Catastrophic cognitive appraisals, similar to those in anxiety disorders, are implicated in depersonalisation, a form of dissociation. No scales exist to measure appraisals of dissociative experiences. Dissociation is common in psychosis. Misinterpretations of dissociative experiences may maintain psychotic symptoms. Therefore, assessing appraisals in this context may be valuable.

The primary aim was to develop a measure of key appraisals of dissociation in psychosis. Secondary aims were to test the relationship between appraisals and psychotic experiences (paranoia and hallucinations), and determine whether appraisals explain additional variance in psychotic symptoms above dissociative symptoms.

Fifty items were generated from transcripts of interviews with patients. The measure was developed and psychometrically validated via factor analysis of data from 9902 general population participants and 1026 patients with psychosis. Convergent validity, test–re-test reliability, and internal reliability were assessed. Regression analyses tested relationships with psychotic symptoms.

A 13-item single-factor measure was developed. Factor analysis indicated good model fit [χ2(65) = 247.173, comparative fit index (CFI) = 0.960, root mean square error of approximation (RMSEA) = 0.052]. The scale had good convergent validity with a rumination (non-clinical: r = 0.71; clinical: r = 0.73) and dissociation measure (r = 0.81; r = 0.80), high internal consistency (α = 0.93; α = 0.93), and excellent 1-week test–re-test reliability [intraclass correlation (ICC) = 0.90]. It explained variance in psychotic symptoms (paranoia: 36.4%; hallucinations: 35.0%), including additional variance compared with dissociation alone (paranoia: 5.3%; hallucinations: 2.3%).

The Cognitive Appraisals of Dissociation in Psychosis (CAD-P) measure is a psychometrically robust scale identifying appraisals of dissociative experiences in psychosis and is associated with the presence of psychotic experiences. It is likely to prove useful for clinical assessment and research.

Deficits in social functioning are a core feature of schizophrenia and are influenced by both symptomatic and neurocognitive variables.

In the present study we aimed to determine the reliability and validity of the Portuguese version of the Personal and Social Performance (PSP) scale, and possible correlations with measures of cognitive functioning.

One-hundred and four community and inpatients with schizophrenia were assessed using measures of social functioning and symptom severity alongside measures of executive function, processing speed and verbal memory.

The reliability of the PSP was found to be satisfactory, with a Cronbach's alpha coefficient of 0.789. Inter-rater reliability in the four domains of the PSP varied from 0.430 to 0.954. Low-functioning patients (PSP < 70) were older, had longer duration of illness, were more symptomatic and had worse cognitive performances, as compared to high-functioning patients (PSP ≥ 70). In a regression model, deficits in social functioning were strongly predicted both by symptomatic and neurocognitive variables; these together accounted for up to 62% of the variance.

The present study supports the reliability and validity of the Portuguese language version of the PSP and further supports the original measure. The co-administration of brief cognitive assessments with measures of functioning may lead to more focused interventions, possibly improving outcomes in this group.

The Green et al., Paranoid Thoughts Scale (GPTS) – comprising two 16-item scales assessing ideas of reference (Part A) and ideas of persecution (Part B) – was developed over a decade ago. Our aim was to conduct the first large-scale psychometric evaluation.

In total, 10 551 individuals provided GPTS data. Four hundred and twenty-two patients with psychosis and 805 non-clinical individuals completed GPTS Parts A and B. An additional 1743 patients with psychosis and 7581 non-clinical individuals completed GPTS Part B. Factor analysis, item response theory, and receiver operating characteristic analyses were conducted.

The original two-factor structure of the GPTS had an inadequate model fit: Part A did not form a unidimensional scale and multiple items were locally dependant. A Revised-GPTS (R-GPTS) was formed, comprising eight-item ideas of reference and 10-item ideas of persecution subscales, which had an excellent model fit. All items in the new Reference (a = 2.09–3.67) and Persecution (a = 2.37–4.38) scales were strongly discriminative of shifts in paranoia and had high reliability across the spectrum of severity (a > 0.90). The R-GPTS score ranges are: average (Reference: 0–9; Persecution: 0–4); elevated (Reference: 10–15; Persecution: 5–10); moderately severe (Reference: 16–20; Persecution:11–17); severe (Reference: 21–24; Persecution: 18–27); and very severe (Reference: 25+; Persecution: 28+). Recommended cut-offs on the persecution scale are 11 to discriminate clinical levels of persecutory ideation and 18 for a likely persecutory delusion.

