About this trial
This randomized controlled study aims to investigate the effects of an electrodermal activity (EDA)-based adaptive support system on performance during virtual reality (VR)-based advanced life support (ALS) training. Participants' stress levels will be continuously monitored through EDA during the simulation. When stress exceeds a predefined threshold, the adaptive system will automatically activate a support mode that provides additional guidance and time. The performance outcomes of participants receiving adaptive support will be compared with those receiving standard VR training. The study will also examine the role of presence, anxiety, social anxiety, and personality traits in the relationship between stress and performance.

Treatments tested in this trial
EDA-Based Adaptive Support System
Other interventionParticipants receive VR-based advanced life support training with an electrodermal activity (EDA)-based adaptive support system that automatically provides additional guidance, more frequent instructions, and extended response time when stress levels exceed a predefined threshold.
Standard VR-Based Training
Other interventionParticipants receive standard VR-based advanced life support training without adaptive support. Although electrodermal activity (EDA) is monitored during the simulation, the training flow remains unchanged regardless of stress levels.
Treatment groups
72 Participants
are divided into 2 treatment groupsGroup A: Adaptive SupportExperimental treatment 1 intervention
Group B: Standard TrainingExperimental treatment 1 intervention
Trial outcomes
Primary outcomes
1
Advanced Life Support Performance Score
Participants' performance during the post-training VR-based advanced life support examination will be automatically evaluated by the simulation system. The score will reflect the accuracy and completeness of advanced life support procedures performed without guidance. Scores will range from 0 to 100 with higher scores indicating better success.
Time frame
Up to 4 weeksSecondary outcomes
1
Electrodermal Activity (EDA) Level
Description: Participants' physiological stress responses during the VR simulation will be continuously measured using electrodermal activity recordings. Baseline and training-phase EDA values will be analyzed. Higher EDA levels will suggest higher stress levels.
Time frame
Up to 4 weeks2
Presence Score
Participants' sense of presence in the VR environment will be assessed using the Turkish adaptation of the Presence Questionnaire developed by Witmer and Singer (1998). Higher scores indicate a stronger sense of immersion and realism in the virtual environment.
Time frame
Up to 4 weeks3
State Anxiety Score
articipants' situational anxiety levels following the VR training will be assessed using the State Anxiety subscale of the State-Trait Anxiety Inventory (STAI). Scores will range from 1 to 4 and higher scores will indicate higher anxiety levels.
Time frame
Up to 4 weeks4
Trait Anxiety Score
Participants' general tendency toward anxiety will be assessed using the Trait Anxiety subscale of the State-Trait Anxiety Inventory (STAI). Scores will range from 1 to 4 and higher scores will indicate higher anxiety levels.
