Competitive State Anxiety Inventory-2 (CSAI-2)

Also known as: CSAI-2, Competitive State Anxiety

The CSAI-2 is a 27-item instrument measuring three dimensions of state anxiety in sport: cognitive anxiety (worry), somatic anxiety (physiological arousal), and self-confidence. Developed by Martens and colleagues in 1990, it has become the gold standard for assessing pre-competition psychological state and is widely used in sport psychology research, coaching, and athlete support.

When to use it

Pre-competition psychological assessment in individual or team sports; coaching staff monitoring of athlete readiness before high-stakes competitions; identification of athletes experiencing excessive competitive anxiety warranting mental skills intervention; research on anxiety–performance relationships; evaluation of anxiety management interventions (cognitive restructuring, arousal control); team psychological profiling; longitudinal tracking of psychological state across a competitive season; multi-sport talent development programs monitoring psychological resilience.

Strengths & limitations

Strengths
  • Sport-specific construct: Unlike general anxiety measures, CSAI-2 explicitly measures competitive anxiety in the immediate pre-competition context, directly relevant to athletic performance.
  • Multidimensional: Separates cognitive and somatic anxiety, recognizing they have different correlates and interventions; cognitive anxiety responds to thought-challenging, somatic to relaxation.
  • Includes self-confidence: Self-Confidence subscale provides a concurrent measure of outcome expectancy, complementing anxiety assessment and capturing resilience factors.
  • Psychometrically robust: Extensive evidence for reliability (internal consistency α > .75 per subscale) and validity across 30+ years of research; cross-cultural validations available.
  • Brief and practical: 3-minute administration fits pre-competition time constraints; minimal burden for athletes; can be administered by coaches without formal training.
  • Bidirectional interpretation: Recent research (Bigelow et al., 2014; Chandler et al., 2016) shows athletes can reappraise somatic symptoms as facilitative (challenge) rather than detrimental (threat), informing interventions.
Limitations
  • State measurement only: CSAI-2 measures anxiety in the immediate pre-competition moment; does not assess trait anxiety or chronic competitive anxiety patterns.
  • Timing sensitivity: Scores vary substantially by assessment time relative to competition onset (30 min, 1 hour, 2 hours); small differences in timing produce score variation.
  • Directional reappraisal complexity: While direction (Threat vs. Challenge) has theoretical appeal, empirical evidence for its predictive validity is mixed; simpler subscale scores are more reliable.
  • Sport and cultural variation: Norms and factor structure vary across sports and cultures; generic interpretation without sport-specific norms may be inaccurate.
  • Confounding with competence: Self-Confidence in CSAI-2 reflects expected performance outcome, not actual skill level; a low-confidence high-skill athlete requires different intervention than a high-confidence low-skill athlete.

Frequently asked

Is high CSAI-2 anxiety always bad for performance?

No. Research shows a non-linear relationship: moderate arousal often optimizes performance (Yerkes-Dodson law). Some high-performing athletes report high Cognitive Anxiety (>25) but reframe it as 'focused intensity' rather than worry. The key is whether anxiety impairs focus/execution. Athletes with high anxiety but intact self-confidence often perform well. Monitor individual performance patterns, not absolute scores.

How far before competition should I administer CSAI-2?

Standard timing is 30 minutes to 2 hours before competition onset. This captures competitive state anxiety—the anxiety specific to the immediate competition. Administering 24 hours before or in training sessions will not reflect competition-day anxiety. Always document assessment time relative to competition start. For multi-event competitions (day-long tournament), reassess before each major event.

Can I use CSAI-2 to diagnose an anxiety disorder?

No. CSAI-2 measures state anxiety in the competitive context; elevated CSAI-2 does not indicate clinical anxiety disorder. Many athletes with clinical anxiety manage competitive anxiety well with coping skills; conversely, some athletes with no clinical anxiety experience high competitive anxiety. If an athlete reports excessive anxiety outside sport or persistent worry impacting daily life, refer to a mental health professional for formal evaluation.

What if my athlete has high Somatic Anxiety but high Self-Confidence?

This is a favorable profile: the athlete experiences physiological arousal (quickened heart rate, muscle tension) but trusts their ability to perform. This arousal is often channeled productively as energy and focus. Encourage the athlete to interpret symptoms as 'activated readiness' rather than fear. Brief somatic techniques (deep breathing, muscle relaxation) can modulate intensity if needed, but aggressive anxiety reduction may blunt useful arousal.

Can I compare my athlete's CSAI-2 scores to norms from a different sport?

Not recommended. Anxiety profiles vary significantly across sports: gymnasts may have higher anxiety than tennis players; team sport athletes may show different patterns than individual sport athletes. Always use sport-specific norms when available, or establish within-athlete baselines across multiple competitions in the same sport. Generic norms risk over- or under-interpreting scores.

Should I try to reduce my athlete's anxiety score to zero?

No. Optimal anxiety is not zero. Most athletes perform best with some physiological arousal and mental focus; trying to eliminate all anxiety may dull responsiveness. Work toward the athlete's individually optimal arousal level (identified through performance tracking across multiple competitions) and help them channel that arousal productively through cognitive reappraisal and attentional focus.
