The COMMAND trial of cognitive therapy to prevent harmful compliance with command hallucinations: predictors of outcome and mediators of change.

BACKGROUND: Acting on harmful command hallucinations is a major clinical concern. Our COMMAND CBT trial approximately halved the rate of harmful compliance (OR = 0.45, 95% CI 0.23-0.88, p = 0.021). The focus of the therapy was a single mechanism, the power dimension of voice appraisal, was also significantly reduced. We hypothesised that voice power differential (between voice and voice hearer) was the mediator of the treatment effect. METHODS: The trial sample (n = 197) was used. A logistic regression model predicting 18-month compliance was used to identify predictors, and an exploratory principal component analysis (PCA) of baseline variables used as potential predictors (confounders) in their own right. Stata's paramed command used to obtain estimates of the direct, indirect and total effects of treatment. RESULTS: Voice omnipotence was the best predictor although the PCA identified a highly predictive cognitive-affective dimension comprising: voices' power, childhood trauma, depression and self-harm. In the mediation analysis, the indirect effect of treatment was fully explained by its effect on the hypothesised mediator: voice power differential. CONCLUSION: Voice power and treatment allocation were the best predictors of harmful compliance up to 18 months; post-treatment, voice power differential measured at nine months was the mediator of the effect of treatment on compliance at 18 months.

Cognitive Behavioural Suicide Prevention for Male Prisoners: Case examples.

Suicide is a serious public health problem but a problem that is preventable. This complex and challenging problem is particularly prevalent amongst prisoners; associated with a five-fold increase in risk compared to the general community. Being in prison can lead people to experience fear, distrust, lack of control, isolation, and shame, which is often experienced as overwhelming and intolerable with some choosing suicide as a way to escape. Few effective psychological interventions exist to prevent suicide although cognitive behaviour therapies appear to offer some promise. Offering cognitive behaviour suicide prevention (CBSP) therapy to high risk prisoners may help to reduce the likelihood of preventable self-inflicted deaths. In this paper we present three cases drawn from a randomised controlled trial designed to investigate the feasibility of CBSP for male prisoners. Implications of the current findings for future research and clinical practice are considered.

Suicidality and posttraumatic stress disorder (PTSD) in adolescents: a systematic review and meta-analysis.

PURPOSE: There is growing evidence in the literature that a diagnosis of Posttraumatic Stress Disorder (PTSD) is an important contributory factor to suicidality in adolescents. However, there is no existing review of the literature examining the relationship between PTSD and suicidality in adolescents. This study aims to provide the first systematic review and meta-analysis of the association between PTSD and suicidality in adolescents. METHODS: Five bibliographic databases (Medline, EMBASE, PsycINFO, Web of Science and PILOT) were screened for suitable articles. Twenty-eight studies (which provided 28 independent samples) were included in the review. The overall meta-analyses of the association between PTSD and suicidality were followed by subgroup and meta-regression analyses. RESULTS: A highly significant positive association was found between PTSD and suicidality (d = 0.701, 95% CI 0.555-0.848). The subgroup and meta-regression analyses showed that the association between PTSD and suicidality persisted whilst adjusting for various sources of between-study heterogeneity, such as, different levels of severity of suicidality, target groups, and methodological quality of the studies. CONCLUSIONS: Suicidality in adolescents with PTSD is a major problem which requires further research effort. The implications of these results are discussed.

A prospective study of suicidal ideation in posttraumatic stress disorder: the role of perceptions of defeat and entrapment.

OBJECTIVES: This study aimed to provide the first prospective test of the ability of defeat and entrapment to predict suicidal ideation in posttraumatic stress disorder (PTSD) after controlling for the effects of PTSD severity, comorbid depressive symptoms, and hopelessness on suicidal ideation. METHODS: Participants were 52 individuals diagnosed with PTSD. Baseline and follow-up assessments were 13 to 15 months apart. Defeat and entrapment were conceptualized and analyzed as a unique construct (defeat/entrapment) in this study. Multiple regression analysis was applied to examine the predictive effects of defeat/entrapment on suicidal ideation. RESULTS: Defeat/entrapment scores predicted changes in the levels of suicidal ideation at follow-up while controlling for baseline suicidal ideation, PTSD severity, comorbid depressive symptoms, and hopelessness. CONCLUSIONS: These outcomes provide support to contemporary models of suicidality that suggest that defeat/entrapment is a strong predictor of suicidality in PTSD.

