Media has had a significant influence on how individuals living with and at risk of Human Immunodeficiency Virus (HIV) care for their health. This research builds on previous research to explore the link between HIV related media messaging and HIV related health behaviours using a mixed methods approach. To investigate the access to and perceptions of HIV related media, a sample of 129 individuals took part in an online survey and 13 were assessed in follow up semi-structured interviews. People living with HIV, people at risk of HIV, and participants not in those groups differed on a number of HIV media access variables, including the amount of time spent interacting with HIV related media, how they accessed it, and its perceived effects on their HIV related attitudes and behaviours. Interviews explored these differences more, finding that while current HIV related media is less stigmatizing and more factual than the past, most current HIV related media is distributed via social media and is accessed by a relatively small group of HIV specialist viewers. The history of HIV related media continues to play an important role in determining perceptions of HIV related media. Implications of this study will inform strategies for the communication of HIV health messages.

Sexual assertiveness encompasses skills in refusing unwanted sexual situations and bringing about wanted sexual situations. Measures of sexual assertiveness typically assess both refusal and initiation aspects, yet there is a dearth of research examining these skills in relation to one another. The present study examined the relationship between these skillsets in women, exploring predictors of each. Initiation and refusal assertiveness were moderately correlated. Additionally, the relationship between them was not entirely explained by general assertiveness, indicating that there is something unique to assertiveness in the sexual context. Committed relationship context and erotophilic disposition specifically predicted initiation assertiveness. Less endorsement of the sexual double standard and fewer approach motivations for engaging in unwanted sex specifically predicted refusal assertiveness. Few differences emerged in predictors of assertiveness types when comparing sexual orientation groups, yet non-heterosexual women reported slightly lower levels of refusal assertiveness. Implications for sexual education, therapy, and future research are discussed.

Previous research has found that bullying and victimization is related to poor socioemotional competencies. The present study examined the relationship between emotional intelligence (EI) and bullying and victimization in a large community-based sample of adolescents. Specifically, we explored the EI of bullies, victims, bully-victims, and those uninvolved. We also examined whether the relationship between EI and types of bullying and victimization activities were consistent across age and gender. We found that stress management and interpersonal skills are important EI dimensions to predicting both bullying and victimization. Moreover, intrapersonal skills were predictive of boys' bullying behaviours and adaptability was the strongest EI dimension in bullies and victims. Age did not contribute much to the overall prediction of bullying and victimization in either gender. Results are discussed in terms of future implications regarding anti-bullying interventions.

Autistic traits are characterized by difficulties with socialization, preference for order, and rigid and repetitive behaviour patterns. This study evaluated the psychometric properties of two measures of autistic traits, the Autism-Spectrum Quotient (AQ) and the Sub-threshold Autistic Trait Questionnaire (SATQ), and their associations with the HEXACO personality framework. The relationships between self-objectification, Need for Cognition (NFC), and autistic traits were also examined. In a student sample (N = 294), autistic traits were found to be negatively related to eXtraversion, but unrelated to self-objectification and NFC. However, individual subscales of the SATQ and AQ revealed different personality profiles, suggesting a non-unitary composition of the autistic trait measures. The AQ's subscales failed to be represented in its factor structure. Intercorrelations between SATQ and AQ subscales showed that some subscales were uncorrelated with others. These concerns challenge whether autistic traits should be considered as a downwards extrapolation of Autism Spectrum Disorder.

Trait Emotional Intelligence (EI) includes competencies and dispositions related to identifying, understanding, using and managing emotions. Higher trait EI has been implicated in post-secondary success, and better career-related decision-making. However, there is no evidence for whether it predicts the pursuit of post-secondary education (PSE) in emerging adulthood. This study investigated the role of trait EI in PSE pursuit using a large, nationally-representative sample of Canadian young adults who participated in the National Longitudinal Survey for Children and Youth (NLSCY). Participants in this dataset reported on their PSE status at three biennial waves (age 20-21, 22-23, and 24-25), and completed a four-factor self-report scale for trait EI (Emotional Quotient Inventory: Mini) at ages 20-21 and 24-25. Higher trait EI subscale scores were significantly associated with greater likelihood of PSE participation both concurrently, and at 2- and 4-year follow-ups. Overall, these associations were larger for men than women. Trait EI scores also showed moderate levels of temporal stability over four years, including full configural and at least partial metric invariance between time points. This suggests that the measure stays conceptually consistent over the four years of emerging adulthood, and that trait EI is a relatively malleable attribute, susceptible to change with interventions during this age period.

