EFFECTS OF HORTICULTURAL THERAPY ON ACUTE STRESS AND SALIVARY CORTISOL LEVELS IN HEMODIALYSIS PATIENTS
Sponsor: Ataturk University
Summary
The purpose of this study is to evaluate the acute psychological and physiological effects of a single-session structured horticultural therapy program on patients undergoing routine hemodialysis. The study is designed as a two-arm, parallel, pretest-posttest randomized controlled trial conducted at Bingöl State Hospital. Participants are randomized (1:1) to either an experimental group receiving a 45-60 minute individual horticultural therapy session (e.g., planting and caring for Tagetes erecta, Celosia cristata, and Petunia grandiflora) or a control group maintaining standard waiting conditions for the same duration during non-dialysis days. Primary outcomes evaluate acute changes in state anxiety (measured via STAI-1) and physiological stress response (measured via salivary cortisol concentration) before and immediately after the intervention.

Interventions
Horticultural Therapy
A structured, single-session individual horticultural therapy intervention lasting 45-60 minutes conducted on a non-dialysis day in an outdoor/indoor setting at the hospital campus. Under the guidance of the researcher and following a standardized checklist, participants engage in active hands-on gardening activities using summer-adapted flowering plants (Tagetes erecta, Celosia cristata, Petunia grandiflora). The protocol includes soil preparation, planting seedlings into pots/beds, supporting roots, and initial watering to provide tactile and visual sensory stimulation.
