Stress & Burnout Index Methodology

The Stress & Burnout Index combines two validated, public-domain instruments into a single screening implementation. The first is the Perceived Stress Scale (PSS-10), a 10-item self-report instrument developed by Cohen, Kamarck & Mermelstein (1983) at Carnegie Mellon University and published in the Journal of Health and Social Behavior. The second is the Personal Burnout subscale of the Copenhagen Burnout Inventory, a 6-item subscale developed by Kristensen, Borritz, Villadsen & Christensen (2005) at the Danish National Institute of Occupational Health and published in Work & Stress. Both instruments are public-domain for non-commercial educational use.

The two instruments measure related but distinct constructs. The PSS-10 measures subjective appraisal of demands over the last month — how unpredictable, uncontrollable, and overloaded the respondent has found their life. The CBI Personal Burnout subscale measures cumulative physical and psychological exhaustion as a typical pattern over recent weeks. They are correlated but neither subsumes the other: a person can score high on perceived stress without yet entering burnout territory (early-stage signal) or score high on burnout with normalized perceived stress (the "I'm fine" phase of long-term depletion).

Neither stress nor burnout is a clinical diagnosis. Stress as such does not appear in DSM-5 or ICD-11 as a disorder; it is a transdiagnostic construct relevant to many conditions. Burnout is recognized in ICD-11 as an "occupational phenomenon" but is explicitly not classified as a medical condition. This tool is therefore a screening instrument for two correlated psychological states, not a diagnostic instrument for any specific disorder. A high score on either instrument is reason to consider professional support, not a label.

Why we chose these two instruments

A range of validated stress and burnout instruments exist, each making different trade-offs between brevity, reference period, construct validity, and licensing. The table below summarizes the alternatives we considered and why PSS-10 + CBI Personal Burnout was selected.

The PSS-10 was selected because it is the most-cited, most-validated, and most-widely-translated subjective stress instrument available, and it is public domain — suitable for free deployment with attribution. The CBI Personal Burnout subscale was selected over the MBI because (a) the MBI is proprietary and would preclude free deployment, (b) the CBI Personal Burnout subscale is generic across employment statuses (the MBI Emotional Exhaustion subscale is calibrated to professional-employee respondents), and (c) Kristensen et al. designed the CBI specifically as a public-domain alternative to address the licensing barrier.

The combination of both instruments — rather than either alone — is a deliberate methodology choice. Stress and burnout are correlated but dissociable. Two correlated scores in different conceptual dimensions allow for an integrated archetype assignment that neither instrument alone supports.

The Stress & Burnout Index contains 16 items total: 10 PSS-10 items rated on a 5-point Likert frequency scale (0–4), and 6 CBI Personal Burnout items rated on a 5-point frequency scale (0/25/50/75/100). Total scores range from 0–40 (PSS) and 0–100 (CBI averaged). Response anchors, reproduced verbatim from the original publications:

PSS-10 response anchors (Cohen 1983)

• 0 — Never
• 1 — Almost never
• 2 — Sometimes
• 3 — Fairly often
• 4 — Very often

CBI response anchors (Kristensen 2005)

• 0 — Never / Almost never
• 25 — Seldom
• 50 — Sometimes
• 75 — Often
• 100 — Always

The full 16 items are reproduced below verbatim from the original publications (both public domain). PSS-10 items 4, 5, 7, and 8 are reverse-scored — they are worded in the positive direction (felt confident, things going your way, controlled irritations, on top of things). The tool handles reversal automatically: a raw response of 0 on any of these items contributes 4 to the PSS-10 total, and a raw 4 contributes 0.

The 16 items partition into three sub-dimensions:

• PSS Helplessness — items 1, 2, 3, 6, 9, 10 (6 items, max 24). Negatively-worded; captures unpredictability, uncontrollability, and overload.
• PSS Self-efficacy — items 4, 5, 7, 8 (4 items, max 16 raw). Positively-worded and reverse-scored when computing the PSS-10 total. The raw (non-reversed) sum is reported as a separate sub-dimension representing the perceived-control buffer.
• CBI Personal Burnout — items 11, 12, 13, 14, 15, 16 (6 items, mean 0–100). Cumulative physical and psychological exhaustion. Item 14 ("I can't take it anymore") functions as a clinical sentinel.

