Previous researchers have linked lower levels of stress and greater ability to mobilize energy toward a goal (self-motivation); confidence in their ability to complete/achieve a particular task or goal (self-efficacy), and ability to willfully control their thoughts, emotions and behaviour (self-control) to regular physical activity (PA). In an effort to provide further insight into the processes underlying regular PA researches have begun to explore the interplay among stress and multiple self-regulatory variables when predicting level of PA (i.e., intensity and duration). In line with this integrated approach the present study aimed to examine the interplay among self-motivation, self-efficacy, and self-control when predicting daily PA. The study was a correlational design with cross-sectional data on trait self-motivation and self-efficacy collected at baseline, and longitudinal data collected on stress, PA, state self-control, self-motivation and self-efficacy over a 2 day period. The results from the regression model (n = 418) revealed a negative indirect effect of stress on participants level of PA through its negative relationship with state multifactor self-regulation. This mediation effect appeared to be moderated by trait SE and SM. In conclusion, these results support the notion of a stress related depletion effect acting on individuals state self-regulatory resources which was associated with lower levels of PA (i.e. intensity and duration). However, the negative effect of stress appeared to be buffered by high levels of trait SE and SM.

Pharmacological cognitive enhancement is the use of prescription drugs to improve cognitive functioning in healthy individuals. Multiple ethical concerns have been raised by such use. The purpose of this project was to develop a reliable and valid measure to assess public attitudes about this issue. Participants were university students in Studies 1 (N = 465), 2 (N = 580) and 3 (N = 156). In Study 1 principal components analysis reduced the 90-item Attitudes Toward Pharmacological Cognitive Enhancement Scale to 42 items that loaded onto four components: Cheating/Unfairness, Motivation, Expected Benefits and Safety. Subscale scores differentiated users and nonusers. In Study 2 confirmatory factor analyses supported the model and statistically significant associations were found with related constructs such as attitudes toward performance-enhancing drugs, and prescription drug expectancies. In Study 3 test-retest reliability over a 3-week interval was above .70 for 3 of 4 subscales. Implications and future directions are discussed.

Social scientists have debated whether religious involvement is associated with differences in deviant behaviours for over a century. Religious practices and beliefs are often associated with less deviant behaviours in young adults, such as less frequent drug use and law-breaking. Empirical results on these associations, though, have been mixed, possibly due to heterogenous measures. Recent literature has begun teasing apart religious practices (e.g., attending church) from spiritual beliefs (e.g., believing in higher powers) and exploring their unique associations with different outcomes. The present study tested the independent and interactive effects of religion and spirituality in predicting deviance. Religion was negatively associated with some types of deviance, the relationship remained significant even after controlling for covariates. Spirituality was not reliably associated with deviance. There was an interaction between religion and spirituality, where the combination of the two was associated with the lowest level of deviance. Further findings and implications are discussed.

The traditions of spirituality and meditation have been found to connect to psychological health in the form of increased happiness, empathy, and decreased anxiety. The present study aimed to better understand how these practices might connect to such beneficial outcomes. A sample of 363 undergraduate student participants completed a questionnaire that measured their meditation practice, mindfulness, spirituality, happiness, empathy, and anxiety. Contrary to expectations, meditators and non- meditators did not significantly differ in their psychological health outcomes. These findings have implications for how meditators and non-meditator groups should be differentiated in research. Regarding spirituality, the purpose and meaning and innerness dimensions of the construct significantly predicted happiness and decreased anxiety, while the unified interconnectedness dimension significantly predicted empathy. The transcendence dimension of spirituality did not significantly predict psychological health. This pattern of results has implications for spiritual care interventions that intend to augment psychological health.

Sexual agency is receiving more attention in sexuality research though its contribution to sexual well-being has yet to be determined. Sexual agency has been theorized as an overarching concept comprised of both internal and external components. Both feelings and behaviours in the sexual domain can be impacted by prevalent culturally prescribed sexual scripts. The present study assessed sexual assertiveness, sexual self-concept, and comfort in sexual communication (i.e., together conceptualized as sexual agency) to determine if greater levels of these indices led to more direct consent communication, more intrinsic motivations for engaging in sex, and more positive sexual evaluations. Analyses were run separately on two samples: a student and community participant pool. Results indicate that greater sexual agency predicts being more intrinsically driven to engage in sex, using more direct consent communication, and reporting more positive evaluations of one's most recent sexual encounter. Gendered analyses reveal that cismen and ciswomen have similar levels of sexual agency, and rate their encounters similarly. Having greater sexual agency was a better predictor of experiencing sexual well-being compared to gender. Implications for policy development and sexual education curriculum reform are discussed, and future research directions are suggested.

