The predictive value of the dynamic risk outcome scales (DROS) for recidivism in (forensic) clients with mild intellectual disabilities or borderline intellectual functioning

BACKGROUND

The dynamic risk outcome scales (DROS) was developed to assess treatment progress of clients with mild intellectual disability or borderline intellectual functioning using dynamic risk factors. We studied the predictive value of the DROS on various classifications and severity levels of recidivism.

METHOD

Data of 250 forensic clients with intellectual disabilities were linked to recidivism data from the Judicial Information Service in the Netherlands. Receiver operating characteristics (ROC) analyses were used to determine the predictive values.

RESULTS

The DROS total score could not significantly predict recidivism. A DROS recidivism subscale predicted general, violent and other recidivism. These predictive values were comparable to those of a Dutch tool validated for risk assessment in the general forensic population.

CONCLUSIONS

The DROS recidivism subscale predicted various classifications of recidivism better than chance. At present, the DROS appears to have no added value beyond the HKT-30 for the purpose of risk assessment.

Transforensic psychiatry: Addressing inpatient aggression in the "gray zone" between general and forensic psychiatric care

A minority of psychiatric patients are unfit for general psychiatric care due to offensive behavior that renders them at risk of coming into contact with the criminal justice system. In the absence of criminal proceedings, these patients find themselves in the "gray zone" between general and forensic psychiatric care. To accommodate these patients, we established a "transforensic" ward. Instead of applying forensic treatment elements reactively (as part of a criminal sentence, after an offense has been committed), we applied it preventively (so as to avert offending behavior and resultant criminal sentences). Psychometric psychopathology and violence risk assessment scores were substantially lower at discharge than at admission (Cohen's ds = -0.3 to -0.6). These results offer ground for cautious optimism about the efficacy of transforensic care in serving as a safety net for psychiatric patients who are found to be unfit for general psychiatric care on account of their aggressive behavior.

Improvement in the quality of life of outpatients with severe mental illness in conjunction with intellectual disabilities and post-traumatic stress disorder

BACKGROUND

Elucidating the influence of mild intellectual disability (MID; IQ 50-70)/borderline intellectual functioning (BIF; IQ 70-85) and (comorbid) post-traumatic stress disorder (PTSD) on the quality of life of patients with serious mental illness (SMI) could improve their mental health care.

METHOD

This study comprises a prospective longitudinal cohort study using routine outcome monitoring data. The cohort comprised 601 patients who had undertaken at least one Manchester Short Assessment of Quality of Life (MANSA). The scores for screeners to detect MID/BIF and PTSD were analysed, and a repeated measures analysis of variance and a multi-level linear regression was performed on the MANSA scores.

RESULTS

The average quality of life for all patient groups increased significantly over time. A between-subject effect on quality of life was observed for PTSD, but not MID/BIF.

CONCLUSIONS

PTSD but not MID/BIF is associated with a lesser quality of life over time.

Effects of multivitamin, mineral and n-3 polyunsaturated fatty acid supplementation on aggression among long-stay psychiatric in-patients: randomised clinical trial

BACKGROUND

Aggression and violent incidents are a major concern in psychiatric in-patient care. Nutritional supplementation has been found to reduce aggressive incidents and rule violations in forensic populations and children with behavioural problems.

AIMS

To assess whether multivitamin, mineral and n-3 polyunsaturated fatty acid supplementation would reduce the number of aggressive incidents among long-stay psychiatric in-patients.

METHOD

The trial was a pragmatic, multicentre, randomised, double-blind placebo-controlled study. Data were collected from 25 July 2016 to 29 October 2019, at eight local sites for mental healthcare in The Netherlands and Belgium. Participants were randomised (1:1) to receive 6-month treatment with either three supplements containing multivitamins, minerals and n-3 polyunsaturated fatty acid, or placebo. The primary outcome was the number of aggressive incidents, determined by the Staff Observation Aggression Scale - Revised (SOAS-R). Secondary outcomes were patient quality of life, affective symptoms and adverse events.

RESULTS

In total, 176 participants were randomised (supplements, n = 87; placebo, n = 89). Participants were on average 49.3 years old (s.d. 14.5) and 64.2% were male. Most patients had a psychotic disorder (60.8%). The primary outcome of SOAS-R incidents was similar in supplement (1.03 incidents per month, 95% CI 0.74-1.37) and placebo groups (0.90 incidents per month, 95% CI 0.65-1.19), with a rate ratio of 1.08 (95% CI 0.67-1.74, P = 0.75). Differential effects were not found in sensitivity analyses on the SOAS-R or on secondary outcomes.

CONCLUSIONS

Six months of nutritional supplementation did not reduce aggressive incidents among long-stay psychiatric in-patients.

"Disruptive Behavior" or "Expected Benefit" Are Rationales of Seclusion Without Prior Aggression

OBJECTIVE

In the Netherlands, seclusion of patients with a psychiatric disorder is a last-resort measure to be used only in the event of (imminent) severe danger or harm. Although aggressive behavior is often involved, seclusions not preceded by aggression also seem to occur. We sought insight into the non-aggressive reasons underlying seclusion and investigated the factors associated with it.

METHOD

We included all patients admitted to a Dutch psychiatric hospital in 2008 and 2009. Seclusions had been registered on Argus-forms, and aggression incidents had been registered on the Staff Observation Aggression Scale-Revised (SOAS-R), inspectorate forms and/or patient files. Determinants of seclusion with vs. without prior aggression were analyzed using logistic regression. Reasons for seclusion without prior aggression were evaluated qualitatively and grouped into main themes.

RESULTS

Of 1,106 admitted patients, 184 (17%) were secluded at some time during admission. Twenty-one (11.4%) were excluded because information on their seclusion was lacking. In 23 cases (14%), neither SOAS-R, inspectorate forms nor individual patient files indicated any aggression. Univariable and multivariable regression both showed seclusion without preceding aggression to be negatively associated with daytime and the first day of hospitalization. In other words, seclusion related to aggression occurred more on the first day, and during daytime, while seclusion for non-aggressive reasons occurred relatively more after the first day, and during nighttime. Our qualitative findings showed two main themes of non-aggressive reasons for seclusion: "disruptive behavior" and "beneficial to patient."

CONCLUSION

Awareness of the different reasons for seclusion may improve interventions on reducing its use. Thorough examination of different sources showed that few seclusions had not been preceded by aggression. The use of seclusion would be considerably reduced through interventions that prevent aggression or handle aggression incidents in other ways than seclusion. However, attention should also be paid to the remaining reasons for seclusion, such as handling disruptive behavior and focusing on the beneficial effects of reduced stimuli. Future research on interventions to reduce the use of seclusion should not only aim to reduce seclusion but should also establish whether seclusions preceded by aggression decrease different from seclusions that are not preceded by aggression.

Heart Rate and Skin Conductance Associations with Physical Aggression, Psychopathy, Antisocial Personality Disorder and Conduct Disorder: An Updated Meta-Analysis

The associations between physiological measures (i.e., heart rate and skin conductance) of autonomic nervous system (ANS) activity and severe antisocial spectrum behavior (AB) were meta-analyzed. We used an exhaustive partitioning of variables relevant to the ANS-AB association and investigated four highly relevant questions (on declining effect sizes, psychopathy subscales, moderators, and ANS measures) that are thought to be transformative for future research on AB. We investigated a broad spectrum of physiological measures (e.g., heart rate (variability), pre-ejection period) in relation to AB. The search date for the current meta-analysis was on January 1^st, 2020, includes 101 studies and 769 effect sizes. Results indicate that effect sizes are heterogeneous and bidirectional. The careful partitioning of variables sheds light on the complex associations that were obscured in previous meta-analyses. Effects are largest for the most violent offenders and for psychopathy and are dependent on the experimental tasks used, parameters calculated, and analyses run. Understanding the specificity of physiological reactions may be expedient for differentiating between (and within) types of AB.

