Previous research supports the idea that individuals high in trait anger tend to experience more hostile attribution bias. According to the Integrative Cognitive Model, cognitive factors, such as rumination, may increase the risk of hostile attribution bias and any subsequent aggressive behaviors. Sex differences are apparent in rumination and anger expression. The present research explored the potential role trait rumination plays in hostile attribution bias as well as potential conditional effects of sex on this relationship. Participants were asked to complete a number of self-report measures and vignettes of ambiguously hostile situations adapted to improve reliability. Hypotheses were largely supported and trait anger rumination was significantly predictive of hostile attribution bias; however, conditional effects of sex were non-significant. The adapted hostile attribution bias measure had improved reliability and may have utility for a survey-based method to assessing hostile attribution bias. Findings may further our understanding of hostile interpretations and potential for subsequent aggressive behaviors in high trait ruminators in ambiguous situations as well as lead to potential areas of intervention to reduce anger and anger rumination.

For a while, video games have been the target of scrutiny with regards to their perceived potential to adversely affect younger individuals. In particular, it is often argued that these video games, particularly those of violent nature, may increase hostility to an extent that it manifests itself in violent behavior. This thesis aims to denote what effects these video games have on young adults, particularly in relation to the respondents’ indicated extent of adverse childhood experiences, trait anger, and competitiveness, all three of which were assumed to have a positive relationship with hostility. A survey was distributed to students attending Western Kentucky University in an attempt to measure what effects these three aforementioned variables have on young adults, in addition to what affects video game playing and violence in video games may have on hostility and aggression. From the data acquired, it was clear that while adverse childhood experiences had no statistical significance in this study and higher competitiveness indicated a very slight decline in hostility, trait anger did in fact appear to raise hostility in the respondents. Additionally, increases in exposure to both video game play and violence in video games were shown to lead to a decrease in hostility. From this, it would appear that trait anger was the only variable to truly increase hostility in young adults, and the often-discussed variables of video game play and violence in video games both appear to decrease hostility in respondents as exposure to either factor increases, thus going against the common assumptions.

Ongoing investigations of drunken aggression tend to focus on 1) situational cues, and 2) individual variables such as personality traits. This study investigated the hypothesis that an undergraduates attention would be pulled toward a nonconscious presentation of aggression stimuli, especially in the presence of alcohol cues, and especially if he or she was high on trait anger [as measured using the State Trait Anger Expression Inventory (STAXI); Spielberger, 1988] and had high expectancies for behaving aggressively while drinking alcohol [as measured using the Expectancy Questionnaire for Alcohol and Aggression Lo Dose (EQAAL); Epps, Hunter, LeVasseur, Steinberg, and Hancock, unpublished manuscript]. Seventy-nine of the participants who completed questionnaires also completed one of the two computer tasks (adapted from John Bargh and associates) weeks later in either the Barroom or the Cleanroom. Attention to HiAggression words (as measured by reaction time or error rate difference scores) was significantly higher than attention to NonAggression words using the parafoveal visual task, with observed power at 1. No significant differences were found using the dichotic listening task. Additionally, there was a significant three-way interaction (Word Type X Setting X Angry Temperament) when participants where blocked according to high vs. low angry temperament scores. Follow-up analyses as well as regression analyses for the specific hypothesis provided mixed results. Individuals lower on angry temperament tended to demonstrate higher levels of attentional interference for aggression words, but only in the presence of alcohol cues. Conversely, individuals higher on angry temperament evidenced higher levels of attentional interference, but only in the absence of alcohol cues. It appears that the relationships among these variables are by no means straightforward. Studies that include an opportunity to aggress behaviorally may shed more light on whether ones level of attentional interference and self-reported personality traits can be combined to predict aggression in the presence of alcohol cues. The parafoveal visual task is recommended as the methodology of choice for these future studies.

