Abstract

The Coherence Profile (CP-100) is a 100‑item multi‑domain instrument measuring regulatory stability across physiological, cognitive, behavioral, relational, and environmental domains. While valuable for research, its length limits deployment in clinical intake, workplace screening, longitudinal tracking, and ecological momentary assessment (EMA). This paper presents a proposed development framework for the CP-25, a 25‑item short form (5 items per domain) derived from CP-100 item reduction. The paper describes proposed item reduction methodology, hypothetical factor loading targets, and desired validation statistics (convergent validity r > 0.90, internal consistency α > 0.80, ROC AUC > 0.95). This is a validation protocol and hypothetical framework only. The CP-25 has not yet undergone empirical validation. Proposed cutoffs for low, moderate, and high coherence are offered as provisional screening targets pending normative data collection.

Status Note: All statistics in this paper are hypothetical validation targets for future empirical studies. No actual data collection has occurred.

1. Introduction

StatusThis paper describes a proposed validation framework. All statistics are hypothetical targets for future empirical validation. No actual data collection has been completed. The CP-25 is not yet a validated instrument.

2. Proposed Item Reduction Strategy

2.1 CP-100 Item Pool (unchanged)

2.2 Proposed Item Reduction Strategy

StepMethodHypothetical Target
1Factor loadings from CP-100 validation sample (N = 500 planned)Select 10 highest‑loading items per domain (loading > 0.70)
2Item‑total correlationsEliminate items with r < 0.50
3Content representativenessEnsure each domain retains state and trait balance
4Collinearity checkEliminate redundant items (r > 0.85)
5Expert reviewFinal selection of 5 items per domain

3. Hypothetical CP-25 Item Set

StatusThe following items are proposed based on CP-100 content analysis. Empirical validation (factor loadings, item‑total correlations) is required.

4. Planned Validation Sample (Proposed)

CharacteristicTarget Percentage
Female50‑55%
Male45‑50%
Age range18‑75
Clinical (high stress)25‑35%
Coherence practitioners15‑25%

Planned N: 500 for factor analysis; 300 for convergent validation.

Note: This sample has not yet been recruited. These are design targets.


5. Hypothetical Validation Statistics

The following are target thresholds for future empirical validation, not completed results.

MeasureHypothetical TargetDesired Threshold
Pearson correlation (CP-25 vs. CP-100)r > 0.90> 0.90
Cronbach’s α (total)α > 0.90> 0.85
Cronbach’s α per domainα > 0.80> 0.80
ROC AUC (high vs. low coherence)AUC > 0.95> 0.95
Sensitivity (detecting low coherence)> 85%> 85%
Specificity (detecting high coherence)> 85%> 85%

Note: These are hypothetical values. Empirical validation will determine actual performance.


6. Proposed Scoring and Interpretation

StatusThe following interpretive bands are provisional and require normative data for validation.

7. Proposed Applications (Contingent on Validation)

“If validated, the CP-25 may be suitable for:”


8. Planned Validation Studies

StudyDescriptionStatus
1Factor analysis (N = 500)Planned
2Convergent validity with HRV (N = 100)Planned
3Test‑retest reliability (2 weeks, N = 100)Planned
4Known‑groups validity (coherence practitioners vs. burnout) (N = 100 per group)Planned
5EMA validation (14 days, N = 50)Planned

9. Limitations

LimitationMitigation
No empirical validation has been conductedThis is a proposed framework; validation studies are required
Item selection is hypotheticalActual factor loadings may differ
Cutoffs are provisionalNormative data needed
Not yet suitable for clinical useValidation required before deployment

10. Conclusion

This paper has presented a proposed development and validation framework for the CP-25, a brief multi‑domain coherence screening instrument. Hypothetical item sets, scoring algorithms, and validation targets have been described. The CP-25 has not yet undergone empirical validation. Future work will recruit validation samples, conduct factor analysis, establish psychometric properties, and determine normative cutoffs. Until then, the CP-25 is a research framework, not a deployable instrument.
