A new randomized clinical trial has discovered a text-messaging-based intervention can be an effective method to augment therapy services for individuals with severe mental illness. The finding is meaningful as it is estimated that almost 20 percent of the United States population have a diagnosable mental illness.

Dartmouth University researchers said the emerging technology is important as clinic-based services for mental health may fall short of meeting patient needs; face-to-face therapy may be inadequate for many reasons including limited hours, difficulty accessing care, and cost.

The new investigation is the first to use a randomized research design to investigate the impact of a texting intervention as an add-on to a mental health treatment program versus one without texting. The study appears in Psychiatric Services.

Investigators found that 91 percent of participants found the text-messaging acceptable, 94 percent indicated that it made them feel better and 87 percent said they would recommend it to a friend.

“This study is very exciting because we saw real improvement in those who utilized the text messaging-based intervention on top of normal care. This was true for individuals with some of the most serious forms of mental illness,” said co-author Dr. William J. Hudenko, a research assistant professor in the department of psychological and brain sciences at Dartmouth.

“The results are promising, and we anticipate that people with less severe psychopathology may even do better with this type of mobile intervention.”

With the COVID-19 pandemic, many people’s schedules have been upended, which may prevent individuals with mental illness from having routine access to a therapist, such as parents who have children at home.

“Texting can help bridge this gap, by providing a means for mental health services to be continuously delivered. A text-messaging psychotherapy is an excellent match for the current environment, as it provides asynchronous contact with a mental health therapist while increasing the amount of contact that an individual can have,” explained Hudenko.

For the study, the research team examined the impact of text-messaging as an add-on to an assertive community treatment program versus the latter alone. An assertive community treatment program for those with serious mental illness involves a team-based approach to help an individual with life skills, such as finding a job and housing, managing medications, as well as providing daily, in-person clinic-based services.

People with serious mental illness often experience symptoms each day for which they may need additional therapy. The study was a three-month pilot including 49 participants: 62 percent had schizophrenia/schizoaffective disorder, 24 percent had bipolar disorder and 14 percent had depression. Assessments were conducted at baseline, post-trial (three months later) and during a follow-up six months later.

Licensed mental health clinicians served as the mobile interventionists. They received a standard training program on how to engage effectively and in a personal way with participants. The mobile interventionists were monitored on a weekly basis to ensure that they were adhering to the treatment protocol. Throughout the trial, over 12,000 messages were sent, and every message was encoded, monitored and discussed with a clinician.

The results demonstrated that 95 percent initiated the intervention and texted 69 percent of possible days with an average of four texts per day. On average, participants sent roughly 165 or more text messages and received 158 or more messages. The intervention was found to be safe, as there were zero adverse events reported.

Today, there are more than 575,000 mental health therapists in the U.S. By 2025, the U.S. Department of Health and Human Services estimates that the country will be over 250,000 therapists short. ” A messaging-based intervention is an incredibly scalable, cost-effective way to help manage the enormous shortage of mental health capability in the U.S.,” added Hudenko.

The researchers are planning to study the impact of a messaging intervention in mental health on a much larger scale.
