About this trial
The aim of this study is to investigate the effects of aromatherapy with lavender and bergamot essential oils on anxiety, vital signs, and feelings of embarrassment before colonoscopy. The findings of this study are expected to contribute both to filling a gap in the literature and to the planning of evidence-based nursing interventions aimed at minimizing pre-colonoscopy anxiety and embarrassment in patients.

Treatments tested in this trial
Lavender Aromatherapy
Other interventionParticipants will inhale lavender essential oil via cotton pads placed near the nose for 20 minutes prior to colonoscopy. The application will take place in a pre-procedure waiting area under nurse supervision.
Bergamot Aromatherapy
Other interventionParticipants will inhale bergamot essential oil through cotton pads placed near the nose for 20 minutes before the colonoscopy procedure, under the supervision of clinical staff.
Placebo Inhalation
Other interventionParticipants will inhale an odorless substance (distilled water) using the same method and duration as the intervention groups, to simulate the aromatherapy procedure.

Trial outcomes
Primary outcomes
1
Change in anxiety level measured by the State Anxiety Inventory (STAI-State)
Anxiety will be assessed using the State Anxiety Inventory (STAI-State), which consists of 20 items rated on a 4-point Likert scale. The total score ranges from 20 to 80, with higher scores indicating greater anxiety. The scale has been validated in Turkish with a Cronbach's alpha between 0.94 and 0.96.
Time frame
Immediately before and 30 minutes after the interventionSecondary outcomes
1
Change in embarrassment level measured by the Colonoscopy Embarrassment Scale
Embarrassment related to colonoscopy will be measured using the 15-item Colonoscopy Embarrassment Scale, with scores ranging from 15 to 60. Higher scores indicate greater embarrassment. The Turkish version has a Cronbach's alpha of 0.94.
Time frame
Immediately after the colonoscopy procedureOther outcomes
1
Change in heart rate
Heart rate (beats per minute) will be measured using a standard monitoring form.
Time frame

Change in respiratory rate
Respiratory rate (breaths per minute) will be measured using a standard monitoring form.
Time frame
