Article
The current research explored the prevalence of stressful events in a forensic hospital setting, and their impact on staff. A systematic review of the literature on responses following exposure to extreme stress comprised 46 articles. This was followed by a Delphi study of professionals based in a forensic hospital (n = 43) to explore views on the...
Article
There is an association between childhood trauma and the development of psychosis in adulthood and a treatment recommended to reduce the symptoms of trauma is Eye Movement Desensitisation and Reprocessing (EMDR). Studies of EMDR in adults with psychotic experiences and a history of trauma have shown encouraging results. As psychosis is a core featu...

Memory is facilitated by reflecting upon, or revisiting, the environment in which information was encoded. We investigated these “context reinstatement” (CR) techniques to improve the effectiveness of facial composites – visual likenesses of a perpetrator’s face constructed by eyewitnesses. Participant-constructors viewed a face and, after a one-da...
Article
DasThema der Intensivbetreuungen in der stationären psychiatrischen Versorgung ist in den letzten Jahren immer mehr in den Blick auch der Pflegewissenschaft geraten. Auch im deutschsprachigen Raum ist eine zunehmende Beschäftigung mit dem Thema zu verzeichnen. Trotz einer Zunahme des Interesses an diesem Thema blei- ben in der Praxis Fragen bestehe...
Article
A measure for the assessment of self-injurious behavior is developed. Commencing with a Delphi composed of 33 experts: detached experts (academics), experts by exposure (staff), and experts by experience (patients), the Theory-driven Measure of Self-Injurious Behavior Engagement is outlined. This is then examined in two samples: high-secure psychia...
Article
The current study examined the psychopathy-aggression relationship by considering different forms of aggression, including aggressive motivation. Emotions were explored as useful in understanding any emerging relationship, notably those consistent with detachment and sensitivity/poor regulation. In three studies, involving non-offending samples (St...

Aims and method To investigate the percentage of patients who commenced smoking after transferring out of a non-smoking forensic psychiatric unit, the corresponding clozapine dose adjustments, the effects on plasma clozapine/norclozapine concentrations and observed changes in mental state. We reviewed the notes and plasma clozapine/norclozapine con...
Article
Full-text available
Introduction: Supportive observations are common in mental health care but there are no guidelines on best practice or what should be documented in observations records. Aim: To develop expert consensus on the important aspects of patient presentation that inform clinical decision-making about observations, and to develop a recording tool from t...
Article
Full-text available
Background: Clozapine-induced hypersalivation (CIH) is a common side effect of clozapine treatment and is disliked by clozapine patients, potentially threatening adherence to clozapine treatment. We proposed a trial of alternative medications, hyoscine and glycopyrrolate, for the treatment of CIH and the primary objective of the feasibility study...
Article
Purpose: The contribution of environmental and organisational factors in predicting security incidents within a high secure male psychiatric setting is considered using a series of connected studies; a systematic literature review comprising 41 studies and five inquiries (Study 1) to identify core themes of likely importance; application of these...
Article
Full-text available
Three preliminary and linked studies investigate the impact of making alterations to factors considered relevant to engaging in and experiencing intra-group aggression (bullying) among adult male patients detained in a single secure forensic hospital. Study one (n = 44) outlines the institutional factors, attitudes towards bullying and environmenta...
Article
Full-text available
The current study explored the impact of nursing staff members' interpersonal style and attitudes toward coercion on the management of their professional boundaries. Researchers predicted that a combination of a particular interpersonal style, a specific attitude toward coercion, and self-reported engagement in boundary-crossing behavior would be a...

Full-text available
Aims and method We explored the prevalence and use of constant supportive observations (CSO) in high, medium and low secure in-patient services in a single National Health Service (NHS) mental health trust. From clinical records, we extracted data on the length of time of CSO, the reason for the initiation of CSO and associated adverse incidents fo...
Article
Full-text available
Background The at-risk mental state (ARMS) describes individuals at high risk of developing schizophrenia or psychosis. The use of antipsychotics in this population is not supported, because most individuals with ARMS are unlikely to develop psychosis. Anti-inflammatory treatments and polyunsaturated fatty acids (PUFAs) may have some beneficial eff...
Article
This study examined the impact of an intensive inpatient violent offender treatment programme, Life Minus Violence-Enhanced (LMV-E), on intermediary treatment targets, risk for violence, and aggressive behaviour during treatment in a sample of male mentally disordered offenders. Using quasi-experimental design, offenders who completed LMV-E and a c...
Article
Full-text available
Background: Clozapine is the only medication licensed for the treatment of resistant schizophrenia in the UK. Although efficacious, a common and unpopular side effect of clozapine treatment is clozapine-induced hypersalivation (CIH), which can contribute to non-adherence. The standard treatment for CIH in the UK is hyoscine hydrobromide but this m...
Article
Objective: The current paper aims to examine the association between self-reported sleep quality and quantity and how these relate to aggression motivation and hostile cognition in a male prisoner sample. The cognitive component of sleep, namely perception, is consequently a variable of particular interest and one neglected by previous research....

