Aim: To address the need for additional education in the management of mental illness in the critical care setting by providing a broad overview of the interrelationship between critical illness and mental illness. The paper also offers practical advice to support critical care staff in managing patients with mental illness in critical care by discussing two hypothetical case scenarios involving aggressive and disorganised behaviour. People living with mental illness are over‐represented among critically unwell patients and experience worse outcomes, contributing to a life expectancy up to 30 years shorter than their peers. Strategic documents call for these inequitable outcomes to be addressed. Staff working in intensive care units (ICUs) possess advanced knowledge and specialist skills in managing critical illness but have reported limited confidence in managing patients with comorbid mental illness. Design & Methods: A discursive paper, drawing on clinical experience and research of the authors and current literature. Results: Like all people, patients with mental illnesses draw on their cognitive, behavioural, social and spiritual resources to cope with their experiences during critical illness. However, they may have fewer resources available due to co‐morbid mental illness, a history of trauma and social disadvantage. By identifying and sensitively addressing patients' underlying needs in a trauma‐informed way, demonstrating respect and maximising patient autonomy, staff can reduce distress and disruptive behaviours and promote recovery. Caring for patients who are distressed and/or display challenging behaviours can evoke strong and unpleasant emotional responses. Self‐care is fundamental to maintaining a compassionate approach and effective clinical judgement. Staff should be enabled to accept and acknowledge emotional responses and access support—informally with peers and/or through formal mechanisms as needed. Organisational leadership and endorsement of the principles of equitable care are critical to creation of the environment needed to improve outcomes for staff and patients. Relevance to clinical practice: ICU nurses hold an important role in the care of patients with critical illnesses and are ideally placed to empower, advocate for and comfort those patients also living with mental illness. To perform these tasks optimally and sustainably, health services have a responsibility to provide nursing staff with adequate education and training in the management of mental illnesses, and sufficient formal and informal support to maintain their own well‐being while providing this care. Patient and public involvement: This paper is grounded in accounts of patients with mental illness and clinicians providing care to patients with mental illness in critical care settings but there was no direct patient or public contribution.

This paper addresses the possible effects of psychedelic drugs, notably psilocybin, on moral bio‐enhancement (MBE). It will be argued that non‐psychedelic substances, such as oxytocin, serotonin/serotonin reuptake inhibitors, or vasopressin, have indirect effects on M(B)E, whereas psilocybin has direct effects. Additionally, morality and happiness have been shown to operate in a circularly supportive relationship. It will be argued that psilocybin also has more direct effects on the augmentation of human happiness than non‐psychedelic substances. Hence, psilocybin multiplies its effects on morality and on moral enhancement (as well as on happiness) if compared with non‐psychedelic substances. Still, caution is advised if psilocybin is being used, and the correct dosage should be prescribed by an appropriate physician. Furthermore, the use of psilocybin has additional effects on moral enhancement and happiness if combined with meditation, preferably under the guidance of an experienced meditation specialist.

The aim of this paper is to analyse approaches to issues of risk, responsibility and representations of violence in women social workers' conversations with alleged or confirmed violent fathers. The study adds to a growing body of research on agencies' handling of intimate partner violence (IPV) in the context of separation. Empirically, the study draws from 12 structured, audio recorded and transcribed interviews with support‐seeking and divorced fathers, from five municipalities in Sweden, conducted as part of a cooperation project in which a risk‐detection method (Family Law Detection Of Overall Risk Screen [FL‐DOORS]) was also tested. The results suggest a tension between different professional tasks. To validate information on IPV, detect risk and enhance a child perspective competes with other professional projects, most obviously with promoting cooperation between parents. The study confirms previous research, which demonstrates unique challenges facing women social workers and counsellors when working with men as perpetrators. In conclusion, the paper concurs with the call for a focus on responsibility and on safe parenting in professional conversations with allegedly or confirmed abusive fathers. [ABSTRACT FROM AUTHOR]

Aims: In the article, ancient concepts linking animals and wine are discussed. This paper provides a description of animals that in antiquity were considered to be especially fond of grapes and wine, as well as animals that were, for various reasons, given wine to drink by humans, and animals that in ancient literature had an averse association with wine. In the paper, the author attempts to answer the following questions, what was the conceptual framework for the tales about drunk animals? In what circumstances were observations of animals becoming inebriated conducted? Which animal species were considered as most susceptible to the effects of wine? Last, was wine believed to affect animals and humans in a similar way? Methods: Ancient literature provides a set of extant information about animals that willingly become inebriated with grapes or are given wine by humans, which deserves a separate analysis. The ancient authors commonly interspersed narration with information about the animals and invoked personal experiences of contact with the described animal and information obtained from those who had the opportunity to conduct 'zoological' observations or even medical experiments. Results: There is a large group of animals that appear in ancient accounts consuming alcohol in the form of fermented fruit and wine. The ancients held the mostly incorrect belief that snakes had an enormous predilection for wine; moreover, contemporary research confirms that, as the ancients rightly observed, insects and birds do display a fondness for fermented fruit and wine. It was correctly observed that an excess of wine induced extreme states, such as sleepiness and aggression in animals, in a manner similar to humans. Conclusions: Accounts in ancient literature show a close association between animals and wine existed among the Greeks and Romans. [ABSTRACT FROM AUTHOR]

The principles of least restrictive care and recovery‐focused practice are promoted as contemporary practice in the care of individuals with mental ill health, underpinning legislation concerning mental health and illness in many jurisdictions worldwide. Inpatient mental health units with locked doors are incompatible with this style of care and throwback to a time where care for mental illness was primarily custodial. The aim of this scoping review is to determine whether evidence exists for locking mental health unit doors, whether this practice is compatible with recovery‐focused care and to determine whether door locking has changed since a review conducted by Van Der Merwe et al. (Journal of Psychiatric and Mental Health Nursing, 16, 2009, 293) found that door locking was not the preferred practice in the management of acute mental health units. We used Arksey and O'Malley's (International Journal of Social Research Methodology: Theory and Practice, 8, 2005, 19) framework for scoping reviews, with our initial search locating 1377 studies, with screening narrowing final papers for inclusion to 20. Methodologies for papers included 12 using quantitative methodology, 5 qualitative and 3 that used mixed methods designs. Poor evidence was found for door locking to mitigate risks such as absconding, aggression or illicit substance importation. Furthermore, locked doors had a detrimental impact on the therapeutic relationship, nurse job satisfaction and intention to leave the profession. This scoping review indicates that research is urgently needed to address a mental healthcare culture where door locking is an entrenched practice. Studies of alternative approaches to risk management are required to ensure inpatient mental health units are truly least‐restrictive, therapeutic environments. [ABSTRACT FROM AUTHOR]