The associations of quality of life and general functioning with trauma, borderline intellectual functioning and mild intellectual disability in outpatients with serious mental illness

BACKGROUND

Trauma and intellectual disability are highly prevalent in the serious mental ill (SMI). Little is known of their impact on general functioning and quality of life.

AIM

This study investigated the association of trauma and intellectual disability (ID) with general functioning and quality of life in SMI.

METHODS

Patient characteristics and diagnoses were extracted from electronic patient records. We used the Trauma Screening Questionnaire (TSQ), the Screener for Intelligence and Learning Disabilities (SCIL), the Health of the Nation Outcome Scale (HoNOS) and the Manchester Short Assessment of Quality of Life (MANSA) to asses trauma, intellectual impairment, general functioning and quality of life. Proportions on cut-off scores were analysed with cross-tabulations, questionnaire scores with t-tests. Multivariable associations were determined by logistic regression analysis.

RESULTS

611 patients from an outpatient service were assessed. Trauma and ID were associated with each other (r = -0.207). Trauma was associated with worse general functioning and a lower quality of life. Mild intellectual disability (MID) or borderline intellectual functioning (BIF) were associated with worse general functioning.

CONCLUSIONS

For patients with SMI, trauma and ID should be identified early in care to treat the lower general functioning and quality of life it caused.

Increased prevalence of intellectual disabilities in higher-intensity mental healthcare settings

BACKGROUND

It has been suggested that people with intellectual disabilities have a higher likelihood to develop psychiatric disorders, and that their treatment prognosis is relatively poor.

AIMS

We aimed to establish the prevalence of intellectual disability in different mental healthcare settings, and estimate percentage of cognitive decline. We hypothesised that the prevalence of intellectual disabilities increases with intensity of care.

METHOD

A cross-sectional study was conducted in different settings in a mental healthcare trust in the Netherlands. We used the Screener for Intelligence and Learning Disabilities (SCIL) to identify suspected mild intellectual disability (MID) or borderline intellectual functioning (BIF). We identified patients with a high level of education and low SCIL score to estimate which patients may have had cognitive decline.

RESULTS

We included 1213 consecutive patients. Over all settings, 41.4% of participating patients were positive for MID/BIF and 20.2% were positive for MID only. Prevalence of suspected MID/BIF increased by setting, from 27.1% in out-patient settings to 41.9% in flexible assertive community treatment teams and admission wards, to 66.9% in long-stay wards. Only 85 (7.1%) of all patients were identified as possibly having cognitive decline. Of these, 25.9% were in long-stay wards and had a diagnosis of schizophrenia or substance use disorder.

CONCLUSIONS

Low intellectual functioning is common in Dutch mental healthcare settings. Only a modest number of patients were identified as suffering from cognitive decline rather than suspected MID/BIF from birth. Therefore, we recommend improved screening of psychiatric patients for intellectual functioning at the start of treatment.

Number of Seclusions in the Netherlands Higher in the 7 Years Since the End of a Nationwide Seclusion-Reduction Program

Introduction: Between 2006 and 2012 the Dutch government funded a nationwide program for reducing the use of seclusion. Although an initial first trend study showed that the reported number of seclusions declined during the program, the objective of a 10% annual decrease was not met. We wished to establish whether the decline had continued after funding ended in 2012. Method: Using quasi Poisson time series modeling, we retrospectively analyzed the nationally reported numbers of seclusion and involuntary medication between 1998 and 2019, i.e., before, during and after the end of the nationwide program, with and without correction for the number of involuntary admissions. Results: With and without correction for the number of involuntary admissions, there were more seclusions in the seven years after the nationwide program than during the nationwide program. Although the reported number of involuntary medications also increased, the rate of increase was slower after the end of the nationwide program than before. Conclusions: Rather than continuing to decrease after the end of the nationwide program, the number of seclusions rose. This may mean that interventions intended to reduce the use of seclusion within this program are not properly sustained in daily clinical care without an ongoing national program.

Diagnose, indicate, and treat severe mental illness (DITSMI) as appropriate care: A three-year follow-up study in long-term residential psychiatric patients on the effects of re-diagnosis on medication prescription, patient functioning, and hospital bed utilization

Background.

While polypharmacy is common in long-term residential psychiatric patients, prescription combinations may, from an evidence-based perspective, be irrational. Potentially, many psychiatric patients are treated on the basis of a poor diagnosis. We therefore evaluated the DITSMI model (i.e., Diagnose, Indicate, and Treat Severe Mental Illness), an intervention that involves diagnosis (or re-diagnosis) and appropriate treatment for severely mentally ill long-term residential psychiatric patients. Our main objective was to determine whether DITSMI affected changes over time regarding diagnoses, pharmacological treatment, psychosocial functioning, and bed utilization.

Methods.

DITSMI was implemented in a consecutive patient sample of 94 long-term residential psychiatric patients during a longitudinal cohort study without a control group. The cohort was followed for three calendar years. Data were extracted from electronic medical charts. As well as diagnoses, medication use and current mental status, we assessed psychosocial functioning using the Health of the Nations Outcome Scale (HoNOS). Bed utilization was assessed according to length of stay (LOS). Change was analyzed by comparing proportions of these data and testing them with chi-square calculations. We compared the numbers of diagnoses and medication changes, the proportions of HoNOS scores below cut-off, and the proportions of LOS before and after provision of the protocol.

Results.

Implementation of the DITSMI model was followed by different diagnoses in 49% of patients, different medication in 67%, some improvement in psychosocial functioning, and a 40% decrease in bed utilization.

Conclusions.

Our results suggest that DITSMI can be recommended as an appropriate care for all long-term residential psychiatric patients.

Psychometric Properties of the Externalizing Spectrum Inventory: Replication and Extension across Clinical and Non-Clinical Samples

The Externalizing Spectrum Inventory aims at assessing personality features that underlie externalizing disorders such as substance abuse and antisocial behaviors. The objective was to replicate the psychometric properties of the 160-item Externalizing Spectrum Inventory in Dutch clinical and non-clinical samples. First, Cronbach's alpha, test-retest reliability and the factor structure were analyzed on a mixed sample of inpatients (n = 149), undergraduates (n = 227), and community participants (n = 178). The factor structure was evaluated through confirmatory and exploratory factor analyses; for the latter Parallel Analysis was used, based on Minimum Rank Factor Analysis. Next, the criterion validity was analyzed using the Aggression Questionnaire and the NEO-Five Factor Inventory as external measures. The Dutch Externalizing Spectrum Inventory subscales showed sufficient reliability (α=.68-.94; ICC=.68-.91), except in the undergraduate sample (α=.49-.96; ICC=.43-.97). The factor structure of the Externalizing Spectrum Inventory was not confirmed and the exploratory analysis yielded different factor solutions across samples. The criterion validity was supported with regard to trait aggression and partly supported with regard to the Five Factor Model. The results suggest that the ESI-160 and its original factor model can be used for prediction purposes. However, further research of the factor structure is strongly recommended.

