The suicidality differentiation model, developed and clinically evaluated by de Winter and colleagues, organizes suicidality around the concept of entrapment, defined as a person’s subjective perception of being caught in uncontrollable, unremitting and inescapable circumstances. The model identifies four categories of entrapment that give rise to suicidal states: perceptual disintegration, primary depressive cognition, psychosocial turmoil and inadequate coping. Unlike contemporary evidence-based frameworks such as the Integrated Motivational-Volitional Model, the Interpersonal Theory of Suicide, the Ideation-to-Action Framework, the Three-Step Theory and the Narrative-Crisis Model, which explain mechanisms underlying suicidality, the differentiation model is specifically designed to distinguish between distinct subtypes in clinical practice.

Each subtype carries a distinct clinical signature. Perceptual disintegration describes suicidality rooted primarily in psychosis, typically of short duration, in which distress may be understandable but its severity and suffering are no longer perceived as comprehensible by the examiner; a classic case is suicidality during a depression with mood-congruent psychotic features, or psychotic states in which delusions and hallucinations command self-harm. Primary depressive cognition stems from a depressive thought process without psychotic features, often persisting for weeks or months, with daily suicidal thoughts that may also arise in anxiety disorders, autism spectrum disorder or existential states without meeting criteria for a depressive disorder, and in which Beck’s cognitive triad of negative views about oneself, the world and the future may be present.

Psychosocial turmoil, by contrast, follows a severe loss or blow to the ego that upends a person’s life, producing enormous guilt, severe shame, fear of eye contact or despair without psychosis, with unbearable anguish lasting hours, days or weeks; substance abuse can amplify its expression, and underlying impulsivity dysregulation raises the risk of a lethal outcome. Inadequate coping describes severe distress that the person cannot properly communicate, in which suicidality is demonstrated in the hope of a solution; this chronic, severely fluctuating pattern, often seen in borderline personality disorder, can be perceived by others as externalizing and inauthentic, exhausting support systems, yet the person is genuinely in distress, and suicide may become the ultimate way to communicate perceived unfairness or rejection.

To compare this model with the historical typologies, the authors adapted the concept-analysis method of Walker and Avant into three phases. First, a researcher labelled and extracted the fundamental concepts of each typology through targeted content analysis. Second, two researchers collaboratively defined those concepts through conceptual mapping, interpreting their attributes and boundaries. Third, the same two researchers compared, related and aligned the definitions through deliberative synthesis, iteratively reaching agreement on the relative conceptual positioning of the typologies. The authors emphasize that the resulting associations are exploratory and interpretive rather than deterministic, established across different levels of analysis and scientific domains, and that multiple concepts can be linked to a single subtype when they reflect the same underlying mechanisms.

The comparison yields a dense web of correspondences. Perceptual disintegration may overlap with Menninger’s wish to die, with Henderson and Williams’s depressive, alienation, avoidance and modelling behaviours, with Shneidman’s classifications of death seekers or death ignorers, and with Freud’s intentional suicide, Mintz’s symptomatic and adaptational acts, Baechler’s escapist and oblative suicides, Shneidman’s egotic and ageneratic suicides, and Durkheim’s egoistic suicide. Primary depressive cognition overlaps with the wish to die, with depressive, avoidance and modelling behaviours, with death seekers or death initiators, and with intentional, symptomatic, adaptational, escapist, oblative, egotic, altruistic and fatalistic suicide.

Psychosocial turmoil aligns with Menninger’s wish to be killed, with modelling and avoidance behaviours, with Shneidman’s death darers, and with Freud’s semi-intentional suicide, Mintz’s adaptational acts, Leonard’s satisfied-symbiotic and unaccepting suicides, and Durkheim’s anomic suicide. Inadequate coping corresponds to the wish to kill, to extrapunitive, operant and modelling behaviours, to death darers, and to semi-intentional, communicative and adaptational acts, Baechler’s aggressive suicide, Leonard’s dependent-dissatisfied suicide and Shneidman’s dyadic suicide. Some classic categories resist mapping altogether: Baechler’s ludic suicides, in which people die engaging in risky activities to fully experience life, show no clear overlap, because in the model’s subtypes risky behaviour is a byproduct of a mental state rather than a conscious pursuit of experience.

The comparison also exposes blind spots. Leonard’s typology, grounded in the degree of independence from and differentiation of the parental figure in early childhood, only partially corresponds to the model, revealing a notable lacuna concerning formative child-parent dynamics within its subtypes. Shneidman’s typologies likewise align only partially, because the differentiation model omits both the individual’s physical health status and spiritual beliefs about death and suicide, reflecting a somewhat unilateral emphasis on the psychological dimension. The authors argue that further scholarly exploration of the interplay between the corporeal and psychological domains, and of the metaphysical perspectives underpinning each subtype, is warranted. Notably, inadequate coping showed the least obvious overlap with concepts from the other typologies, consistent with prior work identifying it as the most ambiguously delineated subtype; the authors suggest each subtype may in fact be a distinct expression of maladaptive coping, and that suicidality itself may constitute an overarching manifestation of coping failure, underscoring the need for a more finely grained and operationally precise delineation.

The authors acknowledge important limitations. The typologies examined carry a predominantly Eurocentric orientation, which may circumscribe appreciation of their historical evolution and culturally situated meanings. The comparison’s clinical and diagnostic scope may constrain consideration of how developmental and lifespan events, and physical, psychological and social comorbidities, shape suicidality. Because the juxtaposed typologies were developed from different theoretical perspectives, the identified correspondences should be read as partial conceptual overlaps rather than direct equivalences. And because the mapping procedure lacked independent coding or formal inter-rater assessment, interpretive or confirmation bias may have crept in. The principal strength, the authors argue, lies in integratively reconciling sociological, behavioural, relational, psychological and psychoanalytic perspectives on suicidality.

The team concludes that refining the model by clarifying formative developmental dynamics, corporeal-psychological interplay and metaphysical perspectives, and by sharpening the distinctions between subtypes, could enhance its value for mental healthcare organizations, professionals and patients. Future research, they write, should examine whether the refined model supports more precise clinical assessment, including its potential to improve risk identification, care personalization, diagnostic accuracy and treatment efficacy, and whether it offers a more detailed and practical framework for structuring suicide prevention services, including improved organizational processes and resource allocation. For now, the comparison positions the young model within a century-old intellectual lineage while marking exactly where that lineage can still teach it something new.