Scoring proceeds in five steps: per-item value computation (with reverse-scoring for PSS items 4, 5, 7, 8), PSS-10 total summation, CBI Personal Burnout averaging, severity-band assignment, and archetype classification. Pseudocode for the full algorithm:

// Inputs:
//   pss_responses[q1..q10], each in {0, 1, 2, 3, 4}
//   cbi_responses[q11..q16], each in {0, 25, 50, 75, 100}

// PSS-10 reverse-scored items
const PSS_REVERSED = {"q4", "q5", "q7", "q8"}

// PSS-10 sub-dimensions (Roberti 2006 two-factor structure)
const PSS_HELPLESSNESS = [q1, q2, q3, q6, q9, q10]
const PSS_EFFICACY     = [q4, q5, q7, q8]
const CBI_ITEMS        = [q11, q12, q13, q14, q15, q16]

function pss_item_value(item):
    let raw = pss_responses[item]
    if item in PSS_REVERSED:
        return 4 - raw     // (0->4, 1->3, 2->2, 3->1, 4->0)
    else:
        return raw

// PSS-10 total (0..40) — sum of all 10 adjusted item values
pss_total = sum([pss_item_value(i) for i in q1..q10])

// PSS sub-dimensions (raw, no reversal applied to efficacy items)
helplessness = sum([pss_responses[i] for i in PSS_HELPLESSNESS])  // 0..24
efficacy_raw = sum([pss_responses[i] for i in PSS_EFFICACY])      // 0..16

// CBI Personal Burnout (0..100) — arithmetic mean of 6 items
cbi_score = round(sum([cbi_responses[i] for i in CBI_ITEMS]) / 6)

// PSS-10 severity band (Cohen & Janicki-Deverts 2012 US norms)
function pss_band(total):
    if total <= 13: return "Low stress"          // < 50th percentile
    if total <= 26: return "Moderate stress"     // 50th-80th percentile
    if total <= 32: return "High stress"         // > 80th percentile
    return "Severe stress"                        // top decile

// CBI Personal Burnout severity band (Kristensen 2005)
function cbi_band(score):
    if score <= 24: return "No / Low burnout"
    if score <= 49: return "Moderate burnout"
    if score <= 74: return "High burnout"
    return "Severe burnout"

// Archetype (first-match-wins)
function archetype(pss, cbi):
    if cbi >= 50 and pss >= 27: return "Burnout-onset"
    if pss >= 27 and cbi < 50:  return "Acute Stress"
    if cbi >= 50 and pss < 27:  return "Chronic Exhaustion"
    if 14 <= pss <= 26 and 25 <= cbi <= 49: return "Strained but Coping"
    if pss <= 13 and cbi <= 24: return "Calm Baseline"
    // Fallthrough for low-low / mixed-mod combinations
    if cbi >= 25: return "Strained but Coping"
    return "Calm Baseline"

// Care-aware escalation
function care_aware(pss, cbi, item14_response):
    return cbi >= 75 or pss >= 33 or item14_response >= 75
  

The PSS-10 reverse-scoring rule for items 4, 5, 7, and 8 follows the Cohen 1983 published instructions: the positively-worded items measure perceived self-efficacy, which is conceptually the inverse of perceived stress. A respondent who reports never feeling confident about handling personal problems contributes maximally to the stress total, which is achieved by the (4 − raw) reversal.

The CBI Personal Burnout score is computed as an arithmetic mean of the 6 item responses, not a sum. This follows the Kristensen 2005 published scoring rule and produces a score on the 0–100 scale that maps directly onto the response anchor labels: a score of 25 corresponds to "Seldom" on average, 50 to "Sometimes," 75 to "Often," and so on. Rounding to the nearest integer is applied for display.

