Psychopathy is found in incarcerated populations and in the general population, among men and women. This study investigated if there were any gender differences between men and women with heightened levels of psychopathic traits regarding psychopathy factor scores, criminality, aggression and victimization. A randomized sample of 2500 mixed-sex (52.6 % women) participants (M=22.15; SD=1.38) from the general population, aged 20-24, was used. Results showed that women with psychopathic personality traits had significantly higher behavioral tendencies (e.g., impulsivity) on psychopathy than men with psychopathic personality traits. Men scored higher on violent criminal offences and criminal versatility and men and women differed in aggressive behavior and victimization. Gender differences in psychopathy features may create different needs for treatment. / Personer med psykopati finns både bland kliniska populationer och bland normalpopulationen, bland män och kvinnor. Den här studien undersökte om det fanns könsskillnader mellan män och kvinnor med förhöjda nivåer av psykopatiska drag när det gäller psykopatifaktorer, kriminalitet, aggression och utsatthet. Ett slumpmässigt urval från normalpopulationen med både män och kvinnor (52,6 %), ålder 20-24 år (M=22,15; SD=1,38), användes. Resultaten visade att kvinnor med psykopatiska egenskaper har signifikant högre beteendemässiga drag av psykopati än män med psykopatiska egenskaper. Män uppvisade högre nivåer av våldsam kriminalitet och mångfald i brott. Män och kvinnor med psykopatisk personlighet uppvisade olika aggressiva beteenden och rapporterade olika typer av utsatthet. Könsskillnader i psykopatiska egenskaper kan skapa olika behov av behandling.

Syftet med den här studien är att, genom att kontrollera sambandet mellan ungdomars Internetanvändning och deras åsikter kring hur ungdomar bör uttrycka sig på Internet, undersöka vilken typ av Internetanvändare som är mer eller mindre sannolik att acceptera, utföra eller utsättas för aggressiva/provocerande beteenden på Internet. Studien utfördes genom en kvantitativ enkätundersökning där 139 gymnasieelever från en medelstor stad i Hallands län fick svara på frågor om deras Internetvanor och deras åsikter kring beteenden på Internet. Därefter utfördes olika statistiska test i SPSS för att undersöka sambandet mellan deltagarnas Internetanvändning och deras åsikter om beteenden på Internet. Studien kom fram till att det finns ett samband mellan ungdomars aggressiva/provocerande beteenden på Internet och hur ungdomar använder Internet. Studien visar även ett samband mellan ungdomars utsatthet for aggressiva/provocerande beteenden och hur de använder Internet. Dessutom visar studien att ungdomar uppfattar sig själva generellt som bättre uppträdande än andra ungdomar, men anser varken att andra ungdomar uttrycker sig aggressivt/provocerande eller särskilt välbemötande. / The purpose of this study is the investigate adolescents’ opinions concerning online behaviors to find out whether they accept, use or are victims of aggressive/provocative behaviors online. By investigating the connection between adolescents’ use of Internet and their opinions of how other adolescents should behave online the study aims to find out which type of user is more likely to engage in aggressive/provocative behaviors online. A quantitative survey was carried out on 139 upper secondary school students at a school in an average sized city in Halland’s county. The participants answered questions concerning their online habits and their opinions about online behavior. To analyze the results the computer program SPSS was used in order to investigate the connection between the participants’ online habits and their opinions about online behavior. The study concluded that there is a connection between upper secondary students’ aggressive/provocative behaviors online and their online habits. The study also shows that there is a connection between adolescent’s exposure to these kinds of behaviors and their Internet habits. Finally, the study shows that adolescents’ interpret themselves as less aggressive/provocative than their peers, although they interpret other adolescents’ as neither aggressive/provocative nor particularly polite.

