An interventional study of Cognitive behavioral therapy with in vivo exposure and Cognitive behavorial therapy with in vivo exposure plus SYMPTOMS-JIT in Anxiety Disorders, Specific Phobia and Panic Disorder, sponsored by Universitat Jaume I. Recruiting at 1 site in Spain. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-05-16.
Sponsored by Universitat Jaume I · Not applicable, Interventional, and Treatment
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:
Anxiety Disorders are one of the most prevalent psychological problems around the world and if not treated they tend to become chronic. Cognitive Behavioral Therapy (CBT) is the treatment of choice, being the component of in vivo exposure (IVE) the central feature. Despite its efficacy it is still a hard component to implement for the patients. Information and Communication Technologies (ICT) can help assisting and/or applying psychological interventions. The proposed study will fill the existing gap in this sense as it will assess the efficacy of a fully configurable, sensor-guided and location-based (GPS) app for the in vivo exposure component. It will also address the shortage of clinical validation studies of mHealth apps thanks to the proposed RCT. The study will expand our knowledge about the use of technologies in mental health problems and help improve the effectiveness of exposure therapy.

In this condition participants will receive CBT treatment and be exposed to in vivo situations.
Behavioral: Cognitive behavioral therapy with in vivo exposure
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
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.

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")
Time frame: 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")
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
Severity Measure for Specific Phobia - Adult
The SMSP-A is a 10-item measure that assesses the severity of specific phobia in adults during the last 7 days. Each item is rated on a 5-point scale, from 0 (never) to 4 (all of the time). Greater scores indicate more severe specific phobia, being the overall score 40.
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
Acrophobia Questionnaire
The AQ evaluates severity of anxiety and avoidance related to different situations that have to do with heights. It consists of 40 items divided into two subscales. On the one hand, there is an anxiety subscale where it is necessary to indicate the degree of anxiety, tension, or discomfort caused in the situations described, responding on a 0 to 6 point Likert-type scale ("no anxiety, calm and relaxed" - "extremely anxious"); and on the other hand, there is an avoidance subscale, where the response is coded on a 0 to 2 point Likert-type scale ("I would not try to avoid it" - "I would not bear it under any circumstances")
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
Claustrophoby Questionnaire
The CLQ consists of descriptions of 26 claustrophobic situations. Participants are asked about the degree to which they would feel anxious in these situations according to a 5-alternative Likert-type scale, where (0) is "not at all anxious" and (4) is "extremely anxious." The CLQ consists of two subscales: restriction of movement, ranging from items 1 to 12, and suffocation, ranging from items 13 to 26.
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
Fear of Flying Questionnaire II
This is a list of 30 situations related to flying that can cause discomfort or anxiety, divided into three subscales: in-flight situations, pre-flight situations, and vicarious situations. The items (each representing a situation) are rated on Likert scales from 1 (minimal discomfort) to 10 (maximum discomfort), and therefore the score ranges from 30 to 300.
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
Anxiety Sensitivity Inventory
The ASI is a scale composed of 16 items specifying a possible negative consequence to anxiety: additional anxiety or fear, illness, embarrassment and loss of control. The patient is required to rate each item in a 5-point scale, ranging from 0 (very little) to 4 (very much). The ASI has adequate test/retest reliability.
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
Fear Questionnaire (FQ)
The FQ is a 15-item questionnaire that yields four scores: main phobia, global phobia, total phobia and anxiety-depression; the total phobia score is composed of agoraphobia, social and blood-injury subgroups. It is reliable and valid.
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
Social Interaction Anxiety Inventory (SIAS)
The SIAS assesses fears of general social interaction. It comprises 20 items, rated on a 5-point Likert scale, from 0 (not at all characteristic of me) to 4 (extremely characteristic of me). Internal consistency and test-retest reliability is high.
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
Fear of negative evaluation scale
The FNE is a 30-item true-false inventory measuring anticipation of and distress about being negatively evaluated by others.
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
Social avoidance and distress scale
The SAD is a 28-item true-false questionnaire measuring subjective distress experienced in social situations and avoidance of such situations.
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
Panic Disorder Severity Scale (PDSS-SR)
The PDSS-SR is a self-report that consists of seven items rating frequency of panic attacks on a 5-point scale from 0 to 4, being the total score 28. It has good test-retest reliability and is sensitive to change with treatment.
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
Agoraphobia Inventory
This instrument measures the types of altered responses (motor (to places, means of transportation, and situations), subjective psychophysiological, and cognitive) of the patient, alone and in company, to the most common stimulus situations, as well as the variability of altered responses. Among the proposed items, patients must also indicate the symptoms that cause them the most difficulties in daily life.
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
Overall Depression Severity and Impairment Scale
The ODSIS is a five-item instrument designed to measure severity and impairment of depressive symptoms. Items are coded from 0 to 4 and are summed to obtain one total score.
