Brief Summary

Self-efficacy refers to the perceived belief to cope effectively, by personal efforts, with challenging situations and problems (Bandura, 1977). Basic research has shown that increases in perceived self-efficacy can enhance the extinction of fear (Zlomuzica et al., 2015). This study is aimed at translating these findings into a useful clinical application to augment exposure-based treatment outcome.

Outcome Measures

Primary Outcomes (3)

  • Change in the Behavioral Approach Test (BAT)

    from pretreatment through follow-up (i.e. baseline, approx. 2-3 days after treatment, 1 month after)

  • Change in subjective fear during the BAT

    Subjective fear during the BATs will be measured using the Subjective Units of Distress Scale (SUDS)

    from pretreatment through follow-up (i.e. baseline, approx. 2-3 days after, 1 month after)

  • Change in heart rate reactivity during the BAT

    from pretreatment through follow-up (i.e. baseline, approx. 2-3 days after, 1 month after)

Secondary Outcomes (4)

  • Change in Acrophobia Questionnaire (AQ)

    assessed from pre-treatment through follow-up (i.e. baseline, approx. 2-3 days after, 1 month after

  • Change in Attitude Towards Heights Questionnaire (ATHQ)

    assessed from pre-treatment through follow-up (i.e. baseline, approx. 2-3 days after, 1 month after

  • Change in Danger Expectancy Scale (DES)

    assessed from pre-treatment through follow-up (i.e. baseline, approx. 2-3 days after, 1 month after

  • Change in Anxiety Expectancy Scale (AES)

    assessed from pre-treatment through follow-up (i.e. baseline, approx. 2-3 days after, 1 month after

Other Outcomes (9)

  • Change in perceived self-efficacy

    assessed three times on day 1: before and after the exposure session as well as after the intervention; assessed once at posttreatment (window: 2-3 days after exposure treatment); assessed once at follow-up (window: 1 month after treatment)

  • Becks Depression Inventory II (BDI II)

    assessed at pre-treatment (day 1)

  • State-Trait Anxiety Inventory (STAI)

    assessed at pre-treatment (day 1)

  • +6 more other outcomes

Study Arms (3)

Exposure + self-efficacy enhancement

EXPERIMENTAL

After the virtual exposure session, participants will receive instructions to recall the exposure session with a focus on the personal mastery experiences/achievements made during exposure.

Other: Self-efficacy enhancement

Exposure + control intervention

ACTIVE COMPARATOR

After the virtual exposure session, participants will receive instructions to recall the exposure session

Other: Control intervention

Exposure only

NO INTERVENTION

Treatment as usual: no intervention after the exposure session will be given.

Interventions

specific instructions regarding the retrieval of mastery experiences during exposure will be given (e.g., pointing out discrepancies between expected negative consequences and actual outcome during exposure; focus on achievements)

Exposure + self-efficacy enhancement

specific instructions regarding the retrieval of the exposure session will be given without an emphasis on personal mastery experience (e.g., description of details regarding the virtual reality environment)

Exposure + control intervention