BACKGROUND: Youth violence, victimization, and bullying are pervasive in schools across the United States and are detrimental for learning and healthy development. K‐12 school safety is an increasingly urgent issue to research and understand from multiple perspectives. Physical and psychological safety in school is linked to better student and school outcomes and is fundamental to fostering well‐being and prosocial behavior. METHODS: Despite research demonstrating positive outcomes associated with school safety, there is no comprehensive conceptual model in the literature that considers precursors, strategies, mechanisms, and outcomes of school safety together. The current paper presents an equity‐centered comprehensive model of school safety, which is intended as a holistic representation of the multiple factors and pathways that contribute to school safety and positive youth development. RESULTS: This model can guide research and practice through an equity‐centered and comprehensive approach. This model can enable practitioners, researchers, and policymakers to make informed decisions and reach consensus regarding planning and decisions related to reducing violence and establishing supportive school environments. CONCLUSION: Our model suggests that a comprehensive approach can ensure the safety and well‐being of students and staff. By thinking ecologically, schools, communities, and stakeholders can ensure that all aspects of the school context are included in school safety. [ABSTRACT FROM AUTHOR]

Aim: Careful study and accurate description of behaviour are important to understand developmental challenges for individuals with Cornelia de Lange syndrome (CdLS). Here we present a systematic review of current understanding of behaviour in CdLS.Method: A systematic search was performed for articles published between January 1946 and December 2015 evaluating autism, self-injury, and/or cognition in CdLS. After study-selection, 43 papers were included. The Cochrane quality criteria were adjusted to assign quality scores to the included studies.Results: Participants were mostly categorized in the severe/profound developmental level. Methodology and quality were very heterogeneous, as well as reporting occurrence of autism. Self-injurious behaviour was reported in 15 papers. Physical conditions were reported in 21 studies, mostly related to hearing and vision. Only nine studies mentioned details about medication.Interpretation: Comparison of presented results was hindered by heterogeneous assessment methods. Improving our understanding of behavioural characteristics in CdLS requires more uniform methodology. We propose a criterion standard of instruments that can ideally be used in assessment of behaviour and development. This will improve understanding of behaviour in the context of developmental level and daily functioning. [ABSTRACT FROM AUTHOR]

Topic: Globally, the COVID‐19 pandemic had impacted the health care delivery including inpatient psychiatric facilities. Within psychiatric settings, life of inpatients was profoundly altered. Purpose: This paper aimed to understand if pandemic‐related changes within an inpatient Eating Disorder Unit in a specialized psychiatric hospital in Ontario, Canada impacted incidence of aggression and use of coercive methods among adolescents. Source Used: An exploratory study design was used to examine incidence of aggression, self‐harm, code whites, staff assist, restraints and seclusion, and nasogastric feeding (NGF) among adolescents with eating disorders before and after the modified service delivery within the inpatient unit. Descriptive analyses were conducted. Results: Analyses revealed a complete reduction in episodes of self‐harm, aggression, staff assists, use of restraint and seclusion as well as an 80.14% reduction on average use of NGF. Conclusion: Authors speculate that the change in environment and program delivery method, peer influence, and shift in power relations between patient and staff may have resulted in improved experiences. This report provides insights to adopt a recovery‐oriented service delivery for adolescents with eating disorders in inpatient settings. [ABSTRACT FROM AUTHOR]

Many children with aggressive behavior problems also suffer from anxiety. This cooccurrence may perhaps be explained by transdiagnostic factors. Identifying these factors seems crucial, as they may be important targets to treat these cooccurring problems effectively. This two‐study paper investigates whether hostile interpretation of others' intentions is a transdiagnostic factor for cooccurring aggression and anxiety problems, examining two samples of boys in middle childhood. We assessed boys' aggression and anxiety using teacher‐report in Study 1 (N = 84, Mage = 10.10), and parent‐report in Study 2 (N = 115, Mage = 10.55). In both studies, we assessed hostile interpretation using vignettes describing ambiguous provocations by peers. Both studies revealed a strong association between aggression and anxiety problems, underscoring the necessity to examine factors that can explain this cooccurrence. However, in neither study was this association reduced when we added hostile interpretation to the model, suggesting that hostile interpretation did not function as a transdiagnostic factor in our samples. One possible explanation for these findings is that hostile interpretation predicts both aggression and anxiety problems, but in different children. We, therefore, encourage scholars to conduct more research to explain the high comorbidity of aggression and anxiety problems in children. Future research should also examine hostile interpretation as predictor or transdiagnostic factor for aggression and anxiety problems in more diverse population, including girls and other age groups.

Non‐violent resistance (NVR) is a systemic approach to working with young people presenting with aggression and other harmful behaviours. The work draws on the use of personal presence in resistance movements of the twentieth century, focusing on the role of the caregiver to increase their presence through acts of resistance and care. This paper investigates the experiences of professionals using NVR in one UK residential care home. Eight participants took part in semi‐structured interviews, which were analysed thematically. Analysis identified four overarching themes: NVR is both a set of processes and a way of being, NVR and transformation, NVR and the personal–professional divide and NVR and organisational support. The findings suggest that NVR offers an effective and acceptable alternative to behavioural approaches. Further research is required to investigate the liminal role of the professional/parent and the challenge of managing reluctance both within and around the organisation. [ABSTRACT FROM AUTHOR]

