Research suggests that nurses have negative perceptions and subsequently negative interactions with patients diagnosed as having Borderline Personality Disorder (BPD). However, this research is mainly quantitative in nature and does not allow nurses to speak freely about their experiences of working with this client group. The purpose of this study was to explore nurses' relationships with BPD patients from their own perspective. Semi-structured interviews were used to elicit the participants' experiences of BPD patients and thematic analysis was used to raise themes from the data. One core theme and four major themes were identified. The core theme was: 'Destructive Whirlwind', which refers to the nurses perceiving these patients as a powerful, dangerous, unrelenting force that leaves a trail of destruction in its wake. The major themes were: care giving; idealized and demonized; manipulation and threatening. The study concludes that nurses experience BPD patients in a negative manner. This can be attributed to the unpleasant interactions they can have with them and feeling that they lack the necessary skills in working with this group. The results also indicate that nurses want to improve their relationships with BPD patients.