[The predictive value of the Dynamic Risk Outcome Scales (DROS) for predicting recidivism in (forensic) patients with mild intellectual disabilities or borderline intellectual functioning]

The Dynamic Risk Outcome Scales (DROS) was developed to assess treatment progress of patients with mild intellectual disability (MID) or borderline intellectual functioning (BIF) and severe behavioral and/or psychiatric problems. Because of the focus on dynamic risk factors, practitioners also see this instrument as a tool for risk assessment.<br/> AIM: To investigate the predictive value of the DROS on different classifications and severities of recidivism.<br/> METHOD: DROS data from the routine outcome monitoring (ROM) of 250 forensic patients with MID-BIF who were discharged between 2007 and end of 2014 were linked to recidivism data from the Judicial Information Service.<br/> RESULTS: The DROS total score predicted general, violence and sexual recidivism better than chance (AUCs > 0.58), although the effect was small. A DROS-recidivism subscale predicted general, violence and other recidivism with a medium to large effect (AUCs > 0.67). The predictive values of the DROS total score and DROS-recidivism subscale were comparable to those of the Historic, Clinical, Future (in Dutch: HKT)-30.<br/> CONCLUSION: The DROS total score and DROS-recidivism subscale predict different classifications of recidivism better than chance. However, for risk assessment the DROS appears to have no added value to the HKT-30.

[The predictive value of mild intellectual disability/ borderline intellectual functioning and ptsd for treatment results in severely mentally Ill patients]

Little is known about the influence of mild intellectual disability/borderline intellectual functioning (mid/biF) or posttraumatic stress disorder (ptsd) on treatment results in severely mentally ill (smi). <br/> AIM: To investigate whether screeners determining mid/biF or ptsd are associated with less favorable treatment outcome in smi.<br/> METHOD: The screener for intelligence and learning disabilities (scil) was used to screen for mid/biF. The trauma screening questionnaire (tsq) was used to detect ptsd. Outcomes of these screeners were associated with repeated measures on the health of the nation outcome scales (HoNOS) in 628 smi at the Mental Care Centre of Oost Brabant.<br/> RESULTS: In 628 patients one or more HoNOS was acquired. In 352 (56%) patients a scil was acquired, in 334 (53%) patients a tsq. The largest improvement was observed in patients not meeting the criteria for mid/biF and/or ptsd. Less improvement was observed in patients with ptsd and a suspected iq between 70-85, estimated with the scil. No significant change on the HoNOS was observed in patients with an estimated iq below 70.<br/> CONCLUSION: Routine screening for mid/biF and ptsd symptoms is important for early recognition of the disorder, resulting in providing better treatment interventions for patients with mid/biF and ptsd.

[Suicide in individuals with mild intellectual disabilities]

Little is known about suicide among individuals with mild intellectual disabilities (mid).<br/> AIM: To explore risk factors for suicide among a small group of clients with mid who committed suicide.<br/> METHOD: Case files of 11 clients with mid were analysed using the Integrated Motivational Volitional model.<br/> RESULTS: Most suicides seem to have taken place impulsively and not on the basis of a predetermined plan. Most clients had comorbid mental health problems, predominantly trauma-related, impulse control and externalizing behavioural problems. The (imminent) loss of contact, such as in the case of transfer from one ward to another ward or to a facility, seems an important risk factor for suicide. <br/> CONCLUSION: Clients with mid residing in a treatment facility may have an increased risk of suicide because of an interaction between client characteristics and treatment context.

Validation of the Dutch Version of the Brief Negative Symptom Scale

PURPOSE

The Brief Negative Symptom Scale (BNSS) was developed to measure negative symptoms of schizophrenia. However, the Dutch translation of this instrument, called the "Korte Schaal voor Negatieve Symptomen" (KSNS), has not yet been validated. This study investigates the validity and reliability of this Dutch version of the instrument.

PATIENTS AND METHODS

The Psychotic Symptom Rating Scale (PSYRATS), Calgary Depression Scale for Schizophrenia (CDSS), the Health of the Nation Scale (HoNOS) and the KSNS were used for routine outcome monitoring to measure symptoms in 28 patients with a psychotic disorder who were being treated on a long-stay ward.

RESULTS

The internal consistency of the KSNS is fair to good. The inter-rater reliability is excellent. The concurrent validity is moderate but acceptable. The correlations between the KSNS and scales for depression and positive symptoms were not significant, which indicate good divergent validity.

CONCLUSION

Despite the small sample size of the current study, we conclude that the BNSS, called the KSNS in Dutch, appears to be a reliable and valid tool for investigating negative symptoms in detail in patients with psychotic disorders.

Attributional styles of support staff working with people with intellectual disabilities exhibiting challenging behaviour

Background

Attributions are cognitive variables that influence a person's behaviour. Although a large volume of research has been conducted on the attributions of support staff with regard to challenging behaviour (CB) exhibited by people with intellectual disabilities (ID), studies on patterns of attributional dimensions (i.e. attributional styles) are scarce.

Method

Using semi‐structured interviews, 19 support staff members were asked to describe incidents of aggressive, self‐injurious and sexualized challenging behaviour. Data on attributions were analysed using the Leeds Attributional Coding System.

Results

Four attributional styles differed significantly for aggressive, self‐injurious and sexualized challenging behaviour. In addition, support staff members largely attributed these three types of CB to characteristics and behaviour of clients with ID.

Conclusions

The results indicate that it is important to train support staff to recognize and understand the ways in which their attributions and behaviour influence the existence and maintenance of CB.

Screening for intellectual disabilities and borderline intelligence in Dutch outpatients with severe mental illness

BACKGROUND

The reliability and validity of the Screener for Intelligence and Learning Disabilities (SCIL) are unknown in a population of outpatients with severe mental illness. The prevalence of mild or borderline intellectual disabilities (MBID); an umbrella term for people with borderline intellectual functioning (BIF) and mild intellectual disability (MID) in this population is also unknown.

METHODS

A total of 625 patients were screened with the SCIL, 201 of which also had IQ test results.

RESULTS

Cronbach's alpha of the SCIL was 0.73. The AUC value for detecting MBID was 0.81, and also 0.81 for detecting MID, with percentages of correctly classified subjects (when using the advised cut-off scores) being 73% and 79%, respectively. The SCIL results suggested that 40% of the patients were suspected of MBID and 20% of MID.

CONCLUSION

The SCIL seems to be an appropriate screening tool for MBID. It is important to screen for MBID because a substantial proportion of outpatients with severe mental illness appear to be functioning at this level. It is necessary to adapt treatment for these patients.

Self-Injurious Behavior in People with Intellectual Disabilities and Co-Occurring Psychopathology using the Self-Harm Scale: A Pilot Study

Self-injurious behavior (SIB) is one of the most detrimental behaviors for the person showing it, as well as for their environment. Nevertheless, structured clinical assessments of SIB are scarce. Staff completed a Self-Harm Scale (SHS) every time they witnessed SIB in clients with an intellectual disability (ID) and co-occurring psychopathology (N = 33). Descriptive statistics were conducted to explore the nature of the incidents of SIB and the characteristics of the people involved in the incidents. In 41 weeks, 104 SIB incidents were reported for 8 out of 33 clients (24%). Incidents were most prevalent on Mondays (23%). As far as the methods of SIB concerned, cutting was the most used method (63%). Clients who showed SIB differed significantly from clients who did not on gender, having a personality disorder and communicative abilities. This study was one of the few that used an incident-based record form to report SIB by direct observation. It is hoped that the SHS helps to gain more information about SIB, to improve individualized interventions. Further research is necessary to determine the psychometric properties and clinical utility of the scale.