Outcomes following hip fracture surgery: a 2-year prospective study.

OBJECTIVES: To describe the health outcomes in older people following hip fracture surgery. DESIGN, SETTING, AND PARTICIPANTS: A naturalistic prospective study of people who had undergone hip fracture surgery undertaken in three specialist inpatient orthopaedic units in Manchester, England, with follow-up for 2 years in primary care. One hundred forty-two people, age 60 and older who had undergone hip fracture surgery of whom 74 were interviewed at follow-up. MEASUREMENTS: Assessment of mood (using the Geriatric Depression Scale and Hospital Anxiety and Depression Scale), cognitive function (Mini-Mental State Examination), pain (Wong-Baker and McGill scales), tests of function (Up and Go Test, Gait Test and Functional Reach), and Sickness Impact Profile. RESULTS: Twenty-six percent of the original group had died by the time of the 2-year follow-up and associated with increasing age, poorer mobility, and higher levels of support. Sixteen percent of the group were found to be depressed, the only robust predictor of this being depression at entry to the study. There was a consistency in the presence or absence of depressive symptoms over the duration of the study. Forty-nine percent were able to walk independently at 2 years. CONCLUSION: The presence of depressive symptoms is associated with poor outcomes at 2 years. Few people recover from, or develop, depression over 2 years.

Understanding the acceptability of e-mental health--attitudes and expectations towards computerised self-help treatments for mental health problems.

BACKGROUND: E-mental health and m-mental health include the use of technology in the prevention, treatment and aftercare of mental health problems. With the economical pressure on mental health services increasing, e-mental health and m-mental health could bridge treatment gaps, reduce waiting times for patients and deliver interventions at lower costs. However, despite the existence of numerous effective interventions, the transition of computerised interventions into care is slow. The aim of the present study was to investigate the acceptability of e-mental health and m-mental health in the general population. METHODS: An advisory group of service users identified dimensions that potentially influence an individual's decision to engage with a particular treatment for mental health problems. A large sample (N = 490) recruited through email, flyers and social media was asked to rate the acceptability of different treatment options for mental health problems on these domains. Results were analysed using repeated measures MANOVA. RESULTS: Participants rated the perceived helpfulness of an intervention, the ability to motivate users, intervention credibility, and immediate access without waiting time as most important dimensions with regard to engaging with a treatment for mental health problems. Participants expected face-to-face therapy to meet their needs on most of these dimensions. Computerised treatments and smartphone applications for mental health were reported to not meet participants' expectations on most domains. However, these interventions scored higher than face-to-face treatments on domains associated with the convenience of access. Overall, participants reported a very low likelihood of using computerised treatments for mental health in the future. CONCLUSIONS: Individuals in this study expressed negative views about computerised self-help intervention and low likelihood of use in the future. To improve the implementation and uptake, policy makers need to improve the public perception of such interventions.

Self-esteem and relapse in schizophrenia: a 5-year follow-up study.

This study investigated the association between an interview-based measure of self-esteem and subsequent clinical outcome in recent-onset schizophrenia. A cohort 5-year follow-up design with retrospective chart assessment of clinical outcomes was used. Relapse rates during 5 years were very high, with 92% of the sample relapsing. Self-esteem consisted of two dimensions, negative evaluation of self (NES) and positive evaluation of self (PES). Survival analysis indicated that high NES was significantly associated with shorter time to relapse; and PES, with longer survival time. The participants with high PES were three times more likely to have delayed relapse; no other covariates were significant. PES seemed to buffer the adverse effects of NES. The results indicate that social cognition in the form of self-evaluation may be implicated in clinical outcome and symptom exacerbation in schizophrenia.This study investigated the association between an interview-based measure of self-esteem and subsequent clinical outcome in recent-onset schizophrenia.

