Service variation in baseline variables and prediction of risk in a randomised controlled trial of psychological treatment in repeated parasuicide: the POPMACT Study

Psychological interventions for antisocial personality disorder

BACKGROUND

Antisocial personality disorder (AsPD) is associated with poor mental health, criminality, substance use and relationship difficulties. This review updates Gibbon 2010 (previous version of the review).

OBJECTIVES

To evaluate the potential benefits and adverse effects of psychological interventions for adults with AsPD.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, 13 other databases and two trials registers up to 5 September 2019. We also searched reference lists and contacted study authors to identify studies.

SELECTION CRITERIA

Randomised controlled trials of adults, where participants with an AsPD or dissocial personality disorder diagnosis comprised at least 75% of the sample randomly allocated to receive a psychological intervention, treatment-as-usual (TAU), waiting list or no treatment. The primary outcomes were aggression, reconviction, global state/functioning, social functioning and adverse events.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane.

MAIN RESULTS

This review includes 19 studies (eight new to this update), comparing a psychological intervention against TAU (also called 'standard Maintenance'(SM) in some studies). Eight of the 18 psychological interventions reported data on our primary outcomes. Four studies focussed exclusively on participants with AsPD, and 15 on subgroups of participants with AsPD. Data were available from only 10 studies involving 605 participants. Eight studies were conducted in the UK and North America, and one each in Iran, Denmark and the Netherlands. Study duration ranged from 4 to 156 weeks (median = 26 weeks). Most participants (75%) were male; the mean age was 35.5 years. Eleven studies (58%) were funded by research councils. Risk of bias was high for 13% of criteria, unclear for 54% and low for 33%. Cognitive behaviour therapy (CBT) + TAU versus TAU One study (52 participants) found no evidence of a difference between CBT + TAU and TAU for physical aggression (odds ratio (OR) 0.92, 95% CI 0.28 to 3.07; low-certainty evidence) for outpatients at 12 months post-intervention. One study (39 participants) found no evidence of a difference between CBT + TAU and TAU for social functioning (mean difference (MD) -1.60 points, 95% CI -5.21 to 2.01; very low-certainty evidence), measured by the Social Functioning Questionnaire (SFQ; range = 0-24), for outpatients at 12 months post-intervention. Impulsive lifestyle counselling (ILC) + TAU versus TAU One study (118 participants) found no evidence of a difference between ILC + TAU and TAU for trait aggression (assessed with Buss-Perry Aggression Questionnaire-Short Form) for outpatients at nine months (MD 0.07, CI -0.35 to 0.49; very low-certainty evidence). One study (142 participants) found no evidence of a difference between ILC + TAU and TAU alone for the adverse event of death (OR 0.40, 95% CI 0.04 to 4.54; very low-certainty evidence) or incarceration (OR 0.70, 95% CI 0.27 to 1.86; very low-certainty evidence) for outpatients between three and nine months follow-up. Contingency management (CM) + SM versus SM One study (83 participants) found evidence that, compared to SM alone, CM + SM may improve social functioning measured by family/social scores on the Addiction Severity Index (ASI; range = 0 (no problems) to 1 (severe problems); MD -0.08, 95% CI -0.14 to -0.02; low-certainty evidence) for outpatients at six months. 'Driving whilst intoxicated' programme (DWI) + incarceration versus incarceration One study (52 participants) found no evidence of a difference between DWI + incarceration and incarceration alone on reconviction rates (hazard ratio 0.56, CI -0.19 to 1.31; very low-certainty evidence) for prisoner participants at 24 months. Schema therapy (ST) versus TAU One study (30 participants in a secure psychiatric hospital, 87% had AsPD diagnosis) found no evidence of a difference between ST and TAU for the number of participants who were reconvicted (OR 2.81, 95% CI 0.11 to 74.56, P = 0.54) at three years. The same study found that ST may be more likely to improve social functioning (assessed by the mean number of days until patients gain unsupervised leave (MD -137.33, 95% CI -271.31 to -3.35) compared to TAU, and no evidence of a difference between the groups for overall adverse events, classified as the number of people experiencing a global negative outcome over a three-year period (OR 0.42, 95% CI 0.08 to 2.19). The certainty of the evidence for all outcomes was very low. Social problem-solving (SPS) + psychoeducation (PE) versus TAU One study (17 participants) found no evidence of a difference between SPS + PE and TAU for participants' level of social functioning (MD -1.60 points, 95% CI -5.43 to 2.23; very low-certainty evidence) assessed with the SFQ at six months post-intervention. Dialectical behaviour therapy versus TAU One study (skewed data, 14 participants) provided very low-certainty, narrative evidence that DBT may reduce the number of self-harm days for outpatients at two months post-intervention compared to TAU. Psychosocial risk management (PSRM; 'Resettle') versus TAU One study (skewed data, 35 participants) found no evidence of a difference between PSRM and TAU for a number of officially recorded offences at one year after release from prison. It also found no evidence of difference between the PSRM and TAU for the adverse event of death during the study period (OR 0.89, 95% CI 0.05 to 14.83, P = 0.94, 72 participants (90% had AsPD), 1 study, very low-certainty evidence).

