Registered outcomes6
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Competitive State Anxiety Assessed by the Chinese CSAI-2 | Baseline (T0, before the intervention), mid-intervention assessment (T1, week 4), and post-intervention assessment (T2, week 8). The CSAI-2 will be completed 10-12 minutes before the volleyball skill tests at each assessment. | Competitive state anxiety will be assessed using the Chinese version of the Competitive State Anxiety Inventory-2 (CSAI-2), including cognitive anxiety, somatic anxiety and state self-confidence. The primary analysis will examine changes in CSAI-2 scores over time and compare these changes between the cognitive restructuring group and the neutral volleyball referee-instruction group. |
| Primary | Volleyball Skill Performance | Baseline (T0), mid-intervention assessment (T1, week 4), and post-intervention assessment (T2, week 8). | Volleyball skill performance will be assessed using standardized volleyball skill tests adapted from the U18 and libero technical-test criteria of the China Youth Volleyball Teaching and Training Outline (2026) and Volleyball Management Center (2026). The assessment includes five skill domains: serving, reception, spiking, blocking, and defence. Each domain will be scored from 0 to 10 points by combining task achievement or quality (50%) and technical quality (50%). The five domain scores will be summed to produce a total volleyball skill-performance score ranging from 0 to 50 points, with higher scores indicating better performance. Tests will be conducted at baseline (T0), mid-intervention (T1, week 4), and post-intervention (T2, week 8) using standardized procedures and trained raters. |
| Secondary | Sleep Quality Assessed by the Chinese Pittsburgh Sleep Quality Index | Baseline assessment (T0) before the intervention. | Sleep quality will be assessed using the Chinese version of the Pittsburgh Sleep Quality Index (PSQI). The PSQI evaluates subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleep medication and daytime dysfunction. The PSQI score will be used as a baseline control variable in the analysis, with higher scores indicating poorer sleep quality. |
| Secondary | Trait Sport Anxiety Assessed by the Chinese SAS-2 | Baseline (T0), mid-intervention assessment (T1, week 4), and post-intervention assessment (T2, week 8). | Sport anxiety will be assessed using the validated Chinese version of the Sport Anxiety Scale-2 (SAS-2) at baseline, mid-intervention, and post-intervention assessments. The 15-item scale measures worry, somatic anxiety, and concentration disruption. Each item is scored from 1 to 4, and total and subscale scores will be calculated according to the validated scoring procedure. Higher scores indicate greater sport anxiety. Changes in SAS-2 scores over time and differences between the cognitive restructuring group and the neutral volleyball referee-instruction group will be analyzed as a secondary outcome. |
| Secondary | Mental Effort Assessed by the Rating Scale of Mental Effort (RSME) | Baseline (T0), mid-intervention assessment (T1, week 4), and post-intervention assessment (T2, week 8). | Mental effort during the volleyball skill tests will be assessed using the Rating Scale of Mental Effort (RSME). The RSME score will be recorded after each assessment session, with higher scores indicating greater perceived mental effort. |
| Other | Processing Efficiency Index (PEI) | At baseline, mid-intervention assessment (T1, week 4), and post-intervention assessment (T2, week 8), after completion of the volleyball skill test and RSME assessment. | An exploratory derived index calculated from standardized overall volleyball skill performance and Rating Scale Mental Effort (RSME) scores. PEI will be calculated as z-standardized overall volleyball skill performance minus z-standardized RSME score: PEI = z(skill performance) - z(RSME). Higher values indicate relatively better skill performance achieved with lower perceived mental effort. Overall skill performance and RSME scores will also be analyzed separately. No clinical cut-off value will be used. |
