WHAT IS KNOWN ON THE SUBJECT?: Nurses' experience challenges of managing risk, boundaries and emotional responses when working with people who self-harm. Adolescent self-harm is a growing problem, with rates increasing in the UK. Existing research has failed to differentiate and specifically explore nurses' experiences of working with adolescents who self-harm. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: This paper provides an understanding of the impact of working with adolescents who self-harm in the community on nurses, and highlights recommendations to improve staff and patient experiences and care. Community CAMHS nurses experience personal and professional conflicts when working with adolescents who self-harm. They experience interpersonal conflicts balancing the needs of adolescents with the needs of the systems around them, and intrapersonal conflicts regarding experiencing mixed emotions, and balancing the care they want to provide with service pressures. Community CAMHS nurses experience feelings of self-doubt and shame due to their emotional responses, self-care behaviours, personal and professional boundaries. They use their feelings of pride, honour and enjoyment to manage these experiences. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Nurses working in CAMHS should be provided with more opportunities for reflective practice and self-care, to enable reflection and learning regarding the emotional impacts and working with systems. Managerial investment is required to facilitate this. Nurses working with adolescents who self-harm in CAMHS could benefit from training regarding understanding and managing self-harm (such as dialectical behavioural therapy), and effectively working with families and people who support these adolescents (such as attachment-based family therapy). ABSTRACT: Introduction Nurses often work in the community with adolescents who self-harm. There is a lack of qualitative research exploring nurses' experiences of working with adolescents who self-harm. Aim This study aimed to gain an understanding of community nurses' experiences of working with adolescents who self-harm. Method Ten semi-structured interviews were conducted with registered nurses working in Child and Adolescent Mental Health Services (CAMHS) in the United Kingdom (UK). Results Data were analysed using interpretative phenomenological analysis (IPA). Two superordinate themes were identified, each consisting of two subordinate themes: personal and professional conflicts, describing interpersonal and intrapersonal conflicts the nurses experienced working with adolescents who self-harm and the systems around them, and personal and professional development, outlining processes of management of conflicts and development. Discussion Nurses feel conflicted about working with adolescents who self-harm within the context of working with systems surrounding the adolescent. They report positive experiences, which they use to reframe their experiences and feelings of shame as a result of their emotional responses, self-care behaviours and personal and professional boundaries. Implications for Practice Nurses working with adolescents who self-harm would benefit from training, reflective practice and self-care. CAMHS managers should encourage and invest in these areas.
