Abstract
The coherence construct, as operationalized in the Coherence Metrics Framework (Humble, 2026), spans physiological, cognitive, behavioral, relational, and environmental domains. This breadth raises a critical question: Is coherence a distinct construct, or does it merely repackage existing psychological and physiological constructs such as resilience, self‑regulation, executive functioning, well‑being, and vagal tone? This paper addresses that question by proposing a construct differentiation framework. For each adjacent construct, the paper proposes: (1) definitional overlap with coherence, (2) theoretical differentiation, (3) convergent validity hypotheses (expected correlations), and (4) discriminant validity hypotheses (expected distinctions). A nomological network is proposed. The paper is offered as a research agenda for future empirical validation.
Keywords: coherence, construct differentiation, discriminant validity, convergent validity, resilience, self‑regulation, executive functioning, well‑being, vagal tone
1. Introduction
The coherence construct, as defined in the Coherence Metrics Framework (Humble, 2026), is multi‑domain: physiological, cognitive, behavioral, relational, and environmental. This breadth is a strength — but also a risk. Without clear differentiation from established constructs, coherence may be dismissed as:
- A relabeling of resilience
- A repackaging of self‑regulation
- An umbrella term for executive functioning
- A proxy for well‑being
- A physiological index (HRV/vagal tone) with unnecessary additional domains
This paper addresses that risk. It proposes a construct differentiation framework, articulating how coherence is theoretically distinct from adjacent constructs while acknowledging overlap. Convergent and discriminant validity hypotheses are presented. A nomological network is proposed for future empirical testing.
Status Note: This is a proposed framework. No empirical validation has been conducted.
2. Coherence: Core Definition
For reference, coherence is defined in this framework as:
The degree of alignment, integration, and stability within and across physiological, cognitive, behavioral, relational, and environmental systems.
Key features distinguishing coherence from other constructs:
| Feature | Description |
|---|---|
| Multi‑domain | Spans physiology, cognition, behavior, relationships, environment |
| Systems integration | Emphasizes cross‑domain alignment, not just single‑domain capacity |
| Dynamic stability | Focuses on return to baseline after perturbation |
| Environmental embeddedness | Explicitly includes environmental/institutional domain |
| Measurable | Operationalized via CP-100, CP-25, HRV, behavioral logs |
3. Adjacent Constructs for Differentiation
| Construct | Definition | Source |
|---|---|---|
| Resilience | Capacity to recover from adversity; “bouncing back” | Masten, 2001; Luthar, Cicchetti, & Becker, 2000 |
| Self‑regulation | Ability to control thoughts, emotions, and behaviors | Baumeister & Vohs, 2004; Karoly, 1993 |
| Executive functioning | Cognitive processes (inhibition, working memory, cognitive flexibility) | Miyake et al., 2000; Diamond, 2013 |
| Well‑being | Subjective quality of life; happiness, life satisfaction | Diener, 1984; Ryff, 1989 |
| Vagal tone (HRV) | Physiological index of parasympathetic activity | Thayer & Lane, 2000; Porges, 2011 |
4. Differentiation from Resilience
4.1 Definitional Overlap
| Shared Feature | Description |
|---|---|
| Stress recovery | Both involve return to baseline after challenge |
| Adaptation | Both involve capacity to adapt to adverse conditions |
| Protection | Both are associated with better outcomes under stress |
4.2 Theoretical Differentiation
| Dimension | Resilience | Coherence |
|---|---|---|
| Primary focus | Recovery from adversity | Multi‑domain alignment and stability |
| Domains | Often single‑domain (psychological) | Explicitly multi‑domain (physiological, cognitive, behavioral, relational, environmental) |
| Environmental role | Contextual factor (support, resources) | Core domain (environmental coherence measured directly) |
| Stability emphasis | Recovery (temporal) | Alignment (cross‑domain integration) |
| Measurement | Often self‑report (e.g., CD‑RISC) | Multi‑method (self‑report, HRV, behavioral logs, environmental assessment) |
Proposed distinction: Resilience is recovery; coherence is integrated stability. A person can be resilient (recovers quickly) but still have low coherence (domains misaligned). Conversely, a person can have high coherence (domains aligned) but low resilience (slow recovery).
