Abstract
SPIRAL is a six-dimensional dimensional framework for layering on top of validated symptom-burden instruments (PHQ-9, GAD-7, OCI-R, PCL-5, etc.). It augments instrument-level scoring with a unified wellbeing-direction composite Index, deficit-aware bar visualization, and a first-class spiritual-cultural axis missing from RDoC, HiTOP, PERMA, and WHO-ICF. SPIRAL is positioned as a culturally-calibrated, lay-readable, open- methodology framework to be released alongside published norms across 8 locales (Arabic, English, French, Spanish, Hindi, Urdu, Chinese, Portuguese).
1. Background
1.1 Existing frameworks for symptom-burden tests
Standard practice presents PHQ-9 / GAD-7 results as a single raw total mapped to band labels (Minimal, Mild, Moderate, Moderately Severe, Severe). Modern dimensional frameworks (RDoC, NIMH 2010; HiTOP, Kotov et al. 2017) offer trans-diagnostic structure but remain research-grade and language-limited (English-first). Zat+'s prior PRISM layer provides five dimensions but lacks cultural and relational axes.
1.2 Identified gaps
- No cultural-spiritual axis in any major framework.
- Limited lay-readability — academic terminology dominates.
- Mixed direction conventions confuse users (some scales higher = worse, others higher = better).
- Single-frame psychopathology focus ignores strengths.
- No epistemic uncertainty displayed (point estimates only).
- Western-derived norms inappropriately applied cross-culturally.
1.3 Why SPIRAL
SPIRAL addresses each gap with a minimal six-dimension model spanning state-level symptom load, temporal pattern, coping resources, social support, daily-function integrity, and meaning. The acronym is mnemonic and the layer is non-replacement: SPIRAL augments existing instrument scoring, never replaces it.
2. Framework Specification
2.1 Dimensions
| Code | Name | Direction | Operationalization (v1.0 SPIRAL-on-PHQ9) |
|---|---|---|---|
| S | Self-meaning | strength | Cultural Formulation Interview-derived, 6 items (planned). v1.0 placeholder = neutral 60. |
| P | Pressure | deficit | Severity proxy from PRISM-S (Severity dimension). |
| I | Imprint | deficit | Daily-frequency ratio: count(items with value=3) / total items × 100. |
| R | Relations | strength | Relational sub-questions (planned). v1.0 placeholder = neutral 60. |
| A | Adaptation | strength | Resilience proxy from PRISM-R. |
| L | Life | strength | Inverse functional Impact: 100 − PRISM-I. |
2.2 Composite Index
Wellbeing-direction (higher = better). Deficit dims inverted internally.
SPIRAL_Index = round(
(100 − P) × 0.16 +
(100 − I) × 0.16 +
S × 0.16 +
R × 0.14 +
A × 0.20 +
L × 0.18
)
Weights are pre-validation; pilot data will refine.
2.3 Tier bands (quartile-based)
- Strength dims: Weak (0–25), Moderate (26–50), Good (51–75), Strong (76–100)
- Deficit dims: Mild (0–25), Moderate (26–50), Marked (51–75), Severe (76–100)
2.4 Norm bands
Per-instrument, derived from validated meta-analyses. PHQ-9 norms cite Negeri et al. 2021 (BMJ, k=44 IPD MA, N=12,231); GAD-7 cite Plummer et al. 2016 (k=12 MA) plus Toussaint et al. 2020.
3. Validation Plan
- Pilot N ≥ 1,500 across 3 locales (ar, en, hi) — completed Q3.
- Confirmatory factor analysis (CFA) — six-factor model fit indices (CFI ≥ 0.95, RMSEA ≤ 0.06).
- Cross-cultural measurement invariance (configural → metric → scalar).
- Convergent validity vs WHO-5 (r ≥ 0.50) and PHQ-9 total (r ≥ 0.55 for Pressure, ≤ 0.30 for Self-meaning — discriminant).
- Test-retest ICC ≥ 0.70 (2-week interval).
- Differential Item Functioning by gender, age, locale.

5. Limitations
- v1.0 places S and R dimensions at neutral 60 until the CFI-Lite cultural-formulation layer ships (planned Q1 next).
- Norms are instrument-level, not yet locale-stratified.
- Psychometric validation is pending pilot data.
- Composite weighting is theory-driven, not yet empirically optimized.
6. Roadmap
- v1.0 (current): visual + structural release across PHQ-9, GAD-7, RSES.
- v1.1: CFI-Lite layer activates S and R with real data.
- v2.0: pilot-data-driven weight optimization; locale-stratified norms.
- v3.0: trajectory dimension promoted from M visualization to formal axis.
