTIVE

Intervention during the pre-psychotic period of illness holds the potential of delaying or even preventing the onset of a full-threshold disorder, or at least of reducing the impact of such a disorder if it does develop. The first step in realizing this aim was achieved more than 10 years ago with the development and validation of criteria for the identification of young people at ultra-high risk (UHR) of psychosis. Results of three clinical trials have been published that provide mixed support for the effectiveness of psychological and pharmacological interventions in preventing the onset of psychotic disorder.

METHOD

The present paper describes a fourth study that has now been undertaken in which young people who met UHR criteria were randomized to one of three treatment groups: cognitive therapy plus risperidone (CogTher + Risp: n = 43); cognitive therapy plus placebo (CogTher + Placebo: n = 44); and supportive counselling + placebo (Supp + Placebo; n = 28). A fourth group of young people who did not agree to randomization were also followed up (monitoring: n = 78). Baseline characteristics of participants are provided.

RESULTS AND CONCLUSION

The present study improves on the previous studies because treatment was provided for 12 months and the independent contributions of psychological and pharmacological treatments in preventing transition to psychosis in the UHR cohort and on levels of psychopathology and functioning can be directly compared. Issues associated with recruitment and randomization are discussed.

Relapse prevention in serious and enduring mental illness: a pilot study

The purpose of the research was to ascertain whether coping knowledge and relapse outcomes are enhanced after 12 months following a programme of community-based relapse prevention (RP). Relapse to mental illness has high societal costs and this programme aims to lessen the likelihood of relapse by equipping service users with greater coping mechanisms by employing a quasi-experimental design with some controls. Participants are recruited from a day hospital in London. There are two groups: (1) experimental group (n = 10) and (2) control group (n = 10). The experimental group is given an 8-week RP programme, and the control group receives routine care. Both groups are then followed up at 1, 2 and 12 months. The research hypothesis was participants undergoing a programme of RP will have greater 12-month knowledge and superior relapse outcomes. The 52-week follow-up rates are 80% for experimental group and 70% for control group. There are no differences in the two groups in terms of relapse outcomes. Knowledge between baseline and 52 weeks is improved in the experimental group though most of the changes are observed during the first 12 weeks. We conclude that an 8-week RP programme resulted in improved knowledge but not relapse outcomes at 52 weeks. A randomized controlled trial should now be conducted to assess whether these results are replicated.

Autobiography as a tool for self-construction: a study of patients with mental disorders

The aim of the present study was to explore how the autobiographical process can lead to a transformation in the quality of psychiatric patients' self-narrative. Fifteen participants, with ages ranging from 25 to 40 years and affected by axis I psychiatric disorders (DSM IV), were selected to participate. A 10-question interview referring to 10 autobiographical cruxes was used to collect autobiographical data; the interview was readministered 2 weeks later. A coding system (the N.O.I.S.) was used to analyze each participant's 2 autobiographical productions. Results from the second interviews showed significant and positive transformations in the quality of patients' autobiographical representation.

Identifying mechanisms of treatment effects and recovery in rehabilitation of schizophrenia: longitudinal analytic methods

The longitudinal dimension of schizophrenia and related severe mental illness is a key component of theoretical models of recovery. However, empirical longitudinal investigations have been underrepresented in the psychopathology of schizophrenia. Similarly, traditional approaches to longitudinal analysis of psychopathological data have had serious limitations. The utilization of modern longitudinal methods is necessary to capture the complexity of biopsychosocial models of treatment and recovery in schizophrenia. The present paper summarizes empirical data from traditional longitudinal research investigating recovery in symptoms, neurocognition, and social functioning. Studies conducted under treatment as usual conditions are compared to psychosocial intervention studies and potential treatment mechanisms of psychosocial interventions are discussed. Investigations of rehabilitation for schizophrenia using the longitudinal analytic strategies of growth curve and time series analysis are demonstrated. The respective advantages and disadvantages of these modern methods are highlighted. Their potential use for future research of treatment effects and recovery in schizophrenia is also discussed.