The five archetypes follow a first-match-wins decision tree over the two scores. The order of evaluation matters: a high-stress + high-burnout respondent is classified as Burnout-onset rather than separately as both Acute Stress and Chronic Exhaustion. The fallthrough rule at the end of the tree handles edge cases where scores cross severity-band boundaries asymmetrically (e.g., low PSS + moderate CBI defaults to Strained but Coping rather than Calm Baseline).

The care-aware escalation triggers a prominent recommendation panel before the archetype description, and is independent of archetype assignment. It fires under three independent conditions, each chosen to capture a different dimension of clinical concern: severe burnout regardless of stress (CBI ≥ 75), severe stress regardless of burnout (PSS ≥ 33), or endorsement of the "I can't take it anymore" sentinel item at "Often" or "Always" frequency (item 14 ≥ 75) regardless of total scores.

Both instruments have substantial validation literatures across multiple decades, languages, and populations. We summarize key psychometric properties below.

PSS-10 internal consistency

Cronbach's alpha for the PSS-10 has been consistently reported in the α = 0.74–0.91 range across validation studies. Roberti, Harrington & Storch (2006) reported α = 0.89 in a college sample (n = 285); Klein et al. (2016) reported α = 0.84 in a German national probability sample (n = 1,977); Taylor (2015) reported α = 0.91 in a US college sample (n = 911) and α = 0.85 in a US community sample (n = 332). Subscale alphas are lower (helplessness ~0.85, self-efficacy ~0.78) reflecting fewer items per subscale.

PSS-10 two-factor structure

Roberti 2006, Taylor 2015, Klein 2016, and others have replicated a two-factor structure: a Helplessness factor loading on the 6 negatively-worded items (1, 2, 3, 6, 9, 10) and a Self-efficacy factor loading on the 4 positively-worded items (4, 5, 7, 8). The two factors are inversely correlated (r ~= -0.40 to -0.60). A unidimensional model fits less well in confirmatory analyses, supporting separate sub-dimensional reporting rather than total-score-only interpretation. Baik et al. (2019) further showed that the Helplessness factor correlates more strongly with anxiety (GAD-7) and depression (PHQ-9) than the Self-efficacy factor does, consistent with a clinically meaningful sub-dimensional distinction.

PSS-10 concurrent and discriminant validity

The PSS-10 shows expected positive correlations with measures of anxiety and depression and expected negative correlations with measures of social support and resilience. Reported correlations include r ≈ 0.57 with GAD-7 generalized anxiety (Bai 2017), r ≈ 0.59 with PHQ-9 depression (Bai 2017), and r ≈ 0.45–0.65 with the State-Trait Anxiety Inventory across studies. The instrument is sensitive to change over 4–8 week intervals; predictive validity beyond 8 weeks declines per Cohen 1983.

CBI Personal Burnout internal consistency and structure

Cronbach's alpha for the CBI Personal Burnout subscale was α = 0.87 in the original Danish PUMA validation study (Kristensen 2005, n = 1,914). Subsequent international validations have reported α = 0.85–0.93 across English, Mandarin, Spanish, Greek, and Brazilian Portuguese versions. The subscale shows a clear single-factor structure in confirmatory analyses, consistent with its conceptual definition as a unitary measure of cumulative exhaustion.

CBI Personal Burnout test-retest reliability and predictive validity

Borritz, Bültmann, Rugulies et al. (2005) reported 3-year test-retest correlations of r ≈ 0.50–0.65 for CBI subscales in the PUMA cohort. The Personal Burnout subscale predicted future absenteeism, intent to leave the profession, and self-rated health over 3-year follow-up. Söderström et al. (2012) showed that insufficient sleep at baseline predicted clinical burnout 2 years later, with CBI Personal Burnout as the outcome measure — supporting its use as a longitudinal indicator of cumulative depletion.

Combined PSS × CBI discriminant validity

Stress and burnout are positively correlated (r ≈ 0.50–0.70 across studies) but dissociable. The two-axis quadrant plot in this tool's results section is grounded in the empirical finding that high-stress + low-burnout (Acute Stress) and low-stress + high-burnout (Chronic Exhaustion) are real and clinically distinct profiles, not measurement artifacts. The strongest evidence for this dissociation comes from longitudinal work showing that perceived stress shifts faster than burnout in response to acute life events, while burnout reflects accumulated stress exposure that does not normalize even after acute stressors abate.