On the Link Between Emotionally Driven Impulsivity and Aggression: Evidence From a Validation Study on the Dutch UPPS-P

The UPPS-P seems to be a promising instrument for measuring different domains of impulsivity in forensic psychiatric patients. Validation studies of the instrument however, have been conducted only in student groups. In this validation study, three groups completed the Dutch UPPS-P: healthy student ( N = 94) and community ( N = 134) samples and a forensic psychiatric sample ( N = 73). The five-factor structure reported previously could only be substantiated in a confirmatory factor analysis over the combined groups but not in the subsamples. Subgroup sample sizes might be too small to allow such complex analyses. Internal consistency, as assessed by Cronbach's alpha, was high on most subscale and sample combinations. In explaining aggression, especially the initial subscale negative urgency (NU) was related to elevated scores on self-reported aggression in the healthy samples (student and community). The current study is the second study that found a relationship between self-reported NU and aggression highlighting the importance of addressing this behavioural domain in aggression management therapy.

Seclusion Reduction in Dutch Mental Health Care: Did Hospitals Meet Goals?

OBJECTIVE

In 2006, a goal of reducing seclusion in Dutch hospitals by at least 10% each year was set. More than 100 reduction projects in 55 hospitals have been conducted, with €35 million in funding. This study evaluated the results.

METHODS

Data (2008 to 2013) were from a national register. Multilevel logistic regression examined determinants of seclusion.

RESULTS

Hospital participation in the register ranged from eight in 2008 to 66 in 2013, and admissions ranged from 11,300 to 113,290. The average yearly nationwide reduction of secluded patients was about 9%. Reduction was achieved in half of the hospitals. Some hospitals saw increased rates. In some hospitals where seclusion decreased, use of forced medication increased. Higher seclusion rates were associated with psychotic and bipolar disorders, male gender, and several ward types.

CONCLUSIONS

Seclusion decreased significantly, and forced medication increased. Rates varied widely between hospitals. For many hospitals, more efforts to reduce seclusion are needed.

Predicting inpatient aggression by self-reported impulsivity in forensic psychiatric patients

BACKGROUND

Empirical knowledge of 'predictors' of physical inpatient aggression may provide staff with tools to prevent aggression or minimise its consequences.

AIM

To test the value of a self-reported measure of impulsivity for predicting inpatient aggression.

METHODS

Self-report measures of different domains of impulsivity were obtained using the Urgency, Premeditation, Perseverance, Sensation seeking, Positive urgency (UPPS-P) impulsive behaviour scale with all 74 forensic psychiatric inpatients in one low-security forensic hospital. Aggressive incidents were measured using the Social Dysfunction and Aggression Scale (SDAS). The relationship between UPPS-P subscales and the number of weeks in which violent behaviour was observed was investigated by Poisson regression.

RESULTS

The impulsivity domain labelled 'negative urgency' (NU), in combination with having a personality disorder, predicted the number of weeks in which physical aggression was observed by psychiatric nurses. NU also predicted physical aggression within the first 12 weeks of admission.

CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

The results indicate that NU, which represents a patient's inability to cope with rejection, disappointments or other undesired feelings, is associated with a higher likelihood of becoming violent while an inpatient. This specific coping deficit should perhaps be targeted more intensively in therapy. Self-reported NU may also serve as a useful adjunct to other risk assessment tools and as an indicator of change in violence risk. Copyright © 2015 John Wiley & Sons, Ltd.

Adverse events and the relation with quality of life in adults with intellectual disability and challenging behaviour using psychotropic drugs

BACKGROUND

Psychotropic drugs are prescribed to approximately 30-40% of adults with intellectual disability (ID) and challenging behaviour, despite the limited evidence of effectiveness and the potential of adverse events.

AIMS

To assess the prevalence of adverse events in association with psychotropic drug use in adults with ID and challenging behaviour and to examine the relation of these adverse events with the person's quality of life.

METHOD

The presence of adverse events was measured with a questionnaire that had to be filled in by the physicians of the participants. Movement disorders were measured separately with a standardised protocol. The strength of the association between adverse events and Intellectual Disability Quality of Life-16 (IDQOL-16), and daily functioning was investigated using linear regression analyses, taking into account the severity of disease (CGI-S) as potential confounder.

RESULTS

Virtually all of 103 adults with ID and challenging behaviour had at least one adverse event (84.4%) and almost half had ≥3 adverse events (45.6%) across different subclasses. Using psychotropic drugs increased the prevalence of adverse events significantly. Respectively 13% of the patients without psychotropic drugs and 61% of the patients with ≥2 psychotropic drugs had ≥3 adverse events. Having adverse events had a significantly negative influence on the quality of life.

CONCLUSIONS

A large majority of all patients had at least one adverse event associated with psychotropic drug use. More attention is needed for these adverse events and their negative influence on the quality of life of these patients, taking into account the lack of evidence of effectiveness of psychotropic drugs for challenging behaviour.

[The validity of acute assessments of psychiatric conditions made by psychiatric emergency staff]

Earlier research carried out by the outreach psychiatric emergency team in the region of Uden / Veghel in the Netherlands indicated that the preliminary diagnosis of patients in crisis was associated with aggressive behaviour during the later contact between the patient and the staff of the psychiatric emergency team. An accurate diagnosis by the staff of the psychiatric emergency team is important because it should guide the patient towards the right type of treatment by the most appropriate team. The staff of the psychiatric emergency service who make the initial diagnosis are pressed for time and have only limited information.<br/> AIM: To find out what differences there are between the crisis team's initial diagnosis of the psychiatric condition of the patient in crisis and the later diagnosis made after more extensive psychiatric tests are carried out following the regular intake procedure.<br/> METHOD: Our study was based om 129 patients who, in the period of 2009 and 2010, were not known to mental health service and had not had any previous contact with the psychiatric emergency service. The first assessment of a patient's psychiatric condition made by a member of the psychiatric emergency service was compared with the later diagnosis made by a professional psychiatrist after the regular intake procedure. We then investigated the degree of agreement between the two diagnoses using Cohen's kappa so that we could test the validity of the initial screening of the patient's condition.<br/> RESULTS: We found that the staff of the psychiatric emergency team was able to achieve a result that was better than could be expected on the basis of chance. The Cohen's kappas varied between 0.81 for psychotic disorders to 0.31 for borderline personality disorders. Borderline personality disorders, however, tended to be overestimated by the psychiatric emergency staff.<br/> CONCLUSION: Although there was only limited agreement regarding various conditions, it is encouraging that the psychiatric emergency staff were able to assess psychotic disorders accurately on the basis of the initial information they had received. This result is important because in other studies psychotic symptoms were found to be associated with a higher likelihood of aggression during the later outreach consultation.

[Associations of short-term evaluation assessments and patient characteristics with the use of coercive measures]

BACKGROUND

Dutch mental health care institutes are currently making a tremendous effort to reduce the number of coercive measures they impose, such as seclusion. Despite this effort, a group of patients are still being subjected to enforced medication or seclusion.

AIM

To obtain more knowledge about which patient characteristics are associated with coercive measures and thereby to identify signs that could be acted upon at an earlier stage to prevent deterioration of the patient's condition and reduce the need for coercive measures.

METHOD

We performed a prospective, naturalistic three-month study involving patients in two acute psychiatric admission wards. To collect the data we required, we used two short-term risk-assessment instruments: the Brøset Violence Checklist (BVC) and the Kennedy Axis V (KA-V). By means of statistical analyses we investigated which patient characteristics were associated with the use of coercive measures.

RESULTS

Of the 179 patients, 52 patients (29%) were subjected to a coercive measure during the admission procedure. The following patient characteristics were found to be associated with coercive measures: a bipolar disorder, involuntarily admission, display of physical violence just before admission, scores on the BVC and the KA-V items assessing 'social skills' and 'violence'. The two BVC items 'attacks on objects' and 'display of physical violence just before admission' were the ones most strongly associated with seclusion.

CONCLUSION

Although the sensitivity of the regression model was modest, the associated patient characteristics, combined with the two short-term risk assessment scores, may be helpful for identifying at an early stage those patients who run a high risk of being subjected to coercive measures.