The conviction of delusional beliefs scale: reliability and validity

This study reports on the development of a new measure of delusional belief conviction, the Conviction of Delusional Beliefs Scale (CDBS). Most of the current scales in use assess belief conviction with a single item and primarily reflect the cognitive aspects of conviction. The CDBS represents an improvement over existing scales in that it contains a larger number of test items that can be subjected to psychometric examination. In addition, the CDBS also broadens the concept of belief conviction by incorporating cognitive, emotional, and behavioral items. In the present study, fifty participants with delusions completed the CDBS along with measures of delusional ideation, psychiatric symptomatology, insight, and reading ability. The CDBS showed very good levels of internal consistency and test-retest stability over a six-week period. All of the CDBS items loaded highly on a unitary factor of belief conviction. The CDBS positively correlated with four measures of belief conviction thereby reflecting the convergent validity of the scale. The CDBS was unrelated to other dimensions of delusional ideation, psychiatric symptomatology, insight, and reading ability, which supported the discriminant validity of the scale. The CDBS appears to be a reliable and valid measure of delusional belief conviction that could be used in clinical and research settings.

Cognitive intervention for voice hearers

Cognitive behavioral therapy is an emerging treatment being used to attenuate negative thoughts and emotions tied to the formation, expression, and maintenance of verbal auditory hallucinations. This paper describes the theoretical underpinnings for the intervention and a clinical application of a prototype cognitive nursing intervention for treating faulty thinking and beliefs linked with problematic voice hearing experiences. The paper ends with a review of current evidence and implications concerning the efficacy of cognitive intervention approaches with voice hearers.

"Hitting" voices of schizophrenia patients may lastingly reduce persistent auditory hallucinations and their burden: 18-month outcome of a randomized controlled trial

OBJECTIVE

This study aimed to investigate the outcome of an 18-month randomized controlled trial (RCT) on subjective burden and psychopathology of patients suffering from schizophrenia.

METHOD

An RCT was used to compare hallucination-focused integrative treatment (HIT) and routine treatment (RT) in schizophrenia patients who persistently hear voices. We performed an intent-to-treat analysis on each of the 63 patients who were assessed at baseline, 9, and 18 months. On each of the 3 occasions, the differential effects of the treatment conditions were tested repeatedly. Sex, age, education, and illness (hallucination) duration were used as covariates.

RESULTS

Patients in the experimental group retained improvements over time. Improvements in hallucinations, distress, and negative content of voices remained significant at the 5% level.

CONCLUSION

HIT seems to be an effective treatment strategy with long-lasting effects for treatment-refractory voice-hearing patients.

Narrative as an outcome domain in psychosis

A recent renewed interest in psychosocial treatments for psychosis has only minimally included considerations of narrative therapy and other interventions based in post-modernism. This lack of attention is curious given the profound narrative disruptions often seen in psychotic illness. In this review article we describe several studies in which narratives and narrative dimensions have been utilized to assess outcomes in psychosis. Valid and reliable measures of narrative change in psychosis are possible and can coexist with and complement traditional outcome measures. Perhaps more significantly, considerations of narrative changes may offer unique insights into the process of recovery from psychosis as well as leading to beneficial psychosocial treatments for the same.

Associations of symptoms, psychosocial function and hope with qualities of self-experience in schizophrenia: comparisons of objective and subjective indicators of health

While changes in self-experience have been suggested to be an important element of recovery from severe mental illness, little is known about how qualities of self-experience are linked with other indicators of health including objective measures such as symptoms profiles and subjective measures such as hope. To examine these issues the narratives of self and illness of 65 persons with schizophrenia spectrum disorder were obtained prior to entry into rehabilitation and rated using the Scale to Assess Narrative Development (STAND). STAND scores were then compared with concurrent assessments of hope assessed with the Beck Hopelessness Scale (BHS), psychosocial function using the Quality of Life Scale (QOLS) and symptom profile defined categorically using the Positive and Negative Syndrome Scale (PANSS). Results suggest that higher ratings of the STAND were associated with greater expectations of perseverance on the BHS and higher levels of psychosocial function on the QOL. Lower symptom profiles were similarly linked with higher STAND scores. Results suggest qualities of self-experience expressed within personal narratives are linked to symptom profiles and subjective assessments of health. Theoretical and clinical implications are discussed.

