Summary

The goal of this randomized controlled trial is to evaluate whether a nature-based contemplation intervention can enhance spiritual well-being and reduce grief symptoms among adults with moderate prolonged grief symptoms. The main questions it aims to answer are:

Does a nature-based contemplation intervention improve spiritual well-being compared to an active control condition (noticing nature) and a waitlist control condition?

Does a nature-based contemplation intervention reduce grief severity and improve mental well-being, nature connectedness, selflessness, ability to adapt, personal recovery, and elevation compared to control conditions?

How do spiritual well-being, ability to adapt, nature connectedness, selflessness, grief reactions, and positive/negative affect change during the intervention period?

Researchers will compare a nature-based contemplation intervention to both a noticing-nature active control group and a waitlist control group to isolate mindfulness-specific effects from possible general nature exposure benefits.

Participants will:

Complete baseline, post-intervention, and follow-up assessments (at one and three months) Engage in either 10 sessions of nature-based contemplation practice or noticing nature activities over a two-week period (intervention and active control groups) Provide daily diary responses about their experiences throughout the 14-day intervention period

Interventions

BEHAVIORAL

Nature-based contemplation

The intervention consisted of a daily 30-minute self-guided practice structured in three parts: (1) participants first walked mindfully for 10 minutes in a natural environment of their choosing (e.g., local park, forest, garden), (2) upon reaching a suitable location, they engaged in a 10-minute guided contemplative practice, and (3) concluded with a 10-minute mindful walk back.

BEHAVIORAL

Noticing-nature

Participants allocated to the noticing-nature active control group will be instructed to walk in nature for 30 minutes per day and pay attention to how the natural objects/scenes they encounter in their daily surroundings make them feel over the 14-day period.