PSS-10 bands

The four PSS-10 severity bands are anchored to the United States national probability sample reported in Cohen & Janicki-Deverts (2012), which combined data from three population surveys (1983, 2006, 2009; total n ≈ 6,000 US adults). The bands correspond to percentile thresholds in this combined sample:

All four PSS-10 bands are anchored to published percentile data, not author-extrapolated. This is a stronger evidentiary footing than for many tools where intermediate cutoffs are extrapolated between published anchor points.

CBI Personal Burnout bands

The four CBI Personal Burnout bands follow the cutoffs reported in Kristensen et al. (2005) and refined in subsequent CBI validation work:

The CBI bands are conceptually equivalent to "no problem / mild concern / clinical concern / severe concern" but expressed in 25-point intervals matching the response anchor scale. The 50 cutoff between Moderate and High is the published primary cutoff in Kristensen 2005; the 25 and 75 boundaries are conventional applied to the same scale.

Both band schemes are interpretive aids, not diagnostic categories. Users whose scores fall close to a band boundary should not over-interpret which band they were assigned to; the published validations support continuous interpretation of the scores rather than rigid band membership.

Neither the PSS-10 nor the CBI Personal Burnout subscale yields a "diagnosis" in the way a screening tool for depression or anxiety might. There is no diagnostic category of "stress disorder" or "burnout disease" in DSM-5 or ICD-11 against which sensitivity, specificity, and likelihood ratios can be computed in the conventional sense. The instruments instead measure continuous psychological states whose population distributions and downstream outcome associations are well-characterized.

What the bands can support is a probabilistic framing of downstream health risk. Richardson et al. (2012) meta-analyzed 6 prospective cohort studies (n = 118,696, ~10-year follow-up) and reported a relative risk of 1.27 for incident coronary heart disease in the high vs low perceived-stress groups, comparable in magnitude to a 50 mg/dL increase in LDL cholesterol or smoking five additional cigarettes per day. Borritz et al. (2005) reported that high CBI Personal Burnout scores at baseline predicted increased absenteeism (OR = 2.1) and intent to leave the profession (OR = 3.5) over 3 years.

The tool does not attempt to estimate the user's prior probability or compute personalized risk — this would require demographic, medical, and contextual information the screen does not collect. The bands and archetype text are framed in terms of "warrants clinical consideration" and "watch for trajectory" rather than "X% probability of cardiovascular event" precisely because these probabilities cannot be reliably estimated from a self-report screen alone.

PSS-10 US population norms

The most-cited norms come from Cohen & Janicki-Deverts (2012), which pooled three US national probability samples and reported sex-stratified means and percentiles. Selected values (combined 2009 sample, ages 18–65):

Notable patterns: PSS-10 scores are typically 1.5–3 points higher in women than men in US samples; scores have trended slightly upward across the three measurement waves (1983, 2006, 2009); and inverse correlations with age are observed in cross-section, with younger adults reporting higher stress on average.

CBI Personal Burnout norms

The original Kristensen 2005 PUMA cohort (Danish human service workers, n = 1,914) reported a mean Personal Burnout score of 35.8 (SD = 17.5). International validation studies have reported ranges of 30–45 across employed populations. Healthcare worker samples typically report higher means (40–55) and student samples lower means (25–35). Sex differences are smaller for CBI than for PSS-10, with women typically scoring 2–5 points higher than men.

These norms are reference anchors, not targets. A user whose score is at the population mean is not "average" in any normative sense — the population means are themselves elevated by the substantial portion of adults experiencing meaningful stress and burnout. A score below the population mean still warrants attention if the user reports impairment or sustained elevation over months.

Two short self-report screens have inherent limits that no amount of methodological care can overcome. Users should hold these limitations clearly in view when interpreting their results.