Background: Violence exacts staggering personal and financial costs – a burden disproportionally born by adolescents and young adults. This may be partially due to an increased sensitivity to social rejection during this critical phase of development. Irritability, a transdiagnostic symptom, is often elicited by social interactions. Yet, little is known about age differences in social rejection‐elicited aggression and irritability. Progress toward testing such relations has been hindered by a lack of ecologically‐valid tasks that enable the measurement of in‐the‐moment social rejection‐elicited aggression. Methods: In this paper, we describe an initial study of young adults (n = 55) that demonstrates the efficacy of a novel Virtual School and Aggression Paradigm (VS‐AP). Next, we replicate these results in a second study of adolescents and young adults (ages 11–25 years; n = 173) and examine relations between social rejection‐elicited aggression, irritability, and age. Results: We found that aggressive behavior in the VS‐AP differed for accepting, rejecting, and unpredictable peer types (Study 1: F(2, 108) = 20.57, p <.001, ε2 =.28; Study 2: F(2, 344) = 152.13, p <.001, ε2 =.47), demonstrating that the VS‐AP successfully models social rejection‐elicited aggression. In Study 2, age was negatively correlated with aggressive behavior (r = −.29, p <.001) and irritability (r = −.28, p <.001), while irritability was positively correlated with aggressive behavior (r =.28, p <.001). Age moderated the relation between social rejection‐elicited aggression and irritability. Specifically, irritability was more predictive of aggression in young adults than in adolescents (F(3, 167) = 7.07, p <.001). Conclusions: Data suggest mechanisms promoting rejection‐elicited aggression may differ across development and vary for those with and without high levels of irritability. The VS‐AP is a promising tool for probing neurocognitive, developmental, and clinically relevant mechanisms underlying social rejection‐elicited aggression. [ABSTRACT FROM AUTHOR]

Introduction: There are a variety of harms associated with anabolic–androgenic steroids (AAS), with some AAS associated with an increased risk profile for users. Despite potentially different risk profiles, these harms are seldom discussed with respect to specific compounds although recent ethnographic research has identified a need to do so. Specifically, myth has developed among users with trenbolone reportedly having more dramatic effects on individuals, with reports of aggression, violent behaviour and extreme mood disturbances, and this is reflected in extant literature. This paper aims to report on the narrative surrounding the use of trenbolone among AAS users. Method: As part of a larger qualitative study, a number of AAS users were interviewed regarding their usage practices. A narrative emerged regarding the physical and psychological harms which accompanied their AAS use of which trenbolone played a central role (N = 16). Results: Of all the AAS, trenbolone was viewed as having the most deleterious consequences for those who used it. Users reported an extreme shift in risk profile for psychosocial harms, particularly increased aggression and violent behaviour, as well as impulsivity regulation issues. AAS‐using peers and family members of users reported the readily observable effect of trenbolone. Discussion and Conclusions: Users should be cognisant of the potential for significant harms and health‐care providers working with this group may consider more focused screening strategies. Future policy decisions regarding AAS may wish to consider the pivotal role trenbolone plays in adverse outcomes for this unique group of substance users. [ABSTRACT FROM AUTHOR]

Functional analyses and treatments of self‐injurious behavior and aggression have shown that such behavior is often operant. In this paper, we will revisit evidence that a subset of self‐injurious and aggressive biting may be controlled primarily by antecedent events and may have phylogenetic origins. We propose that there is a research gap of more than four decades, if one considers the wealth of basic research on biting that occurred prior to 1977. To our knowledge, that body of basic research was never fully translated or directly applied within behavior analysis. It is known that organisms (including humans) sometimes bite in the presence of aversive events (broadly defined as the presentation of aversive stimuli or the removal of reinforcers). Thus, the variables controlling biting in the context of behavioral assessment and treatment require further analysis. [ABSTRACT FROM AUTHOR]

Background: Chemical restraint (CR) (also known as rapid tranquilisation) is the forced (non‐consenting) administration of medications to manage uncontrolled aggression, anxiety, or violence in people who are likely to cause harm to themselves or others. Our population of interest was adults with mental health disorders (with/without substance abuse). There has been a growing international movement over the past 22 years towards reducing/eliminating restrictive practices such as CR. It is appropriate to summarise the research that has been published over this time, identify trends and gaps in knowledge, and highlight areas for new research to inform practice. Aims: To undertake a comprehensive systematic search to identify, and describe, the volume and nature of primary international research into CR published since 1995. Methods: This paper reports the processes and overall findings of a systematic search for all available primary research on CR published between 1 January 1996 and 31 July 2018. It describes the current evidence base by hierarchy of evidence, country (ies) producing the research, CR definitions, study purpose, and outcome measures. Results: This review identified 311 relevant primary studies (21 RCTs; 46 non‐controlled experimental or prospective observational studies; 77 cross‐sectional studies; 69 retrospective studies; 67 opinion pieces, position or policy statements; and 31 qualitative studies). The USA, UK, and Australia contributed over half the research, whilst cross‐country collaborations comprised 6% of it. The most common research settings comprised acute psychiatric wards (23.3%), general psychiatric wards (21.6%), and general hospital emergency departments (19.0%). Discussion A key lesson learnt whilst compiling this database of research into CR was to ensure that all papers described non‐consenting administration of medications to manage adults with uncontrolled aggression, anxiety, or violence. There were tensions in the literature between using effective CR without producing adverse events, and how to decide when CR was needed (compared with choosing non‐chemical intervention for behavioural emergencies), respecting patients' dignity whilst safeguarding their safety, and preserving safe workplaces for staff, and care environments for other patients. The range of outcome measures suggests opportunities to standardise future research. [ABSTRACT FROM AUTHOR]

The melatonin system and circadian disruption have well‐established links with aggressive behaviors; however, the biological underpinnings have not been thoroughly investigated. Here, we aimed at examining the current knowledge regarding the neurobiological and psychopharmacological involvement of the melatonin system in aggressive/violent behaviors. To this end, we performed a systematic review on Embase and Pubmed/MEDLINE of preclinical and clinical evidence linking the melatonin system, melatonin, and melatoninergic drugs with aggressive/violent behaviors. Two blinded raters performed an independent screening of the relevant literature. Overall, this review included 38 papers distributed between clinical and preclinical models. Eleven papers specifically addressed the existing evidence in rodent models, five in fish models, and 21 in humans. The data indicate that depending on the species, model, and timing of administration, melatonin may exert a complex influence on aggressive/violent behaviors. Particularly, the apparent contrasting findings on the link between the melatonin system and aggression/violence (with either increased, no, or decreased effect) shown in preclinical models underscore the need for further research to develop more accurate and fruitful translational models. Likewise, the significant heterogeneity found in the results of clinical studies does not allow yet to draw any firm conclusion on the efficacy of melatonin or melatonergic drugs on aggressive/violent behaviors. However, findings in children and in traits associated with aggressive/violent behavior, including irritability and anger, are emerging and deserve empirical attention given the low toxicity of melatonin and melatonergic drugs.

