Connor-Davidson Resilience Scale (CD-RISC-10)

1. Abstract

The Connor-Davidson Resilience Scale 10-Item Short Form (CD-RISC-10) is one of the most widely implemented, psychometrically validated, and empirically scrutinized self-report instruments designed to quantify psychological resilience across clinical, occupational, community, and epidemiological populations. Developed by Laura Campbell-Sills and Murray B. Stein (2007) through a rigorous exploratory and confirmatory psychometric refinement of the original 25-item instrument constructed by Kathryn M. Connor and Jonathan R. T. Davidson (2003), the CD-RISC-10 distills the multifaceted resilience construct into an efficient, unidimensional measurement model. The instrument operationalizes psychological resilience as the capacity to effectively adapt to acute stress, recover from trauma or severe hardship, maintain goal-directed persistence amidst obstacles, and successfully navigate distressing affective states.

Comprising exactly ten positively phrased items rated on a 5-point Likert scale ranging from 0 (Not true at all) to 4 (True nearly all the time), the scale yields a composite score spanning 0 to 40, wherein elevated scores denote superior adaptive psychological functioning. Across hundreds of independent empirical investigations worldwide, the CD-RISC-10 has exhibited exceptional psychometric properties, consistently demonstrating high internal consistency (Cronbach’s α typically between .81 and .91; McDonald’s ω > .85), robust test-retest reliability across diverse temporal intervals, and invariant unidimensional factor architecture confirmed through multi-group structural equation modeling across varied demographic, linguistic, and cultural cohorts. Furthermore, the scale demonstrates robust convergent validity with constructs such as self-efficacy, hardiness, dispositional optimism, and psychological well-being, coupled with profound negative associations with post-traumatic stress disorder (PTSD) symptom severity, major depressive disorder symptomatology, generalized anxiety, and perceived chronic stress. Its brevity, structural stability, and sensitivity to therapeutic and psychoeducational interventions render it the preeminent gold-standard instrument for large-scale clinical trials, longitudinal prospective cohorts, and acute psychiatric screenings where minimizing survey participant burden is essential.

4. Purpose

The primary clinical and scientific purpose of the CD-RISC-10 is to provide a brief, psychometrically robust, and reliable measure of an individual’s psychological resilience—specifically operationalized as the constellation of cognitive capabilities, personal agency, and emotional competencies that facilitate rapid recovery and adaptive equilibrium following exposure to severe stressors, physical illness, personal trauma, or adverse life events. While Kathryn Connor and Jonathan Davidson originally introduced the 25-item CD-RISC in 2003 as a multidimensional measure capturing an array of internal attributes (including spirituality, patience, secure relationships, and fatalistic acceptance), subsequent structural equation modeling investigations revealed substantial psychometric instability within that initial multi-factor framework. In response, Campbell-Sills and Stein (2007) sought to eliminate unstable, cross-loading, and redundant items to construct a parsimonious, unidimensional scale that directly captures the core psychological essence of resilient coping.

From a theoretical rationale, resilience is not conceptualized merely as the passive absence of psychopathology in the aftermath of trauma; rather, it denotes an active, dynamic psychological trajectory characterized by effective emotional regulation, cognitive flexibility, persistence toward valued objectives despite profound obstacles, and the subjective appraisal of stress as a catalyst for personal growth. The CD-RISC-10 specifically isolates these central components, omitting secondary attributes such as existential faith or general social support networks, which may act as environmental antecedents or cultural correlates rather than intrinsic resilient competencies per se. By isolating this core latent variable, the instrument minimizes construct confounding, enabling researchers to examine how personal resilience independently interacts with external social resources, genetic vulnerabilities, and environmental affordances.

In applied and clinical environments, the CD-RISC-10 serves several distinct functional purposes:

