Registered outcomes9
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Structural Validity of OHIP-EDENT-RU Assessed by Confirmatory Factor Analysis | Baseline questionnaire assessment in the main psychometric sample; anticipated February-September 2027. | Fit of the prespecified one-, three-, and seven-factor models assessed using CFI, TLI, RMSEA, and SRMR, with standardized factor loadings and inter-factor correlations. |
| Secondary | Internal Consistency of OHIP-EDENT-RU | Baseline questionnaire assessment in the main psychometric sample; anticipated February-September 2027. | Cronbach alpha, McDonald omega, 95% confidence intervals, and corrected item-total correlations for the total score and supported subscales. |
| Secondary | Test-Retest Reliability and Measurement Error | Repeat questionnaire 10-14 days after baseline; anticipated February-October 2027. | Absolute-agreement intraclass correlation coefficients with 95% confidence intervals, standard error of measurement (SEM), and smallest detectable change (SDC95) among 60-80 clinically stable participants. |
| Secondary | Construct Validity of OHIP-EDENT-RU | Baseline questionnaire assessment in the main psychometric sample; anticipated February-September 2027. | Spearman correlations with denture-satisfaction VAS and global oral-health self-rating, and comparison of participants with versus without a routine clinical indication for denture replacement. |
| Secondary | Item Response Distributions of OHIP-EDENT-RU | Baseline questionnaire assessment in the main psychometric sample; anticipated February-September 2027. | For each of the 19 OHIP-EDENT-RU items, the percentage of non-missing responses in each response category will be reported. Unit of measure: percentage. |
| Secondary | Total-Score Distribution of OHIP-EDENT-RU | Baseline questionnaire assessment in the main psychometric sample; anticipated February-September 2027. | Distribution of OHIP-EDENT-RU total scores in the main psychometric sample. Unit of measure: OHIP-EDENT-RU total-score points. |
| Secondary | Missing Item Responses of OHIP-EDENT-RU | Baseline questionnaire assessment in the main psychometric sample; anticipated February-September 2027. | For each of the 19 OHIP-EDENT-RU items, the percentage of participants with a missing response will be reported, using all participants assessed in the main psychometric sample as the denominator. Unit of measure: percentage. |
| Secondary | Floor Effect of the OHIP-EDENT-RU Total Score | Baseline questionnaire assessment in the main psychometric sample; anticipated February-September 2027. | Percentage of participants with the minimum possible OHIP-EDENT-RU total score among participants with a calculable total score in the main psychometric sample. Unit of measure: percentage. |
| Secondary | Ceiling Effect of the OHIP-EDENT-RU Total Score | Baseline questionnaire assessment in the main psychometric sample; anticipated February-September 2027. | Percentage of participants with the maximum possible OHIP-EDENT-RU total score among participants with a calculable total score in the main psychometric sample. Unit of measure: percentage. |