This article discusses a symposium on addressing stalking, which covers various topics related to psychosocial issues. The presentations at the symposium include the neurodiverse perspective of stalkers, building relationships with stalking clients, using psychological interventions to address stalking behaviors, stalking when children are involved, and promoting psychologically informed management of stalking perpetrators. The article also mentions other symposium papers that explore pathways to and from offending behavior, such as online terrorism risk in individuals with ADHD and the relationship between peer victimization and sexual offending. Another study discussed in the article examines the impact of psychological trauma, dissociation, and suggestibility on eyewitness testimony among Turkish individuals with a traumatic history. The findings suggest that trauma and dissociation can affect the accuracy of witness statements in forensic events. Lastly, the article mentions a research project that aims to explore the relationship between occupational stress, self-stigma, and attitudes toward seeking psychological help among law enforcement officers. The study will gather data from approximately 150 active-duty law enforcement officers in the United States and can provide insights for clinicians in better serving this population.

The aim of this paper is to examine parents' views and experiences regarding their adolescent children's violent and aggressive behaviours within the framework of the Non‐Violent Resistance approach in Turkish culture. The study group consisted of 40 volunteer married parents (35 females, 5 males) between the ages of 30 and 56 who resided in Central Anatolia. We conducted a descriptive study using a phenomenological design. A thematic analysis method was used in the analysis of the data. Within the framework of the results, we describe parents' experiences of their children's violence, their responses to such behaviour and their accounts of parental conflicts and presence.

Aggressive behaviors in early childhood may indicate future violence, so effective intervention measures should be taken on time to promote children's physical and psychological health. Based on sampling survey data from Jintang County in Sichuan Province of China, this paper analyzes the mechanism of rural children's aggressive behaviors from the perspective of peer influences and examines the role of parent involvement in it. The results show that the deeper the degree of deviant peer affiliation, the poorer the psychosocial adaptation of rural children, which is more likely to lead to aggressive behaviors. Parent involvement can effectively inhibit the aggressive behaviors of rural children arising from deviant peer affiliation. [ABSTRACT FROM AUTHOR]

In this paper we review the sociological literature on peer aggression among adolescents and demonstrate how it can form the basis of a new subfield in sociology on the subject of bullying. Although sociologists have mostly avoided the term bullying in classic works on adolescent aggression, these studies suggest that institutional social control, status hierarchies and social inequalities provide important social context for youth aggression. While historically they have not been in dialog with each other, when taken together sociological research on youth status relations and social networks, systemic bias, school culture and social ecology can lay the foundation of a sociology of bullying. We suggest that if sociologists see this work as shedding light on issues of bullying, they can begin to play a larger role in the shaping of the national conversation on bullying and influence anti‐bullying programs in schools to take better account of the social dimensions of bullying.

Aims: The prevalence of dementia is rising as life expectancy increases globally. Behavioural and psychological symptoms of dementia (BPSD), including agitation and aggression, are common, presenting a challenge to clinicians and caregivers. Methods: Following PRISMA guidelines, we systematically reviewed evidence for gabapentin and pregabalin against BPSD symptoms of agitation or aggression in any dementia, using six databases (Pubmed, CINHL, PsychINFO, HealthStar, Embase, and Web of Science). Complementing this formal systematic review, an illustrative case of a patient with BPSD in mixed Alzheimer's/vascular dementia, who appeared to derive benefits in terms of symptom control and functioning from the introduction of gabapentin titrated up to 3600 mg day−1 alongside other interventions, is presented. Results: Twenty‐four relevant articles were identified in the systematic review. There were no randomized trials. Fifteen papers were original case series/case reports of patients treated with these compounds, encompassing 87 patients given gabapentin and six given pregabalin. In 12 of 15 papers, drug treatment was effective in the majority of cases. The remaining nine papers were solely reviews, of which two were described as systematic but predated PRISMA guidelines. Preliminary low‐grade evidence based on case series and case reviews suggests possible benefit of gabapentin and pregabalin in patients with BPSD in Alzheimer's disease. These benefits cannot be confirmed until well‐powered randomized controlled trials are undertaken. Evidence in frontotemporal dementia is lacking. Conclusion: Gabapentin and pregabalin could be considered for BPSD when medications having stronger evidence bases (risperidone, other antipsychotics, carbamazepine and citalopram) have been ineffective or present unacceptable risks of adverse outcomes.

We are pleased to present this special issue of JCPP, which brings together a collection of cutting‐edge empirical studies that focuses on developmental trajectories and pathways associated with ADHD, conduct problems and other externalizing behaviors. JCPP has had a long‐standing focus on theoretically strong prospective longitudinal studies that elucidate behavioral change and outcomes over time, including in the areas of ADHD and externalizing disorders (Kuja‐Halkola, Lichtenstein, D'Onofrio & Larsson, 2015; Sonuga‐Barke & Halperin, 2010). Keeping with that tradition, all of the papers in this special issue employ a prospective longitudinal design and a focus on changes that unfold over development. [ABSTRACT FROM AUTHOR]

Only limited attention has been drawn to children's narrative practice of negotiating cultural ideas about who they are and what they can do. This paper focuses on children living in families where adults have psychosocial problems and analyses how they negotiate different family‐related and/or societal master narratives about their identity and agency. Twenty‐two children, 6–17 years old, have been interviewed about themselves and their lives. The findings suggest three master narratives as central in children's telling: the story of the child as problem bearer, the story of the child as inheritor of psychosocial problems and the story of the child as an unknowledgeable object. The analysis shows that children negotiate these master narratives by positioning and repositioning themselves and others in, and through, their telling. The core contribution of the study is the notion that children's problem descriptions contain important information about both material and discursive aspects of the problematic situation. Through listening to children's stories, social work practitioners and researchers can deepen their understanding of how the individual child relates to, and negotiates, wider cultural ideas about identity and agency. This knowledge is relevant in the pursuit of matching support with the child's needs and perspective. [ABSTRACT FROM AUTHOR]