AUTHORS' CONCLUSIONS

There is very limited evidence available on psychological interventions for adults with AsPD. Few interventions addressed the primary outcomes of this review and, of the eight that did, only three (CM + SM, ST and DBT) showed evidence that the intervention may be more effective than the control condition. No intervention reported compelling evidence of change in antisocial behaviour. Overall, the certainty of the evidence was low or very low, meaning that we have little confidence in the effect estimates reported. The conclusions of this update have not changed from those of the original review, despite the addition of eight new studies. This highlights the ongoing need for further methodologically rigorous studies to yield further data to guide the development and application of psychological interventions for AsPD and may suggest that a new approach is required.

Psychological therapies for people with borderline personality disorder

BACKGROUND

Over the decades, a variety of psychological interventions for borderline personality disorder (BPD) have been developed. This review updates and replaces an earlier review (Stoffers-Winterling 2012).

OBJECTIVES

To assess the beneficial and harmful effects of psychological therapies for people with BPD.

SEARCH METHODS

In March 2019, we searched CENTRAL, MEDLINE, Embase, 14 other databases and four trials registers. We contacted researchers working in the field to ask for additional data from published and unpublished trials, and handsearched relevant journals. We did not restrict the search by year of publication, language or type of publication.

SELECTION CRITERIA

Randomised controlled trials comparing different psychotherapeutic interventions with treatment-as-usual (TAU; which included various kinds of psychotherapy), waiting list, no treatment or active treatments in samples of all ages, in any setting, with a formal diagnosis of BPD. The primary outcomes were BPD symptom severity, self-harm, suicide-related outcomes, and psychosocial functioning. There were 11 secondary outcomes, including individual BPD symptoms, as well as attrition and adverse effects.

DATA COLLECTION AND ANALYSIS

At least two review authors independently selected trials, extracted data, assessed risk of bias using Cochrane's 'Risk of bias' tool and assessed the certainty of the evidence using the GRADE approach. We performed data analysis using Review Manager 5 and quantified the statistical reliability of the data using Trial Sequential Analysis.

