This study investigated the relationships among attachment styles, affect regulation, and outcome in a clinical sample receiving treatment for depression. Sixty-six clients completed questionnaire measures of adult attachment, dysfunctional attitudes, interpersonal problems, self-esteem, and depression. Clients’ levels of affect regulation were assessed with an observer-rated measure of affect regulation. The study’s purpose was to extend previous research by examining the relationship between adult attachment and affect regulation within a clinical context. Results indicated significant and positive associations between clients’ attachment security and their levels of affect regulation at early and late stages of psychotherapy. Late modulation of expression and arousal were found to mediate the relationship between pre-treatment attachment insecurity and outcome. Pre-treatment attachment avoidance, characterized by high discomfort with closeness, had a direct relationship with depressive symptoms not mediated by the cognitive-affective processes of affect regulation. Implications of present findings for the treatment of depression are discussed.

The purpose of these studies was to examine moderation processes for the influence of early maternal parenting practices on young children’s prosocial outcomes. Data for both studies were drawn from the Kids, Families, and Places study. Observational measures of mothers’ parenting practices and children’s cooperation outcomes were collected in the home, and both mothers and fathers reported on their children’s prosocial conduct. Study 1 was a longitudinal analysis of the interaction between maternal sensitivity after birth (Time 1) and children’s joint attention (JA) skills (Time 2, 18 months later) on children’s cooperation skills at 18 months. Findings indicated that children’s concurrent Responding to JA (RJA) was associated with cooperation and early maternal sensitivity moderated this relationship. Children high in RJA showed good cooperation irrespective of maternal sensitivity. However, low RJA was associated with high cooperation in the presence of high maternal sensitivity. Study 2 used person-oriented analyses to examine patterns of maternal parenting associated with young children’s concurrent prosocial behaviour across socioeconomic contexts. Latent Profile Analysis identified 3 profiles of parenting: Positive (14%), Negative (36%), and Combined (moderate levels of both positive and negative practices; 50%). Mothers from low-income families and those living in disadvantaged neighbourhoods were more likely to  belong to the Negative or the Combined profiles.  Moderation analyses indicated the protective influence of the Combined profile of parenting for children residing in impoverished socioeconomic contexts. In the context of low family SES and high neighbourhood disadvantage, children were rated as more prosocial if mothers use a combined style of parenting. A protective-enhancing effect was found, in which these high-risk children were actually rated better than those children who did not live in such adversity. Together, results highlight the importance of studying the association between parenting and prosocial outcomes within an ecological and contextual framework, with interactions amongst both child-level and distal factors, for understanding individual differences in prosocial development.

The current thesis directly investigated whether changes in the neural correlates of self-regulation (SR) are associated with the effectiveness of treatment for children’s externalizing problems. In order to test this, seventy-one children 8–12 years of age with clinical levels of externalizing behaviour and their parents completed a 12-week cognitive behavioural therapy program (12 sessions) with a parent management training component that was aimed at improving SR. Electroencephalogram (EEG) correlates of SR were evaluated before and after treatment with a go/no-go task requiring inhibitory control on the children. Results showed that event-related potential (ERP) correlates of SR, such as the frontal N2 and frontal P3 event-related potential magnitudes, differed between the clinical sample and a matched comparison group before treatment: the clinical sample had larger N2 magnitudes and smaller frontal P3 magnitudes. Children who showed improvement (45%) with treatment demonstrated a decrease in the magnitude of the N2 in comparison with children who did not improve. For improvers only, source analysis during the time period of the N2 modeled activation decreases in dorsomedial and ventromedial prefrontal cortex as well as the anterior medial temporal lobe. A decrease in N2 magnitudes and corresponding reductions in source activation, in children who improved with treatment, might reflect improved efficiency in the neural mechanisms of SR. These findings may be important steps toward a better identification of neural markers of SR and a better understanding of the mechanisms of treatment efficacy.

