This dissertation demarks the start of an empirical study of toxic romantic relationships. Three primary tasks were undertaken: (1) uncover characteristics of toxic romantic relationships, (2) develop a Toxic Relationship Behaviors scale, and (3) determine how toxic relationship behaviors and coping behaviors associate with breakup distress and post-traumatic growth following breakup. For aim 1, an inductive qualitative analysis examined toxic romantic relationships behaviors mentioned in Reddit and Quora threads. Data (n = 1,615) were classified under 14 themes representing toxic relationship behaviors and indicated one partner predominantly engaged in toxic relationship behaviors, characterized by power, control, and self-centeredness. For aim 2, a survey was launched to develop a Toxic Relationship Behavior scale and investigate relationships among toxic relationship behaviors, breakup distress, post-breakup coping behaviors, and post-traumatic growth. Exploratory factor analysis showed six Toxic Relationship Behavior subscales: (1) isolating, (2) displaying righteous self-centeredness, (3) walking on eggshells, (4) criticizing and conveying contempt, (5) surveilling, and (6) engaging in intermittent reinforcement. For aim 3, a quantitative study (n = 168) was conducted using the Toxic Relationship Behaviors scale to determine how toxic relationship behaviors and coping behaviors associate with breakup distress and post-traumatic growth. Results indicated emotional breakup distress was positively associated with focusing on the ex and seeking social support. Cognitive breakup distress was positively associated with surveilling and displaying righteous self-centeredness, as well as coping by focusing on the ex, seeking social support, and solitude. Personal growth positively associated with intermittent reinforcement, walking on eggshells, and righteous self-centeredness, as well as the coping strategies positive distraction and seeking social support. Thus, the combination of displaying righteous self-centeredness, walking on eggshells, and productive coping associated with the highest levels of personal growth. Walking on eggshells and seeking social support also predicted heightened appreciation of relationships and increased sensitivity toward others after the breakup. Coping through positive distractions was also positively related to increased sensitivity to others. The final chapter discusses findings across both studies and outlines directions for future research on toxic relationship behaviors.

Emerging adulthood represents a liminal space between adolescence and adulthood. Attachment with a romantic partner is commonly developed during this time; however, the nature of the dating relationship often remains ambiguous and/or undefined. Dating provides emerging adults the opportunity to develop their romantic competence and navigate these particular attachment relationships. Conflict, and how it is managed, is a critical variable during this time and differentiates between couples who progress in their relationship from those who terminate. What is more, partners may become stuck in destructive cycles, or patterns, of conflict (i.e., demand-withdrawal). Using the theoretical frameworks of attachment theory and emotionally focused couples therapy, this study’s goal it to examine the impact of a brief writing-intervention on relational quality, secure attachment behaviors (i.e., accessibility, responsiveness, and engagement) and attachment dimensions (i.e., anxiety, avoidance). Sixty-seven participants were randomly assigned to one of three conditions for a two-wave study: (1) a treatment condition that was provided an educational presentation regarding couples’ negative cycles of interaction and attachment needs, followed by a guided writing task; (2) a comparison condition that only received the educational presentation; and (3) a control condition that received neither the educational presentation nor the writing task. Hypotheses proposed that participants in the treatment condition would experience increased relational quality, secure attachment behaviors (for both themselves and their partner), and greater secure attachment (i.e., decreased anxiety and avoidance) across time compared to the comparison and control conditions. Data did not support the hypotheses. These findings offer important implications for the development of future brief couples’ interventions and aim to generate future research.

The goals of this dissertation were to develop a measurement called the

Empathetic Expressions Scale (EES) for Negative and Positive Events, to evaluate expressions of empathy from the receiver perspective, and to provide initial evidence for empathetic expressions as a separate construct from the empathy experience. A series of studies were conducted using three separately collected sets of data. Through the use of Exploratory Factor Analysis (EFA), the EES for Negative Events and the EES for Positive Events were created from the emerged factors. A five-factor structure emerged for the EES for Negative Events, which include Verbal Affirmation, Experience Sharing, Empathetic Voice, Emotional Reactivity, and Empathetic Touch. This scale was found to have good convergent and discriminant validity through the process of construct validation and good local and model fit through Confirmatory Factor Analysis (CFA). A four-factor structure and two-factor structure emerged for the EES for Positive Events. The four factors include Verbal Affirmation, Experience Sharing, Empathetic Voice, and Emotional Reactivity. The two factors in the second structure include Celebratory Touch and Hugs.The final study focused on evaluating different empathetic expressions from the receiver perspective. From the receiver perspective, the participants rated five types of empathetic expressions in response to negative or positive events disclosure. According to the findings, Emotional Reactivity was rated as the most effective empathetic expression in negative events on both levels of supportiveness and message quality scales whereas Verbal Affirmation received the lowest ratings on both criteria. In positive events, Experience Sharing was evaluated as the most supportive and highest quality message whereas Verbal Affirmation was evaluated the lowest on both criteria. Taken together, the series of studies presented in this dissertation provided evidence for the development and validity of the EES for Negative and Positive Events.