Negative self-appraisals and suicidal behavior among trauma victims experiencing PTSD symptoms: the mediating role of defeat and entrapment.

BACKGROUND: A considerable body of literature has shown a strong association between posttraumatic stress disorder (PTSD) and suicidal behavior but only a limited number of studies have investigated the putative psychological mechanisms underlying suicidal behavior in PTSD. Based on a recent theoretical model of suicide, the Schematic Appraisals Model, the current study aimed to examine whether perceptions of defeat and entrapment mediated the effects of three types of negative self-appraisals (emotion coping, problem solving, and social support) on suicidal behavior among individuals experiencing PTSD symptoms in the past month. METHODS: The sample comprised 56 individuals who had been previously exposed to a traumatic event and reported at least one PTSD symptom in the past month (confirmed through the Posttraumatic Diagnostic Scale). The mediational analyses were conducted using a nonparametric, bootstrapping method. RESULTS: The results showed that defeat and entrapment fully mediated the effect of all three types of self-appraisals on suicidal behavior. When controlling for PTSD symptom severity, defeat and entrapment continued to mediate fully the effect of two types of self-appraisals, namely the perceived ability to control negative emotions (emotion coping) and the perceived ability to cope with difficult situations/problems (problem solving) on suicidal behavior. CONCLUSIONS: The current findings provide support for the Schematic Appraisals Model of Suicide and suggest that both specific types of negative self-appraisals and general perceptions of defeat and entrapment are strongly related to suicidal behavior in those with PTSD. The findings have important clinical implications.

Synesthesia, pseudo-synesthesia, and irritable bowel syndrome.

BACKGROUND AND AIMS: Synesthesia is a sensory disorder where the stimulation of one sensory modality can lead to a reaction in another which would not usually be expected to respond; for instance, someone might see a color on hearing a word such as a day of the week. Disordered perception of sensory information also appears to contribute to the pathophysiology of irritable bowel syndrome (IBS). The purpose of this exploratory study was to ascertain whether these two conditions might be linked in any way. METHODS: Two hundred consecutive IBS outpatients were screened for synesthesia and compared with 200 matched healthy volunteers (controls). Positive responders were tested for two types of synesthesia (grapheme-color and music-color/shape) using a questionnaire which was repeated after 3 months to test for reproducibility. RESULTS: Of the 200 IBS outpatients screened, 26 (13%) patients and six (3%) controls claimed to be synesthetic (P < 0.001). Reproducibility was more variable in IBS patients than controls but despite this variability, 15 (7.5%) patients compared with 5 (2.5%) controls had greater than 75% consistency (P = 0.036), and 19 (9.5%) patients and 6 (3%) controls had greater than 50% consistency (P = 0.012). A reproducibility of less than 50% was observed in seven (3.5%) patients and no controls (0%) (P = 0.015), and these individuals were classified as having pseudo-synesthesia. CONCLUSION: IBS patients clearly differ from controls in terms of claiming to have synesthetic experiences. These results justify additional studies on the relationship between IBS and synesthesia to further understand the neural mechanisms underpinning these two conditions and to establish whether they may be linked.

A meta-analysis of the association between posttraumatic stress disorder and suicidality: the role of comorbid depression.

OBJECTIVE: A considerable number of studies have reported an increased frequency of suicidal behaviors among individuals diagnosed with posttraumatic stress disorder (PTSD). This study aims, first, to provide a comprehensive systematic review and meta-analysis of the association between a PTSD diagnosis and frequency of suicidality and, second, to examine the role of comorbid depression in the association between suicidality and PTSD. METHODS: Searches of Medline (June 2010), EMBASE (June 2010), PsycINFO (June 2010), PILOTS (June 2010), and Web of Science (June 2010) were conducted to identify studies that examined the association between PTSD and suicidality. The studies had to include an effect size of the association between PTSD and suicidality to be included in the meta-analysis. Sixty-three studies were eligible for inclusion in the meta-analysis. Overall and subgroup effect sizes were examined. RESULTS: A highly significant positive association between a PTSD diagnosis and suicidality was found. The PTSD-suicidality association persisted across studies using different measures of suicidality, current and lifetime PTSD, psychiatric and nonpsychiatric samples, and PTSD populations exposed to different types of traumas. Comorbid major depression significantly compounded the risk for suicide in PTSD populations. CONCLUSION: The current meta-analysis provides strong evidence that a PTSD diagnosis is associated with increased suicidality. The crucial role of comorbid major depression in the etiology of suicidality in PTSD is also supported.