MAIN RESULTS

We included 75 randomised controlled trials (4507 participants), predominantly involving females with mean ages ranging from 14.8 to 45.7 years. More than 16 different kinds of psychotherapy were included, mostly dialectical behaviour therapy (DBT) and mentalisation-based treatment (MBT). The comparator interventions included treatment-as-usual (TAU), waiting list, and other active treatments. Treatment duration ranged from one to 36 months. Psychotherapy versus TAU Psychotherapy reduced BPD symptom severity, compared to TAU; standardised mean difference (SMD) -0.52, 95% confidence interval (CI) -0.70 to -0.33; 22 trials, 1244 participants; moderate-quality evidence. This corresponds to a mean difference (MD) of -3.6 (95% CI -4.4 to -2.08) on the Zanarini Rating Scale for BPD (range 0 to 36), a clinically relevant reduction in BPD symptom severity (minimal clinical relevant difference (MIREDIF) on this scale is -3.0 points). Psychotherapy may be more effective at reducing self-harm compared to TAU (SMD -0.32, 95% CI -0.49 to -0.14; 13 trials, 616 participants; low-quality evidence), corresponding to a MD of -0.82 (95% CI -1.25 to 0.35) on the Deliberate Self-Harm Inventory Scale (range 0 to 34). The MIREDIF of -1.25 points was not reached. Suicide-related outcomes improved compared to TAU (SMD -0.34, 95% CI -0.57 to -0.11; 13 trials, 666 participants; low-quality evidence), corresponding to a MD of -0.11 (95% CI -0.19 to -0.034) on the Suicidal Attempt Self Injury Interview. The MIREDIF of -0.17 points was not reached. Compared to TAU, psychotherapy may result in an improvement in psychosocial functioning (SMD -0.45, 95% CI -0.68 to -0.22; 22 trials, 1314 participants; low-quality evidence), corresponding to a MD of -2.8 (95% CI -4.25 to -1.38), on the Global Assessment of Functioning Scale (range 0 to 100). The MIREDIF of -4.0 points was not reached. Our additional Trial Sequential Analysis on all primary outcomes reaching significance found that the required information size was reached in all cases. A subgroup analysis comparing the different types of psychotherapy compared to TAU showed no clear evidence of a difference for BPD severity and psychosocial functioning. Psychotherapy may reduce depressive symptoms compared to TAU but the evidence is very uncertain (SMD -0.39, 95% CI -0.61 to -0.17; 22 trials, 1568 participants; very low-quality evidence), corresponding to a MD of -2.45 points on the Hamilton Depression Scale (range 0 to 50). The MIREDIF of -3.0 points was not reached. BPD-specific psychotherapy did not reduce attrition compared with TAU. Adverse effects were unclear due to too few data. Psychotherapy versus waiting list or no treatment Greater improvements in BPD symptom severity (SMD -0.49, 95% CI -0.93 to -0.05; 3 trials, 161 participants), psychosocial functioning (SMD -0.56, 95% CI -1.01 to -0.11; 5 trials, 219 participants), and depression (SMD -1.28, 95% CI -2.21 to -0.34, 6 trials, 239 participants) were observed in participants receiving psychotherapy versus waiting list or no treatment (all low-quality evidence). No evidence of a difference was found for self-harm and suicide-related outcomes. Individual treatment approaches DBT and MBT have the highest numbers of primary trials, with DBT as subject of one-third of all included trials, followed by MBT with seven RCTs. Compared to TAU, DBT was more effective at reducing BPD severity (SMD -0.60, 95% CI -1.05 to -0.14; 3 trials, 149 participants), self-harm (SMD -0.28, 95% CI -0.48 to -0.07; 7 trials, 376 participants) and improving psychosocial functioning (SMD -0.36, 95% CI -0.69 to -0.03; 6 trials, 225 participants). MBT appears to be more effective than TAU at reducing self-harm (RR 0.62, 95% CI 0.49 to 0.80; 3 trials, 252 participants), suicidality (RR 0.10, 95% CI 0.04, 0.30, 3 trials, 218 participants) and depression (SMD -0.58, 95% CI -1.22 to 0.05, 4 trials, 333 participants). All findings are based on low-quality evidence. For secondary outcomes see review text.