Structured Medication Review to Improve Pharmacotherapy in People with Intellectual Disability and Behavioural Problems

BACKGROUND

Polypharmacy and chronic drug use are common in people with intellectual disability and behavioural problems, although evidence of effectiveness and safety in this population is lacking. This study examined the effects of a structured medication review and aimed to improve pharmacotherapy in inpatients with intellectual disability.

METHODS

In a treatment facility for people with mild to borderline intellectual disability and severe behavioural problems, a structured medication review was performed. Prevalence and type of drug-related problems (DRPs) and of the recommended and executed actions were calculated.

RESULTS

In a total of 55 patients with intellectual disability and behavioural problems, 284 medications were prescribed, in which a DRP was seen in 106 (34%). No indication/unclear indication was the most prevalent DRP (70). Almost 60% of the recommended actions were also executed.

CONCLUSIONS

This high prevalence of DRPs is worrying. The structured medication review is a valuable instrument to optimize pharmacotherapy and to support psychiatrists in adequate prescribing of both psychotropic and somatic drugs.

Neurobiological changes after intervention in individuals with anti-social behaviour: a literature review

BACKGROUND

A neurobiological perspective has become accepted as a valuable approach for understanding anti-social behaviour. There is literature to suggest that, in non-offending populations, psychological treatments affect both neurobiological measures and clinical presentation. A theoretical position to this effect has been adopted with respect to offender treatment, but there has been no systematic review of empirical literature on this point.

AIMS

This study aimed to ascertain from published literature firstly whether there is evidence of change in neuropsychological or physiological measures after behavioural treatments/programmes for people with anti-social behaviour and secondly whether these neurobiological changes are associated with behavioural change.

METHOD

A systematic search strategy was formulated to include studies considering 'neurobiological factors', 'anti-social population', 'treatment' and 'treatment outcome'. The Maryland Scientific Methods Scale was used to select relevant studies of sufficient methodological quality.

RESULTS

Eleven studies were found, only one with adults. Overall, the values of specific neurobiological risk factors, particularly of basal cortisol, become less abnormal following intervention. There was some evidence for a link between change in neurobiological functioning and behavioural improvement.

CONCLUSIONS

Findings, although provisional, may provide new insights into the underlying mechanisms of interventions for anti-social behaviour. Future studies that include pre-treatment neurobiological assessment could help reveal physical vulnerabilities that interventions should target to improve treatment efficacy, and provide for objective, independent corroboration of change.

Changes in dynamic risk and protective factors for violence during inpatient forensic psychiatric treatment: predicting reductions in postdischarge community recidivism

Empirical studies have rarely investigated the association between improvements on dynamic risk and protective factors for violence during forensic psychiatric treatment and reduced recidivism after discharge. The present study aimed to evaluate the effects of treatment progress in risk and protective factors on violent recidivism. For a sample of 108 discharged forensic psychiatric patients pre- and posttreatment assessments of risk (HCR-20) and protective factors (SAPROF) were compared. Changes were related to violent recidivism at different follow-up times after discharge. Improvements on risk and protective factors during treatment showed good predictive validity for abstention from violence for short- (1 year) as well as long-term (11 years) follow-up. This study demonstrates the sensitivity of the HCR-20 and the SAPROF to change and shows improvements on dynamic risk and protective factors are associated with lower violent recidivism long after treatment.

Neurobiological factors as predictors of cognitive-behavioral therapy outcome in individuals with antisocial behavior: a review of the literature

This review focuses on the predictive value of neurobiological factors in relation to cognitive-behavioral therapy outcome among individuals with antisocial behavior. Ten relevant studies were found. Although the literature on this topic is scarce and diverse, it appears that specific neurobiological characteristics, such as physiological arousal levels, can predict treatment outcome. The predictive value of neurobiological factors is important as it could give more insight into the causes of variability in treatment outcome among individuals with antisocial behavior. Furthermore, results can contribute to improvement in current treatment selection procedures and to the development of alternative treatment options.

[Estimating and reporting aggression in relation to personal characteristics of emergency service workers]

BACKGROUND

Research on aggression in mental health care has focused mainly on patient characteristics, whereas very little research has been done on the characteristics of the care providers in their reporting of aggression.

AIM

To study the characteristics of the care providers of an emergency service in relation to the reporting of aggression.

METHOD

All emergency service workers( n = 21) in the Uden-Veghel region were asked to complete a neo-pi-r form. Before 576 outreach contacts had been made with patients in psychiatric crises, the Checklist of Risks in the Crisis-team (crc) was also completed and in cases where the patient exhibited aggressive behaviour, a soas-r form was filled in, following contact with the patient.

RESULTS

Significant differences were found between the psychiatric emergency service workers with regard to the mean estimates of the likelihood that they would experience aggression during the consultation and with regard to the proportion of patient contacts for which emergency workers reported aggression. There were indications that the level of conscientiousness of the emergency service workers was positively associated with a higher chance that they would report aggressive behaviour following the consultation. Furthermore, altruism was found to be negatively associated with the likelihood, as predicted by the service workers, that they would be confronted with aggression during contact with the patient.

CONCLUSION

Possibly, workers who scored high on conscientiousness and who work thoroughly and in a orderly and systematic manner and who keep to the rules are less flexible in their response to the patient during the interaction. As a result, the patient became irritated more quickly. On the other hand, it could be that conscientious workers completed the form-filling more carefully when aggression had to be reported and as a result they made higher preliminary estimates of the likelihood of aggression and a reported a larger number of incidents of actual aggression.

Prevalence and characteristics of psychotropic drug use in institutionalized children and adolescents with mild intellectual disability

Psychotropic drugs are a cornerstone in the treatment of psychopathology and/or behavioral problems in children with intellectual disability (ID), despite concerns about efficacy and safety. Studies on the prevalence of psychotropic drug use have mainly been focused on adults with ID or children without ID. Therefore the aim of this cross sectional study was to assess the prevalence and characteristics of psychotropic drug use in children with mild ID who were institutionalized in specialized inpatient treatment facilities in The Netherlands. Demographic data, psychiatric diagnoses, the nature of the behavioral problems, level of intellectual functioning, and medication data were extracted from medical records using a standardized data collection form. Adjusted relative risks (ARR) for the association between patient characteristics and psychotropic drug use were estimated with Cox regression analysis. Of the 472 included children, 29.4% (n=139) used any psychotropic drug, of which 15.3% (n=72) used antipsychotics (mainly risperidone), and 14.8% (n=70) used psychostimulants (mainly methylphenidate). Age, sex, and behavioral problems were associated with psychotropic drug use. Boys had a 1.7 (95%CI 1.1-2.4) higher probability of using psychotropic drugs, compared to girls adjusted for age and behavioral problems. Having any behavioral problem was associated with psychotropic drug use with an ARR of 2.1 (95%CI 1.3-3.3), adjusted for sex and age. The high prevalence of psychotropic drug use in children with ID is worrisome because of the lack of evidence of effectiveness (especially for behavioral problems) at this young age, and the potential of adverse drug reactions.

Differences in seclusion rates between admission wards: does patient compilation explain?