Bullying is a serious concern worldwide and may compromise development for all involved. Growing evidence suggests that bullying may be viewed as a goal‐oriented strategy to achieve prestige and power or as a form of proactive aggression serving personal goals. The current paper reports a meta‐analysis of studies examining social goals‐bullying associations in youth. In addition to reporting an overall weighted‐average effect size, we compared the relative strength of associations of specific goals (status/dominance vs. antisocial/prosocial) with bullying, and examined goal type (situation‐specific vs. global), gender, and age as potential moderators. A thorough literature search identified 45 eligible effect sizes from 16 independent samples (14 sources). On average, bullying behavior was related significantly to social goal setting. Specifically, youth who displayed more bullying behavior were more likely to endorse status/power goals (r =.16, 95% CI [.11,.21]) and antisocial goals (r =.27, 95% CI [.04,.48]) and to disregard prosocial goals (r = −.10, 95% CI [−.19, −.02]) than their peers who displayed less bullying behavior. None of the included moderators related to differences in the weighted average effect size. The findings support conceptualization of bullying as instrumental behavior aimed at achieving personal goals. They also advance the understanding of motivations for bullying by indicating that, for example, goals for status/power among peers and goals of antisocial nature (e.g., revenge goals) are both related to the risk of bullying. Implications for basic research and bullying interventions are discussed. [ABSTRACT FROM AUTHOR]

Individualization and iterative design are essential components of the assessment and treatment of challenging behavior. Currently, there are few validated frameworks for engaging in iterative processes. Due to the nature of single‐case design, empirically rigorous evaluations of decision‐tree processes are particularly prohibitive. Notwithstanding, evaluations are needed. In this paper we first describe a function‐informed and mechanisms‐based (FIMB) framework for selecting treatment components employed by a university‐based practicum experience designed to expose pre‐service practitioners to a valid treatment process for challenging behavior. Then, we share a completed retrospective consecutive case series across a 6‐year period in which we conducted a technique analysis to identify which procedures were most commonly selected in the practicum, and the impact of those choices on client outcomes. The results suggest that the model can be highly effective for some, but not all, cases. Implications are discussed. [ABSTRACT FROM AUTHOR]

Nurses working in forensic psychiatric settings face unique challenges in practice, where they take on a dual role of custody and caring. Patient resistance is widespread within these restrictive settings and can take many forms. Perhaps the most disturbing form of resistance entails a patient's weaponization of their bodily fluids, with nurses as their target. The tendency in assigning motive for this act is to relegate to the psychopathology of the patient. This paper will adopt a poststructuralist perspective to reexamine this phenomenon as an act of resistance through the lens of Kristeva's concept of abjection. Patients confined in these settings have little sense of control, and in resistance may resort to the only thing available: their bodily fluids. By weaponizing the abject, patients actively violate and permeate the physical and psychological boundaries of nurses—the very boundaries considered crucial to safe and professional forensic psychiatric nursing practice. By recognizing this phenomenon as an act of resistance to confinement and loss of control, nurses may reorient their approach to care in forensic psychiatric settings. [ABSTRACT FROM AUTHOR]

This paper re‐examined the factor structure of a recently developed parent report of aggression, the Provoked and Unprovoked Aggression Questionnaire, and evaluated measurement invariance and latent mean differences across gender, age, and time. Participants were 333 mothers of toddlers (younger age group: n = 167, 53.9% boys, Mage Time 1 = 18.30 months, SD = 0.45; older age group: n = 166, 48.8% boys, Mage Time 1 = 24.29 months, SD = 0.38) who filled out provoked (eight items) and unprovoked (five items) aggression scales twice over a 3‐month period. We found evidence for the configural, metric, and scalar measurement invariance—a requirement needed to make a meaningful comparison between aggression means across gender, age groups, and time. When comparing means for boys and girls, gender differences emerged earlier for unprovoked than provoked aggression. Also, the frequency of provoked aggression increased among younger, but not older, toddlers. By developing a brief parental report of aggression in toddlerhood, we hope to fill a void of early aggression measures that tap the contextual variability in aggressive behaviors, and thereby stimulate more research to further our understanding of different types of aggression and their correlates in toddlerhood.

Previous research has confirmed that parental control is related to children's aggressive behavior. However, few studies have focused on proactive and reactive aggression to distinguish the different effects of parental psychological and behavioral control. Moreover, additional longitudinal evidence is needed to understand these links. In the current paper, a three‐wave longitudinal study was conducted to examine the developmental characteristics of proactive and reactive aggression and the role of parental control in China. A total of 484 4th‐ and 7th‐grade students participated at wave 1 (51.65% in 4th‐grade, Mage = 11.66 ± 1.52 years), 465 students (52.04% in 4th‐grade) at wave 2, and 447 children (51.90% in 4th‐grade) at wave 3. The results showed that: (1) Proactive aggression in late childhood remained stable overall, while reactive aggression displayed a clear upward trend. (2) In proactive aggression, boys and girls had a consistent developmental trend. The initial level of boys was higher than that of girls. In reactive aggression, the growth rate was inversely associated with their initial level and the initial level of boys in 7th‐grade was significantly higher than that of girls. (3) Both parental psychological and behavioral control positively predicted students' reactive aggression in 4th‐ and 7th‐grade, whereas only parental behavioral control positively predicted proactive aggression in 7th‐grade students, with no gender differences.

The paper examines how pre‐play communication between players with partial credibility affects the ensuing strategic interaction. We consider an environment where players are uncertain about the economic and psychological costs of reneging on promises but learn these at the time of their implementation. We demonstrate that in the equilibrium both players make promises. The latter are partially effective in terms of achieving collusive outcomes and improving the players' payoffs under strategic complementarity, where promises are used to signal future collusive behavior. In contrast, under strategic substitutability the ability to make a promise can be used to signal future aggressive behavior and one of the players may even get a lower expected (before the type is revealed) payoff than in the game without communication.

Background: Setting up and conducting a randomised controlled trial (RCT) has many challenges—particularly trials that include vulnerable individuals with behavioural problems or who reside in facilities that focus on care as opposed to research. These populations are underrepresented in RCTs. Approach: In our paper, we describe the challenges and practical lessons learned from two RCTs in two care settings involving long‐stay psychiatric inpatients and people with intellectual disabilities. We describe five main difficulties and how these were overcome: (1) multisite setting, (2) inclusion of vulnerable participants, (3) nutritional supplements and placebos, (4) assessment of behavioural outcomes, and (5) collecting bio samples. Conclusions: By sharing these practical experiences, we hope to inform other researchers how to optimally design their trials, while avoiding and minimising the difficulties that we encountered, and to facilitate the implementation of a trial. Both trials were registered in the Clinical Trials Register (RCT A: NCT02498106; RCT B: NCT03212092). [ABSTRACT FROM AUTHOR]

Containing aggressive behavior is an ongoing challenge in modern society. Aggressiveness is a multi‐level construct that can be driven by emotions (reactive aggression) or can be "cold‐blooded" and goal‐directed (proactive). Aggressive behavior could arise because of a misjudgment of others' intentions or can follow frontal brain lesions leading to a reduction of impulse control and emotion regulation. In the last few years, interventional and basic research studies adopting Non‐Invasive Brain Stimulation (NIBS) have significantly risen. Those techniques have been used both in healthy people, to better understand the role of certain brain regions in psychological processes, and in aggressive subjects to improve their symptoms. From an overview of the literature, focusing on the paper that uses transcranial direct current stimulation (tDCS) to reduce aggressiveness, it emerges that tDCS can (i) enhance facial emotion expression recognition, (ii) improve impulses control, and (iii) affect approach/withdrawal motivation. The current work shows the strengths and weaknesses of tDCS intervention on aggressive individuals, suggesting that this instrument could be adopted on violent people, and paves the way for intervention in some applied settings such as prison.