AUTHORS' CONCLUSIONS

Our assessments showed beneficial effects on all primary outcomes in favour of BPD-tailored psychotherapy compared with TAU. However, only the outcome of BPD severity reached the MIREDIF-defined cut-off for a clinically meaningful improvement. Subgroup analyses found no evidence of a difference in effect estimates between the different types of therapies (compared to TAU) . The pooled analysis of psychotherapy versus waiting list or no treatment found significant improvement on BPD severity, psychosocial functioning and depression at end of treatment, but these findings were based on low-quality evidence, and the true magnitude of these effects is uncertain. No clear evidence of difference was found for self-harm and suicide-related outcomes. However, compared to TAU, we observed effects in favour of DBT for BPD severity, self-harm and psychosocial functioning and, for MBT, on self-harm and suicidality at end of treatment, but these were all based on low-quality evidence. Therefore, we are unsure whether these effects would alter with the addition of more data.

Psychological treatment for personality disorders

There is encouraging evidence that some patients with personality disorder are treatable. Psychotherapeutic interventions show promise, although interpretation of the literature is problematic: the number of patients in most trials is small, outcome measures are questionable, follow-up is limited, and treatments are multifaceted, complex interventions in which the effective components are unclear. The evidence base can be assessed according to efficacy and generalisability, and when both are taken into account the best verification is for psychodynamic therapy. However, there is inadequate evidence to make specific recommendations for any particular therapy.

Deliberate Self-Harm: Have We Scratched the Surface?

This article presents the current state of knowledge in deliberate-self harm (DSH). DSH presents as a comorbidity with a number of personality disorders and psychopathologies, but is also relatively common in the psychologically healthy population. Over the past 10 years, attention has shifted from the investigation of DSH as a cardinal or comorbid symptom of psychopathology to an attempt to understand the behaviour itself, without reference to other psychopathological processes. It is argued that this development in understanding the aetiology of DSH has not been matched by developments in treatment or management of DSH, with the majority of treatment programs targeting larger syndromes of which DSH is a symptom. Treatment regimes aimed at reducing DSH appear to be either untested or demonstrably unsuccessful.

Psychological and educational interventions for preventing depression in children and adolescents

BACKGROUND

Depression is common in young people, has a marked negative impact and is associated with self-harm and suicide. Preventing its onset would be an important advance in public health.  

OBJECTIVES

To determine whether psychological or educational interventions, or both, are effective in preventing the onset of depressive disorder in children and adolescents.

SEARCH METHODS

The Cochrane Depression, Anxiety and Neurosis Review Group's trials registers (CCDANCTR) were searched at the editorial base in July 2010. Update searches of MEDLINE, EMBASE, PsycINFO and ERIC were conducted by the authors in September 2009. Conference abstracts, reference lists of included studies and reviews were searched and experts in the field contacted.

SELECTION CRITERIA

Randomised controlled trials of psychological or educational prevention programmes, or both, compared with placebo, any comparison intervention, or no intervention for young people aged 5 to 19 years-old, who did not currently meet diagnostic criteria for depression or who were below the clinical range on standardised, validated, and reliable rating scales of depression, or both, were included.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed studies for inclusion and rated their quality. Sample sizes were adjusted to take account of cluster designs and multiple comparisons. We contacted study authors for additional information where needed. 

MAIN RESULTS

Fifty-three studies including 14,406 participants were included in the analysis. There were only six studies with clear allocation concealment, participants and assessors were mostly not blind to the intervention or blinding was unclear so that the overall risk of bias was moderately high. Sixteen studies including 3240 participants reported outcomes on depressive diagnosis. The risk of having a depressive disorder post-intervention was reduced immediately compared with no intervention (15 studies; 3115 participants risk difference (RD) -0.09; 95% confidence interval (CI) -0.14 to -0.05; P<0.0003), at three to nine months (14 studies; 1842 participants; RD -0.11; 95% CI -0.16 to -0.06) and at 12 months (10 studies; 1750 participants; RD -0.06; 95% CI -0.11 to -0.01). There was no evidence for continued efficacy at 24 months (eight studies; 2084 participant; RD -0.01; 95% CI -0.04 to 0.03) but limited evidence of efficacy at 36 months (two studies; 464 participants; RD -0.10; 95% CI -0.19 to -0.02). There was significant heterogeneity in all these findings. There was no evidence of efficacy in the few studies that compared intervention with placebo or attention controls.

