Introduction

Seven recent studies push the measurement of existential constructs forward. A new Self–World Existential Isolation Scale captures the felt rift between inner experience and shared reality, the Existential Quest Scale gets a rigorous IRT validation, and a dedicated Occupational Meaning in Life Questionnaire extends meaning research into the workplace. Alongside these, cross-cultural and clinical adaptations of the MLQ — for Chinese adolescents and for borderline personality disorder — test whether established tools hold up in new populations. Two veteran-focused studies round out the picture, linking existential isolation to trauma, reintegration, and well-being.

The Associations Among Existential Isolation, Shared Reality, and Veterans’ Health

Karla Fuentes Maldonado · 2025

At a GlanceAI

Shared reality in close relationships predicts less existential isolation and better veteran mental and physical health, beyond loneliness.

SummaryAI

The study highlights existential isolation—feeling fundamentally misunderstood—as a distinct risk factor for veterans’ distress and poorer health. In a survey of 464 U.S. veterans, greater generalized shared reality in close relationships was linked to lower existential isolation and better outcomes, including less depression and better physical well-being. Mediation analyses suggest existential isolation partly explains how shared reality relates to depression and physical health even when accounting for loneliness. The findings point to shared-reality-building relationship and reintegration supports as promising intervention targets for veteran well-being.

Method:AI
Cross-sectional survey of U.S. veterans using self-report measures with mediation analyses controlling for loneliness.
Background:AI
Basic knowledge of existential isolation, loneliness/social connection, and common mental health outcomes in veterans (PTSD, depression, anxiety).

The occupational meaning in life questionnaire: development, reliability, and validity

Jun Cai, Xinqiang Wang, Shinong Pan · 2025

At a GlanceAI

Introduces and validates a questionnaire to assess how people find meaning in life through their occupational roles and work life.

SummaryAI

The authors develop the Occupational Meaning in Life Questionnaire and report evidence for its reliability and validity. The work is important because it offers a work-focused tool for studying a core existential construct—meaning in life—within occupational settings. By operationalizing “meaning in life” specifically in relation to one’s occupation, it supports research and practice on how work contributes to existential fulfillment and well-being.

Method:AI
Scale development and psychometric validation of a new questionnaire (reliability and validity testing).
Background:AI
Basic existential psychology of meaning in life plus familiarity with psychological measurement and psychometrics.

Propiedades psicométricas del Meaning in Life Questionnaire en personas diagnosticadas con Trastorno Límite de la Personalidad(pdf)

Joaquín García‐Alandete, Sandra Pérez, Fátima Lorca-Alamar et al. · 2025

At a GlanceAI

Validates the MLQ’s Presence/Search structure and reliability for assessing meaning in life in people with borderline personality disorder.

SummaryAI

The study tests whether the Meaning in Life Questionnaire (MLQ) works well in a clinical group diagnosed with borderline personality disorder (BPD). In a Spanish sample, the MLQ’s two-factor structure (Presence and Search) showed strong model fit and adequate internal consistency, supporting its use with BPD patients. Presence of Meaning related positively to purpose in life and negatively to dissociative experiences, linking existential meaning to clinically relevant outcomes. These results support incorporating meaning-focused assessment and interventions to reduce existential distress and support coping in BPD treatment.

Method:AI
Psychometric validation using self-report scales with factor-model testing and correlational analyses in a clinical BPD sample.
Background:AI
Basic knowledge of existential psychology (meaning/purpose) and fundamentals of psychological measurement (reliability, factor structure, validity).

Meaning in Life Questionnaire: Validation for Chinese Adolescents(pdf)

Xiang Zhao, Gareth Davey, Xiangxing Wan · 2025

At a GlanceAI

Validates the Meaning in Life Questionnaire for Chinese adolescents, confirming its two-factor structure but flagging issues in two items.

SummaryAI

The study strengthens evidence that the Meaning in Life Questionnaire (MLQ) can be used to assess meaning in life among Chinese adolescents, a group with previously limited methodological validation. Using a large, provincially representative school sample, it confirms the MLQ’s two-factor structure (Presence and Search) and supports overall reliability. At the same time, item-level response patterns raise concerns about the final two items, implying they may function differently and merit closer scrutiny (e.g., subgroup-specific interpretation). The findings support broader research and clinical use of the MLQ in Chinese youth while highlighting where measurement refinement may be needed.

