Compared to the general population, people living with schizophrenia spectrum disorders (SSD) are more likely to perpetrate acts of violence. When this happens, family members (informal carers) are most commonly the victims. However, family violence by people with SSD is often a taboo topic and largely neglected within public discourse, research, and clinical domains. Consequently, our understanding of families’ experiences and support needs are limited.

To develop a detailed understanding of the subjective experiences, and impact, of patient violence towards family carers.

Individual semi-structured interviews were held with family carers of adults with SSD and a history of violence perpetration towards their family carer. Interview data were subject to thematic analyses using NVivo software.

Twenty-one UK based carers that were predominately White British (90%) and female (81%) were interviewed. Key themes highlight the range of physical and mental injuries endured by carers following patient violence, and speak to carers’ experiences of suffering, living in a constant state of hypervigilance, as well as social isolation in the context of shame, stigma, and an absence of professional and informal support.

Family violence by people living with SSD can and does happen. Yet, too often, carers are left with no option but to continue supporting their relative in the absence of support, even in contexts where this compromises their own safety. The devastating impact of violence is far-reaching, across all levels of the family-system. The findings highlight the danger of neglecting family violence by people with SSD in research and clinical fields.

The prevalence of ASD among the adult population is estimated to be 1 percent. Despite high rates of anxiety and depression among adults with ASD, treatment methods for these comorbid conditions have not been systematically studies or compared in this patient population. Recently, MBSR and CBT protocols were adapted for adults with ASD and could be excellent candidate therapies for reducing anxiety and depression.

We wanted to study the ability of both treatment methods to reduce anxiety and depression symptoms among adults with ASD, and to determine which therapy is best suited for which patient.

A three-arm RCT among 90 adults with ASD (30 MBSR, 30 CBT, and 30 treatment as usual, (TAU)), was conducted in an outpatient setting with measurements at the start and end of the 14 week treatment period, and at 3 months follow-up. Prior informed consent and medical ethical approval was obtained. Instruments included the hospital anxiety and depressions scale, rumination, irrational belief and mindfulness scales, and an autism symptom checklist.

Preliminary results indicate that both MBSR and CBT lead to a significant reduction in anxiety and depression among adults with ASD. Both MBSR and CBT were superior to TAU. There was no gender or age effect. Effectiveness in relation to patient characteristics will be discussed.

Mindfulness and cognitive behavioral therapies are promising treatment methods to reduce comorbid anxiety and depression in adults with ASD.

We used British national survey data to test specific hypotheses that mood instability 1) is associated with psychosis and individual psychotic phenomena, 2) predicts the later emergence of auditory hallucinations and paranoid ideation, and 3) mediates the link between child sexual abuse and psychosis.

We analysed data from the 2000 and 2007 UK national surveys of psychiatric morbidity (N=8580 and 7403 respectively). The 2000 survey included an 18-month follow-up of a subsample (N=2406). Mood instability was assessed from the Structured Clinical Interview for DSMIV Axis II (SCID-II) questionnaire. Our dependent variables comprised auditory hallucinations, paranoid ideation, the presence of psychosis overall, and a 15-item paranoia scale

Mood Instability was strongly associated in cross-sectional analyses with psychosis (2000 OR: 7.5; 95% CI: I 4.1–13.8; 2007: OR 21.4; CI 9.7–41.2), paranoid ideation (2000: OR: 4.7; CI 4.1–5.4; 2007: OR 5.7; CI 4.9–6.7), auditory hallucinations (2000: OR: 3.4; CI 2.6–4.4; 2007: OR 3.5; CI 2.7–4.7) and paranoia total score (2000: Coefficient: 3.6;CI 3.3–3.9), remaining so after adjustment for current mood state. Baseline mood instability significantly predicted 18-month inceptions of paranoid ideation (OR: 2.3;CI 1.6–3.3) and of auditory hallucinations (OR: 2.6;CI 1.5–4.4). Finally it mediated a third of the total association of child sexual abuse with psychosis and persecutory ideation, and a quarter of that with auditory hallucinations.