4.3 Proposed Convergent and Divergent Validity
| Relationship | Expected Correlation (r) | Rationale |
|---|---|---|
| Coherence with resilience (e.g., CD‑RISC) | r = 0.50‑0.65 | Moderate overlap; both involve stress response |
| Coherence with resilience, controlling for environmental domain | r = 0.40‑0.55 | Coherence includes environment; resilience does not |
| Resilience predicts coherence beyond shared variance | Partial (β = 0.20‑0.35) | Resilience contributes to coherence but does not define it |
5. Differentiation from Self‑Regulation
5.1 Definitional Overlap
| Shared Feature | Description |
|---|---|
| Behavioral control | Both involve capacity to regulate behavior |
| Emotional regulation | Both involve managing emotional responses |
| Goal pursuit | Both support intentional action |
5.2 Theoretical Differentiation
| Dimension | Self‑Regulation | Coherence |
|---|---|---|
| Primary focus | Control of impulses and behavior | Alignment across multiple domains |
| Domains | Primarily behavioral/cognitive | Explicitly includes physiological, relational, environmental |
| Environmental role | Not typically measured | Core domain (environmental coherence) |
| Emphasis | Internal control | System integration |
| Measurement | Often task‑based (e.g., Stroop, go/no‑go) | Multi‑method, including physiological and environmental |
Proposed distinction: Self‑regulation is control; coherence is alignment. A person can have high self‑regulation (controls impulses) but low coherence (physiological dysregulation, chaotic environment). Conversely, a person can have high coherence (domains aligned) but low self‑regulation (poor impulse control) — though this is less likely, as coherence may support self‑regulation.
5.3 Proposed Convergent and Divergent Validity
| Relationship | Expected Correlation (r) | Rationale |
|---|---|---|
| Coherence with self‑regulation (e.g., SRSI) | r = 0.55‑0.70 | Substantial overlap; coherence includes regulatory capacity |
| Coherence with self‑regulation, controlling for physiological domain | r = 0.40‑0.55 | Coherence includes non‑cognitive domains |
| Self‑regulation predicts coherence beyond shared variance | Partial (β = 0.25‑0.40) | Self‑regulation contributes but is not identical |
6. Differentiation from Executive Functioning
6.1 Definitional Overlap
| Shared Feature | Description |
|---|---|
| Attentional control | Both involve sustained attention and inhibition |
| Cognitive flexibility | Both involve adapting to changing demands |
| Working memory | Both involve maintaining information online |
6.2 Theoretical Differentiation
| Dimension | Executive Functioning | Coherence |
|---|---|---|
| Primary focus | Cognitive processes (inhibition, working memory, shifting) | Multi‑domain alignment |
| Domains | Purely cognitive | Physiological, behavioral, relational, environmental |
| Measurement | Performance‑based tasks (e.g., Wisconsin Card Sort, Stroop) | Self‑report, behavioral logs, physiological, environmental |
| Emphasis | Cognitive efficiency | Cross‑domain integration |
| Environmental role | Not measured | Core domain |
Proposed distinction: Executive functioning is cognitive capacity; coherence is systems integration. A person can have high executive functioning (good cognitive control) but low coherence (physiological dysregulation, relational conflict). Executive functioning may be a component of coherence’s cognitive domain but does not define the full construct.