• Clinical Screening and Risk Stratification: In emergency departments, primary care settings, oncology units, and military operational contexts, administering a 10-item instrument allows clinicians to rapidly identify individuals exhibiting low baseline coping self-efficacy and elevated vulnerability to stress-induced conditions, such as acute stress disorder, major depression, or post-traumatic stress disorder.
• Treatment Outcome Monitoring: Because resilience is a modifiable construct amenable to psychological interventions (e.g., Cognitive Behavioral Therapy, Mindfulness-Based Stress Reduction, Acceptance and Commitment Therapy), the CD-RISC-10 is frequently deployed as a repeated-measures instrument to evaluate the therapeutic efficacy of clinical trials, psychoeducational resiliency workshops, and occupational stress-mitigation protocols.
• Epidemiological and Large-Scale Field Research: In large population-based surveys where respondent fatigue and cognitive burden present serious threats to data fidelity and completion rates, the CD-RISC-10 provides a resource-efficient measurement strategy without sacrificing psychometric precision, structural validity, or predictive power.
• Occupational Assessment in High-Stress Environments: First responders, healthcare workers during health crises, military service members, and corporate leaders frequently undergo evaluation via the CD-RISC-10 to evaluate psychological readiness, detect impending burnout, and calibrate organizational mental health support initiatives.

5. Psychological Construct

The psychological construct evaluated by the CD-RISC-10 is unidimensional psychological resilience, defined as the personal capacity to thrive, maintain psychological equilibrium, and bounce back in the face of adversity, trauma, tragedy, threats, or significant sources of stress. Although the original 25-item parent instrument was hypothesized to encompass five distinct underlying dimensions, Campbell-Sills and Stein’s (2007) extensive psychometric factor analytics demonstrated that a single, robust latent factor explains the covariance among the selected ten items. Nevertheless, this global latent resilience dimension represents an integrated synthesis of several distinct, highly synchronized psychological components:

Hardiness and Cognitive Flexibility (Items 1, 2, and 8)

The capacity to accept, navigate, and dynamically adapt to unpredicted environmental changes is foundational to resilient functioning. Items such as "Able to adapt to change" (Item 1) and "Can deal with whatever comes" (Item 2) operationalize an individual’s cognitive flexibility—the antithesis of cognitive rigidity and catastrophizing. Resilient individuals exhibit high cognitive appraisal plasticity, interpreting novel or threatening circumstances not as immutable catastrophes, but as evolving situations that can be systematically managed. Furthermore, "Not easily discouraged by failure" (Item 8) captures the attributional style described in cognitive theories of hardiness, wherein setbacks are reframed as informational feedback loops rather than definitive reflections of personal inadequacy.

Perceived Self-Efficacy and Goal Persistence (Items 6, 7, and 9)

Drawing deeply from Albert Bandura’s social cognitive theory, self-efficacy constitutes a central pillar of the CD-RISC-10. Item 6 ("Can achieve goals despite obstacles") and Item 7 ("Can stay focused under pressure") assess an individual’s subjective conviction in their operational agency and executive functioning under conditions of acute distress. Rather than succumbing to behavioral avoidance or learned helplessness, resilient agents maintain attentional focus, suppress task-irrelevant affective interference, and sustain goal-directed efforts. Item 9 ("Think of self as strong person") assesses a crystallized, positive self-concept characterized by perceived personal agency, inner strength, and perceived coping competence.

Affective Regulation and Distress Tolerance (Items 3, 4, 5, and 10)

A distinctive feature of the CD-RISC-10 construct is its explicit focus on emotional stamina and the regulation of negative affect. Item 10 ("Can handle unpleasant feelings") measures distress tolerance—the behavioral capacity to experience negative emotional states (such as grief, shame, fear, or frustration) without resorting to maladaptive avoidance strategies, substance misuse, or behavioral disorganization. Item 3 ("Tries to see humorous side of problems") evaluates the deployment of mature, adaptive defense mechanisms, specifically humor, which physiologically and cognitively downregulates the autonomic fight-or-flight response. Item 4 ("Coping with stress can strengthen me") taps into post-traumatic growth and stress-inoculation schemas, reflecting an individual’s cognitive schema that confronting challenges fosters psychological fortitude. Finally, Item 5 ("Tend to bounce back after illness or hardship") directly reflects the physical and psychological elasticity that defines the etymological origin of resilience (from the Latin resilire, to leap back).

6. Theoretical Framework

The construction and validation of the CD-RISC-10 are anchored in several overlapping theoretical traditions within clinical psychology, health psychology, and cognitive-behavioral neuroscience. Rather than adhering to an isolated paradigm, the instrument synthesizes three foundational conceptual frameworks: Kobasa’s Theory of Personality Hardiness, Bandura’s Social Cognitive Theory of Self-Efficacy, and Lazarus and Folkman’s Transactional Model of Stress and Coping.