Hopelessness, defeat, and entrapment in posttraumatic stress disorder: their association with suicidal behavior and severity of depression.

Research has shown an increased frequency of suicidal behaviors in those with PTSD, but few studies have investigated the factors that underlie the emergence of suicidal behavior in PTSD. Two theories of suicide, the Cry of Pain and the Schematic Appraisal Model of Suicide, propose that feelings of hopelessness, defeat, and entrapment are core components of suicidality. This study aimed to examine the association between suicidal behavior and hopelessness, defeat, and entrapment in trauma victims with and without a PTSD diagnosis. The results demonstrated that hopelessness, defeat, and entrapment were significantly positively associated with suicidal behavior in those with PTSD. Hopelessness and defeat were also significantly positively associated with suicidal behavior in trauma victims without PTSD. In those with PTSD, the relationship between suicidal behavior and hopelessness and entrapment remained significant after controlling for comorbid depression. The findings provide support for the contemporary theories of suicidality and have important clinical implications.

Intelligent real-time therapy: harnessing the power of machine learning to optimise the delivery of momentary cognitive-behavioural interventions.

BACKGROUND: Experience sampling methodology (ESM) [Csikszentmihalyi, M. & Larson, R. (1987). Validity and reliability of the experience-sampling method. Journal of Nervous and Mental Disease, 175(9), 526-536] has been used to elucidate the cognitive-behavioural mechanisms underlying the development and maintenance of complex mental disorders as well as mechanisms involved in resilience from such states. We present an argument for the development of intelligent real-time therapy (iRTT). Machine learning and reinforcement learning specifically may be used to optimise the delivery of interventions by observing and altering the timing of real-time therapies based on ongoing ESM measures. AIMS: The aims of the present article are to outline the principles of iRTT and to consider how it would be applied to complex problems such as suicide prevention. METHODS: Relevant literature was identified through use of PychInfo. RESULTS: iRTT may provide an important and ecologically valid adjunct to traditional CBT, providing a means of balancing population-based data with individual data, thus addressing the "knowledge-practice gap" [Tarrier, N. (2010b). The cognitive and behavioral treatment of PTSD, what is known and what is known to be unknown: How not to fall into the practice gap. Clinical Psychology: Science and Practice, 17(2), 134-143] and facilitating the delivery of interventions in situ, thereby addressing the "therapy-real-world gap". CONCLUSIONS: iRTT may provide a platform for the development of individualised and multifaceted momentary intervention strategies that are ecologically valid and aimed at attenuating pathological pathways to complex mental health problems and amplifying pathways associated with resilience.

Modifying a cognitive behavioral suicide prevention treatment for adults with schizophrenia spectrum disorders in community mental health.

Suicide is among the leading causes of death for adults with schizophrenia spectrum disorders. Given a paucity of evidence-based interventions tailored for psychosis, we sought to modify a promising Cognitive-Behavioral Suicide Prevention for psychosis (CBSPp) treatment for adults in US community mental health (CMH) settings using community-based participatory research methods. This article presents our modification methodology, stakeholder data and scholarly expert input, and CBSPp adaptations prior to future intervention testing. Stakeholder data (n = 25) were collected from clients, providers, and peer advocates in a CMH setting in Michigan. Findings were subsequently presented to a panel of scholarly experts in the fields of suicide and psychosis research, intervention research, and implementation science for input. Emerging themes from stakeholders include logistic, perceptual, and clinical challenges in the process of introducing this treatment in a CMH setting. Consistent with literature, buy-in and support for the delivery of a new treatment emerged as important factors in modifying and implementing CBSPp. A final modification list is presented in this paper and collaborations among stakeholders, researchers, and scholarly experts are essential to navigate psychosocial treatment innovation barriers with an overall goal of improving access, feasibility, and quality of this suicide prevention treatment.