BAKGRUND: Studierna visar att våldet har ökat med åren. Riskfaktorer och riskbeteenden har identifierats och orsakerna kan vara flera till att patienten upplever ohälsa. Forskningen inom detta fält har hittills fokuserat på bakomliggande orsaker till patientens aggressiva beteende och bedrivits under många år. Ökade kunskaper om sjuksköterskans upplevelse av att vårda patienter med aggressivt beteende inom psykiatrisk vård kan bidra till att utveckla omvårdnad anpassad till situationen, i syfte att främja hälsa. SYFTE: Studiens syfte är att utforska sjuksköterskans omvårdnad och upplevelse av att vårda patienter med aggressivt beteende inom psykiatrisk vård. METOD: Litteraturstudie av kvalitativa och kvantitativa studier. RESULTAT: Analysen resulterade i tre huvudkategorier och 12 underkategorier. Huvudteman som uppkom var; sjuksköterskan i interaktion med patienten, organisatoriska faktorer och personliga faktorer samt underkategorier som handlade om; avledning av hotfulla situationer, personligt utrymme, information och bedömning, gränssättning, riskfaktorer kopplade till aggression, bristande support från chefer, bemanning, personalsäkerhet, erfarenhet och kommunikationsfärdigheter, lojalitet gentemot patienten och arbetet, hopplöshet och besvikelse samt coping. SLUTSATS: Resultatet visar att sjuksköterskor upplever vårdandet av patienter med aggressivt beteende inom psykiatrisk vård på olika sätt. Sjuksköterskans upplevelse kan komma att inverka på patientens omvårdnad. För att sjuksköterskan ska kunna arbeta hälsofrämjande behövs verktyg och färdigheter för att kunna hantera aggressionen på ett adekvat sätt. Ökad kompetens upplevs ha en inverkan på vårdkvalitén för patienten och upplevs påverka antalet våldsincidenter. En stödjande ledningsstruktur och god arbetsmiljö upplevs som viktig och kan tänkas bidra till att allt fler sjuksköterskor stannar kvar på sin arbetsplats inom den psykiatriska vården. / BACKGROUND: The studies show that violence has increased over the years. Risk factors and risk behaviors have been identified and the reason for the patient to experience illness can be many. Research in this field has so far focused on the underlying causes of the patient's aggressive behavior and has been conducted for many years. Increased knowledge of the nursing experience of caring for patients with aggressive behavior in psychiatric care can help to develop nursing care adapted to the situation, in order to promote health. AIM: The aim of the study was to explore nursing care and nurse’s perceptions of caring for patients with aggressive behavior in psychiatric care. METHOD: The systematic review was based on both qualitative and quantitative studies. RESULTS: The analysis resulted in three main categories and 12 subcategories. The main themes that emerged were: the nurse in the interaction with the patient, organizational and personal factors as well as subcategories that dealt; diversion of threatening situations, personal space, information and assessment, setting limits, risk factors associated with aggression, lack of support from managers, staffing, personnel security, experience, and communication skills, loyalty towards patient and work, hopelessness and disappointment and coping. CONCLUSION: The results show that nurses experience the care of patients with aggressive behavior in psychiatric care in different ways. The nurse's experience may affect the patient's health. For the nurse to work with health promotion it is required tools and skills to handle aggression in an adequate way. Increased skills are perceived to have an impact on the quality of care for the patient and are experienced to affect the number of violent incidents. A supportive management structure and good working environment is perceived to be important and could contribute to more and more nurses to remain in their workplace in psychiatric care.

The peer group is a dynamic context within which children and adolescents have a wide range of experiences, both positive and negative. Friendships provide support and a sense of belonging; however, friendships can also be contexts within which competition and aggression occur. During childhood and adolescence, aggression and victimization are likely to occur in the school context and in situations where several members of the peer group are present and sometimes actively (or passively) participating. In the seminal work related to bullying as a group process, Salmivalli and colleagues identified distinct roles that children take when enacting aggression (Salmivalli et al., 1996). Salmivalli's work, in the area of participant roles, however, has focused on overt bullying, a specific subtype of aggression which has a specific meaning within the peer relations literature. To date, the participant roles have not been measured within the context of overt and relational aggression. The purpose of the present study is to examine the psychometric properties of the Overt Aggression Participant Role Scale (OAPRS) and the Relational Aggression Participant Role Scale (RAPRS), two new scales designed by the author, to measure the aggressor, assistant, reinforcer, defender, outsider, and victim roles during acts aggression, as opposed to bullying. Additional goals include: 1) exploring the associations among the roles, 2) examining measurement equivalence across gender and grade level, and 3) exploring associations of the participant roles with measures of sociometric status and depressive symptoms. Findings point toward the psychometric properties of the two scales being quite robust. The data fit the 12 factor model and the scales measure the constructs equivalently across gender and three grade groups. The aggressor, assistant, and reinforcer roles were strongly associated as were the aggressor and victim roles. Several relational roles were highly overlapping, suggesting reciprocity of roles. Few meaningful gender or grade level differences were found resulting in more similarity in the overt and relational roles than differences. The outsider role was the only role not associated with depressive symptoms. Implications for prevention and intervention are discussed.