Kobasa’s Hardiness Model

In her seminal work on stress resistance, Suzanne C. Kobasa (1979) posited that individuals exposed to high levels of life stress who do not develop clinical illness possess a distinct personality structure termed hardiness. Hardiness comprises three interrelated existential dispositions: Commitment (the tendency to involve oneself fully in life activities rather than experiencing alienation), Control (the belief that one can influence events rather than feeling powerless), and Challenge (the anticipation of change as an exciting opportunity for personal growth rather than a catastrophic threat). The CD-RISC-10 directly embeds the Challenge and Control dimensions into its architecture. Items asserting that coping with stress can strengthen an individual, or that one can achieve objectives regardless of adversity, stem directly from Kobasa’s foundational premise that stress can be transformed into a source of psychological mastery.

Bandura’s Social Cognitive and Self-Efficacy Theory

Albert Bandura (1997) defined perceived self-efficacy as an individual’s belief in their capability to organize and execute courses of action required to manage prospective situations. According to Bandura, self-efficacy beliefs determine the choice of behavioral settings, the amount of effort expended, and the duration of persistence in the face of obstacles and aversive experiences. When individuals with high coping self-efficacy encounter severe stressors, they mobilize adaptive behavioral strategies, sustain attentional control, and inhibit maladaptive panic. The CD-RISC-10 functions predominantly as a specialized measure of coping self-efficacy, capturing an individual’s subjective appraisal of their ability to regulate attention under acute pressure, conquer hurdles, and maintain goal pursuit when confronted with repeated failure.

Lazarus and Folkman’s Transactional Model of Stress and Coping

According to Richard S. Lazarus and Susan Folkman (1984), stress is not an environmental stimulus nor an automatic physiological reaction; rather, it is a dynamic transaction between the person and the environment. This transaction depends upon two stages of appraisal: Primary Appraisal (evaluating whether an event represents a threat, harm, or challenge) and Secondary Appraisal (evaluating one’s resources and options for coping with the demands). The CD-RISC-10 measures the cognitive outputs of secondary appraisal. Individuals who endorse items stating they can "deal with whatever comes" or "handle unpleasant feelings" possess high secondary appraisal efficacy, which systematically blunts the perception of environmental demands as overwhelming, thereby downregulating neuroendocrine stress cascades (e.g., hypothalamic-pituitary-adrenal axis activation).

Modern Stress-Inoculation and Neurobiological Plasticity Models

In addition to cognitive frameworks, the CD-RISC-10 aligns with Donald Meichenbaum’s Stress Inoculation model and modern neurobiological models of resilience (e.g., Charney, 2004). Exposure to manageable stress, combined with the successful execution of coping strategies, acts as a psychological "vaccine," restructuring cognitive schemas and prefrontal-amygdala connectivity to facilitate enhanced resilience during subsequent stressors. Item 4 ("Coping with stress can strengthen me") embodies this stress-inoculation principle, capturing the subjective cognitive recognition of psychological adaptation and growth.

7. Validity

The validity of the CD-RISC-10 has been demonstrated through empirical evaluations across diverse international populations, clinical cohorts, and experimental designs. Psychometric studies have established construct, convergent, discriminant, and predictive validity.

Construct and Factorial Validity

In their seminal validation study, Campbell-Sills and Stein (2007) conducted both Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) across three independent undergraduate cohorts (Total N = 1,743). While the parent 25-item CD-RISC failed to conform to Connor and Davidson’s initial 5-factor model across samples, the refined 10-item unidimensional model demonstrated model fit across all validation cohorts. In the final confirmatory sample (Sample 3, n = 541), the single-factor model yielded excellent fit indices: Root Mean Square Error of Approximation (RMSEA) = .044 (90% CI [.028, .060]), Comparative Fit Index (CFI) = .986, and Tucker-Lewis Index (TLI) = .981. Standardized factor loadings across all ten items were high and uniform, ranging from .53 to .76, confirming that each item reliably reflects the underlying resilience construct.

