Suicide is a leading public health concern. Research studies have identified significant associations between loneliness and suicidal ideation/behaviour both cross-sectionally and prospectively. Despite this, research specifically focusing on identifying the nature of loneliness experienced prior to suicide, and the role it has in association with other preceding factors, has not been fully explored. The current study recruited ten participants with a history of suicide attempts (five female, four male and one non-binary; mean age: 22.5, range: 20–25 years) to take part in one-to-one, semi-structured interviews via remote video conferencing to explore experiences of social support and loneliness prior to suicide attempt. Using Interpretative Phenomenological Analysis, several aspects of loneliness emerged as important themes that were present prior to participants’ suicide attempts. Additional themes identified were patterns of social support, personality traits, emotional secrecy and social transition. Evidence suggests that a positive relationship with parents, knowing someone with similar experiences or having membership in more than one friendship group may reduce feelings of loneliness and/or intentions to die. This research makes an important contribution to understanding the role of loneliness in relation to suicide attempts by highlighting the importance of social supports being emotionally available to those experiencing distress.
