A Qualitative Exploration of the Experiences and Perceptions of Interpersonal Relationships Prior to Attempting Suicide in Young Adults.

ABSTRACT: 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.

Project description:Suicide accounts for nearly 800,000 deaths per year worldwide with rates of both deaths and attempts rising. Family studies have estimated substantial heritability of suicidal behavior; however, collecting the sample sizes necessary for successful genetic studies has remained a challenge. We utilized two different approaches in independent datasets to characterize the contribution of common genetic variation to suicide attempt. The first is a patient reported suicide attempt phenotype asked as part of an online mental health survey taken by a subset of participants (n = 157,366) in the UK Biobank. After quality control, we leveraged a genotyped set of unrelated, white British ancestry participants including 2433 cases and 334,766 controls that included those that did not participate in the survey or were not explicitly asked about attempting suicide. The second leveraged electronic health record (EHR) data from the Vanderbilt University Medical Center (VUMC, 2.8 million patients, 3250 cases) and machine learning to derive probabilities of attempting suicide in 24,546 genotyped patients. We identified significant and comparable heritability estimates of suicide attempt from both the patient reported phenotype in the UK Biobank (h2SNP = 0.035, p = 7.12 × 10-4) and the clinically predicted phenotype from VUMC (h2SNP = 0.046, p = 1.51 × 10-2). A significant genetic overlap was demonstrated between the two measures of suicide attempt in these independent samples through polygenic risk score analysis (t = 4.02, p = 5.75 × 10-5) and genetic correlation (rg = 1.073, SE = 0.36, p = 0.003). Finally, we show significant but incomplete genetic correlation of suicide attempt with insomnia (rg = 0.34-0.81) as well as several psychiatric disorders (rg = 0.26-0.79). This work demonstrates the contribution of common genetic variation to suicide attempt. It points to a genetic underpinning to clinically predicted risk of attempting suicide that is similar to the genetic profile from a patient reported outcome. Lastly, it presents an approach for using EHR data and clinical prediction to generate quantitative measures from binary phenotypes that can improve power for genetic studies.