Multi-family treatment for patients with persistent auditory hallucinations and their relatives: a pilot study

OBJECTIVE

To test feasibility and effectiveness of multi-family treatment (MFT) for patients with persistent auditory hallucinations.

METHOD

A naturalistic pilot study with 6-month follow-up of 12 patients and 10 relatives. Pre- and post-treatment assessment concerned compliance, satisfaction, subjective burden, and control of voices, psychopathology, quality of life, social functioning and burden on the family.

RESULTS

Significant improvements were found in all domains. Compliance and satisfaction with treatment were satisfactory. Self-help contacts outside treatment sessions increased over time.

CONCLUSION

MFT may be considered a potentially effective form of additional treatment for refractory voice hearers.

The effect of cognitive behavioral treatment on the positive symptoms of schizophrenia spectrum disorders: a meta-analysis

BACKGROUND

Despite the effectiveness of anti-psychotic pharmacotherapy, residual hallucinations and delusions do not completely resolve in some medicated patients. Additional cognitive behavioral therapy (CBT) seems to improve the management of positive symptoms. Despite promising results, the efficacy of CBT is still unclear. The present study addresses this issue taking into account a number of newly published controlled studies.

METHOD

Fourteen studies including 1484 patients, published between 1990 and 2004 were identified and a meta-analysis of their results performed.

RESULTS

Compared to other adjunctive measures, CBT showed significant reduction in positive symptoms and there was a higher benefit of CBT for patients suffering an acute psychotic episode versus the chronic condition (effect size of 0.57 vs. 0.27).

DISCUSSION

CBT is a promising adjunctive treatment for positive symptoms in schizophrenia spectrum disorders. However, a number of potentially modifying variables have not yet been examined, such as therapeutic alliance and neuropsychological deficits.

Understanding the incomprehensible: Private theories of first–episode psychotic patients and their therapists

Private theories about psychosis, its background, and cure were studied using narratives of first-time psychotic patients and their therapists. Both patients and their therapists were interviewed on three occasions over a period of 1 1/2 years. Three cases were chosen as dyads in point in order to highlight different relations between the patient's and the therapist's private theories, different patterns of recovery from psychosis, and different outcomes. The cases are contrasted by paired comparisons. The study indicates that an awareness and joint discussion of incompatibilities between the two participants' private theories might be a substantial contribution to the process of recovery from psychosis.

Update on Cognitive Behavioral Psychotherapy for Schizophrenia: Review of Recent Studies

Cognitive-behavioral psychotherapy (CBT) for schizophrenia has been the focus of clinical trials. This article reviews 17 recent studies including 5 from the United States or Canada. CBT interventions vary by the patient group to whom they are provided. Both individual and group CBT therapies have been developed, some of which have been combined with other psychosocial treatments. There is inconsistency among the study results, but evidence is strongest for the benefit to outpatients who have residual symptoms including hallucinations, delusions, or negative symptoms. Methodological issues include the type of comparison group used, the adequacy of the sample size, and patient attrition. Future investigations of CBT would be improved by a greater standardization of study procedures and by stratifying patients according to clinical characteristics to better understand which patients are more likely to benefit.

