About this study
Official title: Developing an Ecological Momentary Exercise Intervention: Open Trial With Patients
Multiple studies indicate that exercise is effective in treating depressed mood and reducing anxiety sensitivity. As depressive symptoms and anxiety sensitivity are elevated in individuals with anxiety and depressive disorders, exercise could help reduce these symptoms and aid in the overall treatment of these disorders. This project aims to test an ecological momentary exercise intervention (Exercise4Mood) delivered via a mobile phone application in individuals with anxiety or depressive disorders. Previous protocols have tested the acceptability and usability of Exercise4Mood in healthy participants. In Phase 1 of the study, focus groups were conducted to explore the acceptability and usability of the Exercise4Mood app. Qualitative feedback was collected and modifications were made to the app based on this feedback. In Phase 2 of the study, the Exercise4Mood app was tested in 6 healthy participants. Preliminary unpublished findings indicate that the app was acceptable and promoted increased physical activity. The aim of this protocol is to test the acceptability, usability, and efficacy (to improve mood and reduce anxiety) of Exercise4Mood in patients with anxiety or depressive disorders.
Read the detailed description
Design: A multiple baseline design will be employed: the intervention will be introduced in the 1st participant after a baseline period of 8 days, in the 2nd participant after 11 days, and in the 3rd participant after 15 days. The same pattern will be followed for participants 4-6. Participants will be in the intervention period for 21 days, 18 days, and 14 days respectively, at a prescription of 150 minutes of moderate intensity
Screening Visit:
Individuals who pass the phone screen will be invited to come to our laboratory for remaining screening procedures. At the screening visit, in-person assessment will include informed consent procedures, evaluation of psychiatric inclusion/exclusion criteria and mood, anxiety and traumatic stress disorders with the Anxiety Disorders Interview Schedule for Diagnostic and Statistical Manual of Mental Disorders (DSM) 5 Adult Version (ADIS-5) and additional informal assessment if needed (e.g. to assess eating disorders). The diagnostic assessment will be performed by a study staff member who has been trained in administration of the ADIS-5 and clinical interviewing. If a diagnostic assessment has been conducted at the Center for Anxiety and Related Disorders (CARD) at Boston University within the last six weeks, participants will be given the option to provide consent for it to be used instead (plus additional portions of the ADIS-5 if needed). Eligible participants will be assigned to one of the three conditions above (as this is a single case design, it is not randomized; participants are assigned sequentially to the conditions above). The Screening Visit, which will last 1 hour, may take place on the same or a different day as the pre-baseline visit depending on the researcher and participant's availability.
Pre-Baseline Visit (Day 1):
This in-person visit will occur on Day 1 before the baseline recording period and last 45 minutes. Participants will complete baseline questionnaires and a Physical Activity Recall interview (PAR). Participants' height and weight will be collected. Participants will be given a tutorial on and be provided with an activity and heart monitoring device to wear. Participants will be instructed to engage in their normal level of activity until their next visit. They will be instructed to wear an activity monitor during all waking hours and a heart rate monitor if they exercise. They will be scheduled for a Pre-Intervention Visit either 8, 11, or 15 days later (depending on assignment above).
Pre-Intervention Visit (Day 8, 11, 15 for Participants 1, 2, and 3, respectively):
This in-person visit will occur after the baseline recording period and last 45 minutes. Participants will be prescribed the Exercise4Mood Mobile Intervention for a period 21, 18, or 14 days (depending on assignment above) at a prescription of 150 minutes of moderate intensity (i.e. 64 percent to 76 percent of your maximum heart rate, typically achieved with a brisk walk) exercise per week (as defined by American College of Sports Medicine (ACSM) guidelines).
During this visit, they will complete an introduction to Exercise4Mood. This will involve meeting with the PI who will provide a broad overview of the intervention and training on how to download and use the Exercise4Mood app (and a number to call in case of technical difficulties). Participants will be provided with a Subject ID number and password that they will use to log in to the Exercise4Mood app. They will self-select what days and times they would like to exercise. The PI will help problem solve and ensure that their self-selected plan is feasible. The PI will note down the days and times so that text-message reminders can be sent to the participant. Participants will complete a Physical Activity Recall interview (PAR). Participants will leave the visit with the Exercise4Mood app downloaded on their personal phone and an exercise schedule for the next 21, 18, or 14 days.
Intervention Period (21, 18, or 14 days):
In the two days following the Pre-Intervention Visit, participants will be prompted to complete the Introduction to Exercise4Mood app modules at home. During these modules, they will be provided with information about getting started with exercising. This will include a list of different types of moderate intensity exercise (as listed below) from which participants will self-select what type of exercise they would like to engage in over the intervention period.
- Walking briskly
- Biking slowly
- Jogging
- Swimming leisurely
- Elliptical or other gym machines
- Stair walking
- Basketball
- Aerobic Yoga
- Tennis
- Catch/throw sports (e.g. baseball)
During the intervention period, participants will receive text message prompts to engage with the Exercise4Mood app and engage in exercise. At the end of each week that they are in the intervention, they will be prompted to complete questionnaires through the Exercise4Mood app. These questionnaires will take approximately 15 minutes to complete. During this period, they will wear an activity monitor during all waking hours and a heart rate monitor when they are exercising.
