Characteristic affect may influence the development of resilience. Higher levels of resilience may in turn decrease the likelihood of individuals developing symptoms of depression. All first year psychology students (N = 217) were recruited in this longitudinal study to examine whether resilience mediates the relationship between characteristic affect and symptoms of depression. One hundred and seven students completed survey measures at the start of a semester and again 3 months later. Results indicated that greater negative affect predicted worsening of depressive symptoms over 3 months, while greater positive affect predicted a lessening of depressive symptoms over 3 months. Resilience fully mediated the effects of positive affect on change in depression and partly mediated the effects of negative affect on change in depression. These results are interpreted in the context of a hierarchical model of affect and the Broaden and Build Theory, which may explain how resilience arises from positive affect and mediates between affect and symptoms of depression over time.

This research experimentally investigated whether virtual reality experience can prompt greater empathy and whether greater engagement with a virtual reality connects this virtual reality experience to empathy. Randomly assigned participants viewed a documentary featuring a young girl living in a refugee camp either in a virtual reality format or in a control two-dimensional format. Results indicated that the virtual reality experience resulted in greater engagement and a higher level of empathy for the refugee girl compared to the control condition. Greater engagement was a process connecting the virtual reality experience to empathy. Virtual reality has the potential to influence interpersonal emotions such as empathy.

The enzyme telomerase, through its influence on telomere length, is associated with health and mortality. Four pioneering randomized control trials, including a total of 190 participants, provided information on the effect of mindfulness meditation on telomerase. A meta-analytic effect size of 'd' = 0.46 indicated that mindfulness meditation leads to increased telomerase activity in peripheral blood mononuclear cells. These results suggest the need for further large-scale trials investigating optimal implementation of mindfulness meditation to facilitate telomerase functioning.

Telomeres protect the ends of chromosomes, and short telomere length is associated with poor health and mortality. This study reports a meta-analytic investigation of the relationship between perceived stress and telomere length, including results from eight studies with a total of 1143 participants. A meta-analytic effect size of r = -0.25, p < 0.001, indicated that higher levels of perceived stress were associated with shorter telomere length. Examination of the studies for moderators of effect size identified some significant moderators, such as a difference in effect sizes between samples comprised of only women and mixed-sex samples. These results are only suggestive as they are based on a small set of studies, and funnel plot analyses indicated a publication bias. A significant relationship between more perceived stress and shorter telomere length is consistent with theoretical frameworks positing that stress induces physiological changes that result in shortened telomeres.

Two studies, with a total of 707 participants, developed and examined the reliability and validity of a measure for anticipatory traumatic reaction (ATR), a novel construct describing a form of distress that may occur in response to threat-related media reports and discussions. Exploratory and confirmatory factor analysis resulted in a scale comprising three subscales: feelings related to future threat; preparatory thoughts and actions; and disruption to daily activities. Internal consistency was .93 for the overall ATR scale. The ATR scale demonstrated convergent validity through associations with negative affect, depression, anxiety, stress, neuroticism, and repetitive negative thinking. The scale showed discriminant validity in relationships to Big Five characteristics. The ATR scale had some overlap with a measure of posttraumatic stress disorder, but also showed substantial separate variance. This research provides preliminary evidence for the novel construct of ATR as well as a measure of the construct. The ATR scale will allow researchers to further investigate anticipatory traumatic reaction in the fields of trauma, clinical practice, and social psychology.

The purpose of this meta-analysis was to quantify the relationship between the Five-Factor Model of personality and alcohol involvement and to identify moderators of the relationship. The meta-analysis included 20 studies, 119 effect sizes, and 7,886 participants. Possible moderators examined included: five-factor rating type (self vs. other); study time-frame (cross sectional vs. longitudinal); sample type (treatment vs. non-treatment); type of alcohol involvement measure used; gender of the participants; and age of the participants. The meta-analysis showed alcohol involvement was associated with low conscientiousness, low agreeableness, and high neuroticism, a personality profile that: a) fits on the low end of a superordinate personality dimension that has been called self-control; and b) makes treatment difficult. Several significant moderators of effect size were found, including the following: studies of individuals in treatment for alcohol problems showed a more negative pattern of personality traits than did other studies; crosssectional studies, but not longitudinal studies, showed a significant effect for agreeableness, perhaps suggesting that low agreeableness may have a different causal link to alcohol involvement from the other factors; mixed-sex samples tended to have lower effect sizes than single-sex samples, suggesting that mixing sexes in data analysis may obscure effects.

Objective: The present study examined the efficacy of bibliotherapy in assisting individuals experiencing distress related to tinnitus. Methods: One hundred sixty-two tinnitus sufferers from Australia participated in a study designed to examine the effectiveness of a cognitive–behaviorally based self-help book in reducing distress. To maximize the ecological validity of the findings, we excluded no individuals interested in treatment for tinnitus-related distress. Results: The experimental condition lost 35% of participants at postassessment, compared to 10% in the control group. In an analysis of participants who completed postintervention assessment, those assigned to the intervention condition, who received a tinnitus self-help book, showed significantly less tinnitus-related distress and general distress 2 months later compared to those assigned to the waiting list control condition. The intervention group's reduction in tinnitus-related distress and general distress from preintervention to postintervention 2 months later was significant, and these participants maintained a significant reduction in distress on follow-up 4 months after they received the tinnitus self-help book. A long-term follow-up of all participants, who at that time had received the book at least a year previously, showed a significant reduction in tinnitus distress. Although these group differences and pre–post changes were significant, effect sizes were small. Intention-to-treat analyses showed no significant effect for between-groups analyses, but did show a significant effect for the 1-year follow-up pre–post analysis. Conclusion: Information on the effectiveness of using a self-help book, without therapist assistance, in alleviating distress is important, as bibliotherapy can provide inexpensive treatment that is not bound by time or place.