AUTHORS' CONCLUSIONS

There is some evidence from this review that targeted and universal depression prevention programmes may prevent the onset of depressive disorders compared with no intervention. However, allocation concealment is unclear in most studies, and there is heterogeneity in the findings. The persistence of findings suggests that this is real and not a placebo effect. 

Hopelessness and positive and negative future thinking in parasuicide

OBJECTIVES

Hopelessness about the future is a key element in suicidal behaviour. The aim of the present study was to examine possible components of hopelessness, in particular, to contrast positive and negative future thinking and to examine separately number, expectancy, and value of anticipated positive and negative future experiences.

DESIGN

A correlational design.

METHOD

Repeat parasuicide patients (N = 441) were administered the Beck Hopelessness Scale, the Hospital Anxiety and Depression Scale and the future thinking task, a measure of future positive and negative thinking that assesses number, perceived likelihood, and perceived value of anticipated future positive and negative events.

RESULTS

Consistent with predictions, hopelessness correlated more strongly with lack of positive thoughts about the future than it did with presence of negative thoughts. Both positive and negative future thinking showed a relationship to hopelessness over and above their relationships to depression (positive future thinking) and anxiety (negative future thinking). Number and likelihood of positive events and likelihood and value of negative events showed both simple and partial relationships to hopelessness. Number of negative events related to hopelessness but only after the other future thinking variables had been controlled for and value of positive events no longer related to hopelessness after controlling for the other variables.

CONCLUSIONS

Hopelessness about the future in suicidal individuals is a multi-faceted construct but lack of positive future thinking is more important than presence of negative future thinking.

Psychological interventions for antisocial personality disorder

BACKGROUND

Antisocial personality disorder (AsPD) is associated with a wide range of disturbance including persistent rule-breaking, criminality, substance use, unemployment, homelessness and relationship difficulties.

OBJECTIVES

To evaluate the potential beneficial and adverse effects of psychological interventions for people with AsPD.

SEARCH STRATEGY

Our search included CENTRAL Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, PsycINFO, ASSIA, BIOSIS and COPAC.

SELECTION CRITERIA

Prospective, controlled trials in which participants with AsPD were randomly allocated to a psychological intervention and a control condition (either treatment as usual, waiting list or no treatment).

DATA COLLECTION AND ANALYSIS

Three authors independently selected studies. Two authors independently extracted data. We calculated mean differences, with odds ratios for dichotomous data.

MAIN RESULTS

Eleven studies involving 471 participants with AsPD met the inclusion criteria, although data were available from only five studies involving 276 participants with AsPD. Only two studies focused solely on an AsPD sample. Eleven different psychological interventions were examined. Only two studies reported on reconviction, and only one on aggression. Compared to the control condition, cognitive behaviour therapy (CBT) plus standard maintenance was superior for outpatients with cocaine dependence in one study, but CBT plus treatment as usual was not superior for male outpatients with recent verbal/physical violence in another. Contingency management plus standard maintenance was superior for drug misuse for outpatients with cocaine dependence in one study but not in another, possibly because of differences in the behavioural intervention. However, contingency management was superior in social functioning and counselling session attendance in the latter. A multi-component intervention utilising motivational interviewing principles, the 'Driving Whilst Intoxicated program', plus incarceration was superior to incarceration alone for imprisoned drink-driving offenders.