1. These are screens, not diagnostic instruments

Neither the PSS-10 nor the CBI Personal Burnout subscale is a diagnostic instrument. There is no diagnosis of "stress" in DSM-5 or ICD-11; "burnout" is recognized in ICD-11 as an occupational phenomenon but is explicitly not classified as a medical condition. A high score is reason to consider professional support, not a label. A trained clinician interviewing the user could distinguish stress-related distress from depression, anxiety, adjustment disorder, post-traumatic adaptation, or alternative explanations that a self-report screen cannot.

2. Reference periods are different across the two instruments

PSS-10 asks about the past month; CBI Personal Burnout asks about typical patterns over recent weeks. The two reference periods are similar but not identical. A user who experienced an acute stress event in the past 30 days but whose typical pattern over recent weeks is calm may report elevated PSS-10 and moderate CBI — this is by design and reflects the dissociation between acute appraisal and cumulative exhaustion. It is also a methodological footnote: the two scores are not measuring the same time window.

3. PSS-10 predictive validity falls off after 4–8 weeks

Cohen 1983 noted that the PSS-10's predictive validity declines rapidly after 4–8 weeks because perceived stress is responsive to changes in life events, daily hassles, and coping resources. A user retaking the screen after 3 months should expect their score to potentially shift — this is informative, not a measurement artifact. Serial administration (quarterly) is the most clinically useful pattern.

4. Does not assess sources of stress or burnout

The instruments measure subjective experience but not its origin. A high PSS-10 in a person with a demanding but meaningful job, in a person navigating bereavement, and in a person with an undiagnosed anxiety disorder will look the same on the screen. The accompanying clinical conversation (or self-reflection) needs to address sources, not just symptoms.

5. Self-report bias and concomitant risks

Self-report instruments are subject to insight limitations. A person who has spent years adapting to chronic stress may not consciously recognize the items that describe them, while a person actively seeking validation for distress may notice items more readily. Alexithymia, depression-related cognitive distortion, and acute psychological state at time of administration all introduce noise.

A separate concern: high-burnout populations have elevated rates of suicidal ideation. Bianchi et al. (2021) 14-sample meta-analysis showed that CBI exhaustion correlates near unity with depressive symptoms after disattenuation. Users with severe burnout scores or item 14 endorsement should treat the care-aware banner seriously regardless of their archetype assignment. The tool's crisis-bar at the top of the page exists for this reason.

6. Does not distinguish burnout from depression

Bianchi 2021 and a substantial body of work argue that burnout's exhaustion dimension is empirically very close to depression. The CBI Personal Burnout subscale does not distinguish "burnout" from "depression presenting as exhaustion." Users with high CBI scores should consider taking the LBL Depression Test (PHQ-9) to clarify which framework better fits their experience.

7. Cultural and gender calibration

Both instruments were developed in Western adult populations (PSS in the US, CBI in Denmark) and have been validated across multiple cultures, but cultural variation in stress expression, help-seeking, and the social acceptability of reporting exhaustion may bias scores. Women systematically report higher PSS-10 scores than men in the same population; whether this reflects true differences in subjective experience or differential reporting thresholds remains debated.

8. Item 14 and suicide-adjacent language

Item 14 ("I can't take it anymore") is included in the CBI Personal Burnout subscale precisely because it captures a clinical sentinel of severe exhaustion. The phrase is not a direct measure of suicidal ideation but is suicide-adjacent: in some respondents, endorsement at "Often" or "Always" frequency may co-occur with thoughts of escape that warrant clinical attention. The care-aware escalation rule fires on item 14 endorsement at ≥ 75 frequency for this reason. Users who endorse this item strongly should treat the result seriously regardless of total scores.

9. Does not screen for comorbidities

Stress and burnout are correlated with anxiety (r ≈ 0.57), depression (correlations approaching unity for burnout-exhaustion), sleep disorders (r ≈ 0.39), and cardiovascular risk (RR = 1.27). The Stress & Burnout Index captures none of these directly. The tool's comorbidity panel and related-tools section exist to surface this. A user with elevated stress or burnout who is also experiencing anxiety, depression, or sleep dysregulation may have multiple distinct conditions that warrant separate consideration.