Children of incarcerated parents are an understudied at-risk population. However, this thesis was designed to advance our understanding of the effects of parental incarceration and factors that may influence the impact. Using quantitative methods, possible moderating roles of gender, number of incarcerated parents, and contact frequency on the associations between attachment representations and problem behaviours were investigated in two samples. Results revealed that the number of incarcerated parents and contact frequency with incarcerated parents moderated the associations between attachment and externalizing behaviours. Furthermore, after controlling for several factors (e.g., gender, number of incarcerated parents, and contact) higher scores on secure parental attachment representations were consistently negatively associated with internalizing symptoms and externalizing behaviours. The discussion of findings highlight the utility of attachment theory in conceptualizing the impact of parental incarceration and the importance of fostering attachment security to promote positive mental health and behavioural outcomes for children of incarcerated parents.

Evidence suggests that visuomotor system behaviour may be more sensitive to the prolonged effects of mild brain injuries than neuropsychological tests. We evaluated whether participants with a mild closed head injury (CHI) would show lingering visuomotor deficits, but not cognitive deficits, up to three years post-injury compared to participants with an orthopaedic injury and healthy controls. All three groups completed a tablet-based visuomotor assessment tool and a brief neuropsychological test battery. The CHI participants scored comparable to the control groups on the neuropsychological tests, but when assessed for visuomotor function requiring adjustment to a changing stimulus, CHI participants showed poorer performance than the control groups. Combined, these findings add to the evidence that CHI can lead to persistent visuomotor deficits that extend beyond those of neuropsychological tests. Therefore, visuomotor assessment should be included in brain injury and recovery evaluation, and this can be accomplished easily using tablet-based tasks.

Typically task interference is studied using reaching adaptation tasks (visuomotor rotation and/or force-field learning). Participants in these experiments are already experts at the base task (point-to-point, planar reaching) and their ability to adapt reaching to the imposed perturbation is studied. The pattern of data induced by the perturbation is used to make inferences about the nature and neural correlates of our learning and memory for reaching perturbations, specifically, and motor performance in general. We wanted to see if it is possible to demonstrate this same interference pattern using a novel vegetable-chopping task, where we can easily recreate natural performance settings using a task for which we can easily identify non-experts. Participants performed a chopping task in which they are asked to chop a sweet potato into 5 mm-wide slices, matching the beat of a metronome (120 bpm). Following this initial learning, participants were exposed to an interference condition. Participants then performed trials of the original task again. Interference was inferred if the second performance of the original task was impaired, compared to initial performance. Experiment 1 involved novice choppers, and either the force or frequency of chops was manipulated. Only the altered frequency task produced interference effects. In Experiment 2, competent and expert choppers had to manage either a faster or slower frequency. We found evidence for interference in competents, but not experts. These results support the idea that the vulnerability to interference of motor memory changes with practice, and so any inferences made about memory structure must take into account not only expert performance, but every level of skill.

Although a wealth of research supports nature's beneficial effects on well-being, a lack of attentiveness and appreciation for nature may prevent people from fully experiencing nature's benefits. A mindfulness-based nature intervention was tested across two studies to investigate whether gratitude and mindfulness can boost nature's effects for well-being. Students completed activities across a one-week (Study 1; N = 129) and two-week (Study 2; N = 130) intervention. Students in both studies experienced significant declines in positive and negative emotion over time. Study 1 did not show the expected increases in gratitude and connection to nature. Study 2 found that students who simply spent time in nature experienced fewer negative emotions and greater increases in trait gratitude than those who were asked to gratefully reflect on their natural surroundings. Both studies found positive correlations between trait gratitude, mindfulness, well- being and connection to nature. Implications and suggestions for future research are discussed.

Sexual script theory suggests that sexual behaviours have social meaning, and that individuals perceive certain behaviours as normative and expected. Previous research has indicated that there is a common belief in a cultural sexual script for (hetero)sexual behaviour sequences (CSSHS). Study 1 compared perceived norms with behaviours in first ever penile-vaginal intercourse (PVI) sex events, as well as first and recent events with most recent partners. Many participants reported the CSSHS as typical, but few reported personal experiences that followed the CSSHS. Script adherence was not strongly related to physical pleasure. Study 2 found that committed relationships predicted greater female pleasure in first ever PVI sex. This link was mediated by communication during sexual activity. Results are discussed in the context of sexual script theory. Findings suggest that common scripted assumptions regarding PVI sex events should be reviewed for their value and representation of norms.