A multi-centre, randomised controlled trial of cognitive therapy to prevent harmful compliance with command hallucinations.

BACKGROUND: Command hallucinations are among the most distressing, high risk and treatment resistant symptoms for people with psychosis; however, currently, there are no evidence-based treatment options available for this group. A cognitive therapy grounded in the principles of the Social Rank Theory, is being evaluated in terms of its effectiveness in reducing harmful compliance with command hallucinations. METHODS/DESIGN: This is a single blind, intention-to-treat, multi-centre, randomized controlled trial comparing Cognitive Therapy for Command Hallucinations + Treatment as Usual with Treatment as Usual alone. Eligible participants have to fulfil the following inclusion criteria: i) ≥16 years; ii) ICD-10 diagnosis of schizophrenia or related disorder; iii) command hallucinations for at least 6 months leading to risk of harm to self or others. Following the completion of baseline assessments, eligible participants will be randomly allocated to either the Cognitive Therapy for Command Hallucinations + Treatment as Usual group or the Treatment as Usual group. Outcome will be assessed at 9 and 18 months post randomization with assessors blind to treatment allocation. The primary outcome is compliance behaviour and secondary outcomes include beliefs about voices' power, distress, psychotic symptoms together with a health economic evaluation. Qualitative interviews with services users will explore the acceptability of Cognitive Therapy for Command Hallucinations. DISCUSSION: Cognitive behaviour therapy is recommended for people with psychosis; however, its focus and evaluation has primarily revolved around the reduction of psychotic symptoms. In this trial, however, the focus of the cognitive behavioural intervention is on individuals' appraisals, behaviour and affect and not necessarily symptoms; this is also reflected in the outcome measures used. If successful, the results will mark a significant breakthrough in the evidence base for service users and clinicians and will provide a treatment option for this group where none currently exist. The trial will open the way for further breakthrough work with the 'high risk' population of individuals with psychosis, which we would intend to pursue. TRIAL REGISTRATION: ISRCTN: ISRCTN62304114.

Trauma and comorbid posttraumatic stress disorder in individuals with schizophrenia and substance abuse.

OBJECTIVES: The aim of this study was to investigate the occurrence of trauma and comorbid posttraumatic stress disorder (PTSD) in dual diagnosis patients and whether the trauma was related to the patient's behavior or illness. METHOD: One hundred ten patients with schizophrenia and comorbid substance or alcohol abuse were assessed for PTSD using self-report and structured interview. Traumatic events were classified as independent or dependent upon the patient's behavior, illness, or symptoms. RESULTS: One hundred patients (91%) reported at least 1 trauma (mean, 4.3). Sixty-three patients (57%) reported a traumatic event that met modified-criterion A for PTSD. Thirty-one patients (28%) met criteria for full PTSD, and 18 (16%) had a trauma directly related to their illness. Patients with PTSD had significantly higher scores on positive psychotic symptoms and depression. CONCLUSIONS: Exposures to traumatic events and comorbid PTSD are high but are inflated by reactions to illness-related events such as hospitalization and psychotic symptoms.

Coping with schizophrenia in forensic services: the needs of relatives.

This study aimed to assess the needs of the relatives of patients in forensic services and to understand their concerns, perceptions, and ability to cope with the symptoms of schizophrenia. The needs of 18 relatives were assessed using the Family Questionnaire (FQ; Quinn et al., Acta Psychiatr Scand 108:290-296, 2003) and the Relatives' Cardinal Needs Schedule (RCNS; Barrowclough et al., Psychol Med 28:531-542, 1998). The FQ revealed that all symptoms were rated as "frequent." The RCNS supported the data from the FQ because the relatives displayed a need for support and information about the mental illness of schizophrenia. Antisocial behavior was rated as the highest cardinal need (83%), with negative symptoms, interpersonal behavior, psychotic symptoms, and affective symptoms also rated as cardinal needs by more than half of the relatives. The relatives have to cope with a range of symptoms and behaviors displayed by the forensic patient, which can be extremely difficult. Forensic services should provide support for families making information about antisocial behavior a priority.