Mood instability is a prominent feature of psychotic experience, and may have a role in its genesis. Targeting mood instability could lead to innovative treatments for psychosis.

In cognitive models of adult psychosis, schematic beliefs about the self and others are important vulnerability and maintaining factors, and are therefore targets for psychological interventions. Schematic beliefs have not previously been investigated in children with distressing unusual, or psychotic-like, experiences (UEDs). The aim of this study was firstly to investigate whether a measure of schematic beliefs, originally designed for adults with psychosis, was suitable for children; and secondly, to examine the association of childhood schematic beliefs with internalising and externalising problems and with UEDs.

Sixty-seven children aged 8–14 years, with emotional and behavioural difficulties, completed measures of UEDs, internalising (depression and anxiety), and externalising (conduct and hyperactivity-inattention) problems, together with the Brief Core Schema Scales (BCSS).

The BCSS was readily completed by participants, and scale psychometric properties were good. Children tended to view themselves and others positively. Internalising and externalising problems and UEDs were all associated with negative schematic beliefs; effect sizes were small to medium.

Schematic beliefs in young people can be measured using the BCSS, and negative schematic beliefs are associated with childhood psychopathology and with UEDs. Schematic beliefs may therefore form a useful target in psychological interventions for young people with UEDs.

First-episode psychosis (FEP) is a major life event and can have an adverse impact on the diagnosed individual and their families. The importance of intervening early and providing optimal treatments is widely acknowledged. In comparison to patient groups, literature is scarce on identifying treatment predictors and moderators of caregiver outcomes. This study aimed to identify pre-treatment characteristics predicting and/or moderating carer outcomes, based on data from a multi-element psychosocial intervention to FEP patients and carers (GET-UP PIANO trial).

Carer demography, type of family relationship, patient contact hours, pre-treatment carer burden, patient perceptions of parental caregiving and expressed emotion (EE) were selected, a priori, as potential predictors/moderators of carer burden and emotional distress at 9 months post treatment. Outcomes were analysed separately in mixed-effects random regression models.

Analyses were performed on 260 carers. Only patient perceptions of early maternal criticism predicted reports of lower carer burden at follow-up. However, multiple imputation analysis failed to confirm this result. For treatment moderators: higher levels of carer burden at baseline yielded greater reductions in carer emotional distress at follow-up in the experimental group compared with treatment as usual (TAU). Higher levels of perceived EE moderated greater reductions in carer reports of tension in experimental group, compared with TAU, at follow-up. In younger caregivers (<51 years old), there were greater reductions in levels of worry during the baseline to follow-up period, within the experimental group compared with TAU.

The study failed to identify significant treatment predictors of FEP carer outcomes. However, our preliminary findings suggest that optimal treatment outcomes for carers at first episode might be moderated by younger carer age, and carers reporting higher baseline levels of burden, and where patients perceive higher levels of negative effect from caregivers.

Non-psychotic affective symptoms are important components of psychotic syndromes. They are frequent and are now thought to influence the emergence of paranoia and hallucinations. Evidence supporting this model of psychosis comes from recent cross-fertilising epidemiological and intervention studies. Epidemiological studies identify plausible targets for intervention but must be interpreted cautiously. Nevertheless, causal inference can be strengthened substantially using modern statistical methods.

Directed Acyclic Graphs were used in a dynamic Bayesian network approach to learn the overall dependence structure of chosen variables. DAG-based inference identifies the most likely directional links between multiple variables, thereby locating them in a putative causal cascade. We used initial and 18-month follow-up data from the 2000 British National Psychiatric Morbidity survey (N = 8580 and N = 2406).

We analysed persecutory ideation, hallucinations, a range of affective symptoms and the effects of cannabis and problematic alcohol use. Worry was central to the links between symptoms, with plausible direct effects on insomnia, depressed mood and generalised anxiety, and recent cannabis use. Worry linked the other affective phenomena with paranoia. Hallucinations were connected only to worry and persecutory ideation. General anxiety, worry, sleep problems, and persecutory ideation were strongly self-predicting. Worry and persecutory ideation were connected over the 18-month interval in an apparent feedback loop.

