Despite the worldwide proliferation of suicide-prevention crisis-line networks, there is limited in-depth knowledge of how the volunteer call responders experience and manage emotional stressors. The study's purpose was to explore emotional stressors related to operating a diaconal suicide-prevention crisis line, and how these are managed in daily operations. In this qualitative study, 27 volunteers were interviewed in four focus groups. The material was analysed using systematic text condensation. The participants experienced emotional stressors related to being unable to actively intervene, encountering traumatised callers and feeling uncertain about representing the Church. They used a combination of personal coping strategies and organisational support factors. Implications for training and practice are further discussed.
