NCT06095687

Brief Summary

This study will utilize a replicated single case experimental design (RSCD) to investigate the effectiveness of a brief mindfulness meditation (MM) vs clinical hypnosis (HYP) training for improving pain in injured elite athletes. The primary outcome is change in pain intensity. It is hypothesized that: (1) both treatments will engender clinically meaningful improvement in pain intensity; (2) change in cognitive processes will be a unique mechanism underlying improved pain outcome in MM, and (3) change in cognitive content will be a unique mechanism underlying improved pain outcome in HYP. This research program has the potential to reduce athletes' uncertainty around pain, time out with injury and improve pain management during rehabilitation and recovery from injury.

Outcome Measures

Primary Outcomes (1)

  • Numerical Rating Scale (NRS) of Current Pain Intensity

    Change in pain intensity will be measured using a 0-10 numerical rating scale (NRS) of average pain in the past 24 hours. Participants will be asked to choose a number from 0-10 that best represents their pain intensity. Higher scores indicate higher levels of self-reported pain intensity.

    Assessed online daily during randomized baseline length of 5, 10 or 15 days, 5 day treatment period, and randomized post-treatment phase of 5, 10 or 15 days of assessment

Secondary Outcomes (1)

  • Numerical Rating Scale (NRS) of Current Pain Unpleasantness

    Assessed online daily during randomized baseline length of 5, 10 or 15 days, 5 day treatment period, and randomized post-treatment phase of 5, 10 or 15 days of assessment

Other Outcomes (2)

  • Depression Anxiety Stress Scale, 9-item SF, Stress Subscale

    Assessed online daily during randomized baseline length of 5, 10 or 15 days, 5 day treatment period, and randomized post-treatment phase of 5, 10 or 15 days of assessment

  • Positive and Negative Affect Schedule - Serene Affect Subscale

    Assessed online daily during randomized baseline length of 5, 10 or 15 days, 5 day treatment period, and randomized post-treatment phase of 5, 10 or 15 days of assessment

Study Arms (2)

Mindfulness Meditation

ACTIVE COMPARATOR

Condition 1, Mindfulness Meditation (MM): The MM recording will be adapted from Day (2017). It will first instruct the listener to anchor attention on the breath while being mindfully aware of any physical sensations that arise throughout the body. The listener is then encouraged to explore sensations with non-judgmental attentiveness, without attempts to change the sensation in any way. This will implicitly provide training in mindful acceptance. Finally, the listener is instructed to simply label any thinking that arises as "thinking", before returning to the object of the meditation.

Behavioral: Mindfulness Meditation

Clinical Hypnosis

ACTIVE COMPARATOR

Condition 2, Clinical Hypnosis (HYP): The HYP recording will be adapted from Jensen (2011). It will take the listener through a standardised self-hypnosis practice that includes an induction, followed by tailored suggestions. Specifically, the HYP session aims to take the listener through four basic ideas: 1) an induction to get the individual into a state of readiness to accept new ideas; 2) instructions to go to a favourite place to deepen the induction and provide a context for feeling heat while being relaxed; 3) linking suggestions for reducing automatic behavioural inhibition system and behavioural activation system (BIS-BAS) activation in response to stressors and enhancing awareness of when to activate each system; 4) suggestions that target enhancing self-confidence in pain management, well-being and the rehabilitation process; and 5) alerting.

Behavioral: Clinical Hypnosis

Interventions

Five, 20-minute audio-recorded training sessions of mindfulness of breath and body meditation, practiced over consecutive days, delivered remotely via Qualtrics.