Bullying is a pervasive problem in schools, but more recent attention has been given to bullying that takes place via electronic media. To study electronic bullying and aggression effectively research needs to consider the unique qualities of the electronic medium including its capacity for anonymity, disinhibition, public forum, and under-regulated content. Electronic bullying does not occur in isolation; therefore it must be studied in relation to peer processes that occur in the “real world.” Research has neither uncovered the potential “real world” precursors of electronic bullying and aggression nor has it uncovered how students perceive the harmfulness of electronic aggression. The two studies presented here fill these gaps in the literature. The first study examined the precursors of electronic bullying and victimization in a sample of grade 9 and 10 students who were followed longitudinally. Students were administered questionnaires assessing electronic bullying/victimization, perceived harm of electronic aggression, empathy, normative beliefs, and prosocial behavior. The results indicated that “real world” behaviors such as verbal bullying and prosocial behavior were precursors of electronic bullying, while victimization by social bullying and social aggression were precursors for electronic victimization. In addition, females, older students, and students with less prosocial behavior were at risk for involvement in electronic bullying. Implications for these findings include the importance of integrating interventions that foster positive behavior in the “real world” and online, particularly for students at highest risk for involvement. The second study examined students’ harm perceptions of electronic aggression and how similar behavioral and cognitive factors may also influence perceptions of electronic aggression. Cross-sectional data were collected from students in grades 7 through 9 who were administered the same questionnaires above. Electronic bullying was perceived as more harmful than physical and social aggression, particularly for girls and students with highly prosocial behavior. Thus, electronic aggression is a very serious issue for students and education is needed to change the social norms for acceptable behavior in cyberspace. Consistent with social-cognitive theory, similar demographics and behaviors predicted electronic behavior and perceptions. Future research should continue to extend the social-cognitive model to electronic conflict. / Thesis (Master, Psychology) -- Queen's University, 2009-09-22 21:15:56.732

There continues to be doubt regarding the validity of laboratory aggression paradigms. This paper provides an investigation of the construct validity of one prominent aggression task, the Taylor Aggression Paradigm (TAP), within a Multitrait Multimethod Matrix (MTMM) methodology. Participants consisted of 151 male undergraduate psychology students with a median age of 19 years old (M=19.45, SD = 2.03). Participants completed self-report and behavioral measures of aggression, impulsivity, and pro-social behavior which were analyzed using a Correlated Trait – Correlated Method Confirmatory Factor Analysis model. Results supported the construct validity of the MTMM model and the TAP. This study provides one of the only a priori tests of construct validity for the TAP and provides a basis for additional validation studies using this methodology.

NutzerInnen von gewalthaltigen Medien geben einerseits oftmals zu, dass sie fiktionale, gewalthaltige Medien konsumieren, behaupten jedoch gleichzeitig, dass dies nicht ihr Verhalten außerhalb des Medienkontexts beeinflusst. Sie argumentieren, dass sie leicht zwischen Dingen, die im fiktionalen Kontext und Dingen, die in der Realität gelernt wurden, unterscheiden können. Im Kontrast zu diesen Aussagen zeigen Metanalysen Effektstärken im mittleren Bereich für den Zusammenhang zwischen Gewaltmedienkonsum und aggressivem Verhalten. Diese Ergebnisse können nur erklärt werden, wenn MediennutzerInnen gewalthaltige Lernerfahrungen auch außerhalb des Medienkontexts anwenden. Ein Prozess, der Lernerfahrungen innerhalb des Medienkontexts mit dem Verhalten in der realen Welt verknüpft, ist Desensibilisierung, die oftmals eine Reduktion des negativen Affektes gegenüber Gewalt definiert ist. Zur Untersuchung des Desensibilisierungsprozesses wurden vier Experimente durchgeführt. Die erste in dieser Arbeit untersuchte Hypothese war, dass je häufiger Personen Gewaltmedien konsumieren, desto weniger negativen Affekt zeigen sie gegenüber Bildern mit realer Gewalt. Jedoch wurde angenommen, dass diese Bewertung auf Darstellungen von realer Gewalt beschränkt ist und nicht bei Bildern ohne Gewaltbezug, die einen negativen Affekt auslösen, zu finden ist. Die zweite Hypothese bezog sich auf den Affekt während des Konsums von Mediengewalt. Hier wurde angenommen, dass besonders Personen, die Freude an Gewalt in den Medien empfinden weniger negativen Affekt gegenüber realen Gewaltdarstellungen zeigen. Die letzte Hypothese beschäftigte sich mit kognitiver Desensibilisierung und sagte vorher, dass Gewaltmedienkonsum zu einem Transfer von Reaktionen, die normalerweise