When romantic partners’ personal goals conflict, this can negatively affect personal goal outcomes, such as progress. In a concurrent mixed methods study, we investigated whether goal conflict and negation of goal conflict were associated with goal outcomes (progress, confidence, motivation) and what strategies partners used during the COVID-19 pandemic to negotiate goal conflict. Survey participants ( n = 200) completed a daily diary for a week and weekly longitudinal reports for a month and interview participants ( n = 48) attended a semi-structured interview. Results showed that higher goal conflict was associated with lower goal outcomes, and successful negotiation of goal conflict was associated with better goal outcomes. Qualitative analyses identified three goal conflict negotiation strategies (compromise, integration, concession). Conversations focused on both practical and emotional needs and included respectful communication and space from conflict (timeout or avoidance). The mixed methods results suggest that goal conflict was low during the pandemic and participants were often able to negotiate goal conflict resulting in better goal outcomes.
