Over the past 20 years, our understanding of emotional processes has grown rapidly. Within the study of emotion, a key area of interest has been how individuals succeed or fail in regulating emotional responses. Although still in its early development, researchers in this field have made progress in identifying the neurological, psychological, and social processes that underlie emotion regulation and dysregulation. Despite these advances, relatively few of these insights have been considered in light of the highly emotional terrain of couple distress. In the present study, one hundred and eight cohabiting couples rated themselves and their partner on key emotion regulation variables (e.g., the tendency to lose control of one??s emotions and the ability to restore emotional control and equilibrium). Analyses using the Actor- Partner Interdependence Model (APIM) showed strong links between these variables and individuals?? experience of intimacy and distress in their relationship. Results suggest that there are multiple avenues through which emotion regulation impacts a given individual??s relationship functioning; these include: (1) the individual??s self perceived capacity for emotion regulation, (2) their partner??s self-perceived capacity for emotion regulation, (3) the individual??s perception of their partner??s capacity for emotion regulation, and (4) the partner??s perception of the individual??s emotion regulation abilities.

This pilot study examined the effectiveness of Emotionally Focused Couples Therapy (EFT) compared to Treatment As Usual (TAU) in improving cortisol functioning among distressed couples. It also investigated the role of gender in cortisol functioning. Measures for cortisol were collected at five time points, both at pre- and posttreatment. Data were collected from a total of 60 couples, 20 of which received EFT and 40 of which received TAU. Overall, results from a two-way analysis of variance suggest that there are no significant differences between men or women, nor among couples in EFT and TAU, in posttreatment cortisol functioning. Directions for future research are discussed.

Background: Group CBT approaches have been shown to be equally as effective as individual CBT for reducing depressive symptoms and preventing relapse; however, the predictors of response are poorly understood. The primary objective of the studies presented in this thesis was to further examine the formal and process factors within group CBT for depression that contribute to various treatment outcomes. The first study investigated the relationship between group CBT for depression and changes in interpersonal distress, as well as the process mechanisms that might influence this relationship. The second study assessed whether formal feedback provided to therapists and clients derived from the Outcome Questionnaire (OQ-45), a robust measure of client functioning, would enhance group processes and treatment outcomes. Method: Study 1: Secondary data from clients having received individual CBT for depression at a community-based mental health training centre constituted one condition (18 clients). Data for the group condition (12 clients) were collected from clients attending group CBT for depression at a tertiary care facility. Relationship distress, as measured by the OQ-45 relationship distress subscale score, was assessed at intake and termination. Group participants also completed process measures at the start and end of treatment. In study 2, participants were recruited from a tertiary care facility to participate in a CBT group for depression. Participation involved completing brief questionnaires assessing psychological and process variables before and after treatment, as well as the OQ-45 at every session. Three groups (21 clients) received standard CBT and two groups (12 clients) received enhanced CBT, which included feedback about their progress from the OQ-45. Results: Results of study 1 suggest that clients who participated in group CBT experienced a significantly greater reduction in relationship distress across time than clients who participated in individual CBT. Results also indicate that therapeutic alliance, and not group cohesion, mediates the relationship between pretreatment relationship distress on posttreatment relationship distress in group CBT. Results of study 2 indicate that participants in the enhanced condition experienced greater improvements in quality of life, dysfunctional beliefs, and therapeutic bond at termination, relative to participants in the standard condition. Trends also suggest a greater reduction in depressive symptoms. Conclusions: Group CBT for depression may be more effective than the individual modality for reducing interpersonal distress. Furthermore, therapeutic alliance plays a significant role in improving interpersonal distress within a structured group CBT protocol. Feedback from the OQ-45 may help improve client outcomes and enhance therapeutic bonding with facilitators in group CBT for depression.

Couples experiencing relationship distress often require professional help, such as counseling and couple and relationship education (CRE). Research recently discovered that among couples in counseling, a circular relationship exists between individual and relationship distress-stress begets stress. Until this study, a similar examination had not been conducted among couples selecting CRE. This study examined the relationship between individual and relationship distress among married couples that had children, were from predominantly low-income and racially and ethnically diverse backgrounds, and selected CRE. A correlational research design was employed and framed in the social interdependence theory. The actor-partner interdependence model was conducted within a three-level hierarchical model. The results confirmed that a circular relationship exists between individual and relationship distress-distress begets distress. Within the circular model of individual and relational functioning, personal individual distress predicted partner individual distress as well as personal and partner relationship distress, and personal relationship distress predicted personal individual distress and partner relationship distress. The extent to which distress begot distress was stronger among women, those with low income, and those who were unemployed. The results also revealed a continuum of individual and relational functioning. Dyad members interact along a continuum from intrapersonal individual functioning to interpersonal relational functioning. The continua meet at the nexus of negotiation or the heart of interpersonal interaction, where dyad members communicate and make decisions, among other actions. Implications related to the findings of this study as well as inspirations for future research are discussed.

