Conditions
Interventions
Intervention Name: VR-Based Interview Training (for Child Welfare Support Workers) Intervention Period: 2 weeks Intervention Sessions/Frequency: Total of 3 sessions (1-2 sessions per week, completed
Dose: Standalone HMD (e.g., 6DoF, refresh rate 60-90Hz, display brightness at standard settings, no additional radiation exposure) Controller or hand-tracking operation Heart rate variability
= 250 Hz recommended) Assessment Timepoints: STAI (State-Trait Anxiety Inventory): baseline (pre-intervention), immediately after each session (primary outcome at final session), and 1-month fol
rest for 10-15 minutes, if not improved discontinue the session Discontinue if HR increases abruptly compared to baseline (e.g., +40 bpm or more) with symptoms Postpone session in case of illnes
