Desire is Not Enough: A Multi-Component State-Space Conceptualisation of Suicidal Thinking

Contemporary research demonstrates that suicidal thinking is heterogeneous in content, multi-modal in form, and dynamically variable across timescales. Advances in descriptive science have deepened our understanding of suicidal ideation, warranting a reconsideration of how desire-based cognitions are embedded in dominant models within the ideation-to-action framework. Across leading models within this framework, suicide capability is conceptualized as a distinct, acquired moderator that facilitates the transition from ideation to attempt but remains external to the phenomenology of ideation itself. We argue that this architecture is conceptually incomplete. Specifically, we distinguish between trait capability that is an acquired, relatively stable dispositional readiness, and state-perceived capability, defined as an episodic, context-sensitive appraisal of feasibility that can emerge during episodes of suicidal thinking. We further propose that when individuals report cognitions such as "I could actually do this," these appraisals of feasibility may become integrated into the phenomenology of some suicidal ideation episodes rather than operating as background moderators. Thus, indicating that capability-referent content may be phenomenologically embedded within suicidal thinking rather than independent from it. Such content is more consistent with dynamic fluctuations in state-perceived capability occurring within ideation episodes than with the operation of a stable, dispositional capability construct. We propose reconceptualising suicidal ideation as a multi-component state space comprising motivational content, suicidal imagery, temporal horizon, and state-perceived capability. This reframing has implications for measurement, risk modeling, and clinical practice, particularly in identifying action-proximal episodes that conventional risk severity metrics may fail to detect.