These results have implications for understanding dynamic processes in psychosis and for targeting psychological interventions. The reciprocal influence of worry and paranoia implies that treating either symptom is likely to ameliorate the other.

Cognitive models of adult psychosis propose that negative schematic beliefs (NSBs) mediate the established association between victimisation and psychotic symptoms. In childhood, unusual, or psychotic-like, experiences are associated with bullying (a common form of victimisation) and NSBs. This study tests the mediating role of NSBs in the relationship between bullying and distressing unusual experiences (UEDs) in childhood.

Ninety-four 8–14 year olds referred to community Child and Adolescent Mental Health Services completed self-report assessments of UEDs, bullying, and NSBs about the self (NS) and others (NO).

Both NS and NO were associated with bullying (NS: r = .40, P < .001; NO: r = .33, P = .002), and with UEDs (NS: r = .51, P < .001; NO: r = .43, P < .001). Both NS and NO significantly mediated the relationship between bullying and UEDs (NS: z = 3.15, P = .002; NO: z = 2.35, P = .019).

Children's NSBs may mediate the adverse psychological impact of victimisation, and are appropriate treatment targets for young people with UEDs. Early educational intervention to reduce negative appraisals of the self and others may increase resilience to future adverse experiences and reduce later mental health risk.

Attachment theory proposes that psychological functioning and affect regulations are influenced by the attachment we form with others. Early relationships with parents or caregivers lay the foundations for attachment styles. These styles are proposed to influence how we relate to others during our life can be modified by the relationships and events we experience in our lifespan. A secure attachment style is associated with a capacity to manage distress, comfort with autonomy and the ability to form relationships with others, whereas insecure attachment can lead to dysfunctional relationships, emotional and behaviour avoidance. Attachment theory provides a useful framework to inform our understanding of relationship difficulties in people with psychosis. This paper aims to complement recent systematic reviews by providing an overview of attachment theory, its application to psychosis, including an understanding of measurement issues and the clinical implications offered.

A narrative review was completed of the measures of attachment and parental bonding in psychosis. Its clinical implications are also discussed. The paper also explores the link between insecure attachment styles and illness course, social functioning and symptomatology. The following questions are addressed: What are the key attachment measures that have been used within the attachment and psychosis literature? What are the results of studies that have measured attachment or parental bonding in psychosis and what clinical implications can we derive from it? What are some of the key questions for future research from these findings in relation to the onset of psychosis research field?

The most commonly used measures of attachment in psychosis research are reviewed. Self-report questionnaires and semi-structured interviews have mainly been used to examine attachment styles in adult samples and in recent years comprise a measure specifically developed for a psychosis group. The review suggests that insecure attachment styles are common in psychosis samples. Key relationships were observed between insecure, avoidant and anxious attachment styles and psychosis development, expression and long-term outcome.

Attachment theory can provide a useful framework to facilitate our understanding of interpersonal difficulties in psychosis that may predate its onset and impact on observed variability in outcomes, including treatment engagement. Greater attention should be given to the assessment of attachment needs and to the development of interventions that seek to compensate for these difficulties. However, further investigations are required on specifying the exact mechanisms by which specific attachment styles impact on the development of psychosis and its course.

For people with psychosis, contact with informal caregivers is an important source of social support, associated with recovery, and with better outcomes following individual cognitive therapy (CBTp). In this study, we tested whether increased flexibility in delusional thinking, an established predictor of positive outcome following CBTp, was a possible mechanism underlying this effect.

219 participants with delusions (mean age 38 years; 71% male; 75% White) were grouped according to the presence of a caregiver (37% with a caregiver) and caregiver level of expressed emotion (High/Low EE, 64% Low). Delusional belief flexibility was compared between groups, controlling for interpersonal functioning, severity of psychotic symptoms, and other hypothesised outcome predictors.