Endpoint Visit (Day 29):
On Day 29, participants will complete an in-person 30 minute visit. During this visit, they will complete an interview about their physical activity engagement, questionnaires (if they did not completed them on the app the day prior), and return the activity and heart rate monitor. Participants will be provided with referrals for mental health treatment.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Exercise4Mood InterventionBehavioural
The Exercise4Mood Intervention was designed based on principles from the Exercise for Mood and Anxiety protocol (Smits et al., 2009) and consists primarily of a mobile application called Exercise4Mood. It will be supported by text-messages, delivered through SymTrend, reminding participants about their scheduled exercise sessions and prompting them to engage with the app. Its core features include: motivational tips to encourage exercise, reminders about scheduled exercise, tracking of exercise behavior, tracking of mood before, during, and after exercise, and post-exercise positive reinforcement statements.

What is being measured
The primary outcome is the main question the study is designed to answer.
Credibility-Expectations Questionnaire (CEQ)
The CEQ is a 6-item self-report questionnaire, which assesses treatment rationale and expectancy. The scale has been used across a number of treatment trials.
Measured: Day 29
Client Satisfaction Questionnaire (CSQ-8)
The CSQ-8 is an 8-item, easily scored and administered measurement that is designed to measure client satisfaction with services. The CSQ-8 is a valid, efficient, and sensitive measure of client satisfaction and has been used across populations and mental health services (Attkisson et al, 1994; Attkisson \& Zwick, 1982).
Measured: Day 29
7-Day Physical Activity Recall (PAR)
The is an interviewer-administered procedure assessment of physical activity. Validity and reliability of this technique have been demonstrated (Blair et al., 1985; Sallis et al., 1998) and it has been used in numerous studies. This instrument has been shown to be sensitive to change in studies of moderate intensity activity (Dunn et al., 1998; Dunn et al., 1999).
Measured: Change from the start of the baseline period, an expected average of 11 days assessed weekly through the start of the intervention period, which is expected to last an expected average of 19 days for a total of 30 days
Physical Activity measured in METS (assessed via Actigraphy)
Participants will be lent an ActiGraph (ActiSleep-BT model) wireless activity monitor and Polar heart rate monitor (Polar FT) to wear during the baseline and intervention period. The actigraph is a compact and lightweight device that is worn on an adjustable elastic strap around the waist in conjunction with the heart rate monitor strap that fits securely around the participant's chest area. Participants will be asked to wear the activity monitor during all waking hours and the heart rate monitor only when they are exercising. They will return these devices at the Endpoint Visit.
Measured: Change from the start of the baseline period, an expected average of 11 days assessed daily through the start of the intervention period, which is expected to last an expected average of 19 days for a total of 30 days
Secondary outcomes (4)
Anxiety Sensitivity Index (ASI)
The ASI is a 16-item self-report instrument designed to assess one's tendency to respond fearfully to anxiety-related symptoms. The reliability and validity of this measure have been demonstrated (Reiss et al., 1986; Schmidt \& Joiner, 2002).
Measured: Change from the start of the baseline period, an expected average of 11 days assessed weekly through the start of the intervention period, which is expected to last an expected average of 19 days for a total of 30 days
Center for Epidemiological Studies-Depression (CES-D)
The CES-D scale is a short self-report scale designed to measure depressive symptomatology in the general population. The items of the scale are symptoms associated with depression which have been used in previously validated longer scales. The reliability and validity of this measure have been demonstrated (Radloff et al, 1997; Santor et al., 1995).
Measured: Change from the start of the baseline period, an expected average of 11 days assessed weekly through the start of the intervention period, which is expected to last an expected average of 19 days for a total of 30 days
PTSD Checklist for DSM 5 (PCL) - for individuals with PTSD diagnosis only
The PCL is a 20-item self-report measure that assesses the 20 DSM-5 symptoms of PTSD with total scores ranging from 0-80. The PCL is a valid and reliable method of assessing PTSD symptoms in civilian and military populations, across a range of criterion A trauma types (Weathers et al., 2013; Bliese et al., 2008; Harrington \& Newman, 2007; Walker et al., 2002).
Measured: Change from the start of the baseline period, an expected average of 11 days assessed weekly through the start of the intervention period, which is expected to last an expected average of 19 days for a total of 30 days
Depression Anxiety Stress Scale 21 (DASS 21)
The DASS 21 is a 21 item self-report questionnaire designed to measure the severity of a range of common symptoms in both depression and anxiety. There are three subscales on the DASS 21 (Depression, Anxiety and Stress) with each subscale score ranging from 0 to 42 and total scores (three subscales added together) ranging from 0 to 126.
Measured: Change from the start of the baseline period, an expected average of 11 days assessed weekly through the start of the intervention period, which is expected to last an expected average of 19 days for a total of 30 days

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Exercise4Mood Intervention in people with Anxiety and Post-Traumatic Stress Disorder, run by Boston University Charles River Campus.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Credibility-Expectations Questionnaire (CEQ) (time frame: Day 29). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jul 2017.
