Suicide capability is a multidimensional concept that facilitates the movement from suicidal ideation to suicide attempt. The three-step theory of suicide posits that three overarching contributors comprise suicide capability: acquired (fearlessness about death and high pain tolerance), dispositional (genetics), and practical (knowledge and access to lethal means) capability. Although extensive research has investigated relationships between individual contributors of capability and suicide attempts, little research has considered how an individual’s capability for suicide develops as a combination of contributors. Given suicide is multifaceted and complex, our understanding of capability development is relatively limited. This potentially negatively impacts prevention and capacity reduction–focused intervention efficacy. Therefore, this study aimed to explore how suicide capability develops. Fourteen community-based suicide attempt survivors were recruited using convenience sampling. Individual narratives were collected using open-ended interviews, and data were analysed using narrative analysis. Results indicated that participant narratives contained two elements. The first included how capability development and suicide attempt facilitation were often underpinned by the relational interplay between acquired and practical contributors. For example, participants without a high pain tolerance seeking attempt methods that were perceived to be painless. The second element contained a novel finding relating to the agentic role of participants when deciding and attempting suicide. Agency was revealed within and across narratives emphasising the active role the individual plays in their movement from ideation-to-action. The role of individual agency in coming to a decision to take one’s own life and then acting warrants further consideration within contemporary suicide theories.

Background The integrated motivational-volitional model (IMV) is one of the leading theoretical models of suicidal thoughts and behavior. There has been a recent proliferation in the assessment of suicidal and nonsuicidal self-harm thoughts and behaviors (SHTBs) in daily life. Objective This systematic review synthesized evidence from ecological momentary assessment (EMA) studies in the SHTB literature to address the following questions: (1) Which constructs in the IMV model have been assessed using EMA, and how have they been assessed? (2) Do different constructs from the IMV model fluctuate in daily life? (3) What is the relationship between the different IMV constructs and SHTBs in daily life? Methods Consistent with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we conducted systematic searches of 5 databases—Web of Science, Embase, MEDLINE, PsycINFO, and Europe PMC Preprints—from inception to March 26, 2024. Results Our searches resulted in the inclusion and narrative synthesis of 53 studies across 58 papers. A total of 15 IMV constructs were measured using EMA across the included papers. The most frequently measured constructs were thwarted belongingness (24/58, 41% of the papers), future thinking (20/58, 34% of the papers), and perceived burdensomeness (16/58, 28% of the papers). The least frequently measured constructs were humiliation, social problem-solving, mental imagery, and perceived capability for suicide. None of the included papers measured memory biases, goals, norms, or resilience using EMA. Comparison of intraclass correlation coefficients (45/58, 78% of the papers) revealed moderate but inconsistent within-person variance across all the examined constructs. We found evidence (39/58, 67% of the papers) of concurrent associations between almost all constructs and SHTBs in daily life, with some evidence that entrapment, shame, rumination, thwarted belongingness, hopelessness, social support, and impulsivity are additionally associated with SHTBs in lagged (ie, longitudinal) relationships. Conclusions Comparisons were hindered by variation in methodology, including the populations studied, EMA sampling scheme, operationalization of IMV constructs and SHTBs, and statistical approach used. Our findings suggest that EMA studies are a useful methodology for examining risk factors for SHTBs; however, more research is needed for some IMV constructs. Quality assessment suggested several areas for improvement in the reporting of EMA studies in this field.

BACKGROUND The Integrated Motivational-Volitional (IMV) model is one of the leading theoretical models of suicidal thoughts and behaviour. There has been a recent proliferation in the assessment of suicidal and non-suicidal self-harm thoughts and behaviours (SHTBs) in daily life. OBJECTIVE This systematic review synthesises evidence from ecological momentary assessment (EMA) studies to address the following questions: i) Which constructs within the IMV model have been assessed using EMA, and how have they been assessed? ii) Do different constructs from the IMV model fluctuate in daily life? iii) What is the relationship between the different IMV constructs and SHTBs in daily life? METHODS Consistent with PRISMA guidelines, we conducted systematic searches of five databases – Web of Science, Embase, MEDLINE, PsycInfo, and Europe PMC Preprints – from inception to 26th March 2024. RESULTS Our searches resulted in the inclusion and narrative synthesis of 53 studies across 58 papers. Fifteen IMV constructs were measured using EMA across included papers. The most frequently measured constructs were thwarted belongingness (24 studies), future thinking (20 studies) and perceived burdensomeness (16 studies). The least frequently measured were humiliation, social problem-solving, mental imagery, and perceived capability for suicide. None of the included papers measured memory biases, goals, norms, or resilience using EMA. Comparison of intra-class coefficients (45 studies) revealed inconsistency in, but at least moderate, within-person variance across all examined constructs. We found evidence (39 studies) of concurrent associations between almost all constructs and SHTBs in daily life, with some evidence that entrapment, shame, rumination, thwarted belongingness, hopelessness, social support and impulsivity are additionally associated with SHTBs in lagged (i.e. longitudinal) relationships. CONCLUSIONS Comparisons were hindered by variation in methodology, including populations studied, EMA sampling scheme, operationalisation of IMV constructs and SHTBs, and statistical approach used. Our findings suggest that EMA studies are a useful methodology for examining risk factors for SHTB, however more research is needed for some IMV constructs. Quality assessment suggested several areas for how reporting EMA studies in this field might be improved.