The present study focused on those who had recently been involved in a romantic relationship that ended in a breakup. Data was collected from 326 participants using an online questionnaire. Participants were asked questions about goal linking, rumination, self-efficacy, Facebook ORI behaviors, and emotional response questions. The results indicated that there were two types of Facebook ORI behaviors: explicit and covert. Explicit ORI was predicted by self-efficacy among those whose partner ended the relationship, as well as goal linking when the breakup was self-initiated. Covert ORI was predicted by rumination across all levels of breakup initiator (self, partner, or mutual). Moreover, only general negative emotions predicted Covert ORI, but general negative emotion and positive emotion predicted Explicit ORI. Finally, the results showed that those who were broken up with engaged in more Covert ORI behaviors than those who ended the relationship themselves or who mutually ended the relationship. These results suggest that Relational Goal Pursuit theory, which is commonly used to explain ORI behavior, be reconceptualized.

Guided by Alberts, Tracy and Trethewey's (2011) integrated theory of the division of domestic labor, this dissertation examined the influence of domestic labor response threshold (i.e., the point at which one is sufficiently disturbed by a task undone so as to feel compelled to attend to it) on domestic labor performance and domestic labor conflict. Three-hundred-ten heterosexual participants (155 marital dyads; average marriage length of 20 years) completed an online questionnaire about their performance of household labor, household labor conflict, and response thresholds. Response thresholds were assessed using traditional verbal measures as well as two visual (i.e., photographic) measures developed for this investigation. The data were analyzed using three methods of dyadic data analysis: structural equation modeling, repeated measures multivariate analysis of variance (MANOVA), and actor-partner interdependence models using multilevel modeling. Results indicate that the lower one's response threshold, and the higher one's partner's response threshold, the greater one's contributions to household tasks. Additionally, the lower one's response threshold, and the higher one's partner's response thresholds, the more likely the demand-withdrawal pattern is to emerge in domestic labor conflicts. Finally, mutual avoidance is more likely when one partner perceives that it is less costly to complete domestic work than to engage in conflict about it, or when one partner perceives that domestic labor is not a worthwhile or appropriate conflict topic. Contributions of this investigation include support for the integrated theory of the division of domestic labor, increased understanding of how individual differences (working in concert with actor sex) contribute to domestic labor allocation and conflict, a more sensitive measure of response threshold, and preliminary evidence of the "logics" of avoidance of domestic labor conflict.

An offender's expression of remorse plays an important role following relational transgressions, yet it is not well understood how the experience and expression of remorse relate to both victim responses to hurt and forgiveness in close relationships. This study uses a social functionalist framework to investigate the role of remorse in the forgiveness process and tests whether offender remorse experiences mediate the associations between victim responses to hurt and remorse expressions. Undergraduate participants (N=671) completed questionnaires about a time when they hurt a close relational partner and reported their partners' responses to hurt, their own experiences and expressions of remorse, and their perceptions of forgiveness. Results indicated that victims' sad communication positively predicted offenders' other-oriented and affiliation remorse experiences; victims' threatening communication positively predicted offenders' self-focused remorse experience; and victims' conciliatory communication and withdrawal positively predicted offenders' affiliation and self-focused remorse experiences. Results of the mediation analyses revealed that self-focused remorse fully mediated the relationship between victim threatening communication and low status behaviors; other-oriented remorse partially mediated the association between victim sad communication and apology/concern behaviors; and affiliation partially mediated the relationship between victim conciliatory communication and connection behaviors. Victims' withdrawal behaviors and offenders' use of compensation were not related. Finally, offenders' apology/concern and connection behaviors associated positively with perceptions of forgiveness, whereas low status behaviors negatively predicted forgiveness. Use of compensation following a hurtful event was not significantly related to forgiveness. Results are interpreted within the framework of evolutionary psychology and further validate the functional approach to studying emotion.