Despite the extensive application of Baumrind's parenting style typology, some argue that it may not adequately capture the implicit warmth Chinese parents embrace. This study attempted to examine whether mind-mindedness could be a key indicator for helping children understand the benevolent intentions behind their mothers' authoritarian parenting practices. Specifically, this study investigated the variations in parenting styles, mind-mindedness, and children's behavior problems in Canada and China, the relationship among these variables, and the moderating effect of mind-mindedness on the relationship between authoritarian parenting and children's behavior problems. Participants were 83 Canadian and 136 Chinese mother-child dyads. Data on parenting styles, mind-mindedness, and problem behaviors were collected from maternal reports and lab observations. As expected, while Chinese mothers exhibited more authoritarian tendencies than Canadian mothers, their mind-mindedness buffer against the negative effect of maternal high-power strategies on children's behavior problems after controlling for maternal age and education. These results provide new perspectives on understanding Chinese parenting.

Sexual health education (SHE), specifically formal SHE, can play a key role in offering individuals the necessary information, motivation, and skills needed to maintain and improve their sexual health. This study used a survey-based approach to explore the relationship between Canadians' (N = 675) perceived quality of SHE and their feelings and behaviours related to sexual consent and communication, at two time points. This study was informed by two theoretical approaches: sexual script theory and the theory of planned behaviour. Hierarchical regressions were employed to determine how much the participants' education and demographics explained their attitudes, feelings, and behaviours. Perceived quality of SHE predicted consent feelings, and consent and communication behaviours during participants' first sexual experience, and only verbal communication during their most recent sexual experience. This research has furthered our understanding of the long-term impacts of SHE on feelings and behaviours related to sexual consent and communication.

Transracial adoption places the child with a family of a different ethnicity than their own. In the current study we qualitatively examine concerns associated with transracial adoption and investigate the relation between parent-child relationships and child social-emotional problems. Twenty-two adopted girls from China, 20 nonadopted Caucasian girls, and 23 nonadopted Chinese-Canadian girls, between 10-14 years, and their mothers were included. Thematic content analysis of interviews with adoptive mothers revealed that the transracial adoption experience had positive, negative, and neutral aspects. This included the parent-child relationship, the adopted child's view of their physical appearance, and the incorporation of cultural elements into the home. Quantitative analyses revealed no significant differences between the three groups on measures of parent-child relationship quality and child social-emotional functioning, which confirmed findings from the qualitative analysis. In the entire sample there were significant negative relations between quality of parent-child relationship and social-emotional functioning. These results suggest that early age of adoption may help decrease the likelihood of problematic parent-child relationships and social-emotional functioning in adopted children. It would be important to re-examine this question during adolescence when racial identity forms.

ABSTRACT Patients who undergo chemotherapy often complain of a persistent 'brain fog' that can be present up to years after treatment ends. This fog is expressed as marked impairments in areas of learning, memory and mental health. As it stands, researchers have yet to determine the mechanism at fault for these impairments. The present experiment investigates if the neurogenesis that takes place in the subgranular zone of the hippocampus is suppressed as a result of chemotherapy treatment, and results in these impairments. In the following thesis, two models of chemotherapy are used to explore the treatment effects on Long-Evans rats. From here, three behavioural assessments and three measures of immunohistochemical techniques are used to explore the effects of Temozolomide on memory and anxious behaviour. Our findings support the current literature that suggests that Temozolomide suppresses adult hippocampal neurogenesis and results in cognitive and emotional impairments.

Studies that have investigated the relation between social anxiety and theory of mind or executive function have shown that individuals with deficits in these cognitive processes have high levels of social anxiety. However, methodological problems make past findings questionable and difficult to interpret. The current study investigated whether deficits in theory of mind and executive function predicted symptoms of social anxiety in 99 older adolescents and young adults (18-29). On average, participants had moderate levels of social anxiety. Performance on measures of theory of mind and executive function did not predict symptoms of social anxiety. This lack of associations could be due to characteristics of the current sample, methodological differences in the current study compared to past studies, or the type of social anxiety and theory of mind measure used. Implications and directions for future research are discussed.