AUTHORS' CONCLUSIONS

Results suggest that there is insufficient trial evidence to justify using any psychological intervention for adults with AsPD. Disappointingly few of the included studies addressed the primary outcomes defined in this review (aggression, reconviction, global functioning, social functioning, adverse effects). Three interventions (contingency management with standard maintenance; CBT with standard maintenance; 'Driving Whilst Intoxicated program' with incarceration) appeared effective, compared to the control condition, in terms of improvement in at least one outcome in at least one study. Each of these interventions had been originally developed for people with substance misuse problems. Significant improvements were mainly confined to outcomes related to substance misuse. No study reported significant change in any specific antisocial behaviour. Further research is urgently needed for this prevalent and costly condition.

Pediatric emergency department suicidal patients: two-site evaluation of suicide ideators, single attempters, and repeat attempters

OBJECTIVE

Reducing youth suicide and suicide attempts are national priorities. Suicidal youth emergency department (ED) patients are at high risk for repeat and fatal attempts, yet information is lacking to guide service delivery. In one of the largest clinical studies of youth ED patients presenting with suicidality, we examine ideators, single attempters, and repeat attempters with the aim of clarifying optimal strategies for ED management and risk assessment.

METHOD

Consecutively admitted suicidal youths (10-18 years) from two EDs (N = 210) completed a questionnaire assessing sociodemographic, clinical, service use, and environmental stress variables.

RESULTS

Despite differences in background characteristics, high levels of depression, externalizing behavior, posttraumatic stress symptoms, substance use, and thought problems were observed across sites. Suicide attempt risk, defined along a continuum ranging from ideation to single attempts to repeat attempts, was predicted by higher levels of clinical symptoms, service use, and environmental stress. Specific stresses associated with increased suicide attempt risk were romantic breakups, exposure to suicide/suicide attempts, and pregnancy in self or partner. Significant predictors of attempt risk in the male-only subgroup were depression, thought problems, previous ED visits, and romantic breakups.

CONCLUSIONS

Pediatric ED patients presenting with suicidal ideation, single attempts, and repeat attempts fall along a continuum of increasing risk. Suicide attempt risk in males is associated with high levels of depression, but not with increased treatment rates, suggesting undertreatment in males, a group with particularly high risk for death by suicide. Treatment barriers must be addressed to achieve our national goal of reducing suicide/suicide attempts in youths.

Perspectives of mental health professionals and patients on self-injury in psychiatry: a literature review

Professionals in psychiatry often encounter patients who injure themselves. To explore the perspectives of mental health professionals and patients on self-injurious behavior and treatment, the authors carried out a literature review. The reviewers found little documented data that elucidated or discussed any shared understanding about self-injurious behavior between patients and professionals or between professionals themselves. Many of the problems experienced in relation to self-injury may be due to this lack of a common view. There were few evidence-based strategies for managing self-injury that received any attention in the literature. Future studies should focus on the development and testing of preventative interventions, putting particular emphasis on effective communication between professionals and patients.

Comparison of alternative methods of collection of service use data for the economic evaluation of health care interventions

Economic evaluation of health care interventions usually requires the collection of service use data to estimate the total cost of participants in an evaluation. There are a number of methods available to measure the quantity of services used but little is known about the relative accuracy of alternative methods. In a multicentre randomised controlled trial of interventions for the treatment of adults with recurrent episodes of deliberate self-harm (the POPMACT trial), health service data were collected by patient self-report after six and twelve months and also from GP records by independent investigators. Agreement for overall costs was relatively high. However, this hides substantial variation in agreement between the two sources of information for different services. The results suggest that GP records provide more accurate data on the use of general practice-based contacts than patient report, but less reliable information on contacts with other health services. Thus reliance on GP records for data on hospital services and other community health services based outside of general practice surgeries is not recommended. Future research should explore the level of agreement between patient report and other providing sector records, such as hospital records.

The bed requirement inventory: a simple measure to estimate the need for a psychiatric bed

OBJECTIVE

To develop an assessment of bed need that was as little affected by personal bias as possible.

METHOD

The Bed Requirement Inventory (BRI) is an eight-point scale designed to identify the appropriate use of an acute psychiatric bed. This is completed by a member of the ward staff, usually a nurse, and takes 5 minutes to fill in. The reliability, validity and feasibility of using the scale in normal practice were tested in a one-year study, and variations in inappropriate bed use described.