Convergent Validity

Convergent validity has been established through statistically significant associations with established psychological constructs evaluated via external measurement tools:

• Hardiness and Coping Self-Efficacy: CD-RISC-10 scores correlate strongly and positively with the Dispositional Resilience Scale (DRS; r = .68 to .74) and the General Self-Efficacy Scale (GSES; r = .62 to .71).
• Dispositional Optimism: Significant moderate-to-high correlations are documented with the Life Orientation Test-Revised (LOT-R; r = .55 to .64), illustrating that resilient individuals exhibit positive outcome expectancies.
• Adaptive Coping Mechanisms: On the Brief COPE inventory, CD-RISC-10 scores correlate positively with active coping (r = .48), positive reframing (r = .51), and planning (r = .44).
• Purpose and Quality of Life: Strong positive relationships have been identified with the Meaning in Life Questionnaire (MLQ; r = .45) and the Mental Component Summary of the SF-36 (r = .52).

Discriminant Validity

The scale effectively distinguishes psychological resilience from unrelated or inversely related clinical conditions:

• Depressive Symptomatology: CD-RISC-10 scores demonstrate moderate to strong negative correlations with the Patient Health Questionnaire-9 (PHQ-9; r = -.45 to -.62) and the Beck Depression Inventory-II (BDI-II; r = -.51 to -.59).
• Trauma-Related Pathologies: Across clinical military and civilian samples exposed to severe trauma, CD-RISC-10 scores demonstrate robust inverse associations with the PTSD Checklist for DSM-5 (PCL-5; r = -.42 to -.57).
• Neuroticism: On the NEO Five-Factor Inventory (NEO-FFI), resilience exhibits strong negative associations with Neuroticism (r = -.54 to -.66), indicating that the scale does not conflate resilience with emotional stability alone, but measures an active adaptive capability.

Predictive and Criterion-Related Validity

Prospective longitudinal studies demonstrate that baseline CD-RISC-10 scores predict subsequent psychiatric symptom trajectories following adverse life occurrences. For example, in prospective cohorts of emergency first responders, medical personnel, and deploying military service personnel, higher baseline CD-RISC-10 scores predicted lower incidence rates of clinical depression and PTSD following acute traumatic exposure. Furthermore, in clinical randomized controlled trials (RCTs) examining interventions for trauma survivors, changes in CD-RISC-10 scores mediated long-term functional recovery and reductions in overall psychiatric impairment.

8. Reliability

The CD-RISC-10 has exhibited reliability parameters across an extensive range of demographic groups, translation formats, and sample types, including clinical outpatients, university students, geriatric cohorts, corporate workforces, and military combat personnel.

Internal Consistency

Internal consistency evaluates the degree of inter-item correlation within the scale, demonstrating that all items uniformly quantify the same underlying latent construct:

• Original Validation Study (Campbell-Sills & Stein, 2007): Cronbach’s alpha (α) was established at .85 across the primary validation sample, indicating high internal consistency without item redundancy.
• Large General Population Cohorts: In a landmark epidemiological investigation conducted by Wang et al. (2010) involving over 2,000 participants, the CD-RISC-10 demonstrated a Cronbach’s α of .88. In European validation cohorts (e.g., Notario-Pacheco et al., 2011 in Spain; Tourunen et al., 2021 in Finland), alpha coefficients have ranged between .85 and .90.
• Composite Reliability and McDonald’s Omega: Recognizing the psychometric limitations of Cronbach’s α (which assumes tau-equivalence), structural equation modeling investigations have computed composite reliability coefficients (McDonald’s ω). These analyses have consistently reported ω coefficients spanning .86 to .92, demonstrating construct reliability across diverse sample sizes and demographic strata.

Test-Retest Reliability and Temporal Stability

Test-retest reliability verifies that the scale measures a stable psychological construct while maintaining sensitivity to genuine life changes and therapeutic growth:

• Short-Term Stability (2- to 4-Week Intervals): Investigations evaluating the scale over a two-to-four-week hiatus in non-interventional control groups report intraclass correlation coefficients (ICC) ranging between .78 and .88, demonstrating strong test-retest reliability.
• Intermediate-Term Stability (6- to 12-Month Intervals): In longitudinal military research studies, the CD-RISC-10 exhibited a 6-month stability coefficient of r = .65 to .72 in cohorts experiencing non-catastrophic baseline conditions, confirming that while resilience acts as a relatively enduring dispositional trait, it responds dynamically to cumulative acute stressors and environmental changes over extended periods.

9. Factor Analysis

The structural elucidation of the CD-RISC-10 represents an instructive case study in the evolution of psychometric methodology, transitioning from classical exploratory techniques to modern confirmatory factor modeling and measurement invariance testing.