Methodological choices in this implementation were reviewed by Eskezeia Y. Dessie, PhD, an independent clinical reviewer with expertise in adult psychiatric assessment. The review focused on the following decisions:

1. Instrument selection. Whether PSS-10 + CBI Personal Burnout is a defensible combination for a free public screening tool given the alternatives (MBI, OLBI, Shirom-Melamed).
2. Item reproduction. Verbatim reproduction of all 16 items under public-domain status with explicit citation in three places (tool page, methodology page, schema metadata).
3. Reverse-scoring of PSS items 4, 5, 7, 8. Implementation of the published reversal rule, both in the scoring engine and in the user-facing visual indication on the tool page.
4. Two-factor PSS-10 sub-dimensional reporting. Whether reporting Helplessness and raw Self-efficacy as separate sub-dimensions is empirically supported (Roberti 2006, Taylor 2015) and clinically meaningful.
5. Severity-band derivation. Whether the four PSS-10 bands (anchored to Cohen & Janicki-Deverts 2012 percentiles) and four CBI bands (Kristensen 2005 cutoffs) are anchored honestly and disclosed clearly.
6. Archetype thresholds. Whether the first-match-wins decision tree produces sensible classifications across edge cases (e.g., high-low and low-high stress/burnout combinations).
7. Care-aware framing. Whether the three care-aware triggers (PSS ≥ 33, CBI ≥ 75, item 14 ≥ 75), the crisis-bar placement, and the absence of a hard escalation modal are appropriately calibrated — neither alarmist nor under-warning.
8. Limitations disclosure. Completeness of the limitations section; whether each limitation is accurately characterized.
9. Comorbidity panel framing. Whether the prevalence figures (Bai 2017 PSS-GAD r = 0.57; Bianchi 2021 burnout-depression overlap; Membrive-Jiménez 2022 burnout-sleep r = 0.39; Richardson 2012 PSS-CHD RR = 1.27) are correctly cited and whether the cross-tool referrals serve users honestly rather than as upsell mechanisms.

The review did not extend to clinical use cases, regulatory compliance, or use of the tool in formal diagnostic pathways. This tool is educational decision support and is not validated for clinical diagnostic use.

This methodology page is versioned alongside the tool itself. Substantive changes to the scoring algorithm, severity bands, archetype thresholds, item set, or limitations disclosure are recorded here. Cosmetic and copy-editing changes are not.

• v1.0 — May 9, 2026. Initial release. Implements PSS-10 (Cohen 1983) and CBI Personal Burnout subscale (Kristensen 2005) verbatim under public-domain status. Two PSS sub-dimensions (Helplessness / Self-efficacy raw) plus CBI Personal Burnout. Four PSS bands anchored to Cohen & Janicki-Deverts 2012 US percentiles; four CBI bands anchored to Kristensen 2005. Five archetypes via first-match-wins decision tree integrating both scores. Care-aware escalation at PSS ≥ 33 OR CBI ≥ 75 OR item 14 ≥ 75. Bespoke PSS × CBI quadrant plot visualization. Comorbidity panel anchored to Bai 2017, Bianchi 2021, Membrive-Jiménez 2022, Richardson 2012. Independent review completed by E. Y. Dessie, PhD.

The tool's versioning policy is conservative: any change that alters scoring outputs for the same input will increment the major version (v2.0, v3.0, etc.) and be logged here with a description of the change and its rationale. Users who took the screen in an earlier version will not see their results retroactively recomputed.

Why the PSS-10 and not the MBI?

The Maslach Burnout Inventory (MBI) is the historically dominant burnout instrument with strong psychometric properties and decades of literature. We did not select it because Mind Garden, which holds the copyright, requires per-administration commercial licensing fees that would preclude free deployment on a public website with potential advertising or sponsorship. The CBI Personal Burnout subscale (Kristensen 2005) was specifically developed as a public-domain alternative for exactly this reason. The PSS-10 (Cohen 1983) was likewise selected because it is public domain, has the largest validation literature of any subjective stress instrument, and has the longest reference period (last month) suitable for screening.

Why two instruments, not just one?