Two studies set out to provide information regarding social environment contexts of trait emotional intelligence. In an initial exploratory study, participants with higher emotional intelligence were associated with close others of high emotional intelligence. A second longitudinal study examined the effect of social environments comprising higher or lower emotional intelligence on changes in emotional intelligence of residents in these environments. This study assessed the emotional intelligence and subjective well-being of residents of colleges at the start of a semester and again three months later. A higher composite college residence emotional intelligence index predicted an increase in participants' emotional intelligence and positive affect. These effects were especially strong for first-semester residents. The results offer new information regarding social environment contexts of trait emotional intelligence and extend findings regarding contagion of emotion and transmission of individual differences in complex emotion processing.

In recent years, the global community has suffered uncertainty and threats to safety due to a variety of events, including terrorist attacks, large-scale accidents, natural disasters, and international conflicts. Indirect engagement with these events is made possible through the media. Numerous studies have found negative psychological outcomes following indirect exposure to trauma, either via media coverage or through care of people directly impacted. If media has the potential to effect even small negative changes in psychological health, then cumulative or more intense exposure might lead to more substantive effects.
This thesis explored whether trauma-related media consumption and ensuing social discussions may trigger a unique form of distress, referred to as Anticipatory Traumatic Reaction (ATR). This construct is based on the dual scaffold of (1) the diagnostic criteria of posttraumatic stress disorder (PTSD) considered sub-clinically and (2) emotions, cognitions, and behaviours that have been associated with secondary exposure to trauma. Specifically, ATR is conceptualised as involving people overestimating future risk (for themselves or significant others) of traumatic events presented in the media and experiencing distress relating to feared outcomes. Affected individuals might engage in thoughts or behaviours designed to reduce uncertainty or prepare for adverse events and experience disruptions in day-to-day functioning.
A total of six studies (reported in the format of five stand-alone articles) were conducted. Study 1 was a quantitative meta-analysis of experimental studies that evaluated the overall effect of threat-related media on psychological outcomes. This study confirmed the association between trauma-related media exposure and negative psychological outcomes and provided evidence to support a causal pathway. Studies 2 and 3 (reported in a single journal article) generated a new psychometric measure to assess the novel construct of ATR and found preliminary evidence of this form of distress in a general population of Australians. Study 2 used exploratory and confirmatory factor analysis to construct a scale with three latent variables (feelings, preparation, and disruptions relating to ATR) and correlational analyses found evidence of convergent and discriminant validity for the scale. Study 3 provided additional validation of the scale, examined links with conceptually related variables pertaining to media consumption, and provided evidence for ATR as a construct that, despite some overlap, is separate and distinct from PTSD. The results also indicated that higher levels of ATR are associated with a greater degree of engagement with threat-related media and social discussions. Further, the results suggested that younger people might be at greater risk of ATR than older people, and that this may be partially accounted for by a greater proportion of social media news-gathering by younger people.
Study 4 explored possible links between ATR and a reaction to another form of secondary exposure to trauma – compassion fatigue, which occurs as a consequence of providing a caring role for traumatised individuals. The results suggested that high levels of ATR may exacerbate levels of depression, anxiety, and stress, potentially putting care workers at greater risk of job burnout. Study 5, a meta-analytic review of the efficacy of mindfulness interventions for treating PTSD, indicated that, across studies, mindfulness was effective in reducing symptoms of PTSD. Given some symptomatic and conceptual similarities between PTSD and ATR, this finding pointed to mindfulness as a potentially useful technique for mitigating ATR. The final study, Study 6, assessed proposed risk factors for ATR and used an online experiment with random assignment to test a series of brief interventions to attenuate ATR. The findings suggested that risk factors for experiencing higher levels of ATR included being female, being younger, living with a mental illness, repetitive negative thinking, intolerance of uncertainty, personal distress empathy, fantasy empathy, and a concern about world politics. Both a cognitive intervention to address probability neglect and a mindfulness intervention showed promise in attenuating momentary ATR.
The current research provides preliminary evidence for ATR as a newly identified psychological condition that may occur for some people in response to media exposure and social discussions of disasters and large-scale threats. If, as suggested by the results of this research, people with existing mental illness are at greater risk for ATR and that ATR might exacerbate existing symptoms, it will be important to identify vulnerable subsets of this population so that clinicians can intervene to reduce ATR and limit distress. Because media exposure to traumatic events is a basis for ATR, the findings have implications for presentation of media content. This thesis adds to the body of knowledge in the fields of trauma, social psychology, and clinical practice.