HIV incidence continues to rise in the population of gay and bisexual men (Joint United Nations Program on HIV/AIDS, 2008), a high-risk group due to the complexity of promoting sexual behavior change on an enduring basis. In the present study, interview data from fifteen self-identified gay or bisexual men living in an urban Canadian city was analyzed in order to determine the most salient psychosocial factors in decision-making leading to safe sexual choices, and the psychological implications of these factors for the mental health and well-being of participants. Results suggest three core factors are most relevant to sexual decision-making for gay/bisexual men: self-efficacy, sexual communication and/or negotiation, and individual assessment of risk. A conceptual model of factors influencing sexual decision-making is presented. These results are discussed in terms of their implications for future HIV prevention interventions and the clinical practice of counselling psychology with gay and bisexual male clients.

In order to assist people in making positive changes of problematic behaviour it is necessary to examine how people change and what factors influence the process. Criminal offenders represent a group of individuals who often have difficulty desisting from problematic behaviour and continue to engage in illegal activity. Offenders in provincial correctional institutions were administered questionnaires to determine stage of change and processes utilized as outlined in the Transtheoretical Model (TTM) of change (Prochaska & DiClemente, 1984). Additionally, offenders were asked about their visions of the future using the Possible Selves (PSs) Model (Markus & Nurius, 1986). Taken together, this study looked at the contribution of the PSs Model to our understanding of the TTM, which has been criticized in recent years as lacking therapeutic significance for treatment providers as they guide individuals through the change process. More specifically, this study compares chronic criminals with first time offenders on psychological variables such as readiness for change, vision of possible selves, and hope for the future, as well as on legal variables such as risk for recidivism and institutional behaviour. The results indicate that most offenders acknowledged their behaviour as problematic and some even reported they were actively taking steps to change; however, chronic offenders admitted having less hope than first time offenders. Interestingly, both groups rated similarly on the dimensions of PSs. The outcomes would suggest that research efforts to incorporate other complimentary theories of change into the TTM, like the PSs model, may be helpful for understanding the process of change. While it seems these models may not be useful for predicting institutional behaviour, the data perhaps demonstrates the complexity of criminal behaviour and speaks to the necessity of further research in this population.

The purpose of this study was to explore protective factors that help women resist societal pressures for thinness. The present study used a qualitative life history methodology to examine the experiences of women who identified themselves as resilient to pressures to be thin and as liking their bodies regardless of size. In-depth semi-structured interviews were conducted with 14 women, ages 18 to 25, representing diverse social and ethno-cultural backgrounds and body physiques. In the interviews, the participants were inquired about their experiences related to anything they felt was helpful for them in developing a positive body image from childhood, adolescence, and to present day. The interviews were transcribed and analyzed for themes using constructivist grounded theory methodology. Data analysis was informed by the feminist theoretical approach, with attention paid to social and contextual factors. Three core categories emerged from the analysis, which included protective factors associated with participants’ experiences of identity, ways of inhabiting their bodies, and the nature of social influences in their lives. This research highlighted the women’s active role in maintaining a resilient stance in the face of pressures for thinness as well as the importance of social factors that assist them in this process.

Doctor of Philosophy / Department of Family Studies and Human Services / Anthony Jurich / This study used a qualitative approach as a means of exploring the decision-making process of women's participation in marital infidelity. Due to the growing prevalence and negative effects of marital infidelity, it is important for both clinicians and researchers to understand its occurrence. Although there has been a significant amount of research on marital infidelity in recent years, there is not any significant research that looks at the process occurring in both the marital and extramarital relationships. This study focused on examining the process an individual goes through when making the decision to have an affair, particularly, how they were able to give themselves permission to have an affair. Semi-structured interviews were conducted with four female participants who had participated in marital infidelity. The interviews were audio taped, transcribed, and analyzed using the transcendental phenomenological model (Moustakas, 1994). Four categories and 14 themes emerged, regarding the decision-making and permission-giving processes of women’s participation in marital infidelity. The women reported a lack of quality time spent with their husbands, as well as a lack of attention they received from their husbands. The women also discussed an inability to solve conflict within their marriage. The women reported developing relationships, outside of their marriage, either with ex-flames, old friends, or new friends, all of whom became their affair partner. The women reported the support of family and/or friends for the extramarital relationship, along with receiving positive attention from their affair partner. The women discussed the moral values as being a deterrent to marital infidelity, but did not perceive enough barriers or protective factors as preventing them from moving forward with the affair. Finally, the women described ways in which they were able to limit cognitive dissonance as a means of giving themselves permission to move forward with the affair. Clinical and research implications were discussed, as well as, the limitations of the current study.