Stress and burnout are correlated but dissociable. A user can score high on perceived stress without yet showing cumulative burnout (Acute Stress profile), or score high on burnout with normalized stress (Chronic Exhaustion profile). Either instrument alone would miss one of these patterns. The two-axis quadrant plot in the results section is the visualization that makes this dissociation immediately visible to users; it would not be possible with a single instrument.

Why not just create a custom instrument?

Several reasons. (1) Validated instruments have decades of psychometric work behind them — Cronbach's alpha, factor structure, test-retest reliability, predictive validity, cross-cultural invariance — that a custom instrument would not. (2) Citation matters for credibility; researchers, clinicians, and journalists evaluating the tool will recognize Cohen 1983 and Kristensen 2005 as standard references in their fields. (3) Reusing established instruments is the more honest path: it makes the tool's claims directly comparable to the published literature rather than requiring users to trust LifeByLogic's own validation work.

Why is item 14 treated as a sentinel?

Item 14 ("I can't take it anymore") is included in the CBI Personal Burnout subscale precisely because Kristensen and colleagues identified it as a clinical signal of severe exhaustion. Endorsement at "Often" or "Always" frequency in our care-aware escalation rule (item 14 ≥ 75) reflects the clinical literature's recognition that this specific cognitive content — a felt sense of being unable to continue — warrants attention regardless of the rest of the score profile. The phrase is not a direct measure of suicidal ideation but is suicide-adjacent and should be treated seriously.

Why five archetypes rather than continuous interpretation?

Continuous interpretation of two correlated scores is the methodologically purest approach but is harder for non-expert users to act on. Five archetypes — Burnout-onset, Acute Stress, Chronic Exhaustion, Strained but Coping, Calm Baseline — map the four corners and center of the PSS × CBI plane, providing actionable categorization while the underlying scores remain available for users who want them. The first-match-wins decision tree ensures consistency and transparency: anyone reading the tool's pseudocode can reproduce the same archetype assignment from the same scores.

Why three care-aware triggers instead of one?

The three triggers (PSS ≥ 33, CBI ≥ 75, item 14 ≥ 75) capture three different dimensions of clinical concern. PSS ≥ 33 catches severe acute stress regardless of burnout status. CBI ≥ 75 catches severe burnout regardless of stress appraisal (the chronic-exhaustion case). Item 14 ≥ 75 catches users who endorse the suicide-adjacent sentinel item even if their total scores are below threshold. Any one trigger fires the care-aware banner; using all three ensures we don't miss users in any of these distinct patterns.

What about UCLA Loneliness — is that next?

The UCLA Loneliness Scale-3 (Hughes 2004) and UCLA-20 (Russell 1996) are on the LBL roadmap as a separate Life Dashboard tool. Loneliness and stress/burnout are correlated but conceptually distinct: loneliness is about subjective social disconnection, while stress/burnout are about appraisal of demands. We chose to ship the stress/burnout tool first because the traffic data showed higher search-intent volume; the loneliness scaffold follows as Phase 4 of this build.

Three citations are appropriate when referencing this tool in academic or professional work: one for the LifeByLogic implementation (this page and the tool), and one each for the underlying instruments (Cohen 1983 PSS-10 and Kristensen 2005 CBI), both of which the tool reproduces under public-domain status.

Citing the underlying instruments is appropriate whenever the items themselves or the published validation data are referenced. Citing the LifeByLogic methodology is appropriate when referring specifically to the implementation choices documented on this page (band derivation, archetype thresholds, care-aware logic, comorbidity panel framing).

For complete transparency, all instruments used are public domain. The PSS-10 was released by Cohen, Kamarck & Mermelstein (1983) without restriction; the CBI was released by Kristensen et al. (2005) at the Danish National Institute of Occupational Health under a public-domain license. Both are reproduced verbatim in the LBL implementation; no proprietary scoring or item modifications were made.

The 18 references below underpin the methodology decisions on this page. The two primary instrument citations (#1 Cohen 1983 and #2 Kristensen 2005) are the most critical; the others support specific claims about validation, comorbidity, sex differences, alternative instruments, and downstream outcomes.