Redefining delusion based on studies of subjective paranormal ideation

The DSM-IV definition of delusion is argued to be unsatisfactory because it does not explain the mechanism for delusion formation and maintenance, it implies that such beliefs are necessarily dysfunctional (pathological), it underestimates the social component to some delusions, and it is inconsistent with research indicating that delusions can be modified through techniques such as contradiction, confrontation, and cognitive-behavioral therapy. However, a well-replicated mathematical model of magical/delusional thinking based on a study of paranormal beliefs and experiences is consistent with the hypothesis that attributional processes play a central role in delusion formation and maintenance. The model suggests attributional processes serve the adaptive function of reducing fear associated with ambiguous stimuli and delusional thinking is on a continuum with nonpathological forms. Based on this collective research an amendment to the definition of delusion is proposed and its clinical implications are addressed.

Implementing evidence-based practices for people with severe mental illness

Persons with severe mental illnesses (SMI) often lack access to effective treatments. The authors describe the Implementing Evidence-Based Practices (EBPs) Project, designed to increase access for people with SMI to empirically supported interventions. The EBP Project aims to improve access through development of standardized implementation packages, created in collaboration with different stakeholders, including clinicians, consumers, family members, clinical supervisors, program leaders, and mental health authorities. The background and philosophy of the EBP Project are described, including the six EBPs identified for initial package development: collaborative psychopharmacology, assertive community treatment, family psychoeducation, supported employment, illness management and recovery skills, and integrated dual disorders treatment. The components of the implementation packages are described as well as the planned phases of the project. Improving access to EBPs for consumers with SMI may enhance outcomes in a cost-effective manner, helping them pursue their personal recovery goals with the support of professionals, family, and friends.

The cognitive-behavioural treatment of low self-esteem in psychotic patients: a pilot study

Low self esteem in individuals with a psychotic disorder is common and may be related to poorer clinical outcomes. However, there has been little research on devising treatment methods to improve self-esteem either generally or in psychotic patients in particular. The aims of this study were to evaluate the efficacy of a simple cognitive behavioural intervention to improve self esteem in psychotic patients who scored poorly on a self-esteem measure. This pilot study was a randomised control trial with a convenience sample of chronic psychotic inpatients. The cognitive behavioural self-esteem intervention, as an adjunct to treatment as usual (TAU), was compared to TAU alone in patients with psychosis. The individual self-esteem intervention as described by Tarrier (The use of coping strategies and self-regulation in the treatment of psychosis. (2001)) consisted of working with participants to elicit positive self-attributes and then identify specific behavioural examples to provide evidence of this attribute. Emphasis was given to any consequential change in the patient's belief that they had the attribute. The results indicated that this cognitive behavioural treatment for self-esteem used as an adjunct treatment in psychosis, resulted in clinical benefits in terms of increased self-esteem, decreased psychotic symptomatology and improved social functioning. These benefits were largely maintained at 3-month follow-up.

Time series models of symptoms in schizophrenia

The symptom courses of 84 schizophrenia patients (mean age: 24.4 years; mean previous admissions: 1.3; 64% males) of a community-based acute ward were examined to identify dynamic patterns of symptoms and to investigate the relation between these patterns and treatment outcome. The symptoms were monitored by systematic daily staff ratings using a scale composed of three factors: psychoticity, excitement, and withdrawal. Patients showed moderate to high symptomatic improvement documented by effect size measures. Each of the 84 symptom trajectories was analyzed by time series methods using vector autoregression (VAR) that models the day-to-day interrelations between symptom factors. Multiple and stepwise regression analyses were then performed on the basis of the VAR models. Two VAR parameters were found to be associated significantly with favorable outcome in this exploratory study: 'withdrawal preceding a reduction of psychoticity' as well as 'excitement preceding an increase of withdrawal'. The findings were interpreted as generating hypotheses about how patients cope with psychotic episodes.

Decision Making and Personality Disorders

Individuals with different personality disorders are hypothesized to approach decision making with a variety of concerns related to their perception of their general efficacy, information demands, risk aversion, and utility of gains and losses. A variation of modern portfolio theory is employed to examine decision-making in a clinical population of adult patients. Variations along personality dimensions were related to a number of decision-making concerns and strategies. The implications of these findings are examined in the clinical treatment of personality disorders.