Method:AI
Psychometric validation using confirmatory factor analysis and reliability/item-level analyses in a large adolescent school sample.
Background:AI
Basic psychometrics (factor structure, reliability) and existential psychology concepts around meaning in life (Presence vs Search).

Trauma, existential isolation, and their associated clinical outcomes

Tatum Loso, Rachel M. Gehman, Elizabeth C. Pinel et al. · 2025

At a GlanceAI

Across two large samples, existential isolation links cumulative trauma exposure to distress and suicidal ideation beyond loneliness.

SummaryAI

Across two studies, the authors test whether cumulative trauma is associated with existential isolation—feeling alone in one’s experience of reality—and whether this helps explain later psychological distress. In both undergraduate and adult samples, more trauma exposure related to higher existential isolation even when controlling for loneliness. Existential isolation statistically mediated the association between trauma and depression, anxiety, stress, and suicidal ideation, and this held for both interpersonal and non-interpersonal traumas. The work positions existential isolation as a clinically relevant target for trauma-focused assessment and intervention, not just social disconnection.

Validating the Existential Quest Scale using item response theory(pdf)

Marco Rizzo, Giorgia Molinengo, Barbara Loera et al. · 2026

At a GlanceAI

Rasch IRT validation shows the Existential Quest Scale is unidimensional, invariant across groups, and offers item-level guidance for improvement.

SummaryAI

The study strengthens measurement of “existential quest”—openness to engaging existential questions in religious or secular contexts—by moving beyond classical test theory to item response theory. Using Rasch modeling in a large heterogeneous sample, it finds the EQS is unidimensional, discriminates levels of existential quest, and is measurement-invariant across sex, age, and religious affiliation, supporting fair comparison across groups. The analyses also flag specific item/response category issues and propose revisions, improving the tool’s precision for research on psychological flexibility, identity development, and social attitudes in multicultural settings.

Method:AI
Rasch (item response theory) modeling was used to test dimensionality, item functioning, and measurement invariance in a large survey sample.
Background:AI
Basic psychometrics (reliability/validity) plus familiarity with existential concerns and questionnaire measurement (CTT vs IRT/Rasch).

Sensing a rift in reality: Validation of the self-world existential isolation scale

Roger Young, Kenneth E. Vail, Peter Helm et al. · 2026

At a GlanceAI

Validates a scale measuring self–world existential isolation, capturing a perceived rift between one’s inner experience and shared reality.

SummaryAI

The paper introduces and validates the Self–World Existential Isolation Scale, aimed at assessing the feeling that one’s subjective experience is fundamentally disconnected from others and the broader world. By operationalizing this “rift in reality,” it helps distinguish existential isolation from more familiar forms of social isolation or loneliness. The scale offers researchers a dedicated tool to study how this specifically existential disconnection relates to well-being and other psychological outcomes. It also supports clearer measurement in existential psychology by refining how existential isolation is defined and quantified.

Existential Isolation as a Barrier to Veteran Employment Satisfaction: Implications for Workplace Reintegration

CALEB BLANCHARD · 2026

At a GlanceAI

Longitudinal test of whether workplace “I-sharing” reduces veterans’ existential isolation and improves well-being and job satisfaction.

SummaryAI

Veterans often feel misunderstood in civilian workplaces, and the abstract frames this as existential isolation—feeling that others do not share or grasp one’s lived experience. The study proposes a practical reintegration lever: prompting veterans to reflect weekly on “I-sharing” moments with coworkers to reduce existential isolation. By tracking mental well-being and workplace satisfaction over six weeks plus 3- and 6-month follow-ups, it aims to show whether changing day-to-day subjective connection at work can improve longer-term adjustment. If supported, the work suggests workplace-based, low-cost interventions could target an existential barrier that undermines both personal and professional relationships.

I-Sharing, not exactly existential isolation