gegenüber gewalthaltigen Reizen gezeigt werden, auf ursprünglich neutrale Reize führt. Das erste Experiment (N = 57) untersuchte, ob die habituelle Nutzung von gewalthaltigen Medien den selbstberichteten Affekt (Valenz und Aktivierung) gegenüber Darstellungen von realer Gewalt und nichtgewalthaltigen Darstellungen, die negativen Affekt auslösen, vorhersagt. Die habituelle Nutzung von gewalthaltigen Medien sagte weniger negative Valenz und weniger allgemeine Aktivierung gegenüber gewalthalten und nichtgewalthaltigen Bildern vorher. Das zweite Experiment (N = 103) untersuchte auch die Beziehung zwischen habituellem Gewaltmedienkonsum und den affektiven Reaktionen gegenüber Bildern realer Gewalt und negativen affektauslösenden Bildern. Als weiterer Prädiktor wurde der Affekt beim Betrachten von gewalthaltigen Medien hinzugefügt. Der Affekt gegenüber den Bildern wurde zusätzlich durch psychophysiologische Maße (Valenz: C: Supercilii; Aktivierung: Hautleitreaktion) erhoben. Wie zuvor sagte habitueller Gewaltmedienkonsum weniger selbstberichte Erregung und weniger negative Valenz für die gewalthaltigen und die negativen, gewalthaltfreien Bilder vorher. Die physiologischen Maßen replizierten dieses Ergebnis. Jedoch zeigte sich ein anderes Muster für den Affekt beim Konsum von Gewalt in den Medien. Personen, die Gewalt in den Medien stärker erfreut, zeigen eine Reduktion der Responsivität gegenüber Gewalt auf allen vier Maßen. Weiterhin war bei drei dieser vier Maße (selbstberichte Valenz, Aktivität des C. Supercilii und Hautleitreaktion) dieser Zusammenhang auf die gewalthaltigen Bilder beschränkt, mit keinem oder nur einem kleinen Effekt auf die negativen, aber nichtgewalthaltigen Bilder. Das dritte Experiment (N = 73) untersuchte den Affekt während die Teilnehmer ein Computerspiel spielten. Das Spiel wurde eigens für dieses Experiment programmiert, sodass einzelne Handlungen im Spiel mit der Aktivität des C. Supercilii, dem Indikator für negativen Affekt, in Bezug gesetzt werden konnten. Die Analyse des C. Supercilii zeigte, dass wiederholtes Durchführen von aggressiven Spielzügen zu einem Rückgang von negativen Affekt führte, der die aggressiven Spielhandlungen begleitete. Der negative Affekt während gewalthaltiger Spielzüge wiederum sagte die affektive Reaktion gegenüber Darstellungen von gewalthaltigen Bildern vorher, nicht jedoch gegenüber den negativen Bildern. Das vierte Experiment (N = 77) untersuchte kognitive Desensibilisierung, die die Entwicklung von Verknüpfungen zwischen neutralen und aggressiven Kognitionen beinhaltete. Die Teilnehmer spielten einen Ego-Shooter entweder auf einem Schiff- oder einem Stadtlevel. Die Beziehung zwischen den neutralen Konstrukten (Schiff/Stadt) und den aggressiven Kognitionen wurde mit einer lexikalischen Entscheidungsaufgabe gemessen. Das Spielen im Schiff-/Stadt-Level führte zu einer kürzen Reaktionszeit für aggressive Wörter, wenn sie einem Schiff- bzw. Stadtprime folgten. Dies zeigte, dass die im Spiel enthaltenen neutralen Konzepte mit aggressiven Knoten verknüpft werden. Die Ergebnisse dieser vier Experimente wurden diskutiert im Rahmen eines lerntheoretischen Ansatzes um Desensibilisierung zu konzeptualisieren. / Users of violent media often state that they consume fictional violent media and claim that this does not influence their behavior outside of the media context. Media users reason that they can easily distinguish between things learned in a fictional context and things learned in reality. In contrast to these claims, meta-analyses report medium-sized effects between media violence consumption and aggressive behavior. These effects can only be explained if media users also apply learning experiences from the media outside the media context. One of the processes linking learning experiences in the media context to behavior in the real word is desensitization, which is often defined as a reduction of negative affect towards violence. To investigate the process of desensitization, four experiments were conducted. The first hypothesis investigated in these experiments was that persons who have a higher level of violent media exposure show less negative affect towards depictions of real violence compared to persons with a lower level. However, it was assumed that this reduction in reaction would be limited to depictions of real violence and would not be found in response to depictions of nonviolent pictures electing negative affect. The second hypothesis referred to the role of affect experienced during exposure to media depictions of violence, assuming that especially people who enjoy the violence while consuming the media show less negative affect towards depictions of real violence. The final hypothesis addressed cognitive desensitization effects and predicted that media violence use leads to transfer effects from responses to violent cues to initially neutral stimuli The first experiment (N = 57) examined to what extent the habitual use of media violence predicts the self-reported affect (Valence and Arousal) towards depictions of real violence and nonviolent pictures eliciting negative affect. Habitual media violence exposure predicted less negative valence and less