RESULTS

The inter-rater reliability of the scale was good (intra-class correlation coefficient = 0.63) and a comparison of the need for a psychiatric bed (comparing the BRI score with the judgement of an independent multidisciplinary group of professionals) also showed good agreement (k = 0.69), suggesting reasonable validity (although when the assessment was made by the named nurse agreement was less good). Results from a year-long survey in two West London hospitals showed that 17% of admissions were inappropriate and 32% had delayed discharge, black Caribbean patients had a significantly higher proportion (25%) of inappropriate admission than others (11%) and those referred from housing charities and hostels had a higher proportion (50%) of inappropriate bed use at some time than other groups (33%).

CONCLUSIONS

The Bed Requirement Inventory is a quick and reliable method of determining the appropriate use of a psychiatric bed and could be of use in estimating local bed needs. Delayed discharge remains a serious reason for inappropriate bed use in London.

The Social Functioning Questionnaire: A Rapid and Robust Measure of Perceived Functioning

BACKGROUND

The Social Functioning Questionnaire (SFQ), an eight-item selfreport scale (score range 0-24), was developed from the Social Functioning Schedule (SFS), a semi-structured interview which has been used primarily with non-psychotic patients and has good test-retest and inter-rater reliability as well as construct validity. The SFQ was developed following the need for a quick assessment of perceived social function.

AIMS

To give further details of old and new data sets from studies involving over 4000 subjects assessed with the SFQ illustrating its epidemiological and clinical associations.

METHOD

New data were analysed from a national epidemiological study, a comparison of key-worker and subject versions of the SFQ, and reanalysis of data from three earlier clinical studies, of psychiatric emergencies, general practice psychiatric patients and those with recurrent psychotic illnesses. These data were examined further to determine their range, their relationship to other clinical measures, and change over time in clinical trials.

RESULTS

The population mean score in 4164 subjects was 4.6 and the data from all studies suggested that a score of 10 or more indicated poor social functioning. Those presenting as psychiatric emergencies had the poorest social function (mean 11.4) and psychiatric patients from general practice the best function (mean 7.7) of the clinical populations. The eight item scores had a normal distribution in psychiatric populations and a skewed one in a normal population; scores were relatively stable over the short (weeks) and long-term (months), and were high in the presence of acute mental health disturbance and personality disorder, giving support to the validity of the scale. The results from a UK sample of a randomly selected population specifically weighted for ethnic minorities showed similar social function across groups.

Preventing suicidal behaviour in a general hospital psychiatric service: priorities for programming

PURPOSE

General hospital psychiatric services are able to provide leadership and coordinate the development of suicide prevention programs for individuals serviced in general hospital settings. We completed this literature review to suggest priorities for programming.

METHODS

Our procedure was to update the review by Gunnell and Frankel that guided priorities for Health of the Nation, the national suicide prevention strategy in the UK. We completed a search, using the terms suicide prevention and control, of all English-language research and clinical trials conducted between January 1, 1994, and May 1, 2004.

RESULTS

We identified 82 papers. Of these, 48 were excluded and the remaining 34 were grouped by secondary care setting categories. We found no articles on screening tools for predicting risk of suicide, 16 articles on interventions for individuals with suicidal behaviour, 14 articles on the treatment of major psychiatric disorders, 1 article and 1 published abstract on discharge from hospital, and 2 articles on reducing access to means.

CONCLUSIONS

Based on a review of each category, we make several program and policy recommendations, including regularly updating clinical assessment skills, using guidelines for assessment of patients following a suicide attempt, assessing the risk of suicide 24 to 48 hours before discharge from hospital, and incorporating education about reducing access to means into routine psychiatric care.

Prevalence of personality disorder in alcohol and drug services and associated comorbidity

AIMS

To compare the prevalence of personality disorder in alcohol and drug populations with special attention to its impact on psychopathology and service characteristics.

