View original scientific description
This study is testing whether it is feasible to run a larger randomized controlled trial and whether an automated text messaging program is acceptable to young adults who have suicidal thoughts. The program is designed to help participants create and use a safety plan, which is a personalized list of warning signs, coping strategies, supportive people, professional resources, ways to make their environment safer, and reasons for living. After joining and completing an initial survey, participants are randomly assigned by a computer to one of two groups. One group starts right away with the interactive safety planning text program. The other group first receives simple text messages with 24/7 crisis resources and then, after four weeks, also receives the interactive safety planning program. Participants use the text program for about four weeks and complete online surveys at the start and again over a total period of 24 weeks.
Interventions
BEHAVIORAL
Text Messaging based Safety Planning Intervention
A 4-week automated text messaging intervention designed to guide users through the steps of the safety planning process. The intervention delivers structured, interactive messages daily addressing coping strategies, crisis resources, environmental safety, family and friends for support, distraction techniques, and recognition of warning signs.
BEHAVIORAL
Facilitated Referral to Crisis Resources
Text messages that are non-interactive and contain referral to crisis services (e.g., the National Suicide Prevention Lifeline, the Crisis Text Line, and (c) the Trevor Project Lifeline).
Primary outcome measures

Time frame: enrollment to 4 weeks

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