Historical Derivation from the CD-RISC-25

Kathryn Connor and Jonathan Davidson (2003) initially applied an exploratory factor analysis with varimax rotation to their 25-item pool, proposing a five-factor structure comprising: (1) Personal competence, high standards, and tenacity; (2) Trust in one’s instincts, tolerance of negative affect, and strengthening effects of stress; (3) Positive acceptance of change and secure relationships; (4) Control; and (5) Spiritual influences. However, subsequent independent research groups repeatedly encountered significant difficulties replicating this 5-factor model. Multiple items displayed cross-loadings (> .40 on multiple factors), failed to load significantly on their designated factors, or showed localized instabilities across demographic and cultural cohorts.

Campbell-Sills and Stein’s (2007) Structural Refinement

To establish a stable factor structure, Campbell-Sills and Stein conducted iterative factor analyses across independent split-half samples of college undergraduates:

• Exploratory Factor Analysis (Sample 1, n = 665): An initial principal axis factoring with promax oblique rotation on the full 25 items indicated that the majority of the variance was accounted for by a dominant first factor. Items associated with secondary considerations (such as spiritual beliefs or external relational attachments) loaded poorly or inconsistently. The authors systematically removed items with low primary factor loadings (< .40), high cross-loadings (> .35 on multiple factors), or conceptual redundancy. This reduction yielded a parsimonious 10-item unidimensional core scale.
• Confirmatory Factor Analysis (Sample 2, n = 537; Sample 3, n = 541): The single-factor 10-item model was subjected to confirmatory factor analysis using Maximum Likelihood estimation. The unidimensional model demonstrated superior fit compared to multidimensional configurations: χ² (35) = 71.49, p < .001; CFI = .986; TLI = .981; RMSEA = .044 (90% CI [.028, .060]); Standardized Root Mean Square Residual (SRMR) = .031.

Item Parameter Estimates and Factor Loadings

Standardized factor loadings for the CD-RISC-10 are strong and uniformly distributed across items. In the landmark validation literature, standardized factor loadings consistently exceed the .50 cutoff, with most items falling between .60 and .76:

Measurement Invariance Across Subgroups

Subsequent psychometric studies have tested measurement invariance across genders, age groups, and cultures using multi-group structural equation modeling. Research consistently supports full configural, metric (weak), and scalar (strong) invariance across biological sexes and adult age categories, indicating that differences in observed scores reflect true differences in the underlying construct rather than measurement artifact or differential item functioning.

10. Instrument / Measurement Tool

The operational specifications, testing parameters, and administrative structure of the CD-RISC-10 are organized as follows:

• Instrument Name: Connor-Davidson Resilience Scale 10-Item Short Form (CD-RISC-10).
• Instrument Classification: Self-administered psychological assessment instrument / Psychometric rating scale.
• Target Population: Adolescents and adults (aged 12 years and older) across clinical, psychiatric, non-clinical community, corporate, athletic, and military operational settings.
• Item Count: Exactly 10 brief, declarative statements written at a 5th-grade reading comprehension level.
• Administration Time: Approximately 2 to 3 minutes for total completion, ensuring low respondent burden.
• Administration Modality: Paper-and-pencil questionnaire, web-based digital surveys, clinical tablet interfaces, or clinician-assisted administration.
• Authentic Response Scale: 5-point Likert scale:
  • 0 = Not true at all
  • 1 = Rarely true
  • 2 = Sometimes true
  • 3 = Often true
  • 4 = True nearly all the time
• Recall Timeframe: Respondents rate their responses based on how they felt over the past month. In specific longitudinal study protocols, this instruction may assess general or current dispositions.
• Scoring Methodology: Total scores are calculated by summing the response values across all 10 items without weighting:

  CD-RISC-10 Total Score = ∑ (Item 1 through Item 10)

  • Quartile 2 (Scores 30–32): Moderate-low resilience; adequate baseline coping under routine stress, with vulnerability to burnout under sustained severe pressure.
  • Quartile 3 (Scores 33–36): Moderate-high resilience; effective coping mechanisms, good distress tolerance, and capacity for recovery.
  • Quartile 4 (Scores 37–40): Exceptional resilience; characterized by cognitive flexibility, high coping self-efficacy, and sustained equilibrium under extreme adversity.