The Conditional Reasoning Test for Aggression (CRT‐A) indirectly measures the implicit motive to aggress by engaging respondents in inductive reasoning tasks. Most research involving the CRT‐A has been based on the original English version of the test with most data being collected in the United States. The purpose of the current paper is to evaluate the psychometric properties of a Dutch translation of this test and to examine if it could be used to predict measures of integrity. In the first of two studies, we evaluated the psychometric properties and measurement equivalence of the CRT‐A across US and Dutch samples. In the second study, we examined validity evidence for the Dutch version of the CRT‐A. Results from Study 1 indicated that the test was mostly equivalent across cultures (i.e. limited differential item functioning was detected). Results from Study 2 demonstrated that the Dutch version of the CRT‐A was correlated with measures of behavioral integrity and provided incremental prediction of integrity over and above traditional self‐report measures of explicit personality traits. We discuss the implications for using CRTs across different cultures and languages. [ABSTRACT FROM AUTHOR]

This paper critiques the Safewards model through the lens of lived experiences of psychiatric hospitalization, diagnosis of mental illness, and distress. Special focus is given to the model's tested 10 interventions and to five lesser known interventions, identifying the impact they can have on hospitalized consumers. We highlight the role and prevalence of trauma, as well as the need to prevent harm in hospital settings. We draw upon notions of hospital as a sanctuary for people and the importance of providing a safe ward. 'Sanctuary harm' and 'Sanctuary trauma' are thus defined, with emphasis placed on the Safewards interventions as means by which sanctuary can be achieved. Finally, the consumer‐perspective authors propose expansions to the model, critiquing the defining literature and moving towards a consumer experience of safety that is beyond the model's original intention: to reduce seclusion and restraint practices. Throughout the paper, the term 'consumer' is used in this context to mean people who have experienced or are experiencing psychiatric inpatient care. [ABSTRACT FROM AUTHOR]

This paper describes a Balint group in Leeds which, so far as we are aware, is unique in the UK for being aimed at higher level trainees. The paper is written from the trainee's perspective. The experience has been so useful that the group has concluded that this should be an integral part of all higher training schemes. The paper discusses two cases we brought to the group which illustrate some of the challenges faced by trainees at this level of their training. It also aims to inform the reader of the need for such an experience for higher level trainees. The cases presented were experienced by the doctors involved as troubling and disturbing to their sense of self. The Balint group provides a safe environment for discussion of the most disturbing cases, especially those which involve a hard-to-bear countertransference, and as such, fosters ongoing personal development. Standard supervisory models are considered unable to provide such a space. The Leeds group, which is made up of trainees from all specialties, have rated the Balint experience as one of the most important in their professional lives. [ABSTRACT FROM AUTHOR]

This paper focuses on the creativity of the patient in analysis and compares it to that of the artist. Taking artists' descriptions of their practices as its starting point, the paper suggests that the relationship between patient and analyst parallels that between artist and medium. Psychoanalysis and artistic process can both be seen in terms of a complex interplay between oneness and separateness in which aggression and destructiveness play an essential part. The paper includes a discussion of different forms of aggression and destructiveness within the creative process with particular reference to Winnicott's paper 'The use of an object' (1969) and Rozsika Parker's 'Killing the angel in the house' (1998). It suggests that a consideration of artists' creative processes can shed light both on the experience of the patient in analysis and on the role of the analyst in facilitating the development of the patient's creativity.

Violent ideations are increasingly recognized as an important psychological predictor for aggressive and violent behavior. However, little is known about the processes that contribute to violent ideations. This paper examines the extent to which polyvictimization triggers violent ideations in late adolescence and early adulthood, while also adjusting for dispositional and situational factors as well as prior violent ideations. Data came from three waves of the Zurich Project on the Social Development from Childhood into Adulthood (z-proso; n = 1465). Full-information maximum likelihood Tobit models were fitted to regress violent ideations experienced at ages 17 and 20 on multiple victimization experiences in the preceding 12 months while controlling for antecedent developmental risk factors and prior violent ideations. The results showed that violent ideations in late adolescence and early adulthood are influenced by violent thoughts, aggressive behavior, violent media consumption, moral neutralization of violence, and internalizing symptoms measured 2 years earlier. Experiences of polyvictimization significantly contributed to an increase in violent ideations both during late adolescence and in early adulthood. The exposure-response relationship between victimization and violent ideations did not significantly differ by sex. The findings are consistent with the notion that violent ideations are triggered by a retaliation-linked psychological mechanism that entails playing out other directed imaginary aggressive scenarios specifically in response to experiencing intentional harm-doing by others.

Background: People with an intellectual disability are more vulnerable to psychological trauma compared with the general population. The aim of this scoping review was to identify the current status of the literature on trauma that is specific to the experiences of adults with an intellectual disability, living in community settings. Methods: A scoping review was conducted using the Arksey and O'Malley (International Journal of Social Research Methodology, 2005, 8, 19) framework. Forty‐one international papers were reviewed spanning 2000–2020, and their quality assessed using the MMAT. Findings: (1) Aggressive behaviours can be symptoms of trauma, (2) there are appropriate assessment tools for the impact of trauma, (3) evidence‐based interventions for trauma may be effective, and (4) factors associated with disability can be experienced as traumatic. Conclusion: There is a growing body of literature highlighting assessment needs and potential interventions for people with an intellectual disability who have experienced psychological trauma. Further research is needed to develop trauma‐informed pathways. [ABSTRACT FROM AUTHOR]