Comparison of seclusion figures between wards in Dutch psychiatric hospitals showed substantial differences in number and duration of seclusions. In the opinion of nurses and ward managers, these differences may predominantly be explained by differences in patient characteristics, as these are expected to have a large impact on these seclusion rates. Nurses assume more admissions of severely ill patients are related to higher seclusion rates. In order to test this hypothesis, we investigated differences in patient and background characteristics of 718 secluded patients over 5,097 admissions on 29 different admission wards over seven Dutch psychiatric hospitals. We performed an extreme group analysis to explore the relationship between patient and ward characteristics and the wards' number of seclusion hours per 1,000 admission hours. In a multivariate and a multilevel analysis, various characteristics turned out to be related to the number of seclusion hours per 1,000 admission hours as well as to the likelihood of a patient being secluded, confirming the nurses assumptions. The extreme group analysis showed that seclusion rates depended on both patient and ward characteristics. A multivariate and multilevel analyses revealed that differences in seclusion hours between wards could partially be explained by ward size next to patient characteristics. However, the largest deal of the difference between wards in seclusion rates could not be explained by characteristics measured in this study. We concluded ward policy and adequate staffing may, in particular on smaller wards, be key issues in reduction of seclusion.

[Assessing aggressive behaviour at the psychiatric emergency service with a checklist: a replication study]

BACKGROUND

In an earlier study it was found that aggressive behaviour by patients treated by the psychiatric emergency service could be predicted by the use of a newly developed instrument, the Checklist of Risks/ Crisis team (CRC). In this earlier study it was suggested that a replication study, with a larger database, was definitely needed in order to check these findings.

AIM

To find out in what circumstances patients (aggressive or non-aggressive) make contact with the crisis team and to ascertain the predictive validity of the CRC.

METHODS

During a period of four years (from 1 January 2006 to 31 December 2009) staff members completed the CRC before paying outreach visits to patients experiencing psychiatric crises in the community. In addition, if patients showed any aggressive behaviour during the visit, this was documented by means of the Staff Observation Aggression Scale-Revised (SOAS-r).

RESULTS

Our study replicated the earlier finding that the structured clinical risk assessment made on a visual analogue scale (VAS) of the CRC, together with the additional item about whether there were any potentially dangerous persons in the vicinity of the patient, seem to be useful "predictors" of aggression in the future (with correct classification in respectively 91 and 92%).

CONCLUSION

The class CRC, detailed monitoring of aggressive incidents by means of the SOAS-r, and the weekly discussions about these incidents all seem to be good instruments for analysing incidents and for increasing the safety of staff members. The methods and techniques introduced at the beginning of the project have gone hand in hand with the reduction in the number of aggressive acts directed at members of the psychiatric emergency service.

Determinants of seclusion after aggression in psychiatric inpatients

Some aggressive incidents in psychiatric wards result in seclusion, whereas others do not. We used the Staff Observation Aggression Scale-Revised and the mental health trust's database to identify determinants that predicted seclusion after aggression. These consisted of demographic, diagnostic, contextual, and aggression characteristics and were analyzed in a multilevel logistic regression. This showed associations between seclusion and aggression for the following: younger age, involuntary status, history of previous aggression, physical or dangerous violence, aggression being directed against objects, and a more severe incident. Thus, seclusion after aggression appears to be mainly predicted by aggression itself.

Aggression and seclusion on acute psychiatric wards: effect of short-term risk assessment

BACKGROUND

Short-term structured risk assessment is presumed to reduce incidents of aggression and seclusion on acute psychiatric wards. Controlled studies of this approach are scarce.

AIMS

To evaluate the effect of risk assessment on the number of aggression incidents and time in seclusion for patients admitted to acute psychiatric wards.

METHOD

A cluster randomised controlled trial was conducted in four wards over a 40-week period (n = 597 patients). Structured risk assessment scales were used on two experimental wards, and the numbers of incidents of aggression and seclusion were compared with two control wards where assessment was based purely on clinical judgement.

RESULTS

The numbers of aggressive incidents (relative risk reduction -68%, P<0.001) and of patients engaging in aggression (relative risk reduction RRR = -50%, P<0.05) and the time spent in seclusion (RRR = -45%, P<0.05) were significantly lower in the experimental wards than in the control wards. Neither the number of seclusions nor the number of patients exposed to seclusion decreased.

CONCLUSIONS

Routine application of structured risk assessment measures might help reduce incidents of aggression and use of restraint and seclusion in psychiatric wards.

Methodological issues in monitoring the use of coercive measures

PURPOSE

In many European countries, initiatives have emerged to reduce the use of seclusion and restraint in psychiatric institutions. To study the effects of these initiatives at a national and international level, consensus on definitions of coercive measures, assessment methods and calculation procedures of these coercive measures are required. The aim of this article is to identify problems in defining and recording coercive measures. The study contributes to the development of consistent comparable measurements definitions and provides recommendations for meaningful data-analyses illustrating the relevance of the proposed framework.

METHODS

Relevant literature was reviewed to identify various definitions and calculation modalities used to measure coercive measures in psychiatric inpatient care. Figures on the coercive measures and epidemiological ratios were calculated in a standardized way. To illustrate how research in clinical practice on coercive measures can be conducted, data from a large multicenter study on seclusion patterns in the Netherlands were used.

RESULTS

Twelve Dutch mental health institutes serving a population of 6.57 million inhabitants provided their comprehensive coercion measure data sets. In total 37 hospitals and 227 wards containing 6812 beds were included in the study. Overall seclusion and restraint data in a sample of 31,594 admissions in 20,934 patients were analyzed. Considerable variation in ward and patient characteristics was identified in this study. The chance to be exposed to seclusion per capita inhabitants of the institute's catchment areas varied between 0.31 and 1.6 per 100.000. Between mental health institutions, the duration in seclusion hours per 1000 inpatient hours varied from less than 1 up to 18h. The number of seclusion incidents per 1000 admissions varied between 79 up to 745. The mean duration of seclusion incidents of nearly 184h may be seen as high in an international perspective.

CONCLUSION

Coercive measures can be reliably assessed in a standardized and comparable way under the condition of using clear joint definitions. Methodological consensus between researchers and mental health professionals on these definitions is necessary to allow comparisons of seclusion and restraint rates. The study contributes to the development of international standards on gathering coercion related data and the consistent calculation of relevant outcome parameters.

Representation of people with intellectual disabilities in randomised controlled trials on antipsychotic treatment for behavioural problems

BACKGROUND

Behavioural problems are common in people with intellectual disability (ID) and are often treated with antipsychotics.

AIM

To establish the frequency and characteristics of people with ID included in randomised controlled trials (RCTs) on antipsychotic treatment for behavioural problems, and to investigate the quality of these RCTs.

METHODS

A literature search in EMBASE, PubMed and Cochrane was performed and reviewed.

RESULTS

People with ID participated in 27 of the 100 included RCTs. The RCTs were of good quality but smaller compared with trials in patients with dementia or schizophrenia (average sample sizes = 55, 124 and 374). In 13/27 trials no clear definition of ID was given. Over 25 different outcome measures were used to assess behavioural problems.

CONCLUSIONS

Studies in which people with ID are included are of a sufficient quality, but of a small size. The heterogeneity in the characteristics of the ID population included as well as in the applied assessment instruments makes performing meta-analyses unfeasible.

[Personality traits of staff members of the psychiatric emergency services]

BACKGROUND

In the course of their duties staff members of the psychiatric emergency services may quite often find themselves in unpredictable and, in some cases, threatening situations. For this reason, staff working for the emergency services need to have specific personality traits.

AIM

To investigate whether staff members of the emergency services differ from well-educated members of the general public as far as personality traits are concerned.

METHOD

The staff of the mental health teams of Oost Brabant in the Netherlands (Uden/ Veghel and Helmond regions) were asked to complete an NEO-PI-R designed to assess their main personality traits. Of the 59 staff members who were invited to participate, 44 completed and returned the questionnaire (76%). The scores of the 44 staff members were compared to those of a norm group of persons with a similar educational level in the general population.

