Abstract
Difficulties in problem-solving constitute one of the main causes of conflict within romantic relationships, especially when there are communication limitations and discrepancies in interests, needs, expectations, or values. In this context, conflict resolution techniques are understood as psychological and communicative strategies aimed at transforming differences into opportunities for positive adjustment, promoting emotional regulation and strengthening affective bonds. This systematic review analyzed studies published between 2018 and 2025 that describe techniques applied to couples to improve conflict management. Research in both Spanish and English, including primary and secondary studies, was included due to the limited availability of updated literature on the topic. Studies focused on family, workplace, or other types of relationships were excluded. The search was conducted in five databases: Scopus, PubMed, SciELO, Redalyc, and Google Scholar, with support from the Rayyan tool. The PRISMA 2020 criteria were then applied for study selection, and methodological quality was assessed using CASPe guidelines. The results were organized descriptively according to the type of technique reported. After the screening process, five relevant studies were identified. Among the techniques with the best outcomes were guided mediation, mindfulness, emotional validation, and assertive communication, all associated with improvements in relationship quality, reduced conflict levels, and strengthened emotional regulation. Additionally, relational factors such as cooperation and communication quality were found to play a decisive role in the effectiveness of these interventions.
