Disturbing behavior: a study of incident reports

Aggressive behaviour among mentally handicapped females in a closed villa

Minor aggression is common in a closed female villa in a hospital for the mentally handicapped. In this study it occurred most frequently between 8a.m. and 10p.m. with a lunch-time peak. More incidents occurred on Saturday than on any other day. Few of the patients were psychotic and incidents were related to meal-times and reduced supervision. The most common targets for aggressive behaviour were property and the patient herself. The most common locus for aggression was outside the Sister's office. Attention to improving communication skills and providing more supervision should help to reduce the level of aggression.

Panic-agoraphobic spectrum and light sensitivity in a general population sample in Italy

OBJECTIVE

This study aimed to verify a possible correlation between panic symptoms and photosensitivity, not only in panic disorder (PD) but also in the panic-agoraphobic spectrum.

METHOD

One hundred and sixty-nine healthy and drug-free subjects completed the Structured Clinical Interview for Panic-Agoraphobic Spectrum-Lifetime version (SCI-PAS-Lifetime) and the Photosensitivity Assessment Questionnaire (PAQ).

RESULTS

The SCI-PAS-Lifetime total score was positively correlated with the total score of the PAQ photophobia subdimension (r = 0.44; P < 0.001); the SCI-PAS-Lifetime total score was not significantly correlated with the photophilia subdimension. As photophobia increased, we observed significant score increases in all SCI-PAS-Lifetime domains. Bivariate correlation showed higher coefficient correlation between the panic-like symptoms domain and photophobia (r = 0.44; P < 0.001).

CONCLUSIONS

A high total score in the SCI-PAS-Lifetime, which denotes more typical features of the spectrum, is associated with a higher level of light sensitivity and intolerance toward bright stimuli. This finding reflects clinical evidence that widely documents photophobic behaviours in subjects with PD and the importance of light stimuli exposure during the onset and course of such a disorder. Bright stimulation seems to be relevant both in PD diagnosed according to current DSM criteria and in the entire panic-agoraphobic spectrum, from nuclear elements of the disorder through subclinical states to the normal condition.

Risk factors for violence among long-stay psychiatric patients: national study

This study identified risk factors for violence among long-stay (1 year or more) psychiatric patients in Israel (n = 2946) using data from a national reevaluation of such patients. Patients were rated as being violent if hospital staff or patient charts indicated an incident of physical violence at least every few months. The relationship between violence and patients' functioning, living conditions, treatment, background and hospitalization history was studied. In total, 22.8% of patients were violent. Based on logistic regression analysis, the risk factors for being violent were younger age, younger age at first hospitalization, poorer self-care, having more frequent visitors, and the patient not having his or her own clothing. The data for age and lack of gender differences confirm previous findings. However, the results regarding clothing, visitors, poor self-care and age of onset are unique. The results of this study suggest that the violent behaviour of in-patients is related to both individual and environmental variables.

Violent incidents in an adolescent forensic unit

Violent incidents in psychiatric institutions have been the focus of much study over the past few decades. But there has been little work looking at similar incidents in child and adolescent units. The authors set out to examine whether some of the patterns observed in adult populations are true of adolescent groups. The Gardener Unit was considered appropriate in light of reports of a higher frequency of assaultative behaviour among younger clients and because of the nature of problems presented by clients needing a secure environment. All violent incidents are automatically recorded. The violent incident register was examined between 1 June 1991 and 1 June 1992 and the information cross-checked with case notes and nursing reports. Demographic details, etc. were obtained from case notes. The results indicated a slightly higher daily incident rate than adult studies. At least half of the population were involved in some form of violent episode over the 12-month period. The majority of incidents were minor in nature. Nursing staff were the most frequent targets, although females showed an excess of inwardly directed aggression (self harm). A prior history of violent behaviour did not serve as a realistic predictor of frequency of violent incidents in this study. With increasing concern regarding the care of this disturbed group of young people, it was felt important to look closely at the nature of and handling of violent incidents on this unit. A second paper will consider in detail how these incidents were dealt with.

The measurement of aggression and violence in hospitalized psychiatric patients

Aggression and violence are significant clinical problems in psychiatric inpatient units. However, research exploring violent behavior is limited by the lack of an adequate research scale. This paper reports on the development and testing of the Violence Scale (VS), a behavioral rating scale which measures aggressive and violent behavior towards self, others and property. The VS has been tested in two studies of psychiatric inpatients (N = 162) and (N = 42). Tests of reliability included internal consistency, item analysis and stability. Tests of validity included content and construct validity. The psychometric results were evaluated through the application of standard statistical criteria [Carmines, E. G. and Zeller, R. A. (1979). Reliability and Validity Assessment. Sage University Press, Beverly Hills, CA; Cronbach, L. J. (1951). Coefficient alpha and the internal structure of tests. Psychometrika 16, 197-333; Nunnally J. (1978). Psychometric Theory, McGraw-Hill, New York]. Coefficient alpha was 0.91 (study 1) and 0.68 (study 2) and stability was r = 0.79 (study 1). The items met most of the established criteria for item analysis and internal consistency. In factor analysis, the items met the criteria for loading onto the three predicted factors (others, self and property). Results of predictive model testing indicated that three of the four predicted relationships were supported. Initial testing indicates the scale is moderately stable, is internally consistent, and has evidence of initial limited construct validity.