Background Risk assessment instruments have become a preferred means for predicting future aggression, claiming to predict long-term aggression risk. Aims To investigate the predictive value over 12 months and 4 years of two commonly applied instruments (Historical, Clinical and Risk Management - 20 (HCR-20) and Violence Risk Appraisal Guide (VRAG...
Article
We investigated the relationship between a change in sleep quality and facial emotion recognition accuracy in a group of mentally-disordered inpatients at a secure forensic psychiatric unit. Patients whose sleep improved over time also showed improved facial emotion recognition while patients who showed no sleep improvement showed no change in emot...
Article
Full-text available
Patients prescribed clozapine were surveyed to assess (a) the effects, both positive and adverse, and overall satisfaction with clozapine in comparison to previously prescribed antipsychotics and (b) the relative significance of effects experienced, both positive and adverse, in terms of impact on subjective well-being. A total of 56 male patients...

Purpose – From 2012, all high-secure forensic mental health services in England began operating a policy of confining patients to their locked bedrooms overnight to increase service efficiency and reduce costs. The purpose of this paper is to assess the views of staff and patients concerning the policy and examine the specific impact of the policy...

Trying to remember something now typically improves your ability to remember it later. However, after watching a video of a simulated bank robbery, participants who verbally described the robber were 25% worse at identifying the robber in a lineup than were participants who instead listed U.S. states and capitals—this has been termed the “verbal ov...

Article
Mate-choice copying is shown when women imitate the mate-choice preferences of other women. We propose that the preferences of women with a pleasant character should be more influential than those of women with an unpleasant character and further suggest that this should apply only when the female demonstrates active interest in the male, rather th...

Standard context-dependent memory studies have shown that when information is encoded in a certain environmental context (EC), recall performance is weakened when retrieval occurs in a different, rather than the same, EC. Here, we show that this context-dependent forgetting can be eliminated using mental imagery at encoding. In two studies, partici...

Women appear to exhibit a subtle reluctance to engage in long-term relationships with physically attractive, high-status men. We propose that this bias away from men of very high market value is based on fear that these males may desert a relationship and also on the comparative self-perceived market value of the women. Therefore, interpersonal tru...
Article
Lavender odour is commonly used to alleviate mild anxiety. Double blind studies are difficult to conduct with odours, and there are few reliable investigations of lavender's efficacy. Orally administered lavender capsules (placebo, 100, 200 microl) were tested in a randomised between-subjects (n = 97) double-blind study. Film clips were used to eli...

Lavender odour is commonly used to alleviate mild anxiety; but there are few reliable investigations of its efficacy because double blind studies are difficult to conduct with odours. The effects of lavender capsules (placebo, 100µl, 200µl) orally administered were tested in a randomised between subjects (n=97) double blind laboratory study. Film c...

Olfactory conditioning effects have been widely demonstrated in the animal literature but more seldom in human populations and rarely of consciously controlled human behaviors. Building upon previous work on negative performance, we report the first experimental evidence that odors can be used effectively in a classical conditioning paradigm to pos...
Article
Empirical evidence concerning human mate-choice preferences suggests that females should select partners on the basis of cues to genetic quality and/or ability to contribute resources to childcare. Paradoxically, while high levels of both factors should be an attractive combination to females, they might also dissuade females from entering into a r...

It is well established that height influences the perceived character of men but very little evidence exists that the same influences of height exist for women. To investigate the effects of female height on perception of their character, we used a novel technique of digitally altering the perceived height of two women depicted in photographs such...

The Proust phenomenon is an enduring piece of folk wisdom that asserts that odors are particularly powerful autobiographical memory cues. We provide a more formal exposition of this phenomenon and test it in two experiments, using a novel double-cuing methodology designed to negate less interesting explanations. In both studies, recall of an autobi...

The autobiographical memory bump is an increase in the frequency of reported autobiographical memories (AMs) from a particular age range, and has been reported by numerous investigators (for reviews, see Conway, M. A. & Rubin, D. C. (1993). The structure of autobiographical memory. In A. F. Collins, S. E. Gathercole, M. A. Conway & P. E. Morris, Th...
Article
Full-text available
Folk wisdom dictates that odours are especially powerful reminders of autobiographical experience, an effect which has become known as the Proust phenomenon. This paper reviews the relevant literature to determine whether there is any substantive evidence to support this view. Different methodologies have been adopted in addressing this issue, but...
