California Critical Thinking Disposition Inventory (CCTDI): A Comprehensive Assessment Tool
Overview and Purpose
The California Critical Thinking Disposition Inventory (CCTDI) is a standardized psychological assessment instrument designed to measure an individual’s disposition—or inclination—to engage in problems and make decisions using critical thinking approaches. Unlike tests that assess critical thinking skills or abilities, the CCTDI specifically evaluates the motivational tendency to apply critical thinking when faced with problems, decisions, or controversial issues.
Development and Theoretical Foundation
The CCTDI was developed by Peter A. Facione and Noreen C. Facione at California State University, Fullerton, based on the American Philosophical Association’s Delphi Report definition of critical thinking. The instrument emerged from recognition that possessing critical thinking skills does not guarantee their application—individuals must also be disposed to use these skills consistently.
The assessment is grounded in the understanding that critical thinking disposition represents a stable personality characteristic that influences whether someone will engage thoughtfully with complex problems rather than relying on intuition, emotion, or superficial analysis.
Core Measured Dispositions
The CCTDI evaluates seven distinct critical thinking dispositions:
Truth-seeking: The tendency to seek the best possible understanding of any given situation, following evidence wherever it leads, and being courageous about asking questions even when inquiry may prove uncomfortable or threatening to one’s beliefs.
Open-mindedness: Tolerance for divergent views and sensitivity to the possibility of one’s own bias, including willingness to consider alternative perspectives and revise opinions when evidence warrants.
Analyticity: Prizing the application of reasoning and evidence to resolve problems, anticipating potential conceptual or practical difficulties, and demanding the use of evidence to support claims.
Systematicity: Valuing organization, focus, and diligence in approaching problems of varying complexity, being systematic in inquiry and learning.
Critical Thinking Confidence: Trust in one’s own reasoning processes and belief that good reasoning will lead to good decisions, while maintaining appropriate confidence in one’s ability to think critically.
Inquisitiveness: Intellectual curiosity and desire for learning even when the application of that learning is not immediately apparent, including eagerness to acquire knowledge and learn explanations.
Maturity of Judgment: Understanding that multiple solutions can be acceptable while recognizing that some judgments are better than others, appreciating the complexity of decision-making in uncertain situations.
Assessment Structure and Administration
The CCTDI consists of 75 Likert-scale items (six-point scale from “strongly agree” to “strongly disagree”) designed to measure the seven dispositions. The instrument typically requires 15-20 minutes to complete and can be administered individually or in group settings.
Each disposition is measured by approximately 10-12 items, with both positively and negatively worded statements to control for response bias. The assessment produces both overall scores and subscale scores for each individual disposition.
Scoring and Interpretation
Scores are calculated for each of the seven dispositions as well as an overall critical thinking disposition score. The standard scoring system uses the following interpretive ranges:
- Strong disposition: Scores above 40 on individual subscales (above 280 overall)
- Positive disposition: Scores between 30-40 on subscales (210-280 overall)
- Ambivalent disposition: Scores between 20-30 on subscales (140-210 overall)
- Negative disposition: Scores below 20 on subscales (below 140 overall)
These ranges indicate the likelihood that an individual will consistently apply critical thinking approaches when confronted with problems or decisions requiring thoughtful analysis.
Psychometric Properties
The CCTDI demonstrates strong reliability with internal consistency coefficients (Cronbach’s alpha) typically ranging from 0.90 to 0.91 for the overall scale and 0.60 to 0.77 for individual subscales. Test-retest reliability over two-week intervals shows correlations of approximately 0.80.
Construct validity has been established through factor analysis confirming the seven-factor structure, and criterion-related validity has been demonstrated through correlations with academic performance, decision-making quality, and other measures of intellectual functioning.
Applications and Uses
Educational Assessment: Measuring student disposition toward critical thinking in academic settings, evaluating the effectiveness of critical thinking curricula, and identifying students who may benefit from disposition-focused interventions.
Professional Development: Assessing workplace readiness for roles requiring analytical thinking, evaluating training program effectiveness in professional contexts, and identifying areas for individual development.
Research Applications: Investigating relationships between critical thinking disposition and various outcomes, studying cultural differences in thinking approaches, and examining factors that influence intellectual engagement.
Clinical and Counseling Contexts: Understanding individual thinking patterns that may affect decision-making, therapeutic progress, or problem-solving approaches in personal situations.
Limitations and Considerations
The CCTDI measures self-reported dispositions rather than actual behavior, introducing potential social desirability bias. Cultural and linguistic factors may influence responses, particularly regarding items related to challenging authority or questioning established beliefs.
The instrument assumes that the seven measured dispositions represent universal aspects of critical thinking, which may not hold across all cultural contexts. Additionally, while disposition predicts thinking behavior, it does not guarantee skilled critical thinking performance.
Relationship to Other Assessments
The CCTDI complements skill-based critical thinking assessments such as the California Critical Thinking Skills Test (CCTST) or Watson-Glaser Critical Thinking Appraisal. While these instruments measure ability to perform critical thinking tasks, the CCTDI evaluates the inclination to engage in such thinking spontaneously.
This distinction proves crucial because individuals may possess critical thinking skills but lack the disposition to apply them consistently, or conversely, may be highly motivated to think critically but lack the necessary cognitive skills.
Contemporary Relevance
In an era characterized by information abundance, complex global challenges, and rapid technological change, the CCTDI provides valuable insights into individual readiness to engage thoughtfully with multifaceted problems. Its emphasis on disposition rather than ability addresses the practical reality that critical thinking skills remain dormant without the motivation to apply them consistently.
The instrument continues to serve as a foundational tool for educators, researchers, and practitioners seeking to understand and develop the intellectual character necessary for effective reasoning in personal, academic, and professional contexts.