The purpose of this study was to investigate the influence of hostile attribution style (HAS) on the processes linking job stressors and CWB. Self and peer data were collected via online questionnaires from employed participants recruited from undergraduate classes and non-student employees. Using data from 147 dyads of employees and coworkers, the effects of HAS on three areas were examined: the influence of HAS on the appraisal of psychosocial (incivility, interactional justice, and interpersonal conflict) and nonsocial (organizational constraints and workload) stressors; HAS as a moderator of the link between stressors and CWB; and HAS as mediator of the link between CWB and the individual difference variables of negative affectivity (NA), trait anger, and Machiavellianism. Regarding appraisals, HAS was more strongly related to psychosocial stressors than to workload (nonsocial stressor). However, results regarding the comparisons of the HAS-psychosocial stressor correlations with the HAS-organizational constraints (nonsocial stressor) correlations were mixed. Moreover, contrary to what was hypothesized, correlations of HAS with interpersonal constraints and job context constraints were not significantly different in magnitude. HAS was shown to moderate the relationship between CWB and the stressors of interpersonal conflict and organizational constraints. Individuals high on HAS engaged in more CWB when stressors were high, whereas individuals low on HAS engaged in low levels of CWB overall. HAS partially mediated the relationship between NA and CWB, in addition to the relationship between trait anger and CWB. It fully mediated the relationship between Machiavellianism and CWB. The influence of Machiavellianism on the occupational stress process also was explored. It was expected that high Machiavellians would appraise and respond to stressors in a negative fashion. However, contrary to what was expected, Machiavellianism was positively associated with informational justice and negatively related to incivility and CWB. Furthermore, it was negatively associated with NA and HAS. An alternative explanation for the results regarding Machiavellianism was presented. Although all hypotheses regarding the effects of HAS were partially supported, results of this study were generally demonstrative of the merits of including attributional processes (i.e., hostile attribution style) in CWB research within the occupational stress framework.

In Primary Aldosteronism (PAL) excessive amounts of aldosterone cause sodium and water retention and, in many individuals, this leads to moderate to severely high blood pressure. Although the chemistry and physiology are increasingly well understood, including the outcomes of treatment on physical health, there has been no systematic study of the psychological dimension of PAL. Anecdotally, patients exhibit symptoms such as angry outbursts, irritability, anxiety and defensiveness, and partners of these patients sometimes mention poor anger control and brittle or unpredictable moods. This thesis reports a systematic study of anger and anxiety among patients undergoing treatment for PAL. Eighty-three patients were recruited over an 11-month period to a prospective, pre-post design study to determine if treatment was associated with change in psychological state. Participants completed the State-Trait Anger Expression Inventory (STAXI-2), State-Trait Anxiety Inventory (STAI) and Psychosocial Adjustment to Illness Scale (PAIS) questionnaires. Adrenal Vein Sampling confirmed overproduction of aldosterone in one or both adrenal glands. Patients with Aldosterone Producing Adenoma (APA) were offered adrenalectomy. As per usual treatment protocols, patients with Bilateral Adrenal Hyperplasia (BAH) were prescribed spironolactone or amiloride depending predominantly on severity of blood pressure and potassium levels. Post-test questionnaires were completed after 6-8 months. Analysis was by mixed design (between-within subjects) ANOVA. Participant numbers in the adrenalectomy group fell far short of expectations. Fourteen past patients who had undergone unilateral adrenalectomy completed a retrospective semi-structured questionnaire. This qualitative data was analysed to identify themes similar to quantitative data. At baseline, 'non-completers' (ie those who did not complete the post-test; n=19), were significantly more angry than 'completers' (n=50) in State Anger (p< .01), Trait Anger (p< .05) and Anger Expression Index (p< .001). Trait Anxiety was also higher (p< .05), as was Psychological Distress (p< .05). Among those who participated at both interviews, there was small but statistically significant adverse treatment effect with higher scores for State Anger (p< .05), and Feeling Angry (p< .05). However for Trait Anger (p< .01), and 2 of its 3 sub-scales Angry Temperament (p< .05) and Angry Reaction (p< .01) there was a slight to moderate decrease in negative affect with treatment. Psychological Distress scores also improved (p< .05). Across all ANOVAs, there were no significant interaction effects, suggesting that any treatment effect was equivalent for the two drugs. Qualitatively collected data elucidated participants' changes in approach to life and relationships since adrenalectomy. Themes that emerged in the data included improved ability to cope with external stress, better control of emotions, more relaxed relationships and attitude to work, and a greater vitality and quality of life. Generally the comments were consistent with the drug treatments; there was noticeable benefit, including perceived better anger control and less anxiety. Positive psychological effects of treatment observed in the two drug groups were triangulated with data from a qualitative study. The combined evidence suggests that when excess circulating aldosterone is reduced (adrenalectomy), or blocked (spironolactone), or aldosterone's salt and water retaining effects are minimised (amiloride), then nervous irritability and its subsequent psycho-behavioural manifestations are reduced. The effect however is slight and the conclusions are weakened by an apparent attrition bias, and the absence of a control group. Implications for further research are discussed.