6.3 Proposed Convergent and Divergent Validity
| Relationship | Expected Correlation (r) | Rationale |
|---|---|---|
| Coherence with executive functioning (e.g., BRIEF‑A) | r = 0.40‑0.55 | Moderate overlap; coherence includes non‑cognitive domains |
| Coherence with executive functioning, controlling for cognitive domain | r = 0.20‑0.35 | Coherence’s cognitive domain overlaps with executive functioning |
| Cognitive coherence domain with executive functioning | r = 0.55‑0.70 | The cognitive domain is conceptually closest to executive functioning |
7. Differentiation from Well‑Being
7.1 Definitional Overlap
| Shared Feature | Description |
|---|---|
| Subjective experience | Both involve how individuals feel about their lives |
| Functioning | Both are associated with adaptive functioning |
| Quality of life | Both predict life satisfaction and flourishing |
7.2 Theoretical Differentiation
| Dimension | Well‑Being | Coherence |
|---|---|---|
| Primary focus | Subjective quality of life; happiness | Objective regulatory stability |
| Domains | Hedonic (pleasure) and eudaimonic (meaning) | Physiological, cognitive, behavioral, relational, environmental |
| Emphasis | Subjective experience | Measurable system properties (HRV, attention logs, behavioral consistency) |
| Environmental role | Contextual factor | Core domain |
| Causal direction | Coherence may predict well‑being; distinct but related | — |
Proposed distinction: Well‑being is subjective; coherence is objective (measurable). A person can report high well‑being but have low coherence (e.g., manic state, denial of dysfunction). Conversely, a person can have high coherence but moderate well‑being (e.g., stable but not happy).
7.3 Proposed Convergent and Divergent Validity
| Relationship | Expected Correlation (r) | Rationale |
|---|---|---|
| Coherence with well‑being (e.g., WHO‑5, PERMA) | r = 0.50‑0.65 | Moderate to strong overlap; coherence supports well‑being |
| Coherence with well‑being, controlling for self‑report bias | r = 0.35‑0.50 | Coherence includes objective measures; well‑being is purely subjective |
| Well‑being predicts coherence beyond shared variance | Partial (β = 0.20‑0.35) | Well‑being contributes but does not define coherence |
8. Differentiation from Vagal Tone (HRV)
8.1 Definitional Overlap
| Shared Feature | Description |
|---|---|
| Physiological regulation | Both involve autonomic nervous system function |
| Stress response | Both predict recovery from stress |
| Health outcomes | Both associated with cardiovascular and mental health |
8.2 Theoretical Differentiation
| Dimension | Vagal Tone (HRV) | Coherence |
|---|---|---|
| Primary focus | Physiological parasympathetic activity | Multi‑domain alignment |
| Domains | Purely physiological | Physiological, cognitive, behavioral, relational, environmental |
| Measurement | ECG, wearable (RMSSD, HF power) | Multi‑method (self‑report, HRV, behavioral logs, environmental assessment) |
| Emphasis | Bottom‑up physiological capacity | Top‑down and bottom‑up integration |
| Environmental role | Not measured | Core domain |
Proposed distinction: Vagal tone is a physiological indicator; coherence is a multi‑domain construct that includes vagal tone as one component. A person can have high vagal tone (good physiological regulation) but low coherence (relational conflict, environmental chaos). Vagal tone may be the physiological foundation of coherence but is not synonymous with it.
8.3 Proposed Convergent and Divergent Validity
| Relationship | Expected Correlation (r) | Rationale |
|---|---|---|
| Coherence with HRV (RMSSD) | r = 0.30‑0.45 | Moderate overlap; coherence includes non‑physiological domains |
| Physiological coherence domain with HRV | r = 0.55‑0.70 | Strong overlap; this domain is designed to index HRV |
| Coherence with HRV, controlling for physiological domain | r = 0.10‑0.20 | Non‑physiological domains should have minimal direct HRV correlation |
9. Nomological Network (Proposed)
The nomological network positions coherence among related constructs.
