Hostile attributional biases in severely aggressive adolescents.

128 adolescent boys (aged 14 yrs 2 mo to 19 yrs) from a maximum security prison for juvenile offenders were administered a task to assess hostile attributional biases. As hypothesized, these biases were positively correlated with undersocialized aggressive conduct disorder (as indicated by high scores on standardized scales and by psychiatric diagnoses), with reactive-aggressive behavior, and with the number of interpersonally violent crimes committed. Hostile attributional biases were found not to relate to nonviolent crimes or to socialized aggressive behavior disorder. These findings held even when race and estimates of intelligence and socioeconomic status (SES) were controlled. These findings suggest that within a population of juvenile offenders, attributional biases are implicated specifically in interpersonal reactive aggression that involves anger and not in socialized delinquency.

Pathways to childhood depressive symptoms: The role of social, cognitive, and genetic risk factors.

Childhood depressive conditions have been explored from multiple theoretical approaches but with few empirical attempts to address the interrelationships among these different domains and their combined effects. In the present study, the authors examined different pathways through which social, cognitive, and genetic risk factors may be expressed to influence depressive symptoms in 300 pairs of child twins from a longitudinal study. Path analysis supported several indirect routes. First, risks associated with living in a step- or single-parent family and punitive parenting did not directly influence depressive outcome but were instead mediated through maternal depressive symptoms and child negative attributional style. Second, the effects of negative attributional style on depressive outcome were greatly exacerbated in the presence of precipitating negative life events. Third, independent of these social and cognitive risk mechanisms, modest genetic effects were also implicated in symptoms, with some indication that these risks are expressed through exposure to negative stressors. Together, these routes accounted for approximately 13% of total phenotypic variance in depressive symptoms. Theoretical and analytical implications of these results are discussed in the context of several design-related caveats. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Desensitization to media violence: Links with habitual media violence exposure, aggressive cognitions, and aggressive behavior.

This study examined the links between desensitization to violent media stimuli and habitual media violence exposure as a predictor and aggressive cognitions and behavior as outcome variables. Two weeks after completing measures of habitual media violence exposure, trait aggression, trait arousability, and normative beliefs about aggression, undergraduates (N = 303) saw a violent film clip and a sad or a funny comparison clip. Skin conductance level (SCL) was measured continuously, and ratings of anxious and pleasant arousal were obtained after each clip. Following the clips, participants completed a lexical decision task to measure accessibility of aggressive cognitions and a competitive reaction time task to measure aggressive behavior. Habitual media violence exposure correlated negatively with SCL during violent clips and positively with pleasant arousal, response times for aggressive words, and trait aggression, but it was unrelated to anxious arousal and aggressive responding during the reaction time task. In path analyses controlling for trait aggression, normative beliefs, and trait arousability, habitual media violence exposure predicted faster accessibility of aggressive cognitions, partly mediated by higher pleasant arousal. Unprovoked aggression during the reaction time task was predicted by lower anxious arousal. Neither habitual media violence usage nor anxious or pleasant arousal predicted provoked aggression during the laboratory task, and SCL was unrelated to aggressive cognitions and behavior. No relations were found between habitual media violence viewing and arousal in response to the sad and funny film clips, and arousal in response to the sad and funny clips did not predict aggressive cognitions or aggressive behavior on the laboratory task. This suggests that the observed desensitization effects are specific to violent content. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

The treatment of mentally disordered offenders.

However narrowly defined, mentally disordered offenders (MDOs) are heterogeneous in demographics, diagnoses, offense characteristics, risk, and clinical needs. Treatment planning for MDOs should begin with an assessment of risk of future violent behavior in the community and risk of violence toward self or others inside an institution. Purposes of treatment among MDOs include treatments both to reduce risk of future violence and to alleviate the mental disorder. Relevant outcome measures include criminal and violent behavior, psychiatric symptomatology, admission to correctional or psychiatric facility, and quality of life. Clinical problems include aggression and problems of institutional management, criminal propensity, life skills deficits, substance abuse, active psychotic symptoms, social withdrawal, and depression. Because evidence relating them to risk of future violence is highest for the first 4 problems, it is argued that inpatient treatments should especially target them. Whenever risk levels and legal circumstances permit, community treatment is to be preferred. Sex offenders are discussed as a group for whom specialized services are indicated.… (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Attributional style as a risk marker of genetic effects for adolescent depressive symptoms.