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
Overall Anxiety Severity and Impairment Scale
The OASIS is a five-item continuous measure of anxiety-related severity and impairment. Items are coded from 0 to 4 and are summed to obtain one total score. The OASIS have shown high internal consistency, excellent test-retest reliability, and convergent and discriminant validity in clinical and non-clinical samples (i.e., Norman et al., 2006)
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
Behavioral Avoidance Test
Behavioral Avoidance Tests (BATs) are fundamental tools in the assessment and treatment of specific anxiety disorders, such as claustrophobia, acrophobia, panic disorder, and social anxiety. For claustrophobia, a BAT may involve progressively entering confined spaces, such as an elevator or a windowless room, while recording their anxiety level and avoidance behavior. For acrophobia, a BAT could involve gradually climbing to elevated locations, such as stairs or balconies, allowing observation of how they tolerate exposure to height. For panic disorder, interoceptive BATs are used, in which feared physical sensations (such as hyperventilating or spinning in a chair) are induced to assess the patient's reaction to bodily symptoms associated with panic. On the other hand, in social anxiety, a common task in a BAT is to ask the patient to give a speech in front of a small audience or a camera, thereby assessing their level of discomfort, physiological arousal, and avoidance behaviors.
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition)
DSM-5 criteria will be considered
Time frame: Baseline, up to 12 weeks (average)
The Clinician Severity Scale
It uses a scale from 0 (absent/none) to 8 (very disturbing/disabling).
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
Item Short Form Health Survey (SF-12)
The SF-12 is a self-report that measures the impact of health on everyday life. It comprises 12 items and it is a valid and reliable measure. The internal consistency is great.
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
Quality of Life Inventory
It is a 10-item self-report that assesses various aspects of quality of life. These dimensions are rated on a 10-point Likert scale, ranging from 1 (poor) to 10 (excellent). The dimensions include physical well-being, psychological/emotional well-being, self-care and independent functioning, occupational functioning, interpersonal functioning, social-emotional support, community and services support, personal fulfillment, spiritual fulfillment, and overall perception of quality of life. The total score is calculated as the average of all items and ranges from 1 to 10, with scores between 1 and 4.5 indicating a perception of quality of life below average, scores between 4.6 and 8.1 indicating an average perception, and scores between 8.2 and 10 indicating a perception above average. Test-retest reliability (0.89) and internal consistency (α = 0.89) are strong; discriminant validity is demonstrated in a sample of patients with mental illness.
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
Patient's Improvement Scale (adapted from the Clinical Global Impression scale, CGI)
This scale is intended to evaluate the patient's degree of progress over their initial state. The patient rates the items on a scale of 1 (much worse) to 7 (much better).
Time frame: Baseline, up to 12 weeks (average), follow-ups (3 months, 6 months, 12 months)
The Expectation of Treatment and Satisfaction with the Treatment scale (adapted from Borkovec and Nau)
These two scales consist of six items each. Participants rate these items on a scale from 0 (strongly disagree) to 10 (strongly agree). Their aim is to evaluate the treatment's ability to meet the patients' expectations, its perceived logic, its potential for treating other psychological issues, its usefulness for the patient, the likelihood of recommending it to others and its aversion. The Expectation of Treatment Scale is completed after the description of the intervention, before receiving any treatment and the Satisfaction with the Treatment Scale is completed after it is finished, assessing the patient´s satisfaction with the intervention.
Time frame: Baseline, up to 12 weeks (average)
Qualitative Interview
A semi-structured interview developed ad-hoc based on the Expectation and Satisfaction Scale (adapted from Borkovec \& Nau) following the principles specified in the CQR guidelines (Hill et al., 2005). This included different open-ended questions that assess satisfaction using the Exposure Therapy App; why they would recommend it to other people with ADs; utility; intrusiveness due to aspects of threat to confidentiality when using this technology; aspects of the tool that make it easier and/or more difficult to use.
Time frame: Up to 12 weeks (average)
Preferences Questionnaire
The Preference Questionnaire: Traditional In-Live Exposure vs. SYMPTOMS-JIT Exposure is a specially designed instrument to compare the acceptance of two exposure treatment modalities in people with anxiety disorders: one guided by a therapist in real-life settings and the other assisted by a mobile app that allows for autonomous task completion. Through ten items, the questionnaire assesses the patient's willingness to repeat each type of treatment, their preference, perceptions of efficacy, usefulness, logic, aversiveness, and recommendation to others, combining rating scales and multiple-choice options to obtain useful information in clinical or research contexts.
Time frame: Up to 12 weeks (average)
The System Usability Scale (SUS)
This scale is one of the most popular methods for assessing the usability of ICT applications. The concept of usability describes how simple it is for the users to use a technological tool to accomplish a certain task in a given situation. They must indicate how much they agree or disagree with the 10 items using a 5-point Likert scale, 1 being strongly disagree and 5 being strongly agree).
Time frame: Baseline, up to 12 weeks (average)
User Version of the Mobile Application Rating Scale
uMARS consists of 20 items assessing objective and subjective app quality, rated on a 5-point Likert scale ranging from 1 ("poor") to 5 ("excellent"). In addition, items 13-16 include the additional option of "not applicable." The objective quality score is calculated as the mean of the scores of 4 dimensions: engagement (items 1-5), functionality (items 6-9), esthetics (items 10-12), and information (items 13-16). A subjective quality score is obtained as the mean of 4 subjective items (17-20). The final uMARS subscale includes 6 items, designed to assess the perceived impact of the app on the user's awareness, knowledge, attitudes, intention to change, helpseeking, and the probability of changing the target health behavior, also rated on a 5-point Likert scale ranging from 1 ("strongly disagree") to 5 ("strongly agree").
Time frame: Up to 12 weeks (average)
