Demystifying Toxic Romantic Relationships: Identifying Behaviors and Post-Breakup Outcomes

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.