Participants with caregivers were nearly three times more likely than those without to show flexibility (OR = 2.7, 95% CI 1.5 to 5.0, p = 0.001), and five times more likely if the caregiving relationship was Low EE (OR = 5.0, 95% CI 2.0–13.0, p = 0.001). ORs remained consistent irrespective of controlling for interpersonal functioning and other predictors of outcome.

This is the first evidence that having supportive caregiving relationships is associated with a specific cognitive attribute in people with psychosis, suggesting a potential cognitive mechanism by which outcomes following CBTp, and perhaps more generally, are improved by social support.

Psychotic phenomena appear to form a continuum with normal experience and beliefs, and may build on common emotional interpersonal concerns.

We tested predictions that paranoid ideation is exponentially distributed and hierarchically arranged in the general population, and that persecutory ideas build on more common cognitions of mistrust, interpersonal sensitivity and ideas of reference.

Items were chosen from the Structured Clinical Interview for DSM-IV Axis II Disorders (SCID-II) questionnaire and the Psychosis Screening Questionnaire in the second British National Survey of Psychiatric Morbidity (n = 8580), to test a putative hierarchy of paranoid development using confirmatory factor analysis, latent class analysis and factor mixture modelling analysis.

Different types of paranoid ideation ranged in frequency from less than 2% to nearly 30%. Total scores on these items followed an almost perfect exponential distribution (r = 0.99). Our four a priori first-order factors were corroborated (interpersonal sensitivity; mistrust;ideas of reference; ideas of persecution). These mapped onto four classes of individual respondents:a rare, severe, persecutory class with high endorsement of all item factors, including persecutory ideation; a quasi-normal class with infrequent endorsement of interpersonal sensitivity, mistrust and ideas of reference, and no ideas of persecution; and two intermediate classes, characterised respectively by relatively high endorsement of items relating to mistrust and to ideas of reference.

The paranoia continuum has implications for the aetiology, mechanisms and treatment of psychotic disorders, while confirming the lack of a clear distinction from normal experiences and processes.

Being physically assaulted is known to increase the risk of the occurrence of post-traumatic stress disorder (PTSD) symptoms but it may also skew judgements about the intentions of other people. The objectives of the study were to assess paranoia and PTSD after an assault and to test whether theory-derived cognitive factors predicted the persistence of these problems.

At 4 weeks after hospital attendance due to an assault, 106 people were assessed on multiple symptom measures (including virtual reality) and cognitive factors from models of paranoia and PTSD. The symptom measures were repeated 3 and 6 months later.

Factor analysis indicated that paranoia and PTSD were distinct experiences, though positively correlated. At 4 weeks, 33% of participants met diagnostic criteria for PTSD, falling to 16% at follow-up. Of the group at the first assessment, 80% reported that since the assault they were excessively fearful of other people, which over time fell to 66%. Almost all the cognitive factors (including information-processing style during the trauma, mental defeat, qualities of unwanted memories, self-blame, negative thoughts about self, worry, safety behaviours, anomalous internal experiences and cognitive inflexibility) predicted later paranoia and PTSD, but there was little evidence of differential prediction.

Paranoia after an assault may be common and distinguishable from PTSD but predicted by a strikingly similar range of factors.

Violent behaviour has been associated with presence of certain mental disorders, most notably antisocial personality disorder (ASPD) and schizophrenia, childhood abuse, and multiple brain abnormalities. This study examined for the first time, to the authors’ knowledge, the role of psychosocial deprivation (PSD), including childhood physical and sexual abuse, in structural brain volumes of violent individuals with ASPD or schizophrenia.

Fifty-six men (26 with ASPD or schizophrenia and a history of serious violence, 30 non-violent) underwent magnetic resonance imaging and were assessed on PSD. Stereological volumetric brain ratings were examined for group differences and their association with PSD ratings. PSD-brain associations were examined further using voxel-based-morphometry.

The findings revealed: reduced thalamic volume in psychosocially-deprived violent individuals, relative to non-deprived violent individuals and healthy controls; negative association between thalamic volume and abuse ratings (physical and sexual) in violent individuals; and trend-level negative associations between PSD and hippocampal and prefrontal volumes in non-violent individuals. The voxel-based-morphometry analysis detected a negative association between PSD and localised grey matter volumes in the left inferior frontal region across all individuals, and additionally in the left middle frontal and precentral gyri in non-violent individuals.