Genetic effects on adolescent depression have been consistently reported, but little is known about mediating pathways from the distal genotype to resultant behavioral symptoms. Identifying intermediate risk markers may provide clues on these pathways. In the present study, longitudinal twin and sibling data were used to address 3 issues pertaining to attributional style as a putative marker of genetic risk for adolescent depression: state independence by assessing predictive effects between attributional style and depressive symptoms, heritability of attributional style at different time points, and genetic links between attributional style and depressive symptoms characterizing concurrent and longitudinal associations. The authors further examined whether these predictive and genetic links varied across levels of stress, age, and gender. Negative attributions preceded, co-occurred with, and followed symptoms. The predictive association between earlier negative attributions and later depressive symptoms did not differ by stress, age, or gender. Attributional style was moderately heritable at both time points. Genetic links with concurrent and prospective depressive symptoms were larger in individuals reporting higher levels of stress, who were older and female. Implications for attributional style as a marker reflecting genetic risks are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Comparison of cognitive models of depression: Relationships between cognitive constructs and cognitive diathesis–stress match.

The authors examined the relationship between the cognitive components of the Beckian and Hopelessness models of depression by administering measures of dysfunctional attitudes, attributional style, and life stress to a sample of 59 depressed adults. Confirmatory factor analyses indicated that dysfunctional attitudes and attributional style load on separate factors as opposed to a single factor. Additional analyses revealed that depressed persons conforming to diathesis-stress criteria according to each model were largely independent of one another. Results supported the conclusion that the Beckian and Hopelessness models of depression describe distinct cognitive constructs and refer to distinct subsets of depressed persons.

Social–cognitive mediators of the association between community violence exposure and aggressive behavior.

There is increased awareness that exposure to violence in the community can influence students’ aggressive behavior at school; however, less is known about the mechanisms that mediate this process. Having an enhanced understanding of how community violence exposure relates to students’ aggressive behavior at school may inform the use of preventive interventions aimed at reducing school violence. Consistent with social–cognitive theory, the current study tested whether the association between exposure to community violence and teacher-reported aggressive behavior was mediated by biased social information processing. Data on 184 suburban adolescents and their teachers were analyzed with structural equation modeling. Community violence exposure and aggressive behavior in the classroom were significantly related and mediated by negatively biased social–cognitive factors. Results suggest that even relatively low levels of community violence exposure may increase the risk of students displaying aggressive behavior at school. Although gender differences were explored, social information processing appeared to be an important mediator for both boys and girls.

Managing the violent patient: A guide for psychologists and other mental health professionals.

Being threatened, harassed, attacked, or confronted by a patient with a weapon is becoming more common and is likely to occur at some point in a mental health professional's career. Effective violence management programs can reduce the incidence of violence. Yet, few resources have been provided to assist psychologists and other mental health professionals to deal with aggressive patients. The authors offer strategies for the management of aggressive behavior that can be implemented to empower practitioners to take precautions when necessary in a quick and efficient manner when dealing with violent and potentially violent patients.

Violence and aggression in psychiatric units

OBJECTIVE: To help predict aggressive and violent behaviors, the frequency and types of these behaviors in acute psychiatric inpatient settings were examined, and potential interactions between staffing and patient mix and rates of the behaviors were explored. METHODS: Data on violent incidents were gathered prospectively in three adult acute psychiatric units in a general hospital and two units in a primary psychiatric hospital in Sydney, Australia. Staff recorded violent and aggressive incidents, which were ranked on an 8-level scale. They also completed weekly reports of staffing levels and patient mix. Poisson regression analysis was used to calculate relative rates, 95 percent confidence intervals, and p values. RESULTS: A total of 1,289 violent incidents were recorded over a seven-month period. Based on the scale, 58 percent of the incidents were serious. Seventy-eight percent were directed toward nursing staff. Complex relationships between staffing, patient mix, and violence were found. Relative risk increased with more nursing staff (of either sex), more nonnursing staff on planned leave, more patients known to instigate violence, a greater number of disoriented patients, more patients detained compulsorily, and more use of seclusion. The relative risk decreased with more young staff (under 30 years old), more nursing staff with unplanned absenteeism, more admissions, and more patients with substance abuse or physical illness. In total these factors accounted for 62 percent of the variance in violence. CONCLUSIONS: Violent incidents in psychiatric settings are a frequent and serious problem. Incidents appear to be underreported, and the seriousness of an incident does not guarantee it will be reported.     