Auditory hallucinations and posttraumatic stress disorder within schizophrenia and substance abuse.

There is a high prevalence of traumatic events within individuals diagnosed with schizophrenia and of auditory hallucinations within individuals diagnosed with posttraumatic stress disorder (PTSD). However, the relationship among the symptoms associated with these disorders remains poorly understood. We conducted a multidimensional assessment of auditory hallucinations within a sample diagnosed with schizophrenia and substance abuse, both with and without comorbid PTSD. The results suggest a rate of comorbid PTSD similar to those reported in other studies. Patients who have comorbid PTSD reported more distressing auditory hallucinations. However, the hallucinations were not more frequent or of longer duration. The need for a multidimensional assessment is supported. The results are discussed within current theoretical accounts of traumatic psychosis.

A functional magnetic resonance imaging paradigm of expressed emotion in schizophrenia.

Chronic exposure to adverse interpersonal environment in schizophrenia is associated with vulnerability to relapse. The construct of expressed emotion (EE) measures the quality of interpersonal environment, of which criticism is a main component. To use functional magnetic resonance imaging and to investigate the neural basis of vulnerability of schizophrenic patients to EE, the effects of critical comments on brain mechanisms in 11 patients with schizophrenia were examined, comparing evoked responses to familiar (key relative) and unfamiliar (matched stranger) critical and neutral commentary. High EE stimuli evoked enhanced activation of brain regions concerned with the processing of aversive social information. Activations in the right BA44, rostral anterior cingulate, middle superior frontal gyrus, bilateral middle frontal gyrus, left temporal pole, left inferior frontal gyrus, and left insula were significantly modulated to familiar criticism. Such a pattern of neural response may represent a putative neural network responsible for mediating High EE in schizophrenia.

Pathways to suicidal behavior in posttraumatic stress disorder.

This study investigated paths to suicidal behavior in 94 civilian participants with chronic posttraumatic stress disorder (PTSD). Two statistical modeling programs, TETRAD II version 2.1 and Mplus 5.21 were used to construct a working model of suicide in PTSD. Two paths to suicidal behavior were identified. In the first path, suicidal behavior was directly associated with greater life impairment, which in turn was associated with poorer occupational and social functioning. In the second path, suicidal behavior was directly associated with depressive symptoms, which in turn were associated with more severe PTSD symptoms. Psychotropic medication, employment status, and threat to life further contributed to the model. The findings suggest that negative perceptions of functional impairment and depression are strongly associated with suicidal behavior in PTSD.

Co-morbid PTSD and suicidality in individuals with schizophrenia and substance and alcohol abuse.

BACKGROUND: Suicide risk is high in schizophrenic patients and is further elevated in dual diagnosis patients. Suicide behaviour is a continuum from ideation, plans to attempts. Exposure to traumatic stress and co-morbid PTSD is elevated in schizophrenic patients. Suicide behaviour is also common in non-psychotic PTSD patients. This study aimed to investigate the effect of trauma and co-morbid PTSD on suicide behaviour in dual diagnosis patients and whether co-morbid PTSD would further elevate suicide risk. METHOD: This was a cross-sectional study in which suicide behaviour was compared in those with and without co-morbid PTSD in 110 patients suffering schizophrenia and alcohol and/or substance abuse. RESULTS: 100 (91%) reported at least one traumatic event with an average of 4.3 events. 31 (28%) patients met criteria for full PTSD. Current suicidal ideation was reported by 39 (35%) and 23 (21%) reported plans and ideation, 69 (63%) reported at least one previous suicide attempt. Suicide behaviour was significantly associated with an increasing number of traumatic events. Suicidality was significantly associated and elevated with co-morbid PTSD. Analysis indicated that the effect of trauma on suicide behaviour appeared to be mediated by hopelessness. CONCLUSIONS: Suicide behaviour was not associated with exposure to trauma per se but was associated with incremental exposure to traumatic experiences. Consistent with the study hypotheses, co-morbid PTSD further adds to the risk of suicide behaviour in an already vulnerable group.