This paper describes the development of a situation‐based tool to assess emerging adults' social competence with same‐gender friends, providing information about (1) challenges occurring in these relationships, (2) the behaviors used to manage these situations, and (3) the perceived effectiveness of these strategies. Undergraduates (N = 747; 409 women; Mage = 20.16, SD = 1.43) participated in five studies. Transgressions, conflicts of interest, and support situations emerged as key challenges, and emerging adults reported using aggressive, assertive, avoidant, and apologizing behaviors to manage these situations. In general, apologizing and assertive behaviors were judged more effective than aggressive or avoidant behaviors. Results yielded the Inventory of Friendship Challenges for Emerging Adults (IFCEA), which showed expected associations with measures of interpersonal behavior. [ABSTRACT FROM AUTHOR]

When nurses practise recovery‐focused care, they contribute positively to the consumer's mental health recovery journey and empower the person to be actively engaged in the management of their illness. While using recovery‐focused care is endorsed in mental health policy, many health professionals remain uncertain about its application with consumers who have a risk for aggression during their admission to an acute mental health inpatient setting. This paper reports on Australian research using Q‐methodology that examined the knowledge and skill components of recovery‐focused care that nurses use to reduce the risk for aggression. The data from forty mental health nurses revealed five factors that when implemented as part of routine practice improved the recovery outcomes for consumers with risk of aggression in the acute mental health settings. These factors were as follows: (I) acknowledge the consumers' experience of hospitalization; (II) reassure consumers who are going through a difficult time; (III) interact to explore the impact of the consumer's negative lived experiences; (IV) support co‐production to reduce triggers for aggression; and (V) encourage and support consumers to take ownership of their recovery journey. These findings provide nurses with a pragmatic approach to use recovery‐focused care for consumers with risk for aggression and contribute positively to the consumers' personal recovery.

One approach to manage people with behaviours of concern including agitated or aggressive behaviours in health care settings is through the use of fast‐acting medication, called chemical restraint. Such management often needs to be delivered in crisis situations to patients who are at risk of harm to themselves or others. This paper summarizes the available evidence on the effectiveness and safety of chemical restraint from 21 randomized controlled trials (RCTs) involving 3788 patients. The RCTs were of moderate to high quality and were conducted in pre‐hospital, hospital emergency department, or ward settings. Drugs used in chemical restraint included olanzapine, haloperidol, droperidol, risperidol, flunitrazepam, midazolam, promethazine, ziprasidone, sodium valproate, or lorazepam. There was limited comparability between studies in drug choice, combination, dose, method of administration (oral, intramuscular, or intravenous drip), or timing of repeat administrations. There were 31 outcome measures, which were inconsistently reported. They included subjective measures of behaviours, direct measures of treatment effect (time to calm; time to sleep), indirect measures of agitation (staff or patient injuries, duration of agitative or aggressive episodes, subsequent violent episodes), and adverse events. The most common were time to calm and adverse events. There was little clarity about the superiority of any chemical method of managing behaviours of concern exhibited by patients in Emergency Departments or acute mental health settings. Not only is more targeted research essential, but best practice recommendations for such situations requires integrating expert input into the current evidence base. [ABSTRACT FROM AUTHOR]

This is my critical commentary on Michael Shermer's paper 'Morality is real, objective, and natural.' Shermer and I agree that morality is both real and objective. Here I raise serious reservations about both Shermer's account of where morality comes from and his account of what morality tells us to do. His approach to the foundations of morality would allow some very disturbing behaviors to count as moral, and his approach to what morality says does not provide the action guidance we need from a moral theory.

This paper analyzes a model wherein firms' owners hire biased managers in a differentiated goods duopoly with network effects. We show that whether firms hire an aggressive manager or not depends on both the degree of product differentiation and the strength of network effects in price competition whereas it does not depend on the degree of product differentiation or the strength of network effects in quantity competition. Thus, the attitudes of firms' managers depend on the type of competition and the relative magnitude of the strength of network effects to the degree of product differentiation.

Aim: Provide insight into the concept of stress in the context of challenging behaviour of nursing home residents with dementia and its causes and consequences. Background: Challenging behaviour is frequent in residents with dementia, but consequences for nursing staff are unclear. Introduction: Challenging behaviour of residents can be enervating for nurses and may lead to stress. Although stress in general is associated with negative outcomes, an overview of stress in this context would be a welcome addition to the field. Method: Concept analysis according to Walker and Avant. Results: Identified antecedents of stress: physical and verbal aggression, conflicts, excessive demands and being unresponsive (residents), age, experience, tenure, nursing level and training (nursing staff). Defining attributes: disturbed homoeostasis and the personal appraisal of the situation. Identified consequences regard health, psychological aspects and behaviour. Discussion: Intervening in the identified factors may contribute to prevention of stress in nursing staff. Limitations: Given a lack of strong empirical studies, our analysis is not based on a high level of evidence and needs to be tested. Papers from before 1990 might have been missed. Conclusion: The concept analysis revealed that nursing staff stress in the context of challenging behaviour may result from resident and nursing staff factors. Besides health and psychological consequences, behavioural consequences can enormously impact the well ‐ being of residents. Implications: Application in daily care to support teams in influencing resident and nursing staff factors could prevent stress, for instance using behavioural management training or recruiting higher educated nursing staff. Given the increasing complexity of care, creating specialized units with specifically trained staff for different groups of people with dementia may be desirable. [ABSTRACT FROM AUTHOR]

Generally speaking, just war theory (JWT) holds that there are two just causes for war: self‐defence and 'other‐defence'. The most common type of the latter is popularly known as 'humanitarian intervention'. There is debate, however, as to whether these can serve as just causes for preventive war. Those who subscribe to JWT tend to be unified in treating so‐called preventive war with a high degree of suspicion on the grounds that it fails to satisfy conventional criteria for jus ad bello; – particularly the just cause and last resort criteria. Francisco di Vitoria held that the only just cause for war was 'a wrong received', which renders impossible any justification for preventive war. There are assumptions implicit in recent military practice, however – most notably, the US‐led invasion of Iraq in 2003 – that challenge this ban on preventive war. Interestingly, both supporters and critics attempt to justify their views through the broader logic of JWT; viz., through a conception of what is good for both political communities and individuals, and through a legitimate defence of these goods. Supporters point to situations where so‐called rogue states represent 'grave and imminent risk' of committing acts of aggression as grounds that justify preventive war; critics argue that to attack another political community on the basis of crimes not yet committed is a breach of the very rights JWT was created to defend. The advocate of preventive war does not appreciate important aspects concerning the morality of war. In the ongoing tension between Iran and The United States and her allies – if the rhetoric is to be believed – I am asked to tolerate a threat to my security and liberty, and to risk suffering aggression in defence of the rights of the antagonistic, but not yet aggressive, state. The crucial question is how such tolerance and risk fit in with the logic of just war: at what point, if any, does the risk of being attacked become great enough to justify declaring war in anticipation? In this paper I highlight some of the theoretical and practical difficulties in determining what counts as a grave and imminent threat, focusing especially on the complicated case of 'imminence' in the face of so‐called 'Weapons of Mass Destruction'. Secondly, I will argue that not only is the notion of preventive war inconsistent with the defence of the rights of political communities that JWT requires; it is also forbidden by the proportionality requirement of jus ad bellum. A risk of being subjected to aggression is the price for global peace. Whilst political communities can do much to prevent aggression and prepare themselves in case it occurs, the conditions for just war require that this prevention and preparation stop short of declaring war. We must live with a certain degree of risk in this area. [ABSTRACT FROM AUTHOR]