The psychometric evaluation indicated a need to improve the GPTS. The R-GPTS is a more precise measure, has excellent psychometric properties, and is recommended for future studies of paranoia.

Street triage services are now common but the population they serve is poorly understood. We aimed to evaluate a local service to determine the characteristics of those using it and their outcomes in the 90 day period following contact.

We found that there were high levels of service use and that the vast majority of contacts were via telephone rather than in person. Street triage was used by both existing secondary mental health patients and non-patients. Follow-up rates with secondary services were high in the former and low in the latter case.

Services are very busy where they exist and may be replacing traditional crisis services. It is not apparent that they work to increase follow-up among those using them, unless they are already in contact with services. In this service, although there was a joint response model nearly all responses were provided by telephone.

Street triage services are increasingly common and part of standard responses to mental health crises in the community, but little is understood about them. We conducted a national survey of mental health trusts to gather detailed information regarding street triage services alongside a survey of Thames Valley police officers to ascertain their views and experiences.

Triage services are available in most areas of the country and are growing in scope. There is wide variation in levels of funding and modes of operation, including hours covered. Police officers from our survey overwhelmingly support such services and would like to see them expanded.

Mental health crises now form a core part of policing and there are compelling reasons for the support of specialist services. Recent changes to the law have heightened this need, with a requirement for specialist input before a Section 136 is enacted. Those who have experienced triage services report it as less stigmatising and traumatic than a traditional approach, but there remains little evidence on which to base decisions.

None.

Community treatment orders (CTOs) are increasingly embedded into UK practice and their use continues to rise. However, they remain highly controversial. We surveyed psychiatrists to establish their experiences and current opinions of using CTOs and to compare findings with our previous survey conducted in 2010.

The opinions of psychiatrists in the UK have not changed since 2010 in spite of recent evidence questioning the effectiveness of CTOs. Clinical factors (the need for engagement and treatment adherence, and the achievement of adherence and improved insight) remain the most important considerations in initiating and discharging a CTO.

Given the accumulating evidence from research and clinical practice that CTOs do not improve outcomes, it is concerning that psychiatrists' opinions have not altered in response, particularly given the implications for patient care.

We surveyed the views and experiences of all mental health professionals in adult community mental health teams and approved mental health professionals in 2Gether and Oxford Health NHS Foundation Trusts, regarding the use of community treatment orders (CTOs).

A total of 288 surveys were completed (response rate 48%). Forty-eight (83%) psychiatrists and 142 (67%) non-psychiatrist mental health professionals were in favour of CTOs. The decision-making regarding CTOs was overwhelmingly clinically oriented for all professional groups. However, there were significant differences in views between groups regarding the effects of bureaucracy, the infringement of human rights and coercion.

Multidisciplinary team involvement is crucial in decisions regarding CTOs and may protect against idiosyncratic or unhelpful practice. Further training for staff is urgently required and there may be a case for creating small local reference groups that can develop expertise and provide advice and support for clinical teams.

To ascertain the views and experiences of psychiatrists in England and Wales regarding community treatment orders (CTOs). We mailed 1928 questionnaires to members of the Royal College of Psychiatrists.

In total, 566 usable surveys were returned, providing a 29% response rate. Respondents were generally positive about the introduction of the new powers, more so than in previous UK studies. They reported that their decision-making regarding compulsion was based largely on clinical grounds.

In the absence of research evidence or a professional consensus about the use of CTOs, multidisciplinary input in decision-making is essential. Further research and training are urgently needed.

Coercion has usually been equated with legal detention. Non-statutory pressures to adhere to treatment, ‘leverage’, have been identified as widespread in US public mental healthcare. It is not clear if this is so outside the USA.

To measure rates of different non-statutory pressures in distinct clinical populations in England, to test their associations with patient characteristics and compare them with US rates.

Data were collected by a structured interview conducted by independent researchers supplemented by data extraction from case notes.

We recruited a sample of 417 participants from four differing clinical populations. Lifetime experience of leverage was reported in 35% of the sample, 63% in substance misusers, 33% and 30% in the psychosis samples and 15% in the non-psychosis sample. Leverage was associated with repeated hospitalisations, substance misuse diagnosis and lower insight as measured by the Insight and Treatment Attitudes Questionnaire. Housing leverage was the most frequent form (24%). Levels were markedly lower than those reported in the USA.

Non-statutory pressure to adhere to treatment (leverage) is common in English mental healthcare but has received little clinical or research attention. Urgent attention is needed to understand its variation and place in community practice.