Cognitive therapy for psychosis in schizophrenia: an effect size analysis

We conducted a meta-analysis using all available controlled treatment outcome studies of cognitive therapy (CT) for psychotic symptoms in schizophrenia. Effect sizes were calculated for seven studies involving 340 subjects. The mean effect size for reduction of psychotic symptoms was 0.65. The findings suggest that cognitive therapy is an effective treatment for patients with schizophrenia who have persistent psychotic symptoms. Follow-up analyses in four studies indicated that patients receiving CT continued to make gains over time (ES=0.93). Further research is needed to determine the replicability of standardized cognitive interventions, to evaluate the clinical significance of cognitive therapy for schizophrenia, and to determine which patients are most likely to benefit from this intervention.

Cognitive behavioral psychotherapy for schizophrenia: a review of recent empirical studies

A set of cognitive behavioral psychotherapies (CBT) has been developed for schizophrenia. These interventions have been used for the treatment of both recent onset patients and those with treatment-refractory symptoms. This article reviews clinical trials of CBT for schizophrenia since 1990. The CBT interventions appear to be beneficial in reducing overall symptom levels, especially the severity of delusions. The relative efficacy of CBT is more evident when CBT is compared with routine care than when it is compared with other therapies matched for therapist attention. Further studies are needed to objectively determine the active ingredients of CBT and to better identify the interactions of CBT with concurrent psychosocial and medication treatments.

Randomised controlled effectiveness trial of a needs-based psychosocial intervention service for carers of people with schizophrenia

BACKGROUND

Family interventions are effective in reducing relapse in patients with schizophrenia, but there is little work demonstrating the effectiveness of the interventions in routine service settings.

AIMS

To test the effectiveness of a needs-based family intervention service for patients recruited as out-patients and their carers, including those of low expressed emotion status.

METHOD

Carers of out-patient schizophrenia sufferers selected only on illness history factors were randomly allocated to receive either family support alone or in combination with systematic psychosocial interventions based on an assessment of need. Delivery of family interventions attempted to involve the clinical team.

RESULTS

Relapse outcomes were superior for family-treated patients at six-month follow-up, although most of the clinical and symptom patient variables assessed remained stable, as did measures of carer burden.

CONCLUSIONS

The study demonstrated the effectiveness of family interventions in routine service settings. Problems with staff, patient and carer engagement and participation were identified.

Randomised controlled trial of intensive cognitive behaviour therapy for patients with chronic schizophrenia

OBJECTIVES

To investigate whether intensive cognitive behaviour therapy results in significant improvement in positive psychotic symptoms in patients with chronic schizophrenia.

DESIGN

Patients with chronic schizophrenia were randomly allocated, stratified according to severity of symptoms and sex, to intensive cognitive behaviour therapy and routine care, supportive counselling and routine care, and routine care alone.

SETTING

Adjunct treatments were carried out in outpatient clinics or in the patient's home.

SUBJECTS

87 patients with persistent positive symptoms who complied with medication; 72 completed treatment.

OUTCOME MEASURES

Assessments of positive psychotic symptoms before treatment and 3 months after treatment. Number of patients who showed a 50% or more improvement in symptoms. Exacerbation of symptoms and rates of readmission to hospital.

RESULTS

Significant improvements were found in the severity (F=5.42, df =2,86; P=0.006) and number (F=4.99, df=2,86; P=0.009) of positive symptoms in those treated with cognitive behaviour therapy. The supportive counselling group showed a non-significant improvement. Significantly more patients treated with cognitive behaviour therapy showed an improvement of 50% or more in their symptoms (chi2=5.18, df=1; P=0.02). Logistic regression indicated that receipt of cognitive behaviour therapy results in almost eight times greater odds (odds ratio 7.88) of showing this improvement. The group receiving routine care alone also experienced more exacerbations and days spent in hospital.

CONCLUSIONS

Cognitive behaviour therapy is a potentially useful adjunct treatment in the management of patients with chronic schizophrenia.