Violent mentally-disordered individuals with PSD, relative to those with no or minimal PSD, suffer from an additional brain deficit, i.e., reduced thalamic volume; this may affect sensory information processing, and have implications for management, of these individuals. PSD may have a stronger relationship with volumetric loss of stress-linked regions, namely the frontal cortex, in non-violent individuals.

There is evidence that patients with schizophrenia benefit from standard cognitive behaviour therapy (CBT) only if active techniques are used (‘full therapy’). By contrast, attending sessions but not proceeding beyond engagement and assessment strategies (‘partial therapy’), or simply not attending sessions (‘no therapy’), is not associated with better outcomes. The factors leading to full therapy are unknown. We hypothesized that patients' initial ideas about the nature and extent of their problems would predict use of CBT. A match between patients' views of their problems and the principles underlying treatment would lead to better outcomes.

Ninety-two patients with a recent relapse of psychosis completed the Illness Perception Questionnaire (IPQ) before receiving CBT. We examined whether their illness perceptions predicted the take-up of therapy.

Patients who did not attend sessions believed their problems would not last as long as those who attended them. Those who attended sessions but did not proceed to full therapy had a lower sense of control over their problems and a more biological view of their causes. Patients who took up full therapy were more likely to attribute the cause of their problems to their personality and state of mind. The take-up of therapy was predicted neither by levels of psychiatric symptoms nor by insight.

People with psychosis who have psychologically orientated views of their problems, including the potential to gain control over them, may be more likely to engage fully and do well with standard CBT for psychosis, irrespective of the severity of their problems.

Previous studies have suggested that beliefs about voices mediate the relationship between actual voice experience and behavioural and affective response.

We investigated beliefs about voice power (omnipotence), voice intent (malevolence/benevolence) and emotional and behavioural response (resistance/engagement) using the Beliefs About Voices Questionnaire – Revised (BAVQ-R) in 46 voice hearers. Distress was assessed using a wide range of measures: voice-related distress, depression, anxiety, self-esteem and suicidal ideation. Voice topography was assessed using measures of voice severity, frequency and intensity. We predicted that beliefs about voices would show a stronger association with distress than voice topography.

Omnipotence had the strongest associations with all measures of distress included in the study whereas malevolence was related to resistance, and benevolence to engagement. As predicted, voice severity, frequency and intensity were not related to distress once beliefs were accounted for.

These results concur with previous findings that beliefs about voice power are key determinants of distress in voice hearers, and should be targeted specifically in psychological interventions.

Meta-analyses show that cognitive behaviour therapy for psychosis (CBT-P) improves distressing positive symptoms. However, it is a complex intervention involving a range of techniques. No previous study has assessed the delivery of the different elements of treatment and their effect on outcome. Our aim was to assess the differential effect of type of treatment delivered on the effectiveness of CBT-P, using novel statistical methodology.

The Psychological Prevention of Relapse in Psychosis (PRP) trial was a multi-centre randomized controlled trial (RCT) that compared CBT-P with treatment as usual (TAU). Therapy was manualized, and detailed evaluations of therapy delivery and client engagement were made. Follow-up assessments were made at 12 and 24 months. In a planned analysis, we applied principal stratification (involving structural equation modelling with finite mixtures) to estimate intention-to-treat (ITT) effects for subgroups of participants, defined by qualitative and quantitative differences in receipt of therapy, while maintaining the constraints of randomization.

Consistent delivery of full therapy, including specific cognitive and behavioural techniques, was associated with clinically and statistically significant increases in months in remission, and decreases in psychotic and affective symptoms. Delivery of partial therapy involving engagement and assessment was not effective.

Our analyses suggest that CBT-P is of significant benefit on multiple outcomes to patients able to engage in the full range of therapy procedures. The novel statistical methods illustrated in this report have general application to the evaluation of heterogeneity in the effects of treatment.
