As the body of research on suicide in later life has developed, so has its vocabulary. This has generated a high level of overlap in concepts and terminology used to articulate suicide and how it might present, as well as ‘grey area’ behavioural terms that are both specific to older adults and less well-defined (e.g. ‘hastening of death’ or ‘completed life’). A better understanding of individual experiences and pathways to suicide can help to inform assessment and interventions, and increase the potential to relate any theoretical concepts to the implementation of such. Here, we adopted a scoping review to search systematically literature on specific presentation, features, circumstances and outcomes of these grey areas of suicide in later life. Fifty-three articles (quantitative, qualitative and theoretical) were reviewed. A narrative approach was used to merge and translate this body of knowledge into a new conceptual framework based on four key themes: (a) a sense of completed life or existential loneliness; (b) death thoughts, wishes and ideation; (c) death-hastening behaviour and advanced directives; and (d) self-destructive or self-injurious behaviour. We discuss the importance of integrating this understanding into current knowledge and suicide prevention strategies for older adults. Recommendations are made for unifying research with policy themes on healthy ageing, person-centredness within service provision and citizen participation.

Objectives: Rates of suicide in older adults may be higher than reported due to poor understandings of presentation of suicide ideation in this group. The objectives of this paper were to (i) review current measurement tools designed for older adults to detect suicide ideation and (ii) assess their psychometric properties. Design: We used a systematic review approach to identify measurement tools developed specifically for older adults without cognitive decline or impairment. Results: Ten articles that reported on a total of seven different measurement tools were identified. These included tools that focused on resiliency to suicide and those that measured risk of suicide behavior. There was wide variation across the articles: some were adaptations of existing scales to suit older populations, others were developed by authors; they varied in length from four to 69 items; a range of settings was used, and there was a mix of self-report and clinician-administered measures. Most displayed good psychometric properties, with both approaches showing similar quality. Limitations in terms of samples, settings, and measurement design are discussed. Conclusion: The case for specific measures for older adults is clear from this review. There appear to be unique factors that should be considered in understanding suicide ideation and behavior among older adults that may not be directly assessed in non-specific measurements. However, there is a need to expand the diversity of individuals included in measurement development to ensure they are appropriate across gender, culture and minority status, and for the views of professionals to be considered.