DESIGN

Cross-sectional survey.

SETTING

Three alcohol and four drug services in four urban UK centres.

PARTICIPANTS

Two hundred and sixteen drug and 64 alcohol service patients randomly sampled from current treatment populations.

MEASUREMENTS

A treatment population census recorded demographic and diagnostic data. Patient interviews assessed the presence, cluster type and severity of personality disorder using the Quick Personality Assessment Schedule (PAS-Q). Other psychopathology was measured using the Comprehensive Psychopathological Rating Scale (CPRS). A case-note audit recorded psychotic psychopathology using the OPCRIT schedule and data regarding social morbidity.

FINDINGS

The overall prevalence of personality disorder was 37% in the drug service sample and 53% in the alcohol service sample. The distribution of severity and clusters differed markedly between the two samples. There was a significant association between the severity of personality disorder and psychopathology in both samples. Levels of morbidity associated with clusters B and C were similar. Clinical diagnosis of personality disorder showed high specificity but low sensitivity when compared to PAS-Q.

CONCLUSIONS

In both alcohol and drug service populations, personality disorder is associated with significantly increased rates of psychopathology and social morbidity that worsens with increasing severity of the disorder. Despite this, personality disorder is poorly identified by clinical staff. The PAS-Q may be useful as a clinical assessment tool in the substance misuse population for the early identification and management of patients with personality disorder.

Personality disorder and future-directed thinking in parasuicide

Parasuicide patients have been found to lack positive expectations for the future. The aim of the present study was to look at variations in this lack of positive future-thinking as a function of personality status. A sample (N = 442) of repeat parasuicide patients was assessed on positive and negative future-thinking and the presence of personality disorder or personality difficulty. Those with a Cluster B personality disorder (borderline or dissocial) were significantly lower in positive future-thinking than those with no Cluster B symptoms or those with Cluster B personality difficulty. Neither Cluster A nor Cluster C symptomatology was related to positive future-thinking. Negative future-thinking was not significantly related to any type of personality disorder or difficulty. The results are interpreted as evidence of the importance of personality status in influencing positive future-thinking and gives some indications of why those with Cluster B personality disorder have such high rates of recurrent self-harm.

Differential effects of manual assisted cognitive behavior therapy in the treatment of recurrent deliberate self-harm and personality disturbance: the POPMACT study

A total of 480 patients were treated in a large, multicenter randomized trial of a brief form of cognitive therapy, manual-assisted cognitive behavior therapy (MACT) versus treatment as usual (TAU) for recurrent deliberate self-harm. Each patient was randomized after a self-harm episode assessed at an accident and emergency center and followed up over 1 year. The main hypothesis tested was that those allocated to MACT would have a lower proportion of self-harm episodes in the succeeding year. A total of 60% of those allocated to MACT had face-to-face treatment and 430 (90%) of all patients had self-harm data recorded after 1 year. Although the results showed no significant difference between those repeating self-harm in the MACT group (39%) compared with the TAU group (46%) (P = 0.20), the treatment was cost effective (10% cheaper than TAU) and the frequency of self-harm episodes was fewer (50%) in the MACT group. A total of nine of 10 patients had some personality disturbance (42% of these with disorder), and for those where information on parasuicide events was collected, the proportion having a repeat episode ranged from 33% to 63% for different personality disorders. Those with BPD were most likely to repeat episodes quickly (mean 89 days for 25% to repeat) with dissocial personality disorder (equivalent mean 384 days) the slowest to repeat. Total costs were significantly greater in those with personality disorder and were reduced in those allocated to MACT; this saving was reversed in those with borderline disorder. On average, MACT appeared to increase the cost of those patients with BPD (BPD) and reduce the cost of those with other personality disorders. It is concluded that MACT has value in preventing self-harm cost effectively but this appears to be confined mainly to those who do not have BPD.
