Registered outcomes 11
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Pain Intensity | Immediately before and after the 15-minute intervention | Current pain intensity will be assessed using a 0-10 numeric rating scale, with 0 indicating no pain and 10 indicating the worst pain imaginable. Pain intensity will be assessed immediately before and after the intervention; the primary analysis will compare post-intervention ratings across experimental conditions while adjusting for the corresponding pre-intervention rating. | ClinicalTrials.gov |
| Primary | Pain Unpleasantness | Immediately before and after the 15-minute intervention | Current pain unpleasantness will be assessed using a 0-10 numeric rating scale, with 0 indicating not at all unpleasant and 10 indicating extremely unpleasant. Pain unpleasantness will be assessed immediately before and after the intervention; the primary analysis will compare post-intervention ratings across experimental conditions while adjusting for the corresponding pre-intervention rating. | ClinicalTrials.gov |
| Secondary | Anxiety | Immediately before and after the 15-minute intervention | Current anxiety will be assessed using a 0-10 numeric rating scale, with 0 indicating not at all anxious and 10 indicating extremely anxious. Anxiety will be assessed immediately before and after the intervention; analyses will compare post-intervention ratings across experimental conditions while adjusting for the corresponding pre-intervention rating. | ClinicalTrials.gov |
| Secondary | Desire for Pain Medication | Immediately before and after the 15-minute intervention | Current desire for pain medication will be assessed using a 0-10 numeric rating scale, with 0 indicating no desire at all and 10 indicating the strongest possible desire. Desire for pain medication will be assessed immediately before and after the intervention; analyses will compare post-intervention ratings across experimental conditions while adjusting for the corresponding pre-intervention rating. | ClinicalTrials.gov |
| Secondary | Change in Frontal-Midline Theta Power | During the 15-minute intervention relative to the 5-minute pre-intervention resting baseline | EEG frontal-midline theta power in the 4-8 Hz frequency band will be measured over a prespecified frontal-midline region of interest centered on Fz, FCz, and Cz. Mean theta power during the assigned exercise will be expressed relative to the 5-minute eyes-closed resting baseline. | ClinicalTrials.gov |
| Other | Mindfulness | Immediately before and immediately after the 15-minute intervention | State mindfulness will be assessed using the 3-item state version of the Metacognitive Processes of Decentering scale (MPoD-3). Scores will be assessed immediately before and after the intervention to characterize intervention-related changes in state mindfulness. | ClinicalTrials.gov |
| Other | Self-Transcendence | Immediately before and immediately after the 15-minute intervention | State self-transcendence will be assessed using the 3-item state version of the Nondual Awareness Dimensional Assessment (NADA-3). Scores will be assessed immediately before and after the intervention to characterize intervention-related changes in state self-transcendence. | ClinicalTrials.gov |
| Other | Pre-Intervention Treatment Expectancy | Immediately before the expectancy manipulation and 15-minute intervention | Expected effectiveness of the mindfulness exercise for reducing pain will be assessed using a 0-10 numeric rating scale, with 0 indicating not at all effective and 10 indicating extremely effective. | ClinicalTrials.gov |
| Other | Post-Intervention Treatment Credibility | Immediately after the 15-minute intervention | Perceived credibility or believability of the exercise as a pain-management technique will be assessed using a 0-10 numeric rating scale, with 0 indicating not at all credible and 10 indicating extremely credible. | ClinicalTrials.gov |
| Other | Number of Participants Reporting an Unpleasant or Adverse Experience | Immediately after the 15-minute intervention | Participants will indicate whether they experienced an unpleasant or adverse experience during the intervention using a Yes/No item. Participants responding Yes will have the opportunity to provide a free-text description of the experience. | ClinicalTrials.gov |
| Other | Perceived Sociocultural Scaffolding of the Study Encounter | Immediately after the post-exercise processing period, prior to debriefing. | Perceived sociocultural features of the study encounter will be assessed using a 12-item exploratory questionnaire developed for this study. Participants will rate each item on a 1-7 Likert scale ranging from strongly disagree to strongly agree. The questionnaire includes four 3-item subscales assessing: (1) appeal to expert authority, (2) relational alliance-building, (3) ritualization of study procedures, and (4) co-constructed meaning-making. Higher scores on each subscale indicate greater perceived presence of that sociocultural scaffold. | ClinicalTrials.gov |