RESULTS

The staff of the crisis teams were found to have significantly lower scores on the personality dimension 'Neurotism' and particularly on the facets 'Vulnerability' and 'Self-consciousness' of this dimension. The psychiatric crisis staff had higher scores on the facets 'Competence' and 'Self-discipline' and lower scores on the 'Candour/Frankness/Openness'. Compared to the social workers, the psychiatrists scored higher on the facets 'Assertiveness' and 'Openness to ideas'.

CONCLUSION

The lower scores found on the main personality dimension 'Neuroticism' and particularly on the facet 'Vulnerability' suggest that members of the psychiatric crisis team remain calm in stressful situations and are emotionally rather stable persons. Such personality traits can be important in threatening situations where peace and calm have to be preserved. However, in view of the limited sample size and the relatively large number of statistical tests, the findings of this exploratory study should be interpreted with caution.

Trials assessing parmacotherapeutic management of aggression in psychiatric patients: comparability with clinical practice

INTRODUCTION

In a previous review of randomized controlled trials (RCTs) on the pharmacotherapeutic management of aggression, it was shown that there is only weak evidence of effectiveness. In the present study we aim to determine comparability of patients included in these RCTs and patients of psychiatric long-stay wards.

METHODS

Exclusion criteria that were used in at least 20% of the RCTs were applied to a sample of aggressive inpatients from clinical practice, in order to find what proportion of these patients would be eligible to participate in the reviewed, high quality RCTs.

RESULTS

Only 30% of aggressive psychiatric patients as seen in clinical practice would be eligible to participate in a typical randomized controlled trial based on the most frequently applied exclusion criteria.

DISCUSSION

The low comparability of patients included in RCTs with those seen in clinical practice may decrease the generalizability of the findings form RCTs to clinical practice.

[Assessing aggression in patients of the mental health crisis service]

BACKGROUND

Care workers of the outreach psychiatric crisis team are frequently confronted with aggressive patients. To prevent dangerous situations from developing it could be advantageous to have in place a method of risk assessment that is based on information about patients before they are actually contacted by the crisis team.

AIM

To test the predictive validity of an instrument specifically designed to assess the risks of aggression from severely disturbed psychiatric patients before they are seen by the crisis team.

METHODS

Over a period of two years and prior to any outreach contact with patients in crisis situations a Checklist of Risks to the Crisis team (CRC) was completed. Then, following outreach contact with the patient any perceived aggression was recorded by means of the Staff Observation Aggression Scale-Revised (SOAS-R).

RESULTS

Aggressive behaviour by patients was observed during 51 of 499 crisis contacts with members of the outreach crisis team. On the basis of three factors in the CRC, namely the clinical assessment on a visual-analogue scale, an estimate of the number of aggressive persons in the vicinity of the crisis patient concerned and the reporting of crises by the patient himself, it was possible to predict outwardly directed aggression with a sensitivity of 74% and a specificity of 84%.

CONCLUSIONS

Although the findings still need to be reproduced, an instrument such as the crc could be very useful to members of the crisis service.

[Behavioural changes during forensic psychiatric treatment: a multicenter study]

BACKGROUND

In forensic psychiatry it is essential that patients' risks of reoffending are assessed as reliably as possible. The risk assessment instrument hkt-30 assesses both static and dynamic risk factors. It is assumed that dynamic risk factors should change when a patient receives treatment.

AIM

To find out whether dynamic risk factors changed during the course of forensic psychiatric treatment.

METHOD

The hkt-30 was administered 984 times for forensic psychiatric patients in 3 different forensic psychiatric centres, in the period June 2003-November 2006. For 513 patients the instrument was administered at least once, for 313 this was done at least twice and for 158 patients for three years in succession. By subdividing the research group into 'new', 'old' and 'transferred' patients we were able to examine in which phase of treatment the largest changes in hkt-30 scores occurred.

RESULTS

More than half the scores for dynamic risk factors, as well as the total score, declined significantly as treatment progressed, but the differences were small in absolute terms. The three subgroups of patients hardly differed from each other with regard to the degree of change.

CONCLUSION

The scores for the risk factors, assumed in theory to be changeable, seemed to become lower as the treatment progressed. However, it is not yet certain whether these lower scores were in fact directly linked to a reduction on the risk of reoffending.

Aggression control therapy for violent forensic psychiatric patients: method and clinical practice

Aggression control therapy is based on Goldstein, Gibbs, and Glick's aggression replacement training and was developed for violent forensic psychiatric in- and outpatients (adolescents and adults) with a (oppositional-defiant) conduct disorder or an antisocial personality disorder. First, the conditions for promoting "treatment integrity" are examined. Then, target groups, framework, and procedure are described in detail, followed by the most important clinical findings during the period 2002 to 2006. Finally, new programme developments are mentioned, with aggression control therapy as a starting point.

Development of the Observation Scale for Aggressive Behavior (OSAB) for Dutch forensic psychiatric inpatients with an antisocial personality disorder

The Observation Scale for Aggressive Behavior (OSAB) has been developed to evaluate inpatient treatment programs designed to reduce aggressive behavior in Dutch forensic psychiatric patients with an antisocial personality disorder, who are "placed at the disposal of the government". The scale should have the sensitivity to measure changes in the possible determinants of aggressive behavior, such as limited control of displayed negative emotions (irritation, anger or rage) and a general deficiency of social skills. In developing the OSAB 40 items were selected from a pool of 82 and distributed among the following a priori scales: Irritation/anger, Anxiety/gloominess, Aggressive behavior, Antecedent (to aggressive behavior), Sanction (for aggressive behavior) and Social behavior. The internal consistency of these subscales was good, the inter-rater reliability was moderate to good, and the test-retest reliability over a two to three week period was moderate to good. The correlation between the subscales Irritation/anger, Anxiety/gloominess, Aggressive behavior, Antecedent, Sanction was substantial and significant, but the anticipated negative correlation between these subscales and the Social behavior subscale could not be shown. Relationships between the corresponding subscales of the OSAB and the FIOS, used to calculate concurrent validity, yielded relatively high correlations. The validity of the various OSAB subscales could be further supported by significant correlations with the PCL-R and by significant but weak correlations with corresponding subscales of the self-report questionnaires. The Observation Scale for Aggressive Behavior (OSAB) seems to measure aggressive behavior in Dutch forensic psychiatric inpatients with an antisocial personality disorder reliably and validly. Contrary to expectations, a negative relationship was not found between aggressive and social behavior in either the OSAB or FIOS, which were used for calculating concurrent validity.

An adapted version of the Rosenzweig Picture-Frustration Study (PFS-AV) for the measurement of hostility in violent forensic psychiatric patients

BACKGROUND

The original Rosenzweig Picture-Frustration Study (PFS), designed to measure reactive aggressive behaviour in adults, contains 24 pictures of ambiguous situations in which someone is making a remark that can be interpreted as provocative.

AIM

An adapted version of Rosenzweig's PFS (PFS-AV) was developed to assess the hostile thoughts elicited by interpersonal frustrating situations in forensic psychiatric patients with a conduct disorder or an antisocial personality disorder.

METHODS

Patients were asked to give their responses in a few words on paper, which were then evaluated for hostility using a seven-point Likert scale. The patients also completed questionnaires on personality and on aggressive and socially competent behaviour.

RESULTS

Twelve of the 24 pictures that had a good internal consistency, inter-rater reliability, and test-retest reliability were selected. In support of the instrument's concurrent validity, scores on the PFS-AV were positively correlated with those on the aggressive behaviour questionnaires but less strongly than the correlations between the aggressive behaviour questionnaires mutually. The validity of the PFS-AV was demonstrated by the positive correlation between PFS-AV hostility and neuroticism, and by the negative correlation with extraversion, openness, agreeableness and conscientiousness. A relatively low but positive correlation was found with social anxiety and a negative correlation was found with social skills in situations where approaching behaviour may be exhibited.

