Registered outcomes 11
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Parental Knowledge of Dental Trauma Emergency Management at Week 4 | Baseline and 4 weeks after randomization (primary comparison at week 4) | Measured by the study-specific 20-item Parental Dental Trauma Knowledge Questionnaire (PDTKQ), comprising multiple-choice items based on dental-trauma first-aid guidance. Scores range from 0 to 100; higher scores indicate better knowledge. Primary analysis compares week-4 scores between randomized groups, adjusting for baseline scores. | ClinicalTrials.gov |
| Primary | Dental Trauma Emergency Decision-Making Accuracy at Week 4 | 4 weeks after randomization (primary comparison); 12-week results recorded separately as follow-up | Measured by a study-specific Dental Trauma Emergency Decision-Making Scenario Test comprising five clinical vignettes addressing avulsion, luxation, crown/root fracture and soft-tissue injury. Scored from 0 to 100 for correctness, completeness and timeliness; higher scores represent more accurate decisions. | ClinicalTrials.gov |
| Secondary | Knowledge Retention at Week 12 | 4 and 12 weeks after randomization | Change in PDTKQ score from week 4 to week 12 (0-100 scale; positive values indicate increased knowledge). | ClinicalTrials.gov |
| Secondary | Parent Confidence in Dental Emergency Management | Baseline, 4 and 12 weeks after randomization | Study-specific 10-item confidence scale with responses scored 0-10 per item. Specify sum/mean and exact final range before submission. | ClinicalTrials.gov |
| Secondary | Satisfaction With Assigned Education Resource | 4 weeks after randomization | Study-specific 12-item satisfaction survey administered in all three groups; define scoring and interpretation in the final protocol. | ClinicalTrials.gov |
| Secondary | Usability of Digital Education Resource | 4 weeks after randomization | System Usability Scale (SUS) completed in the app and AI chatbot arms only; report standard 0-100 SUS score (higher indicates greater perceived usability). | ClinicalTrials.gov |
| Secondary | Engagement With Assigned Educational Resource | During the first 4 weeks after randomization | For app: sessions, modules completed and time on task; for chatbot: sessions and messages; for print: self-reported reading frequency and time. Modality-specific metrics are not directly equivalent and may require separate outcome records. | ClinicalTrials.gov |
| Secondary | Correct Emergency Response to Tooth Avulsion | 4 and 12 weeks after randomization | Prespecified avulsion-vignette subscore from decision-making scenario test, assessing appropriate immediate management. The scoring range must be specified. Distinguish primary-tooth versus permanent-tooth avulsion in the final wording. | ClinicalTrials.gov |
| Other | Parent Anxiety About Managing Dental Emergencies | Baseline and 4 weeks after randomization | Single-item 0-10 numeric rating scale for anxiety, with higher values indicating greater anxiety; clarify exact question text in protocol. | ClinicalTrials.gov |
| Other | Knowledge Score at Week 12 | 12 weeks after randomization | PDTKQ total score 0-100, higher scores indicate better knowledge. | ClinicalTrials.gov |
| Other | Emergency Decision-Making Accuracy at Week 12 | 12 weeks after randomization | Scenario test score 0-100, higher scores indicate better emergency decisions. | ClinicalTrials.gov |