BACKGROUND: Bullying behavior is a concern among school‐aged youth and anti‐bullying programs have been implemented in schools throughout North America. Most anti‐bullying programs are delivered to adolescent youth because antisocial‐aggressive behaviors are typically associated with this developmental stage. This paper is a review of empirically evaluated school‐based bullying prevention and intervention programs in North American elementary schools. METHODS: We conducted a systematic, critical review of bullying prevention programming. Data were analyzed to determine the study method, intervention components, measurement of bullying, aggression, or peer victimization, outcomes measured, and results. RESULTS: Our review resulted in the identification of 10 interventions aimed at youth in grades K‐6 enrolled in North American elementary schools. Effective intervention strategies targeted a variety of bullying behaviors using diverse mechanisms and included a school—and community‐wide approach. Direct outcomes of the reviewed evaluations were centered on bullying, aggression, and victimization. Indirect outcomes of review evaluations included strategies for bystanders, school achievement, perceived school safety, and knowledge or attitudes about bullying. CONCLUSIONS: Recommendations for promising practices in effective bullying intervention programming are offered. The review concludes with suggestions for supporting school health staff and in‐service teachers drawn from the body of research, and offers direction for future study. [ABSTRACT FROM AUTHOR]

People brought in by police (BIBP) to the ED are a potentially vulnerable group. This narrative scoping review aimed to identify, evaluate and summarise current literature regarding the frequency of presentation, demographic and clinical profile of patients (including reason for presentation), care delivery, and outcomes for people BIBP to the ED, and identify current gaps in knowledge. The review involved searching EMBASE, CINAHL and PubMed using a combination of terms: emergency/ED coupled with police custody/watch house or police presentation, for papers published in English language from January 2006 to November 2017. A total of 20 studies met the inclusion criteria. These included 17 observational (non‐randomised controlled trials) quantitative studies and three descriptive case reports. The proportion of presentations to ED that were BIBP varied depending on the study design and sampling frame. People BIBP often presented with mental health problems, substance use problems, aggressive behaviour and injury caused by self or others. Of studies focused specifically on patients arriving to the ED in mental health crisis (i.e. suicidal ideation or self‐harm), 18–27% were BIBP. ED presentations BIBP were mostly male and typically younger than people arriving by other means. The nature of care provided in the ED and outcomes of the acute episode of care were typically not well described. Limited research regarding people BIBP to the ED limits the ability to comprehensively understand their demographic and clinical profile and outcomes of emergency care. Further research is required to inform if and where in the patient's journey further improvements may be targeted. [ABSTRACT FROM AUTHOR]

Pervasive physical conflict generates negative outcomes. This paper (a) thoroughly describes the problem of early aggression, (b) identifies emotion regulation (ER) and social information processing (SIP) skills as targets for aggression prevention, and (c) locates skills training within a new conceptual framework. According to this framework, prevention programs should teach ER and SIP skills early and should target contextual factors. Multiple professions are well positioned to intervene using existing tools. Aggression prevention research should consider both emotion and cognition, improve measurement and study design, and incorporate theories that address skill development as well as the social justice implications of aggression prevention.

This paper describes the process of couple therapy with two couples that used blame as the currency of exchange in their relationship. Both couples struggled with managing three‐person relationships. The triangular setting of couple psychotherapy provoked and triggered primitive anxieties around exclusion, rejection and abandonment in both cases. I draw upon clinical work with two such couples to illustrate how one repeatedly collapsed the triangular space whereas the other gradually became more able to bear it. I refer to scientific evidence of the brain's ability to continue to change in response to new learning by forming fresh neural connections throughout life. I suggest that the repetitive occurrence of new experiences within couple psychotherapy can generate new neural pathways thereby biologically influencing new ways of how partners might respond to each other. I conclude by highlighting the therapeutic potential of the framework within which couple psychotherapy takes place, a triangular configuration which offers a developmental opportunity for navigating primitive anxieties related to triangular relationships.

This is a protocol for a Campbell systematic review of intervention effectiveness. The goal of this systematic review is to answer the following questions based on the available empirical evidence: Are there nutritional interventions (dietary manipulation, fortification or supplementation) that can reduce excessive aggression towards others in children/youth? If yes, how strong is their effect and is there a difference among the three intervention types? Are there nutritional interventions that can reduce antisocial behaviors in children/youth? If yes, how strong is their effect and is there a difference among the intervention types? Are there nutritional interventions that can reduce violent offending in children/youth? If yes, how strong is their effect and is there a difference among the intervention types? Are there nutritional interventions that can reduce non‐violent offending in children/youth? If yes, how strong is their effect and is there a difference among the intervention types? What implementation barriers and solutions to these exist in relation to the above nutritional interventions in children/youth? [ABSTRACT FROM AUTHOR]

Internet users' activities are critical to the development and success of Web 2.0 systems, such as online communities. Within the community's participation, knowledge sharing, and communications, users may conduct aggressive behaviors that would have a negative impact on that online community. This study investigates factors that affect Chinese users' aggression intention in online communities. Research findings show that online aggression can be inhibited by internal deterrents of face saving and moral beliefs, which may be enhanced through implementation of consequences from an effective community policy and peer pressure among community members. Differences in the effects of the deterrence measures exist between younger and older users. This paper contributes theoretically and empirically to Web 2.0 research and has practical implications for virtual community management. [ABSTRACT FROM AUTHOR]