CONCLUSION

The adapted version of the PFS-AV appears reliably and validly to measure hostility in violent forensic psychiatric patients.

Aggression of Psychiatric Patients Associated with the Use of As-needed Medication

INTRODUCTION

Previous studies showed that aggression is an important reason to prescribe as-needed medication. The objective of this study was to compare the use of as-needed medication in aggressive and non-aggressive psychiatric patients and to explore patterns of administration of as-needed medication around aggressive incidents.

METHODS

An observational study in three psychiatric wards was conducted. Incidence densities of as-needed medication were determined for aggressive and non-aggressive patients and expressed as incidence density ratios [IDRs]. Intensity of as-needed medication used before and following aggressive incidents were determined within a 48-hours time-window.

RESULTS

Aggressive patients had an increased use of both psychotropic and somatic as-needed medication (IDR, 2.5; 95% CI, 2.2-2.7 and IDR, 2.1; 95% CI, 1.8-2.4, respectively). Of the psychotropic medication for aggressive patients, 15% was administered in a time-window of 48 hours around an aggressive incident; in this time-window more as-needed medication was administered following an aggressive incident compared to earlier treatments.

CONCLUSION

An increased use of both psychotropic and somatic as-needed medication is associated with aggressive behavior. Psychotropic as-needed medication is more frequently administered shortly after an aggressive incident than shortly before. However, more often as-needed medication is administered outside the 48 hours time-window around an aggressive incident.

Are patients' views on seclusion associated with lack of privacy in the ward?

The lack of single-bed rooms in psychiatric wards may reduce the possibility of patients getting sufficient rest and privacy and may increase their risk of being overstimulated. This study explored whether residing in single- versus multiple-bed rooms in a psychiatric ward was associated with psychiatric patients' opinions about seclusion. More specifically, it was studied whether patients who had shared a room with other patients prior to seclusion rated seclusion more favorably. It was thought that they would rate seclusion more favorably due to the lack of rest they previously experienced in their regular room. For this, the Patient View-of-Seclusion Questionnaire of Hammill, McEvoy, Koral, and Schneider [Hammill, K., McEvoy, J., Koral, H., & Schneider, N. (1989). Hospitalized schizophrenic patient views about seclusion. Journal of Clinical Psychiatry, 50, 174-177] was completed by 54 secluded adult patients hospitalized in a locked ward of a Dutch psychiatric hospital. A significant association was found between residing in multiple-bed rooms prior to seclusion and a less negative view on seclusion. This finding suggests that the ward environment may have a rather large impact on how seclusion is perceived. The results underline the need for single-bed rooms in the treatment of psychiatric inpatients.

Pharmacotherapy for the treatment of aggressive behavior in general adult psychiatry: A systematic review

OBJECTIVE

To systematically review the evidence for pharmacologic management of outwardly directed aggressive behavior in general adult psychiatry.

DATA SOURCES

Literature searches in PubMed, EMBASE, PsycINFO, and Cochrane libraries from 1966 through March 2005 were used to identify relevant studies. The keywords aggression, violence, anger, and hostility combined with drug therapy, psychotropic drugs, adrenergic beta-antagonists, anticonvulsants, anti-depressants, antipsychotic agents, benzodiazepines, and lithium were searched. Furthermore, the retrieved publications were searched for additional references.

STUDY SELECTION

All randomized controlled trials addressing pharmacotherapy for aggression or aggression-related symptoms were included, except studies addressing the "emergency situation" and studies conducted in specialized psychiatric or non-psychiatric settings.

DATA EXTRACTION

Evidence synthesis was performed using the "best-evidence principle." Two authors independently adjudicated methodological quality and generalizability to daily clinical practice.

DATA SYNTHESIS

Thirty-five randomized controlled trials met the inclusion criteria and were evaluated. On the basis of a best-evidence synthesis model, weak evidence for antiaggressive effects of antipsychotics, anti-depressants, anticonvulsants, and beta-adrenergic-blocking drugs was found. Atypical antipsychotics appeared superior to typical antipsychotics. The use of various outcome measures and insufficient data reporting in the individual studies hampered the quantitative assessment of efficacy across studies. Further limitations of the available randomized controlled trials included small sample sizes, short study duration, and poor generalizability to daily clinical practice setting.

CONCLUSIONS

Whereas pharmacotherapy is frequently applied in aggressive patients, only weak evidence of efficacy of various drug classes was found. Consensus about the use of aggression measurement scales in clinical trials is necessary for future research. Furthermore, large-scale trials with more naturalistic designs, as opposed to classical randomized controlled trials with strict inclusion and exclusion criteria, may be advisable in order to obtain results that are more generalizable to daily clinical practice.

A model of aggression in psychiatric hospitals

OBJECTIVE

Research of the determinants of inpatient aggression indicates that certain environmental hospital variables play a role in triggering aggression in psychiatric hospitals. Yet, how patient, staff and ward variables interact in eliciting aggression is not well understood.

METHOD

On the basis of earlier findings, a model was proposed in which psychopathology and distorted cognitions of the patient are combined with environmental and communicational stressors that are specific for psychiatric wards.

RESULTS

The proposed model elucidates how certain patient, staff and ward characteristics may interact in causing aggression. The model also emphasizes that repeated inpatient aggression may be the result of a vicious circle, i.e. inpatient violence is often followed by an increase in environmental and/or communication stress on the patient, thereby heightening the risk of a repeated outburst of violence.

CONCLUSION

Although tentative, the model may shed light on the mechanisms that lead to (repeated) violence.

Evaluation of a cognitive-behavioral program for chronically psychotic forensic inpatients

The present study evaluated the progress of four groups of chronically psychotic patients in treatment at De Kijvelanden Forensic Psychiatric Hospital. The psychotic patients were offered a cognitive-behavioral program, including psycho education, grief processing, stress management, functional training, coping with psychotic symptoms (Liberman module) and social skills training. Nine patients dropped out of the program. Sixteen patients who completed it scored significantly better than a control group of 16 psychotic patients, who had not yet participated in the program, on the "social skills" and "negative coping behavior" subscales of one of two observation scales used. On the other observation instrument (REHAB), however, no significant improvement in the general level of functioning was found in the group of treated patients, as compared to the control group. Apart from these two observation scales, the PANSS (structured interview for positive, negative and general psychopathological symptoms) and the SIG (self-report questionnaire for social anxiety and social responses) were used to evaluate treatment progress. Significant improvements were not found on these scales, except for a slight positive effect on the PANSS negative symptoms scale. These results illustrate the difficulties and limitations of treating chronically psychotic offenders, who often also suffer from cluster B personality disorders.

Fifteen years of research with the Staff Observation Aggression Scale: a review

OBJECTIVE

Research on the prevalence and causes of in-patient aggression has been hindered by the use of different methods for measuring aggression. Since Palmstierna and Wistedt presented the Staff Observation Aggression Scale (SOAS) in 1987, this data collection method has been used in various studies, which may make comparisons more useful.

METHOD

Studies with SOAS aggression data were compiled using MEDLINE, the Internet, and references from SOAS papers.

RESULTS

Reviews of studies on psychometric properties suggest fair to good inter-rater reliability and validity for SOAS assessments. The number of aggressive incidents per patient per year found on acute admissions wards (n = 38) considerably varied, with a range of 0.4-33.2 incidents (mean = 9.3).

CONCLUSION

Although the aggression data included in the present review were obtained in highly comparable ways, substantial differences in aggression rates between wards were still found. Some countries (e.g. the Netherlands) appear to have a relatively high incidence of aggression on acute wards.