The relationship between confidence and accuracy in clinical assessment of psychiatric patients' potential for violence

The authors studied the relationship between confidence and accuracy in clinical assessments of psychiatric patients' short-term risk of violence. At the time of entry to the hospital, physicians (N = 78) estimated the probability that each of 317 patients would physically attack other people during the first week of psychiatric hospitalization. The clinicians also indicated the degree of confidence they had in their estimates of violence potential. Nurses rated the occurrence of inpatient physical assaults with the Overt Aggression Scale. The results showed that when clinicians had a high degree of confidence, their evaluations of risk of violence were strongly associated with whether or not patients became violent. At moderate levels of confidence, clinicians' risk estimates had a lower, but still substantial relationship with the later occurrence of violence. However, when clinicians had low confidence, their assessments of potential for violence had little relationship to whether or not the patients became violent. The findings suggest that the level of confidence that clinicians have in their evaluations is an important moderator of the predictive validity of their assessments of patients' potential for violence.     

The effect of video game competition and violence on aggressive behavior: Which characteristic has the greatest influence?

Objective: This study is the first to our knowledge to isolate the effect of video game violence and competitiveness on aggressive behavior. Method: In Pilot Study 1, a violent and nonviolent video game were matched on competitiveness, difficulty, and pace of action, and the effect of each game on aggressive behavior was then compared using an unambiguous measure of aggressive behavior (i.e., the Hot Sauce Paradigm) in Experiment 1. In Pilot Study 2, competitiveness was isolated by matching games on difficulty and pace of action, and systematically controlling for violence. The effect of video game competition on aggressive behavior was then examined in Experiment 2. Results: We found that video game violence was not sufficient to elevate aggressive behavior compared with a nonviolent video game, and that more competitive games produced greater levels of aggressive behavior, irrespective of the amount of violence in the games. Conclusion: It appears that competition, not violence, may be the video game characteristic that has the greatest influence on aggressive behavior. Future research is needed to explore the mechanisms through which video game competitiveness influences aggressive behavior, as well as whether this relation holds in the long-term.

Cognitive aspects of chronic depression.

Previous research on chronic depression has focused on its link with other mood disorders and Axis II personality disorders. However, there are few data examining whether the cognitive perspective applies to this condition. In this cross-sectional study, 42 outpatients with chronic depression were compared with 27 outpatients with nonchronic major depressive disorder and 24 never psychiatrically ill controls on cognitive variables thought to be related to vulnerability to depression (e.g., dysfunctional attitudes, attributional style, a ruminative response style, and maladaptive core beliefs). Both depressed groups were more elevated than a never-ill comparison group. However, chronically depressed individuals were generally more elevated on measures of cognitive variables than those with major depressive disorders even after controlling for mood state and personality disorder symptoms.

Attributions for positive life events predict recovery from depression among psychiatric inpatients: An investigation of the Needles and Abramson model of recovery from depression.

The authors investigated whether attributions for positive life events predict decreases in hopelessness and depressive symptoms among clinically depressed adults. Measures of attributional style, attributions for recent events, depressive symptoms, dysfunctional attitudes, hopelessness, and life events were administered to 52 depressed psychiatric inpatients treated with antidepressant medication; the measures were readministered 12 and 24 days later. Results indicated that (a) internal, stable, global attributions for recent positive events mediated a significant association between attributional style for positive life events and decreased hopelessness; (b) decreases in hopelessness mediated a significant association between internal, stable, global attributions for recent positive events and decreases in depressive symptom levels; and (c) depressotypic cognitions were not associated with decreases in either hopelessness or depressive symptom levels.

Social-cognitive processes of severly violent, moderately aggressive, and nonaggressive boys.

Examined social–cognitive processes of aggressive and nonaggressive boys at preadolescent and early adolescent age levels. The social-cognitive variables included processing of cues, attributions, social problem solving, affect labeling, outcome expectations, and perceived competence and self-worth. Results indicated that a wide range of social-cognitive processes is distorted and deficient for violent and moderately aggressive children, and that different types of social cognition contribute unique variance in discriminating among groups. Severely violent boys at both age levels had difficulties with cue recall, attributions, social problem solving, general self-worth, and a pattern of endorsing unusually positive affects that they may experience in different settings. Moderately aggressive boys shared some of the social-cognitive difficulties demonstrated by severely violent boys, but they also displayed indications that their aggression may be more planfully aimed to achieve expected outcomes. When the moderately aggressive and the violent boys differed from the nonaggressive boys on attributional biases and low perceived self-worth, a continuum existed with violent boys displaying more extreme social-cognitive dysfunctions than the moderately aggressive boys.

