Trial Outcomes & Findings for Emotional Processes in VR Exposure Treatment for Flight Phobia (NCT NCT04213859)

NCT ID: NCT04213859

Last Updated: 2026-06-17

Results Overview

The Flight Anxiety Situations Questionnaire (Van Grewen, Spinhoven, Van-Dyck, \& Dikstra, 1999) is a 32-item, 5-point Likert-scale (1= no anxiety to 5=overwhelming anxiety). The FAS evaluates flight-related anxiety in various situations. We used the total score of the FAS which ranges from 32 to 160 with higher values indicating more flight-related anxiety. Thus, higher values reflect worse outcomes, and lower values reflect better outcomes. The total score is obtained by summing all items.

PRIMARY outcome

Timeframe: Two weeks prior to therapy and one week after last therapy session (therapy includes 4 weekly 1-hour sessions over the course of 4 weeks).

The Flight Anxiety Modality (FAM) questionnaire (Van Grewen et al. 1999) assesses somatic and cognitive aspects of Flight Phobia. It includes 18 items that are rated using a 5-point scale (1=not at all, 5=very intensely). We used the total score of the FAM which ranges from 18 to 90, with higher values indicating more flight-related anxiety. Thus, higher values reflect worse outcomes, and lower values reflect better outcomes. The total score is obtained by summing all items.
