Abstract
BACKGROUND: The researcher's previous study indicated that couples in a relationship where one partner is diagnosed with borderline personality disorder (BPD) experience intra- and inter-personal difficulties affecting interaction with self and others. Therefore, constructive intra- and inter-personal relationships are essential to facilitate the mental health of couples in a relationship where one partner is diagnosed with BPD. However, the concept has not been defined and applied in caring for such couples. AIM: The study aims to clarify its meaning by identifying and defining the central concept of 'facilitation of constructive intra- and inter-personal relationships'. SETTING: The researcher used results from a previous study that explored the experiences of couples in a relationship where one partner is diagnosed with a mental illness to identify and define the central concept. METHODS: The concept was examined using analysis, synthesis, and inductive reasoning strategies, which were applied in two phases. RESULTS: The central concept of 'facilitation of constructive intra- and inter-personal relationships' for couples where one partner is diagnosed with BPD was identified and defined using a dictionary and subject definitions. CONCLUSION: Identifying and defining the central concept is essential to developing a model to facilitate constructive intra- and inter-personal relationships. CONTRIBUTION: The concept 'facilitation of constructive intra- and inter-personal relationships' is unique in its form and valuable for developing a model that can be used as a guiding tool for psychiatric nurses to facilitate the mental health of such couples. Furthermore, the model could benefit other relationships experiencing intra- and inter-personal challenges.
