NCT06365736

Brief Summary

The goal of this randomized control trial is to test if contemplating in nature could benefit spiritual well-being in general adults. The main question it aims to answer is: Does a 2-week contemplative nature intervention improve spiritual well-being? Participants in the intervention condition will walk for 10 minutes and then choose a nice spot to sit for 10 minutes. During these minutes they will be asked to be silently present and observe trees, plants, flowers, or other aspects of nature and contemplate their connectedness to nature and their own awareness. Then walk back 10 minutes.

Outcome Measures

Primary Outcomes (6)

  • Spiritual well-being assessed by Spiritual Attitude and Involvement List Short Form (SAIL-SF)

    On a 6-point Likert scale ranging from 1 (not at all) to 6 (to a very high degree), respondents rate in how far they think specific statements about spiritual well-being apply to themselves. Higher scores indicate higher scores of spiritual well-being.

    Change from baseline to post-intervention at 2 weeks.

  • Spiritual well-being assessed by Spiritual Attitude and Involvement List Short Form (SAIL-SF)

    On a 6-point Likert scale ranging from 1 (not at all) to 6 (to a very high degree), respondents rate in how far they think specific statements about spiritual well-being apply to themselves. Higher scores indicate higher scores of spiritual well-being.

    Change from Baseline to Short-term follow-up at 1 month.

  • Spiritual well-being assessed by Spiritual Attitude and Involvement List Short Form (SAIL-SF)

    On a 6-point Likert scale ranging from 1 (not at all) to 6 (to a very high degree), respondents rate in how far they think specific statements about spiritual well-being apply to themselves. Higher scores indicate higher scores of spiritual well-being.

    Change from baseline to longer-term follow-up at 3 months.

  • Spiritual well-being assessed by Daily Spiritual Experience Scale (DSES)

    The non-theistic items from DSES will be used. Ranging from 1 (multiple times a day) to 6 (never). The item responses were reverse coded prior to analysis so that larger values would reflect a higher level of daily spiritual experiences.

    Change from baseline to post-intervention at 2 weeks.
