Summary

This study is a multicenter prospective, parallel design, two-arm, rater-blinded randomized controlled pilot trial. Participants will be randomly assigned to one of two treatment conditions. In the first condition, treatment consists of rTMS sessions combined with Text4Support. The second condition is made up of the treatment as usual (rTMS sessions alone). The recruitment process is scheduled to last 12 months. It will involve active treatment for six weeks and follow-up period observation periods of 1,3, and 6 months for participants in both arms of the study. Participants will be recruited from four different centers for this project. Two centers (the Addiction and Mental Health clinic and the Alberta day hospital) will be from the large, sociodemographic diverse city of Edmonton in Alberta Western Canada. The remaining two centers will be in Halifax and Annapolis Valley in Nova Scotia, Canada.

Detailed description

Objective: This study aims to assess the initial comparative clinical effectiveness of rTMS with and without the Text4Support program as an innovative patient-centered intervention for the management of participants diagnosed with TRD. Methods: This study is a multicentered prospective, parallel-design, two-arm, rater-blinded randomized controlled pilot trial. The recruitment process is scheduled to last 12 months. It will involve active treatment for six weeks, observation, and a follow-up period of six months for participants in both arms of the study. In total, 200 participants diagnosed with TRD at rTMS care clinics in Edmonton, Alberta, and rTMS clinics in Halifax, Nova Scotia will be randomized to one of two treatment arms (rTMS sessions alone and rTMS sessions plus Text4Support intervention. Participants in each group will be made to complete evaluation measures at baseline, one month, three months, and six months. The primary outcome measure will be the mean change to scores on the Patient Health Questionnaire (PHQ-9). Patient service utilization data and clinician-rated measures will also be used to gauge patient progress. Patient data will be analyzed with descriptive statistics, repeated measures, and correlational analyses. Interventions: Study participants will be randomized to one of the treatment interventions (rTMS alone or rTMS plus Text4Support). During the introductory visit to the study sites, participants in both arms of the study will be given a detailed orientation about the rTMS application, and all procedures and activities within each visit will be explained to them. As part of their participation in the rTMS program, all patients will be made to complete some standard measures. Participants will be invited to the various rTMS clinics a week before the commencement of the rTMS sessions to enable them to undergo motor threshold (MT) assessments. The MT assessment is essential in that it aids in the selection of the required stimulation intensity for each patient for inclusion in the treatment. MT assessment is a measure of the minimum intensity of TMS output needed to elicit a motor response in the participating TRD patients in at least 50% of all attempts. The MT assessments will be conducted by the rTMS team of experts within the rTMS clinics in the various treatment centers and may consist of psychiatrists, nurses, and other healthcare professionals with the requisite knowledge to do so. Each TMS assessment session will take about 3-5 minutes, and the total time will be within 35-45 minutes. This visit timeline will be the same for all study participants. Overall, all study participants will be scheduled to receive 30 sessions of rTMS treatment for 6 weeks as pre-established by the Alberta Health Services Strategic Clinical Network for Addiction and Mental Health and Nova Scotia Health. Additionally, participants in the rTMS plus Text4Support group of the study will be assisted by a study team member assigned that purpose to register on to the Text4Support program. The process will require all participants in this arm of the study to input their phone numbers into the Text4Support platform that will be used to deliver the daily messages. Starting a day after enrollment, participants will receive daily supportive text messages designed by mental health therapists, clinical psychologists, psychiatrists, and mental health service users. These messages are based on cognitive behavior therapy principles crafted to enhance positively the mood of its users with depressive symptoms and other related mental health problems of concern. The messages will be pre-programmed into a software program that will deliver the messages to participants automatically to the participants' mobile phones at 10 AM (Mountain Time) and 12 PM (Atlantic Time), and each participant will receive these messages continuously for 6 weeks.

Interventions

Type	Name	Description
DEVICE	Repetitive Transcranial Magnetic Stimulation (rTMS)	rTMS uses powerful (1.0-2.5 Tesla), focused magnetic field pulses to induce electrical currents in neural tissue noninvasively, via an inductor coil placed against the scalp.
DEVICE	Repetitive Transcranial Magnetic Stimulation (rTMS) Plus Text4Support	rTMS uses powerful (1.0-2.5 Tesla), focused magnetic field pulses to induce electrical currents in neural tissue noninvasively, via an inductor coil placed against the scalp. Text4Support: Text4Support is one of the ResilienceNHope suites of supportive text messaging programs delivered by the Global Psychological eHealth Foundation \[80\]. The program allows users to receive daily supportive text messages which have been written by a team of cognitive-behavioral therapists and mental health professionals in collaboration with users of mental health services. The aim of this Text4Support depression program is to enhance positively the mood of patients with clinical depression. The program operates through the use of positive reinforcement to correct distorted or negative thought patterns.