Thèse de doctorat présenté en vue de l'obtention du doctorat en psychologie - recherche intervention, option psychologie clinique (Ph.D) / Bien que les relations amoureuses puissent enrichir la vie d’un individu et favoriser son bien-être, elles peuvent également être une source de détresse lorsque des difficultés conjugales surviennent. Les comportements positifs et négatifs émis par les partenaires pourraient avoir un rôle important à jouer dans la satisfaction et l’engagement conjugaux et sont donc souvent ciblés dans le cadre de la psychothérapie conjugale. Cependant, peu d’études se sont intéressées simultanément à ces deux types de comportements pour comprendre leur contribution relative au fonctionnement relationnel. De plus, la présence d’insécurités d’attachement (anxiété d’abandon et évitement de l’intimité), fréquentes chez les partenaires qui consultent en thérapie de couple, pourrait teinter la manière dont ces comportements sont perçus. Ainsi, il semble important de réaliser des études s’intéressant à la fois à la perception des comportements positifs et négatifs du/de la partenaire et aux insécurités d’attachement dans l’étude du lien entre ces variables et le fonctionnement relationnel. Bien que plusieurs études se soient intéressées à ces facteurs de manière indépendante, peu d’entre elles les ont considérés conjointement afin d’atteindre une compréhension plus nuancée du lien entre ces variables. De plus, très peu d’études se sont intéressées à ces variables chez les partenaires de couples en situation de détresse conjugale, un contexte pouvant aussi affecter les perceptions d’un individu à l’égard des comportements de son/sa partenaire. Cette recherche doctorale vise à mieux comprendre les liens entre la perception des comportements positifs et négatifs, les insécurités d’attachement et des indicateurs de fonctionnement relationnel chez les couples consultant en thérapie conjugale. La première étude s’est intéressée aux liens entre la perception de deux comportements du/de la partenaire, un positif (soutien conjugal) et un négatif (violence psychologique), et deux indicateurs de fonctionnement relationnel chez les deux partenaires : la satisfaction conjugale et la volonté d’investir dans la relation. Cette étude s’est aussi intéressée au rôle modérateur de l’anxiété d’abandon dans ces associations. La deuxième étude s’est intéressée aux liens entre les insécurités d’attachement et le sous-engagement des deux partenaires en considérant la perception des comportements positifs et négatifs du/de la partenaire en tant que variables intermédiaires. Dans l’ensemble, les résultats obtenus suggèrent que les comportements positifs pourraient être particulièrement importants pour expliquer le fonctionnement relationnel des partenaires en situation de détresse conjugale. Les comportements négatifs seraient également associés à leur fonctionnement relationnel, mais dans une moindre mesure que les comportements positifs. La première étude a aussi permis de démontrer que le lien entre le soutien conjugal perçu de la part du/de la partenaire et le fonctionnement relationnel varie en fonction du niveau d’anxiété d’abandon d’un individu, bien qu’il y ait des différences de genre. La deuxième étude a démontré que la perception des comportements positifs du/de la partenaire pourrait constituer un mécanisme impliqué dans l’association entre les insécurités d’attachement et le sous-engagement des partenaires. Nos résultats suggèrent que l’augmentation des comportements positifs, tout en favorisant leur perception par les partenaires, pourrait constituer un facteur-clé des interventions visant à améliorer le fonctionnement relationnel des partenaires en situation de détresse conjugale. / While romantic relationships can enrich an individual's life and promote their well-being, they can also be a source of distress when relational difficulties arise. Positive and negative partner behaviors could have an important role to play in relationship satisfaction and relationship commitment and as such, they are often targeted in the context of couple therapy. However, few studies have considered these two types of behaviors simultaneously to understand their relative contribution to relationship outcomes. In addition, the presence of attachment insecurities (attachment anxiety and attachment avoidance), which are frequent among partners who seek couple therapy, could change the way that these behaviors are perceived. Thus, it seems important to carry out studies focusing both on the perception of positive and negative partner behaviors and on attachment insecurities in the study of the association between these variables and relationship outcomes. Although several studies have investigated these factors independently, few studies have considered these factors together to achieve a more nuanced understanding of the association between these variables. Moreover, very few studies have looked at these variables in partners of relationally distressed couples, a context also likely to affect an individual's perceptions of their partner's behaviors. This doctoral research aims to better understand the links between the perception of positive and negative partner behaviors, attachment insecurities, and relationship outcomes among couples seeking couple therapy. The first study focused on the links between the perception of two partner behaviors, one that is positive (support) and one that is negative (psychological aggression), and two relationship outcomes in both partners: relationship satisfaction and the willingness to invest in the relationship. This study also investigated the moderating role of attachment anxiety in these associations. The second study investigated the links between attachment insecurities and both partners’ under-commitment by considering the perception of positive and negative partner behaviors as intermediate variables. Overall, the results suggest that positive partner behaviors could be particularly important to explain relationship outcomes in relationally distressed partners. Negative behaviors would also be associated with relationship outcomes, but to a lesser extent than positive behaviors. The first study also showed that the link between perceived partner support and relationship outcomes varies with an individual’s level of attachment anxiety, although there are gender differences. The second study showed that perceived positive partner behaviors may be a mechanism involved in the association between attachment insecurities and both partners’ under-commitment. Our results suggest that increasing positive behaviors, while also promoting their perception by the partners, could be key for interventions aimed at improving relationship outcomes in relationally distressed partners.