A prospective study of patient assaults on nurses in a provincial psychiatric hospital in Canada

A 27-month prospective study was conducted of patient assaults on nurses in a Canadian psychiatric hospital. Rates were low (4% of the patients committing an assault) and the injuries mostly trivial. Schizophrenics accounted for 43% of attacks, but when allowance was made for the disproportionate number of patients in the hospital with this diagnosis, individuals with mental retardation or dementia were approximately twice as likely to be assaultive as schizophrenics. Repeat assaulters (greater than 4 attacks) were more likely to be suffering from paranoid schizophrenia.

A prospective study of patient assaults on nursing staff in a psychogeriatric unit

A 27 month prospective study concerned with aspects of patient-nurse assaults on the geriatric unit (three wards) of a Canadian provincial mental hospital was conducted. The findings were compared with those for the other words. The incidence of assaults was approximately the same in both areas (0.24-0.25 assaults/occupied bed/year respectively). In the former, the commonest diagnoses associated with assaultiveness were dementia followed by schizophrenia and in the rest of the hospital, schizophrenia. However, when base rates of assaultiveness were calculated allowing for the disproportionate number of patients with these conditions, mental retardation, and dementia were approximately twice as likely to be related to assaultiveness as schizophrenia; regardless of where the patients were located. In the geriatric unit attacks were more likely when patients were being physically guided or led and during the administration of drugs; elsewhere whilst physical restraints were being applied. In both hospital areas a comparatively small number of patients accounted for a disproportionate number of assaults and a few nurses were attacked repeatedly. The majority of episodes were trivial but in isolated cases personnel were off work for several months. The discussion focuses on the possibility of generalizing results.

Theoretical modeling to predict violence in hospitalized psychiatric patients

Research from a nursing perspective on factors related to psychiatric inpatient violence is lacking. The purpose of the study was to test a nursing theoretical framework of violence using predictive model testing. Data were collected by 57 nursing staff on 162 hospitalized patients in four hospitals. Inconsistencies in the social and therapeutic rules predicted 18% of the violent behavior. Demographic and medical variables contributing to violence were: history of violence towards others, length of hospitalization, and the diagnosis of substance abuse. The findings support the need for further research to identify nursing concepts that contribute to patient violence.

Frontal cerebral lesions and violent incidents in chronic neuropsychiatric patients

The contribution of selected neurological, psychiatric, and demographic variables to the frequency of violent incidents was studied in an institutional context. A multiple regression procedure was used to predict the number of documented incidents for each of 45 neuropsychiatric patients. This procedure yielded a 5-variable equation that accounted for close to a third of the variance. The first three variables entered each contributed uniquely to validity. These variables were presence of focal frontal cerebral lesions, number of inpatient days, and history of seizure disorder. The presence of cerebral damage in general did not predict violent incidents. The results are discussed in terms of possible brain-behavior relationships and the nature of the patient population.

A preliminary study of violent incidents in a special hospital (Rampton)

A six-month prospective study of violent incidents was carried out in a Special Hospital (Rampton). Comparisons were made with results from earlier studies in general psychiatric hospitals. As might be expected, incidents occurred more frequently in the Special Hospital. These incidents were also more serious in nature and resulted in greater injury. Although more patients in the Special Hospital were involved in incidents, only a small number of patients accounted for the majority of these. Female patients, who comprised 25% of the Special Hospital population, were involved in 75% of the incidents. Nursing staff were three times as likely to be assaulted as patients.

Clinical and demographic characteristics of 15 patients with repetitively assaultive behavior

The 15 patients with the highest numbers of assaultive incidents over a one year period in a state mental hospital were identified and information collected regarding a variety of clinical and demographic characteristics. The results showed a group of patients who are relatively young, manifest severe symptomatology that is generally unresponsive to treatment, and have now been hospitalized continuously for greater than four years. The patients experienced the onset of symptoms as teenagers in most cases, showed poor psychosocial adjustment beyond childhood, and had positive family histories for mental illness or alcohol abuse. Patients with psychotic disorders predominated and tended to have positive symptoms rated as severe to very severe on the Global Rating Scale for Psychosis. Patients with nonpsychotic or personality disorders always showed a high frequency of self-injurious behavior in addition to their aggressive behavior toward others. A number of patients had a history of head trauma with EEG abnormalities. This information provides a starting point for subsequent studies examining potential distinctions between this subpopulation of patients and others, the motivation and circumstances of such incidents, and the interaction between the behaviors and their effects on those around them.

Mental disorder and dangerousness

Psychiatrists are called upon to make judgements on the future dangerousness of mentally disordered subjects in civil commitment procedures, in the criminal courts, and during the decision process on the release of offenders on indeterminate sentences or committals. The ability of psychiatrists to make these judgements is increasingly under challenge. The difficulties of making useful predictions when the base rate for the event to be predicted is low, is now well recognised. Less obvious are the problems attendant upon making socially useful predictions on psychiatric grounds in populations with a high base rate for future offending. The evidence pertaining to the level of violence amongst the mentally disordered is reviewed. The lesson to be drawn from the empirical evidence is that mental abnormality of and in itself contributes little to the prediction of the predisposition to act violently. The question remains as to whether there are definable groups or classes within the generality of mentally abnormal individuals for whom there is an increased risk of future violence. It would be compatible with both the research studies and common clinical impression if the mentally abnormal contained subgroups with unusually violent predispositions balanced by larger groups with less than average propensities to aggression. The literature is largely inadequate to delineate such high risk groups with the degree of certainty ideally needed to instruct clinical decisions, but does suggest that such groups exist and are capable of further empirical definition.
