Smartphone Treatment for Suicidal Thoughts and Behavior

This study is testing a smartphone app called Therapeutic Evaluative Conditioning for Suicide (TEC-S) to see if it can help reduce suicidal thoughts and behaviors. You might be able to join if you are an adult (18+) who has had frequent suicidal thoughts recently, own a smartphone (Android or iOS), and have occasional internet access. You also need to be willing to provide an emergency contact. The study aims to see if TEC-S can reduce the desire to die by suicide over 30 days. The study is currently recruiting 60 participants in the greater-Boston, MA area.

Study design
This is a randomized controlled trial with 60 participants. You would be randomly assigned to one of two groups: one receiving active TEC-S or one receiving an inactive version.
What's involved
You would access a smartphone app daily for 30 days. This app would involve a computerized task/game and three daily check-ins on your emotions and suicidal thoughts.
Compensation
Not stated in the trial record.
Follow-up
Your desire to die by suicide will be measured through the completion of the treatment phase (day 1 through 30).
