NCT06788119

Brief Summary

The aim of this study is to develop and test the efficacy of first-of-its-kind, fully instrumented sensor-based smartphone-guided in-vivo exposure therapy using a just-in-time intervention for anxiety disorder. The main hypotheses are:

  1. 1.Both treatment conditions (CBT treatment with IVE and CBT treatment with IVE+SYMPTOMS-JIT) will show efficacy and no statistically significant differences will be found between them. The efficacy will be determined for the differences in pre-post treatment in the used outcome measures.
  2. 2.The therapeutic gains obtained in both treatment conditions (IVE and (IVE+SYMPTOMS-JIT) will be maintained at 1-, 6-, and 12-month follow-up periods.
  3. 3.Both treatment conditions will be efficient, that is, they will be well-valued by patients and therapists. However, IVE+SYMPTOMS-JIT will be preferred and perceived as less aversive than IVE.
  4. 4.The main barriers for the use of this technology are not technological, but rather attitudinal and they can be identified through qualitative studies.

Outcome Measures

Primary Outcomes (2)

  • Anxiety Disorders Interview Schedule for DSM-IV-TR (ADIS-IV)

    It is a specific diagnostic semistructured interview for the diagnosis of anxiety disorders. Phobias, Agoraphobia and Social Phobia Sections will be used. For the majority of anxiety disorders, this interview has demonstrated appropriate psychometric qualities and good to exceptional reliability (Orsillo \& Roemer, 2001). This instrument includes relevant clinical measures such as interference and distress as perceived by the participant on a scale from 0 to 8 (wherein 0 = "Not at all" and 8 = "Very severe")

    Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)

  • Fear and avoidance scales

    The participants and therapists identify the situations and physical sensations that cause the participants the most fear and distress, as well as the negative thoughts associated with them. Next, they assess, on a scale of 0-10, the degree of fear (0="no fear"; 10="extreme fear") and avoidance (0="never avoid"; 10="always avoid") for each feared situation and sensation. In addition, the degree of belief in the negative thoughts related with the target behaviors and sensations are also assessed, using a scale ranging from 0 ("I do not believe the content of the thought at all") to 10 ("I believe the thought is totally true")

    Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)

Secondary Outcomes (14)

  • Severity Measure for Specific Phobia - Adult

    Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)

  • Acrophobia Questionnaire

    Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)

  • Claustrophoby Questionnaire

    Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)

  • Fear of Flying Questionnaire II

    Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)

  • Anxiety Sensitivity Inventory

    Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)

  • +9 more secondary outcomes

Other Outcomes (10)

  • DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition)

    Baseline, up to 12 weeks (average)

  • The Clinician Severity Scale

    Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)

  • Item Short Form Health Survey (SF-12)

    Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)

Study Arms (2)

CBT Treatment with in vivo exposure

ACTIVE COMPARATOR

In this condition participants will receive CBT treatment and be exposed to in vivo situations.

Behavioral: Cognitive behavioral therapy with in vivo exposure

CBT Treatment with in vivo exposure plus SYMPTOMS-JIT

EXPERIMENTAL

In this condition participants will receive CBT treatment and be exposed to in vivo situations with the support of SYMPTOMS-JIT.

Behavioral: Cognitive behavorial therapy with in vivo exposure plus SYMPTOMS-JIT

Interventions

CBT will be used as the chosen approach for ADs. The main components will be psychoeducation and to help patients to challenge and change unhelpful cognitive distortions (e.g., thoughts, beliefs, and attitudes) and behaviors (e.g., avoidance), develop emotion regulation strategies (e.g., cognitive reappraisal), and learn coping strategies that target problem-solving. The practice is developed in several sessions that usually last between 10 and 20 sessions. Specifically, the exposure component will be considered as the first-line treatment. During the exposure component, patients will confront themselves over a long period of time, repetitively, with a feared stimulus until distress has decreased significantly by the exposure.In this condition participants will receive CBT treatment and be exposed to in vivo situations.