arousal toward violent pictures and negative nonviolent pictures. The second experiment (N = 103) also examined the relationship between habitual media violence exposure and the affective reactions towards images of real violence as well as negative, nonviolent scenes. Additionally, affect while watching violent media was added as a second predictor. The affect toward the images was also obtained by psychophysical measures (Valence: activity of C. Supercilii; Activation: skin conductance). As in experiment 1, habitual media violence exposure predicted less self-reported negative valence and less self-reported arousal for the violent pictures and the negative nonviolent pictures. The physiological measures replicated this result. However, a different pattern emerged for the enjoyment of violent media. People who enjoyed violent media more showed a reduction of affective responsivity toward violence on all four different measures. Additionally, for three of the four measures (skin conductance, self-reported negative valence and the activity on the C. Supercilii) this relationship was limited to the violent pictures, with no or little effect on the negative, but nonviolent pictures. A third experiment (N = 73) studied affect while participants played a violent computer game. A game was specially programmed in which specific actions could be linked to the activity of the C. Supercilii, an indicator for negative affect. The analysis of the C. Supercilii showed that repeatedly performing aggressive actions during the game led to a decline in negative affect accompanying the aggressive actions. The negative affect during aggressive actions in turn predicted less negative affective responses to violent images of real-life violence but not to nonviolent, negative images. The fourth experiment (N=77) showed cognitive desensitization effects, which involved the formation of links between neutral and aggressive cognitions. Participants played a first-person shooter game either on a ship or a city level. The relationship between neutral constructs (ship/city) and aggressive cognitions was measured using a lexical decision task. Playing the game in a ship/city level led to shorter reaction time for aggressive words following ship/city primes respectively. This indicated that the neutral concepts introduced in the game had become associated with aggressive cognitions. The findings of these four experiments are discussed in terms of a learning theory approach to conceptualizing desensitization.

Syfte: Syftet med studien var att belysa olika omvårdnadsåtgärder som bidrar till att minska beteendemässiga och psykiska symtom vid demens (BPSD). Metod: Examensarbetet har utförts som en litteraturstudie med 15 vetenskapliga artiklar varav fem kvantitativa och tio kvalitativa. Datainsamling har genomförts i de vårdvetenskapliga databaserna CINAHL och PubMed. Resultat: De olika omvårdnadsåtgärderna som bidrog till att minska BPSD var att anpassa vårdmiljön genom färgsättning och möjlighet till enkelrum samt egen toalett, även att använda sig av personcentrerad och behovsanpassad vård för att beakta hela människan och dess behov, att stimulera hörsel, lukt och känsel med hjälp av taktil och fotmassage, aromaterapi, akupressur och musik. Samt att använda sig av montessori baserade aktiviteter som innebar att personer fick ägna sig åt intressen som de haft innan sjukdomen uppkom och teoretiskt baserade aktiviteter såsom att läsa tidning och lösa korsord. Dessa omvårdnadsåtgärder bidrog till att minska symtom vid BPSD såsom agitation, aggression samt verbal aggression. Konklusion: Genom att anpassa vårdmiljön med hjälp av design och anpassning, att använda sig av personcentrerad och behovsanpassad vård, att stimulera hörsel, lukt och känsel som taktil och fotmassage, aromaterapi, akupressur och musik. Samt att använda sig av montessori baserade aktiviteter och teoretiskt baserade aktiviteter minskas BPSD samtidigt som möjligheten till en god omvårdnad förbättras och livskvaliteten hos personer med demenssjukdom kan öka.

The aim of this study was to investigate the causes and consequences of learner aggression in rural secondary schools in the Empangeni District of KwaZulu-Natal. The study also sought to establish the management strategies required to manage learner aggression in rural secondary schools. An in-depth literature study was conducted in this regard. A qualitative research design and methodology was adopted to investigate the phenomenon through an interview process with participants from five rural secondary schools. This study found that the causes of learner aggression were rooted in the family, the environment and the school. It was further established that the consequences of learner aggression were so serious that it resulted in victims experiencing intense fear, anxiety, tension, depression and ill-health. Furthermore, the findings of the empirical investigation concurred, to a large extent, with the findings of the literature study. Based on these findings, recommendations were made regarding the management of learner aggression in rural secondary schools. / Educational Leadership and Management / M. Ed. (Education Management)