| Construct | Relationship to Coherence (Proposed) |
|---|---|
| Resilience | Related but distinct (r = 0.50‑0.65) |
| Self‑regulation | Related but distinct (r = 0.55‑0.70) |
| Executive functioning | Moderately related (r = 0.40‑0.55) |
| Well‑being | Related but distinct (r = 0.50‑0.65) |
| Vagal tone (HRV) | Moderate relationship (r = 0.30‑0.45) |
| Age | Weak negative (r = -0.10 to -0.20) |
| Education | Weak positive (r = 0.10‑0.20) |
| Chronic stress (PSS) | Moderate negative (r = -0.40 to -0.55) |
| Social support | Moderate positive (r = 0.30‑0.45) |
| Environmental coherence (ECI) | Strong positive (r = 0.50‑0.70) |
10. Proposed CFA Structure for Discriminant Validity Testing
A confirmatory factor analysis (CFA) model with the following structure is proposed for future validation:
| Factor | Indicators |
|---|---|
| Coherence | CP-100 domain scores (physiological, cognitive, behavioral, relational, environmental) |
| Resilience | CD‑RISC (Connor‑Davidson Resilience Scale) |
| Self‑regulation | SRSI (Self‑Regulation Scale Inventory) |
| Executive functioning | BRIEF‑A (Behavior Rating Inventory of Executive Function) |
| Well‑being | WHO‑5 or PERMA |
| Vagal tone | RMSSD (wearable HRV) |
Hypothesized model fit: CFI > 0.90, RMSEA < 0.08, with coherence factor showing discriminant validity (correlations with other factors < 0.70, preferably < 0.60).
11. Testable Hypotheses
| Hypothesis | Description | Proposed Analysis |
|---|---|---|
| H1: Coherence vs. resilience | Coherence and resilience correlate (r = 0.50‑0.65) but are distinct | CFA, correlation comparison |
| H2: Coherence vs. self‑regulation | Coherence and self‑regulation correlate (r = 0.55‑0.70) but are distinct | CFA |
| H3: Coherence vs. executive functioning | Coherence and executive functioning correlate (r = 0.40‑0.55) | CFA |
| H4: Coherence vs. well‑being | Coherence and well‑being correlate (r = 0.50‑0.65) | CFA |
| H5: Coherence vs. vagal tone | Coherence physiological domain correlates strongly with HRV (r = 0.55‑0.70); total coherence correlates moderately (r = 0.30‑0.45) | Correlation |
| H6: Incremental validity | Coherence predicts well‑being beyond resilience, self‑regulation, and executive functioning | Hierarchical regression |
| H7: Discriminant validity | Correlations between coherence and adjacent constructs are significantly less than 1.0 (p < 0.01) | χ² difference tests |
12. Planned Validation Studies
| Study | Description | Status |
|---|---|---|
| 1 | Cross‑sectional construct validation (N = 500) | Planned |
| 2 | Multitrait‑multimethod matrix (self‑report + observer + physiological) (N = 200) | Planned |
| 3 | Test‑retest discriminant stability (2 weeks, N = 100) | Planned |
| 4 | Known‑groups: Coherence practitioners vs. general population | Planned |
13. Limitations
| Limitation | Mitigation |
|---|---|
| No empirical validation yet | Proposed framework; validation studies required |
| Circularity risk | Coherence is defined by its domains; validation requires demonstrating that domains cohere and are distinct from other constructs |
| Selection of comparison constructs | Other constructs (e.g., grit, hardiness, emotional regulation) could also be included |
| Method variance | Self‑report overlap may inflate correlations; multi‑method designs needed |
| Cultural specificity | Construct relationships may vary cross‑culturally |
14. Conclusion
This paper has proposed a construct differentiation framework for coherence, distinguishing it from resilience, self‑regulation, executive functioning, well‑being, and vagal tone. Convergent and discriminant validity hypotheses were presented. A nomological network was proposed. Testable hypotheses were offered.
The framework addresses the central risk of construct inflation: without clear differentiation, coherence may be dismissed as a repackaging of existing constructs. Empirical validation is required. If supported, coherence would stand as a distinct construct — multi‑domain, systems‑focused, and environmentally embedded — offering integrative value beyond its component parts.
“Coherence is not resilience, though resilience contributes. Not self‑regulation, though self‑regulation overlaps. Not executive functioning, well‑being, or vagal tone alone. Coherence is the integration of all five.”