Use of the Buss-Durkee Hostility Inventory among British prisoners.

Administered the Buss-Durkee Hostility Inventory to a group of long-term prisoners, many of whom had committed violent crimes. Results do not confirm a relationship between Buss-Durkee Total Hostility scores and violence among prisoners and suggest that the inventory measures aggressive attitudes rather than behavior.

Mental illness and violence: an epidemiological appraisal of the evidence

OBJECTIVE: To conduct a critical review of the literature on the matter of mental illness and violence, to examine whether there is enough evidence to establish a causal link, and to provide epidemiological background to measure the risk to the population. METHOD: Based on a computerized search of the literature on mental illness and violence previously conducted for Health Canada, studies in the area were critically reviewed and divided into 3 main categories: 1) studies of criminal and violent behaviour among psychiatric patients, 2) studies of psychiatric illness among offenders (prevalence studies in institutions, analytical studies, and community follow-up of offenders), and 3) epidemiological community-based studies on the issue of mental illness and violence (police-citizen encounters, representative samples, and other epidemiological studies). Causality rules and measures of risk were then applied to the evidence elicited. RESULTS: The review of the literature suggests that only a small minority of hospitalized patients, typically those suffering from acute psychotic symptoms, are involved in violent incidents. Formerly hospitalized patients are at a higher risk of committing violence if they are not properly treated and are experiencing threat/control-override psychotic symptoms. Substance abuse disorders significantly raise the risk for violence. Family members are the most at risk of being victimized. CONCLUSION: An association exists between mental illness and violence, but the many covariations that naturally affect the equation between them introduce uncertainties in establishing causality.     

Does television violence cause aggression?

In a previous study 3rd graders who preferred violent TV programs were rated more aggressive in school by peers. In a 10-yr follow-up, 211 males and 216 females of the original 875 Ss were interviewed as to their television habits and again rated their peers on aggressive behavior. It was found that the violence of programs preferred by male 3rd graders was even more strongly related to aggression 10 yr. later. Cross-lagged correlations, partial correlations, and multiple regression indicate a probable causative influence of watching violent TV programs in early formative years on later aggression. Although TV violence was not the only cause of aggressive behavior, its effect was relatively independent and explained a larger proportion of variance than any other single factor studied, e.g., IQ, social status, ethnicity, and parental disharmony.

The relationship between heart rate reactivity, emotionally aggressive behavior, and general violence in batterers.

This study examined the relationships among physiological responses during marital conflict, aggressive behavior, and violence in battering couples. As an index of physiological response, the authors used the male batterer's heart rate reactivity, assessed as the change from an eyes-closed baseline to the first 5 min of their marital conflict interaction. During marital interaction, violent husbands who lowered their heart rates below baseline levels were more verbally aggressive toward their wives. Wives responded to these men with anger, sadness, and defensiveness. The husbands were classified as Type 1 batterers. When compared to the remaining violent husbands (classified as Type 2 batterers), Type 1 men were also more violent toward others (friends, strangers, coworkers, and bosses), had more elevated scales reflecting antisocial behavior and sadistic aggression, and were lower on dependency than Type 2 men. The 2-year followup revealed a separation-divorce rate of 0 for marriages involving Type 1 men and a divorce rate of 27.5% for marriages involving Type 2 men.

Articulated thoughts of maritally violent and nonviolent men during anger arousal.

The cognitive correlates of anger arousal were investigated in community-based samples of maritally violent (MV), maritally distressed-nonviolent (DNV), and maritally satisfied-nonviolent (SNV) husbands. Participants performed the Articulated Thoughts in Simulated Situations (ATSS) paradigm while listening to anger-arousing audiotapes. Trained raters coded for irrational beliefs, cognitive biases, hostile attributional biases, and anger control statements. Results indicated that MV men articulated significantly more irrational thoughts and cognitive biases than DNV and SNV men. MV men articulated more hostile attributional biases than DNV and SNV men across all ATSS scenarios. SNV men, however, articulated more anger control statements during ATSS anger arousal than MV or DNV participants. Discriminant function analyses indicated that specific thoughts discriminated between the groups and differentiated mildly from severely violent Ss. ATSS cognitive distortions (a) were not correlated with questionnaire measures of cognitive distortion, and (b) were superior to questionnaire measures in discriminating between the groups. The findings are interpreted in light of recent advances in understanding the relationship between information processing, anger, and marital aggression.
